Abstract

The invention relates to a light source, in particular, an incandescent lamp, which comprises a tube (2) and a filament (1) which can be heated and is arranged in the tube (2). The light source is embodied in such a manner that the operating life thereof and of the filament (1) is extended. As a result the filament (1 ) consists at least partially of monocrystalline filament material. The invention also relates to a filament (1) for the above-mentioned light source. The invention further relates to a method for producing a monocrystalline metal wire, in particular a filament (1) for a light source and a metal raw wire which is used as an initial material. According to said method, the raw wire is subjected, at least sectionally, to zone crystallisation which leads to the formation of an essentially monocrystalline metal structure.
