Recently, the China Underground Electric Car Park Lighting Energy Saving Industry Development Forum was held by the China Building Electrical Industry Alliance. The first underground parking lot intelligent lighting energy-saving system in China attracted the attention of the industry.
In recent years, many underground parking lots built in various parts of China have not only installed a large number of light sources, but also burned a lot of electric energy for 24 hours of lighting. This system developed by Warwick Kaide Lighting Technology (Beijing) Co., Ltd. uses a combination of LED light source and intelligent controller. When someone or car needs to be illuminated, the system will run in the highlighted state, otherwise the festival will be maintained. The low-light state of electricity saves more than 80 energy than traditional lighting.
