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.
Claims8
An electric lamp having a longitudinal axis, wherein the electric lamp is provided with a pinch seal;
- said pinch seal having two narrow sides and two broad sides, and wherein the electric lamp has a bulb consisting of quartz glass equipped with said pinch seal and films fitted therein, in which bulb a light-emitting element is held at the ends of said light-emitting element by a frame, wherein the frame has at least one wire clip, which holds an end of the light-emitting element which is remote from the films, wherein the wire clip is manufactured at least partially from tungsten and is bent back at an angle at a film-side end of said wire clip, and wherein a film associated with the wire clip is folded in the form of a V along the longitudinal axis, and a film associated with the light-emitting element is planar.
