Description
Die Erfindung betrifft eine Beleuchtungsvorrichtung für ein Fahrzeug gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a lighting device for a vehicle according to the preamble of claim 1.
Beleuchtungsvorrichtungen für Fahrzeuge sind aus dem Stand der Technik bekannt. Beispielsweise ist in
Der Erfindung liegt die Aufgabe zu Grunde, eine gegenüber dem Stand der Technik verbesserte Beleuchtungsvorrichtung für ein Fahrzeug anzugeben.The invention is based on the object of specifying an improved over the prior art lighting device for a vehicle.
Die Aufgabe wird erfindungsgemäß mit den in Anspruch 1 angegebenen Merkmalen gelöst.The object is achieved with the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine Beleuchtungsvorrichtung für ein Fahrzeug umfasst ein Gehäuse, welches einen Innenraum zumindest abschnittsweise von einer äußeren Umgebung begrenzt, zumindest ein im Innenraum angeordnetes Leuchtelement zur Emittierung von Licht, mindestens ein im Innenraum angeordnetes Trocknungselement zur Absorption von Feuchtigkeit im Innenraum und mindestens ein Druckausgleichselement zum Druckausgleich zwischen dem Innenraum und der äußeren Umgebung.A lighting device for a vehicle comprises a housing which delimits an interior space, at least in sections, from an external environment, at least one light-emitting element arranged in the interior, at least one drying element arranged in the interior for absorbing moisture in the interior and at least one pressure-equalizing element for equalizing pressure the interior and the external environment.
Erfindungsgemäß ist vorgesehen, dass das zumindest eine Leuchtelement als eine organische Leuchtdiode ausgebildet ist.According to the invention, it is provided that the at least one luminous element is designed as an organic light-emitting diode.
Gegenüber herkömmlichen Leuchtdioden ergibt sich beim Einsatz organischer Leuchtdioden (kurz: OLEDs) der Vorteil, dass diese Flächenemitter sind und eine homogene Leuchtfläche ermöglichen. Da OLEDs diffuses Licht emittieren, ist ein nahezu blendfreies Licht emittierbar. Zudem können OLEDs auf biegsamen Substraten hergestellt werden, so dass eine variable Formgebung der Lichtquelle möglich ist.Compared to conventional light-emitting diodes, the use of organic light-emitting diodes (OLEDs for short) results in the advantage that they are surface emitters and enable a homogeneous light-emitting surface. Since OLEDs emit diffused light, an almost glare-free light is emitted. In addition, OLEDs can be produced on flexible substrates, so that a variable shape of the light source is possible.
Mittels des im Innenraum angeordneten Trocknungselements kann eine Wasserempfindlichkeit der OLEDs kompensiert werden, so dass eine in das Gehäuse diffundierende Feuchtigkeit absorbiert wird. Druckunterschiede zwischen dem Innenraum und der äußeren Umgebung können mittels des Druckausgleichelements ausgeglichen werden.By means of the drying element arranged in the interior, a water sensitivity of the OLEDs can be compensated, so that a moisture diffusing into the housing is absorbed. Pressure differences between the interior and the external environment can be compensated by means of the pressure compensation element.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand von Zeichnungen näher erläutert.Embodiments of the invention are explained in more detail below with reference to drawings.
