A Lighting Control to Optimize Satisfaction of Illuminance and Color Temperature

Abstract

We have proposed an Intelligent Lighting System which individually provides illuminance and color temperature required by office workers. The Intelligent Lighting System has been introduced in several offices and its effectiveness is recognized. However, the Intelligent Lighting System can’t realize greatly different illuminance and color temperature required by adjacent office workers because of relation between lighting position and office layout. Therefore, in this research, we propose a new lighting control method which treats illuminance and color temperature satisfactory in the area rather than the specific value by using the index of satisfaction. The verification experiment showed that the proposed method is effective for improving the total satisfaction of all officers. Also, it showed that the proposed method is effective for energy saving lighting control.
