Abstract

Zumindest bei einem Ende der Metallhalogenidlampe mit keramischem Entladungsgefäß (25) ist die Durchführung ein Cermet-Bauteil (9) (Stift oder Kapillarrohr), dessen Metallgehalt so hoch ist, daß es wie ein Metall verschweißbar ist. Die Befestigung der Durchführung (9) und des Stopfens (26) erfolgt ohne Glaslot durch Direkteinsinterung.

Figure 00000001
At least at one end of the metal halide lamp with ceramic discharge vessel (25), the feedthrough is a cermet component (9) (pin or capillary tube), the metal content of which is so high that it can be welded like a metal. The bushing (9) and the plug (26) are attached without glass solder by direct sintering.
