II. Darstellung der Erfindung II. Presentation of the invention

Es ist die Aufgabe der Erfindung, eine gattungsgemäße Scheinwerferlampe mit einem vereinfachten Sockelaufbau bereitzustellen.It is the object of the invention to provide a generic headlamp with a simplified base structure.

Die erfindungsgemäßen Scheinwerferlampen wie beansprucht zeichnen sich gegenüber den bekannten gattungsgemäßen Lampen dadurch aus, daß der Sockelflansch mindestens drei entlang des Sockelflanschumfangs angeordnete Laschen besitzt, die senkrecht zur Sokkelflanschebene federnd ausgebildet sind. Diese Laschen ermöglichen zusammen mit den Referenznasen eine Befestigung der erfindungsgemäßen Scheinwerferlampe in einer Lampenmontageöffnung des Scheinwerfers. Der Rand der Lampenmontageöffnung des Scheinwerfers ist nach dem Einsetzen der Lampe klemmend zwischen den Referenznasen und den erfindungsgemäßen Laschen fixiert. Ein Dichtungsring und ein gasdicht ausgebildetes Kunststoffsockelunterteil sind nicht erforderlich, wenn der Scheinwerfer selbst mit Dichtungsmitteln zum gasdichten Verschluß der Lampenmontageöffnung ausgestattet ist.The headlight lamps according to the invention as claimed are distinguished from the known generic lamps in that the base flange has at least three tabs arranged along the base flange circumference, which are designed to be resilient perpendicular to the bottom plane of the flask. These tabs allow together with the reference lugs attachment of the headlight lamp according to the invention in a lamp mounting opening of the headlamp. The edge of the lamp mounting opening of the headlamp is fixed by clamping the lamp between the reference lugs and tabs according to the invention after insertion of the lamp. A sealing ring and a gas-tight trained plastic base are not required when the headlamp itself is equipped with sealing means for gas-tight closure of the lamp mounting hole.

Vorteilhafterweise sind die am Sockelflansch angeformten Laschen jeweils mit einer aus der Ebene des Sockelflansches herausragenden Wölbung versehen. Außerdem bestehen der Sockelflansch und die angeformten Lasche vorteilhafterweise aus einem Metall. Auf diese Weise lassen sich am einfachsten eine Federwirkung senkrecht zur Sockelflanschebene sowie eine hohe Festigkeit und Elastizität erzielen. Da die erfindungsgemäße Lampe durch eine Drehbewegung in die Lampenmontageöffnung des Scheinwerfers eingesetzt wird, erstrecken sich die an den Sockelflansch angeformten Laschen vorteilhafterweise in azimutaler Richtung und besitzen dieselbe Orientierung. Außerdem sind sie vorzugsweise gleichartig ausgebildet.Advantageously, the lugs formed on the base flange are each provided with a protrusion protruding from the plane of the base flange. In addition, the base flange and the molded tab advantageously made of a metal. In this way, the easiest way to achieve a spring action perpendicular to the base flange plane and a high strength and elasticity. Since the lamp according to the invention is inserted by a rotational movement into the lamp mounting opening of the headlamp, the tabs integrally formed on the base flange advantageously extend in the azimuthal direction and have the same orientation. In addition, they are preferably formed similar.

Nachstehend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels näher erläutert.The invention will be explained in more detail below with reference to a preferred embodiment.

Bei dem bevorzugten Ausführungsbeispiel der Erfindung handelt es sich um eine kittlos gesockelte Einfaden-Halogenglühlampe, die für den Einsatz in einen Kraftfahrzeugscheinwerfer vorgesehen ist. Diese Lampe besitzt einen gläsernen, im wesentlichen zylindrischen Lampenkolben 1, der in einem metallischen Lampensockel 2 fixiert ist. Innerhalb des Lampenkolbens 1 ist eine Glühwendel 3 angeordnet, die über zwei Stromzuführungen 4, 5 mit den elektrischen Sockelkontakten 6, 7 verbunden ist. Der Lampensockel 2 besteht im wesentlichen aus einem napfartigen metallischen Fixierring 2a, in dem ein Ende des Lampenkolbens 1 befestigt ist, einem metallischen Justierring 2b, in dem der Fixierring 2a fixiert ist, und einem metallischen Referenzring 2c. Der Lampensockel 2 weist außerdem einen aus einem elektrisch isolierenden Material bestehenden Sockelstein 2d auf, der zur elektrischen Isolierung der beiden Sockelkontakte 6, 7 dient. Der Referenzring 2c ist mit einem im wesentlichen rotationssymmetrischen Sockelflansch 20 ausgestattet. Die Sockelflanschebene ist senkrecht zur Ringachse des Referenzrings 2c und damit auch senkrecht zur Lampenlängsachse ausgerichtet. Außerdem ist der Referenzring 2c mit drei an seiner Oberkante angeformten, radial nach außen gerichteten Referenznasen 21 versehen, die sich in einer gemeinsamen Ebene parallel zur Sockelflanschebene erstrecken. Der Justierring 2b besitzt drei, an seine Unterkante angeformte und radial nach außen abgewinkelte Schweißfahnen, die auf den Referenznasen 21 des Referenzringes 2c aufliegen und mit ihnen 21 verschweißt sind. Der Sockelflansch 20 ist mit drei gleichartigen, äqidistant entlang seines Umfangs verteilten Laschen 22 ausgestattet. Die Laschen 22 erstrecken sich nicht in radialer, sondern in azimutaler Richtung und ihre freien Enden weisen jeweils eine aus der Ebene des Sockelflansches 20 herausragende Wölbung 22a auf. Sie besitzen bezüglich des Sockelflansches 20 und der Ringachse des Referenzringes 2c dieselbe Orientierung, das heißt, der Sockelflansch 20 und die Laschen 22 sind symmetrisch bezüglich 120-Grad-Drehungen um die Ringachse des Referenzringes 2c ausgebildet. Die Laschen 22 sind einteilig mit dem Sockelflansch 20 ausgeführt und bestehen ebenso wie dieser 20 aus einem Metall. Die Laschen 22 üben eine Federwirkung senkrecht zur Ebene des Sockelflansches 20, also in Richtung der Ringachse des Referenzringes 2c bzw. in Richtung der Lampenlängsachse aus.The preferred embodiment of the invention is a cemented single-cap halogen incandescent lamp intended for use in a motor vehicle headlight. This lamp has a glassy, substantially cylindrical lamp bulb 1, which is fixed in a metallic lamp cap 2. Within the lamp bulb 1, an incandescent filament 3 is arranged, which is connected via two power supply lines 4, 5 to the electrical base contacts 6, 7 is. The lamp cap 2 consists essentially of a cup-like metallic fixing ring 2a, in which one end of the lamp bulb 1 is fixed, a metallic Justierring 2b, in which the fixing ring 2a is fixed, and a metallic reference ring 2c. The lamp base 2 also has a base made of an electrically insulating material 2d, which serves for the electrical insulation of the two base contacts 6, 7. The reference ring 2c is equipped with a substantially rotationally symmetrical base flange 20. The base flanges plane is perpendicular to the ring axis of the reference ring 2c and thus aligned perpendicular to the lamp longitudinal axis. In addition, the reference ring 2c is provided with three, at its upper edge formed, radially outwardly directed reference lugs 21 which extend in a common plane parallel to the base flange plane. The adjusting ring 2b has three, integrally formed on its lower edge and radially outwardly angled welding lugs which rest on the reference lugs 21 of the reference ring 2c and are welded to them 21. The base flange 20 is provided with three similar tabs 22 distributed equidistantly along its circumference. The tabs 22 do not extend in the radial, but in the azimuthal direction and their free ends each have a bulge 22a protruding from the plane of the base flange 20. They have the same orientation with respect to the base flange 20 and the ring axis of the reference ring 2c, that is, the base flange 20 and the tabs 22 are formed symmetrically with respect to 120 degree rotations about the ring axis of the reference ring 2c. The tabs 22 are made in one piece with the base flange 20 and consist as well as this 20 of a metal. The tabs 22 exert a spring action perpendicular to the plane of the base flange 20, ie in the direction of the ring axis of the reference ring 2c or in the direction of the lamp longitudinal axis.

Bei der Montage der erfindungsgemäßen Lampe im Fahrzeugscheinwerfer wirken die Referenznasen 21 mit den Laschen 22 zusammen. Die Referenznasen 21 greifen in die Lampenmontageöffnung des Scheinwerfers hinein und liegen an der Innenseite des Scheinwerfers an, während die Laschen 22 an der Außenseite des Scheinwerfers anliegen. Nach dem Einsetzen der Lampe in die Lampenmontageöffnung des Scheinwerfers wird die Lampe durch eine Vierteldrehung um ihre Längsachse in ihrer endgültigen Lage fixiert. Der Rand der Lampenmontageöffnung ist klemmend zwischen den Referenznasen 21 und den Laschen 22 angeordnet. Die Referenznasen 21 sind wie in der Patentanmeldung WO 97/25733 beschrieben ausgebildet. Außerdem besitzt die Lampe wie ebenfalls in der vorgenannten Patentanmeldung offenbart eine Andruckfeder, die eine Federwirkung senkrecht zur Längsachse der Lampe ausübt und dadurch eine seitliche Fixierung der Lampe in der Lampenmontageöffnung des Scheinwerfers gewährleistet.When mounting the lamp according to the invention in the vehicle headlight, the reference lugs 21 cooperate with the tabs 22. The reference lugs 21 engage in the lamp mounting opening of the headlight and lie on the inside of the headlamp, while the tabs 22 abut the outside of the headlamp. After inserting the lamp in the lamp mounting hole of the headlamp, the lamp is rotated by a quarter turn about its longitudinal axis fixed in their final position. The edge of the lamp mounting opening is arranged by clamping between the reference lugs 21 and the tabs 22. The reference noses 21 are designed as described in the patent application WO 97/25733. In addition, as likewise disclosed in the aforementioned patent application, the lamp has a pressure spring which exerts a spring action perpendicular to the longitudinal axis of the lamp and thereby ensures lateral fixing of the lamp in the lamp mounting opening of the headlight.
