Lighting energy consumption accounts for a considerable proportion of the total energy consumption of industrial plants. Therefore, finding effective energy-saving transformation solutions is of great significance to reducing energy consumption and protecting the environment.

[0003] In the existing technology, the lighting control function of industrial plants is single. Although intelligent LED lighting products have gradually penetrated into the industrial market, the lighting systems of many factories still remain in the traditional control mode, failing to fully utilize the advantages of intelligent and artificial intelligence technologies. The common manual control of turning on or off lights through switches relies on personnel management, which is difficult to achieve supervision and management. After turning on the lights, they are often in a state of lighting all day, causing serious energy waste. And it is impossible to accurately adjust the lighting intensity according to the changes in light in the external environment, resulting in unnecessary energy loss and the lighting needs are not met;

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention
