Working principle of LED street lamp

- Apr 03, 2019-

LED street lamp is based on the principle of photovoltaic effect of solar cells, solar cells absorb solar photon energy during the day to generate electricity, which is stored in the battery through the controller. When night falls or the brightness around the lamp is low to a certain value, the controller will discharge by itself and turn on the street lamp to start lighting. Therefore, when choosing and purchasing LED street lamps in different areas, we must pay special attention to whether the design ideas and key points of the system conform to the local actual situation, not only to save investment and pursue low prices blindly, but also not to waste resources blindly pursuing high performance.
