| 摘要 |
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. |
