照明光色對閱讀行為時主觀心理評價之影響

Research on the Effects of Color of Light on Subjective Evaluation while Reading Papers

本研究考量未來照明環境多彩化的可能性，探討了照明光色的改變對閱讀行為時主觀心理評價的影響。結果發現，不同的照明光色對閱讀行為時閱讀者所感知的明亮感、眩光程度、溫冷感與舒適度皆有顯著影響，而對疲勞感則無顯著影響。整體而言，2800K 黃色光具有明亮感較低、眩光較低、舒適度較高以及使人感到溫暖的心理效果。13850K 淺藍色光具有明亮感較高、舒適度較低以及使人感到涼爽的心理效果。5200K 白色光在各指標的表現多介於2800K 黃色光與13850K 淺藍色光之間。粉紅色光則具有眩光較高以及舒適度較低的缺點。綜上所述，光色確實會改變照明環境的特性，因此未來應可依據使用目的與意匠的不同，善用光色因子來塑造更理想的照明環境。
