LIGHT SOURCE EMITTING MIXED-COLORED LIGHT AND METHOD FOR CONTROLLING THE COLOR LOCUS OF SUCH A LIGHT SOURCE

摘要

A light source (10) is disclosed, emitting multi-coloured light with light of at least two different colours, emitted from a number of primary light sources (1) wherein the primary light sources (1) are divided into groups and the brightness values of the primary light sources (1) within a group are determined and controlled separately according to colour, such that the colour location of the multi-coloured light lies in a given region of the CIE standard colour diagram. The invention further relates to a method for controlling such a light source (10) and an illumination device with such a light source (10), for example, for backlighting a display.
