Description

Die Erfindung betrifft eine Lampenaufnahme für Scheinwerfer, insbesondere eines Fahrzeugs, mit einem eine radiale Aufnahmefläche aufweisenden Ringelement zur Anlage eines Sockels der Lampe und mit einem rohrförmigen Fassungskörper aus einem elektrisch leitenden Material, der sich in der Montageposition der Lampe zwischen einem elektrisch leitenden Abschnitt eines Reflektors und einem elektrisch leitenden Gehäuse eines Zündgerätes für die Lampe erstreckt, wobei dem rohrförmige Fassungskörper Befestigungsmittel zur Arretierung der Lampe in der Montageposition zugeordnet sind.The invention relates to a lamp holder for headlights, in particular a vehicle, having a radial receiving surface having a ring member for supporting a base of the lamp and a tubular socket body of an electrically conductive material extending in the mounting position of the lamp between an electrically conductive portion of a reflector and an electrically conductive housing of an ignitor for the lamp extends, wherein the tubular socket body fastening means for locking the lamp are assigned in the mounting position.

Dem rohrförmigen Fassungskörper sind Befestigungsmittel zugeordnet zur Arretierung der Lampe in der Montageposition. Darüber hinaus umfasst die Lampenaufnahme ein Ringelement, das eine radiale Aufnahmefläche aufweist zur Aufnahme eines Sockels der Lampe. Um die Abstrahlung eines elektromagnetischen Feldes zu verhindern, ist an dem rohrförmigen Fassungskörper eine axial verlaufende Kralle befestigt, die in der Montageposition ein elektrisch leitendes Gehäuse des Zündgerätes kontaktiert. Auf diese Weise ist eine durchgehende elektrisch leitende Fläche zwischen dem Reflektor und dem Zündgerät gewährleistet. Nachteilig an der bekannten Lampenaufnahme ist, dass zu Abschirmzwecken zusätzliche elektrisch leitende Krallenelemente an dem rohrförmigen Fassungskörper befestigt werden müssen.From the EP 1 801 494 B1 For example, there is known a lamp holder for headlamp comprising a tubular socket body made of an electrically conductive material extending in a region between a reflector and a lamp ignitor.

In addition, the lamp holder comprises a ring element, which has a radial receiving surface for receiving a base of the lamp. In order to prevent the emission of an electromagnetic field, an axially extending claw is attached to the tubular socket body, which contacts an electrically conductive housing of the ignition device in the mounting position. In this way, a continuous electrically conductive surface between the reflector and the igniter is ensured. A disadvantage of the known lamp holder is that for shielding purposes additional electrically conductive claw elements must be attached to the tubular socket body.
