Abstract
Description
Die Erfindung betrifft einen Scheinwerfer für Fahrzeuge mit einer Lichtquelle, mit einer Linseneinrichtung enthaltend eine Mehrzahl von Linsen, wobei mindestens eine Linse in Richtung einer optischen Achse verschiebbar angeordnet ist, und mit einer Blende, die zwischen der Lichtquelle und der Linseneinrichtung angeordnet ist.The The invention relates to a headlamp for vehicles with a light source, with a lens device containing a plurality of lenses, wherein at least one lens displaceable in the direction of an optical axis is arranged, and with a diaphragm, which is between the light source and the lens device is arranged.

der
Aufgabe der vorliegenden Erfindung ist es, einen Scheinwerfer für Fahrzeuge derart weiterzubilden, dass mit geringem Aufwand eine Anpassung der Lichtverteilung an unterschiedliche Verkehrssituationen des Fahrzeugs erfolgen kann.task The present invention is a headlamp for vehicles in such a way that with little effort an adjustment the light distribution to different traffic situations of the vehicle can be done.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass die Linseneinrichtung derart verstellbar angeordnet ist, dass die Leuchtbreite in Abhängigkeit von verkehrssituationsabhängigen Bedingungen verändert wird.to solution This object is the invention in conjunction with the preamble of the patent claim 1, characterized in that the lens device is arranged so adjustable that the luminous width in dependence of traffic situation dependent Conditions changed becomes.
Vorteilhaft ermöglicht die Erfindung eine kontinuierliche Anpassung der Scheinwerfer-lichtverteilung an die Verkehrssituation, wobei durch Verstellung mindestens einer Linse der Linseneinrichtung eine Leuchtbreite bzw. Streubreite des Scheinwerfers variiert wird. Vorteilhaft wird mittels Bewegung mindestens einer Linse ein Aufweiten bzw. Zusammenziehen der Lichtverteilung unter Beibehaltung des Kollimationsgrades ermöglicht.Advantageous allows the invention a continuous adjustment of the headlight light distribution the traffic situation, wherein by adjusting at least one lens the lens device a luminous width or spread of the headlamp is varied. Advantageously, by means of movement at least one Lens expansion or contraction of the light distribution under Maintaining the degree of collimation allows.
Nach einer Weiterbildung der Erfindung erfolgt mittels einer minimalen Anzahl von Linsen bzw. einer minimalen Anzahl von beweglichen Linsen eine Variation der Leuchtbreite, wobei der Verlauf einer Hell-Dunkel-Grenze in einem mittleren Abschnitt der jeweils gebildeten Lichtverteilung unverändert bleibt. Die Vertikalwinkellage der Hell-Dunkel-Grenze bleibt somit unverändert.To a development of the invention by means of a minimum Number of lenses or a minimum number of movable lenses a variation of the luminous width, whereby the course of a light-dark border in a central portion of each formed light distribution unchanged remains. The vertical angle position of the cut-off line thus remains unchanged.
Nach einer Weiterbildung der Erfindung erfolgt die Veränderung der Leuchtbreite durch axiales Verschieben mindestens einer lichtquellennahen Linse. Das Verschieben der lichtquellennahen Linse kann beispielsweise in Abhängigkeit von der Fahrgeschwindigkeit erfolgen, so dass bei einer relativ hohen Geschwindigkeit des Fahrzeugs die Leuchtbreite relativ klein und bei einer relativ kleinen Geschwindigkeit des Fahrzeugs die Leuchtbreite relativ groß ist.To a development of the invention, the change takes place the luminous width by axial displacement of at least one light source near Lens. Moving the light source near the lens, for example dependent on from the driving speed, so that at a relative high speed of the vehicle, the luminous width is relatively small and at a relatively low speed of the vehicle the Luminous width is relatively large.
Nach einer Weiterbildung der Erfindung kann die Blende auch einstückig mit der als LED-Leuchtelement (LED-Chip) ausgebildeten Lichtquelle verbunden sein, so dass der Scheinwerfer relativ kompakt ausgebildet ist.To a development of the invention, the aperture also integrally with connected as a LED lighting element (LED chip) formed light source be, so that the headlamp is relatively compact.
Nach einer Weiterbildung der Erfindung kann der Lichtquelle ein Reflektor zugeordnet sein, so dass der Scheinwerfer nach dem Projektionsprinzip eine vorgegebene Lichtverteilung, vorzugsweise eine Abblendlichtverteilung bzw. Autobahnlichtverteilung erzeugt.To a development of the invention, the light source is a reflector be assigned so that the headlight according to the projection principle a predetermined light distribution, preferably a low beam distribution or motorway light distribution generated.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further Advantages of the invention will become apparent from the other dependent claims.
