Die Kontakte werden hierbei durch die Kunststoffvergussmasse von der Leuchtdiode nach außen geführt. Eine Kontaktierung mit den weiteren stromführenden Kabeln ist hierbei so ausgestaltet, dass sie in einem Trockenbereich erfolgen kann. Eine derartige Leuchte ist an sich gut gegen Feuchtigkeit geschützt, sie weist jedoch den Nachteil auf, dass die gesamte Leuchte mit dem integralen Gehäuse in der Nähe des zu beleuchtenden Objektes installiert sein muss. In vielen Fällen ist jedoch in den Bereichen des Kraftwagens, in denen die Leuchten angebracht werden, der Bauraum sehr begrenzt, weshalb es bisweilen problematisch ist, eine geeignete Position für die Leuchte bereitzustellen, die gleichzeitig eine gute Ausleuchtung des zu beleuchtenden Gegenstandes gewährleistet.The Contacts are characterized by the plastic grout of the LED to the outside guided. A contact with the other current-carrying cables is here designed so that it can be done in a dry area. A Such light is well protected against moisture, they However, has the disadvantage that the entire lamp with the integral housing near of the object to be illuminated must be installed. In many cases However, in the areas of the motor vehicle in which the lights are mounted space is very limited, which is why it sometimes problematic is a suitable position for to provide the luminaire while providing good illumination ensures the object to be illuminated.
Die Aufgabe der Erfindung besteht darin, eine, an einen Außenbereich eines Kraftwagens angebrachte Leuchte bereitzustellen, die im Gegensatz zum Stand der Technik platzsparend angeordnet ist und dabei eine gute Ausleuchtung gewährleistet.The The object of the invention is a, to an outdoor area to provide a motor vehicle mounted lamp, in contrast to the State of the art is arranged to save space while doing a good Illumination guaranteed.
Die Lösung der Aufgabe besteht in einer Leuchte mit den Merkmalen des Patentanspruchs 1.The solution the task consists in a lamp with the features of the claim 1.
Die Leuchte nach Patentanspruch 1 ist an einem Außenbereich eines Kraftwagens angeordnet. Unter Außenbereich wird hierbei verstanden, dass die Lichtstrahlen, die durch die Leuchte erzeugt werden, in ihrer Wirkrichtung außerhalb des Fahrzeuges liegen. Die Leuchte weist mindestens eine Leuchtdiode als Leuchtmittel auf, wobei die Leuchtdiode in eine Kunststoffvergussmasse eingegossen ist. Unter Leuchtdiode wird hierbei das elektromagnetische Wellen erzeugende Bauelement verstanden, das in der Regel in Form eines Halbleitermaterials auf einem Halbleitersubstrat ausgestaltet ist und ggf. noch Kontaktierungen umfasst.The Luminaire according to claim 1 is on an exterior of a motor vehicle arranged. Under outdoor area is here understood that the light rays passing through the light are generated, lie in their effective direction outside of the vehicle. The luminaire has at least one light-emitting diode as lighting means, wherein the light-emitting diode is cast in a plastic casting compound is. Under LED here is the electromagnetic waves generating component, which is usually in the form of a Semiconductor material is designed on a semiconductor substrate and possibly still contacts.
Ebenfalls in die Kunststoffvergussmasse ist ein Lichtleiter eingegossen. Dieser Lichtleiter nimmt die von der Leuchtdiode emittierten Lichtwellen auf und führt sie aus der Kunststoffvergussmasse heraus. Außerhalb dieses Kunststoffgehäuses, das durch die Kunststoffvergussmasse gebildet wird, weist der Lichtleiter Lichtaustrittsöffnungen auf, die zur Beleuchtung von Bereichen des Kraftwagens oder eines Kraftwagenumfeldes vorgesehen sind.Also in the plastic grout a light guide is poured. This Light guide takes the light waves emitted by the light emitting diode up and leads they out of the Kunststoffvergussmasse. Outside of this plastic housing, that through the plastic grout is formed, the optical fiber has Light exits On, for the illumination of areas of the motor vehicle or a Automotive environment are provided.
Eine derartige Leuchte weist den Vorteil auf, dass sie neben der Dichtheit gegenüber Wasser und Schmutz einen Lichtleiter aufweist, der das Licht an zu beleuchtende Stellen führt, wobei das Leuchtmittel an sich, in Form der Leuchtdiode und des Kunststoffgehäuses abseits des zu beleuchtenden Bereiches angeordnet sein kann. Hierbei kann in einem dichtgepackten Umfeld Bauraum eingespart werden, indem die Leuchte an sich verlegt werden kann.A Such lamp has the advantage that it in addition to the tightness across from Water and dirt has a light guide to the light to leads lighting spots, the lighting means itself, in the form of the light emitting diode and the Plastic housing can be arranged away from the area to be illuminated. in this connection can be saved in a tightly packed environment space by the lamp can be installed on itself.
Der Lichtleiter besteht in einer Ausgestaltungsform der Erfindung aus Kunststoff. Dies ist ein kostengünstiges Material, das gut formbar ist und leicht bearbeitbar ist.Of the Optical fiber is in an embodiment of the invention Plastic. This is a low cost Material that is easy to shape and easy to machine.
Der Lichtleiter ist wiederum in einer Ausgestaltungsform der Erfindung an seinen Austrittsöffnungen, die auch als Lichtaustrittsoptik bezeichnet werden kann, mit polierten Oberflächen versehen. Insbesondere bei Verwendung eines Kunststofflichtleiters, der an seinen übrigen Oberflächen matt ist, so dass an diesen kein Licht austreten kann, können so definierte Lichtaustrittsöffnungen geschaffen werden, die eine Konzentration des Lichtbündels ermöglichen.Of the Optical fiber is in turn in an embodiment of the invention at its outlet openings, which can also be referred to as light exit optics, with polished surfaces Mistake. Especially when using a plastic optical fiber, the one at his other surfaces is dull, so that no light can escape from them, can thus be defined Light exits be created, which allow a concentration of the light beam.
Derartige Lichtaustrittsöffnungen können auf der Stirnseite oder auch entlang eines längeren Lichtleiters verlaufen. Hierbei ist es möglich, längere Bereiche gleichmäßig zu beleuchten.such Light exits can on the front side or along a longer light guide. Here it is possible longer To illuminate areas evenly.
Die erfindungsgemäße Leuchte kann an vielen verschiedenen Bereichen des Kraftwagens angeordnet sein. Zweckmäßige Bereiche sind beispielsweise eine Bodenleuchte in einer Kraftwagentür, die bei Dunkelheit dem Fahrgast beim Aussteigen aus dem Fahr zeug oder beim Einsteigen in das Fahrzeug den Boden beleuchtet und so bspw. vor Pfützen warnt. Eine derartige Leuchte ist bei einer herkömmlichen Bauweise stets einer starken Verschmutzung im Türunterbereich ausgesetzt. Durch die erfindungsgemäße Leuchte kann diese Verschmutzung unterbunden werden.The Lamp according to the invention can be arranged on many different areas of the motor vehicle be. Appropriate areas For example, a floor lamp in a motor vehicle door, the at Darkness to the passenger when getting out of the vehicle or when Getting into the vehicle lights the ground and so, for example, before Puddles warns. Such a lamp is always one in a conventional construction heavy pollution in the door area exposed. By the lamp according to the invention, this pollution can be prevented become.
Eine weitere zweckmäßige Anwendung der Leuchte ist eine dritte Bremsleuchte. Eine dritte Bremsleuchte ist häufig in einem Heckdeckel eines Fahrzeugs angeordnet, wo ebenfalls diese Leuchte einer starken Verschmutzung bzw. Feuchtigkeit ausgesetzt ist und gleichzeitig häufig ein Mangel an Bauraum vorherrscht. Auch hier können die Vorzüge der erfindungsgemäßen Leuchte gut ausgenutzt werden.Another useful application of the lamp is a third brake light. A third Brake light is often located in a trunk lid of a vehicle, where also this lamp is exposed to heavy pollution or moisture and at the same time there is often a lack of space. Again, the merits of the lamp according to the invention can be well utilized.
Eine weitere zweckmäßige Ausgestaltungsform der Leuchte besteht in der Anwendung als eine Kennzeichenleuchte. Kennzeichenleuchten sind ebenfalls stets einer hohen Verschmutzung und einer hohen Feuchtigkeitsbelastung ausgesetzt. Sie sind in der Regel in einer Kennzeichenmulde angeordnet und müssen sich dort den Bauraum beispielsweise mit einer Türgriffanordnung und(oder einer dritten Bremsleuchte teilen. Hierbei kann es zweckmäßig sein, die erfindungsgemäße Leuchte seitlich in der Kennzeichenmulde anzuordnen und den Lichtleiter entlang des Kennzeichens so zu verlegen, dass das Kennzeichen gleichmäßig beleuchtet wird.A further expedient embodiment The luminaire consists in the application as a license plate lamp. License plate lights are also always a high pollution and exposed to a high moisture load. they are in the Usually arranged in a license plate well and have there the space for example, with a door handle assembly and (or a third brake light, it may be convenient to the lamp according to the invention to be arranged laterally in the license plate recess and along the light guide of the license plate so that the license plate illuminates evenly becomes.
In einer zweckmäßigen Ausgestaltungsform der Erfindung ein Leuchtmittel mehrere Lichtleiter speisen. Hierbei können die zwei oder mehreren Lichtleiten direkt vor dem Eintritt der Lichtwellen an der LED verzweigen. Andererseits ist es möglich, dass der Lichtleiter Außerhalb der Kunststoffvergussmasse verzweigt und so mehrere Lichtleiter bildet. Auf diese Weise können durch starke Leuchtmittel mehrere verschieden Objekte beleuchtet werden.In an expedient embodiment of the Invention a light source feed several optical fibers. in this connection can the two or more light-guiding just before the entrance of the light waves branch off at the LED. On the other hand, it is possible that the light guide Outside the Kunststoffvergussmasse branches and so several optical fibers forms. That way you can Illuminated by strong bulbs several different objects become.
Weiterhin kann es zweckmäßig sein, zur Verstärkung des Beleuchtungseffektes einen Lichtleiter durch zwei oder mehrere Leuchtmittel gespeist werden. Dies ist besonders dann vorteilhaft, wenn weitere Strecken durch den Lichtleiter zurückgelegt werden und dabei die Lichtstärke abnimmt. Hierbei kann der Lichtleite an mehreren (gegebenenfalls auch durch Verzweigungen) in die Kunststoffvergussmasse mehrer Leuchten eingegossen (bzw. integriert sein).Farther it may be appropriate for reinforcement the lighting effect, a light guide by two or more Illuminants are fed. This is especially beneficial if further distances are covered by the light guide and thereby the luminous intensity decreases. Here, the light guide at several (possibly also by branching) in the Kunststoffvergussmasse several lights poured (or integrated).
