説明
This study investigates how the season and the correlated color temperature affect the impression of lighting. However, subjective evaluation inevitably has individual variation. Therefore, the purpose of this paper is to clarify how within- and between-subject variation changes. The experiment variables are the season, the illuminance of the room, and the correlated color temperature of the fluorescent lamp. The seasons are summer and winter, there are 12 levels of vertical illuminance of the room from 0.5 to 2000 lx, and the correlated color temperature of the lamps are 3000 and 6700 K. The subjects are 27 to 31 young women. They evaluate brightness, glare, comfort, and relaxation effect of the lighting. In conclusion : 1) Brightness, glare, and comfortable sensations change depending on the illuminance. The influence on the relaxation effect due to the illuminance is small, and the relation is clear for each individual. The subjects have suitable illuminance levels for relaxation. 2) All four items are influenced by the change of illuminance level in between-subject variation. The range of illuminance in which the evaluation between subjects stabilized is as follows: brightness is 500 lx or more, glare is 50 lx or less, comfort is from 20 to 50 lx, and relaxation is from 10 to 20 lx. 3) The variation between individuals is larger than the variation for each individual, though there is little difference with changes in illuminance.
