Abstract

Methods by which the correlated color temperature and the distribution temperature of a light source may be calculated from a knowledge of the spectral power distribution of the source are described. Digital-computer programs have been written to perform the calculations; these programs are described, with the results of some tests for a number of sources. The two temperatures are significantly different for some sources. A new concept, “daylight distribution temperature” is also introduced and some examples are given.

  1. The definition given in the current (May 1968) draft of the 3rd edition of the International Lighting Vocabulary is: "Temperature of the full radiator for which the ordinates of the spectral distribution curve of its radiance are proportional (or approximately so), in the visible region, to those of the distribution curve of the radiation considered. Note: Both radiations will necessarily have the same, or nearly the same chromaticity."
