[0002] The smart lighting market is growing rapidly, and the integration of technology with the Internet of Things, artificial intelligence and other fields has promoted product innovation. With the whole society's attention to the green cycle and low-carbon development goals, the intelligent and low-carbon lighting of parking areas, as well as the energy saving and carbon reduction of the entire upstream and downstream industrial chains have become the focus of technological development in the current society. However, the lighting solutions that are currently widely used are mostly time-sharing, flow, and single-lamp sensing, which have average actual use effects, poor lighting experience, high costs, complex wiring, and difficult construction.

[0003] In existing parking lots, parking space occupancy indication and lighting are two separate systems that need to be constructed separately. On the one hand, the lighting system cannot provide light for the parking space occupancy detection camera, so the camera effect is poor and there are many misidentifications. In addition, existing parking space occupancy indication systems all need to use wired communication, which requires the layout of separate bridges and wiring when implemented.
