Abstract

Vorgestellt wird eine Fahrzeugleuchte (10) mit wenigstens einer Lichtleiter-Vorsatzoptik (18), die dazu eingerichtet ist, Licht einer Lichtquelle (16) über eine Lichteinkoppelfläche (22) aufzunehmen und über Lichtauskoppelflächen (24, 26) auszukoppeln, wobei jede Lichtauskoppelfläche (24, 26) über einen Auskoppelarm (28, 30) optisch mit der Lichteinkoppelfläche (22) verbunden ist. Die Fahrzeugleuchte (10) zeichnet sich da durch aus, dass die Vorsatzoptik (18) einen Bereich (32) aufweist, in dem das eingekoppelte Licht gleichmäßig auf die einzelnen Auskoppelarme (28, 30) aufgeteilt wird, wobei die Auskoppelarme (28, 30) mit Lichteintrittsquerschnitten in den genannten Bereich (32) übergehen, deren Größe umgekehrt proportional zur dort herrschenden Lichtstromdichte ist.

Figure imgaf001
A vehicle lamp (10) is provided with at least one optical fiber attachment optics (18) which is adapted to receive light from a light source (16) via a light input surface (22) and to extract it via light output surfaces (24, 26), each light output surface (24 , 26) via a Auskoppelarm (28, 30) is optically connected to the light input surface (22). The vehicle lamp (10) is distinguished by the fact that the attachment optics (18) has a region (32) in which the coupled-in light is divided equally between the individual coupling arms (28, 30), the coupling arms (28, 30) with light entry cross sections in the said area (32) pass, whose size is inversely proportional to the prevailing luminous flux density there.
