Effects of Color Rendering Characteristics of Fluorescent Lamps on the Atmosphere in the Living Room

Abstract

We studied the effects of color temperature and color rendering of fluorescent lamps as well as chair color on the atmosphere in a living room.
Four factors-activity, evaluation, softness, gorgeousness were extracted as images of the living room by principal component analysis.
Color temperature had a strong effect on the atmosphere than color rendering.
Mutual effects on activity were found between color temperature and chair chroma and between color rendering and chair chroma. Evaluation was affected by relationship between color temperature and chair hue and between color temperature and chair chroma. Evaluation and softness were somewhat affected by color temperature versus color rendering.
Comfortable illuminance on the desk top was found to be 400-5001x and decreased with increasing color rendering index. Moreover, people tended to regulate it to increase the softness.
