| Summary: | 碩士 === 中原大學 === 室內設計研究所 === 98 === The indoor lighting, in the nowadays society, plays the role getting more and more important, which is no longer limited to the illumination, but molds atmosphere in spaces. The color temperature and the color rendering index of light affect people a lot to the color sensation and the colored effect. Although indoor lighting has developed more than 100 years, it still has disparity with sunlight, especially the color effect, of most needed, has to improve. This research is improving the color effect significantly in the indoor lighting by glass filter adjustment. The conclusions is that the color, which was the source for the modified forecast sample, was better than the original light source. They are halogen added blue glass with Glass005, the CRI raised to 88; LED with Brown001, CRI raised to 94.31, and the other set of LED with Glass002 which Ra value is 95.10. In addition, in a double LED light transmission devices and partly with Blue004 & Green002 CRI upgraded its 95.99.
