Abstract (en)
[origin: US2008012488A1] The invention relates to a light bulb comprising an illumination body, which is inserted, together with a filler material, into a bulb in a vacuum-tight manner. The illumination body has a metal carbide, whose melting point lies above that of tungsten. The current supply is configured in two parts from a first section and a second section. The current supply is configured integrally with the illumination body from a single wire and is covered with a coating that reduces the susceptibility to breakage.
