Abstract
Fahrzeugscheinwerfer mit einem Reflektor (10), in den wenigstens eine Lichtquelle (12) für eine Lichtfunktion eingesetzt ist und durch den von der Lichtquelle (12) ausgesandtes Licht zur Erzeugung einer Beleuchtungsstärkeverteilung für die Lichtfunktion reflektiert wird, wobei in den Reflektor (10) wenigstens eine weitere Lichtquelle (22) für die Funktion eines Begrenzungslichts eingesetzt ist und durch den Reflektor (10) von der Begrenzungslichtquelle (22) ausgesandtes Licht zur Erzeugung einer Beleuchtungsstärkeverteilung für das Begrenzungslicht reflektiert wird, wobei der wenigstens einen Begrenzungslichtquelle (22) wenigstens eine Abschirmvorrichtung (50; 60; 70) zugeordnet ist, durch die von der Begrenzungslichtquelle (22) ausgesandtes, auf wenigstens einen Teilbereich (18) des Reflektors (10) treffendes Licht zumindest abgeschwächt wird, und wobei durch den Teilbereich (18) ohne die Abschirmvorrichtung (50; 60; 70) ausgesandtes und auf diesen treffendes Licht derart reflektiert würde, dass für das Begrenzungslicht zu hohe Beleuchtungsstärken erzeugt würden, dadurch gekennzeichnet, dass die Abschirmvorrichtung (70) zumindest teilweise lichtdurchlässig ausgebildet ist und dass die Abschirmvorrichtung...vehicle headlights with a reflector (10) into which at least one light source (12) for a light function is inserted and by the light emitted from the light source (12) Light for generating an illuminance distribution for the light function is reflected, wherein in the reflector (10) at least one further light source (22) for the function of a limiting light is used and by the Reflector (10) emitted by the limiting light source (22) Reflected light for generating an illuminance distribution for the limiting light is, wherein the at least one limiting light source (22) at least a shielding device (50; 60; 70) is associated, through which from the limiting light source (22) emitted on at least a partial area (18) of the reflector (10) incident light at least attenuated is, and by the portion (18) without the shielding device (50; 60; 70) emitted and striking light in such a way would reflect that for the limiting light would be generated too high illuminance, thereby characterized in that the shielding device (70) at least partially translucent is formed and that the shielding device ...

Erfindung geht aus von einem Fahrzeugsheinwerfer nach der Gattung
des Anspruchs 1. Ein derartiger Scheinwerfer ist aus der

Vorteile der ErfindungAdvantages of the invention
Der erfindungsgemäße Scheinwerfer mit den Merkmalen gemäss Anspruch 1 hat demgegenüber den Vorteil, dass durch die Abschirmvorrichtung die Beleuchtungsstärkewerte für das Begrenzungslicht auf die zulässige Höhe begrenzt werden können, so dass auch Begrenzungslichtquellen mit großem Lichtstrom verwendet werden können. Zudem wird durch die lichtdurchlässige Ausgestaltung der Abschirmvorrichtung eine größtmögliche Nutzung des von der Begrenzungslichtquelle ausgesandten Lichts ermöglicht.Of the inventive headlight with the features according to Claim 1 has the opposite Advantage that by the shielding the illuminance values for the limiting light on the permissible Height limited can be so that limiting light sources with a large luminous flux can be used can. In addition, through the translucent Design of the shielding a maximum use of the of the Limiting light source emitted light allows.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Scheinwerfers angegeben. Durch die Ausbildung gemäss Anspruch 2 wird erreicht, dass die eigentliche Lichtfunktion des Scheinwerfers durch die Abschirmvorrichtung geringstmöglich beeinflusst wird. Die Ausbildung der Abschirmvorrichtung gemäss Anspruch 4 wird eine größtmögliche Nutzung des von der Begrenzungslichtquelle ausgesandten Lichts ermöglicht.In the dependent claims are advantageous embodiments and refinements of the headlight according to the invention specified. The training according to claim 2 ensures that the actual light function of the headlamp through the shielding device little as possible being affected. The embodiment of the shielding device according to claim 4 will be the greatest possible use allows the emitted light from the limiting light source.
