Summary: 
We focus on office lighting environment and conduct a study of Intelligent Lighting System that provides light brightness in accordance with an individual office workers' needs. For purpose of commercialization of this system, Intelligent Lighting System using in-office frame was introduced at Kokuyo Co., Ltd. This place is a special work area used for meetings and discussions, etc. In system verification of operability of illuminance and color temperature, illuminance was converged in approximately 100 seconds and color temperature of which difference from target color temperature was within 40 Kelvin was provided in areas with little impact of outer light.
