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. The invention relates to a high - pressure discharge lamp, in particular a motor vehicle headlamp, having at least one lamp vessel (100) which has a first end (101) arranged in a lamp base and a second, base end (102). According to the invention, at least the end face remote from the lamp cap (110) of the socket-distal end (102) is provided with a cover (125) which is impermeable to light and UV radiation.
