What is the system composition of solar street lights, and what is the working principle of solar st

Solar street light is a lighting device that uses solar energy to generate electricity, which is composed of solar panels, batteries, controllers, LED lights and brackets, etc.

First of all, solar panels are the core components of solar street lights, which convert solar energy into electricity. Solar panels are typically made up of multiple solar cells that convert sunlight into direct current through the photovoltaic effect. Solar panels are usually installed on top or on the side of street lights to maximize sunlight reception.

Secondly, the battery is the energy storage device of the solar street light. During the day, solar panels convert solar energy into electricity and store the excess energy in batteries. At night or on cloudy days, the battery releases stored electrical energy for the LED lights.

The battery is usually a lead-acid battery or a lithium battery, which has a high charge-discharge efficiency and a long life.

The controller is an intelligent management system for solar street lights, which is used to control the charging and discharging process of solar panels, as well as to control the brightness and switch of LED lights. The controller usually has functions such as light control, time control, and temperature control, and can automatically adjust the solar energy according to parameters such as ambient light, time, and temperature.

The working principle of solar street lights is to convert solar energy into electrical energy to achieve lighting effect. At the top of the street lamp are solar panels, also called photovoltaic modules. The modules on the solar PV module are made of polycrystalline silicon.

During the day, polysilicon absorbs solar energy and converts it into electricity, which is stored in a battery. Under the control of the solar street light intelligent controller, the solar panels are irradiated by sunlight, which is then converted into electricity through the sunlight in the western area. During the day, the solar module continuously charges the battery.

At night, the electric energy is transmitted to the light source through the intelligent controller, so that the solar street lamp can achieve the effect of night lighting. Batteries are provided.

Because solar street lights generate electricity by absorbing sunlight, solar street lights have no cables, no accidents such as electricity leakage, and no electricity bills. And it is widely used for rain and lightning protection, and many urban main and secondary roads, residential areas, factories, parks, and tourist attractions have adopted solar street lights.

The solar cell made by the principle of photo-generated volt effect should be made during the day solar panel receives solar radiation energy and converts it into electrical energy output, which is stored in the battery through the charge and discharge controller, and at night when the illumination is gradually reduced to about 10lux, the open circuit voltage of the solar panel is about 10lux, and the charge and discharge controller detects this voltage value after acting, and the battery discharges the lamp head! To put it simply: the solar panels will absorb the solar energy and convert it into electricity, which will be stored in the battery for use at night.

Accumulators are divided into lead-acid batteries and gel batteries.

Under the control of the intelligent controller, the solar panel absorbs the solar light and converts it into electrical energy through the irradiation of the sun, and the solar cell module charges the battery pack during the day, and the battery pack provides power to the LED light source at night to realize the lighting function. The DC controller can ensure that the battery pack is not damaged due to overcharge or overdischarge, and has the functions of light control, time control, temperature compensation, lightning protection, reverse polarity protection and so on.

When installing solar street lights, there is no need to install complex circuits, just make a cement base, make a battery pit, and fix it with galvanized bolts. There is no need to consume a lot of manpower, material resources and financial resources. Solar street lamps are a one-time investment and long-term benefits, due to the simple wiring, no maintenance costs, and no expensive electricity costs.

6-7 years to recover costs, 3-4 years to save more than 1 million electricity and maintenance costs. It can save the high electricity cost of the city circuit lamp, the complex line, and the need for long-term uninterrupted maintenance of the line handqin road. In the case of special voltage instability, it is inevitable that the sodium lamp is prone to breakage, and with the extension of the hidden life, the line aging and maintenance costs are increasing year by year.

The solar street light system can ensure the normal operation of the tomb for more than 15 days in rainy weather! Its system composition is composed of LED light source (including drive), solar panel, battery (including battery incubator), solar street lamp controller, street lamp pole (including foundation) and auxiliary materials and wires.

Solar cavity grip cell modules generally use monocrystalline silicon or polycrystalline silicon solar cell modules; LED lamp heads generally use high-power LED light sources; The controller is generally placed in the light pole, with light control, time control, overcharge and over-discharge protection and reverse connection protection, and the more advanced controller has the function of adjusting the lighting time in four seasons, half-power function, intelligent charging and discharging function, etc.; The battery is generally placed underground or there will be a special battery incubator, which can use valve-regulated lead-acid battery, gel battery, iron-aluminum battery or lithium battery. The solar luminaires work fully automatically, and there is no need to dig trenches and wiring, but the poles need to be installed on the embedded parts (concrete bases).

The working principle of the system is simple, the solar cell made of the principle of photogenerated volt effect receives solar radiation energy during the day and converts it into electrical energy output, which is stored in the battery through the charge and discharge controller, and at night when the illumination is gradually reduced to about 10lux, the open circuit voltage of the solar panel is about 10lux, and the charge and discharge controller detects this voltage value and acts, and the battery discharges the lamp head. After the battery is discharged for an hour, the charge and discharge controller acts, and the battery discharge ends. The main function of the charge and discharge controller is to protect the battery.

The main function of the charge and discharge controller is to protect the battery.

Solar street lamp is a kind of lighting equipment that uses solar energy to generate electricity and store energy to supply street lighting. Its working principle mainly includes three processes: solar energy collection, conversion and storage.

First, solar street lights collect solar energy through solar panels. Solar panels are made up of multiple solar cells that convert sunlight into direct current. When sunlight hits a solar panel, the photons excite the electrons in the solar cell, causing them to jump into the conductive band, forming an electric current.

In this way, the solar panels are able to convert solar energy into electricity.

Secondly, the solar street light stores electrical energy into the battery through a charge controller. The charge controller is an important device that connects the solar panel and the battery, it is able to monitor the voltage and current output of the solar panel, and carry out charging control according to the state of the battery. When the voltage and current output by the solar panel reaches a certain value, the charge controller stores the electrical energy into the battery.

In this way, the battery is able to store the electricity collected by the solar panels.

Finally, the solar street light supplies the stored electrical energy to the street light through the controller. The controller is a key device that connects the battery and the street lamp, it is able to monitor the voltage and current of the battery, and control the output of electrical energy according to the lighting demand of the street lamp. When solar panels are unable to collect solar energy, or in unlit conditions such as at night or on cloudy days, the controller automatically supplies the electrical energy stored in the battery to street lighting.

In this way, the solar street lights can be automatically controlled and illuminated according to the ambient light conditions and the needs of the street lights.

In general, solar street lights work by collecting solar energy through solar panels, the charge controller stores the electrical energy into the battery, and the controller supplies the stored electrical energy to the street lighting. This working principle makes the solar street lamp have the advantages of independent power supply, environmental protection and energy saving, automatic control, etc., and become a lighting solution that can be continuously developed.

There are many types of lamps and lanterns on the market today, and solar street lights are one of them. So the question is, do you know what is the working principle and construction of solar street lights? How to choose solar street light poles? Let me give you a brief introduction.

The principle is that when the light is mapped on the solar panel during the day, the solar panel converts the light energy into electricity and stores it into a lithium battery; At night, when the light is weakened, the stored electrical energy is transported to the lamp head to light up the street lamp. Today's solar street lights are mainly composed of five parts: light poles, lamp heads, battery panels, controllers and lithium batteries.

How to choose a solar street light pole.

1.height of requirements.

Since the height of the light pole is determined by the illumination of the street light, it must be chosen carefully and the height is determined according to the width of the road. For example, the height of the single-sided street lamp is greater than or equal to the road width, the height of the double-sided symmetrical street lamp is equal to the road width, and the height of the double-sided zigzag street lamp is not less than 70% of the road width, so that the best lighting effect is achieved.

In addition, the amount of traffic on the road should also be taken into account. For example, there are many large trucks, and the height of the light pole is appropriate. On the contrary, if there are not many large trucks, then the light pole can be lower. Of course, don't deviate from the standard in terms of height control, otherwise the consequences will be very serious.

2.Material requirements.

Of course, the material is also an important criterion for choosing a light pole, as it affects the service life of the street lamp. Nowadays, it is more common to make Q235 steel coils, and the corrosion resistance of this material is not very good, so the surface will be processed to enhance this performance.

In addition, we often see that some of the lamp covers are stainless steel and anodized. These two materials have excellent corrosion properties, but from the best point of view, steel poles are not so cheap. For this reason, you can decide according to your specific budget.
