A number of light-emitting diodes include at least two of the light-emitting diodes suitable for emitting light of different colors during operation. At least one color sensor, during operation, detects the light of at least one of the light-emitting diodes. At least one light-measuring face is illuminated by light of at least one of the light-emitting diodes and reflects and/or scatters at least a portion of this light. The light-emitting diodes and the at least one color sensor are arranged on the mounting surface, the at least one light-measuring face is arranged at a distance from the carrier, and the at least one color sensor; detects for the most part light reflected by the at least one light-measuring face from at least one of the multiplicity of light-emitting diodes.
