    • 本論文的目的在研究微形的混光機構，以將RGB LED光源之不同色光均勻混合並於出光口形成一等效白光光源。為此我們提出一個新型的楔形混光機構，並探討其混光均勻度與出光效率。

    In this paper, we study in the small color-mixing elements.Finally, we propose a new color-mixing device,which can transform the RGB light into the white light equivalently,and we verify the color-uniformity and efficiency.
