摘要
本文提出一個以圓錐曲面設計多顆LED 來通過光纖管之入光發射器，此模組主要功能是將多顆LED 所發射的光線以匯聚至一點並利用反射以平行光傳輸進入光纖管來改善光線輸出。 主要結構由全反射面以及折射面所組成，其前方加入多顆LED光源來加強光強度。其中在模組中間製作一個斜面進行光全反射面至最外層的拋物全反射面，使光線均勻打出平行光。之後在光源發散光最外層的兩旁製作橢圓全反射面以打至模組中間匯聚至一點，再經由此焦點打至上下兩旁的拋物全反射面使光線平行出光，最後於光線中間製作一個透鏡，使光線打至透鏡經過二次折射打出平行光。 接著經過自製模組與TIR 透鏡模組來做光學模擬之光照度圖和光斑圖分析與比較效果，最後以自製模組和無透鏡模組經過光纖管後的光照度圖和光斑圖中可以明顯看出使用此模組進入光纖管可有效改善光線輸出結果。

This thesis presents a fiber-optic light emitter using several LEDs and reflectors based on conical surfaces. The main function of this module is to gather light from several LEDs in one point theoretically and obtain output light parallel to the optical axis of the light emitter by using optical components for reflection. The main structure of the proposed light emitter consists of reflection and refraction surfaces. In the frond end of this light emitter, several LEDs are used to enhance the output intensity of the light emitter. In the middle part of this module, one inclined surface is used to reflect light near the optical axis to the outermost reflection surface and obtain the output light parallel to the optical axis. For light far from the optical axis, one elliptic surface is used to reflect and concentrate the LED light in one point which is the focal point of another parabolic reflector. Therefore, the direction of this part of light can also be parallel to the optical axis. For light very close to the optical axis, one len is used and the direction of this part of light can also be parallel to the optical axis. For comparison, a traditional TIR len is created and then the illumination and spot diagrams of the light exits using a traditional TIR len and the proposed module are observed. Finally, the case for transmitting light through optical fiber by using the proposed light exit is examined, and the illumination and spot diagrams are obtained by using the proposed module with or without lens. From these results, we can conclude that the output of the fiber can be improved by the use of the proposed light exit.
