人們大部分時間都待在室內辦公、娛樂，然而曝露在室內照明的時間比室外照明長，生理時鐘容易位移，使得有些人會出現熬夜的現象，間接產生難以入睡甚至產生負面情緒影響。本論文探討在夜間時段曝光 30 分鐘的光源下，會產生的心理情緒反應以及嗜睡程度。12 種組合光源由 2 種色溫（4000 K、6000 K）、2 種照度（400 lx、600 lx）和 3 種藍光峰值（420 nm、450 nm、475 nm）組成，利用具有可調節之多種通道 LED 照明系統並搭配光譜式量測儀器設計光源，接著將光源數種量測數據導入 Mark S. Rea 提議的第 2 代節律刺激指標模式（CSt, f）中，所計算出來的節律刺激值（CS），即代表光源抑制褪黑激素的程度。實驗後會使用符號檢定個別比較色溫、照度和藍光峰值條件下 10 種情感詞彙的顯
著差異，接著透過主成分分析將 10 種情感詞彙分類成 2 個主成分並當作依變數進行線性迴歸分析的模型建立。另外，本論文把受試者給予 10 種情感詞彙的評價分數以等高線繪製在克氏曲線中，建立出類克氏曲線的情感地圖。最後透過皮爾森相關分析和 95% 信賴區間觀察受試者在 12 種光源下給予的嗜睡評價分數及發展趨勢。根據本論文分析指出，低色溫 4000 K 更能讓人感到放鬆且比較舒適，高照度 600 lx 比較不使人感到壓迫感；卡羅連斯加嗜睡評價分數與 CS 值和色溫皆呈負相關，與照度則沒有明顯的相關性，由此可見 CS 值和色溫更能影響嗜睡程度，也就是說若睡眠前的室內照明採用低色溫且 CS < 0.3 的光源，不僅能明顯感受到放鬆、舒適及壓迫感低，也能使人更容易感覺睡意。

　　People spend the majority of their time indoors for work and entertainment. However, they are exposed to indoor lighting for longer durations compared to outdoor lighting, leading to potential disruptions in their biological clocks. As a result, some individuals experience difficulties in falling asleep and even negative emotional effects. This study aims to explore the psycho-emotional responses and levels of sleepiness associated with light exposure for 30 minutes prior to sleep. 12 combinations of light sources were used, comprising two color temperatures (4000 K, 6000 K), two levels of illuminance (400 lx, 600 lx), and three blue light peaks (420 nm, 450 nm, 475 nm). The light sources were designed using a LED lighting device contains multi-adjustable Channel and spectral measuring instruments. The measured data were then input into the model of the widely discussed Circadian Stimulus (CSt, f , Mark S. Rea et al, 2021), which represents the light source's suppression levels of melatonin. Following the experiment, the sign test were employed to respectively compare the significant differences in emotional adjectives responses under varying conditions of color temperature, illuminance, and peak wavelength of blue light. Principal Component Analysis were conducted to classify the emotional adjectives into two principal components, which would be served as dependent variables for Linear Regression Analysis. Additionally, this study presented the evaluation scores of the 10 emotional adjectives given by the subjects on Kruithof Curve with contour lines, thus establishing an emotional map similar to the rule of Kruithof Curve. Finally, Pearson Correlation Analysis, along with a 95% confidence interval, were used to observe the sleepiness evaluation scores and their development trends given by the subjects for each of the 12 light sources. The analysis of this study highlighted
that a low color temperature of 4000 K induced a sense of relaxation and comfort, while a high illuminance of 600 lx reduced feelings of pressure. Furthermore, the Karolinska sleepiness evaluation score exhibited a negative correlation with the CS value and color temperature, while showing no significant correlation with illuminance. Thus, it can be inferred that the CS value and color temperature have a greater impact on the level of sleepiness. In other words, the adoption of a light source with a low color temperature and CS < 0.3 for indoor lighting before bedtime not only promotes a relaxed and comfortable environment but also facilitates easier sleep onset by alleviating pressure.
