Description

Scheinwerfer für Kraftfahrzeuge Die Erfindung bezieht sich auf einen Scheinwerfer für Kraftfahrzeuge, der auf der Begegnungsseite angeordnet ist und die Straße in der Richtung nach vorn, rechts und nach hinten erleuchtet.Headlights for motor vehicles The invention relates to a Headlight for motor vehicles, which is arranged on the meeting side and the road is illuminated in the direction of the front, the right and the rear.

Bei bekannten Scheinwerfern dieser Art, die dazu bestimmt sind, das Aneinandervorbeifahren von Kraftfahrzeugen bei Dunkelheit zu erleichtern, wird die Beleuchtung durch zwei gesonderte Lichtquellen und zwei verschiedene Reflektoren erzeugt.In known headlights of this type, which are intended to The will make it easier for motor vehicles to pass each other in the dark Illumination by two separate light sources and two different reflectors generated.

Die Erfindung bezweckt, einen baulich wesentlich vereinfachten Scheinwerfer zu schaffen, der den gleichen Zweck erfüllt und zu einem billigeren Preise hergestellt und auf den Markt gebracht werden kann.The aim of the invention is to provide a headlight that is structurally much simpler to create that serves the same purpose and is manufactured at a cheaper price and can be brought to market.

Die Erfindung besteht darin, daß der Scheinwerfer mit zwei entgegengesetzt zueinander gerichteten, sich winklig durchdringenden parabolischen -Reflektoren versehen ist, die einen gemeinsamen Brennpunkt besitzen, der im Schnittpunkt der beiden Längsmittelachsen der Reflektoren auf der durch die Durchdringungslinie gelegten Ebene liegt.The invention consists in that the headlight is opposed to two Parabolic reflectors directed towards each other and penetrating each other at an angle is provided, which have a common focal point at the intersection of the both longitudinal center axes of the reflectors on the one laid by the penetration line Level lies.

Ein weiteres Kennzeichen der Erfindung besteht darin, daß die den einen Reflektor abschließende Scheibe a1'§ Träger für eine beiden Reflektoren gemeinsame Lichtquelle diente, die genau in den Brennpunkt der beiden Reflektoren eingestellt werden kann.Another feature of the invention is that the a reflector closing disc a1'§ carrier for a two reflectors common The light source was used, which was set exactly in the focal point of the two reflectors can be.

Eine nach diesen Vorschlägen gebaute Vorrichtung ist auf der Zeichnung in einem Ausführungsbeispiel dargestellt, und zwar zeigt die Abbildung den Scheinwerfer im Querschnitt. Der Scheinwerfer besteht aus zwei parabolischen Reflektoren A und B mit den Längsmittelachsen x und y. Die Reflektoren sind mit ihren Scheitelpunkten gegeneinander gerichtet und durchdringen sich in einem Winkel derart, daß sie einen gemeinsamen Brennpunkt F erhalten, der im Schnittpunkt der beiden Längsmittelachsen x, y und auf der durch- -die Durchdringungslinie gelegten Ebene liegt.A device built according to these proposals is shown in the drawing in an exemplary embodiment, namely the figure shows the headlight in cross section. The headlight consists of two parabolic reflectors A and B with the longitudinal central axes x and y. The reflectors are directed towards each other with their vertices and penetrate each other at an angle in such a way that they receive a common focal point F which lies at the intersection of the two longitudinal central axes x, y and on the plane through which the penetration line passes.

Die Innenflächen der Reflektoren sind poliert, so daß sie gut reflektieren.The inner surfaces of the reflectors are polished so that they reflect well.

Im gemeinsamen Brennpunkt dieser beiden Reflektoren ist eine elektrische Glühlampe L angeordnet, die mittels eines Halters C gehalten wird. Der Halter C besteht aus zwei Backen, die in einer der Länge nach geschlitzten Büchse M herausnehmbar befestigt sind. Eine mit Schraubengewinde versehene überwurfmutter E, die durch Zapfen D in ihrer Lage gesichert ist, dient zur Befestigung des Halters C und der Buchse M an der Scheibe G bzw. an einem die Scheibe G durchgreifenden Stopfen ?' derart, daß der Glühfaden sich genau im Brennpunkt F der beiden Reflektoren A und B befindet.An electric incandescent lamp L, which is held by means of a holder C, is arranged at the common focal point of these two reflectors. The holder C consists of two jaws that are removably attached in a sleeve M slotted lengthways. A screw-threaded union nut E, which is secured in its position by pin D, is used to fasten the holder C and the socket M to the washer G or to a plug that extends through the washer G? ' in such a way that the filament is exactly in the focal point F of the two reflectors A and B.

Eine gegen eine am Fuß der Lampe befindliche Scheibe H drückende Feder 12 hält die Glühlampe L in ihrer Arbeitsstellung .und in Kontakt reit den Polen der elektrischen Zuleitungl(. Diese ist auf ihrem Wege über die Scheibe G von einem dünnen Metallrohr N umschlossen.A spring pressing against a disk H located at the base of the lamp 12 holds the incandescent lamp L in its working position and rides the poles in contact the electrical supply line (. This is on its way over the disk G of a thin metal tube N enclosed.

Beide Reflektoren A und B nebst ihren Scheiben G und S werden in einem Gehäuse P gehalten, das an einem Tragarm Q befestigt ist. Der Arm ist an einer geeigneten Stelle des Wagenaufbaus angebracht. Die Scheibe S wird durch einen Klemmring V gehalten, der mit einem undurchsichtigen Blendschirm W versehen ist.Both reflectors A and B together with their disks G and S are in one casing P held, which is attached to a support arm Q. The arm is attached to a suitable place on the car body. The disk S is through a clamping ring V held, which is provided with an opaque screen W. is.

Die Wirkungsweise der Vorrichtung ist wie folgt Der Scheinwerfer wird seitlich links oben an den Wagenaufbau angebracht, wobei die Scheibe 0 in die Fahrtrichtung zeigt.The operation of the device is as follows: The headlamp is Attached to the top left of the car body, with the disk 0 facing the direction of travel shows.

Wenn zwei in dieser Weise ausgerüstete Kraftwagen sich bei Nacht begegnen, blen-, den die Führer die vorderen (Haupt-) Scheinwerfer ab und lassen gleichzeitig, die oben beschriebenen Scheinwerfer aufleuchten.When two vehicles equipped in this way meet at night, dazzle the leaders off the front (main) headlights and leave at the same time, the headlights described above come on.

Der ReflektorA wirft dann die Strahlen auf die Straße vor dem Kraftwagen, und zwar zur rechten Seite auf eine genügend große Entfernung, so daß der Führer etwaigen Hindernissen bequem ausweichen kann.The reflector A then throws the rays onto the road in front of the vehicle, and to the right at a sufficiently great distance so that the Führer can easily avoid any obstacles.

Der ReflektorB strahlt das Licht nach hinten zu aus und beleuchtet somit die Fahrstraße für den Führer des entgegenkommenden Fahrzeuges, so daß auch dieser etwaige Hindernisse, die hinter dem anderen Fahrzeuge sind, unterscheiden kann. Der undurchsichtige Schirm W dient dazu, ein Blenden des Führers des mit dem Scheinwerfer gemäß der Erfindung ausgerüsteten Kraftwagens zu verhindern.The reflector B emits the light to the rear and illuminates thus the route for the driver of the oncoming vehicle, so that too this distinguish any obstacles that are behind the other vehicles can. The opaque screen W serves to dazzle the guide of the with the To prevent headlights according to the invention equipped motor vehicle.
