Operation method:
When sunlight shines on the solar cell array, it is converted into electric energy. The current passes through the diode and is sent to the rechargeable battery and bulb flash device. During the day, that is, when there is light, there is charged electric energy for the flashing device to work. At night, that is, after the light stops, it is powered by the electric energy stored in the. The size of solar cell module and battery configuration determines the length of lighting time. The photoelectric conversion rate of solar cell module and light efficiency of light source determine the high and low cost of solar lamp.
