The main components of solar street lights are solar panels, batteries, controllers, and LED light sources. The working sequence: solar panel absorbs sunlight and converts them into electric energy, then the electric energy will be stored in the battery, finally the controller supplies power to the LED light source to achieve night lighting effects. The specific working principle as follows: Under the control of the intelligent controller, as a core part of solar lights products, during the day, the solar panel absorbs solar energy and converts it into electrical energy after being irradiated by sunlight. The electrical energy converted from solar energy during the daytime charges the battery pack, and the battery pack provides power to the LED light source at night to achieve the lighting function.
