An optimization algorithm to provide individual illuminance using LED ceiling lights and verification at the actual office

摘要

Optimization algorithm has been proposed to provide individual illuminance. With this algorithm, schematic position between light and illuminance sensor is understood with correlation to accelerate convergence into the target illuminance. This system has been introduced into actual offices in Tokyo, Japan. The experiment showed that significant energy saving is possible, and found several points for improvement of both light and algorithm. Intelligent Lighting System was developed by using LED ceiling light, and its effectiveness was verified. Furthermore, effective algorithm is proposed to obtain relation between light and illuminance sensor in an actual office.
