Functions and working methods of important components of
solar street lights
On the principle diagram of solar street light, we can see that the solar street light system is composed of four parts: LED lamp holder, solar battery pack (including battery pack bracket), controller box (including battery and controller) and light pole.
First, the index of each departmental component of solar street light
The photoelectric conversion efficiency of solar panels can reach 127 WP per square meter. The conversion efficiency is high-grade. The design of solar street lights requires high wind resistance. LED white light lamps usually use 1w. On the LED module board, in addition to the white light LED points, there are also yellow LED points placed at intervals. Together with the white light points, they form the LED road lighting source.
Second, the solar street light control box is rich in content and strong in importance
Control boxes are usually made of stainless steel. Jiangsu Naite Lighting Electric Co., Ltd. is a manufacturer engaged in the production and design of solar street lights and high-pole lights. It has 20 years of experience in the production of solar street lights and builds the most professional solar street light manufacturer. Contact number: 13805257308. , It is very beautiful and unsightly, and it also has the characteristics of durability. The control box has a lead-acid battery controller with charging and discharging monitoring capabilities. The lead-acid battery is a sealed valve control type, and the battery system has very little maintenance. , Designers call it 'maintenance-free batteryAnother very important part of the principle diagram of solar street lights is the charge and discharge controller.
Third, the technical advantages of the new charge and discharge controller
The latest type of charge and discharge controller has got rid of the shackles of the past overcharge protection function, and has more comprehensive functions. The new model can complete time control, luminosity control, overdischarge protection, overcharge protection, etc. Series of important tasks, the cost-effective improvement is very obvious.
Fourth, the basic working principles of solar street lights
At this moment, the mainstream solar street lights are all operating photovoltaic principles, using solar photons to irradiate the solar panels to generate current, which is stored in the battery, and then the LED lights are supplied with energy through the battery, and then the electric energy to the light energy is mutually realized. Transformed. At night, the outside light level is less than ten LUX, the solar panel is turned on, and the voltage of 4.5 volts is released, the battery controller obtains the voltage command and starts to work, the controller opens the valve to the LED lamp holder, and the street lamp lights up.
After the street lights are turned on, another command of the battery controller---the time command starts to start, and the street lights start to count at 20 o'clock in the evening, and then 8.5 hours later, that is, at more than 4 o'clock in the morning. Then you can turn off the lights to complete the task of solar street light principle diagram lighting.
