Abstract

Die Erfindung betrifft eine elektrische Lampe mit mindestens einer Molybdänfolienabdichtung eines Lampengefäßes (30, 40) und mindestens einem geschlitzten Metallstift (35, 44), wobei der mindestens eine geschlitzte Metallstift (35, 44) mit einer Molybdänfolie (32, 42) der mindestens einen Molybdänfolienabdichtung elektrisch leitend verbunden ist, dadurch gekennzeichnet, dass ein Ende (321) der Molybdänfolie (32, 42) in dem Schlitz (350) des mindestens einen geschlitzten Metallstifts (35, 44) angeordnet und fixiert ist. Der Metallstift (35, 44) ist vorzugsweise als Stromzuführungsdraht oder Gasentladungselektrode ausgebildet.
