The solar lamp is composed of a solar battery module, some LED lamps, a control box (with a charger, a controller, and a battery in the control box) and a lamp post.
The solar panel has a light efficiency of 127Wp / m2, which has a high efficiency and is very beneficial to the wind-resistant design of the system; the lamp head part is integrated with a 1W white light LED and a 1W yellow light LED on a printed circuit board and arranged in a lattice with a certain pitch as a flat surface light source.
The control box body is made of stainless steel, which is beautiful and durable; the maintenance-free lead-acid battery and the special charging controller for solar street lamps developed by the patent technology of slow pulse fast charge and discharge are placed in the control box.
The system uses valve-regulated sealed lead-acid batteries. Because of its low maintenance, it is also called "maintenance-free battery", which is helpful to reduce the cost of system maintenance. The charge and discharge controller is designed with full functions (with light control, Time control, over-charge protection, over-discharge protection and reverse connection protection, etc.) and cost control to achieve a high cost performance.
