The solar energy receiving unit comprises a main body and a bottom cover. Inside the top of the main body, a solar panel is installed to capture sunlight; this solar panel features a base fixedly connected beneath it and a transparent protective cover positioned above it. The interior of the main body houses a battery compartment designed to hold a rechargeable battery.
A printed circuit board (PCB) containing the control circuitry is fixedly attached to the bottom cover via a connecting element; this PCB is electrically connected to the rechargeable battery, the solar panel, and a light-emitting diode (LED). The step light described herein directly utilizes inexhaustible, green solar energy, thereby significantly reducing electricity consumption and lowering installation costs.
