A solar lamp is an electric lamp converted into electricity by a solar panel. During the day, even on cloudy days, this solar generator (solar panel) can also collect and store the sun's energy. As a kind of safe and environment-friendly new lamp, solar lamp has been paid more and more attention.
The solar lamp is composed of solar cell module, some LED lamps, control box (the control box has charger, controller, battery) and lamp pole. The light efficiency of solar panels reaches 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 as a certain distance dot matrix as the plane light source. The control box body is made of stainless steel, beautiful and durable; A maintenance-free lead-acid battery and a special charging controller for solar street lamp developed by slow pulse fast charging and discharging patented technology are placed in the control box. Valve-controlled sealed lead-acid battery is used in the system. It is also called "maintenance-free battery" because of its little maintenance, which is beneficial to reduce the maintenance cost of the system. The charge and discharge controller is designed with full functions (light control, time control, overcharge protection, overdischarge protection and reverse connection protection) and cost control to achieve high cost performance.
