Abstract

Eine Kfz-Scheinwerfer-Einheit enthält einen Reflektor (1), in dem eine zweiseitig gequetschte Entladungs­ lampe (2) axial angeordnet ist. Die der Lichtaus­ trittsöffnung zugewandte vordere Quetschung (12) der Lampe ist in einer zylindrischen Tülle (13) geführt, die über eine Haltevorrichtung (14) starr mit dem Reflektor (1) verbunden ist. Eine Hülse an der vorderen Quetschung (12) erleichtert das Einfädeln in die zylindrische Tülle (13). Die Anordnung gewährt einen verbesserten Vibrationsschutz. Außerdem wird die Hochspannungsisolation dadurch verbessert, daß die elektrische Zuleitung zu der aus der vorderen Quetschung (12) austretenden Stromzuführung über einen Kabelkanal (17) an der Haltevorrichtung (14) erfolgt. A motor vehicle headlight unit contains a reflector (1) in which a bilaterally squeezed discharge lamp (2) is arranged axially. That of the lights front pinch facing front pinch (12) Lamp is guided in a cylindrical spout (13), the rigid with a holding device (14) Reflector (1) is connected. A sleeve on the front pinch (12) facilitates threading into the cylindrical spout (13). The order granted improved vibration protection. In addition, the High voltage insulation improved in that the electrical lead to that from the front Squeeze (12) emerging power supply via a Cable duct (17) on the holding device (14).
