Abstract

Die Erfindung betrifft eine Hochdruckentladungslampe, insbesondere eine Kraftfahrzeugscheinwerferlampe, mit mindestens einem Lampengefäß (100), das ein erstes, in einem Lampensockel angeordnetes Ende (101) und ein zweites, sockelfemes Ende (102) besitzt. Erfindungsgemäß ist zumindest die von dem Lampensockel (110) abgewandte Stirnseite des sockelfernen Endes (102) mit einer für Licht und UV-Strahlung undurchlässigen Abdeckung (125) versehen ist.
