Abstract
Description
Die Erfindung betrifft eine Beleuchtungsvorrichtung für ein Fahrzeug mit zumindest einem Leuchtmittel.The invention relates to a lighting device for a vehicle with at least one light source.
Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung einer Beleuchtungsvorrichtung für ein Fahrzeug.The invention further relates to a method for producing a lighting device for a vehicle.
Aus der
Der Erfindung liegt die Aufgabe zu Grunde, eine gegenüber dem Stand der Technik verbesserte Beleuchtungsvorrichtung für ein Fahrzeug sowie ein Verfahren zur Herstellung einer Beleuchtungsvorrichtung für ein Fahrzeug anzugeben.The invention is based on the object to provide a comparison with the prior art improved lighting device for a vehicle and a method for producing a lighting device for a vehicle.
Hinsichtlich der Beleuchtungsvorrichtung wird die Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale und hinsichtlich des Verfahrens durch die im Anspruch 7 angegebenen Merkmale gelöst.With regard to the lighting device, the object is achieved by the features specified in claim 1 and in terms of the method by the features specified in claim 7.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die Beleuchtungsvorrichtung für ein Fahrzeug mit zumindest einem Leuchtmittel zeichnet sich erfindungsgemäß durch eine mechanische flexible und elektrisch mit dem zumindest einen Leuchtmittel gekoppelte Leiterbahnfolie und einen Kühlkörper aus, wobei die Leiterbahnfolie zumindest abschnittsweise flächig mit dem Kühlkörper verbunden ist und im Bereich des Leuchtmittels eine Aussparung aufweist. Das Leuchtmittel ist durch die Aussparung hindurch mit dem Kühlkörper verbunden.The lighting device for a vehicle with at least one light-emitting means is characterized by a mechanical flexible and electrically coupled to the at least one conductor strip and a heat sink, wherein the conductor foil is connected at least partially flat with the heat sink and in the region of the light-emitting means has a recess. The light source is connected through the recess with the heat sink.
Die erfindungsgemäße Beleuchtungsvorrichtung ermöglicht aufgrund der Aussparung und der Verbindung des Leuchtmittels mit dem Kühlkörper durch die Aussparung, dass zwischen dem Leuchtmittel und dem Kühlkörper keine wärmeisolierende Schicht angeordnet ist. Somit wird in besonders vorteilhafter Weise ein signifikant verbesserter Wärmeübergang zwischen dem Leuchtmittel und dem Kühlkörper erreicht. Deshalb kann eine Kühlleistung und daraus folgend eine Größe des Kühlkörpers bei gleichbleibender elektrischer Leistung des Leuchtmittels verringert werden oder das Leuchtmittel kann bei gleichbleibender Kühlleistung mit einer höheren elektrischen Leistung betrieben werden.The lighting device according to the invention allows due to the recess and the connection of the lamp with the heat sink through the recess that between the lamp and the heat sink, no heat-insulating layer is arranged. Thus, a significantly improved heat transfer between the lamp and the heat sink is achieved in a particularly advantageous manner. Therefore, a cooling capacity and consequent size of the heat sink can be reduced while maintaining the electric power of the light source, or the light source can be operated at a constant electric power with the same cooling performance.
