Abstract
The position of the light source, illuminance distribution, and color temperature were evaluated in each lighting environment for the three main activities in a living room ? ‘watching TV,’ ‘reading’ and ‘relaxing.’BR In ‘watching TV’, The experiment was done to estimate the degree of comfort felt by the subjects when they watch static video and moving video, respectably, with different ambient brightness, with or without partial lighting above the TV set, and with different color temperatures. In ‘reading’ the comfortableness was estimated by the illuminance ratio of the ambient lighting to the lighting for reading and by the difference in color temperature. And in ‘relaxing’, the comfortableness was estimated by means by means of the ambient brightness, use/no use of a relaxing lamp, and color temperature. This experiment determined the general satisfaction for each visual act and the optimum lighting environment to reduce glare.
