The Effect of Electric Lamp on Visual Perception

광원(光源)의 색온도(色溫度)·연색성(演色性) 및 휘도(輝度)레벨이 시지각(視知覺) 변화에 미치는 영향

This paper deals with the effects of fluorescent lamp description and luminance level on the occupant's brightness perception and other sensation in building interiors. The following experiments were conducted: the subjects compared on room lit by daylight fluorescent lamps with the other room lit by the different lamp description at equal luminance at equal luminance level. The degree of that effect decreased with a rise in luminace level. The brightness perception had high correlation with the visual clarity and no correlation with favorite sensation.
