Description

Lichtstrahlenrichter Die Erfindung betrifft eine Vorrichtung, durch welche die Lichtstrahlen von Scheinwerfern, insbesondere Autolampen, in ein begrenztes Strahlgebiet gestrahlt werden. Derartige Einrichtungen sind bekannt als Lichtstrahlenrichter für Kraftfahrzeugscheinwerfer, insbesondere für 1,Tebelscheinwerfer, mit in den Strahlengang eingebauten, lichtrichtenden, drehbaren Lamellen. Sie haben jedoch den Nachteil, daß sie bei wirksamer Abblendung eine allzu geringe Scheinwerferwirkung haben.Light beam straightener The invention relates to a device through which the light rays from headlights, especially car lamps, in a limited Radiation area are blasted. Such devices are known as light beam directors for motor vehicle headlights, in particular for 1, fog lights, with in the Light-directing, rotatable slats built into the beam path. However, you have the disadvantage that they have too little headlight effect with effective dimming to have.

Die Erfindung besteht darin, daß die in ein vor dem Scheinwerfer befestigtes konisches Gehäuse eingesetzten Lamellen mit Hilfe eines durch den Fahrtwind beaufschlagten Regelflügels und einer Rückstellfeder in Abhängigkeit von der Fahrgeschwindigkeit einstellbar sind.The invention consists in that in a fixed in front of the headlight conical housing inserted lamellae with the help of one acted upon by the airstream Regulating vane and a return spring depending on the driving speed are adjustable.

Durch den Lichtstrahlenrichter nach der Erfindung wird erreicht, daß bei geringer Geschwindigkeit des Wagens die aus Lamellen bestehenden Jalousien in dem Gehäuse nach unten gerichtet werden, wodurch die Strahlen auf kurze Entfernung auf den Boden fallen. Das entspricht den Erfordernissen bei starkem Nebel. Bei schnellerem Tempo stellt der Windflügel unter dem Einflug der Windströmung die Jalousien in eine sich bei größter Geschwindigkeit der horizontalen Lage nähernde Richtung ein, was der Fahrt bei klarem Wetter entspricht.By the light beam director according to the invention it is achieved that at low speed of the carriage, the blinds consisting of slats in the housing are directed downwards, reducing the rays at a short distance fall to the ground. This corresponds to the requirements in heavy fog. At faster The speed of the wind blade moves the blinds in as the wind blows in a direction approaching the horizontal position at maximum speed, which corresponds to driving in clear weather.

In der Zeichnung ist die Erfindung in einer Ausführungsform beispielsweise dargestellt.In the drawing, the invention is in one embodiment for example shown.

In Fig. 1 und 2 ist 1 die Lampe, 2 das konische Lampengehäuse, 3 sind die Jalousien, 4 sind die Lamellenachsen, die auf beiden Seiten der Lampe drehbar gelagert sind, 5 ist das Steuergestänge für die Jalousien 3, welches an dem Flügel 6 befestigt ist, der unter der Einwirkung des Luftstromes steht. 7 ist die Befestigungsstütze für den Flügel 6, auf welcher derselbe drehbar gelagert ist. Die Steuerung mittels des Flügels 6 kann beliebig auf oder auch seitlich an dem Gehäuse angeordnet werden. 8 ist eine Feder, welche über das Steuergestänge 5 die Jalousien 3, im Stillstand und bei geringer Geschwindigkeit, in eine die Strahlrichtung nach unten leitende Stellung bringt. Bei Geschwindigkeitssteigerung wird infolge der Luftströmung gegen den Flügel 6 der Federdruck überwunden und so die Jalousien mehr oder weniger in die horizontale Lage gebracht.In Figures 1 and 2, 1 is the lamp, 2 is the conical lamp housing, 3 are the blinds, 4 are the slat axles that rotate on either side of the lamp are stored, 5 is the control linkage for the blinds 3, which is on the wing 6 is attached, which is under the action of the air flow. 7 is the mounting bracket for the wing 6, on which the same is rotatably mounted. The control by means of of the wing 6 can be arranged as desired on or on the side of the housing. 8 is a spring which, via the control linkage 5, controls the blinds 3 at a standstill and at low speed, in a downward direction of the jet Position. As the speed increases, the air flow counteracts the wing 6 overcome the spring pressure and so the blinds more or less in brought the horizontal position.
