Abstract

Vorgestellt wird ein Kraftfahrzeugscheinwerfer (10), mit einem einander paarweise benachbart angeordnete Lichtquellen (16.1, 16.2, 16.3) aufweisenden Lichtquellenfeld (16), wobei jede der Lichtquellen dazu eingerichtet ist und mit einem Sammellinsenfeld (22), das für jede der wenigstens drei Lichtquellen genau eine Sammellinse (22.1, 22.2, 22.3) aufweist, die der jeweiligen Lichtquelle dadurch zugeordnet ist, dass eine Lichteintrittsfläche dieser Sammellinse in dem von dieser Lichtquelle ausgehenden Lichtbündel liegt. Der Scheinwerfer zeichnet sich dadurch aus, dass er wenigstens eine Blende (24) aufweist, die auf der Lichteintrittsflächenseite von zwei einander direkt benachbart angeordneten Sammellinsen so angeordnet ist, dass sie die Lichteintrittsfläche der einen der zwei Sammellinsen gegen Licht abschattet, die der anderen der zwei einander direkt benachbart angeordneten Sammellinsen zugeordnet ist.

Disclosed is a motor vehicle headlight (10) having a pair of adjacent adjacent light sources (16.1, 16.2, 16.3) having light source field (16), each of the light sources is arranged and with a collecting lens array (22), for each of the at least three light sources exactly one converging lens (22.1, 22.2, 22.3), which is associated with the respective light source in that a light entrance surface of this converging lens is located in the outgoing light beam from this light source. The headlamp is characterized in that it comprises at least one aperture (24) which is arranged on the light entrance surface side of two directly adjacent collecting lenses so that it shades the light entrance surface of the one of the two converging lenses against light, the other of the two is associated with each other directly adjacent arranged collecting lenses.
