Abstract

A light guiding device for an illumination device, especially for a motor vehicle or an indicator device in a rearview device of a motor vehicle includes a light coupling side for incoupling light from a light source, a reflection side having a reflection layer; and a light outcoupling side, which is disposed generally opposite the reflection side. A clearance between the reflection side and the light outcoupling side generally decreases as the distance from the light incoupling side increases. The reflection side having the reflection layer is configured so that light arriving from the light incoupling side is deflected to the light outcoupling side. The reflection layer may be a paint or lacquer layer that is imprinted or evaporation-coated on the reflection side.
