路燈的光型現今大部分都以長方形做為設計目標,本論文利用光學軟體Zemax建構出一種分離型光源的反射式路燈模型,這種分離型光源不僅能加速路燈之維修,其利用間接照明之形式也能降低眩光之不適,我們以台灣LED路燈法規作為我們設計之標準,光源採用Cree公司所生產的高功率白光LED(XHP35 High Intensity),以單顆LED搭配一個準直反射罩做為一組光源,利用四組光源以產生準直光線,並將光源置於燈桿內,而自由曲面之設計是以平行光做為入射光設計的,利用映射之方式透過數學軟體Matlab計算出自由曲面的節點,再匯入至Zemax形成反射面,當平行光入射至切割點(800x800)之自由曲面上,其能有效地將光線反射至路面上形成均勻的長方形光型,而利用四組光源產生之準直光,其具有些微的發散角,使光線透過切割點(400x400)之自由曲面反射至路面時呈現梯形光型,路燈規格之參數以間隔27米、桿高6米、照明面積25x10m2,從光源到達路面的效率為0.94、平均照度20.6 lx、照度均勻度0.816。
A great streetlight can achieve rectangle light pattern and good uniformity on road way. Through Zemax can build the reflective freeform streetlight based on split light source. The split light source can make more efficiency to maintain streetlight when malfunction. And we comply with the regulation of street light of Taiwan(CNS 15233) to design reflective street light. The light source can produce collimating light from LED(Cree Xlamp XHP35HI) and parabola mirror(collimating reflector). We use the method of mapping to find the points of freeform surface on Matlab. Finally, the light pattern is like trapezoid and its area is about 25x10m2 for single streetlight. The average illuminance is 20.6 lx and uniformity can reach 0.816.
