The operation process of the split-type solar street light follows the basic principles of energy conversion and storage During the day, the solar panel is exposed to sunlight, and through the photovoltaic effect, it directly converts sunlight energy into direct current energy. This electricity is not used directly for lighting, but is regulated by the smart charge-discharge controller and stored in the energy storage battery. When nightfall comes or the ambient light intensity drops below a certain threshold, the controller automatically switches the circuit, releasing the accumulated energy from the storage battery to drive the efficient LED light source for illumination. The entire process requires no human intervention, achieving fully automated energy management and lighting control.
