Description
Die Erfindung betrifft eine Beleuchtungsvorrichtung für ein Kraftfahrzeug, welche zumindest einen Lüfter aufweist, wobei der zumindest eine Lüfter an der Beleuchtungsvorrichtung lösbar befestigbar ist.The invention relates to a lighting device for a motor vehicle, which has at least one fan, wherein the at least one fan on the lighting device is releasably attachable.
Fahrzeugscheinwerfer verfügen häufig über einen Lüfter zur Erzeugung eines Luftstroms, mit welchem beispielsweise Lichtquellen gekühlt werden. Bei LED-Scheinwerfern sind beispielsweise die LED-Lichtquellen auf einem Kühlkörper befestigt, welcher durch den Luftstrom des Kühlers gekühlt wird, und/oder die LED-Lichtquellen werden durch den Luftstrom direkt gekühlt.Vehicle headlights often have a fan for generating an air flow with which, for example, light sources are cooled. In LED headlights, for example, the LED light sources are mounted on a heat sink, which is cooled by the air flow of the radiator, and / or the LED light sources are directly cooled by the air flow.
Zur Befestigung kann der Lüfter dabei beispielsweise mit dem Scheinwerfer, d.h. mit dem Gehäuse, einem Lichtmodul oder einem Deckel für das Scheinwerfergehäuse verschraubt werden. Ein Wechsel des Lüfters ist daher nur unter Verwendung geeigneter Spezialwerkzeuge möglich.For attachment, the fan can, for example, with the headlight, i. be bolted to the housing, a light module or a cover for the headlight housing. A change of the fan is therefore possible only with the use of suitable special tools.
Es ist eine Aufgabe, eine Beleuchtungsvorrichtung für ein Kraftfahrzeug, etwa einen Fahrzeugscheinwerfer oder ein Lichtmodul für ein Kraftfahrzeug bzw. für einen Fahrzeugscheinwerfer zu schaffen, bei dem der Lüfter ohne zusätzliches Werkzeug gewechselt werden kann.It is an object to provide a lighting device for a motor vehicle, such as a vehicle headlight or a light module for a motor vehicle or for a vehicle headlight, in which the fan can be changed without additional tools.
Diese Aufgabe wird mit einer eingangs erwähnten Beleuchtungsvorrichtung dadurch gelöst, dass erfindungsgemäß eine Bajonettiereinrichtung und/oder eine Rastverbindung vorgesehen ist, mittels welcher Bajonettiereinrichtung und/oder Rastverbindung der Lüfter entweder direkt oder durch Zwischenschalten von einem oder mehreren Zwischenelementen lösbar mit der Beleuchtungsvorrichtung verbindbar ist.This object is achieved with an illumination device mentioned in the introduction, that according to the invention a bayonet device and / or a latching connection is provided, by means of which Bajonettiereinrichtung and / or latching connection of the fan either directly or by interposing one or more intermediate elements releasably connectable to the lighting device.
Durch Verbindung des Lüfters über eine Bajonetteinrichtung und/oder eine Rastverbindung, entweder direkt oder durch Zwischenschalten von einem oder mehreren Zwischenelementen, wie im Folgenden beschrieben, kann der Lüfter ohne Werkzeug gewechselt werden.By connecting the fan via a bayonet device and / or a latching connection, either directly or by interposing one or more intermediate elements, as described below, the fan can be changed without tools.
Bei einer Variante der Erfindung ist vorgesehen, dass die Beleuchtungsvorrichtung einen Lüfter-Adapter als Zwischenelement aufweist, mit welchem Lüfter-Adapter der Lüfter verbindbar ist bzw. der Lüfter in den Lüfter-Adapter einsetzbar ist, und wobei die Bajonettiereinrichtung an dem Lüfter-Adapter und einem Gegenstück der Beleuchtungseinrichtung, an welchem Gegenstück der Lüfter zu befestigen ist, angeordnet ist.In a variant of the invention, it is provided that the lighting device has a fan adapter as an intermediate element, with which fan adapter the fan can be connected or the fan can be inserted into the fan adapter, and wherein the bayonet device on the fan adapter and a counterpart of the illumination device, on which counterpart the fan is to be attached, is arranged.
Von Vorteil ist es dabei, wenn der Lüfter mit dem Lüfter-Adapter lösbar verbindbar bzw. lösbar in diesem einsetzbar ist.It is advantageous if the fan with the fan adapter detachably connectable or detachable in this is used.
Weiters kann mit Vorteil vorgesehen sein, dass der Lüfter-Adapter eine Aufnahme aufweist, in welcher Aufnahme der Lüfter befestigbar/einsetzbar, vorzugsweise lösbar befestigbar/einsetzbar ist, beispielsweise mittels einer Einrastverbindung, Einklipsverbindung oder Bajonettiereinrichtung.Furthermore, it can be advantageously provided that the fan adapter has a receptacle in which receptacle the fan can be fastened / inserted, preferably detachably fastened / inserted, for example by means of a snap connection, Einklipsverbindung or Bajonettiereinrichtung.
Bei einer anderen Variante kann vorgesehen sein, dass der Lüfter mit einer Lüfter-Abdeckung als Zwischenelement lösbar verbindbar ist, wobei die Lüfter-Abdeckung mit der Beleuchtungsvorrichtung verbindbar, beispielsweise verschraubbar ist.In another variant, it can be provided that the fan with a fan cover as an intermediate element is detachably connectable, wherein the fan cover with the lighting device connectable, for example, is screwed.
Bei einer weiteren Ausführungsform kann vorgesehen sein, dass der Lüfter mit einer Lüfter-Abdeckung als Zwischenelement lösbar verbindbar ist, wobei eine Bajonettiereinrichtung zum lösbaren Verbinden des Lüfters mit der Lüfter-Abdeckung vorgesehen ist.In a further embodiment it can be provided that the fan with a fan cover as an intermediate element is detachably connectable, wherein a Bajonettiereinrichtung is provided for releasably connecting the fan with the fan cover.
Von Vorteil ist es dabei, wenn die Lüfter-Abdeckung mit der Beleuchtungsvorrichtung, beispielsweise mit einem Kühlkörper für eine oder mehrere Lichtquellen der Beleuchtungsvorrichtung verbunden ist.It is advantageous if the fan cover is connected to the lighting device, for example with a heat sink for one or more light sources of the lighting device.
Grundsätzlich ist es von Vorteil, wenn der Lüfter-Adapter bzw. die Lüfter-Abdeckung zumindest einen Luftführ-Kanal aufweist, sodass der Luftstrom optimal gelenkt werden kann.In principle, it is advantageous if the fan adapter or the fan cover has at least one air duct, so that the air flow can be optimally steered.
Bei einer noch weiteren Variante der Erfindung ist der Lüfter mit einem Deckel - als Zwischenelement - für eine Öffnung in der Beleuchtungsvorrichtung lösbar verbindbar, wobei der Deckel mit einer Bajonettiereinrichtung bzw. mit Bajonettiermitteln versehen ist, mittels welcher er in der Öffnung lösbar verbindbar ist.In yet another variant of the invention, the fan with a cover - as an intermediate element - for an opening in the lighting device releasably connectable, wherein the lid is provided with a Bajonettiereinrichtung or with bayonet means by which it is detachably connectable in the opening.
Um den Lüfter lösbar an dem Deckel befestigen zu können, ist weiters vorgesehen, dass der Deckel eine Rastvorrichtung aufweist, mittels welcher der Lüfter lösbar an dem Deckel befestigbar ist.In order to be able to fasten the fan detachably to the cover, it is further provided that the cover has a latching device, by means of which the fan can be detachably fastened to the cover.
