摘要

LED燈具低耗能高色彩表現的特點，成為新時代的指標性照明產品，在一般照明與藝術光源領域受到廣泛的應用，如展演舞台的聲光效果或繪畫、攝影等藝文展覽之環境氛圍營造等。而LED燈具在電腦編輯與光源輸出的過程中，如何讓使用者得以精準的控制LED燈具的色光變化，是個值得討論的議題。本研究利用數位相機與LCD上常見的線性轉換校正法，嘗試對LED燈具色光進行校正，並建立一套有效的校正與管理模式。

並列摘要

LED is widely used in illumination of office, commercial exhibition, histrionics and indoor space. It is necessary for the users to understand the actual color properties of the LED light before further deploying them into various applications where high precision color handling is demanded. This study looks into the color characteristics of an off-the-shelf LED lamp. A non-linear correction model was then used to calibrate the color of the LED light. The results indicate the possibility to better manage the color of the LED light.
