Abstract
Description
Die vorliegende Erfindung betrifft eine Leuchte für ein Fahrzeug mit einer Lichtquelle, die zumindest eine Leuchtdiode umfasst, wobei die Leuchtdiode mit einem Vorwiderstand elektrisch verbunden ist. Des Weiteren betrifft die Erfindung einen Außenrückspiegel für ein Fahrzeug mit einer Heizeinrichtung für eine Spiegelfläche, die ein elektrisches Heizelement umfasst, und mit einer Leuchte mit einer Lichtquelle, die zumindest eine Leuchtdiode umfasst.The The present invention relates to a lamp for a vehicle with a light source comprising at least one light emitting diode, wherein the LED is electrically connected to a series resistor. Furthermore, the invention relates to an exterior rearview mirror for a vehicle with a heating device for a mirror surface comprising an electric heating element, and with a lamp with a light source, the at least one Includes light emitting diode.
Bei der Neugestaltung von Fahrzeugen ergibt sich das Problem, dass aus aerodynamischen und gestalterischen Gründen der Bauraum, welcher für die Fahrzeugleuchten zur Verfügung steht, sehr begrenzt ist. Der die Lichtquellen der Leuchten umgebende Raum ist daher häufig sehr klein. Bei der Verwendung von Leuchtdioden als Lichtquelle für die Leuchte ergibt sich in diesem Fall das Problem, dass sich die Leuchtdioden sehr stark erwärmen. Hierdurch vermindert sich die Lebensdauer der Leuchtdioden. Außerdem kann sich die Farbe des durch die Leuchtdioden ausgestrahlten Lichts soweit verändern, dass sie nicht mehr die gewünschte Lichtfunktion bereitstellen können.at the redesign of vehicles gives rise to the problem that out aerodynamic and design reasons, the installation space, which is available for the vehicle lights stands, is very limited. The surrounding the light sources of the lights Space is therefore often very small. When using Light-emitting diodes as the light source for the luminaire results in this case the problem is that the LEDs are very strong heat. This reduces the life of the LEDs. In addition, the color of the light through the LEDs radiated light so far that they do not can provide more of the desired lighting function.
Um
eine zu starke Erwärmung der Leuchtdioden bei Fahrzeugleuchten
zu vermeiden, wird in der
Des
Weiteren sind beispielsweise aus der
Es ist die Aufgabe der vorliegenden Erfindung eine Fahrzeugleuchte sowie einen Außenrückspiegel für ein Fahrzeug mit einer Leuchte bereitzustellen, bei denen auf kostengünstige Weise eine zu starke Erwärmung der Leuchtdiode vermieden wird.It the object of the present invention is a vehicle lamp as well as an exterior rearview mirror for a To provide vehicle with a light, where to cost Way to avoid excessive heating of the LED becomes.
Diese Aufgabe wird erfindungsgemäß durch eine Leuchte mit den Merkmalen des Anspruchs 1 und einem Außenrückspiegel mit den Merkmalen des Anspruchs 4 gelöst.These The object is achieved by a lamp with the features of claim 1 and an exterior rearview mirror solved with the features of claim 4.
Die erfindungsgemäße Leuchte ist dadurch gekennzeichnet, dass der Vorwiderstand mit einer Fensterfläche oder Spiegelfläche des Fahrzeugs thermisch gekoppelt ist. Der Vorwiderstand ist insbesondere in direktem Wärmekontakt mit der Fenster- oder Spiegelfläche des Fahrzeugs.The luminaire according to the invention is characterized that the series resistor with a window surface or mirror surface the vehicle is thermally coupled. The series resistor is in particular in direct thermal contact with the window or mirror surface of the vehicle.
Gemäß einer bevorzugten Ausführungsform ist der Vorwiderstand der Leuchte ein Heizelement einer Heizeinrichtung für die Fenster- oder Spiegelfläche des Fahrzeugs. Bei dem Heizelement kann es sich z. B. um einen Heizdraht oder eine Heizfläche handeln.According to one preferred embodiment is the series resistor of the lamp a heating element of a heating device for the window or mirror surface of the vehicle. In the heating element can it is z. B. to act a heating wire or a heating surface.
Bei der Verwendung eines konventionellen Vorwiderstands werden üblicherweise Kühlmittel verwendet, um der hohen Wärmeentwicklung des Vorwiderstands entgegenzuwirken. Bei der erfindungsgemäßen Leuchte ist dies nicht erforderlich, da die Kühlung des Vorwiderstands über eine Fenster- oder Spiegelfläche des Fahrzeugs erfolgt, die insbesondere mit der Außenluft in Kontakt stehen kann. Beim Betrieb der Leuchte wird somit gleichzeitig die Spiegel- bzw. Fensterfläche erwärmt, wodurch der Betauung dieser Fläche entgegengewirkt werden kann. Ist für die Fenster- oder Spiegelfläche bereits eine Heizeinrichtung vorgesehen, wird erfindungsgemäß das Heizelement dieser Heizeinrichtung als Vorwiderstand für die Leuchtdiode oder die Leuchtdioden verwendet. Es muss in diesem Fall kein separater Vorwiderstand vorgesehen werden, wodurch der Bauraumbedarf der Leuchte sowie die Herstellungskosten verringert werden.at The use of a conventional series resistor are usually Coolant used to the high heat counteract the Vorwiderstands. In the inventive This is not necessary because the cooling of the Vorwiderstands over a window or mirror surface the vehicle takes place, in particular with the outside air can be in contact. When operating the lamp is thus simultaneously the mirror or window surface is heated, causing the condensation of this surface can be counteracted. Is already for the window or mirror surface provided a heater, according to the invention, the heating element this heater as a series resistor for the light emitting diode or the light emitting diodes used. It does not have to be a separate one in this case Series resistor can be provided, whereby the space requirement of the lamp and the manufacturing costs are reduced.
Der erfindungsgemäße Außenrückspiegel ist dadurch gekennzeichnet, dass das Heizelement als Vorwiderstand mit der Leuchtdiode verbunden ist.Of the Exterior rearview mirror according to the invention is characterized in that the heating element as a series resistor connected to the light emitting diode.
Gemäß einer bevorzugten Ausführungsform des erfindungsgemäßen Außenrückspiegels ist die Leuchtdiode in einer von der Spiegelfläche und der Heizeinrichtung separaten Kammer untergebracht. Diese Kammer ist thermisch von dem als Vorwiderstand dienenden Heizelement abgekoppelt. Auf diese Weise kann vermieden werden, dass sich die Kammer, welche die Leuchtdiode umfasst, durch den Betrieb der Heizeinrichtung erwärmt.According to one preferred embodiment of the invention Outside rearview mirror is the LED in one separate from the mirror surface and the heater Chamber accommodated. This chamber is thermally of the as a series resistor disconnected heating element uncoupled. In this way can be avoided be that the chamber, which includes the light emitting diode through heats the operation of the heater.
Sowohl bei der erfindungsgemäßen Fahrzeugleuchte als auch bei dem Außenrückspiegel mit der Fahrzeugleuchte ist das Heizelement unabhängig von der Leuchte betreibbar. Es ist somit möglich, die Fenster- oder Spiegelfläche des Fahrzeugs mittels des Heizelements unabhängig von der Leuchte zu erwärmen. Andererseits erwärmt sich das Heizelement immer dann, wenn die Leuchtdiode oder die Leuchtdioden Licht emittieren und im Vorwiderstand, d. h. in dem Heizelement, elektrische Energie in thermische Energie umgewandelt wird.Either in the vehicle lamp according to the invention as also with the outside rearview mirror with the vehicle light the heating element is operable independently of the light. It is thus possible, the window or mirror surface the vehicle by means of the heating element regardless of the To heat the light. On the other hand warms up the heating element whenever the light-emitting diode or the LEDs Emit light and in the series resistor, d. H. in the heating element, electrical energy is converted into thermal energy.
Die Erfindung wird nun anhand eines Ausführungsbeispiels mit Bezug zu der Zeichnung erläutert.The Invention will now be described with reference to an embodiment Explained with reference to the drawing.
Die Figur zeigt schematisch ein Ausführungsbeispiel der erfindungsgemäßen Leuchte bzw. des erfindungsgemäßen Außenrückspiegels.The figure shows schematically a Ausfüh Example of the inventive lamp or the exterior rearview mirror according to the invention.
