摘要: 本研究成功設計出可拼接式底面入光導光板發光單元,利用光學模擬軟體SPEOS針對該發光單元進行設計與模擬,使發光單元達到高均齊性與高光利用率。藉由底面入光機制,成功克服傳統側向式背光模組光源擺放位置有限致使總光通量不足之問題,而能提供足夠之光通量,以達到背光模組高輝度之目的。並且藉由其可拼接之特性,能夠廣泛應用於各型尺寸面板背光模組與各式LED固態照明設備,同時亦能發揮其導光板薄型化之特性。 在導光板下表面採用碟形微結構之情況下,搭配一片擴散片與兩片正交擺放之3M ”BEFⅡ 90/50” 增亮膜,發光區域之正視角平均輝度可達到3093(nit),且均齊度達到91.68%。而採用此發光單元之三乘三發光單元群組,其正視角平均輝度亦可達到3128(nit),且輝度均齊度達到92.64%,且最終之整體厚度約為3(mm)。
A new type of extendable bottom-emitting LED light guide plate is proposed and designed in this thesis. With the help of optical design and simulation tool called SPEOS, this new type emitting unit can reach high uniformity and luminance with only 3mm thickness. The final product can have 91.68% uniformity and 3093 nit luminance with the two BEF film. Also the combined 33 units of large area can also achieve 92.64% uniformity and 3128 nit luminance. It is believed that this thin and high performance bottom-emitting LED light guide unit will have wide applications in the future lighting and LCD backlight module markets.
