Led Traffic Lights
Basic Information:
LED traffic lights are light and color signals that are alternately replaced at a specified time. They are usually installed at intersections or other special places to assign roadway rights to vehicle drivers and pedestrians, and to control traffic control facilities for stopping and turning. . Located at a fork in the road or other necessary places. Signal lights are an important part of traffic signal command and the basic language of road traffic. Traffic lights are composed of red lights (indicating no traffic), green lights (indicating traffic allowed), and yellow lights (indicating warning). Divided into: motor vehicle signal light, non-motor vehicle signal light, crosswalk signal light, lane signal light, direction indicator light, flashing warning light, road and railway intersection signal light. It is widely used in highway intersections, bends, bridges and other dangerous sections with hidden safety hazards, to direct drivers or pedestrians to traffic, promote smooth traffic, and avoid traffic accidents and accidents.
Function classification:

Traffic control lights use circular red, yellow, and green lights and arrow patterns to assign the right of way for traffic in different directions in a time-changing manner; or by circular lights containing only red and green, To control traffic in one-way wheels. It is generally located at a fork in the road or on a road with one-way wheel release control. According to the operation mode:
Timing signal lights, traffic sensor lights, traffic adjustment lights, pedestrian traffic lights are used in conjunction with traffic control lights, with square red and green lights with patterns of “standing pedestrians” and “walking pedestrians” to control pedestrians crossing the street. A fork in the road or the middle of the road. According to the operation mode:

Pedestrian touch signals with timing signals Special traffic signals include: Lane control signal lights are square red and green lights with cross-shaped and arrow patterns. The right to use the lanes is allocated and located in the middle of the road or toll stations. Four-signal time-phase signal lights at multi-temporal intersections (installed at T-shaped and Y-shaped intersections and intersections where left, right, and no entry are prohibited, the time for vehicles to turn left will be restricted). Multi-temporal intersections with five-signal time-phase signal lights (set at intersections from three lanes to four lanes, red, yellow, left-turn green arrows, forward green arrows, right-turn green arrows, etc., five lights to control the movement of vehicles Stop, in addition, the fixed left turn time of this signal light is set to red light and green arrow to turn left to allow vehicles to turn left). Railway level crossing signal lights are parallel circular double flashing red lights, which prohibit pedestrians and vehicles from crossing the railway level crossing, and are set in front of the railway level crossing. The crosswalk signal light is a parallel double-flashing yellow light signal to warn that approaching vehicles should slow down. If there are pedestrians, they must pause to allow pedestrians to cross the street first. They are set in front of the zebra pattern pedestrian crossing marking. Special flashing lights are flashing red or yellow lights on a single mirror to warn approaching vehicles to pay attention to the road conditions ahead. They should stop or slow down first, and then stop at a fixed speed depending on the road conditions. They are set in front of forks or dangerous roads. Blind audio signal lights are set up with dedicated pedestrian signal lights or crosswalk signal lights with fixed audio sources to inform the blind of the direction in which the blind can pass and warn the vehicle driver that the blind is passing. If necessary, set at a fork in the road or a section of the road near the place where the blind travels are concentrated. The ramp instrument control signal lights use circular red, yellow, and green lights or the alternation of red and green lights to control the movement of vehicles on the on-ramp to restrict vehicles from entering the main line of the expressway. At the location where the entrance ramp connects with the acceleration lane. Its operation mode can be timing signal light or traffic adjustment signal light.

Signal light source:
LED (Light Emitting Diode) is a new type of light source developed and produced in recent years. It has low power consumption (current only 10-20mA), high brightness (light intensity up to tens of thousands of mcd), and small size (the smallest diameter can reach 3mm) , Light weight (a light-emitting diode weighs only a few ten grams), long life (average life span of 100,000 hours) and other advantages.

Solar lighting will become the new target of the lighting industry. Solar lighting is an application of photoelectric conversion technology and a representative of the new energy industry. It has the benefits of energy saving, environmental protection, safety, no wiring, sophisticated installation, intelligent control, and the ability to change the location as needed. In cities with energy shortages, power cuts, and remote areas where electricity is difficult, it has a strong scalability. The solar power lighting system currently used is developed in accordance with China’s national conditions and people’s conditions, and the price is relatively high. The main types of solar lamps are solar street lights, Solar Garden Lights, solar lawn lights, solar landscape lights, and solar signal lights.

It is especially suitable for installation in remote areas such as Gobi, mountainous areas, grasslands, etc. that are inconvenient to connect to city electricity, such as Yunnan, Gansu, Xinjiang, Tibet, Inner Mongolia and other places. As an infinite renewable energy source, solar energy is the most ideal new energy source for mankind. In the future, it is a general trend to gradually replace the conventional energy produced and live in cities.

Due to the inexhaustible rise in the prices of international conventional energy coal and oil, domestic energy supply is tight, many cities are presenting an environment of power cuts, and the development of alternative new energy has risen to the height of national energy strategy security. Many road lighting began to consider using solar street lights, solar street lights are also the first choice for lighting products in the new countryside. From a long-term perspective, the prospects of the solar lighting industry are very good. In recent years, the state has issued a series of favorable policies to support the growth of renewable energy, including the “Renewable Energy Promotion Law” and the “Plan for Sustainable Growth in Renewable Energy” that were implemented in 2006.

People’s consumption focus is first of all practicality, low cost, long life, environmental protection and safety. As one of the most important operating methods of solar energy, solar lighting has also attracted more and more attention from the new energy industry and the lighting industry. Currently, there are more than tens of thousands of domestic Solar Street Light manufacturers, most of which are concentrated in Shenzhen, Zhongshan, Yangzhou, Changzhou, Linyi, Shanghai, Wuxi, Zhejiang and other places. At present, China’s solar lighting technology has matured, and the reliability of solar lighting has been greatly improved. The solar lighting of advanced enterprises in the industry has reached or even exceeded the national lighting standard.

From the current point of view, solar power lighting technology is the only mature technology that can be quickly applied on a national scale. This series of benefits is an encouragement and support for the solar industry. China has already successfully promoted the model for reference, and the conditions for large-scale promotion of solar lighting lamps in China are ripe.

Nowadays, solar energy has become a recognized clean and green energy, and it is gradually applied to people’s livelihood to benefit mankind. Among them, solar street lights are one of the solar energy applications.
The Solar Street Light system consists of solar panels, controllers, storage batteries or lithium batteries, lamps, light poles, cables and other parts.

What is the future of solar street lights? The answer is yes. From the perspective of economic benefits, according to calculations, based on the calculation of 5m street lights and 8m street lights, after adopting solar street lights, 5m street lights and 8m street lights save about 2,290 kilowatt-hours of electricity each year, and the electricity bill saves 1,633 yuan. It has a good profit margin. From the perspective of energy saving and environmental protection, its electricity comes from solar power generation, which does not consume traditional energy, and is energy-saving and environmentally friendly. In the future, the solar street lamp industry will receive support and promotion from many parties due to its obvious social and economic benefits. The market scale of solar street lamps may show a rapid growth trend.

When many customers first come into contact with solar street lamps, they always like to search the Internet for solar street lamp manufacturers and their rankings.
Since 2005, although solar street lights have been used more and more, especially in the vast rural areas, there are still many shortcomings, so far no large-scale production has been used, so many manufacturers are not For stocking, customers usually place orders, and produce according to customer requirements.

According to the types of lamps used in road lighting design and the height of the poles, road lighting poles can be divided into three categories: conventional poles, medium poles, and high poles. Conventional light poles can be divided into wooden poles, reinforced concrete poles, steel poles and glass fiber reinforced plastic poles according to the material. The poles for medium and high pole lighting are mainly made of steel. The decorative courtyard lamps are summarized and casted by aluminum alloy lamps. Aluminum or cast iron poles, ceramic poles, etc. The lamp arm (frame) on the top of the pole has forms such as single pick, double pick and dobby. The most widely used road lighting is the steel pole, which has the advantages of beautiful, strong and durable. This chapter mainly introduces steel poles.

1. Steel poles can be divided into equal-diameter poles, cones, and polygonal cones. The common typical cross-sectional shapes are hexagons, octagons, and circles. Usually, the whole steel plate is cut and formed by folding at one time. The light pole taper ratio is generally 10‰~12.5‰, using high-quality steel plate such as Q235 type, and the wall thickness is ≥3.5 or 4.0mm. The advantages of the tapered steel pole are reasonable structure, novel and beautiful appearance, and convenient construction and installation.

2. The installation methods of steel poles are divided into three types: direct-buried, flanged and tiltable. The direct-buried type is simple to install. The entire light pole is directly buried in the earth pit, returned to the soil and tamped or fixed by concrete pouring on site. The disadvantage is that the light pole must be re-poured for maintenance and updating. The flange-type light pole is connected by the bottom flange of the light pole and the prefabricated reinforced concrete foundation foot bolts. The installation is extremely simple, and the replacement of the light pole does not need to redo the foundation. This is currently the most widely used installation method. Due to the limited installation environment of the light pole or the lack of corresponding maintenance equipment, the tilting light pole can be selected. The existing tilting light poles mostly use mechanical and hydraulic systems, which are easy to operate and safe, but the one-time investment is relatively high. Commonly used cone light pole design data can be found in the “Urban Lighting Project Construction Manual” published by China Electric Power Press.

3. Directly buried steel poles, the allowable deviation of its length (including the buried part) is ±0.5% of the pole length.

4. Flange-type steel lamp pole, the allowable deviation of its length is ±0.5% of the pole length.

5. The allowable deviation of the cross-sectional dimension of the light pole shaft is ±0.5%

6. The size of the maintenance operation door and frame is allowed to be ±5mm according to the design requirements. The door locks and hinges are flexible and have anti-theft functions.

7. The steel pole should be hot-dip galvanized, and the thickness of the galvanized layer should not be less than 65μm. The surface painting and plastic spraying treatment should be performed after hot-dip galvanizing the pole, and the parts modified due to straightening and other factors should not exceed 2 locations, and the trim area must not exceed 5% of the shaft surface area.

8. Light poles and light arms (frames) are hot-dip galvanized and then painted and coated. Their appearance, adhesion, and heat resistance should be checked and accepted according to the current standard QB1551-P2 “Lamp Paint Coating”.

9. The lamp poles and lamp arms (frames) are sprayed, and the covering layer should be free of defects such as bulges, pinholes, roughness, cracks or missing spray areas, and the covering layer and the lamp pole substrate should have a firm bonding strength.

1. The fixing strength of the ground cage is too small, which makes the installation of the lamp unstable.
Reason analysis: there is no professional foundation designer; the quality of the ground cage production personnel is not strict; the ground cage is cut corners and shoddy.
How to avoid: Professional lighting designers to ensure design quality, high-quality production personnel plus quality control internal inspections, strictly control the quality of the cage welding. From raw material quality control to finished product quality inspection, to ensure that the product meets the requirements.
2. The foundation structure design is unreasonable, causing the battery to soak.
Reason analysis: There is no professional designer to carry out reasonable foundation design, and the on-site construction personnel have poor ability to control the site and cannot adjust the foundation position according to the actual situation.
How to avoid: Excellent professional designers carry out foundation structure design based on actual investigations, and qualified on-site construction teams can carry out reasonable construction based on on-site factors.
3. There is no insulation measures in the battery compartment, and the battery capacity decreases.
Reason analysis: The designer has no concept of battery insulation, and the construction staff is not high in professional quality, and cannot be constructed in full accordance with the technical requirements.
How to avoid: Excellent designers can carry out special treatment according to local climate conditions, and professional construction teams strictly follow standardized operating procedures for construction.
Also need:
4. A qualified installation and construction team ensures that problems in the installation process are discovered in time and can propose solutions.
5. Professional designers must keep abreast of the site conditions in time, and site inspections when necessary to ensure the rational design of the lighting system.

In recent years, solar street lights have been at a peak. As the industry gradually matures, more and more solar street lights are in competition. In order to meet the needs of the new situation and new environment, street lamp manufacturers have developed and produced various forms based on the principle of harmony and unity of lighting and environment, and organic combination of lighting and beautification. As the price drops, the development of lights has also improved. So what is the difference between Solar Street Light cleaning and ordinary street light? Let`s take a look at how to clean solar street lights.

First, the ground cage
After the solar street light is installed on the ground, people still need to reinforce it. The street light is originally made of extremely strong stainless steel, so its surface will not be damaged by wind and sun. However, after considering the wiring problem, if the user wants to ensure that the solar street light circuit will not be damaged due to long-term use, the ground cage used to fix the street light must be treated rigorously. The skeleton made of stainless steel is wrapped around the foundation (foundation) of the solar street light, so as to ensure that the use of the solar street light can maintain the most stable state.

Second, the battery
The reason why the battery is taken into consideration is very simple. As a lighting facility that can absorb solar radiation autonomously, in the cloudy and rainy season, it undoubtedly cannot rely on the absorption of radiation to meet the lighting needs, so solar street lights also have a demand for batteries That’s why. When considering the use and purchase of basic components of solar street lights, the power supply capacity and continuous battery life that the street light battery can play (showing its inherent ability) need to be considered.

Although solar street lights have been developing, the cleaning problem still cannot be ignored. Solar street lamp manufacturers have a series of road and square landscape lighting products with great aesthetic and ornamental value, so as to seize the opportunity and expand the market. If the design of the Solar Garden Light is reasonable, it does not matter if the street light can face the cloudy sky for five consecutive days after the sun shines. Because it is different from traditional ordinary street lights, the cleaning process is also more complicated. Once you are not paying attention, it is easier to cause damage. Of course, it is particularly important to choose manufacturers with guaranteed quality.

The above is an introduction on how to clean solar street lights. If you have other questions, you can directly call our company hotline. Solar Garden Lights LED has high luminous efficiency, and its luminous efficiency is much higher than energy-saving lamps, metal halide lamps and induction lamps, and 10% higher than high-pressure sodium lamps commonly used in street lighting. Solar street light manufacturers have always adhered to the tenet of “Quality is the life of the enterprise”, based on the corporate philosophy of “We will do better”, so as to make contributions to the cause of urban road lighting. We will serve you wholeheartedly.

What is the difference between solar power generation, off-grid and grid-connected:
Off-grid system means that the electricity generated by the photovoltaic power generation system is stored in the battery and converted into AC power through the inverter for direct use by the electrical equipment, or directly supplied to the DC electrical equipment without inverter, and is not connected to the grid .
Grid-connected means that photovoltaic power generation is converted to AC through an inverter, and connected to the grid through a boost or direct low-voltage side, and the grid dispatches and uses the electric energy.
What is the principle of photovoltaic off-grid power generation system:
The working principle of off-grid photovoltaic power generation system is very similar to that of grid-connected photovoltaic power generation system. The only difference is that the power output from the off-grid system is directly consumed and used instead of being transmitted to the public grid. Solar power generation, thermal power generation and photovoltaic power generation. Regardless of production and sales, development speed and development prospects, CSP can not catch up with photovoltaic power generation. It may be that photovoltaic power generation is more popular and there is less exposure to CSP. Generally speaking, solar power generation often refers to solar photovoltaic power generation. Photovoltaic power generation is based on the principle of photovoltaics. Solar cells are used to directly convert solar energy into electrical energy. Whether it is used independently or connected to the grid, the photovoltaic power generation system is mainly composed of solar panels (components). Controller and inverter three Most of the components. They are mainly composed of electronic components. No mechanical parts are involved. Therefore, photovoltaic power generation equipment is extremely refined. Reliable, stable and long life. Installation and maintenance are simple. In theory, photovoltaic power generation technology can be used for any occasion where power is required. Up to spacecraft. Down to household power supplies. As large as megawatt power stations. As small as toys. Photovoltaic power supplies can be ubiquitous. At present, photovoltaic power generation products are mainly used in three aspects: one is to provide power for non-electricity occasions. Mainly Provide electricity for the life and production of residents in the vast areas without electricity. There are microwave relay power supplies, etc. In addition. It also includes some mobile power supplies and backup power supplies, and the second is solar daily electronic products. Such as various solar chargers, solar street lights and solar lawns. The third is grid-connected power generation. This has been widely promoted in developed countries. China`s grid-connected power generation has not yet started. However, in 2008 Beijing [Green Olympics” part of the electricity will be solar power and wind power Power generation provision.

The most basic component of solar photovoltaic power generation is solar cells (sheets). There are monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin-film batteries. At present, monocrystalline and polycrystalline cells are used the most. Amorphous cells are used in some small systems and calculations. The efficiency of domestic crystalline silicon cells is about 10-13%. The efficiency of similar foreign products is about 12-14%. Solar panels composed of one or more solar cells are called photovoltaic modules. In 2002, global solar cells The output of photovoltaic modules is about 600MW. Japan accounts for 45%. The United States 25%. Europe is about 22%. Japan is the fastest growing factor in the photovoltaic industry. In less than 10 years, it surpassed the United States. In 2001, the top 10 in the world There are 4 solar cell manufacturing plants in Japan. They are Sharp. Kyoto Ceramics. Sanyo and Mitsubishi. Most developed countries in Europe and the United States have formulated the “Sunshine Plan”. Measures have been taken to encourage residents to install solar power generation systems. For example, partial grants. Interest-free Loans and [seed funds”, etc., and purchase surplus solar power in residents` homes at a price several times higher than the ordinary electricity price.

China’s solar photovoltaic power generation industry has developed rapidly in recent years. But the overall scale is small. In 2002, the output of solar cells was about SMW. The cumulative installed capacity reached 25MW. Less than 1% of the world. In order to cooperate with the western development, the Chinese government implemented the [ “Sunshine Project”. [Chengfeng Project” and [Bright Project”, etc.. Use solar power and wind power to solve the electricity consumption of farmers and herdsmen in the vast western regions without electricity. The supporting funds of this project are more than 2 billion yuan. China’s photovoltaic power generation The product market is mainly in the west. There are also some products coming out of the day. Such as modules, small systems and daily-use solar electronic products. Because the domestic solar cell wafer output is far from meeting the demand. Many manufacturers import a large number of solar cell packaging modules. In terms of photovoltaic industry. Shenzhen occupies part of the country. Product processing capacity. Product quality and sales have a certain impact at home and abroad. The government should increase support. Make it expand and develop into an industrial cluster. And then become an economic growth point for Shenzhen .

The solar photovoltaic power generation industry is growing rapidly. It is not only because it is a clean energy with many advantages. A more attractive motivation is. In the process of integration of solar energy and buildings. Solar cell modules are more compatible with buildings than solar water heaters. The sun. Battery modules can not only be used as energy equipment. They can also be used as roofing and wall materials. It not only saves power and saves building materials. There are already very good cases abroad. Therefore, the combination of solar photovoltaic power generation technology and construction will have a good economy. Benefits. The future is unlimited.

The global energy crisis, but inexhaustible free solar development and application has been widely recognized by the international community. Moreover, my country is also a big energy country, and under the support of policies, photovoltaic power generation is gestating huge business opportunities.

The Fifth Plenary Session of the 16th Central Committee of the Communist Party of China began to accelerate the “New Countryside Construction”. At present, my country’s solar new energy utilization market accounts for less than 10% of sales, which is far below the 50% of the international market. Solar power generation will become the dominant energy source in rural areas in the future and become an explosive growth. The best time for photovoltaic power generation has arrived.

Considering from the starting point of being a start-up, it must be energy-saving benefits. In today’s society, low-carbon and environmental protection has become a global consensus. Our country is also advancing with the times and vigorously promoting energy-saving and emission-reduction policies, so energy-saving has become an important part of development. issue. Maximizing energy saving is the ultimate goal of all mechanized products. The solar street lights are in line with this development trend and are leading the way. No matter what kind of product, as long as it circulates in the market, it can prove the value of its existence. This means that existence is reasonable. Maybe it does not receive many people, or its function has not been widely recognized, but since it has embarked on this path, it can at least explain one thing that at least this is a dream of the founder, at least he will think that such a contribution is It is worthwhile, even if such a product did not create any economic benefits for him. From the first day when solar street lights came out, perhaps no one has been optimistic about it, but practice has proved that it is still very courageous.
With the advancement of the construction of a new countryside, solar street lights are in a stage of rapid development, and manufacturers have sprung up like bamboo shoots after a rain. They are all taking a fancy to this market, but despite this, there is still a lot of room for development. Solar street lamp light distribution technology needs to be improved, and this industry revolution has just begun!

In terms of working principle, solar street lights use solar energy as the light source, and solar panels charge the battery during the day. At night, when lighting is needed, the battery will start to power the light source. In use, it does not need to lay complicated and expensive power supply lines, so that it can be installed in any site and any environment. Its battery adopts natural light and can be recycled. It does not need external power supply. The source is green and environmentally friendly. When the sun is insufficient to a certain extent, solar street lights It can automatically adjust the switch, truly unattended, all-weather work.

Compared with traditional incandescent street lamps with high voltage power supply, solar street lights are very different in product characteristics, material structure and power supply lines. Solar Street Light is a kind of traffic and road condition lighting that our country uses solar energy as the external power supply energy for street lights. Street lights play a very important role in urban life and are our eyes for travel and nightlife.

In terms of product features, solar street lights use solar energy in their light sources. During the day, it can use the solar circuit board to charge the battery in the street lamp, and at night, the battery can supply power to the lamp, which can fully meet the needs of lighting. The solar power used by solar street lights is green and environmentally friendly, and it can be seen everywhere in nature, which saves the materials needed for laying power lines, saves a lot of manpower and material resources, and improves construction efficiency. In addition, solar street lights are green, environmentally friendly, energy-saving, long-life, stable product structure, and have very good social and economic benefits.

Solar street lights, use environmental conditions: 1. Altitude: ≤5000M; 2. Ambient temperature: -50℃_+70℃; 3. Design wind speed: 35m/s; 4. Relative humidity: 80%; 5. Seismic intensity : Level 8

Street light pole manufacturers solar street lights do not need to lay underground cables, and do not need to pay for lighting electricity. The key components used in solar LED Street Lights, solar panels, solar DC street light intelligent controllers, maintenance-free batteries, and lighting lamps have all passed national product certification. Solar LED street lights are mainly suitable for the lighting of roads, squares, parks, tourist attractions, green belts and other places.

LED cold light source, compared with incandescent lamp, energy saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of the ordinary incandescent lamp, 1/3 of the fluorescent tube, 1/2 of the low-voltage energy-saving lamp, and the LED light source is recognized as a light source for solar systems*. The LED adopts fine control mode, and the LED light is in Working in this mode can significantly reduce the heat of the LED lamp, and effectively solve the problem of dead beads and light decay of the LED lamp.

Solar LED street lights of street light pole manufacturers usually use crystalline silicon solar cell components, which have excellent low light response performance and need to comply with electrical related specifications. Anti-reflection film and high transparency glass greatly increase the energy generated; 4-6 holes are opened on the frame, which is easy to install on all system structures; standard MC connectors and 1m long cables are provided; there are 3 in the junction box The diode greatly reduces the system power loss shielded from the component.

The street lamp battery of street lamp pole manufacturers adopts lead-acid maintenance-free or gel battery, which has the advantages of small size, light weight, low self-discharge, low maintenance, long life, convenient use, no corrosion to the environment, and no pollution. Compared with batteries, it has obvious advantages in use, maintenance and management

As the demand for street lighting becomes more and more prosperous, the market for its supporting products street lamp poles is also growing. But did you know? In fact, there are different classifications of street lamp poles, and the materials used for street lamp poles are also different. Some street light poles are sold overseas, and some are gradually withdrawn from the market. Let me talk about street light poles.
Street light pole classification, what are the street light pole materials?
1, cement street lamp pole
Cement street light poles are attached to urban power poles or cement poles are erected separately, because they are bulky, costly in transportation, and relatively dangerous. Now the market has gradually phased out such poles.
2, iron street light pole
Iron street lamp pole, also known as high-quality Q235 steel pole. It is made of high-quality Q235 steel, hot-dip galvanized and sprayed with plastic. It will not rust for 30 years and is very hard. This is the most common and used street light pole in the street light market.
3, fiberglass street light pole
FRP pole is a kind of inorganic non-metallic materials with excellent performance. There are many kinds of them. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. Therefore, not many are used in the market.
4, aluminum alloy street light pole
Aluminum alloy street light poles are made of high-strength aluminum alloy. The manufacturer not only protects the safety of personnel in a humane manner, but also has high strength, does not require any surface treatment, has corrosion resistance for more than 50 years, and is very beautiful. It looks more upscale. Aluminum alloy has better physical and mechanical properties than pure aluminum: easy processing, high durability, wide application range, good decorative effect, rich colors and so on. Most of the street light poles are sold overseas, especially in developed countries.
5. Stainless steel street light pole
Stainless steel pole has the best chemical and electrochemical corrosion resistance in steel, second only to titanium alloy. The method adopted in our country is to conduct hot-dip galvanizing surface treatment, and the life of hot-dip galvanizing products that meet international standards can reach 15 years. Otherwise it is far from reach. Mostly used in courtyards, communities, parks and other places. Heat resistance, high temperature resistance, low temperature resistance and even ultra-low temperature resistance.

Because the quality of the pole material of the street light will directly affect the service life of the pole. Therefore, it is recommended: When choosing a street light pole, you must pay attention to whether the material is suitable. The core components of our company`s solar lighting are completely self-produced. The pole is one of them. We are strict, responsible and attentive to the product, and we will definitely let you use it. Don’t worry, use it comfortably.

In today`s society, urban construction is developing faster and faster, and road construction is in full swing! Roads are an important part of our current urban civilized transportation system, which is important for traffic management, avoiding traffic accidents, and improving road use efficiency. The current situation of urban traffic is of great significance. As an important part of the traffic signal pole shell, it plays a very important role in the protection and safe use of traffic signal lights! If there is no shell, there is no normal and safe use!

There are several requirements for the safety of the shell of the road traffic signal pole:
1. Creepage distance and electrical clearance requirements
The creepage distance and electrical clearance between various live parts in the shell and adjacent metal parts shall not be less than 3.6mm.
2. Specific regulations for wire fixing frame and terminal

At present, solar LED Street Lights have a variety of models and specifications in the market, which can well meet various needs of users.
In order to ensure the efficiency of solar Led Street Light lighting, merchants must clarify the product model of LED Solar Street Light when purchasing, which can facilitate future maintenance work. Products after repair should be reported to the manufacturer`s engineers in time. This type of failure can be effectively avoided in the solar LED street lights produced in the future.
This also creates very good conditions for its future sustainable workability, which can effectively increase the working characteristics of its products to a certain extent, so that solar LED street lights can be more durable. When installing solar LED street lights, only guarantee LED The high efficiency of solar street lights can ensure the road to achieve good road lighting.
Solar LED street lights are now more and more widely used in road energy-saving lighting. Because LED solar street lights are durable and energy-saving, they are relied on by government agencies or large enterprises in various countries, and LED solar street lights are used by street light manufacturers to reduce energy consumption. At the same time, the quality of road lighting is improved to ensure people’s travel safety.
The working principle of the solar street lamp is very simple, that is, the Solar Panel made by the photovoltaic special effect principle receives solar radiation energy during the day and converts it into electrical energy output. It is stored in the solar battery through the charge and discharge controller, and the illumination gradually decreases to About 101ux, the open circuit voltage of the solar panel is about 4.5v. After the charge and discharge controller measures this voltage, the solar battery discharges the lamp holder.
Generally, the market price of solar battery discharge can be set by yourself or controlled by light. The main function of the charge and discharge controller is to protect the battery and control the switching of solar street lights. Therefore, the use of solar controller and solar battery is important for photovoltaic power generation solar street lights. It was a very important component system.
The price of LED street lights is expensive because its LED light source is generally epoxy resin, which has the function of anti-ultraviolet and fire retardant. The price of high-quality outdoor LED street lights will naturally have an impact. Every product of street lamp manufacturers has In different designs, different designs can be used for different purposes, so that it has a certain versatility.
In terms of energy saving and health, it may also be the reason for the high price of LED street lights. It is designed with non-toxic materials and does not contain the presence of lead, mercury, cadmium lamp toxins, giving the use of environmental safety and reliable protection. The advantages of dust and moisture-proof design, fire prevention, ultraviolet radiation, and low temperature cracking, have so many advantages, and the high price of such high-quality LED street lights is understandable.
Solar energy control is used in solar power generation systems. It can control the automatic equipment of solar battery charging and solar battery powering solar inverter loads. Generally, solar street lights use valve-regulated sealed lead-acid batteries, which is beneficial to system maintenance. The cost is reduced, and the charge and discharge controller is designed with both complete functions and cost control to achieve a good cost performance.
1. The stability of the solar controller is very important to the service life of the solar led street lamp, because the function of the solar controller is to control the use of the solar panel to charge and discharge the battery of the street lamp manufacturer. The solar controllers currently used are all The intelligent configuration used ensures that the street lights are illuminated and dimmed at the correct time, and the time will automatically change according to the changes in weather and environment.
2. When choosing a solar battery, you must choose a stable quality to ensure the service life of the battery. The quality of the battery can also directly affect the service life of the street lamp.
3. The lamp holders of solar street lamps generally include sodium lamps, induction lamps, led lamp holders, etc., but the service life of the led lamp holder is the longest, generally up to 50,000 hours, but its price is also more expensive than others.
Through the above three introductions, everyone should know the issues to pay attention to when buying solar street lights. Also, when buying solar street lights, don`t buy some low-priced, very likely low-priced street lights because they are expensive. The quality is not guaranteed. You must go to a large professional street lamp manufacturer to buy a lamp. Only a professional manufacturer can guarantee the service life of the street lamp and guarantee a certain after-sales service.

As the earth’s resources become increasingly scarce, the investment cost of basic energy is increasing, and various safety and pollution hazards are everywhere. Solar energy, as a kind of “inexhaustible and inexhaustible” safe and environmentally friendly new energy, is becoming more and more valued. At the same time, with the development and progress of solar photovoltaic technology, solar power generation has developed rapidly in the field of street lighting.
What is Solar Street Light?
Solar street lights are powered by crystalline silicon solar cells, batteries store electrical energy, ultra-bright LEDs are used as light sources, and are controlled by an intelligent charge and discharge controller to replace traditional public power lighting street lights.
The main components of solar street lights: solar panels, batteries, controllers, light sources, poles.
What is the working principle of solar street lights?
During the day: the Solar Panel absorbs the solar spectrum to generate electric energy, and is controlled and converted by the controller to store the electric power generated by the solar panel in the battery. At night: The electric energy in the battery is converted by the controller to drive the LED light source to emit light.
Solar street lights are composed of solar panels, batteries, controllers, light sources, light poles, etc. Next, I will introduce the core components of solar street lights.
Main composition-solar panel
Solar panel-also known as “solar chip” or “photocell” or “solar cell”, is a kind of photoelectric semiconductor sheet that uses sunlight to directly generate electricity. Solar cells are devices that directly convert light energy into electrical energy through photoelectric effect or photochemical effect. Polycrystalline silicon and monocrystalline silicon solar cells that work with the photoelectric effect are the mainstream. Sunlight shines on the semiconductor p-n junction to form new hole-electron pairs. Under the action of the electric field of the p-n junction, holes flow from the n zone to the p zone, and electrons flow from the p zone to the n zone, and the circuit is turned on to form a current.
Solar cell classification: monocrystalline silicon cell, polycrystalline silicon cell, amorphous silicon cell, thin film cell
Types of solar cells
The various types of solar cells are also very different, as follows:
Main components-battery
Store electrical energy as chemical energy, and convert chemical energy to electrical energy again when it needs to be discharged. This type of battery is called a storage battery.
Generally, there are lead-acid batteries, Ni-Cd batteries, Ni-H batteries, and lithium batteries. The selection of battery capacity generally follows the following principles: First, on the premise that it can meet the lighting at night, store the energy of the solar cell components during the day as much as possible, and at the same time, it must be able to store the electrical energy that can meet the lighting needs of continuous rainy days at night. The battery capacity is too small to meet the needs of night lighting, the battery is too large, the battery energy can not be used up, resulting in waste. The battery should match the solar battery and the electric load (street lamp). A simple method can be used to determine the relationship between them. The battery capacity is required to meet the total energy consumption in rainy and cloudy days, and the power of the solar panel meets the requirements for the battery to be fully charged under one day’s effective light conditions.
Performance comparison of different battery systems
Performance comparison of different Lithium Battery material systems
Main components-photovoltaic controller
Photovoltaic controller: an automatic control device that controls the solar panel to charge the battery and the battery to supply power to the load. Regardless of the size of the solar street lamp, a charge-discharge controller with good performance is indispensable. In order to extend the service life of the battery, its charging and discharging conditions must be restricted to prevent the battery from overcharging and deep discharge. In places with large temperature differences, qualified controllers should also have temperature compensation.
Features of photovoltaic controller:
1. Perfect protection function: over temperature, reverse connection, short circuit, over current, over charge/discharge, etc.
2. Power adjustment: automatically adjust the discharge power according to the daily charge
3. Historical data: can read historical data of 7 days of work
4. Status indication: indicate the current working status
5. Maximum efficiency tracking of solar panels
Main composition-LED light source
LED (Light Emitting Diode), a light-emitting diode, is a solid-state semiconductor device. The carriers in the semiconductor recombine and cause photon reflection to generate light. It has the advantages of high brightness, energy consumption, long life, fast start-up, low power, no flicker, and less visual fatigue.
SMD LED lamp beads classification
Features of LED lamp beads:
1. Small size, LED is basically a small chip encapsulated in epoxy resin, so it is very small and light.
2. Long service life, the theoretical service life is 100,000 hours, and the actual service life reaches more than 50,000 hours.
3. Environmental protection, LED materials are made of environmentally friendly materials, and do not contain polluting and toxic substances.
4. Energy saving. Compared with ordinary incandescent lamps and fluorescent lamps with the same power, the power of LED Lamps is only 1/6 of that of incandescent lamps and 1/2 of that of fluorescent lamps.
Light pole

The height of the light pole should be determined according to the width of the road, the distance between lamps, and the illuminance standard of the road. It can be equipped with distinctive lamp poles according to local characteristics, so that the lamp poles have both beautiful and energy-saving characteristics.

Street lights are widely used in our lives. They can be seen everywhere on roads and in communities. Street lights bring light to our night.
With the continuous consumption of energy and the increasing scarcity of resources, the greenhouse effect is becoming more and more harmful to humans, and the atmospheric environment is becoming more and more serious to the earth. International calls for energy saving and consumption reduction are getting higher and higher. Today, energy saving has become a country in the world. The top priority of work. my country officially launched the green lighting project as early as 1996, and proposed that outdoor lighting projects should save resources, prevent pollution, and benefit future generations. Over the years, through the joint efforts of all walks of life, as the fourth generation of light source semiconductor lighting products, there has been a rapid development and remarkable achievements in energy saving.
my country’s outdoor lighting accounts for about 30% of the entire lighting power consumption, which is closely related to people’s production and life. Street lamp as an important application of outdoor lighting, its advantages:
Long lifespan of high-power street lights: For this focus issue that everyone pays great attention to, as many domestic and foreign experts and companies` product brochures describe 50,000-100,000 hours, and they are optimistic. In fact, the life of high-power street lights depends on The following points:
(1) The chip quality and light attenuation value of the street light source.
(2) The packaging quality of street lights. Consistency and reliability.
(3) Street lamps are used as cold light sources, but the semiconductor itself generates heat. The heat dissipation of street lamps ensures good working conditions of street lamps.

(4) The life quality assurance of power supply and constant current drive.

1 Introduction
Solar integrated light, also called integrated Solar Street Light, is a combination of high-efficiency solar panels, 8-year long-life lithium batteries, high-efficiency LEDs and intelligent controllers, PIR human body sensing modules, and anti-theft mounting brackets. Integrated solar street lights, also called integrated solar street lights or integrated Solar Garden Lights. Because of its easy installation, integrated solar street lights are very popular in the market.

2. Working principle:
The integrated solar street light is converted into electric energy by solar panels, and then the Lithium Battery in the integrated solar street light is charged. In the daytime, even in cloudy days, this solar generator (Solar Panel) collects and stores the required energy, and at night automatically supplies power to the LED lights of the integrated solar street light to achieve night lighting. At the same time, the integrated solar street light has PIR human body induction Function, can realize the infrared induction control light work mode of the intelligent human body at night, 100% bright when there are people, and automatically change to 1/3 of the brightness after a certain delay when there is no one, which saves more energy intelligently. At the same time, as a kind of “inexhaustible and inexhaustible” safe and environmentally friendly new energy, solar energy plays an important role in integrated solar street lights.

Solar energy (Solar Energy) generally refers to the radiant energy of sunlight, which is generally used to generate electricity in modern times. Since the formation of the earth, organisms have mainly survived by the heat and light provided by the sun. Since ancient times, humans have also understood that the sun can dry objects and use them as a method of preserving food, such as salt production and salted fish. However, with the reduction of fossil fuels, solar energy is deliberately developed further. There are two ways to use solar energy: passive utilization (photothermal conversion) and photoelectric conversion. Solar power is an emerging renewable energy source. In a broad sense, solar energy is the source of many energy on the earth, such as wind energy, chemical energy, water potential energy and so on.
The Integrated Solar Street Lamp/yard lamp is an integrated solar product. The simple shape combines the best green energy combination (solar panel, super bright semiconductor LED light source, lithium iron phosphate battery). Equipped with human body intelligent induction system, it realizes low power consumption, long time, high brightness, 8 years of life and maintenance free.

3 structure composition:
The main composition of the solar integrated light (integrated solar street light): an integrated light (built-in: high-efficiency photovoltaic modules, large-capacity lithium battery, microcomputer MPPT intelligent controller, high-brightness LED light source, PIR human body sensor probe, anti-theft mounting bracket), Two parts of the light pole

4. Application
Installed on various traffic roads, auxiliary roads, residential roads, courtyards, mining areas and places where electricity is not easy to pull, park lighting, parking lots, rural areas, etc. to provide road lighting at night, and solar panels charge batteries to meet lighting;

5. Advantages of integrated solar street lights
Benefits of integrated solar street light:
Because it is an integrated solar street light (also known as high-efficiency solar panel, long-life lithium battery, high-efficiency imported LED, and intelligent controller, as well as PIR human body sensor module, anti-theft mounting bracket, etc. Integrated solar street light/yard light). The advantages of the Angel Eye integrated solar street light are simple installation and light weight. Generally, two workers only need a special wrench in the product to complete the installation in 5 minutes without using heavy equipment and tools.

At present, my country is creating a resource-saving and environment-friendly society, and the concept of “green lighting” is gradually gaining popularity. With the continuous advancement of science and technology and the rapid development of semiconductor material application technology, low-power LED light sources have been widely used in landscape lighting, and high-power LED Street Lights have attracted more and more attention from all aspects.

The luminous principle of LED lights:
LED (Light Emitting Diode), a light-emitting diode, is made of III-IV group compounds. It is a solid-state semiconductor device that can directly convert electricity into light. The heart of the LED is a semiconductor chip. The semiconductor chip consists of three parts, one part is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor. When the current acts on the chip through the wire, the electrons and holes will be pushed into the quantum wells. In the quantum wells, the electrons and holes recombine and then emit energy in the form of photons. This is the principle of LED light emission. The wavelength of light is the color of light, which is determined by the material forming the P-N junction.

The luminous principle of high pressure sodium lamp:
The high-pressure sodium lamp uses electricity to generate an arc between the electrodes at both ends of the arc tube. Due to the high temperature of the arc, the sodium amalgam in the tube is heated and evaporated into mercury vapor and sodium vapor. The electrons emitted by the cathode impact and discharge during the movement to the anode. The atoms of the substance gain energy to produce ionization or excitation, and then return from the excited state to the ground state; or from the ionized state to the excited state, and then return to the ground state in an infinite loop. At this time, the excess energy is released in the form of light radiation. Then there is light.
High-power Led Street Light is a new type of lighting method that realizes the lighting needs by illuminating the light-emitting diode group by DC low voltage. It has the characteristics of high brightness and good color rendering. In addition, because the input of LED street light is low voltage DC, it can be compared with The combination of solar energy makes solar LED street lights a possibility for road lighting in the future.

For the application in coastal projects, the products can be processed from the following aspects:
1. The choice of LED lamp beads: In the humid environment of coastal areas, small LED Lamps are prone to electrode migration, resulting in the so-called “caterpillar” phenomenon. In the project, we will choose a light tube with a larger luminous tube volume as much as possible while ensuring the dot spacing to reduce the “caterpillar phenomenon.”
2. Protection of components: For exposed components, in order to reduce the contact with moisture and salt in the air, and to extend the service life of the components as much as possible, the surface of the components on the back of the box can be painted with three-proof paint .
3. Protection of LED lamp beads: LED lamp beads are an important part of the LED display. In order to ensure the service life of the lamp beads in the environment of high salt and high humidity, the surface of the LED lamp beads is coated with nano protective coating. This paint is a colorless, transparent material that forms a nano-protective layer on the surface of electronic components to completely cover the pins of electronic components, effectively preventing electronic product components from wading in water and being corroded by acid and alkali salts. Under the premise of not affecting the LED display effect, the erosion of the LED lamp beads by the external environment is reduced, and the service life of the LED lamp beads is increased.

The most widely used street lamps in the construction of new rural areas should be Led Street Lamps or solar street lamps. They are mainly energy-saving and can ensure the lighting effect. They can kill two birds with one stone. Use solar street lamps in remote mountainous areas or areas with relatively low power system coverage. It is the most wise to choose the object, because it has the lowest requirements for the surrounding conditions, it can illuminate as long as there is the sun, the least picky and the easiest to form street light products, and the most cost-effective one is the 6-meter Solar Street Light. With hot sales and high penetration rate, let’s talk about the reason and inevitability of it below.

The price of conventional rural 30-watt 6-meter solar LED street lights is more than one thousand four yuan and less than one thousand eight yuan, and the corresponding configuration can basically meet all regions of the country. The price range is because of the different places of use and the different lighting time requirements , The quotation is not unique due to different rainy and cloudy conditions, and it needs to be customized. You can contact the manufacturer.

Solar street light manufacturers discuss the practicability of 6-meter solar street lights. The first thing to consider when making solar street lights is the height of the light pole. The height of the light pole is determined by the width of the road where it is used. It is said that basically four-way roads with auxiliary roads, so the natural road width must be more than ten meters, then the height of the light pole must be about 8-10 meters, and the auxiliary roads require solar street lights to be made of double arms. The arm is 80-100 watts, and the auxiliary arm is 30 watts, but if the basic road width in rural areas does not exceed 5 meters, this determines that the height of the light pole must not exceed 6 meters, usually between 4.5 meters and 6 meters. Today, I will focus on the quotation of this rural 6-meter solar street light. The height of the light pole has been determined.

The following is the wattage of the light source. 6 meters usually corresponds to 25-30 watts, the latter is mostly, and then the Solar Panel and battery configuration are required. Usually, the lighting requirements for the 6-meter solar street light in rural areas start from five or six o`clock in the dark By about 12 o`clock at night, almost everyone`s home was already asleep. There were almost no pedestrians on the road. The street lights were no longer effective. Older people have a small problem. They can`t fall asleep when the lights are on. The street lights are too bright. Long time will also affect the normal work and rest of farmers, which is a bit self-defeating, so the most reasonable is 6 hours a day. The battery configuration is determined according to the local rainy weather conditions. In some areas, there are few days of rain throughout the year. The battery configuration is low, and some three-day rain configuration is higher, but the overall impact on the price of 6-meter solar street lights is not particularly large, and they are all acceptable.

With the rapid development of solar photovoltaic power generation technology, solar street lights have quickly been promoted and applied in the vast cities and rural areas, especially in the rural areas without power grids, 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, on the other hand, it also causes a waste of 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 week. 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 them, we must adapt to local conditions, use them rationally, and match them reasonably to give full play to its good lighting effect.
