Publication number: 20130155707Abstract: An improved incandescent light source as may be used in a vehicle headlamp for providing forward illumination. The illuminating system includes a filament coil and an anisotropic reflector assembly. The filament coil is constructed from a coil of wire that is electrically conductive and has a high melting point and the primary axis of the coil of wire is substantially aligned with a principal axis of the reflector system. The light flux emitted by the filament coil toward the reflector system is rotationally anisotropic.Type: ApplicationFiled: December 15, 2011Publication date: June 20, 2013Inventors: Istvan MUDRA, Laszlo Nagy, Jozsef Gallai

Publication number: 20130051059Abstract: An optically adjustable light module, such as a daytime running lamp of a motor vehicle, includes a housing. At least one light source is rotatable about a rotational axis and has an optical axis, the light source being disposed in an interior of the housing. A direction adjuster is disposed at an exterior of the housing. The housing is sealed against moisture. Movement of the direction adjuster rotates the light source about the rotational axis and adjusts a position of the optical axis.Type: ApplicationFiled: April 20, 2012Publication date: February 28, 2013Applicant: GENERAL ELECTRIC COMPANYInventors: Robert Abai, Zoltan Bako, Istvan Mudra, Jozsef Gallai, Imre Molnar, Peter Pinter

Patent number: 7413600Abstract: A composition for the manufacture of an opaque silvery coating on a glass surface is provided. The composition comprises a mixture of at least two metal powders. The metal powder mixture contains carbonyl iron and aluminum, and a carrier liquid for forming a suspension of the metal powder mixture. A method for manufacturing an opaque silvery coating for a lamp having a glass envelope is also provided. In the method, a suspension comprising a mixture of carbonyl iron and aluminum powders in a carrier liquid is applied onto the envelope of the lamp. The suspension is dried, and thereafter the composition remaining from the suspension is burned at a temperature above 500° C. A lamp with a glass envelope and a single layer opaque coating covering at least a part of the glass envelope is also disclosed. The opaque coating comprises 50 to 80 weight % carbonyl iron and 20 to 50 weight % elementary aluminum.Type: GrantFiled: February 15, 2007Date of Patent: August 19, 2008Assignee: General Electric CompanyInventors: István Mudra, Péter Szemere

Patent number: 7002285Abstract: A discharge lamp is disclosed, which comprises a discharge vessel sealed in a tubular envelope. The lamp has a lamp base covering an end part of the envelope, and fixing means for providing a substantially rigid fixing of the envelope to the lamp base. The fixing means comprises a metal clamp ring, which surrounds a part of the envelope external to the lamp base. A melt plastic lining is provided between the clamp ring and the envelope. The melt plastic lining substantially completely fills a space between the envelope and the clamp ring. A method is also provided for manufacturing a discharge lamp as above. The method comprises the steps of providing a space between the clamp ring and the envelope, and providing a hot-melt plastic lining in the space between the clamp ring and the envelope.Type: GrantFiled: January 3, 2003Date of Patent: February 21, 2006Assignee: General Electric CompanyInventors: István Mudra, Szabolcs Bella, Pál Garamvölgyi
