在導光板下表面採用擴散點並搭配兩片正交擺放之3M ”BEFⅡ 90/50” 增亮膜,發光區域之正視角平均輝度可達到11110(nit),且均齊度達到90.06%,且導光板之厚度約為1(mm)。

A novel type of extendable bottom lighting LED light guide plate is proposed and designed in this thesis. An extendable unit, an embedded LED and a cone bottom are used to achieve a characteristic of high utility and low thickness. The most particular part in this study is the design of the cone bottom which could directly modify the intensity profile of LED in order to obtain high uniformity. With the help of optical design and simulation tool called SPEOS, this new type emitting unit can reach high uniformity and luminance. The extendable characteristic of this thin and high performance bottom-emitting LED light guide unit could provide wide applications in the future lighting and LCD backlight module markets, at the same time conforms the conception of thin light guide plate.
The final product provides 90.06% uniformity and 11110 nit luminance with the two BEFs. The thickness of light guide plate is 1 mm.
