Abstract (en)
[origin: WO2006007815A1] The invention relates to a light bulb (1) comprising an illumination body (7), which is inserted, together with a filler material, into a bulb (2) in a vacuum-tight manner. The illumination body (7) has a metal carbide, whose melting point lies above that of tungsten. The current supply (10) is configured in two parts from a first section (6) and a second section (15). The first section is configured integrally with the illumination body (7) and consists of a wire and the second section, which functions as the actual current supply (15) is produced from a highly heat-resistant material.
