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: 7291979Abstract: In the dielectric barrier discharge lamps according to the invention, the elongate, for example strip-like or linear, electrodes are each separated into two electrode elements (14a, 14b; 15a, 15b) by a gap in the longitudinal direction. This makes it possible, as intended, to operate one element (14a, 15a) of the electrode elements separately from the other element (14b, 15b) and, as a result, to cause either only one part of the lamp to illuminate or the entire lamp. For this purpose, one element (14a, 15a) of the electrode elements is connected to a first operating device (22), and the other element (14b, 15b) to a second operating device (21).Type: GrantFiled: February 8, 2005Date of Patent: November 6, 2007Assignee: Patent-Treuhand-Gesellschaft fuer Elektrische Gluehlampen mbHInventor: Gerhard Doll

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

Publication number: 20050236997Abstract: In the case of a dielectric barrier discharge lamp, the discharge vessel (1) is composed of an outer bulb (3) and an inner bulb (4) arranged within the outer bulb, with the result that a discharge space (8) filled with a discharge medium is formed between the inner and the outer bulb. Strip-like electrodes (11) are arranged on the outer side, which is remote from the discharge medium, of the wall of the inner bulb (4). Since there are no longer inner electrodes having a dielectric coating and there is no gas-tight current bushing, this concept combines simple manufacture with protection of the outer electrodes, for example against electric shock.Type: ApplicationFiled: April 20, 2005Publication date: October 27, 2005Applicant: PATENT-TREUHAND-GESELLSCHAFT FUR ELEKTRISCHE GLUHLAMPEN MBHInventors: Walter Danner, Gerhard Doll
