Die dritte Lichtquelle ist auf der dem Reflektor abgewandten Seite der Linse vor dieser angeordnet. Dabei ist eine dritte Lichtquelle als Lichtleitring ausgeführt, der an einem radial nach innen ragenden Träger eines kreisringförmigen Reflektors befestigt ist. Der kreisförmige Reflektor reflektiert die aus der dritten Lichtquelle austretenden Lichtstrahlen in Lichtaustrittsrichtung des Scheinwerfers.The third light source is on the side facing away from the reflector of the Lens arranged in front of this. Here is a third light source as Light guide ring executed, the at a radially inwardly projecting carrier of an annular reflector is attached. The circular one Reflector reflects the emerging from the third light source Light rays in the light exit direction of the headlamp.
Als nachteilig an diesem Scheinwerfer erweist sich der komplexe Aufbau desselben. Zur Schaffung eines Positionslichtes, das den gesetzlichen Bestimmungen entspricht, sind zwei Lichtquellen sowie zwei zusätzliche Reflektoren in dem Scheinwerfer angeordnet. Außerdem sind zusätzliche Haltemittel in dem Scheinwerfer angeordnet, um diese Komponenten zu befestigen. Die Herstellung eines solchen Scheinwerfers ist aufwändig und kostenintensiv. Zudem ist der Scheinwerfer auf Grund des komplexen Aufbaus reparaturanfälliger.When disadvantageous in this headlight proves the complex structure thereof. To create a position light that complies with the legal Provisions are two light sources as well as two additional ones Reflectors arranged in the headlight. There are also additional ones Holding means arranged in the headlight to these components to fix. The production of such a headlight is complex and expensive. In addition, the headlight is due to the complex Construction susceptible to repair.
Hier setzt die vorliegende Erfindung an und macht es sich zur Aufgabe einen Scheinwerfer bereitzustellen, welcher sich durch einen einfacheren Aufbau zur Realisierung eines in den Scheinwerfer integrierten Positionslichts auszeichnet.Here employs the present invention and makes it its mission To provide a headlight, which is characterized by a simpler Construction for the realization of a position light integrated in the headlight distinguished.
VORTEILE DER ERFINDUNGADVANTAGES OF THE INVENTION
Erfindungsgemäß wird diese Aufgabe durch einen Scheinwerfer mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.According to the invention this Task by a headlight with the characterizing features of claim 1.
Gemäß Anspruch 1 ist vorgesehen, dass die zweite Lichtquelle zwischen dem Reflektor und der Linse angeordnet ist. Die Integration einer zweiten Lichtquelle in den Scheinwerfer zwischen den Reflektor und die Linse vereinfacht den Aufbau des Scheinwerfers. Dabei kann auf zusätzliche Reflektionsmittel oder Lichtleiter, wie sie im Stand der Technik vorgesehen sind, verzichtet werden. Somit ist der Scheinwerfer einfacher und kostengünstiger herstellbar. Zudem ist die Anordnung raumsparend und ermöglicht die Herstellung kleiner kompakter Scheinwerfer. Darüber hinaus erlaubt ein derart ausgeführter Scheinwerfer die Verwendung einer kombinierten ersten Lichtquelle, die als Abblendlicht und Fernlicht verwendbar ist, wodurch die Verwendung einer zusätzlichen, als Fernlicht ausgeführten Lichtquelle sowie eines zugehörigen Fernlichtreflektors verzichtet werden kann.According to claim 1 it is provided that the second light source between the reflector and the lens is arranged. The integration of a second light source in the headlight between the reflector and the lens simplified the structure of the headlamp. It can on additional reflection means or Fiber optics, as provided in the prior art omitted become. Thus, the headlight is easier and cheaper produced. In addition, the arrangement is space-saving and allows the Production of small compact headlights. In addition, such allows engineered Headlamp the use of a combined first light source, which can be used as dipped beam and main beam, reducing its use an additional, designed as a high beam Light source and an associated High beam reflector can be dispensed with.
Insbesondere kann die Beabstandung der zweiten Lichtquelle zum Reflektor größer als die Beabstandung der zweiten Lichtquelle zur Linse sein. Dadurch wird erreicht, dass der Strahlengang der von der ersten Lichtquelle ausgehenden Lichtstrahlen weitgehend von der zweite Lichtquelle unbeeinflusst ist. Vorteilhafterweise kann die zweite Lichtquelle an der dem Reflektor zugewandten Seite der Linse angrenzend angeordnet sein, wobei die Lichtaustrittsfläche der zweiten Lichtquelle der Linse zugewandt ist.Especially For example, the spacing of the second light source from the reflector may be greater than be the spacing of the second light source to the lens. Thereby is achieved that the beam path of the first light source outgoing light rays largely from the second light source is unaffected. Advantageously, the second light source arranged adjacent to the reflector facing side of the lens be, with the light exit surface the second light source facing the lens.
Vorzugsweise kann die zweite Lichtquelle im Wesentlichen oberhalb des Strahlengangs des von dem Reflektor reflektierten Lichts der ersten Lichtquelle angeordnet sein. Diese Anordnung stellt sicher, dass die Hauptfunktion des Scheinwerfers nicht dadurch eingeschränkt wird, dass der Strahlengang des vom Reflektor reflektierten Lichts durch die zweite Lichtquelle abgeschirmt wird.Preferably the second light source may be substantially above the beam path of the light reflected by the reflector of the first light source be arranged. This arrangement ensures that the main function of the headlamp is not limited by the fact that the beam path of reflected by the reflector light through the second light source is shielded.
Weiterhin kann die zweite Lichtquelle mindestens ein Leuchtmittel umfassen. Dabei kann das mindestens eine Leuchtmittel als Leuchtdiode ausgeführt sein. Die Verwendung einer Leuchtdiode als Leuchtmittel ist wartungsfreundlicher, da die Lebensdauer einer Leuchtdiode oftmals länger ist als die einer Glühlampe oder dergleichen. Zudem zeichnet sich die Leuchtdiode durch eine geringere Größe gegenüber herkömmlichen Leuchtmitteln aus, was der kompakten Bauweise des Scheinwerfers zu gute kommt.Farther the second light source may comprise at least one light source. In this case, the at least one light source can be designed as a light-emitting diode. The use of a light emitting diode as a light source is easier to maintain, because the life of a light-emitting diode is often longer than that of a light bulb or like. In addition, the LED is characterized by a lower Size compared to conventional Bulbs, what the compact design of the headlamp comes to good.
Des Weiteren kann ein Kühlkörper vorgesehen sein, der der Kühlung der zweiten Lichtquelle dient. Der Einsatz des Kühlkörpers trägt zu einer Erhöhung der Lebensdauer der zweiten Lichtquelle bei, wodurch der Wartungsaufwand weiter reduziert werden kann. Der Kühlkörper kann dabei beispielsweise ein passives Kühlelement aufweisen.Of Furthermore, a heat sink may be provided be that of cooling the second light source is used. The use of the heat sink contributes to an increase in the Lifespan of the second light source, thereby reducing the maintenance can be further reduced. The heat sink can, for example, a passive cooling element exhibit.
Vorzugsweise kann der Kühlkörper an einem Linsenträger angeordnet sein, der der Anordnung der Linse am Scheinwerfer dient. Somit kann auf zusätzliche Haltemittel in dem Scheinwerfer zur Anbringung des Kühlkörpers verzichtet werden, wodurch der Aufbau des Scheinwerfers weiter vereinfacht wird.Preferably can the heatsink on a lens wearer be arranged, which serves the arrangement of the lens on the headlight. Thus can on additional Holding means omitted in the headlight for attachment of the heat sink be, whereby the structure of the headlamp further simplified becomes.
Insbesondere kann die zweite Lichtquelle an dem Kühlkörper angeordnet sein. Auf diese Weise wird eine effiziente Kühlung der Leuchtmittel erreicht und zugleich entfällt die Verwendung und Anordnung einer zusätzlichen Halterung in dem Scheinwerfer für die zweite Lichtquelle.Especially the second light source can be arranged on the heat sink. To this Way, efficient cooling reaches the bulb and at the same time eliminates the use and arrangement of a additional Holder in the headlight for the second light source.
In einer bevorzugten Ausführungsform kann der Reflektor eine als Freiformfläche ausgeführte Reflektionsfläche aufweisen. Insbesondere kann die Reflektionsfläche im Wesentlichen elliptisch ausgeführt sein. Die elliptische Reflektionsfläche erlaubt eine kleinere und kompaktere Bauweise des Reflektors, was wiederum zu einem insgesamt kompakteren Scheinwerfer führt. Somit eignen sich derartige Reflektoren für flache Scheinwerfer mit stark geneigten Abschlussscheiben, wodurch ein mit den erfindungsgemäßen Scheinwerfern ausgeführtes Fahrzeug auf Grund der kleinen und kompakten Bauweise der Scheinwerfer besser an die aerodynamischen Anforderungen anpassbar ist, wodurch eine Verminderung des Kraftstoffverbrauchs erreicht ist.In a preferred embodiment For example, the reflector may have a reflection surface designed as a free-form surface. In particular, the reflection surface may be substantially elliptical accomplished be. The elliptical reflection surface allows a smaller and more compact design of the reflector, which in turn leads to a total more compact headlamp leads. Thus, such reflectors are suitable for flat headlights with strong inclined end lenses, creating a with the headlamps according to the invention executed Vehicle due to the small and compact design of the headlights better adaptable to the aerodynamic requirements, thereby a reduction in fuel consumption is achieved.
Vorteilhafterweise kann der Scheinwerfer modular aufgebaut sein, wodurch die Herstellung und der Zusammenbau des erfindungsgemäßen Scheinwerfers vereinfacht und kostengünstiger wird. Zu dem ermöglicht der modulare Aufbau den vereinfachten Austausch einzelner Komponenten bei einer erforderlichen Reparatur des Scheinwerfers.advantageously, the headlamp can be modular, thus reducing the production and the assembly of the headlamp according to the invention simplified and cheaper becomes. To which allows the modular design the simplified exchange of individual components with a necessary repair of the headlamp.
