本論文提出了一套高效率光學耦合器設計方法，可用於收集多個光源進行壓縮並且統整成一個光源出口。它採用拋物面共焦原理和高反射率鍍膜，並用公式化的概念完成結構設計。光學耦合器除了可直接收集太陽光之外，也針對Natural Light Illumination System (NLIS) 集光子系統的出口光源進行耦合。NLIS的概念是收集太陽光並直接導入室內照明。由於集光子系統之光源出口眾多且非平行光，對於空間利用及後端傳輸不便，因此考慮實際NLIS結構做耦合器的改善，以維持本設計的效率。
本研究模擬採用的光學軟體為Fred。耦合900個光源時仍保有50.28%的耦合效率。並且結果顯示此光學耦合器在應用上可提供完善的使用方式，也解決了出口問題，最終達到高效率耦合。

This study proposes a set of high-efficiency optical coupler design methods that can be used to collect multiple light sources for compression and integrate them into one light source outlet. It adopts parabolic confocal principle and high reflectivity coating and completes the structural design with the formulation concept. In addition to direct sunlight collection, the optical coupler is also coupled to the exit source of the collection subsystem of natural light illumination system(NLIS). The concept of NLIS is to collect sunlight and direct it into indoor lighting. Due to the numerous light sources and non-parallel light exiting from the light collection subsystem, it is inconvenient for space utilization and back-end transmission. Therefore, the actual NLIS structure is considered as a coupler to improve the efficiency of this design.
The optical software used in this study was Fred. Finally, coupling 900 light sources still maintains 50.28% coupler efficiency. The results show that this optical coupler can provide perfect use in application, and also solve the export problem, and finally achieve high coupler efficiency.
