摘　　要：CIE XYZ色度图是颜色工程中关于颜色表示的标准。通过有关CIE RGB与CIE XYZ色度空间转换的分析,以及CIEXYZ色度空间与常用的sRGB色度空间的转换及换算公式,尝试用CIEXYZ色度空间定义的光谱转换为选定色度空间的RGB值,作为LED灯准确输出要求的灯光颜色驱动值。经过对给定波长的光为例进行计算验证,表明CIEXYZ色度空间光谱转换sRGB色度空间的RGB值保证了LED灯显示颜色的精确性。The CIE XYZ chromaticity diagram is a standard for color representation in color engineering.Through the analysis of the conversion between CIE RGB and CIE XYZ color space,as well as the conversion and conversion formula between CIE XYZ color space and commonly used sRGB color space,this paper tries to convert the spectrum defined by CIE XYZ color space into the RGB value of selected color space.The RGB value is used as the driving value of the light color required by the accurate output of the LED light.It takes the light of a given wavelength as an example.After calculating and verifying,it shows that the conversion of the CIE XYZ color space spectrum into RGB value of sRGB color space ensures the accuracy of the color displayed of the LED light.
