| Abstract |
This study examines visitors’ visual and psychological perceptions for lighting environments in exhibition spaces of art galleries to provide useful data for improvement of lighting environments in galleries. Field measurements and surveys were performed in three small galleries under various illuminance and luminance conditions. Results indicate that the glare and visual stimulus by light were perceived less, when the average illuminance and the luminance were low and the uniformity ratios of illuminance were high. As the luminance became lower, participants have seen art paintings unclearly, perceived space monotonously and felt difficult to concentrate on paintings. Visual discomfort caused by light was influenced by the glare from floor and the sensation of eye fatigue. Overall satisfaction for the ambience by light was also relevant to visual fatigue, visual satisfaction and sufficient brightness of space. |
