Abstract: 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.

Abstract: An incandescent lamp having a carbide containing luminous element, uses a wire for the luminous element that is coated on the outside with at least two different high melting metal compounds from at least one of the groups of carbides, borides and nitrides. The luminous element reaches a temperature of at least 3000° K during operation.

Abstract: 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.

Abstract: The incandescent lamp is equipped with a luminous element which is hermetically inserted in a bulb together with a filling, the luminous element having a metal carbide whose melting point is above that of tungsten. The supply lead is fabricated integrally with the luminous element from a wire and provided with an electrically conducting coating which decisively improves the impact strength and make-proofness.

Abstract: The incandescent lamp, which uses a carbon cycle process, is equipped with a luminous body which, together with a fill, is introduced in a vacuum-tight manner into a bulb, the luminous body including a metal carbide, the melting point of which is above that of tungsten. The distance between the luminous body and the wall of the bulb is less than 18 mm, with a first cycle process, which is attributed to the carbon, being effected by the use of carbon and hydrogen as fill additive, and a second cycle process, which is attributed to the metal, being effected by the use of halogen.

Abstract: The invention relates to a reflector lamp and to a method for producing such a reflector lamp, especially a simplified method for fixing the lamp (2) in the reflector (1). The gasket (22) of the lamp base (21) is disposed in the cavity (13) of the reflector neck (12) in such a manner that the at least one power lead (71, 72) projects from the reflector neck (12) through a passage and the lamp base (21) is supported on the inner wall (13) of the reflector (1) perpendicular to the longitudinal axis (A). A fastening element (81, 82) is fastened on the power lead (71, 72) at an angle to the longitudinal axis (A) and rests against the outer wall of the reflector neck (12). The lamp (2) is thus fixated in the reflector (1) in the longitudinal direction (A) without play and without any additional spring elements.

Abstract: A method and apparatus for producing a lamp in the case of which a lamp bulb closed at one end is filled through a feed opening for a luminous means are disclosed together with a lamp produced using this method. A dome of the lamp bulb can thereby be of smooth design without a pumping tip.
