本論文在研究與比較高功率白光LED在封裝上以半球螢光粉塗佈方式來封裝,以及一般的平面螢光粉塗佈方式LED，兩者在光學設計上的不同與優劣。另外我們將以etendue的理論來分析其被收光的能力，同時設計不同的TIR透鏡以及CPC一階封裝透鏡來進行收光和整光的工作，驗證其被收光及整光的可能性。

In this thesis, we study the characteristic of the etendue for different packages of white LEDs. We compare the etendue of the package with the phosphor formed in a plan structure and the half-ball one. We study the optical efficiency of the second optics such as TIR''s for both cases. Finally, we design a compound parabolic concentractor to serve as the first optics. The optical efficiency and the result of beam shaping by the CPC is analyzed.
