現今的人們的工作時間都非常的長，而工作環境中的照明會在無形之中深深的影響著人們的生理與心理，受到的影響就會表現於工作成效上，因此工作環境的照明非常重要，本研究以雙動態田口法針對辦公室最適化照明進行參數設計。實驗設計中，雙信號因子分別為色溫及照度，控制因子為環境的燈具配置及牆面色彩變化，針對理想機能專注力、視覺疲勞、舒適度及喜好度進行實驗。此外，本研究以腦電圖和心率變異性的生理參數作為非主觀評價，以問卷量表為主觀評價，同時對受測者的生理變化與心理感受進行分析。根據研究結果可以提出二種照明配置：(1)任務取向的照明設計為色溫4000、低照度500lx，搭配燈具配置1，可搭配輔助光源調整照明至色溫5300K、照度700lx。(2)以生理狀態取向的照明設計為環境照度為500lx，工作平面為照度700lx，同時滿足使用者本身的舒適性與習慣。本研究之實驗結果將是一個最佳化的照明參數，這將有助於燈具製造業界的發展，以及對空間燈光的設計有較好的理解和應用。

People today spend many hours a day on work, the lighting of the working environment is very important, its profound impact on the user's physical and psychological, and performance on the effectiveness of the work. In order to improve the above problems, our team using Double-Dynamic Taguchi Methods to conduct experiments of office lighting. About the experimental design, the signal factor is color temperature and illuminance, the control factor is to change the wall color and lighting configuration, and evaluation for the attention, visual fatigue and preference. In addition, the physiological parameters of electroenc phalography and heart rate variability were measured as non-subjective evaluation of this experiment, questionnaire scale as subjective evaluation, and analysis of the physician's physiological changes, psychological feelings at the same time. According to the results of the study, two lighting configurations can be proposed: (1) a lighting design for task, the color temperature 4000, illumination 500lx, with lighting configuration 1, with auxiliary light source to adjust lighting to color temperature 5300K, illumination 700lx. (2) a lighting design for the physiological state, the ambient illumination 500lx, the working plane for the illuminat on 700lx, while meeting the user's own comfort and habits. The experimental results will be a parameter that optimizes the lighting. It will help the development of the lamp manufacture, space lighting design has a better understanding and application.
