Abstract:
The invention relates to an incandescent lamp having a carbide-containing luminous element and current supplies holding the luminous element. A luminous element is introduced into a bulb together with a filling in a vacuum-tight manner, said luminous element having a metal carbide the melting point of which is preferably above that of tungsten, and the luminous element being helical. The rise of the filament varies from the center towards the ends.
