Publication number: 20100148668Abstract: 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.Type: ApplicationFiled: November 26, 2009Publication date: June 17, 2010Applicant: OSRAM GESELLSCHAFT MIT BESCHRAENKTER HAFTUNGInventors: Matthias Damm, Andreas Nittke

Patent number: 7402952Abstract: 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.Type: GrantFiled: November 19, 2004Date of Patent: July 22, 2008Assignee: Patent-Treuhand-Gesellschaft für elektrische Glühlampen mbHInventors: Axel Bunk, Matthias Damm, Georg Rosenbauer, Joachim Werner

Patent number: 7397192Abstract: 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.Type: GrantFiled: July 5, 2005Date of Patent: July 8, 2008Assignee: Patent-Treuhand-Gesellschaft für elektrische Glühlampen mbHInventors: Matthias Damm, Christoph Krieglmeyer, Roland Stark

Publication number: 20080036382Abstract: 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).Type: ApplicationFiled: July 11, 2005Publication date: February 14, 2008Inventors: Gerhard Wolf, Frank Friess, Georg Schwarz, Adalbert Kovacs, Axel Bunk, Georg Rosenbauer, Matthias Damm
