高光效LED路燈設計

在本文中，我們提出一嶄新的LED路燈設計，其藉由表面結構擴散片以及二次光學元件的搭配組合，讓光可以有效地集中、侷限並均勻地照射到使用者所需要之目標區域內，以減少能量的損失。將該款路燈照明模組應用至三種在道路上常見的燈桿擺放方式中進行分析，此路燈照明模組可以同時具有高達 87%以上的光學效率、58%至 81%的高光學利用率以及高於北美照明協會法規要求的地面照度均勻度等多重優異表現，並且僅有2%的總能量朝著水平於地面方向或向上輻射至天空，有效地降低了光汙染之生成，此外，與一般LED路燈相比，還可以額外再節省10%至50%的電功率消耗，因此亦具有相當高的節能功效。

In this article, we proposed a novel design of LED streetlight with surface-structured diffuser (SSD) and secondary optical elements. By using the proposed design, light can be effectively concentrated, limited, and uniform illuminated at a target region which we need to reduce the appearance of energy loss problem. Based on the design concept, a lighting module for streetlight is presented and used into three common types of street pole arrangements for the performance analyses of lighting module. According to the simulation results, we can obtain that the optical efficiency of lighting module is higher than 87%, the optical utilization factor is from 58% to 81%, and the illuminance uniformity is higher than the request of IESNA regulation. By using this new module, just 2% of the lamp’s total energy is directed horizontally or upward into the sky, it is good for the reduction of light pollution. Besides, compared with general LED street lamps, the power consumption of the proposed design can be saved with an additional 10% to 50%. An obvious energy-saving effect can be obtained.
