摘 要：JJG 211—2005亮度計檢定規程已頒布實施，它同時囊括了亮度計和彩色亮度計的檢定，增加了光源色度參數的校準。在實施實踐中，校準彩色亮度計所用的標準反射色板采用了色差計校準用的一套標準反射色板，校準時的標準值取標準反射色板溯源證書中的A/2，0/45的數據。從彩色亮度計中光源色度參數的實驗數據，以及對其測量結果的不確定度分析，均證明新規程校準方法正確，而共用標準反射色板亦可行，校準效果良好。
關鍵詞：彩色亮度計；光源色度；校準；標準反射色板；檢定規程；色差計；不確定度

Abstract： National verification regulation for luminance meter， JJG 211-2005 was published and implemented. This regulation was used to verify either luminance meter or color one， and calibration of illuminant chromaticity was required. During color luminance meter calibrating， its standard reflection shade guide was the same as that for colorimeter calibration， and these standard values A/2，0/45 according to certificate of standard reflection shade guide were used. It is proved that method of this new verification regulation is correct， standard reflection shade guide for colorimeter calibration could be used in color luminance meter calibration， and its calibration results is very well according to experimental data of illuminant chromaticity parameters for color luminance meter and measurement uncertainty.
Key words： Color luminance meter； Illuminant chromaticity； Calibration； Standard reflection shade guide； Verification regulation； Colorimeter； Uncertainty
