普朗克轨迹是白炽灯黑体辐射器的颜色随其温度变化在色度空间中的变化路径。它通常绘制在CIE 1931 xy色度图上,呈现为一条从红橙色区域到蓝白色区域的圆弧。它是定义色温的基本参考。

普朗克轨迹是普朗克定律在人类颜色感知框架下的直接图形表示。国际照明委员会 (CIE) 于 1931 年制定了颜色空间标准后,就可以将任何光源的颜色绘制成坐标对 (x, y)。通过计算理想黑体辐射体在约 1000 K 到 10000 K 以上各个温度下的 (x, y) 坐标,并将这些点连接起来,即可形成普朗克轨迹。
This curve is not a straight line. It starts in the deep red part of the diagram at low temperatures, curves up through orange, yellow, and white near the center, and ends in the blue region at very high temperatures. Its significance lies in being the absolute reference for ‘white’ light produced by thermal radiation. Any light source whose chromaticity coordinates fall exactly on this locus has a color temperature equal to the black-body temperature at that point. For sources not on the locus, it serves as the reference for finding the closest point, which defines the correlated color temperature (CCT).
