Abstract:

Applied aspects of accounting for the colour non-uniformity of the radiation of LED luminaries (LL), as their technical and operational characteristics, are considered. At the same time, the features of the perception of colour non-uniformity, created by LL in the observer’s field of view on the object, during their long-term operation at different radiation angles in space and on the surface, are shown. The need for a standard that regulates the methodology for assessing colour non-uniformity and the corresponding criteria is indicated. The necessity of including the colour non-uniformity of the radiation of LL in the list of controlled characteristics during the production and operation of these products is shown.
