固態照明光源非常有潛力成為下一世代的主要照明光源，而光源顯示色彩的能力是相當重要的，尤其人工自然光源(daylight)的製作不僅是對於照明光源之應用，且在校正標準光源等應用，更具其重要性。本論文主要是透過製鍍固定式多層膜干涉濾光片來校正數顆Light Emitting Diodes （LEDs）的混成光源，以期達到彈性調整不同色溫（可調色溫範圍4,000K到10,000K）之自然日光的模擬，藉由與自然日光光譜相近而模擬出自然日光光源。文中將詳細介紹此自然日光模擬光源的製作方式，以及其實際量測結果。

Recently, solid state lighting plays as an important role in a novel colorimetric instrumentation. LEDs are being further evaluated as one of the possible standard light sources. In this work, an innovative tunable daylight simulator is developed, which mainly consists of only few LEDs plus one special designed optical thin- film filter with fixed transmission spectrum. This tunable daylight simulator does simulate daylight of correlated color temperature (CCT) ranged widely from 4,000K to 10,000K. The design and the experimental measurement will be reported in details.
