為了確認LED照明光源對於人的身心反應與工作效率之影響，並瞭解藍光議題相關指標於室內辦公室照明應用的可能性。本論文旨在分析在類辦公室環境中，12名受試者在12種不同的LED照明光源下的工作表現、視覺疲勞程度與嗜睡感受。12種照明光源藉由具有11個通道的光譜可調式LED照明系統，依據2種桌面照度（400 lx、700 lx）、2種相對色溫（4000 K、6000 K）以及3種藍光峰值波長（420 nm、450 nm、475 nm）來設計完成，並帶有12種不同的節律刺激值與藍光傷害權重輻射。本論文使用2017年本實驗室團隊之實驗數據，透過重複測量、成對t檢定、皮爾森相關等統計方式重新分析，驗證照度、相對色溫等實驗變項是否對於受試者的反應有顯著之影響，並比較不同藍光指標之間與受試者反應的相關性。依據本論文之分析結果，4000 K照明下的疲勞程度較6000 K輕微、電腦任務與紙本任務的工作表現均較佳；400 lx照明下的疲勞程度較700 lx輕微、紙本任務工作表現也較佳。因此，在本論文涵蓋之實驗範圍內，選用4000 K（低色溫）與400 lx（一般桌面照度）之辦公室照明可獲致較少的疲勞增幅與較佳的工作表現。藍光傷害權重輻射與視覺疲勞、嗜睡感受均有顯著的低度正相關；而與紙本任務和電腦任務之工作表現均有顯著的低度負相關，表示藍光傷害權重輻射越高，受試者越疲勞、越想睡、工作表現越差。因此我們認為在相同的相對色溫與照度下，選用藍光傷害權重輻射較低的光譜應為較佳的辦公室照明光源選擇。

In this thesis, 12 office lighting conditions were designed in terms of 2-level correlated color temperature (CCT) (4000 K, 6000 K), 2-level illuminance (400 lx, 700 lx) and 3-level blue-light peak wavelength (420 nm, 450 nm, 475 nm) using a tuneable LED lighting system. Eye fatigue, sleepiness and task performances of 12 participants were analysed with variables of lighting condition including CCT, illuminance, blue-light peak wavelength, blue-light hazard weighted radiance, and circadian stimulus. These data were analyzed with repeated measure analysis of variance, paired t test, and Pearson product-moment correlation. There are several responses of human beings are significantly influenced by these variables. It indicates that eye fatigue increases more under 6000 K lighting condition compared to 4000 K. It also indicates that eye fatigue increases more under 700 lx lighting condition compared to 400 lx. Paper-based and computer-based task performances under 4000 K lighting condition are better than 6000 K. Therefore, we conclude the 4000 K / 400 lx office lighting is the best one within our designed lighting conditions. Blue-light hazard weighted radiance affects human being more than circadian stimulus and blue-light peak wavelengthes. Higher blue-light hazard weighted radiance is significantly positive correlated to eye fatigue and sleepiness feeling, and is significantly negative correlated to paper-based and computer-based task performance. Therefore, we conclude that choosing a low blue-light hazard weighted radiance office lighting condition would offer a better office environment with improving task performance and reducing eye fatigue and sleepiness feeling.
