With the improvement of economic development, solar street lighting has become an integral part of beautifying the urban landscape. Therefore, in order to ensure the Solar Street Light project, street light appliance suppliers and installers should actively intervene in the solar road lighting project in advance. The following points should be paid attention to in the street light installation:
1. In rock formations and weathered stone areas, scattered grounding and segmented grounding are difficult to meet the requirements. You can consider the galvanized flat steel and other conductors to be connected according to the design requirements. The connection should be reliable. At the same time, appropriate protective treatment and pre-embedded The foundation is reliably connected to ensure that each light pole is reliably connected to the ground. The high pole lights in solar street lights are scattered, and they mainly rely on basic grounding. If necessary, use resistance reducing agents to reduce grounding resistance. Linyi lamps wholesale
2. Hoisting operations must strictly follow the operating procedures. Pay special attention to the power grid lines and other lines around the hoisting equipment, as well as the surrounding structures. The hoisting points should be reasonable during hoisting and should be adjusted in time after positioning.
3. Pay attention to the beauty of the solar Street light pole after installation. Starting from the foundation construction, the straightness of the lamp position should be controlled based on the main line, and the line shape of the road design should be changed reasonably. The lamp pole should be straight, and the welding seam and access opening should be avoided in the main line direction, and the whole line should be consistent. The inclination of the cantilever of the light pole should maintain the coordination of direction and angle.
4. The internal fittings of the solar street lamp should be inserted tightly and firmly to avoid failure caused by loose wind pendulum and poor contact. Solar street light fixtures and lamp poles, lamp poles and cantilevers are reliably fixed. The middle and high pole lights of solar street lights must be fitted with each pole in place, the lifting frame and lamps must be reliably fixed, the lifting system must be safe and reliable, and the functions of lifting, limiting, and positioning must be complete.
5. A comprehensive understanding of the characteristics of solar street lamps, light sources, and poles. According to the actual and reference lighting standards on the road, combined with the investment budget, the solar lamps, light sources, and poles should be selected reasonably to give full play to the high efficiency and energy saving of the light sources. The advantages of light distribution and accessory combination.
6. Under the conditions of guaranteed lighting performance, appropriately increase the distance between solar street light lamps to save the number of lamps; appropriately increase the height of Solar Street Light Poles to improve the lighting effect; as far as possible, place poles in the middle of the road to save engineering cost.
7. According to the actual and geological conditions of the solar street light engineering site, design and manufacture the base of the solar street light pole and the base of the high pole lamp to ensure that the foundation is firm and reliable. Special attention should be paid to the adaptation of the embedded bolts to the reserved holes of the rod seat, accurate positioning, reasonable embedded length and outer length, and the threaded part should be properly protected to facilitate lifting and positioning.

8. In combination with road engineering, intervene in pole position selection, foundation construction and pre-embedding in advance in time to discover problems in time, make reasonable changes, ensure quality, and save investment

Solar street lights—As a segment of the photovoltaic industry, it can directly use solar energy to generate energy, save energy and save electricity, and does not require complex and expensive long-distance power transmission cables. It also has many advantages such as automatic operation and voltage safety. In recent years, it has been widely and quickly used to replace traditional street lamps. However, this market segment is experiencing short-term pains. “Solar street lights were dismantled for one year after installation”, “A town installed thousands of street lights in June 2015, and the failure rate of the lamps reached 21% after half a year.” There are more Solar Street Light projects that force maintenance every year , Resulting in a lot of waste of manpower, material resources and financial funds. For this phenomenon, the main reason is that some products that do not meet the standards are selected, there are no standards, quality inspections, after-sales, etc…. The quality assurance has become an empty talk for several years, and some companies even have a 20-year warranty… Why solar energy So many problems have appeared in the street lighting industry?
In the final analysis, it depends on the characteristics of the industry, the product production process in the industry is messy. Most of them are patchwork rather than independent R&D and production, and even many lighting companies do not have factories without certification. These companies often cut corners and shoddy materials in the production process, thus bidding at low prices, causing the industry to proliferate low-quality and low-cost garbage projects. Although solar street lights mainly rely on solar energy to generate electricity during use, which can save a lot of electricity, many projects are often implemented with the hope that they can rely on the electricity saved in later use to recover the cost year by year. If there is no warranty, it means that the huge investment cannot be recovered at all. .

Secondly, this is a sunrise industry that has not yet developed, and it is full of countless unspoken rules. According to reports, in this industry, many products of formal companies are not selected, there are no professional and technical personnel, and there is no strong management and technical ability. The project construction management can not keep up, which has caused huge pressure on the owners, and the project quality is not good. Hidden danger engineering, garbage engineering. After the construction of many intermediaries and related households was completed, they did not have enough manpower, material resources and financial support, and there was no after-sales service at all. In order to avoid the risk, the mobile phone number and the new storefront are no longer the after-sales service. As a result, there are more and more solar street lights “orphan” products on the market, which corrupts the image of the industry, seriously damages the interests of users, and causes serious road safety for residents. Big trouble.

There is no doubt that it is better than lead-acid batteries in all aspects. The most common one is lithium iron phosphate batteries. This battery does not have a memory effect like lead-acid batteries. After more than 1,600 recharges, the storage capacity of the battery is still It can reach 85%. Compared with lead-acid batteries, lithium batteries have the advantages of lightness, large capacity and long service life.
Lithium batteries are actually lithium-ion batteries. The common ones are simply cobalt-lithium, manganese-lithium and iron-lithium. In the past, the safety problem of lithium batteries refers to cobalt-lithium, but after continuous technological progress, the current manganese-lithium and iron-lithium can fully guarantee Safety issues, otherwise, don`t most of the products that use lithium batteries such as power tools and IT products around us become time bombs? Especially iron-lithium batteries will be the most efficient batteries used in electric vehicles in the next few years, such as BYD. The iron batteries used in electric vehicles are actually lithium iron batteries.
The cycle life of lead-acid batteries is about 300 times, the cycle life of manganese-lithium batteries reaches 500-800 times, the cycle life of iron-lithium batteries reaches 2000 times, and Toshiba`s new Lithium Battery reaches more than 5000 times.
The charging time of lead-acid batteries is generally more than 6-8 hours. The lithium battery uses a special charger, and the charging time only needs 2-3 hours. Toshiba’s new lithium battery can recover 90% of the power in a few minutes.
The most important cost issue is that the cost of lithium battery is actually not much more expensive than that of lead-acid. In the case of small energy storage batteries, lithium battery is more competitive than lead-acid. The reason why lithium battery is currently expensive is that its technology is still improving. The old production process is quickly eliminated. In order to recover costs in a short time, manufacturers must have a higher profit rate than other industries. When the technology is mature and the industrial scale is formed, lithium battery The price will definitely be cheaper than lead acid.
Of course, technology is constantly improving. The replacement of lead-acid in lithium batteries is not the direction of future batteries. Lithium batteries are not revolutionary technological progress. The scientific community is more inclined to the direction of fuel cells. In the foreseeable future, fuel cells may be The most ideal solution for human energy storage.
In general, the advantages of solar lithium battery street lights:
1. Adjustable Solar Panel bracket to maximize light collection;
2. Green and environmental protection;
3. The lithium battery is convenient to install directly under the solar panel, which is small in size and light in weight to reduce construction costs;
4. Long service life is 3-5 times that of traditional energy storage lead-acid batteries.

Lithium battery solar street lights should be widely used, such as lithium battery solar street lights, lithium battery solar high pole lights, lithium battery Solar Garden Lights, lithium battery solar antique garden lights, lithium battery solar LED lights, lithium battery solar stadium lights and so on. Baorun Lighting Group Co., Ltd. is a manufacturer of outdoor lighting products integrating design, R&D, production, sales, construction and installation services. It mainly produces various lithium-ion solar street lights, solar street lights, road lights, high pole lights, and landscape lights. , Courtyard lights, lawn lights, underground lights, scenic spot lighting, landscape lighting, building lighting engineering design and construction, etc.

Solar street lights are favored by more people due to widespread promotion, but some consumers are not very clear about solar street lights. When buying, they are often blindly seeking high brightness, shape, and low price, ignoring the two most important points of lighting products. : Quality and cost performance. We are very fortunate to have 10 years of experience in Solar Street Light brand manufacturer Ou Shang Lighting, to explain to us the four major misunderstandings of consumers choosing solar street lights.
Misunderstanding 1: Blindly pursue the high brightness of solar street lights
We all know that different occasions have different lighting standards, and the blind pursuit of high brightness is not only wasteful, but also may cause harm to people. Therefore, first confirm the lighting needs and then choose the solar street lights that meet your needs.
Misunderstanding 2: Nominal power and operating power of solar street lights
Because solar street lights can be controlled intelligently, the power can be automatically adjusted according to requirements at different time periods, so their use areas and rated power are different.
Misunderstanding 3: There is a difference between the actual service life and the nominal data
Generally, the nominal life of LED can reach 100,000 hours, but the solar street light system is composed of solar panels, batteries, controllers, light poles, light sources, etc. The life of solar panels is 25 years, and the life of batteries is three to three. In five years, the life span of the solar street light controller is two to five years.
Misunderstanding 4: Set the product at the price.
Price reflects the combination of cost, quality and brand value. It is closely related to the configuration. Ultra-low-priced solar street light products will inevitably not guarantee the use, but the ultra-high-priced solar street light system will definitely have configurations that exceed the use requirements or false high components and waste money.

Therefore, reasonable configuration is a very critical link in the purchase of solar street lights. We need to be cautious and stop thinking about these four misunderstandings.

The stability of solar street lights As the society continues to advocate green, low-carbon, and energy-saving life, people have gradually increased their environmental awareness. Moreover, solar energy has also gained popularity, as a new type of safe and environmentally friendly energy that is “inexhaustible and inexhaustible”.
Solar energy has also made a great contribution to street lights, so solar street lights have slowly begun to have their current market position. If you want to popularize solar street lights, you must understand the characteristics of our solar street lights.
1. Will not turn off suddenly: Solar street lights use the solar energy of the sun as energy source, charge the battery when the sun is out, and when the environment is dark to a certain degree, the battery will provide power for the street lighting work, so it will not When the lights are turned off suddenly, solar street lights use DC power.
2. The quality of LED light source: The light source of solar street lights generally uses LED lamp caps. The LED lamp caps have a long lighting life (about 50,000 hours), and they will not emit excessive heat when used, which is extremely Greatly extend the life of the light source.

3. It can also be used normally in consecutive rainy days: solar street lights use solar energy to generate electricity, so they can also perform normal lighting work on days without sunlight, and Hongchuang Energy, as a Solar Street Light manufacturer, is engaged in solar street lights When designing the plan, these issues will also be considered, and then through the communication with the customer, according to the customer`s local rainy and cloudy day conditions, the appropriate street lamp accessories will be configured to solve the problem that the local area can work even on the most continuous cloudy and rainy days. As for the situation where there is no electricity and lights out.

Solar street lights are so popular nowadays, so what is the reason why they are so popular? Let’s listen to the manufacturer’s answer for you:
1. For better construction of the city, in the city are generally changed to solar street lights. The price of solar street lights is reasonable. The installation procedures of traditional street lights used in the past are more complicated, and the circuit needs to be laid, and the power consumption is relatively compared High, and use a relatively large wattage street lamp head, not only dim the light, but also not conducive to the illumination of the city.
2. The price of solar street lights is relatively low, energy-saving and environmentally friendly, and the installation procedures are simpler than traditional ones. At the same time, there is no need to lay very complicated circuits. The price of solar energy mainly consists of four parts. Controllers for street light poles, battery panels and solar street lights.
3. Now that saving resources has become a concern of the whole world, solar energy was invented to bring great convenience to human life, and our country’s solar radiation is relatively high, because solar energy is very abundant. The price of solar street lights is uneven, and the price is about two hundred to one thousand yuan. Compared with traditional street lights, the price is much cheaper. In addition to the different materials of the street lamps, the reason for the inconsistent prices is the different brands they choose. For consumers, brand is also a guarantee of quality. Most solar street lights can illuminate for eight to nine hours as long as they are fully charged, so you can refer to the quality of solar street lights based on this when choosing. When choosing street lights, you must consider the road section to be installed. Different road sections and environments are different, so the specifications to be selected are also different. For example, the width of rural roads is less than ten meters, and most of them are between four and six meters. Therefore, the wattage selected by the lamp holder should be able to illuminate the road with this width.

4. Description of the working principle of solar street lights: solar street lights during the day are under the control of the intelligent controller, the solar panels absorb solar light and convert it into electrical energy under the control of the intelligent controller during the day. The solar cell components charge the Lithium Battery during the day and provide power at night. Supply power to the LED light source to realize the lighting function. The DC controller can ensure that the lithium battery is not damaged due to overcharging or over discharging. It also has functions such as PIR human body induction, light control, time control, temperature compensation, lightning protection, and reverse polarity protection.

In fact, when we appraise the quality of the high-pole lights, we are testing the quality of these accessories, because only when the quality of each component is not a problem, we can prove that the high-pole lights are qualified and there is no quality problem. So what accessories do high pole lights consist of? Why is one indispensable? Today, Jinchuan Lighting will give you a detailed introduction:
1. The electric lifting system is composed of an electric motor, a hoist, three groups of hot-dip galvanized steel wire ropes and cables.
2. The functionality is mainly frame structure, and some are mainly decorated with steel through and steel pipe. Lamp poles and lamp panels are treated with hot-dip galvanizing.
3. The lighting electrical system is equipped with 6-24 400w to 1000w metal halide (white light), floodlight, floodlight lamps, and the computer time controller can automatically control the switch light time and partial or full lighting.
4. The guiding and unloading system is composed of guiding wheels and guiding arms to ensure that the lamp panel will not move laterally during the lifting process, and ensure that the lamp panel can be automatically detached and locked by the hook when the lamp panel is raised in place.
5. Lightning protection system: a 1.5-meter-long lightning rod is installed on the top of the lamp, and a 1-meter-long grounding wire is installed on the underground foundation and welded to the underground bolt.
6. The light pole is an octagonal, twelve-row, and eighteen-sided pyramidal pole, which is cut, bent, and automatically welded to form a high-strength steel plate. The general height is 25, 30, 35, 40 and other specifications, and the design is highly wind-resistant The capacity can reach 60 meters per second, and each specification is composed of 3 to 4 plug-in sections.
The seemingly very simple high pole lamp, its accessories are not simple, every aspect occupies a very important position, so in the later use process, we must insist on regular maintenance and maintenance!
Light pole packaging and transportation requirements: After talking about so many high-pole light accessories, let’s take a look at the transportation of high-pole light poles!
Packaging and transportation instructions for high pole light poles:
1. Packaging
Because the special product packaging such as the weight and shape of the light pole is different from that of ordinary lighting products, our company uses the following methods:
a. Bubble bag wrapping method, this method is simple packaging; suitable for special vehicle transportation, minimize the number of turnover during transportation to avoid tearing the bubble bag during loading and unloading and causing scratches on the light pole.
b. Snake skin bag packaging, which is better than bubble bag packaging;
c. For long-distance transportation or export, use bubble bag + snake skin bag packaging; avoid scratching the light poles during the turnover process;
2. Light pole transportation
Light poles should be large objects. In the case that the quantity is not enough for the entire vehicle, we will choose the dedicated line logistics distribution of the customer address; to reduce half-way turnover and avoid light pole scratches; if the goods are enough for the entire vehicle or the customer requires direct transportation to the site The company will find the truck to be transported to the construction site.
On the problem of scratches on the light pole:

Because light poles are large objects and heavyweight items, they are scratched in different degrees during transportation and installation. The way to solve this problem is that our company will provide the corresponding number and correspondence according to the number of light poles when the light poles are shipped out. The color is self-painted. For example, the color of the light pole is the color assigned by the customer. Our company will equip the corresponding color plastic powder for the customer to remedy.

Nowadays, many areas have used high-pole lights. The high-pole lights have a large illumination range. They are necessary outdoor lighting street lights for squares or piers. However, many people don’t understand the calculation standards of high pole light poles. Today, the high-pole lamp manufacturers will briefly talk about the inspection standards for high-pole lamp poles. There is currently no standard for the structural strength calculation of the poles of high-pole lamps in our country. Generally, it is carried out with reference to the “Code for Design of Tower Structures”, “Code for Loads of Building Structures” and “Code for Steel Structure Design”. The checking calculations in this section are only checking calculations for seamless steel pipe rods and welded taper rods. The strength check calculation of the lamp pole mainly considers the effect of wind on the pressure is 0.56kN/, that is, the design is based on the tenth wind speed (30m/s). The seismic intensity of light poles shall be fortified according to the seismic intensity of 8 magnitude. When the designed seismic intensity is greater than or equal to 7, the seismic intensity shall be checked. The calculation method can be the bottom shear method.
As for the requirements of seismic design, the site and foundation that are favorable for seismic resistance should be selected as far as possible, and the lamp body should be simple in shape, and the mass and rigidity should be symmetrically and evenly distributed. Try to make the center of mass and the rigidity center coincide to ensure the integrity of the structure. High-strength material. Seismic check calculations, for cylindrical structures, chimneys, water towers and high-pole lights, the bottom shear method and the approximate simplified method can be used.

It can be seen from the calculation that the external force of the high pole lamp is mainly wind load, so the calculation of wind load is the key. Under the action of wind load, all anchor bolts on the bottom flange of the light pole are sheared by the wind. Because the wind load acts on the light pole, the foundation bolts of the bottom flange of the light pole are roughly regarded as half tension and half compression .

01
Misunderstanding of the “definition” of no main light
Without the main light design, 90% of people will literally understand that there is no main light, such as chandeliers, ceiling lights, etc., and the entire indoor space relies on auxiliary light sources (spotlights, downlights) to obtain illumination.
However, there is no main lamp design in the designer’s mind, and there are two other meanings:
1. There are chandeliers or ceiling lights, but they are only used for decoration, without light sources or not turned on, and rely on auxiliary light sources to obtain lighting functions.
2. There is a main light and a light source, which can be turned on, but the brightness is very low, not enough to support the lighting function of the entire space, and the auxiliary light source can provide indoor space lighting at the same time.
The above interpretation can be called a design without a main light, but in summary, it is necessary to have an auxiliary light source to provide illumination. It does not matter whether the main light is present or not, so no main light is not an appropriate name. It is just a form of lighting. At the beginning, it may be a marketing method for designers or design agencies to get a “tall” title and attract more trendy people.
Therefore, no main lamp design has become a trend of “word of mouth” by the younger generation of trendy people, and it is deeply “misunderstood”. The author thinks that no main lamp design can only be misunderstood as its literal meaning. It should be understood as a kind of “style” of lighting, just like in decoration, light luxury style, black and white gray style, etc., non-main light should be called non-main light style design in the future.

02
Misunderstanding of “Use” Without Main Light
Some time ago, a friend consulted about the design of a masterless lamp at home. In the ceiling position, several downlights and several spotlights are needed, how to arrange them and other issues. I felt that there was “sufficient speech” at the time. The lamp design style has been “misunderstood” to the extent that it can be achieved simply by installing a few spotlights and downlights on the ceiling?
Strictly speaking, the design style without main light should originate from coffee bars, bars and other places. In order to create a mysterious and warm atmosphere, “general lighting”, “partial lighting”, “directional lighting”, “key lighting”, “Flood lighting“, “transitional lighting”, “landscape lighting” and other methods. Later, this lighting method was used by designers in the high-rise space with higher floors, and finally gradually developed into the application of various apartment types. In fact, this trend is misunderstood, not all units are suitable for the design of the style of no main lamp.
①The unit type with too low floor height is not necessarily suitable for the design without main lamp style.
②Among family members, those with elderly and children are not suitable for the design style without the main lamp.
③In the long run, although young newly-married couples like the lighting of this atmosphere, with the baby in the future, this design without the main lamp will be very tasteless.
If you really like the style of the main lamp, it is recommended to install a main lamp, even if it is not turned on normally, it is better than regretting it in the future. If you want to use the main lamp style well, you must first understand the basic optics and then interpret the main lamp. Main lamp style, and master the expression form of design style without main lamp.

03
Essential knowledge of optics
If you want to understand the expression of the design style of the headless lamp and interpret it, you need to understand the basic knowledge of light first, because in the following explanation, many such professional terms will be used, and these terms will be briefly explained below.
(1) Physical properties of light
Deciphering light from the perspective of physics can roughly start from seven different aspects, namely “illuminance”, “color rendering”, “color temperature”, “shadow”, “stability”, and “glare”.
①Illuminance: refers to the luminous flux received by the illuminated object per unit area, in lux (LX). In indoor lighting design, the illuminance of the area is usually combined with the purpose of the illumination area.
②Light color rendering: refers to the color difference (Ra) of the same object under the illumination of different light sources; for a simple example, the color rendering of sunlight is the best (color rendering index 100), and the incandescent lamp index is 97 , Followed by the fluorescent lamp index is 80~94; but in the design of indoor lighting, the higher the color rendering, the better. For example, the design without the main lamp style uses a lot of light sources with lower color rendering to enhance the atmosphere .
③Color temperature: In simple terms, in the same environment, the higher the color temperature of the light source, the colder and colder it feels, and the lower the color temperature, the warmer it feels.
④Shadow: When there is light, there must be shadow, and the design style without main light mainly uses the atmosphere created by shadow.
⑤ Stability: First, the stability is to pay attention to the load of the electric voltage to avoid the light source flickering, and the other is to pay attention to the airflow to avoid the swing of the lamp.
⑥Glare: Glare is a kind of visual induction caused by the physical properties of light, which makes the eyes feel extremely uncomfortable and accelerates people’s visual fatigue. Therefore, the choice of light source needs to consider glare instead of the main light style. Design is the easiest to cause dazzling, and it is mainly because of this. Therefore, the author thinks that without a main lamp, you need to choose carefully and do not blindly follow the trend. Therefore, if you want to design without a main lamp, you must have a professional lighting designer Guidance can be.

04
Interpretation of the different expressions of the design style of no main lamp
Without the main light design, the performance of lighting can be roughly divided into nine categories, namely general lighting, partition lighting, local lighting, mixed lighting, directional lighting, accent lighting, reflective lighting, transition lighting and landscape lighting, each The lighting forms all have different design principles.
Only by using these nine items reasonably can you achieve a perfect design style without a main lamp, instead of just relying on a few spotlights and downlights to create a feeling of “darkness”, the following nine kinds of The lighting form is briefly introduced.
(1) General lighting
General lighting is the most basic form of lighting. It does not need to consider too many lighting factors. The main purpose is to bring a relatively balanced lighting effect to the interior.
In the non-main light design style, in order to achieve the effect of general lighting, multiple identical lighting fixtures are arranged in a relatively uniform form, so that the space covered by the fixtures can obtain a relatively uniform lighting effect after the power is turned on. This kind of light expression is usually used in the lighting design of corridors and other areas in ordinary lighting design.
(2) District lighting
District lighting is to increase the illuminance of a certain area in the same space according to actual living needs, and the lighting layout used in this area is designed according to general lighting, so that the illumination of the area with increased illuminance is finally balanced.
In the home space, the use of partitioned lighting can improve the quality of indoor lighting to a certain extent, save unnecessary waste and ensure the efficiency of light source utilization.
In the design style of no main light, a large number of zoning lighting methods are used, and multiple light sources are used to make the light softer. We must pay attention to the multiple light sources mentioned here. It is not many downlights in misunderstandings, but may also be Long chandelier.
(3) Local lighting
If the zoning lighting cannot meet the occupants’ lighting needs for a certain area, or the general lighting cannot illuminate the area and it is not convenient to install the zoning lighting fixtures, then the lighting arrangement of the local lighting is a good choice.
The local lighting design is suitable for areas with high lighting requirements, such as bedside lamps and desk lamps.
In some larger spaces, there is usually more than one local lighting area. When designing without the main lamp style, I prefer to distribute multiple lighting fixtures in multiple parts of the space to play a role in decorating the space.
(4) Mixed lighting
The light expression form composed of general lighting, district lighting, and local lighting is called mixed lighting.
When designing lighting for large-sized indoor spaces, the living room area usually adopts a mixed lighting design, and the mixed lighting layout used is often relatively complicated, but we can make the lighting layered by reasonable layout. Be organized to avoid unnecessary waste of light sources.

to sum up
The author believes that no main light design should be understood as a style. Strictly speaking, it should be called “no main light design style”, instead of being gradually misunderstood as no main light. Use a few downlights and spotlights, simple A light atmosphere can be formed by a single combination; the correct style design without the main light is relatively strict and complicated, and it requires general lighting, partial lighting, directional lighting, accent lighting, flood lighting, transition lighting, landscape lighting, etc. The combination of these methods, mutual cooperation and reasonable collocation can be called the real headless style. At the same time, it is not suitable for all families. You must carefully choose the headless style design according to your family members and floor heights. Therefore, it is recommended not to blindly follow the trend, which will cause light pollution in the indoor space.

As a new energy product, solar street lights have the advantages of energy saving and environmental protection, but the high cost and maintenance cost have always been important reasons for people’s fear. Many friends hope that the price of solar street lights can be lowered. Then how to lower the price and what impact will it bring What? The editor below will share it with us.

For Solar Street Light work
Many small workshop-style manufacturers have no competitive advantage in their products, so they gain sales by lowering the price of solar street lights. Originally, a reasonable reduction in the price of products would have a beneficial effect on customers or work. However, these small workshop-type manufacturers did not have the advantage of formal solar street light manufacturers in the production process, so they often reduced the production of solar street lights. Standardization, or cutting corners, false standard equipment and selection of unconventional production methods. Through these methods, the price of solar street lights is too low, so that the price of the entire mall is messed up. We all know that many customers still expect to choose cheap products, so more solar street light manufacturers participate in this low-cost game By the way, the shopping malls are gradually full of low-cost solar street lights. And we all know that the quality and service life of such low-cost solar street lights are not ambitions in all aspects. Overnight, the overall reputation of solar street lights will become worse and worse, and then the sales of the entire work will decline.

or customers
As mentioned above, the price of solar street lights is too low, and its quality and service life are definitely not ambitions. Low-cost solar street lights generally need to replace solar batteries or solar lamps after one year of use. Customer needs are facing the replacement of solar street light accessories every year The trouble and trouble, not to mention the annual replacement of accessories is also a maintenance expense. The standard solar street lights are generally used for 4 years without any problem. Therefore, strictly speaking, low-cost solar street lights do not benefit customers in terms of price, but increase customers’ worries.

To sum up, the editor will talk about the impact of reducing solar street lights from the perspective of solar street lights and customers. If you want to know more related information, please pay attention to this site.

The differences between solar LED Street Lights and integrated solar LED street lights are as follows

①Traditional solar LED street lights are divided into several parts, and all the integrated parts will be combined together to make the volume smaller. Compared with equipment, integration is more convenient

②Lithium Battery solar Led Street Light and integrated solar LED street light are made of lithium iron phosphate battery and ternary lithium respectively. The integrated solar LED street light has a higher voltage and is more helpful for power supply.

③The conversion rate of their electronic boards is also different. The conversion rate of the electric solar panels of the integrated solar LED street lights is higher, so that the integrated charging is faster under normal light conditions.

④Solar LED street lights are normally light control + time control, and the integration has more human body induction, which is more environmentally friendly and energy-saving.

The integrated solar LED street light has a simple structure, small size and light weight, which is convenient for transportation and equipment.

1. Incandescent lamps, tungsten halogen lamps (note that there is also a metal halide lamp, with different principles and gaps in color rendering), low-quality energy-saving lamps, and low-quality LEDs. The strobe is more obvious (keyword: strobe depth). This information is basically not available on the Internet. If you are interested, you can watch the measurement results of EERE and other institutions. You can also use the photosensitive element to connect to the oscilloscope. Anti-stroboscopic algorithm of the camera) look. In addition, the stroboscopic frequency of incandescent lamps, halogen lamps, and energy-saving lamps is not 50Hz, but 100Hz. Energy-saving lamps with high frequency tens of thousands of flashes per second are actually 100Hz. Brainless publicity in the market has confused the operating frequency of the switching power supply with the frequency of the output ripple.

2. The color rendering of incandescent lamps and halogen tungsten lamps seems to be perfect, but this is because the color rendering index itself uses black body radiation as the benchmark when the color temperature is low. In fact, in recent years, academia has advocated examining the two factors of GAI and CRI as standards, while incandescent and halogen tungsten lamps are not very good in GAI. The specific manifestation is that they have poor color resolution and feel annoying. For serious study and work, it is recommended to use a higher color temperature light source, such as 4500K-5000K color temperature, which is close to the natural sunlight outdoors, which is more suitable.

3. Theoretically speaking, LED should not flicker, but due to cost and PF (power factor correction) reasons, most of the current drivers will flicker.

In short,

If you want to be economical and cost-effective, it is recommended to choose a three-primary energy-saving lamp with a color temperature of 4500-5000K.

In the early stage of street lamp procurement, many customers will ask how much solar street lamps are, whether you are a street lamp manufacturer, such as these questions, customers do not understand the production process of Led Street Lamps, nor do they understand the structure and principle of street lamps, just choose LED solar street lights are low-priced products. Of course, some customers have to purchase cheap LED Street Lights because they won the bids at low prices. However, this behavior is undesirable. This will only cause a lot of unnecessary troubles for the maintenance of street lights in the future, including the after-sales of the manufacturers, and there is no corresponding profit. How can there be high-quality after-sales service?

The reason for the low price of LED solar street lights is probably the use of inferior methods such as cutting corners to reduce product costs. How can there be no problems with such LED Lamps in the later application? How can the maintenance cost be low in the later period, and the safety can not be guaranteed, which may eventually lead to customers repurchasing. This is tantamount to wasting financial resources, material resources and manpower.

Therefore, when choosing a suitable price for LED solar street lights, we must choose LED Solar Street Light manufacturers that have passed the qualification certification and product quality system certification. You can also inspect the manufacturer’s strength on the spot, check the welding and polishing of the goods, so that you can find a good manufacturer and buy a reliable LED solar street light!

How does the reflective film reflect light? Many people are curious about how the reflective film reflects light. When the light shines, it will reflect so striking light. In fact, this reflection principle is not very difficult. The transportation facility manufacturers come to make a popular science for everyone.

In fact, if you have bought products such as road reflective film, it is not difficult to find that there are countless densely packed small particles on the reflective tape, and it will come off if you scrape it with your nails. This kind of fine particles, we call glass beads. Since the glass beads are spherical, and the light projected on the screen is similar to parallel light, when it hits the apex of the spherical shape, the angle of incidence is very small. Part of the light is reflected, and the other part is split and then reflected again. Disassembly occurred and returned to the air and returned to the front of the screen. This also gives us a feeling of reflection.

After the introduction of the above content, do you already understand the principle of road reflective film? Since its introduction, reflective film has made a great contribution to social public safety. With the development of the national economy, the improvement of people’s living standards, and the enhancement of safety awareness, reflective materials will be more widely used in the Chinese market in the future. So if you need this, please remember to contact us in time.

The energy used by a normal street lamp is electricity. Let`s take a 60w LED street lamp as an example. Its annual electricity bill is only 20% of that of a 250W ordinary high-pressure sodium lamp. That is to say, if the annual electricity bill for an ordinary lamp is 1,000 yuan, then the LED street lamp is only 200 yuan. Electricity bill. It is currently the best energy-saving lighting product.

Then there are the advantages of the facilities
The function of LED Street Lights is only 25% of ordinary street lights, and the copper cable section is only 1/3 of ordinary street lights, which is a saving. This is the initial investment cost

In normal use, Led Street Light 60W lamp can reach the illuminance of 250W high voltage street light. This effectively reduces the power used. Therefore, all solar street lights use LED street lights
Because the power of the LED street lamp is low, the temperature generated is relatively low, and no high temperature is generated. These have undesirable consequences, such as the blackening of the lampshade, these

Because there is no infrared and ultraviolet in the LED street lamp, there is no radiation, and no light pollution will be produced. There will be no metal harmful, so its environmental protection is relatively high

Therefore, in the current street lamp market, when designing street lamps, Led Street Lamps are the first.

Ten global LED lighting certification standards:
3C certification
The full name of 3C certification is the “Compulsory Product Certification System”. It is a product conformity assessment system implemented by the Chinese government in accordance with laws and regulations to protect consumers’ personal safety and national security, strengthen product volume management. 3C certification is mainly trying to pass a package of solutions such as “unified catalog, unified standards, technical regulations, conformity assessment procedures, unified certification marks, and unified charging standards” to completely solve the long-standing Chinese product certification system. Review, repeated charges, and the issue of whether certification behaviors are not separated from enforcement behaviors, and establishing technical regulations, standards and conformity assessment procedures consistent with international rules can promote trade facilitation and liberalization.

ISO9000 certification
ISO9000 quality system certification certification bodies are authoritative organizations recognized by the national accreditation body, and the audit of the company’s quality system is very strict. For the enterprise, quality management can be carried out in accordance with the internationally standardized quality system that has been strictly audited to truly meet the requirements of rule of law and science, greatly improve work efficiency and product qualification rate, and quickly improve the economic and social benefits of the enterprise . For the outside of the company, when the customer learns that the supplier implements management in accordance with international standards, has obtained the ISO9000 quality system certification, and has strict audits and regular supervision by the certification body, they can be sure that the company can stably produce qualified products and even Trustworthy companies with excellent products can safely conclude supply and marketing contracts with companies and expand their market share.
UL certification

UL is the abbreviation of Underwriters Laboratories of America. The UL Safety Testing Institute is the most authoritative in the United States and the largest private organization engaged in safety testing and appraisal in the world. It is an independent, profitable professional organization that conducts experiments for public safety. It uses scientific testing methods to study and determine whether various materials, devices, products, equipment, buildings, etc. are harmful to life and property and the degree of harm; determine, write, and issue corresponding standards and help reduce and prevent life Data on property losses, while conducting fact-finding research business.
FCC certification

The Federal Communications Commission of the United States was established by COMMUNICATIONACT in 1934. It is an independent agency of the US government and is directly responsible to Congress. The FCC coordinates domestic and international communications by controlling radio broadcasting, television, telecommunications, satellites and cables. Many radio application products, communication products and digital products require FCC approval to enter the US market. The FCC committee investigates and studies the various stages of product safety in order to find the best way to solve the problem. At the same time, the FCC also includes the testing of radio devices and aircraft.
CE certification

CE certification
“CE” mark is a safety certification mark, which is regarded as a passport for manufacturers to open and enter the European market. In the EU market, the “CE” mark is a compulsory certification mark. Whether it is a product produced by an EU enterprise or a product produced in another country, if you want to circulate freely on the EU market, you must affix the “CE” mark.

MET certification
MET certification mark is applicable to the US and Canadian markets: The MET mark with C-US indicates that the product has passed the test, meets the applicable standards of the US and Canada, and can enter both markets at the same time.

CB certification
The CB system (IEC system for conformity testing and certification of electrical products) is an international system operated by IECEE. The certification bodies of each member country of IECEE test the safety performance of electrical products on the basis of IEC standards. The test results are the CB test report and CB The test certificate is a system of mutual recognition among the member states of IECEE. The purpose is to reduce international trade barriers due to the need to meet the certification or approval criteria of different countries.

CSA certification
CSA is the abbreviation of the Canadian Standards Association. It was established in 1919 and is Canada’s first non-profit organization dedicated to the development of industrial standards. Products such as electronics and electrical appliances sold in the North American market need to obtain safety certification. At present, CSA is the largest safety certification body in Canada and one of the most famous safety certification bodies in the world. It can provide safety certifications for all types of products in machinery, building materials, electrical appliances, computer equipment, office equipment, environmental protection, medical fire safety, sports and entertainment.

GS certification
GS means that safety has been certified, and it also means German safety. GS certification is based on the German Product Safety Law (GPGS) and is a voluntary certification for testing in accordance with the EU unified standard EN or German industrial standard DIN. It is a recognized German safety certification mark in the European market.

VDE certification
The VDE Testing and Certification Institute in Offenbach, Germany, is a research institute affiliated to the German Institute of Electrical Engineers, established in 1920. As a neutral and independent organization, VDE laboratories inspect and certify electrical products in accordance with German VDE national standards, European EN standards, or IEC International Electrotechnical Commission standards based on applications. In many countries, the VDE certification mark is even more famous than the domestic certification mark, especially recognized and valued by importers and exporters.

The first step: cell inspection
The cell inspection process is an electronic current-voltage measurement system used to identify the performance of photovoltaic cells. The tester uses a variety of current and voltage combinations to sample the cell under the variable impedance power generation. The performance of the cell depends on the measured data of the output current-voltage relationship when it is illuminated by light. This relationship is called the “current-voltage curve” and can be obtained by exposing the cell to a constant level of light source and changing its external impedance to change the cell’s current-voltage value. Creating a current-voltage curve requires multiple current-voltage point data, and an external trigger function device can be used with the pulse solar simulator. This allows the tester to create multiple continuous pulses (usually 10-100 selection points) to complete the current-voltage curve measurement, generally input 100V~240VAC, 50/60Hz. A PC computer needs to be used as a controller to control this current-voltage measurement system.

Step 2: Weld the cells into strings
The manual stringing procedure requires a stringing station. A stringing station has two working positions. The stringing station is equipped with a heated welding plate, which can reduce the heat tension caused during the welding process. The string welding technique is compact and coordinated and does not require more external space. Cells of different specifications can be welded on the stringing station.

The third step: component layering
Manual component layering process: After the cells are connected in strings, they are moved and placed on a light table that can test their electronic performance. At this stage, it is also checked whether there are problems between the cell connections.
Then, the battery slices are placed in series on a board that has been covered with a sealing film, and then another sealing film and a TPT film are covered on it. The next step is to use laminating equipment to merge all the layers together.

Step 4: Laminating procedure
The automatic laminating process requires a laminator equipment that manufactures the heart of each solar module. During the lamination process, the series-welded cells are sealed between a glass plate and the TPT or between two glass plates under vacuum conditions at a temperature of 150 °C. In this process, it is most important to ensure the same heating temperature for each layer area. If the temperature between the areas is different, even a few degrees difference will cause the danger of uneven adhesion of the sealing material, which will cause the components to be used The consequences of being infiltrated by water after a period of time, such as use on the roof, may result in the need to replace new components.

The laminator is compact and easy to monitor, and does not require additional external equipment such as vacuum pumps or heaters. The control panel makes the program setting of the whole process flexible and can be fully controlled.

How big is the Solar Street Light source installed, and what factors does the size of the light source have to do with? Let’s briefly introduce the main factors that affect the size of the light source: the rigid requirement of illuminance, the height of the light pole or the width of the road. Under normal circumstances, the main factor of the size of the solar street light source is this factor, but there is no industry standard in the market. In accordance with national standards, many solar street light source sizes are not standardized. Here we want to introduce the height and width of street lights and the light source size of the light source. Normally, some people will ask, what is the distance between solar street lights?

In accordance with the standards of new rural construction, here is a plan to recommend the solar street light source:
5m solar street light with light source: 9W-18W;
6m solar street light with light source: 18 watts -30 watts;
7-meter solar street light equipped with light source: 30 watts-42 watts;
8 meters solar street light equipped with light source: 42 watts -60 watts;
9m solar street light equipped with light source: 60 watts-80 watts;
10m solar street light equipped with light source: 80-100 watts;

This light distribution method is the most commonly used scheme in the construction of solar street lights in the new countryside. How about the brightness of the light source equipped according to this standard? A very vivid sentence is: it`s okay to read underneath, so if you install solar street lights for new rural construction, you can design according to this standard, so that in addition to meeting the requirements of normal lighting, it can also save engineering costs; some The project contractor doesn`t understand, and blindly says to install a little brighter, the bigger the better, in fact, it`s not the case. The cost of solar street lights has a lot to do with the configuration plan. Unlike ordinary street lights, it`s just a problem of changing the light source from 18 watts to 100 watts. The cost can`t add much, but if the light source of the solar street lamp is changed from 18 watts to 100 watts, the cost of the whole set will increase exponentially, because the solar street lamp is a set of system, and each component will change with the change of the corresponding element. The cost is constantly changing; therefore, to make a professional solar street light program, you must refer to the specific engineering case program and experience the brightness of the program firsthand!

1. The general urban street lamp monitoring poles are manufactured in accordance with the height of 6 meters and the cross arm of 1 meter. The community monitoring poles are customarily manufactured with a height of 3-4 meters and an arm length of 0.8 meters.

The width of the weld is less than 20mm, the remaining height of the fillet is 1.5mm~2.5mm, the fillet height of the fillet weld should be 6mm~8mm, and the size of the fillet is not allowed to be smaller than the planned size.
2. Hot-dip galvanizing is used for the anti-corrosion treatment. Before the anti-corrosion treatment, the steel components should be effectively derusted. The thickness of the hot-dip galvanizing should not be less than 85um, and the zinc layer should be uniform. When copper sulfate solution is used for the etching test, more than 4 times No iron is exposed. The zinc layer should be firmly combined with the metal body. After the hammering test, the zinc layer will not peel off and not bulge. Passivation treatment should be carried out after zinc immersion, and the 48h salt spray test is qualified. For every 100 m pole, the straight line measuring the axis, the full length of the pole and the steel cage of the base should be temporarily fixed to ensure that the plane of the base and top of the steel bar is level, that is, use a level ruler to measure in both directions of the base and top. The air bubbles must be centered; the concrete pouring and ramming of the embedded parts of the monitoring pole must be compacted to prevent the concrete from hollowing;
2. During construction, the pre-embedded pipe mouth should be sealed with plastic paper or other materials in advance to prevent the concrete from leaking into the pre-embedded pipe when the concrete is poured, causing the pre-embedded pipe to be blocked; after the foundation is poured, the root bottom must be high 5mm~10mm above the ground level; the concrete needs to be maintained for a period of time to ensure that the concrete can reach a certain equipment strength.

The top spot with a high-quality main pole. Generally better street lamp monitoring poles are main poles made of high-quality seamless steel pipes. Such a main rod can have a stronger ability to resist pressure. Therefore, when you buy the monitor pole, you must check the manufacturing information of the main pole of the monitor pole.
Second, it has a thicker wall. Generally, better monitoring rods have a thicker tube wall. Because of the thicker tube wall, the monitoring rod has better wind resistance and pressure bearing capabilities. So everyone must understand the thickness of the pipe wall when buying the monitor rod.
Third, it has the characteristics of convenient equipment. Generally better monitoring rods have the characteristics of sensitive equipment. As long as the operation is simpler than the general monitoring rod, it will have a better user experience, and then have a stronger competitiveness.

Choose rods reasonably to prevent the camera from being blocked in the selection of social security street lamp monitoring rods. According to different camera types, try to choose the height of the manuscript that meets the arrival monitoring function: height between 3.5-5.5 meters can be used as the selected height .

(1) Selection of the height of the gun-type camera pole: For the selection of the pole of the gun-type camera, try to choose a pole with a relatively low height, and generally choose a pole with a height of 3.5-4.5 meters.
(2) Selection of the height of the dome camera rod: the dome camera can rotate 360 degrees and the focal length is adjustable. All the rods selected for the dome camera should be as high as possible. Generally, we choose a rod between 4.5-5.5 meters Piece type. For the above-mentioned rods of various heights, a reasonable crossarm length should be selected according to the distance between the pole position and the monitoring policy direction and the viewing direction to prevent the crossarm from being too short to capture suitable monitoring content. In a sheltered environment, it is advisable to choose 1 meter or a cross arm 2 meters to reduce the shelter.
(2) In principle, the azimuth interval of the poles should not be less than 5 meters in the short distance of the monitoring target area, and the far distance should not be greater than 50 meters, so as to ensure that the monitoring screen can include more valuable information;
(3) Priority should be given to the use of light sources in places where there are light sources nearby. But pay attention to the orientation of the camera’s equipment should be in the direction of light;
① Open exposure compensation (the effect is not obvious); ② Use fill light; ③ Set the camera in the underground tunnel outside the entrance; ④ Set it in the channel.
(5) The position of the pole should try to avoid beautifying trees or other obstructing objects. If necessary equipment, consider avoiding the obstruction of trees or other obstructions, and leave space for the future growth of trees;
(6) Pay attention to the survey, try to get electricity from traffic police signals, street light distribution boxes, governments, larger enterprises, and institutions (such as government departments, public transport, water supply groups, hospitals, etc.) to facilitate harmony and progress The stability of electricity. Try to prevent small business users from getting electricity, especially for civilian use.
(7) The camera is on the side of the road. Pay attention to taking pictures of pedestrians in reverse, and the facial features of pedestrians on non-motorized vehicles. (8) The camera of the equipment at the bus station should be placed in the direction of the rear of the vehicle as far as possible, avoiding the headlights of the vehicle, so as to capture the people on the bus.

It is worth noting that, in the equipment standards for monitoring poles, it is required that the street light monitoring poles must have lightning rods and outstanding grounding maintenance, and can be led into the ground (it is recommended to conduct electricity without using poles), so to ensure the long-term normal operation of the front-end equipment , Surge maintainers matching various signal equipment are indispensable, and standard grounding is required.
The cameras are all mounted on a pole. If the soil condition on site is good (with less non-conductive materials such as rocks and sand), the pole can be directly grounded. The size of the pit is 2000×1000×600mm, and the bottom is fine or moist. The share of soil reached 85%. Fill it with fine soil, then bury a 1500mm×12mm steel bar straight, pour concrete, and when it reaches the ground, insert a fixing bolt (fixed according to the size of the pole base) with a bolt in between It can be welded with steel bars and used as a grounding electrode. After the concrete is completely stabilized, backfill with fine soil around it and ensure certain wetting. Finally, the ground wire of the camera and the lightning protection device can be directly welded to the ground electrode on the pole. Do a good job of anti-rust treatment, and mark the nameplate.
If the soil condition on the site is bad (there are more non-conductive materials such as rock and sand), you should use the data of adding the touch area of the grounding body. Use drag reducer, flat steel and angle steel, etc. Detailed measures: the previous operation is as above. Before pouring the concrete base, a chemical resistance reducing agent with a thickness of 150mm should be laid along the wall of the pit, with a 2500×50×50×3mm angle steel embedded in it, and 40×4 (iron) The flat steel is pulled down along the pole, the ground wire of the lightning arrester and the camera is properly welded to the flat steel, and the flat steel is welded to the underground angle steel (iron). The ground resistance test is less than 10 ohms according to the national standard.
The azimuth interval of the poles should not be less than 5 meters in the short distance of the monitoring target area, and the far distance should not be greater than 50 meters, so as to ensure that the monitoring screen can include more valuable information.
In places where there are light sources nearby, priority is given to using light sources. But pay attention to the orientation of the camera device should be in the light direction.
Try to prevent the equipment from being in a high-contrast area. If necessary, consider: ① Open exposure compensation (the effect is not obvious); ② Use fill light; ③ Set the underground camera outside the entrance; ④ Set it in the channel a little.
The pole position should try to avoid beautifying trees or other obstructing objects. If necessary, consider avoiding trees or other obstructions, and leave room for the future growth of trees.
Pay attention to the survey, try to get electricity from traffic police signals, street light distribution boxes, governments, larger enterprises, institutions (such as government departments, public transport, water supply groups, hospitals, etc.) to facilitate harmony and improve electricity use. Stability. Try to prevent small business users from getting electricity, especially for civilian use.
The camera is on the side of the road. Pay attention to reverse photographs of pedestrians, and the facial features of pedestrians on non-motorized vehicles.
The camera of the equipment at the bus station should be placed as far as possible in the direction of the rear of the vehicle, avoiding the headlights of the vehicle, so as to capture the people on the bus.

A reasonable length of the cross arm should be selected according to the distance between the pole position and the direction of the monitoring policy and the viewing direction to prevent the cross arm from being too short to capture suitable monitoring content.

Maybe something has been with you for a long time and you don`t even feel its existence. We take it for granted that it`s only there until one day it can`t work again. We won`t think it`s important.
Street lights, is such an existence, have the little friends encountered street lights maintenance?
That night without street lights
Must be unpleasant
Because Fengyun some time ago
Riding a bicycle without street lights and falling over
Without street lights, the driving partners will not have much impact. After all, there are still lights to keep lighting, but for others, everything seems to be less friendly. You must know that a lot of reflective materials are used on the bicycle. To reflect other light sources to make it visible to others, similar to this is the reflective guardrails on both sides of the roadbed, and some special groups of work clothes, police, security guards, sanitation workers, etc., if there are no street lights It is difficult to be seen easily by others, which is tantamount to increasing the risk factor of night roads.
It can be seen that urban lighting equipment
For our production and life
Is already an essential part
Fire is an important step in the history of human development
The use of fire is a milestone in progress
Bonfire lit by ancient people
Is the earliest lighting
Until the 15th century England
Only started to have dedicated streets
Street lamp for lighting

It is said that the first street lamp in the world appeared in Hyde Park in the United Kingdom to prevent bad citizens from committing crimes at night, not to facilitate people`s lives. It was not until the end of the 17th century that William III moved the palace to Kensington Palace. He found that night It is very dangerous to walk to St. James’s Palace by yourself. 300 oil lamps were installed on the road, which became the earliest artificial street lamp in Britain. This road has also become the notorious “Road of Kings”.

The Solar Street Light controller is an important part of the solar street light. It has serial communication data transmission function, manages the charging and discharging of solar street lights and remote intelligent control, and can control the time when solar street lights turn on and off. But many people do not know how to control the time of solar street lights when using solar controllers. The technician Wang from the solar street light manufacturer below tells everyone this principle. .
The solar street light controller can control the two things: the time when the street light is turned on and the duration of keeping the light on. Usually, the solar street light controller does not have a built-in clock, and it does not have a built-in clock. The lighting time is usually triggered by monitoring the current value generated by the Solar Panel. The current value is usually set to 5ma. Using the solar panel’s use time, you can adjust this value accordingly. The new solar street light controller supports multi-time adjustment and control. The lighting power of LED Lamps can be set in different time periods and should be adjusted according to actual needs.
The adjustment time of each solar street light controller is different. It has an infrared interface, a dedicated data line, and can adjust the network through the network. The best solution is to let the supplier help you before leaving the factory. Complete the operation. Generally, the solar street light controller does not have a built-in clock, and it usually does not operate according to the clock. The lighting time is usually triggered by monitoring the current value generated by the solar panel. The current value is usually set to 5ma. Using the solar panel’s use time, you can adjust this value accordingly. The new solar street light controller supports multi-time control. The lighting power of led lamps can be set in different time periods and should be adjusted according to actual needs.

The above is the working principle of the solar street light controller. In addition, if we want to better control the solar street light, we must understand the correct solar street light configuration and reasonable controller lighting time.

With the improvement of LED luminous efficiency and lifespan, coupled with the advantages of power saving, energy saving and environmental protection, the feasibility of LED to replace traditional lighting in the application of street lamps is greatly improved. Compared with traditional lighting sources, LEDs provide better lighting capabilities in terms of light source dispersion and energy saving, and at the same time change the general industry’s perception of the use of high-quality light sources, and are also applied to streets and general roads. Current streets use high-pressure sodium lamps for lighting, and some use metal halide, low-pressure sodium lamps or other types for lighting. The use of high-pressure sodium lamps is due to their longer service life and higher efficiency compared to other traditional lamps, but they are less selective in the provision of colors. LEDs have a longer service life and lower maintenance than high-pressure sodium lamps Cost, a variety of colors available, low energy consumption and cost savings. However, the initial cost of using LEDs is still higher than that of commonly used light sources.
Professional LED street lamp manufacturers introduced that under the rapid growth of LED technology and continuous improvement of product characteristics, LED street lamp demonstration plans were launched in various countries. Through the evaluation and analysis of LED street lamp demonstration plans, it can provide governments and LED manufacturers in the future street lamp market. Put it into application as a demonstration plan.
The LED street lamp demonstration plan is to replace the original 121 watt high pressure sodium lamp with 15 78 watt LED lights on 3 roads. For comparison and comparison, a brand new high pressure sodium lamp is installed on the east side of a road and LED on the west side. Street lights; LED Street Lights are installed on one road, and new high-pressure sodium lights are installed on another adjacent road. All lamps are installed 28.5 feet above the road, with a pole distance of 110, 120 or 160 feet.
The test results found that the average power used by each LED street lamp is 77.7 watts, which saves about 35% of the power compared to the average power of the high pressure sodium lamp HPS of 121 watts. Based on the 4100 hours of operation time per year, it is expected to save a year. Under 178 kilowatt hours.

According to the measurement results, it can be known that, on the whole, the illuminance of the LED lamp is the same level as that of the high pressure sodium lamp or higher than that of the higher pressure sodium lamp. In addition, because the LED lamp directly measures the illuminance directly under the fixing device and is slightly darker than the high-pressure sodium lamp, the uniformity of the LED lamp is relatively good. In low light conditions, compared to high-pressure sodium lamps, the illuminance of LED street lights can be maintained at the same illuminance level and increased.

With the rapid development of solar photovoltaic power generation technology, solar street lights have quickly been promoted and applied in cities and rural areas, especially in rural areas where there is no power grid, and have achieved success. At the same time, many electricity has been installed Solar street lights have also begun to be installed on the urban roads of the route, but these roads are different from rural roads. If they are designed in the same way, on the one hand, they cannot meet the requirements of urban road lighting, and on the other hand, they will waste resources. Therefore, the utility power complementary solar street lamp can solve this situation well. The utility power complementary solar Led Street Light is composed of solar panels, Solar Street Light controllers, batteries, lighting fixtures, consoles and power communication lines. Its advantages are very obvious. The following editor will introduce to you what its advantages are:

1. It can greatly reduce the cost of dual power supply for street lights in urban areas, reduce energy consumption, and conform to the concept of green and environmental protection.
2. Turn on the lights 365 days a year. Normal solar street lights are generally unable to keep on for multiple rainy days because of battery capacity and battery panel power design issues. The complementary solar LED street light from the mains can be automatically switched to the power source during rainy days, ensuring that the lights are on every day for 365 days.
3. Improve the service life of solar batteries. Complementary solar street lights with commercial power can reduce the number of cycles of solar batteries to a limited extent, which will inevitably increase the service life of batteries.
4. There is no need to arrange additional communication lines, and the cost is low, the communication error rate is low, it is not easy to be interfered, and large-scale networking control can be carried out.

The above are the advantages of complementary solar street lights. When we use it, we must adapt to local conditions, use it reasonably, and match it properly in order to achieve its good lighting effect.
