Die Lampenfassung weist ein Gehäuse auf, in dem die Lampe vormontierbar ist und das am Reflektor mittels einer Verriegelungseinrichtung befestigbar ist. Im Gehäuse ist ein Federelement angeordnet, durch das Druck auf die Lampe zum Reflektor hin ausgeübt wird, so daß diese mit ihrem Sockelteller am Reflektor anliegt. Die Lampe weist eine aus deren Sockel ragende elektrisches Kontaktfahne auf, durch die der plusseitige Anschluß der Lampe erfolgt. Der masseseitige Anschluß der Lampe erfolgt über deren metallischen Sockelteller. Das Gehäuse der Lampenfassung ist durchgehend offen ausgebildet, so daß keine Abdichtung vorhanden ist und Feuchtigkeit und Schmutz in die Lampenfassung und den Reflektor eindringen kann. Durch das offene Gehäuse hindurch kann mit der Kontakfahne der Lampe ein Steckerteil zusammengefügt werden, über das der plusseitige Anschluß der Lampe erfolgt. Zum masseseitigen Anschluß der Lampe weist der Reflektor einen metallischen Kragen auf, an dem der Sockelteller der Lampe zur Anlage kommt und an dem ein Kabelschuh angeklemmt ist. Die elektrischen Anschlüsse der Lampe sind somit aufwendig herzustellen.DE 41 39 618 A1 is a lamp holder for Motor vehicle headlights known with a lamp on a reflector of the headlight can be attached. The Lamp holder has a housing in which the lamp is pre-assembled and that on the reflector by means of a Locking device can be attached. There is a in the housing Spring element arranged by the pressure on the lamp Reflector is exercised so that this with her Base plate rests on the reflector.

Bei der bekannten Lampenfassung ist die Lampe über die (zweiteilige) Lampenfassung lediglich mittelbar an dem Reflektor befestigt. Bei der Herstellung der Lampenfassung können Fertigungstoleranzen dazu führen, dass bei an dem Reflektor befestigter Lampenfassung und in der Lampenfassung angeordneter Lampe die Lampe nicht immer genau in der gewünschten Lage relativ zu dem Reflektor angeordnet ist. Dadurch können sich von Scheinwerfer zu Scheinwerfer unterschiedliche Lichtverteilungen ergeben, was aus Gründen der Verkehrssicherheit unerwünscht ist.In the known lamp holder, the lamp is over the (two-part) lamp holder only indirectly attached to the reflector. In the manufacture of the lamp holder Manufacturing tolerances can lead to the fact that when attached to the reflector Lamp holder and lamp arranged in the lamp holder, the lamp does not is always arranged exactly in the desired position relative to the reflector. This can vary from headlamp to headlamp Light distributions result in what is undesirable for reasons of traffic safety.

Ein weiterer Nachteil der bekannten Lampenfassung besteht darin, dass diese dank der Rastmittel zwar relativ einfach in einer entsprechenden Einbauöffnung des Reflektors zu befestigen ist; allerdings gestaltet sich das Auswechseln der Lampe, wozu die Lampenfassung aus dem Reflektor entnommen werden muss, äußerst kompliziert und aufwendig, da die Rastverbindung nur sehr schwer lösbar ist.Another disadvantage of the known lamp holder is that it thanks the latching means is relatively simple in a corresponding installation opening of the To fix the reflector; however, the lamp is replaced, what the lamp holder must be removed from the reflector, extremely complicated and expensive, since the snap connection is very difficult to solve.
