Abstract

Vorgeschlagen wird ein Abblendlicht-/Fernlichtscheinwerfereinheit für ein Kraftfahrzeug, mit zwei unterschiedlich reflektierenden Reflektorabschnitten (2,6), von denen einer auf eine Projektionslinse (5) und der andere an dieser vorbei reflektiert und wobei zwischen einer einzigen Lichtquelle (3) und der Projektionslinse (5) eine Blende (4) angeordnet ist, mit dem Kennzeichen, daß der eine Reflektorabschnitt ein Abblendlichtreflektor (2) ist, der über eine feste Hell-/Dunkelblende (4) auf die Projektionslinse (5) reflektiert und der andere ein vom Abblendlichtreflektor (2) getrennter Fernlichtreflektor (6) ist, zwischen dem und der Lichtquelle (3) eine, insbesondere parallel zur optischen Achse bewegliche, Streifenblende (7) zur wahlweisen Abschattung des Fernlichteflektors (6) gegenüber der Lichtquelle (3) vorgesehen ist.

Figure 00000001
A low-beam / high-beam headlight unit for a motor vehicle is proposed, with two differently reflecting reflector sections (2,6), one of which reflects onto a projection lens (5) and the other past it and between a single light source (3) and the projection lens (5) a diaphragm (4) is arranged, with the characteristic that the one reflector section is a low beam reflector (2) which reflects on the projection lens (5) via a fixed light / dark diaphragm (4) and the other one from the low beam reflector (2) separate high beam reflector (6), between which and the light source (3) a, in particular movable parallel to the optical axis, a strip diaphragm (7) is provided for optional shading of the high beam reflector (6) relative to the light source (3).
