照明是人類的基本需求，由於近年環保意識抬頭，因此相較於傳統光源，發光二極體(LED)省電環保等優點，且發光效率快速成長，未來可望取代傳統光源成為照明光源。而路燈是城市發展中不可或缺的工程，也是交通建設上重要工程之ㄧ，因此本論文利用光學模擬軟體設計合乎國家法規之LED道路照明燈具，進而實現固態照明。
本論文已成功將不同散角之LED光源建立於光學軟體中，並設計垂直與倒V兩種方向之反光模組來達到所需之場形。燈具設計模擬之最佳化結果為散角140∘之LED光源，其與垂直反光板夾角為70∘，倒V反光板角度為(1,18)，其配光曲線圖數據皆符合經濟部能源局所訂定之燈具配光特性。實作之燈具採用散角140∘之LED光源，其與垂直反光板夾角為70∘，倒V反光板角度為(1,15)。所得之發光效率為44.87 lm/W，燈具轉換效率59.1%，模擬與實作之配光曲線圖相關係數高於98.3%。並針對實作路燈進行真實照度模擬，在平均照度為16(lx)，平均輝度0.78(cd/m2)，整體均齊度、縱向均齊度及門檻增量值分別為0.5、0.7及4，對照國際照明委員會(CIE)標準，此設計之LED路燈可應用於次要道路照明。

There is no doubt that lighting is essential to human in the modern life. Because the environmental protection sprouts in recent years, the excellence of LED not only electricity conserves but the luminous efficiency grows rapidly, contributing the tendency that LED will replace the conventional illuminaire in the future. The street lighting is indispensable for the facilities in the developing city and traffic construction. In this thesis, we use the optical simulation software to design the LED lighting lamps that correspond to national legislation in this essay and then achieve solid-state lighting.
It is successful to utilize different diffusion angle of LED to build in optical simulation software. Besides, design of both directions on vertical and Λ-shaped lighting reflection modules to attain the patterns that we need in this essay. The LED simulation optimum view angle of designed lamps is 140,∘ with the angle 70of ∘vertical reflection board and the angle (1,18) of Λ-shaped reflection board. In addition, the data of Luminous Intensity Distribution Curve correspond to the lamp characters of Bureau of Energy, Ministry of Economic Affairs. In reality, the view angle of lamp is 140in LED ∘lighting illuminant, the angle 70∘vertical reflection board, and the angle of Λ-shaped light reflection board is (1,15). The Correlation of simulation and real works is higher than 98.3% at the luminous efficiency 44.87lm/W, with the conversion efficiency up to 59.1%. For the real works of street lightings, the values of Overall Uniformity, Longitudinal Uniformity, and Threshold Increment are 0.5, 0.7, and 4 respectively when performing the real illumination simulation at average illumination 16 lx and average luminance 0.78 cd/ m2. Compare to standards of CIE (Commission International de l'Eclairage), this design can be applied for the lighting of minor roads.
