Abstract
The invention relates to an illumination device, in particular for vehicles. The illumination device comprises at least two semiconductor light sources which emit light with different colours, as well as at least one light guide into which the light from the semiconductor light sources is injected, and a light mixer device that is arranged on the entry side of the light guide and has a transparent light-refracting element, by which the spatial distribution of the light from the light sources is mixed so as to generate light that constitutes a colour superposition of the light from the semiconductor light sources. The transparent light-refracting element comprises an end face which forms a light entry face for the light emitted by the semiconductor light sources, the semiconductor light sources being arranged next to one another and in front of the light entry face.
