(DE) BELEUCHTUNGSVORRICHTUNG FÜR EIN FAHRZEUG
(EN) LIGHTING DEVICE FOR A VEHICLE

Abstract
(DE)
Die Erfindung beschreibt eine Beleuchtungsvorrichtung für ein Fahrzeug, umfassend eine Lichtquelle (1) sowie ein linienförmiges Lichtemissionselement (2) zum Emittieren von Licht, das von der Lichtquelle (1) über eine Einkopplungsfläche (2e) des Lichtemissionselements (2) in das Lichtemissionselement (2) gespeist wird. Ferner ist ein Lichtleiterelement (3) zur Verteilung und/oder Richtung von Lichtumfasst, das von dem Lichtemissionselement (2) in das Lichtleiterelement (3) gespeist wird. Die Lichtquelle (1) ist linienförmig ausgebildet und parallel zu dem Lichtemissionselement (2) verlaufend angeordnet, so dass Licht von der Lichtquelle (1) an einer Längsseite des Lichtemissionselements (2) in die Einkopplungsfläche (2e) in das Lichtemissionselement (2) einkoppelbar ist. Das Lichtemissionselement (2) ist zumindest teilweise in einer einseitig offenen Kavität des Lichtleiterelements (3) angeordnet und kraft- und/oder formschlüssig gehalten sowie zerstörungsfrei von dem Lichtleiterelement (3) lösbar.
(EN)
The invention relates to a lighting device for a vehicle, comprising a light source (1) and a linear light emission element (2) for emitting light, which is supplied by the light source (1) via a coupling surface (2e) of the light emission element (2) in the light emission element (2). The invention also relates to a light conductor element (3) for distributing and/or directing light, which is supplied by the light emission element (2) in the light conductor element (3). The light source (1) is linear and is arranged so as to extend parallel to the light emission element (2) so that light from the light source (1) can be coupled to a longitudinal side of the light emission element (2) in an in-coupling surface (2e) in the light emission element (2). The light emission element (2) is arranged at least partially in one side of an open cavity of the light conductor element (3) and force-fittingly and/or form-fittingly held and also can be detached from the light conductor element (3) in a non-destructive manner.
(FR)
La présente invention concerne un dispositif d’éclairage pour un véhicule, comportant une source de lumière (1) ainsi qu’un élément d’émission de lumière de forme linéaire (2) servant à émettre de la lumière que la source de lumière (1) introduit dans l’élément d’émission de lumière (2) par le biais d’une surface de couplage (2e) de l’élément d’émission de lumière (2). La présente invention concerne en outre un élément guide lumière (3) pour répartir et/ou diriger de la lumière qui est introduite par l’élément d’émission de lumière (2) dans l’élément guide de lumière (3). La source de lumière (1) est conçue sous une forme linéaire et est disposée parallèle à l’élément d’émission de lumière (2) de sorte que la lumière de la source de lumière (1) peut être couplée sur un côté longitudinal de l’élément d’émission de lumière (2) dans la surface de couplage (2e) de l’élément d’émission de lumière (2). L’élément d’émission de lumière (2) est disposé au moins en partie dans une cavité ouverte d’un côté de l’élément guide de lumière (3), y est maintenu en force et/ou par conformité de forme et peut être retiré sans détériorer l’élément guide de lumière (3).
