Chromaticity Difference Specification for Light Sources

TN 001:2014 

 

Chromaticity difference of light sources needs to be specified in many cases, for example for angular colour uniformity, shift of colour during lifetime (colour maintenance) and individual colour variation of products.
This Technical Note gives background information on the subject, presents models for the description of chromaticity differences and gives recommendations for the specification of chromaticity tolerances for light sources.
The publication is written in English, consists of 9 pages with 3 figures and 1 table and is freely downloadable from the CIE webpage.

The following members of DR 2-66 “Colour Difference of Light Sources” took part in the preparation of this Technical Note:

  • Ohno, Y. USA (Chair)
  • Blattner, P. Switzerland
