摘要

近年來，環保議題逐漸受重視，隨著發光二極體(LED)應用領域不斷的被開發，具有高亮度、體積小、省電效率佳、壽命長及環保等特點，將逐漸有取代傳統光源的趨勢。LED 是由R(紅)、G(綠)、B(藍)三原色所混成的色光，純度高，色彩飽和度越大，可呈現的色彩範圍就越大。本研究將探討染色過之梭織物在D65 及LED6500K 燈源照射下，織物所呈現之色彩的差異，利用Digieye Lai 色彩儀器來做RGB、明度、彩度、色相及色差分析。結果顯示，部分測試布樣在D65 及LED6500K 所呈現的RGB 值趨於相近，D65 之RGB 值大多高於LED6500K，且色差仍然偏大。由15 位辨色能力正常之觀測者，對織物所呈現顏色之偏好結果，得知大多數人仍較偏好D65 燈源照射下所呈現之色彩，原因是感覺色彩較鮮豔、明亮及色彩飽和度較高。

In recent years, environmental issues gradually attention. With LED applications fields constantly being developed, with a high brightness, small size, good power-saving efficiency, long life and environment characteristics, light will be gradually replaced by the trend of traditional light sources. LED is from R(Red), G(Green), B(Blue) color blend of shade is of high purity, greater color saturation, can present the greater range of colors. This study will examine the difference of color staining over the fabrics in the D65 and LED6500K light source irradiation, showing the fabrics, fabrics using Digieye Lai color instrument for RGB, brightness, saturation, hue and color differences analysis. The results showed that some of the test fabrics swatches pretended in D65 and LED6500K, RGB tended to be similar to the RGB of D65. D65 is higher than LED6500K, and the color difference is still too large. Recording to 15 observers still prefer color present in the D65 light source irradiation, because the sense of color is more bright and color saturation also higher.
