本論文主要目的是利用TracePro光學模擬軟體優化無光害LED路燈之設計、分析與驗證的結果。利用以往論文與實驗室研究所得的成果截長補短再做更進一步的優化、驗證與研究。應用以往論文田口實驗計畫法的直交表設定各項參數優化後的結果;本論文之無光害LED路燈採用:導光管管徑粗細為20mm、導光管材質為PMMA、燈杯和導光管間距為0.08mm、導光管兩側切角為0°、導光管各面有AR Coating、導光管與反射面的距離為0.1mm等可控制因子做參數設計。將導光管內反射層傾斜26°~36°,路燈距地面高度4.4m~5.8m;利用TracePro光學模擬軟體進行模擬,取得反射層與路面最大照度所需的角度,再配合現行設置LED路燈技術規範的路面寬度與路燈間距進行模擬,得到的照度均勻度與平均照度的模擬結果是否能夠符合現行LED路燈性能規範與設置LED路燈技術規範的要求。所得到的無光害LED路燈,模擬所得到的平均照度為20.24Lux、符合快速道路、主要道路平均照度須大於15Lux的要求。而且無光害LED路燈整體均勻度佳,所得到的照度均勻度為0.44、符合LED路燈性能規範(≧0.33)的要求;與傳統8m高LED路燈相較不會有兩路燈間距中間較暗的缺點。且在距離路高18m處設置一24mX8m的觀測面所得到平均照度(光害)均較傳統LED路燈降低了38.71%的光害。故本論文所設計之無光害LED路燈不但平均照度與照度均勻度符合現行規範,而且在照度均勻度與光害的抑制上均較傳統LED路燈優異。The purpose of this paper is to use the TracePro optical simulation software to optimize design and analysis the none light pollution LED street lighting.Using the research result by Taguchi method previously,we got the best combination of parameters such as the diameter of tube is 20mm、the material from plastic of tube is PMMA、light cup and lamp spacing is 0.08mm、tube cutting angle on both sides is 0°、the gap between the tube and reflective surface is 0.1mm、tube surface property with AR coating。Rotated the reflective surface angle of tube around 26° to 36°,the height of lamp from road around 4.4m to 5.8m;Using the TracePro optical simulation software to get the optimization average illuminance、illuminance uniformity from the road if can meet the official rule and specification。After simulation,the best average illuminance is 20.24Lux (Over the specification:15Lux on the high way)and the illuminance uniformity is 0.44(Over the specification≧0.33)and better than tradition LED street lighting。The none light pollution LED street lighting not only have the better illuminance uniformity than tradition LED street lighting but also reduce the light pollution around 38.71%compare with tradition LED street lighting。Our design of the none light pollution LED street lighting not only have the better illuminance uniformity than tradition LED street lighting and meet the official rule and specification but also reduce the light pollution more better than tradition LED street lighting。
