近年來，隨著資訊教學系統的發展，數位化教學已非常普遍，臺灣各層級的學校教室幾乎都配備了投影機、螢幕等硬體設備，還有些智慧教室使用互動式電子白板，對於教室照明應該要有更嚴格的要求，然而目前對於這些新型態教室的照明設計，還停留在傳統教室規範，因此本研究想嘗試不同以往的教室照明規劃，建立更適合未來智慧教室的照明環境。

本論文以國立臺灣科技大學的學生為調查對象，在經常使用投影簡報上課的教室進行投影幕視覺舒適度實驗，目的是要調查學生們上課時，偏好的投影幕顯示輝度值。接著以教室燈具開關數量作為自變項，受測者的主觀問卷回答作為應變項，進行變異數分析，結果顯示當教室燈具關閉前兩排燈、關閉前三排燈、關閉前四排燈時，受測者有較低的視覺疲勞感及較高的滿意度，與其他燈光控制 場景有顯著差異。再以輝度計、照度計量測各燈光場景的投影幕顯示輝度及座位區平均照度。

根據量測數據，再以DIALux模擬一個全使用非對稱配光燈具的教室照明環境，目的是將投影幕的顯示輝度 控制在受測者體感舒適的範圍內，而座位區平均照度希望能達 500 lux。最終模擬結果顯示，本研究所使用的 A60 LED非對稱配光燈具 若以現今節能LED燈泡的基準效率 120 lm/W進行模擬，光通量可提升至1980 lm，即 可實現投影幕畫面輝度舒適且座位區能維持光亮環境的目標。待未來真正改善發光效率及優化眩光問題，非對稱配光燈具有潛力於教室照明規劃中使用 。

In recent years, with the development of information teaching system, digital teaching has become very common. Almost all school classrooms at all levels in Taiwan are equipped with hardware devices such as projectors and monitors, and some smart classrooms use interactive electronic whiteboards, which should have more strict requirements for classroom lighting, however, the current lighting design for these new classrooms is still stuck in traditional classroom standards, so this thesis would like to study a different classroom lighting plan to establish a more suitable lighting environment for future smart classrooms.

The purpose of this thesis is to investigate the preferred brightness of the projection screen in classrooms where students frequently use projection presentations. Then, the number of luminaires turned on and off in the classroom was used as the independent variable, and the subjective questionnaire responses of the respondents were used as the respondent variable to conduct the variance analysis. The results showed that when the classroom luminaires were turned off from the first two rows to the first four rows, the subjects had lower visual fatigue and higher satisfaction level, and the difference with other lighting control scenes reached significant difference.

Based on the measurement data, DIALux was used to simulate a classroom lighting environment with all asymmetric luminaires, with the aim of controlling the display luminance of the projection screen to a comfortable level for the subject and the average illumination of the seating area to 500 lux. The final simulation results show that if the A60 LED asymmetric luminaires used in this study are simulated with the benchmark efficiency of today's energy-saving LED bulbs of 120 lm/W, the luminous flux can be increased to 1980 lm, which can achieve the goal of comfortable luminance of the projection screen and a bright environment in the seating area. Asymmetrical luminous distribution has potential for classroom lighting planning, pending real improvements in luminous efficiency and minimization of glare in the future.
