Abstract

Vorgestellt wird eine Beleuchtungseinrichtung (1) für ein Kraftfahrzeug mit einer Lichtleiterstruktur (12), die einen flächigen Lichtleiterbereich aufweist, der eine erste breite Seite (18) und eine zweite breite Seite (20) aufweist, die der ersten breiten Seite äquidistant gegenüber liegt, sowie mit schmalen Seiten (22, 24, 26, 28), die die erste breite Seite (18) mit der zweiten breiten Seite (20) verbinden, wobei eine zweite schmale Seite dazu eingerichtet ist, von einer ersten schmalen Seite (22) her auf die zweite schmale Seite (24) einfallendes Licht zu parallelisieren und auf eine dritte schmale Seite (26) zu richten. Die Beleuchtungseinrichtung zeichnet sich dadurch aus, dass die zweite schmale Seite (24) eine erste parallelisierende Teilfläche und eine zweite parallelisierende Teilfläche aufweist, wobei die zweite parallelisierende Teilfläche gegenüber der ersten parallelisierenden Teilfläche stufenförmig in Richtung zum Inneren des flächigen Lichtleiterbereiches versetzt angeordnet ist.

The invention relates to a lighting device (1) for a motor vehicle having a light guide structure (12) which has a planar light guide region which has a first broad side (18) and a second broad side (20) which is equidistant from the first broad side, and narrow sides (22, 24, 26, 28) connecting the first broad side (18) to the second wide side (20), a second narrow side being adapted from a first narrow side (22) to parallelize light incident on the second narrow side (24) and to direct it to a third narrow side (26). The illumination device is characterized in that the second narrow side (24) has a first parallelizing partial surface and a second parallel partial surface, whereby the second parallelizing partial surface is staggered relative to the first parallelizing partial surface toward the interior of the planar optical fiber region.
