Description
STAND DER TECHNIKSTATE OF TECHNOLOGY
Die vorliegende Erfindung betrifft einen Scheinwerfer, insbesondere einen Kraftfahrzeugscheinwerfer oder eine andere elektrische Baugruppe.The The present invention relates to a headlight, in particular a motor vehicle headlight or other electrical assembly.
Bekannte Kraftfahrzeugscheinwerfer weisen ein überwiegend abgeschlossenes Gehäuse auf, in dem zumindest ein Leuchtmittel angeordnet ist. Bei den Leuchtmitteln kann es sich bei moderneren Entwicklungen um Leuchtdioden handeln. Bei der Erzeugung von Licht, sei es durch Leuchtdioden, sei es durch herkömmliches Lampen entsteht Wärme, die, sofern die Wärme nicht abgeführt wird, zu einer Überhitzung der Leuchtmittel führt, was letztendlich eine Zerstörung des Leuchtmittels zur Folge hat. Um dies zu verhindern sind insbesondere Leuchtdioden mit Kühlkörpern versehen, welche die beim Betrieb der Leuchtdioden entstehende Wärme abführen. Damit eine ausreichende Kapazität zur Aufnahme der entstehenden Wärme zur Verfügung steht, sind diese Kühlkörper relativ großvolumig. Dieses große Volumen der Kühlkörper erschwert es, die Leuchtmittel beweglich in dem Gehäuse des Scheinwerfers anzuordnen, was allerdings für bestimmte Zwecke sinnvoll oder sogar notwendig ist.Known Motor vehicle headlights have a predominantly completed casing on, in which at least one light source is arranged. At the bulbs For example, more modern developments may be light-emitting diodes. In the production of light, be it through light diodes, be it through conventional Lamps creates heat, the, provided the heat not discharged becomes, overheating the bulb leads, which ultimately destroyed of the bulb has. To prevent this are in particular Light-emitting diodes provided with heat sinks, which dissipate the heat generated during operation of the LEDs. So one sufficient capacity to absorb the heat generated to disposal stands, these heatsinks are relative large volume. This big one Volume of the heat sink difficult it to arrange the bulbs movably in the housing of the headlamp, which, however, for certain purposes are meaningful or even necessary.
Hier setzt die vorliegende Erfindung an.Here uses the present invention.
VORTEILE DER ERFINDUNGADVANTAGES OF THE INVENTION
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Scheinwerfer beziehungsweise elektrische Baugruppe vorzuschlagen, der es ermöglicht, eine Kühlung für die Leuchtmittel oder andere Halbleiter, insbesondere Leistungshalbleiter vorzusehen, die kleinvolumig und dennoch ausreichend auch für Leuchtdioden ist.Of the present invention is based on the object, a headlight or to propose an electrical assembly which makes it possible to a cooling for the Illuminants or other semiconductors, in particular power semiconductors be provided, the small volume and yet sufficient for light-emitting diodes is.
Diese Aufgabe wird erfindungsgemäß durch einen Scheinwerfer gemäß Anspruch 1 gelöst. Weiterbildungen dieses Scheinwerfers sind in den Unteransprüchen angegeben.These The object is achieved by a Headlamp according to claim 1 solved. Further developments of this headlamp are specified in the subclaims.
Ein erfindungsgemäßer Scheinwerfer weist demnach einen Wärmetauscher auf, der beim Betrieb des Leuchtmittels die entstehende Wärme abführt. Dieser Wärmetauscher ist mit zumindest einer ersten Leitung für ein Kühlmedium verbunden. Diese erste Leitung ist von dem Wärmetauscher durch das Gehäuse nach außen geführt. Der Scheinwerfer weist eine Pumpe auf, welche das Kühlmedium durch die Leitung bewegt. Mittels des Wärmetauschers, der von dem Kühlmittel durchströmt wird, ist eine deutlich schnellere Abfuhr der in dem Leuchtmittel entstandenen Wärme möglich, als es bei den bekannten Scheinwerfern mit Kühlkörpern der Fall ist.One inventive headlight therefore has a heat exchanger on, which dissipates the heat generated during operation of the bulb. This heat exchangers is connected to at least a first conduit for a cooling medium. This first Line is from the heat exchanger through the housing outward guided. The headlight has a pump, which is the cooling medium moved through the pipe. By means of the heat exchanger, by the coolant flows through is, is a much faster removal of the light in the bulb resulting heat possible, as is the case with the known headlamps with heat sinks.
Bei einem erfindungsgemäßen Scheinwerfer kann die Pumpe außerhalb des Gehäuses angeordnet sein. Dieses ist von Vorteil, da dann der Antrieb der Pumpe, der ebenfalls eine Wärmequelle ist, nicht innerhalb des Gehäuses des Scheinwerfers, also in der Nähe der Leuchtmittel angeordnet ist.at a headlight according to the invention can the pump outside of the housing be arranged. This is advantageous because then the drive of the Pump, which is also a heat source is not inside the case the headlight, so close the light source is arranged.
Die Pumpe kann gemäß der Erfindung an einem Ende der ersten Leitung angeordnet sein. Alternativ ist es jedoch ebenso möglich, dass die Pumpe zwischen zwei Abschnitten der ersten Leitung angeordnet ist. Die erste Leitung kann eine das Kühlmedium abführende Leitung sein, es ist jedoch ebenso möglich, dass die erste Leitung eine das Kühlmedium zu dem ersten Wärmetauscher zuführende Leitung ist. Die zuführende Leitung kann zum Beispiel bei einem Kraftfahrzeug ein Ende an einer Stelle (Ausgangsstelle) außerhalb des Motorraums enden, von der dann kühle Luft angesaugt werden kann. Die Luft kann zunächst über einen Filter geführt werden. Mit einer Pumpe kann die Luft in das Gehäuse des Scheinwerfers gefördert werden. Zwischen Scheinwerfergehäuse und Pumpe kann ein Kompressionskühler angeordnet sein, um die Luft, die in der Pumpe möglicherweise zugeführte Kompressionswärme zu entziehen.The Pump can according to the invention be arranged at one end of the first line. Alternatively it is however, it is equally possible that the pump is arranged between two sections of the first line is. The first conduit may be a conduit discharging the cooling medium but it is equally possible that the first conduit is a cooling medium to the first heat exchanger feeding Line is. The feeding For example, in a motor vehicle, line may terminate at one end Place (exit point) outside end of the engine compartment, from which then cool air can be sucked. The air can first over a Filter led become. With a pump, the air can be conveyed into the housing of the headlamp. Between headlight housing and pump can be a compression cooler be arranged to extract the air, the heat of compression possibly supplied in the pump.
Die Ansaugstelle kann zum Beispiel im hinteren Teil des Fahrzeugs zum Beispiel im Kofferrau, im Radkasten, ... angeordnet sein.The For example, the intake point can be in the rear of the vehicle for Example in the box woman, in the wheel arch, ... be arranged.
Ein vorteilhafter erfindungsgemäßer Scheinwerfer kann zumindest eine zweite Leitung umfassen, die ebenfalls für das Kühlmedium vorgesehen ist. Diese zweite Leitung kann ebenso wie die erste Leitung mit dem Wärmetauscher verbunden sein.One advantageous inventive headlight may comprise at least a second conduit, which also for the cooling medium is provided. This second line can as well as the first line with the heat exchanger be connected.
Die zumindest eine erste Leitung kann dann die zuführende Leitung für das Kühlmedium sein, wenn die zumindest eine zweite Leitung die abführende Leitung für das Kühlmedium ist. Die zweite Leitung kann ebenso wie die erste Leitung durch das Gehäuse des Scheinwerfers nach außen geführt sein. Alternativ ist es möglich, dass die zweite Leitung eine zuführende Leitung ist, wenn die erste Leitung eine das Kühlmedium vom ersten Wärmetauscher abführende Leitung ist.The at least one first line can then supply the feeding line for the cooling medium be if the at least one second line the laxative line for the cooling medium is. The second line can as well as the first line through the housing of the headlight to the outside be guided. Alternatively it is possible that the second line is an afferent Line is when the first line a the cooling medium from the first heat exchanger laxative Line is.
Ein erfindungsgemäßer Scheinwerfer kann neben dem ersten Wärmetauscher einen weiteren, d. h. zweiten Wärmetauscher aufweisen, der vorteilhaft außerhalb des Gehäuses des Scheinwerfers angeordnet ist. Dieser zweite Wärmetauscher kann sowohl mit der ersten Leitung und mit der zweiten Leitung verbunden sein, um einen geschlossenen Kreislauf für das Kühlmedium zwischen den beiden Wärmetauschern zu schaffen. Mit diesem zweiten Wärmetauscher kann man dann die aus dem Gehäuse über das Kühlmedium abgeführte Wärme dem Kühlmedium entziehen und diese entzogene Wärme an die Umgebung abführen. Das Kühlmedium kann dann mit geringerer Temperatur zurück in das Gehäuse und zum ersten Wärmetauscher gefördert werden, um weitere Wärme aufzunehmen.A headlight according to the invention may have, in addition to the first heat exchanger, a further, ie second heat exchanger, which is advantageously arranged outside the housing of the headlight. This second heat exchanger may be connected to both the first conduit and the second conduit to provide a closed circuit for the cooling medium between the two heat exchangers. With this second heat exchanger can then withdraw the heat dissipated from the housing via the cooling medium to the cooling medium and this heat withdrawn dissipate the environment. The cooling medium can then be conveyed back into the housing and to the first heat exchanger at a lower temperature in order to absorb further heat.
Die Pumpe eines erfindungsgemäßen Scheinwerfers kann am Ende der zweiten Leitung oder zwischen zwei Abschnitten der zweiten Leitung angeordnet sein.The Pump of a headlamp according to the invention can be at the end of the second pipe or between two sections be arranged the second line.
Bei dem Kühlmedium kann es sich im übrigen um ein Gas, insbesondere um Luft, oder um eine Flüssigkeit, insbesondere um Wasser, handeln.at the cooling medium It may be otherwise a gas, in particular air, or a liquid, especially water, act.
