Abstract
(DE)
Es wird eine Leuchteneinrichtung für Kraftfahrzeuge bereitgestellt. Diese weist ein primäres Hologramm (11) zum Bereitstellen einer Leuchtfunktion, wenn das primäre Hologramm (11) mit Beleuchtungslicht (14) beleuchtet wird. Das Beleuchtungslicht (14) wird über ein sekundäres Hologrammsystem (12) mit einem Einkoppelhologramm, einem Wellenleitersubstrat und einem Auskoppelhologramm zu dem primären Hologramm (11) gelenkt.
(EN)
The invention relates to a lighting device for motor vehicles. Said lighting device comprises a primary hologram (11) for providing a lighting function when the primary hologram (11) is illuminated with illumination light (14). The illumination light (14) is directed towards the primary hologram (11) via a secondary hologram system (12) which comprises a coupling-in hologram, a waveguide substrate and a coupling-out hologram.
(FR)
L’invention concerne un dispositif d’éclairage de véhicules automobiles. Celui-ci comporte un hologramme primaire (11) destiné à fournir une fonction d’éclairage lorsque l’éclairage de l’hologramme primaire (11) est éclairé (14). La lumière d’éclairage (14) est dirigée vers l’hologramme primaire (11) à l’aide d’un système d’hologramme secondaire (12) comportant un hologramme d’injection, un substrat de guide d’ondes et un hologramme de sortie.
