Lean production is the process of transforming the production system through changes in system structure, personnel organization, operational methods, and market supply and demand. It enables the production system to quickly adapt to the constantly changing needs of users and streamline all useless and redundant things in the production process, ultimately achieving the best results in all aspects of production, including market supply and sales

The practice of lean production has been around for half a century since the Japanese began. Compared to the mass production methods in the United States, lean production has reduced human resources (including product development, production systems, and other departments in the factory) to 50%, reduced new product development cycles to 50%~66%, reduced factory space occupancy to 50%, reduced finished product inventory to 25% of the average inventory level in mass production factories, and increased product quality by three times... It has brought about a quantitative improvement and transformation in enterprise production efficiency. Therefore, lean factories have more precise and detailed requirements in 5S, just in time production, value stream analysis, waste elimination, continuous improvement, error prevention, comprehensive preventive maintenance, rapid switching, team building, and employee participation. The smart lighting system has become an important management tool for information management in lean factories.
