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. A headlamp that is infinitely variable in brightness is adjustable, contains a reflector (10) for generation a light beam emanating from a light source (18). A diaphragm (22) is in the beam path of the light beam arranged. To change the illumination of the aperture is an adjusting device (28 ... 36) for relative adjustment the light source (18) along the optical axis (16) of the Headlamp to change the used Cross section of the light beam in the plane of the diaphragm (22) provided.
