光谱光度法高精度测定稀土三基色荧光灯色坐标及相关色温

HIGH PRECISION MEASUREMENT OF CHROMATICITY COORDINATES AND CORRELATED COLOR TEMPERATURES OF THREE BAND COLOR FLUORESCENT LAMPS BY SPECTRUM PHOTOMETRY

利用建立起来的计算机及软件系统，控制ＨＲＤ－１双光栅单色仪以１ｎｍ间隔采集３８０～７８０ｕｍ稀土三基色荧光灯的光谱能量分布，用连续积分的计算方法精确测定光源的色坐标及相关色温，测色准确度△ｘ，△ｙ达１０－４量级。证明本测量方法特别适用于含有线状谱气体放电光源的高精度测色。

After acquiring the relative spectral distributions of light sources using computer and software system to control HRD--1 double monochromator,we accurately measured chromaticity coordinates and correlated color temperatures by integral method.The accuracy of △x and △y can reach 10-4 order of magnitude.The experimental result indicates that this method is especially suitable for determining chromaticity and correlated color temperatures of discharge lamp.
