研究指出改變色溫或c/p值,皆可對警覺度產生影響,然而卻很少有研究去探討色溫相差多少時,警覺度即有顯著性的提升。因此,本實驗採用10組自行調製的實驗色溫(TA),照度為325 ± 50勒克斯的光源,並實際於不同光源色溫下,對受試者進行腦波量測的人因實驗,觀察其警覺度客觀的變化。使用指數函數、內差法與10組實驗色溫 (TA)的c/p值,求出各實驗色溫(TA)的臨界色溫(TM),而臨界色溫(TM) 代表著是當實驗色溫(TA)上升至臨界色溫(TM)時其警覺度即達顯著提升。實驗結果建立一種可預測臨界色溫(TM)的模式化。
音樂同樣具有提高警覺度的效果,所以本研究的最後採用三組不同色溫光源(0K、3000K與6000K)與兩種不同節奏音樂(fast與slow),交互搭配做探討,觀察光源結合音樂對警覺度的影響。實驗結果發現當光源色溫差不同時,其光源與音樂各自對警覺度影響效果的強度也有所不同。
Many researches indicated that changing correlated color temperature (CCT) or circadian to photometry ratio (c/p value) of lighting condition increases arousal level. However, what is the CCT increases for a given CCT to significantly increase the arousal level. In this experiment, each of 10 different CCTs (TA) having 325 ± 50 lux at subject’s eye level is increased to TM, where TM means the CCT induced significantly higher alertness than that induced by TA with p ≈ 0.05 and < 0.05. Using exponential function, interpolation, and c/p values of these 10 lighting conditions, we may estimate the corresponding TM for any given TA not in this experiment. Besides, ten adapted CCT lighting conditions and the corresponding marginal CCT conditions are determined by our experiment from these marginal CCT conditions.
Music has the same influence on increasing the level of arousal, thus, this experiment adopted three different groups of lighting (0K, 3000K, and 6000K) and two types of music with different tempo (fast and slow) to explore their interaction. The result of the experiment shows that music has better effect on increasing arousal level than lighting with CCT increase 3000K; instead, lighting will work better than music with CCT increase 6000K.
