Abstract

The invention relates to an electric lamp with a longer service life, comprising a quartz-glass envelope having at least one sealed end, containing at least one current feedthrough comprising a thin molybdenum foil entirely embedded within said sealed end, a first conductor connected to said molybdenum foil by an overlapping connection and extending interiorly of said envelope, and a second conductor connected to said molybdenum foil and extending exteriorly of said envelope, wherein the overlapping connection is a weld, which has a length which is between 0.01 and 1.5 times the diameter of the first conductor, and the foil is in a plane, of which the distance to a centre line through the first conductor is less than 0.9 times, preferably less than 0.5 times, the radius of the first conductor.
