普通照明用LED显色性评价

Assessing the Color Rendering of LEDs for General Illumination

物体在LED光源照明下的颜色质量是普通照明用LED的1个非常重要的参数,CIE显色指数(CRI)是目前唯一国际公认的评价光源显色性的方法。但是近期LED光源的视觉试验表明显色指数(CRI)计算结果与实际视觉实验结果之间存在冲突。本文主要分析了目前LED显色性评价的情况。

The quality of object color under LEDs for general illumination is an important aspect of the value of the LED light source. CIE color rendering index(CRI) is the only internationally-accepted method for assessing the color rendering performance of light sources. But the recent visual experiments on LED light sources have shown that the result of color rendering index(CRI) contradicts the visual experience. This paper makes an analysis on the status of assessing the color rendering of LEDs.
