    Abstract: 現今白光LED因其節能優勢已逐漸成為照明世界的主流,但由於其單位面積下的高效輸出與嶄新的光譜,除了為人類帶來前所未有的視覺感受,同時也引起相關人因方面的疑慮。為因應這股新潮流,此論文將以人眼視覺為出發點,再以此為基礎接續照明環境的探討。人眼眼球模型的建構即是此論文首先達到的成果,其幾何與介質參數均採用生物醫學統計資料,並且完成了視覺靈敏度、色差以及散射行為等驗證。為探討虹膜在人眼中所扮演的角色,其反射頻譜接續為研究重點之一。對此,虹膜研究引入了成像系統與共焦系統來作為量測的平台,除了比較兩者之優劣外,也校正出真實虹膜反射頻譜,而其頻譜成果更引入眼球模型做雜散光的分析。
    ;White LED has become one of the most popular luminaires nowadays. However, the high density of lumen output and new spectrum from LEDs not only bring human beings new visual sensations but also safety concerns. In accordance with the new trend, this research starts from the study of human vision and then the interaction with the lighting environment. The human eye model is first constructed in this thesis, where the geometric parameters and refractive indices are adopted from the biometric data. The visual acuity, chromatic dispersion, and ocular scattering behaviors of the eye model are also verified. The iris is then the next topic to analyze its contribution in ocular scattering. The spectral reflectance of iris is measured by an imaging system and a confocal system. The comparisons between the two systems as well as the calibrated spectral reflectance are obtained. Then the iris reflectance is incorporated into the eye model for straylight analysis.
    After knowing well about the visual behaviors, the thesis handles the interaction between the human eye and lighting environment. In the field of outdoor lighting, the thesis first introduces the disability glare formula and the recommendation of road lighting, and then shows some studies such as visual image simulation with glare sources, the influence on visual acuity by varied CCT lighting, and the glare effect from LED-based street lamps. In the field of interior lighting, the thesis introduces the discomfort glare and develops a calculation platform. The studies here include building a transfer function between disability glare and discomfort glare, assessing the discomfort glare of fluorescent lamps and white LED tubes, and revealing their affecting levels to human circadian rhythms. Finally, according to the research outcomes, the thesis is anticipated to contribute the field of human factors lighting.
