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.

With the continuous development of solar energy technology, Solar Street Light products are becoming more and more popular. Many rural areas have installed solar street lights, but there are many things to pay attention to when installing solar street lights, especially when choosing installation sites and pre-embedded foundations. Will pay attention, so the use of solar street lights is not good, so what should we pay attention to when choosing the installation location and pre-embedded foundation?

1. Choice of installation location
The installation site must have sufficient sunlight throughout the day, without any obstructions. Make sure that the installation site is far away from trees, high-rise buildings and other obstacles that will block the sun. There should be no direct light source above the Solar Panel, otherwise the street light system will not work properly. Solar street lights must be far away from heat sources , Otherwise the battery life will be greatly shortened. The foundation of the solar Street light pole must be poured in a sufficiently solid clay layer. If the installation site is atypical soil layers such as sand or frozen soil, please inform us in advance so that we can take specific countermeasures. The solar panels must face south and ensure that the installation site faces south without obstructions.
2. Building the foundation
Ensure that the inner test nut is screwed to the end of the thread, and leave enough length for the flange of the solar street light pole to ensure that the four bolts are on the same horizontal line. It is recommended to use a level to test and assemble the upper end of the thread with tape to prevent cement blockage Thread.
Three, installation basis
Dig the foundation pit according to the basic map provided by the solar street light manufacturer. At the same time, concrete can be prepared. Put the basic cage into the foundation pit, use a level to ensure that the basic cage is placed horizontally, and compact the basic cage. Make sure that the upper thread of the anchor bolt is protected by tape. Pour the concrete and keep the level of the foundation cage. It is recommended that the concrete just cover the fixing plate and the nuts on it to prevent it from rusting. Clean the top of the foundation and level it with a trowel. After 3-7 days, confirm that the concrete is completely solidified and dry, and then remove the insulating board/brick.
The above are the items that need special attention in the installation of solar street lights. We must pay attention to the installation to avoid the phenomenon of non-lighting or poor lighting effects.
