Die Erfindung betrifft ein Fahrzeuglicht.The invention relates to a vehicle light.

Erfindungsgemäß ist ein Fahrzeuglicht vorgesehen, das gekennzeichnet ist durch einen gewölbten Reflektor und einen im gewölbten Reflektor angeordneten elektrischen Glühfaden, der eine Achse hat, welche sich quer in bezug auf eine Hauptachse des Reflektors erstreckt und die in bezug auf eine waagrechte Ebene schräg*gestellt ist, in der die Hauptachse liegt.According to the invention, a vehicle light is provided that is identified is through a curved reflector and one in the curved reflector arranged electric filament having an axis which extends transversely with respect to a major axis of the reflector and which is shown in FIG is inclined * with respect to a horizontal plane in which the main axis lies.

Vorzugsweise ist der Glühfaden unte„ einem Winkel von zwischen JO una 45 schräggestellt, bezogen auf die waagrechte Ebene.Preferably the filament is at an angle of between JO and a 45 inclined, based on the horizontal plane.

Vorteilhafterweise erstreckt sich die Achse des elektrischen Glühfadens unter einem rechten winkel in bezug auf die Hauptachse des Reflektors.Advantageously, the axis of the electric filament extends at a right angle with respect to the major axis of the reflector.

Das Fahrzeuglicht kann weiter eine optische Projektionseinrichtung aufweisen, die zum Empfangen und zum optischen Kodifizieren des Musters des Lichtes eingerichtet ist, welches im Gebrauch von dem gewölbten Reflektor kommt.The vehicle light can also have an optical projection device, arranged to receive and optically encode the pattern of light which, in use, comes from the domed reflector comes.

Der elektrische Glühfaden kann ein herkömmlicher Metallglühf&.ien oder ein Quarzhealogen-Glühfaden sein.The electric filament can be a conventional metal filament or be a quartz helical filament.

Zwuckmäfiigerweisc ist ein Lchina vor dein ht-i'lektor zum Modifizieren des 1-iusters des Lichts vorgesehen, das im Gebrauch vom Reflektor koimiit. Der Schirm kann zwischen de:u reflektor und der optischen i'rojektionseinrich-Tucked away, there is a china in front of the ht-i'lector to modify the pattern of light that collides with the reflector in use.

Die optische Projektionseinrichtung kann eine Linse oder Linsen sein, oder es kann sich um einen gekrümmten Reflektor, z.B. um einen Parabolspiegel, handeln.The optical projection device can be a lens or lenses, or it can be a curved reflector, e.g. a parabolic mirror, Act.

Die Schrägstellung des elektrischen FGlühfadens in der vorstehend beschriebenen Weise„ermgölicht eine Richtung des Bildes des Glühfadens längs eines Bordsteins an der Straßenseite, was die Charakteristiken des Lichts verbessert, was die Sicht des Fahrers anbelangt.The inclination of the electric filament in the one described above Way “allows one direction of the image of the filament along a curb on the side of the road, which improves the characteristics of the light as far as the driver's view is concerned.

Die Erfindung ist nachstehend an Hand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert. In der Zeichnung sind:The invention is shown below on the basis of an exemplary embodiment Explained in more detail with reference to the drawing. In the drawing are:

Pig. 1 eine schematische Ansicht eines Fahrzeuglichts nach der Erfindung undPig. 1 is a schematic view of a vehicle light according to the invention and

Fig. 2 eine schematische Vorderansicht eines Lichtreflektors, der in dem in Fig. 1 gezeigten Licht verwendet wird.Fig. 2 is a schematic front view of a light reflector in the light shown in Fig. 1 is used.

Das Fahrzeuglicht, das zur Verwendung als ein I'ahrzeugscheinwerfer mit Abblendemöglichkeit vorgesehen ist, weist einen allgemein gewölbten Reflektor 10, eine allgemein rechteckige Konve;:linse 11 im axialen Abstand vom Reflektor 10 mit einer Hauptachse in der Hauptachse des Reflektors 10 und einen Sei irm 12 auf, der sich im rechten Winkel in bezug auf die Hauptachse des Reflektors 10 erstreckt. In dem Reflektor 10 befindet sich in einer inneren Brennebene desselben ein V/olfram-Glühf aden 14» der sich im reohten Kinkel in bezug auf die Hauptachse des Reflektors 10 erstreckt und der eine Achse hat, welche unter einem Winkel zu einer waagtrechten Ebene steht, in der die Hauptachse des Reflektors liegt. Dieser Winkel kann zwischen 50° und 45° betragen, im vorliegenden Ausführungsbeispiel beträgt er aber 55 ·The vehicle light designed for use as a vehicle headlight with Dimming is provided, has a generally curved reflector 10, a generally rectangular convex;: lens 11 at an axial distance from the reflector 10 with a main axis in the main axis of the reflector 10 and a Sei irm 12 which is at right angles with respect to the Main axis of the reflector 10 extends. A tungsten filament 14 is located in an inner focal plane of the reflector 10 extends in the reohten angle with respect to the main axis of the reflector 10 and which has an axis which is at an angle to a horizontal plane in which the main axis of the reflector lies. That angle can be between 50 ° and 45 °, but in the present embodiment it is 55

Der Sohirm 12 hat einen oberen Rand I5, der unmittelbar unter der Hauptachse des Reflektors 10 liegt.The screen 12 has an upper edge 15 which is immediately below the main axis of the reflector 10 is located.

vom Schirm 12 modifiziert, ehe es durch die Linse 11 geht, und zwar derart, daß ein oberer Teil des Lichtmusters, das anderenfalls von der Linse 11 ausgehen würde, abgeschnitten wird. Das Vorsehen des Schirms 12 ermgöglicht die Verwendung des Lichts als ein sogenanntes:abgeblendeteer Scheinwerfer an einem Fahrzeug. Die Winkelstellung des Glühfadens I4 in bezug auf die Hauptachse des Heflektors in der vorstehend beschriebenen Weise ermöglicht ein Richten des Bilds des Glühfadens, das vom Licht geworfen wird, längs eines Bordsteins einer Straße, wenn das Licht an einem Kraftfahrzeug angebaut ist. Ein Richten des Glühfadens auf diese Weise dürfte die Sichtbarkeit des Bordsteins verbessern, zumindest was den Pahrer des Fahrzeugs anbelangt.modified by the screen 12 before it goes through the lens 11 in such a way that that an upper part of the light pattern, that otherwise of the lens 11 would run out, is cut off. The provision of the screen 12 enables the use of the light as a so-called: dimmed Headlights on a vehicle. The angular position of the filament I4 with respect to the major axis of the yeast deflector in that described above Manner enables the image of the filament cast by the light to be directed along a curb of a road when the light is on Motor vehicle is attached. Straightening the filament this way should improve the visibility of the curb, at least what the pahrer of the vehicle.

Das vorstehend beschriebene Licht ist besonders zur Verwendung in Verbindung mit einem gekrümmten Reflektor geeignet, der bereits vorgeschlagen worden ist.The light described above is particularly for use in conjunction suitable with a curved reflector which has already been proposed.

Der Ausdruck "waagrechte Ebene", wie er hier in bezug auf die Lageanordnung des Glühfadens in bezug auf den Reflektor verwendet wird, bedeutet die Lageanordnung des Glühfadens, wenn der Reflektor eine Orientierung einnaimmt, die aer entspricht, für die er ausgelegt worden ist.The term "horizontal plane" as used here in relation to the positional arrangement of the filament is used in relation to the reflector means the positional arrangement of the filament when the reflector has an orientation takes which corresponds to aer for which it was designed.
