Description

Die Erfindung betrifft einen Scheinwerfer für ein Fahrzeug, insbesondere für ein Zweirad mit einer Lichtquelle, die von einem ellipsoiden Reflektor umgeben ist, von dem die Lichtstrahlen zu einer Linse gelangen, durch die die Lichtstrahlen zur Fahrbahn hin austreten.The invention relates to a headlight for a vehicle, in particular for a two-wheeler with a light source which is surrounded by an ellipsoidal reflector, from which the light rays reach a lens through which the light rays emerge towards the road.

Es sind Scheinwerfer für Kraftfahrzeuge bekannt, die auf der Lichtaustrittsseite eine oder mehrere Linsen besitzen, um die optischen Eigenschaften des Scheinwerfers, insbesondere um die Grenze zwischen Hell- und Dunkelzone genauer zu gestalten. Hierzu wird auf die deutschen Offenlegungsschriften 2437249, 3311762 und 3340796 hingewiesen.Headlamps for motor vehicles are known which have one or more lenses on the light exit side in order to design the optical properties of the headlamp more precisely, in particular around the boundary between light and dark zones. In this regard, reference is made to the German laid-open documents 2437249, 3311762 and 3340796.

Aufgabe der Erfindung ist es, einen Scheinwerfer der eingangs genannten Art so zu verbessern, daß er in erhöhtem Maß zur Verkehrssicherheit des Fahrzeugs beiträgt.The object of the invention is to improve a headlight of the type mentioned in such a way that it contributes to an increased degree to the traffic safety of the vehicle.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Linse und/oder das austretende Hauptstrahlbündel nur einen Teil der Scheinwerferfrontfläche ausfüllt und mindestens eine Restfläche der Scheinwerferfrontfläche mindestens einen Rückstrahler aufweist, der von vorn auf die Scheinwerferfrontfläche auftreffendes Fremdlicht in die Einfallsrichtungen reflektiert.This object is achieved in that the lens and / or the emerging main beam fills only part of the headlight front surface and at least one remaining surface of the headlight front surface has at least one reflector which reflects external light impinging on the headlight front surface from the front in the directions of incidence.

Ein solcher Scheinwerfer übernimmt zusätzlich die Aufgabe eines Reflektors, d.h. von außen auf den Scheinwerfer auftreffendes Licht wird in die Einfallsrichtung zurückgeworfen, so daß sowohl bei eingeschaltetem als auch bei ausgeschaltetem Scheinwerfer die Frontseite des Fahrzeugs erhöht gesichert ist. Hierbei macht sich die erfindungsgemäße Lehre besonders vorteilhaft zu Nutze, daß bei Anordnung einer Linse, es möglich ist, das gesamte Licht der Lichtquelle durch die Linse austreten zu lassen und dennoch an der Vorderseite des Scheinwerfers genügend Fläche zu besitzen, um diese zusätzlich als Reflektor zu nutzen, ohne die Frontfläche des Scheinwerfers größer als üblich gestalten zu müssen. Der Scheinwerfer kann damit bei einfacher und preiswerter Bauweise kleine Außenabmessungen besitzen.Such a headlight also takes on the role of a reflector, i.e. Light incident on the headlight from outside is thrown back in the direction of incidence, so that the front of the vehicle is secured in an increased manner both when the headlight is switched on and when it is switched off. Here, the teaching according to the invention makes particularly advantageous use of the fact that when a lens is arranged, it is possible for all the light from the light source to emerge through the lens and still have enough space on the front of the headlight to additionally use it as a reflector use without having to make the front surface of the headlight larger than usual. The headlight can thus have small outer dimensions with a simple and inexpensive construction.

Besonders vorteilhaft ist es, wenn die Linse etwa mittig in der Scheinwerferfrontfläche angeordnet und ringförmig von dem Rückstrahler umgeben ist. Eine konstruktiv einfache Bauweise bei optisch ansprechendem Äußeren wird dann geschaffen, wenn zwei nach vorne wirkende Rückstrahler ober- und unterhalb der Linse angeordnet sind. Hierbei kann auch die Linse eine größere Breite als Höhe aufweisen und oberhalb und unterhalb der Linse je ein Rückstrahler in der Scheinwerferfrontfläche angeordnet sein.It is particularly advantageous if the lens is arranged approximately in the center of the headlight front surface and is surrounded in a ring by the reflector. A structurally simple construction with an optically appealing exterior is created when two forward-looking reflectors are arranged above and below the lens. In this case, the lens can also have a greater width than its height and a reflector can be arranged in the headlight front surface above and below the lens.

Es wird auch vorgeschlagen, daß zusätzlich zu nach vorne wirkenden(m) Rückstrahler(n) je ein nach rechts und links zur Richtung des Scheinwerfers seitlich wirkender Rückstrahler angeordnet ist. Damit besitzt dieser Scheinwerfer auch eine Signalwirkung zu den Seiten des Fahrzeugs hin. Vorzugsweise wird vorgeschlagen, daß die auf die Innen- bzw. Rückseite des Rückstrahlers auftreffenden Strahlen der Lichtquellen durch den Rückstrahler hindurchtreten und nach vorn bzw. zur Seite austreten. Damit wird die Signalwirkung des Scheinwerfers, von anderen Verkehrsteilnehmern gesehen zu werden, wesentlich erhöht.It is also proposed that, in addition to the forward reflecting reflector (s), a reflecting element laterally acting to the right and left to the direction of the headlight is arranged. This headlight also has a signal effect to the sides of the vehicle. It is preferably proposed that the rays of the light sources striking the inside or back of the reflector pass through the reflector and exit to the front or to the side. This significantly increases the signal effect of the headlamp to be seen by other road users.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in einem axialen Schnitt dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing in an axial section and is described in more detail below.

Der Scheinwerfer ist insbesondere bei Kraftfahrzeugen und Fahrrädern verwendbar und weist eine ellipsoiden Reflektor 1 bzw. eine ellipsoide spiegelnde Fläche auf, in deren Brennpunkt oder zu dem Brennpunkt versetzt eine Lichtquelle, insbesondere eine Glühbirne befestigt ist. Die von der Lichtquelle 2 ausgehenden Strahlen gelangen an der Vorderseite des Scheinwerfers durch eine Linse aus Glas oder durchsichtigem Kunststoff, die als Refraktor (Streulinse) wirkt und konkav geformt ist. Die Linse 3 richtet damit die Lichtstrahlen etwa parallel zueinander aus, so daß dieses Bündel paralleler Lichtstrahlen die Straße vor dem Fahrzeug ausleuchtet.The headlight can be used in particular in motor vehicles and bicycles and has an ellipsoidal reflector 1 or an ellipsoidal reflecting surface, in the focal point or of which focal point a light source, in particular a light bulb, is attached. The rays emanating from the light source 2 reach the front of the headlight through a lens made of glass or transparent plastic, which acts as a refractor (diffusing lens) and has a concave shape. The lens 3 thus aligns the light rays approximately parallel to one another, so that this bundle of parallel light rays illuminates the road in front of the vehicle.

Die senkrechte, insbesondere runde, ovale oder rechteckige etwa ebene Vorderfläche 4 wird nur zu einem Teil von der Linse 3 ausgefüllt. Entweder benötigt die Linse 3 nur einen mittleren, insbesondere runden Bereich der Vorderfläche, so daß um die Linse 3 herum eine ringförmige Restfläche 5 verbleibt, oder aber die Linse 3 ist länglich gestaltet, d.h. ihr Querschnitt ist über ihre waagerechte Länge gleichbleibend und es bleiben oberhalb und unterhalb der Linse 3 kreisabschnittförmige Restflächen 5.The vertical, in particular round, oval or rectangular approximately flat front surface 4 is only partially filled by the lens 3. Either the lens 3 only needs a central, in particular round, area of the front surface, so that an annular residual surface 5 around the lens 3 remains, or the lens 3 is elongated, ie its cross-section is constant over its horizontal length and there are residual areas 5 in the form of circular sections above and below the lens 3.

In beiden Fällen sind in oder auf diesen Restflächen 5 Rückstrahler 6 (Retroreflektoren, Katzenaugen, Trippelprisma) angeordnet bzw. befestigt, die das auf die Vorderseite des Scheinwerfers auffallende Fremdlicht in die Einfallsrichtung reflektieren.In both cases, 5 reflectors 6 (retroreflectors, cat eyes, triple prism) are arranged or fastened in or on these remaining surfaces, which reflect the external light striking the front of the headlight in the direction of incidence.

Darüberhinaus können die Rückstrahler 6 durchlässig sein für von der Lichtquelle 2 ausgehende Strahlen, so daß auch bei nicht von außen auftreffendem Fremdlicht die Rückstrahler 6 hell, insbesondere weiß leuchten. Ferner können an den Seitenflächen des Scheinwerfers weitere Rückstrahler befestigt sein.In addition, the reflectors 6 can be transparent to rays emanating from the light source 2, so that the reflectors 6 shine brightly, in particular white, even when external light is not incident from outside. Furthermore, further reflectors can be attached to the side surfaces of the headlamp.
