Patent number: 7446463Abstract: The invention relates to contact-making of dielectrically impeded discharge lamps by means of a mechanical procedure with plastic deformation of a contact surface 17. It is thus possible to dispense with thermal steps such as soldered connections or welded connections and to therefore make savings in terms of time and on the complexity of the apparatus used.Type: GrantFiled: July 21, 2005Date of Patent: November 4, 2008Assignee: Patent-Treuhand-Gesellschaft fuer Elektrische Gluehlampen mbHInventors: Gerhard Döll, Jörg Otterstätter

Patent number: 7025472Abstract: A coupling element (2) is proposed for the combining of at least two elongate lamps with in each case two ends. For this purpose, the coupling element (2) has a continuous receptacle area which is provided for receiving an end of each lamp. The receptacle area comprises a reflector (6) in order to reduce the luminance decrease in the region between the lamp ends. With one or a plurality of coupling elements according to the invention in conjunction with two or more elongate lamps, illumination systems having different luminous lengths can be realized in a modular manner.Type: GrantFiled: March 23, 2004Date of Patent: April 11, 2006Assignee: Patent-Treuhand-Gesellschaft für elektrische Gluehlampen mbHInventors: Gerhard Döll, Jörg Rink

Patent number: 6984930Abstract: A dielectric barrier discharge lamp having electrodes arranged on the wall of the discharge vessel has a VUV/VIS reflection layer (6) made of a material with a high secondary electron emission coefficient on at least a part of the inner wall of the discharge vessel. A luminescent material layer (7) is in turn applied on the VUV/VIS reflection layer (6). Moreover, at least one partial region (8) without luminescent material is provided in the luminescent material layer (7), this at least one partial region (8) partially uncovering the underlying VUV/VIS reflection layer (6) and additionally being arranged at least in direct proximity to one or more electrodes (4) of the lamp. As a result, the ignition behavior of the lamp is improved, in particular during ignition in darkness.Type: GrantFiled: July 4, 2002Date of Patent: January 10, 2006Assignee: Patent-Treuhand-Gesellschaft fuer Elektrische Gluehlampen mbHInventor: Gerhard Döll

Patent number: 6960874Abstract: A dielectric barrier discharge lamp (1) having a tubular discharge vessel (2) and a luminescent material layer on at least a part of the inner wall of the discharge vessel (2) and having elongate electrodes (3) is provided with a coating (10) on a partial region of the inner wall at least at one end of the tubular discharge vessel (2), which coating additionally covers an end of at least one elongate electrode (3) . The material of the coating (10) has a high secondary electron emission coefficient. As a result, the ignition behavior of the lamp is improved, in particular during ignition in darkness.Type: GrantFiled: July 9, 2002Date of Patent: November 1, 2005Assignee: Patent-Treuhand-Gesellschaft fuer Elektrische Gluehlampen mbHInventor: Gerhard Döll

Patent number: 6777878Abstract: A dielectric barrier discharge lamp has elongated electrodes (3) that are arranged on the inside of the wall of the discharge vessel (2) and are covered by a dielectric layer (4). Arranged on the outside of the wall of the discharge vessel (2) is an electrically conductive means (8) that is limited with reference to the longitudinal axis to a subregion (B) of the discharge vessel wall, for example a metal ring. The startability of the dielectric barrier discharge lamp when first being started or after long operational pauses is improved thereby.Type: GrantFiled: July 2, 2002Date of Patent: August 17, 2004Assignee: Patent-Treuhand-Gesellschaft fuer Elektrische Gluehlampen mbHInventors: Werner Berlinghof, Gerhard Döll, Wolfgang Kumpf, Gerwin Thiel

Patent number: 6259214Abstract: An operating method, in particular a dimming method for a discharge lamp. In order to set the maximum brightness, two outer electrodes (5,6), for example, are used to generate in the discharge lamp a dielectrically impeded discharge which, through the formation of xenon excimers, emits UV radiation which is converted into light with the aid of fluorescent materials (2). In order to permit intense dimming of the discharge lamp, two cold cathodes (3, 4) are used to generate a xenon low-pressure discharge emitting UV beams, and the dielectrically impeded discharge is switched off. Both types of discharge are preferably excited by high-voltage pulses which are generated by an operating unit (7). Dimming is preferably performed by blanking pulse trains.Type: GrantFiled: June 14, 2000Date of Patent: July 10, 2001Assignee: Patent-Treuhand-Gesellschaft fuer elektrische Gluehlampen mbHInventors: Gerhard Doell, Hartwig Riehl, Martin Enders
