Abstract:	摘要本論文主要目的是選用一種防眩光之燈具作為路燈配置，利用光學模擬軟體 TracePro進行模擬、設計以及分析，並利用田口實驗計畫法，設定各項參數，優化其結果。本論文之防光害LED光管分由散熱半管、LED光源及燈罩3部分組成，其管徑12公分、長120公分，LED晶片置於散熱半管上，燈罩材質為PMMA。用其作為路燈，以側打方式進行配置，降低由地面反射之多餘雜散光，以達到減少光害的目的。參數最佳化後為：架設高度20公分，與路面中心之距為5公尺，轉動角度為88.3度，總功率130.9瓦(10支防光害LED光管)，用於8公尺路寬，在24公尺內取代2支傳統LED路燈(約146瓦)，最後路面平均照度為17.457勒克斯，照度均勻度為0.64，天空12公尺處的照度為傳統的5.81%；天空18公尺處的照度為傳統的4.16%。 Abstract The study is for reducing light pollution with a kind of anti-glare lamp for configuration of street lighting. Simulate, design and analyze by TracePro, and optimize the parameters by Taguchi method. The chosen anti-glare lamp is called anti-glare LED light bar, and is configured by three parts: heat half pipe, LED source and lamp. The light bar’s radius is 6 centimeter, length is 120 centimeter, LED chips are mounted on the heat half pipe and the material of lamp is PMMA. As street lighting, it reduces the redundant light reflected from road in the night sky by side lighting. The optimized parameters: setting at 1 meter height, 5 meter from the center of road, rotating 88.3 degree. The simulated result: replace 2 traditional street lighting (146 watt) by 10 light bars (130.9 watt) in the road of 8 meter wide and 24 meter long. Of the road, the average illuminance is 17.457 lux, the uniformity ratio of illuminance is 0.64. The average illuminance in the 12 meter high sky is 5.81% of traditional street lighting in the 18 meter high sky is 4.16%.
