Abstract

The invention relates to an optical wave guide structure (1) having at least one optical wave guide (2 2 ; 11 12) and at least two light input positions (A... E) each of which is associated with a light source (3 3 ; 4 4 4 ; 22a... e). Said optical wave guide is designed to guide the inputted light and to emit light based on irregularities (6) embodied on the optical wave guide. A control circuit is associated with the light sources (3 3 ; 4 4 4 ; 22a... e) said control circuit being designed to control depending on the time the brightness of the light sources according to predeterminable dimming curves.
