楔型導光器用於配光量測系統之光學特性探討

Abstract

本論文提出了一套新的方式作為快速且低成本量測光源配光曲線的方式，在論文中探討了光線在楔型導光器內行進的光路，並建立光線行進的二維及三維數學模型，推導出入射光線角度與在楔型導光器表面出射位置的對應關係，透過數學模型，我們利用壓克力材料製作一楔型導光器，並且我們利用雷射準直光線在楔型導光器上驗證了數學模型關係的正確性，最後我們利用了此楔型導光器建置了一量測光源配光曲線的實驗平台並量測LED光源。

This thesis presents a new approach to measure luminous intensity distribution curve with a fast and cost-effective way. We investigated the propagation path of an optical wedge guides, and the established a three-dimensional light pipe model with vector-form analysis. We derived the correspondence between the angle of incident light and the position of exit light on the wedge guides surface. By using a collimated laser beam coupling into the wedge transformer, we verified the validity of proposed mathematical model. Finally, we use this wedge transformer to set up an experimental platform to measure the luminous intensity distribution curve of LED successfully.
