A Fundamental Study on the Photosensor Modeling for the Daylight Responsive Dimming System - Using RADIANCE Program

광센서 조광제어시스템에서의 광센서 모델링에 관한 기초적 연구 -RADIANCE 프로그램 활용-

The daylight responsive dimming system is an energy saving system that automatically controls lighting output of artificial lighting according to available daylight in inside, as well as keeps uniform workplace illuminance. The basic three components of the daylight responsive dimming system consist of a photosensor, a controller and a dimming ballast. This paper is a fundamental study of photosensor modeling for the daylight responsive dimming system. The correlation between photosensor illuminance on the ceiling and workplace illuminance is an important factor to accuracy of system performance, so that the purpose of this study is to improve accuracy for daylight responsive dimming system. This study performs to derive the optimized conditions of photosensor using the RADIANCE.
