Abstract

Scheinwerfer für Fahrzeuge (1) mit einem zwei Brennorte aufweisenden schalenförmigen Reflektor (2) und mit einer zwischen einer Linse (3) und dem Reflektor (2) angeordneten Blendenwelle (4), die um eine horizontale und quer zur optischen Achse verlaufende Drehachse in mehrere Drehstellungen verstellbar angeordnet ist, wobei die Mantelfläche (6) der Blendenwelle (4) für jede Drehstellung eine Brennlinie aufweist, welche eine Hell-Dunkel-Grenze einer Lichtfigur erzeugt, wobei die Blendenwelle (4) als ein langgestreckter Hohlkörper ausgebildet ist, wobei die Kontur des Hohlkörpers bzw. der Brennlinie durch Erzeugen eines inneren Hochdrucks hergestellt ist.

Figure 00000001
Headlamp for vehicles (1) with a bowl-shaped reflector (2) having two focal points and with a diaphragm shaft (4) arranged between a lens (3) and the reflector (2), which rotates into a plurality about a horizontal axis of rotation and transverse to the optical axis Rotary positions is arranged adjustable, wherein the lateral surface (6) of the diaphragm shaft (4) for each rotational position has a focal line which generates a light-dark boundary of a light pattern, wherein the diaphragm shaft (4) is formed as an elongated hollow body, wherein the contour of the hollow body or the focal line is produced by generating an internal high pressure.
