Abstract

Ein Scheinwerfer weist einen gekrümmten Reflektor (1, 1') und eine innerhalb des durch den Reflektor (1, 1') gebildeten Hohlraums angeordnete Lampe (2, 2') auf. Die Lampe (2, 2') und der Reflektor (1, 1') sind in Richtung der optischen Hauptachse des Scheinwerfers relativ zueinander bewegbar. In Abstrahlrichtung vor dem Reflektor (1, 1') ist eine Sammellinse (5) angeordnet. Zwischen dem Reflektor (1, 1') und der Sammellinse (5) befindet sich eine Zerstreuungslinse (6).

Figure 00000001
A headlight has a curved reflector (1, 1 ') and a lamp (2, 2') arranged inside the cavity formed by the reflector (1, 1 '). The lamp (2, 2 ') and the reflector (1, 1') can be moved relative to one another in the direction of the main optical axis of the headlight. A converging lens (5) is arranged in front of the reflector (1, 1 ') in the direction of radiation. A diverging lens (6) is located between the reflector (1, 1 ') and the converging lens (5).
