本論文以表面結構擴散片為主要元件，設計出一款能適應在曲線道路照明並減少光害及能量損失的路燈照明模組為目標，並探討如何將光能有效地控制並集中照射在曲線道路之目標區域內，而在實際應用上，該LED路燈照明模組只需藉由更換不同擴散片的方式來適應用於不同的曲線道路上，即能達到道路照明之效果，在模擬設計方面，根據國際照明委員會 CIE 與 IESNA 擬定之法規標準，我們以一實際的曲線道路做為照射目標區域，並以燈桿高度為12 m 的情形下，獲得中心照度為 17 lx且光學利用率為 53.79 % 之光學特性，最後製作出實際表面微結構擴散片進行分析與模擬做一驗證。;In this thesis, we proposed a lighting module of the adaptive streetlight with surface-structured diffuser. By using the proposed lighting module, the light can be effectively focused on the target region of curved roadway to reduce the light pollution and energy loss. Besides, in the practical application of the proposed lighting module, different adaptive light patterns on the different curved roadways can be easily obtained by replacing the corresponding surface-structured diffuser. Based on CIE and IESNA regulations, we adopted simulation analyses. Under a mounting height of 12 m, the lighting module can perform the excellent effects that the central illuminance is 17 lx and the optical utilization factor is 53.79% on the target region. Finally, we manufactured an real prototype of surface-structured diffuser to perform the related measurement analyses and compare with the simulation results as a demonstration.
