Abstract

Die Erfindung betrifft eine Beleuchtungseinrichtung (1) zum Einsatz in einem Kraftfahrzeug. Die Beleuchtungseinrichtung (1) umfasst eine Lichtquelle (12) zum Aussenden von Licht; ein Lichtleiterelement (8) mit einer Lichteintrittsfläche (11) zum Einkoppeln des ausgesandten Lichts, einer Lichtaustrittsfläche (19; 19') zum Auskoppeln des eingekoppelten Lichts, und einer Lichtauskoppelfläche (22; 22') mit Auskoppelelementen (23; 23') zum Umlenken des eingekoppelten Lichts auf die Lichtaustrittsfläche (19; 19'), und ein Streuelement im Strahlengang (20; 32) des durch die Lichtaustrittsfläche (19; 19') ausgekoppelten Lichts. Um eine möglichst homogen ausgeleuchtete Fläche nahezu beliebiger Ausgestaltung realisieren zu können, wird vorgeschlagen, dass das Streuelement eine mattierte Scheibe (9; 9') umfasst, die in einem Abstand (10; 10') zu der Lichtaustrittsfläche (19; 19') des Lichtleiterelements (8) angeordnet ist.

The invention relates to a lighting device (1) for use in a motor vehicle. The illumination device (1) comprises a light source (12) for emitting light; a light guide element (8) with a light entry surface (11) for coupling in the emitted light, a light exit surface (19; 19 ') for decoupling the coupled light, and a light output surface (22; 22') with decoupling elements (23; 23 ') for redirecting of the coupled-in light onto the light exit surface (19, 19 '), and a scattering element in the beam path (20, 32) of the light coupled out by the light exit surface (19, 19'). In order to be able to realize a surface of almost any desired embodiment which is illuminated as homogeneously as possible, it is proposed that the scattering element comprises a matted disc (9, 9 ') at a distance (10, 10') from the light exit surface (19, 19 ') of the Light guide element (8) is arranged.
