摘要

LED(Light Emitting Diode)發光二極體於光電發達的世代來說，是一個極具發展性的產業，同時也是重要的綠色能源產業之一，隨著科技的進步，對於LED的發光內容亦有所突破，甚至LED的色彩顯示品質亦受到照明產業的重視。本研究使用實驗法針對「High-power LED」光源進行色光的量測與分析，以了解其照明頻譜與色域表現。High-power LED具有很長的工作壽命，節能且低電壓、安全性高，為可安全觸摸之冷光線，並可依使用需求調整光源強弱與顏色。經由實際測量與分析後，可知(1)彩色LED的色光可藉由壓克力板達到均勻混合的效果，以利量測；(2)High-powerLED的色域範圍、色彩投射強度與反應時間均優於一般的LED；(3)High-powerLED藍紫光的表現比sRGB變化更多，而紅色系與綠色系色光之色域表現則略小於sRGB；(4)High-power LED的照明偏冷色調，適合特殊用途，不適合一般照明或閱讀照片。

LED (Light Emitting Diode) is one of energy-saving and environmental friendlyluminance products. LED products are commonly applied by various of industries nowadays. This study was aimed to measure and analyze color performance of High-power LED, one of the most advanced LED products, to understand its light density, light spectrum and color gamut. After the experiment, the results showed that (1) A white acrylicboard is very useful to mix different LED colors when measuring. (2) The color gamut, light intensity, and reaction time of High-power LED are better than those of regular LEDs. (3) The blue-purplish light performance of Highpower LED is better than that of sRGB color space. Gamuts of both red and green hues of High-power LED are better than those of sRGB. (4) High-power LED is suitable for special purposes but not for regular nor reading luminance.
