本研究為應用於LED路燈之非對稱光分佈自由曲面透鏡設計與分析。道路照明要求路燈的二次光學設計在路面為明暗均勻性良好的矩形光斑。本研究以發光二極體作為光源，根據光源的輻射特性與目標區的照度分佈要求適當分配能量。根據單曲面迭代計算法設計透鏡不同剖面的形狀。最後進行模擬與分析，實現結果皆優於中華民國道路照明與能源之星法規之設計。The purpose of this study is talking about the design and analysis of the asymmetric light distribution freeform lens for LED streetlight. Roadway illumination requires the secondary optics design of the streetlight to have a rectangular facular with good uniformity on the roadway. This research use the light emitting diode as the light source. According to the radiation characteristics of the light source and lighting requirements of illumination distribution, the energy of the light source is distributed in the target appropriately. The different profiles of the lens was designed according to the single surface iterative method. Finally, simulating and analyzing the design result. The results show that are better than the R.O.C road lighting regulations and energy star regulations.
