The principle of solar lamp technology



The working principle of solar lamp is simple, the use of solar photovoltaic effect principle, daytime solar panels and solar radiation into electrical energy output, through the charging and discharging controller is stored in the accumulator. When night illumination gradually reduced to about 101ux, the solar battery board open circuit voltage of about 4.5V, the charge and discharge controller to detect the a voltage value of the battery discharge lamp action. After the battery discharge 8.5H, charge discharge control action, the battery discharge end. The main function of the charge and discharge controller is to protect the battery.
