LIGHTING ENVIRONMENT OF MIRRORS IN PUBLIC AND COMMERCIAL FACILITIES: Survey and experiment focusing on background environment

Based on the hypothesis that surrounding environment effects the pleasantness using mirror, survey was conducted to grasp the present situation in public and commercial facilities, and experiment was conducted to find the suitable background lighting. Survey included number of mirrors, lighting method, and distance till the back wall. Impression was evaluated by subjects and lighting environment such as vertical illuminance was measured in correspondence. 4 general lighting patterns were set for the experiment, asking subjects to adjust the mirror lighting. As a result, facial luminance varied by the background luminance. Optimal values were analyzed.
