Description

Scheinwerfer für Kraftwagen Die Erfindung bezieht sich auf blendungsfreie Autoscheinwerfer mit einem über der Lichtquelle liegenden Schirm in der bekannten Anordnung, bei der keine Strahlen sich oberhalb einer durch die Lichtquelle hindurchgehenden Horizontalebene erheben. Ihr Ziel ist, die Reichweite des Scheinwerfers und seine Stärke zu erhöhen, und zwar in einer ganz bestimmten Richtung, ohne daß dabei die Verteilung der anderen Strahlen nach der Seite oder gegen den Boden beeinflußt wird.Headlights for motor vehicles The invention relates to glare-free Car headlights with a screen lying over the light source in the known Arrangement in which no rays are above one passing through the light source Elevate horizontal plane. Your goal is the range of the headlight and its To increase strength, in a very specific direction, without affecting the Distribution of the other rays to the side or against the ground is influenced.

Die Erfindung besteht im wesentlichen darin, daß in der Lichtaustrittsöffnung des Scheinwerfers die Hälfte einer Linse angeordnet wird, und zwar die untere Hälfte einer Linse, deren obere Hälfte durch einen Mittelschnitt weggeschnitten ist. Diese Linsenhälfte wird derart mit dem Scheinwerfer verbunden, daß sie einen Teil des Lichtbündels erfaßt und weit nach vorn wirft, so daß eine bestimmte, vom Wagen entferntere Stelle mit größerer Helligkeit als ihre Umgebung beleuchtet wird.The invention consists essentially in that in the light exit opening of the headlight half of a lens is arranged, namely the lower half a lens, the upper half of which is cut away by a central cut. These Lens half is connected to the headlight in such a way that it forms part of the The bundle of light is captured and thrown far forward, so that a certain one more distant from the car Place with greater brightness than its surroundings are illuminated.

Der Gegenstand der Erfindung ist in der Zeichnung in mehreren Ausführungsformen beispielsweise veranschaulicht.The object of the invention is shown in the drawing in several embodiments for example illustrated.

Abb. z stellt einen schematischen Schnitt durch einen Scheinwerfer dar.Fig. Z shows a schematic section through a headlight represent.

Abb. z ist ein Grundriß der Abb. i.Fig. Z is a plan view of Fig. I.

Abb. 3 zeigt einen Scheinwerfer mit einem Reflektor, der die Lampe auf dem größeren Teil ihres Umfanges umschließt: Abb.4 veranschaulicht die Ausführungsform eines blendungsfreien Scheinwerfers in Verbindung mit einem kleinen parabolischen Reflektor.Fig. 3 shows a headlight with a reflector, which is the lamp encloses on the larger part of its circumference: Figure 4 illustrates the embodiment a glare-free headlight in conjunction with a small parabolic one Reflector.

Wie Abb. i zeigt, ist ein reflektierender, die Lichtquelle 2 in bekannter Weise zum Teil abblendender Schirm. An dem Rande des Schirmes r befindet sich eine halbe Linse 3, die einen Teil der Strahlen, welche unmittelbar von der Lichtquelle kommen, sammelt und sie in der Achsrichtung des Scheinwerfers weit nach vorn wirft. Auf diese Weise wird die Fahrstraße des Autos auf weite Entfernung hin stark beleuchtet, ohne daß eine Blendung entgegenkommender Passanten und Fahrzeuge zu befürchten wäre.As Fig. I shows, is a reflective, the light source 2 in known Way partially dimming screen. At the edge of the screen r there is one half lens 3, which covers part of the rays emanating directly from the light source come, collects and throws them far forward in the axial direction of the headlight. In this way, the road of the car is strongly illuminated from a long distance, without fear of dazzling oncoming passers-by and vehicles.

In Abb. 4 ist eine Ausführungsform der Erfindung dargestellt, die durch einen kleinen parabolischenReflektor ergänzt ist, der gleichachsig mit der Linsenhälfte hinter der Lampe angeordnet ist, um die Strahlen der Lichtquelle auf die Linse zu konzentrieren.In Fig. 4 an embodiment of the invention is shown, the is supplemented by a small parabolic reflector coaxial with the Lens half is arranged behind the lamp, to the rays of the light source on focus the lens.

In den Darstellungen sind zwar ausschließlich sphärische Linsen wiedergegeben, jedoch können zur Erzielung des gewünschten Erfolges auch Linsenhälften von anderen beliebigen Arten verwendet werden.Only spherical lenses are shown in the illustrations, however, lens halves from others can also be used to achieve the desired result any types can be used.

Die Entfernung der Lichtquelle von der Linsenhälfte ist gegebenenfalls veränderlich; die Linsenhälfte kann auf jede beliebige Art und Weise befestigt werden, die ihre Einstellung und Reinigung gestattet.The distance of the light source from the lens half is optional changeable; the lens half can be attached in any way, which allows their adjustment and cleaning.
