LIGHTING EFFECTS ON INTERIOR VISUAL ENVIRONMENT - IN THE LIVING ROOM

Effects of illumination upon the comfortableness of visual environment of a miniature-living room were examined under various lighting conditions, using the semantic differential method. Three components were extracted by principal components analysis. The first component, activity, was entirely affected by illuminance. The second, elcgance, was related to illuminance and color temperature. Color temperature was practically responsible for the third, warm feeling. Discrepancies were observed at lower color temperature levels when a relationship between illuminance and color temperature for pleasantness was compared with Kruithof's results. © 1979, The Japanese Psychological Association.
