我們利用散射與導光管結合，在設計上走出新道路來。傳統的導光管設計以幾何的角度出發為主，本文則是將散射效應加入導光管中，並且運用DLP投影機與智慧型建築兩個主題來做設計的例子。我們使用具有散射效應的導光管來設計出所需要的設計目標，並且與傳統設計比較，來評斷其優劣。

We suggest that combine light pipe with scattering effect can provide a way for innovative design. Traditionally, light pipe may be designed start at geometry view. In this article, we add scattering effect in light pipe design. We use DLP projector and smart building as two topics of design examples. We design the innovative design by diffusing mechanism and compare it with traditional ones.
