摘要(中)

本論文中，我們將研究不同的白光LED 封裝型式其在空間上色彩均勻性的差異。我們將利用已建立之YAG 螢光粉模型，在相同色溫下分析各種封裝型式的空間色偏。
接著針對特定封裝形式，藉由改變其封裝體外型，在固定整體色溫下有效降低該封裝形式之空間色偏，亦即增加其空間上的色彩均勻性。
最後，再分析不同封裝形式在中場範圍內空間色偏的表現與定義其色彩之準遠場距離。

摘要(英)

In this thesis, we study color uniformity of white light LEDs with different package types. Based on the YAG phosphor model, we analyze the angular correlated color temperature deviation (ACCTD) for white light LEDs with different package types and find out which one is lowest.
After that, we modify the ACCTD of specific package types with the same correlated color temperature by changing the structure of the package. Finally, we study the ACCTD changes in mid-field region for white light LEDs and
define the distance of quasi far-field in color.
