Abstract

Vorgestellt wird eine Kraftfahrzeugbeleuchtungseinrichtung (100) mit einer integrierten Leuchte (14), die eine Lichtquelle (34) und ein optisches Element (36) aufweist, das dazu eingerichtet ist, Licht der Lichtquelle (34) zu sammeln und über eine Lichtaustrittsfläche abzustrahlen, sowie mit Strukturen (22, 26), die eine Ausbreitung des von dem optischen Element durch die Lichtaustrittsfläche ausgehenden Lichtstroms in bestimmte Raumwinkelbereiche (42, 44) versperren. Die Kraftfahrzeugbeleuchtungseinrichtung (100) zeichnet sich durch wenigstens einen Lichtleiter (102) aus, der einen ersten, vergleichsweise kleineren Teilbereich der Lichtaustrittsfläche des optischen Elements (36) mit einer Licht einkoppelnden Fläche (104) des Lichtleiters (102) abdeckt, einen zweiten, vergleichsweise größeren Teilbereich der Lichtaustrittsfläche freilässt, wobei der Lichtleiter (102) dazu eingerichtet ist, über die Licht einkoppelnde Fläche (104) eingekoppeltes Licht an den Strukturen (22, 26) vorbei zu leiten und über eine Licht auskoppelnde Fläche (111) des Lichtleiters (102) in die bestimmten Raumwinkelbereiche (42, 44) abzustrahlen.

A motor vehicle lighting device (100) is presented with an integrated light (14) which has a light source (34) and an optical element (36) which is arranged to collect light from the light source (34) and to radiate it via a light exit surface, and with structures (22, 26) which obstruct a propagation of the luminous flux emanating from the optical element through the light exit surface into certain solid angle regions (42, 44). The motor vehicle lighting device (100) is characterized by at least one light guide (102), which covers a first, comparatively smaller portion of the light exit surface of the optical element (36) with a light coupling surface (104) of the light guide (102), a second, comparatively leaves larger portion of the light exit surface, wherein the light guide (102) is adapted to lead via the light coupling surface (104) coupled light past the structures (22, 26) and over a light coupling out surface (111) of the light guide (102 ) into the determined solid angle ranges (42, 44).
