Abstract
The invention relates to an illumination device for an automobile with at least one light source () to emit light and at least one cup (or bowl)-shaped reflector () to reflect at least a portion of the light emitted by the light source (). The reflector () is formed as a light-conductor structure () with a totally-reflecting reflection surface (). The light-conductor structure () includes at least one light-coupling surface () and at least one light-decoupling surface (). The reflection surface () is formed as a border surface of the light-conductor structure (). It is proposed that either the light-coupling surface () and/or the light-decoupling surface () and/or the reflection surface () of the reflector () include means to deflect the light beams passing through them or reflected by them. Thus, the reflector () can form light radiated from the light source () in conjunction with light-coupling surfaces (), reflection surfaces (), and light-decoupling surfaces () to realize a desired light distribution.
