红绿蓝三色LED调色特性的实验研究

Study on the Color Characteristics of RGB LED

摘要: 通过实验,用红绿蓝三色LED匹配出红、绿、蓝、黄、品、青和白等各种典型颜色并测量了各颜色的色度坐标,研究了颜色与LED电流之间的变化规律,用CIE-1931色度图表示出各颜色及颜色调节范围。结果表明,该红绿蓝三色LED可以匹配出大部分实际颜色。

Abstract: In this paper, the typical color such as red, green, blue, yellow, pink, cyan and white is matched using RGB LED, and the chromaticity coordinates are calculated. The variation between the color and the LED current is revealed. The color and color range are showed in CIE-1931 chromaticity diagram. It is found that much of color can been matched using RGB LED.
