本研究之目標是設計以側光光纖發光之紅綠燈。近幾年側光光纖逐漸被光學業者用於裝飾燈、汽車尾燈。但以側光光纖燈條作為紅綠燈光源來設計紅綠燈則尚待研究。本研究透過在光纖表面上使用V型特徵結構的手段，將從光纖一端入射之LED光源因特徵結構破壞其全反射而使光改變方向從側向射出來設計光源。設計方法是先藉由TracePro光學軟體來模擬光線在光纖內傳播情形，並將V形特徵結構與光纖幾何參數化，利用TracePro內的幾何優化器來優化光纖模型使之最佳化。再透過TracePro設計出燈罩、透鏡，使得光從光纖射出時，經由燈罩聚集光線後發出符合CNS14546號誌燈照射規範發光強度及照射範圍。最後將模擬所得之模型建構出來，並依據CNS14546之規範做光強度與輝度之實驗來驗證自己的模擬與優化。
The main purpose of this study is to design a traffic light using side lighting optical fibers. In recent years, the wide use of side-lighting optical fiber in optical industry, as decorative lights, car taillights and so on. Therefore, we use this idea in our traffic light design.
LED is used as a light source and put it at one end of the optical fiber for light incidence. The optical fiber we used for glowing was designed by the rectangular triangle shape at the bottom and the top of the fiber. When the incident light comes to the bottom of the fiber, the light would be reflected and made the light go to the side of the fiber. In our study, we used TracePro optical software to simulate the light path. By the optimization function in TracePro, we use several parameters to control the shape of rectangular triangle in the optical fiber and do some simulation to make optical fiber glowing as bright as possible. Then, we used the same function to design the lamp cover and lens of traffic light and made the traffic light we designed corresponding with requirements of luminous intensity and irradiation range according to CNS No.14546. Finally, we would build the simulation model, and did some experiments to measure the luminous intensity and brightness. By the experiments, we could validate the simulation and optimize our traffic light model.
