조명방식 및 색온도 조건에 따른 실내의 조명환경 인지분석

Abstract

The influences of lighting conditions, which is combined by color temperature and lighting types, on visualresponses are discussed in this study. Visual annoyance tests were performed in a full-scale mock-up test space, whichwas prepared for a small private office environment. Lamps with color temperature of 3,500 K and 5,000 K wereapplied to a direct lighting type and direct/indirect lighting type. Results indicate that overall glare sensation for computer-based task was stronger than that of paper-based task. Color temperature of 3,500 K applied to a direct lightingtype caused the worst glare. Overall, visual discomfort were not reported under all lighting conditions. The direct/indirect lighting type succeeded to ensure better comfort compared to the direct lighting type. The number of letterswhich were typed in showed no significant difference under all lighting conditions. In order to enhance good qualityof lighting condition, the direct lighting type should ensure good color rendering, reduction of glare and prevention oftensed sensation. The direct/indirect lighting type condition should keep the space and desktop surface bright.
