  • Publication number: 20100148668
    Abstract: A halogen incandescent lamp is provided in various embodiments. The halogen incandescent lamp may include a bulb in which there are accommodated a luminous element and a fill with a halogen-containing additive; the halogen being at least one of iodine and bromine, wherein there is accommodated in the interior of the bulb a layer which can be activated at suitable temperatures, the layer containing at least one of bromine, chlorine, fluorine and oxides or sulfides and is arranged such that it can be touched by the luminous element in the case when the latter is passed through and, during operation of the lamp, ensures the lamp is quickly switched off owing to the release of a reactive substance.

  • Patent number: 7402952
    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.

  • Patent number: 7397192
    Abstract: Disclosed is a halogen incandescent lamp having a lamp vessel, which is sealed at one end and in which at least one luminous element is accommodated, a vessel section 42 being in the form of a side reflector which extends only over a subregion of the lamp vessel circumference. A light-exit window 40 adjoins this vessel section 42 in the circumferential direction. According to the invention, the light-exit window 40 is comparatively slightly curved in cross section, the vessel section 42 forming the side reflector bulging out away from the light-exit window 40. This bulged-out region is preferably provided with a kidney-shaped constriction 46.

  • Publication number: 20080036377
    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.

  • Publication number: 20080036382
    Abstract: A light source comprising a heatable filament (1) or an electrode, wherein the filament (1) or the electrode is arranged in a lamp (2) or in a tube. In order to use the light source in a wide variety of manners even in rough conditions, the filament (1) or the electrode is provided at least partially with a mechanical stabilization system. The invention also relates to a method for mechanical stabilization of the filament (1) or electrode of a light source, wherein stabilization is produced by exposing the filament (1) or electrode to a short pulsed gas pressure increase, involving a rare gas, during heating. Stabilization may also be produced by a coating or deposition (4).
