The working principle of solar street lamp is provided to convert solar energy into electrical energy to realize lighting, street lamp is at the top of solar panels or photovoltaic modules, photovoltaic components during the day these made of polysilicon in the battery will store solar energy into electricity, the solar lights under the control of intelligent controller, solar panels after sunlight irradiation, absorption the solar light and convert it into electricity, solar battery components to the battery charging. In the evening, the electric energy is transmitted to the light source by the controller to illuminate the night. In the evening, the battery pack supplies power to the LED light source for power supply and realizes the lighting function.

Solar street lights are powered by solar energy, so there is no cable, no leakage and other accidents. The DC controller ensures that the battery pack is not damaged due to overcharge or over discharge, and has the functions of light control, time control, temperature compensation, lightning protection and reverse polarity protection. There is no need to lay cables, no AC power supply, no electricity bills.

Solar street lamp of low carbon, environmental protection, safety and reliability and a series of advantages, has been recognized by customers, so it has been vigorously promoted. Therefore, it can be widely used in urban main, secondary roads, residential areas, factories, tourist attractions, parking lots and other places.
