Usually, LED lights installed outdoors are charged by installing photovoltaic panels and photovoltaic controllers on the light poles. During the day, the photovoltaic panels convert light energy into electrical energy and supply it to the solar battery. At night, the solar battery supplies power to the LED lights, making it possible to illuminate outdoors where it is difficult to access municipal power.
