本研究探討LED結合六面體反射型燈具為基礎進行道路照明設計，利用反射板產生的反射角度分布，運行配光曲線最佳化，提升燈具橫跨道路的照度均勻性，實現高性能的道路照明。本文利用幾何光學進行光線追跡法分析，根據結果修正模型的導光結構，追求均勻性的同時兼顧光利用率，經數值分析後，整體道路均勻性可高達0.72、燈具正下方橫跨道路之照度均勻性為0.84。

We propose a street lighting design consisting of a cluster LED and hexahedral reflective lamps. The light intensity distribution curves of the proposed luminaire are optimized by reflecting light with proper slant reflector. The numerical simulation results show good uniformity illumination on the street area. The overall illuminance uniformity is about 0.72, and the transverse uniformity under the luminaire is about 0.84.
