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.
