The basic structure of the solar lamp

The solar lamp is composed of solar cell module, some LED lamps, control box (the control box has charger, controller and battery) and lamp pole. The solar panel has a light efficiency of 127wp / m2, which is very beneficial to the wind resistance design of the system; In the lamp cap part, 1W white LED and 1W yellow LED are integrated on the printed circuit board and arranged into a dot matrix with a certain spacing as the plane light source. The control box is made of stainless steel, beautiful and durable; The maintenance free lead-acid battery is placed in the control box and the special charging controller for solar lamp is successfully developed by using the patented technology of slow pulse fast charging and discharging. Valve regulated sealed lead-acid battery is selected for the system. It is also called "maintenance free battery" because it has little maintenance, which is conducive to reducing the maintenance cost of the system; The design of charge discharge controller takes into account the complete functions (including optical control, time control, overcharge protection, over discharge protection and reverse connection protection) and cost control, so as to achieve high cost performance.
