Abstract

Die Erfindung betrifft einen Scheinwerfer (1) für Fahrzeuge mit einem Reflektor (3), einer Linse (4) und einer zwischen dem Reflektor (3) und der Linse (4) angeordneten Blendenwelle (11), welche um eine horizontale und quer zur optischen Achse (200) verlaufende Drehachse (100) in zwei oder mehr Drehstellungen verstellbar ist, und wobei die Mantelfläche (12) der Blendenwelle (11) für jede Drehstellung zumindest jeweils eine Brennlinie (20, 21) aufweist, welche eine Hell-Dunkel-Grenze (1001, 2001) einer Lichtverteilung (1000, 2000) erzeugt, wobei die Linse (4) um eine vertikale Achse (300), welche vorzugsweise durch den Brennpunkt der Linse (4) bzw. einen Brennpunkt des Reflektors (3) verläuft, zur Erzeugung eines dynamischen Kurvenlichtes verschwenkbar ist. Erfindungsgemäß weist die Blendenwelle (11) in Umfangsrichtung, d.h. in Drehrichtung gesehen, in einem definierten Drehwinkel-Bereich (δ), eine Mantelfläche (12) mit einer Ausgestaltung zur Bildung eines Brennlinienbereiches für zwei oder mehrere Brennlinien (20, 20', 21) für abgeblendetes Licht auf, wobei eine Brennlinie für abgeblendetes Licht zumindest einen ersten Brennlinien-Abschnitt (20a, 20a', 21a) zur Erzeugung einer Hell-Dunkelgrenze eines Lichtbildes auf der Gegenverkehrsseite und zumindest einen zweiten Brennlinien-Abschnitt (20b, 20b', 21b) zur Erzeugung einer Hell-Dunkelgrenze eines Lichtbildes auf der Fahrzeugseite aufweist, und wobei die Blendenwelle (11) zumindest in einem Bereich des zumindest einen ersten Brennlinienabschnittes (20a') einer Brennlinie (20') für abgeblendetes Licht zumindest eine Erhebung (80) gegenüber ersten Brennlinienabschnitten (20a, 21a) von benachbarten Brennlinien (20, 21) für abgeblendetes Licht aufweist.

The invention relates to a headlamp (1) for vehicles with a reflector (3), a lens (4) and between the reflector (3) and the lens (4) arranged aperture shaft (11) which is about a horizontal and transverse to the optical Axis (200) extending axis of rotation (100) in two or more rotational positions is adjustable, and wherein the lateral surface (12) of the diaphragm shaft (11) for each rotational position at least one focal line (20, 21) which has a cut-off (1001, 2001) of a light distribution (1000, 2000), wherein the lens (4) about a vertical axis (300), which preferably through the focal point of the lens (4) and a focal point of the reflector (3) runs to Generation of a dynamic cornering light is pivotable. According to the invention, the diaphragm shaft (11) has a circumferential surface (12) with a configuration for forming a focal line region for two or more focal lines (20, 20 ', 21) in the circumferential direction, ie in the direction of rotation, in a defined rotational angle range (δ). for dimmed light, wherein a dimmed light focal line includes at least a first focal line portion (20a, 20a ', 21a) for generating a light-dark boundary of a counterpart light image and at least a second focal line portion (20b, 20b', 21b ) for generating a light-dark boundary of a light image on the vehicle side, and wherein the diaphragm shaft (11) at least in a region of the at least one first focal line section (20a ') of a focal line (20') for dimmed light at least one elevation (80) opposite first focal line sections (20a, 21a) of adjacent focal lines (20, 21) for dimmed light.
