心理・生理反応から評価した好みの色温度と室温の組み合わせに関する実験的研究 : その3 照度が1,500ルクスの場合の中年女性の好みの色温度の季節差

Abstract

Kruithof demonstrated the preferred combination of illuminace levels and color temperatures. However, a seasonal change and the gender difference in such preference have not been sufficiently examined. Following the previous studies, eight female subjects aged from 30 to 40 yrs were exposed to lighting of 3,000 K and 7,500 K with the combination of room air temperatures (22℃/30℃) at the same illumination level (1,500 lx) following 30min control exposure at 25℃ in darkened room. Experiments were carried out in summer and winter. Skin temperatures, ECGs, finger blood flow, blood pressure and oral temperature were measured. Thermal sensation, thermal comfort and sensation of intensity of illumination were reported on given categories at 15-min. intervals. Evaluation of the physiological responses indicated that high color temperatures were preferred in both seasons, particularly during cool exposureand agreed with Kruithofs proposal.
