Abstract:	本論文主要是根據實際的道路標準，利用一Lambertian分布的LED光源，設計一燈具使用單側布置能應用在十米寬的道路照明上。用光學模擬軟體LightTools建構反射罩模型並做光追跡獲得配光曲線，並利用照明計算軟體Dialux來分析照明結果。模擬結果平均照度為23 lx，平均輝度1.5 cd/m2，縱向均勻度、照度均勻度、輝度均勻度、最低門檻增量分別為0.73、0.519、0.4、8 %皆可符合CJJ 45-2006主要道路的照明規範。We designed a luminaire which utilize LED light source in the Lambertian distribution according to the practical standard of the road illumination. The luminaire is placed on single side of a 10 m wide road. We constructed a reflector and simulated the intensity distribution curve of luminaire by LightTools, and analyzed the results of illumination by Dialux. The average illuminance of simulated demonstration is about 23 lx, the average luminance is 1.5 cd/m2, and the value of longitudinal uniformity, uniformity of illuminance, overall uniformity, and threshold increment are 0.73, 0.519, 0.4 and 8 respectively, wherein the values conform to the standard of major road illumination of CJJ 45-2006.
