Abstract
Scheinwerfer für Fahrzeuge nach dem Projektionsprinzip mit einer Lichtquelle (14), mit einem Reflektor (10), durch den von der Lichtquelle (14) ausgesandtes Licht als ein konvergierendes Lichtbündel reflektiert wird, und mit einer in Lichtaustrittsrichtung (16) nach dem Reflektor (10) angeordneten Sammellinse (18) aus Kunststoff, durch die vom Reflektor (10) reflektiertes Licht hindurchtritt und die eine in Lichtaustrittsrichtung (16) weisende konvex gekrümmte Seite (27) aufweist, wobei mit der Sammellinse (18) einstückig ein Trägerelement (30) ausgebildet ist, über das die Sammellinse (18) am Reflektor (10) gehalten ist, und das Trägerelement (30) als ein zumindest annähernd tubusförmiger Ansatz der Sammellinse (18) ausgebildet ist, dadurch gekennzeichnet, dass die Sammellinse (18) als eine Fresnellinse ausgebildet ist, dass das Trägerelement (30) über seinen Umfang Öffnungen aufweist, um eine Durchlüftung zu ermöglichen, und dass in dem Strahlengang eine Blende (20) angeordnet ist, die zur wahlweisen Erzeugung von Abblendlicht oder Fernlicht bewegbar ist.Headlamp for vehicles according to the projection principle with a light source (14), with a reflector (10), is reflected by the light emitted from the light source (14) light as a converging light beam, and with a light exit direction (16) after the reflector (10 ) arranged collecting lens (18) made of plastic, through which the reflector (10) reflected light passes and which has a in the light exit direction (16) facing convexly curved side (27), wherein integrally formed with the converging lens (18) a support member (30) is, over which the condenser lens (18) is held on the reflector (10), and the carrier element (30) as an at least approximately tubular projection of the condenser lens (18) is formed, characterized in that the condenser lens (18) formed as a Fresnel lens in that the carrier element (30) has openings around its circumference in order to allow ventilation, and in that a diaphragm (20) is provided in the beam path is arranged, which is movable to selectively produce low beam or high beam.
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Scheinwerfer für Fahrzeuge nach dem Projektionsprinzip nach der Gattung des Anspruchs 1.The invention relates to a headlight for vehicles according to the projection principle according to the preamble of claim 1.
Ein solcher Scheinwerfer ist beispielsweise aus der
Aus der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, den Scheinwerfer so auszugestalten, dass dieser verschiedene Lichtfunktionen erzeugen kann.The present invention has for its object to design the headlight so that it can produce different light functions.
Vorteile der ErfindungAdvantages of the invention
Zur Lösung dieser Aufgabe wird ein Scheinwerfer mit den Merkmalen des Anspruchs 1 vorgeschlagen. Der erfindungsgemäße Scheinwerfer hat den Vorteil, dass die Linse nur ein geringes Gewicht besitzt, wodurch das Gewicht des Scheinwerfers entsprechend reduziert werden kann. Zur wahlweisen Erzeugung von Abblendlicht und Fernlicht ist die Blende bewegbar ausgebildet.To solve this problem, a headlamp is proposed with the features of claim 1. The headlamp according to the invention has the advantage that the lens has only a low weight, whereby the weight of the headlamp can be reduced accordingly. For selective generation of low beam and high beam, the diaphragm is designed to be movable.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Scheinwerfers angegeben. Die Ausbildung gemäß Anspruch 2 ermöglicht eine weitere Gewichtsreduzierung der Sammellinse und damit des Scheinwerfers. Die Weiterbildung gemäß Anspruch 3 ermöglicht eine Verringerung des Fertigungs- und Montageaufwands des Scheinwerfers.In the dependent claims advantageous refinements and developments of the headlamp according to the invention are given. The embodiment according to claim 2 allows a further reduction in weight of the converging lens and thus of the headlamp. The development according to claim 3 allows a reduction of the manufacturing and assembly costs of the headlamp.
