Abstract
In various embodiments, a lamp has a bulb with a pinch seal, which holds a light-emitting element by means of a wire clip. The wire clip consists of tungsten and has, at an end remote from films embedded in the pinch seal, an eyelet for holding the light-emitting element. An end of the wire clip which is close to a film is bent back. A film associated with the wire clip is folded in a roof-shaped manner. Overall, it is thus possible to realize a lamp with a long life.
