Abstract:
A light source (10) is disclosed, emitting multi-colored light with light of at least two different colors, 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 color, such that the color location of the multi-colored light lies in a given region of the CIE standard color 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.
