Abstract

Ein Scheinwerfer, der in seiner Helligkeit stufenlos regelbar ist,enthält einen Reflektor(10) zur Erzeugung eines von einer Lichtquelle (18) ausgehenden Lichtbündels. Im Strahlengang des Lichtbündels ist eine Blende (22) angeordnet. Zur Veränderung der Ausleuchtung der Blende ist eine Stellvorrichtung (28...36) zur Relativverstellung der Lichtquelle (18)längs der optischen Achse (16) des Scheinwerfers zwecks Veränderung des ausgenutzten Querschnitts des Lichtbündels in der Ebene der Blende (22) vorgesehen.
