Basic composition of folding system

Taking "Shandong Xuguang Solar Street Lamp" as an example, the system consists of solar cell components, LED lamp holders, batteries, controllers, lamp poles, and other main components; The solar panel has a light efficiency of 127Wp/m2, which is highly efficient and beneficial for the wind resistance design of the system; The lamp head is a planar light source consisting of a lattice of 1W white LED and 1W yellow LED arranged at a certain distance on the printed circuit board.

Folding working principle

Solar cells made using the principle of photovoltaic effect. During the day, the solar panel receives solar radiation energy and converts it into electrical energy output. It is stored in the battery through a charge and discharge controller. At night, when the illumination gradually decreases to around 10lux and the open circuit voltage of the solar panel is 4.5V, the charge and discharge controller detects this voltage value and acts to discharge the battery to the lamp head.
