Description

Scheinwerfer an Fahrzeugen. Die Erfindung betrifft eine Abblendvorrichtung 'für Scheinwerfer an Fahrzeugen, bei der die vom Reflektor des Scheinwerfers ausgehenden Lichtstrahlen durch drehbare Prismen wahlweise nach, einer beliebigen Seite optisch gebrochen werden.Headlights on vehicles. The invention relates to a dimming device '' for headlights on vehicles in which those emanating from the reflector of the headlight Light beams through rotatable prisms optionally to any side optically to get broken.

Die Erfindung besteht darin, daß der Scheinwerfer 'durch nur eine drehbare Prismenscheibe vorn abgedeckt und zugleich schuiach nach turn geneigt ist, so daß die Lichtstrahlen in der einen Lage der Prismenscheibe wagerecht heraustreten, in der um r 8o° gedrehten Lage 'der Prismenschebe aber schräg 'auf den Erdboden geworfen werden. Die `Zeichnung veranschaulicht eine Ausführungsform.The invention is that the headlight 'by only one rotatable prismatic disc is covered at the front and at the same time tilted towards the turn, so that the light rays emerge horizontally in one position of the prismatic lens, in the r 80 ° rotated position 'of the prismatic but obliquely' on the ground to be thrown. The `drawing illustrates one embodiment.

Die drehbare prisrnatische Scheibe ¢o bricht 'die vom Reflektor ausgehenden LichtstraMen "in der einen Lage nach oben, 5.n der anderen, 'um i 8o° gedrehten Lage nach unten. Der Scheinwerfer ist in senkrechter Ebene etwas 'nach vorn geneigt angebracht, so daß die Lichtstrahlen zwischen Reflektor und Prismenscheibe 4o etwas nach unten gehen. Sie werden dann durch die Scherbe 40 so weit nach oben gebrochen, daß sie horizontal gerichtet 'sind (Abb. a). Zum Abblenden wird die 'Scheibe 40 um igo° gedreht, so daß nun die Lichtstrahlen von der Scheibe 4o noch weiter mach unten gebrochen werden (Abb. 3).The rotating prismatic disc "o" breaks the one emanating from the reflector LichtstraMen "in one position upwards, 5.n the other, rotated by i 80 ° Position down. The headlight is inclined slightly forward in the vertical plane attached so that the light rays between the reflector and prismatic lens 4o something go downstairs. They are then broken up so far by the shard 40, that they are directed horizontally '(Fig. a). For stopping down, the 'disk 40 rotated by igo °, so that now the light rays from the disk 4o go even further be broken at the bottom (Fig. 3).

PATENTANSPRUCH: Scheinwerfer an Fahrzeugen, bei dem die vom Reflektor des Scheinwerfers ausgebenden Lichtstrahlen durch drehbare Prismen wahlweise nach einer beliebigen Seite optisch gebrochen werden, dadurch gekennzeichnet, daß der Scheinwerfer durch nur eine einzige drehbare Prismenscheibe vorn abgedeckt und zugleich schwach nach vorn geneigt ist, so daß die Lichtstrahlen in der einen Lage der Prismenscheibe wagerecht heraustreten, in der um i 8 o° gedTehten Lage der P rismenscheibe aber schräg auf den Erdboden geworfen werden. PATENT CLAIM: Headlights on vehicles, in which the light rays emitted by the reflector of the headlight are optically refracted by rotatable prisms optionally to any side, characterized in that the headlight is covered at the front by only a single rotatable prismatic disk and at the same time is slightly inclined forwards, see above that the light rays emerge horizontally in one position of the prismatic disc, but in the position of the prismatic disc rotated by i 8 o ° they are thrown obliquely onto the ground.
