Abstract
Description
Die vorliegende Endung betrifft eine Scheinwerferanordnung für ein Fahrzeug mit einer Lichtquelle, einem Reflektor, einer Projektionslinse und einer zwischen der Lichtquelle und der Projektionslinse angeordneten Blendenanordnung zum Ausblenden eines Teils des von der Lichtquelle emittierten und/oder von dem Reflektor reflektierten Lichtstrahls.The present extension concerns one Headlight arrangement for a vehicle with a light source, a reflector, a projection lens and one arranged between the light source and the projection lens Diaphragm arrangement for masking out part of the light source emitted and / or reflected by the reflector light beam.
Bei herkömmlichen Scheinwerfersystemen kann eine begrenzte Anzahl von Lichtfunktionen von den einzelnen Lichtquellen des Scheinwerfersystems erzeugt werden. Diese Lichtfunktionen umfassen im Wesentlichen ein Abblendlicht, ein Fernlicht sowie unter Umständen auch ein Nebellicht. Mit einem solchen bekannten Scheinwerfersystem lässt sich jedoch die Ausleuchtung der Umgebung nur sehr begrenzt an verschiedenartige Fahrsituationen und Wetterverhältnisse anpassen. Auf Grund der hohen Fahrzeugdichte kann das Fernlicht immer seltener benutzt werden, da durch dieses die Fahrer vorausfahrender und entgegenkommender Fahrzeuge geblendet werden. Daher wird inzwischen fast ausschließlich das Abblendlicht benutzt.With conventional headlight systems can a limited number of light functions from the individual light sources of the headlight system are generated. These include light functions essentially a low beam, a high beam and possibly also a fog light. Such a known headlight system can be used however, the illumination of the surroundings is very limited to different types Driving situations and weather conditions to adjust. Because of the high vehicle density, the high beam can are used less and less, as this means that the drivers are driving ahead and oncoming vehicles are dazzled. Therefore, meanwhile almost exclusively the low beam used.
Aus diesem Grund gibt es das Bestreben neue Scheinwerfersysteme einzuführen, mit denen Lichtfunktionen realisiert werden können, deren Lichtverteilung variabel ist und die besser an Fahr- und Umgebungsbedingungen angepasst werden können. Solche neuen intelligenten Scheinwerfersysteme werden derzeit im Rahmen des sog. AFS-Projekts (Advanced Frontlighting System) von Fahrzeugherstellern und der Zulieferindustrie entwickelt. Die Erfindung betrifft eine Scheinwerferanordnung, bei der mittels einer Blendenanordnung verschiedene Lichtgeometrien erzeugt werden können.Because of this, there is a desire to create new ones To introduce headlight systems, with which light functions can be realized, their light distribution is variable and better adapted to driving and environmental conditions can be. Such new intelligent headlight systems are currently in the As part of the AFS project (Advanced Frontlighting System) from Vehicle manufacturers and the supply industry developed. The invention relates to a headlamp arrangement in which means of a diaphragm arrangement different light geometries can be generated.

Es ist die Aufgabe der vorliegenden Erfindung, eine weitere Scheinwerferanordnung vorzuschlagen, mit der unterschiedliche Lichtverteilungsmuster erzeugt werden können.It is the task of the present Invention to propose a further headlight arrangement with which different light distribution patterns can be generated.
Diese Aufgabe wird erfindungsgemäß durch eine Scheinwerferanordnung mit den Merkmalen des Anspruchs 1 gelöst, wobei sich vorteilhafte Aus- und Weiterbildungen aus den Unteransprüchen ergeben.This object is achieved by a Headlamp assembly with the features of claim 1 solved, wherein advantageous training and further education result from the subclaims.
Die erfindungsgemäße Scheinwerferanordnung ist dadurch gekennzeichnet, dass die Blendenanordnung im Wesentlichen senkrecht zur Lichtabstrahlrichtung verschiebbar ist und dass sie verschiedene Abschnitte aufweist, die durch ein Verschieben der Blendenanordnung in den Lichtstrahl bringbar sind und in dieser Position jeweils unterschiedliche Lichtverteilungsmuster erzeugen. Vorteilhaft an der erfindungsgemäßen Scheinwerferanordnung ist, dass sie sehr einfach und daher kostengünstig realisierbar ist. Ferner können mit ihr sehr verlässlich auf mechanische Weise unterschiedliche Lichtverteilungsmustererzeugt werden.The headlight arrangement according to the invention is characterized in that the aperture arrangement essentially is displaceable perpendicular to the light emission direction and that it has different sections by moving the Aperture arrangement can be brought into the light beam and in this Position each generate different light distribution patterns. Advantageous in the headlight arrangement according to the invention is that it is very simple and therefore inexpensive to implement. Further can with her very reliable generates different light distribution patterns in a mechanical manner become.
Die verschiedenen Abschnitte unterscheiden sich vorzugsweise hinsichtlich ihrer Geometrie senkrecht zur Abstrahlrichtung. Insbesondere können die verschiedenen Abschnitte der Blendenanordnung das Lichtverteilungsmuster eines Stadtlichts, eines Abblendlichts, eines Autobahnlichts und/oder eines Fernlichts erzeugen. Diese verschiedenen Lichtfunktionen werden insbesondere im Sinne des sog. Advanced Frontlighting Systems verstanden. Die verschiedenen Abschnitte der Blendenanordnung können dabei beispielsweise überlappende Bereiche aufweisen.The different sections differ preferably with respect to their geometry perpendicular to the direction of radiation. In particular can the different sections of the diaphragm arrangement the light distribution pattern a city light, a low beam, a motorway light and / or of a high beam. These different light functions will especially understood in the sense of the so-called advanced frontlighting system. The different sections of the panel arrangement can for example overlapping Have areas.
Gemäß einer bevorzugten Ausbildung der erfindungsgemäßen Scheinwerferanordnung weist die Blendenanordnung mehrere zu einer Kette zusammengefügte Glieder auf. Zum Verschieben dieser Blendenanordnung ist vorzugsweise ein Zahnradantrieb vorgesehen, der in die Gliederkette eingreift, so dass die Blendenanordnung mittels des Zahnradantriebs verschiebbar ist. Der Zahnradantrieb kann beispielsweise Zahnräder aufweisen, welche entweder direkt in die Gliederkette eingreifen oder in eine Kette, an der die einzelnen Blendenglieder befestigt sind. Für den Zahnradantrieb ist vorzugsweise ein Schrittmotor zum Verschieben der Blendenanordnung vorgesehen.According to a preferred training the headlight arrangement according to the invention the panel arrangement has a plurality of links joined together to form a chain on. To move this diaphragm arrangement is preferably a Gear drive provided, which engages in the link chain, so that the diaphragm arrangement is displaceable by means of the gear drive is. The gear drive can have gears, for example, which either intervene directly in the link chain or in one Chain to which the individual cover links are attached. For the gear drive is preferably a stepper motor for moving the diaphragm arrangement intended.
Die Erfindung wird nun anhand eines Ausführungsbeispiels mit Bezug zu den beigefügten Figuren im Detail erläutert.The invention is now based on a embodiment with reference to the attached Figures explained in detail.
