本論文利用平面導光板架構設計了兩個非成像光學元件:無漏光之鋸齒狀平面型導光板太陽能集光器及具有均勻輝度的發光條背光模組之設計。在太陽能集光器的設計中,主要的設計想法為利用導光板楔形結構與微結構的配置搭配出一平行區域,使得光線能夠順利經由導光板傳遞至出光表面。本論文最終提出一太陽能集光器設計可達到無漏光且集光比為2300倍。而在發光條背光模組設計中,主要的設計想法為提出了一個微凹盤微結構搭配邊光式背光模組,此微凹盤微結構來改善了以往發光條底部漏光之問題,同時,將此類發光條應用於背光模組中可簡化增亮膜片的使用而可節省成本,本論文最終提出一大型背光模組,可達到縱軸可視角度為70度、橫軸可視角度為100度、輝度94.78%。
This thesis gives two non-imaging optical designs using the planar lightguide structure. One design is a ray-leakage-free sawtooth-shape planar lightguide solar concentrator, and the other one is a lighting-bar backlight modules with uniform luminance.
The key concept of the design of solar concentrator is guiding ray in the lightguide by the parallel boundary that constructed by the suitable arrangement of the micro dimpled structure with the sawtooth-shape boundary of the lightguide. With the design concept, this thesis gives a ray-leakage-free solar concentrator with 2300x- geometrical concentration ratio.
The key concept of the design of lighting-bar backlight modules is using a lighting-bar with dimple-plate structures in the backlight modules. The dimple-plate structure successfully prevents the terrible common ray leakages of the lighting-bar bottom. At the same time, the proposed lighting-bar backlight modules can reduce the module cost, since it can achieve luminance standard without using brightness enhancement films. With the lighting-bar design, this thesis provides a design of large thin lighting-box, which processing vertical viewing angle of 70 degrees, lateral viewing angle of 100 degrees, and luminance uniformity of 94.78%
