摘要
本文探讨了光源色白度与明度、无色彩感和色温等因素的关系。提出了评价光源色白度的公式。对几种典型光源的白度进行了计算，并在ＣＩＥ１９３１色度图上给出了光源色高白度椭圆。建议将白度列为白色光源的色品参数之一。
In this paper we have discussed the relation between the whiteness of the light source and lightness,achromatic stimulus sensation and colour temperature etc. The author give a formula of calculation whiteness on the light source colour,calculated whiteness of some typical light source with this formula,and drawed a elliptical high whiteness region on the CIE 1931 chromaicity dia- gram.
