Solar energy Lamp Working principle is simple, make use of the solar cell of the principle of the light produce volt effect, solar panel receives solar radiant energy and converts to electric energy output in daytime, pass charge and discharge controller store in battery.
Night when the illumination gradually reduced to about 101ux, solar panel open circuit voltage of 4.5V, charge and discharge controller detected this voltage value after the action, battery to the lamp discharge. Battery discharge after 8.5h, charge and discharge control action, battery discharge end. The main function of charge and discharge controller is to protect the battery.
