本論文主要以道路輝度模擬為主加入了乾燥及潮濕路面,使用餘弦光形的疊加方法,找出可適用於乾燥(ME4a照明等級)及潮濕(MEW4照明等級)路面的路燈配光曲線,並提供優化後找到最低流明下可通過規範的配光曲線。 找到最佳的配光曲線後,再以此配光曲線於路面的等照度線圖為設計方向,在二次光學模擬設計上,可以以此等照度線圖為目標,進而較快速的設計出可通過法規之配光曲線。 本論文中透過此方法為複雜的道路照明光學設計中之光學模擬提供一個新的發展方向。 ;In this thesis, we focus on the simulation of the road luminance for the dry surfaces and the wet surfaces both. By the superposition of multiple cosinusoidal light distributions, the optimal luminance/illuminance distribution can be found out to meet the requirement of the general standards for the dry roads (ME4a lighting level) and the wet roads (MEW4 lighting level). Then, the street lamps can be more easily designed with the guidance of the optimal illuminance distribution. Here, a new and effective procedure has been successfully developed for versatile street lamp lighting design on diverse road surfaces.
