Patent number: 7385211Abstract: A method of generating extreme ultraviolet radiation, wherein the radiant medium is a plasma generated by processing a basic material, and the basic material distribution of the radiant medium consists at least of one halogenide of the metals lithium (Li), indium (In), tin (Sn), antimony (Sb), tellurium (Te), aluminum (Al) and/or a halogen 5 and/or an inert gas, with the exception of halogenides on the basis of lithium (Li) and chlorine (Cl) as well as fluorine (F).Type: GrantFiled: April 22, 2003Date of Patent: June 10, 2008Assignee: Koninklijke Philips Electronics, N.V.Inventors: Guenther Hans Derra, Ulrich Niemann

Publication number: 20060273728Abstract: A high-pressure gas discharge (HID, high intensity discharge) lamp is described, having a discharge vessel (1) that contains a metal that is applied at least to parts of those regions of the feedthroughs and/or walls of the discharge vessel (1) at which condensation of ingredients of the gas filling may occur as a result of a temperature sink that occurs when the lamp is in a state of operation. In this way, it is possible to at least largely prevent not only chemical interactions between ingredients of the gas filling (particularly the metal halides) and the relevant regions of the feedthroughs or walls at which, due to the lower temperature of these regions, the ingredients condense, but also losses of ingredients of this kind from the gas filling. This in turn means that there is no risk of any damage to the lamp or of any degradation of its lumen maintenance.Type: ApplicationFiled: September 1, 2004Publication date: December 7, 2006Applicant: Koninklijke Philips Electrnics N.V.Inventors: Matthias Born, Ulrich Niemann

Patent number: 5113119Abstract: An electrodeless high pressure discharge lamp contains a halide or oxyhalide of W, Ta, Re, or rhenium oxide in such a quantity that a supersaturated metal vapor arises in the discharge, by which metal particles are formed. Owing to their high temperature these particles generate thermal emission. The lamp has a high color temperature and a high color rendering index.Type: GrantFiled: August 29, 1990Date of Patent: May 12, 1992Assignee: U.S. Philips CorporationInventors: Ulrich Niemann, Stephan Offermanns, Bernhard Weber
