Patent number: 9980347Abstract: The invention relates to a lighting system for lighting a space (R) which lighting system has means (4) for producing space illumination over a large area, and means (5) for producing concentrated local lighting. Furthermore the lighting system has a presence detector (6) for detecting the presence of at least one person (P) in the space (R) and a control device (8) for controlling the means (4) for producing the space illumination and the means (5) for producing the local lighting. To this end the control device (8) is configured to control the space illumination over a large area automatically as a function of the daylight or as a function of the daytime and to control the local lighting automatically as a function of the presence of at least one person (P) in the space (R). Because the space illumination is controlled automatically as a function of the daylight or of the daytime, the illumination can be prevented from being reduced so much that a lighting mood is produced which has a negative effect.Type: GrantFiled: March 26, 2015Date of Patent: May 22, 2018Assignee: ZUMTOBEL LIGHTING GMBHInventors: Manfred Petschulat, Sebastian Schubnell

Patent number: 8410722Abstract: In an illumination system (1) having a control unit (2) and at least one de-central lamp operating device (12, 22) for operating one or more associated lamps (LA), the lamp operating device (12, 22) can be operated in different operational modes. In accordance with the invention the central control unit (2) and the lamp operating device (12, 22) are so configured that the selection and setting of an operational mode for the lamp operating device (12, 22) can be carried out from or via the central control unit (2).Type: GrantFiled: March 23, 2005Date of Patent: April 2, 2013Assignee: Zumtobel Lighting GmbHInventors: Günter Johler, Manfred Petschulat, Thomas Roth

Patent number: 8317354Abstract: The invention relates to a lamp (1), especially a suspended lamp, comprising a housing (2) that is provided with a first light emitting area (4) with a first light influencing element (9) on one side thereof while being fitted with a second light emitting area (21) with a second light influencing element (22) on another side for direct illumination. In order to improve indirect illumination of the lamp, the second light influencing element (22) can be moved into at least two different positions (S1, S2, S3).Type: GrantFiled: April 18, 2007Date of Patent: November 27, 2012Assignee: Zumtobel Lighting GmbHInventors: Patrick Gassner, Manfred Petschulat, Hartmut S. Engel

Patent number: 8231259Abstract: The present invention relates to a luminaire, which comprises a plate-shaped light guide, and first lamps disposed on one or more narrow sides of the light guide and configured to couple light into the plate-shaped light guide, wherein the light coupled into the light guide is emitted via a flat side of the light guide in a first irradiating direction of the luminaire. Said luminaire is characterized in that the first lamps are formed by a plurality of light-emitting diodes and that the luminaire furthermore comprises second lamps and a reflector arrangement associated therewith, by way of which the light of the second lamps is emitted in a second irradiating direction opposite the first irradiation direction.Type: GrantFiled: March 13, 2009Date of Patent: July 31, 2012Assignee: Zumtobel Lighting GmbHInventors: Katherina Keller, Manfred Petschulat

Patent number: 8201978Abstract: A luminaire having a box-like luminaire housing for receiving at least one elongate light source and at least one reflector surface arranged—seen from the region to be illuminated—neighboring the light source, the luminaire housing forms a light exit opening which is closed by a light exit element. The light exit element has in a first emission region, located in substance in front of the light source, a first light emission characteristic, and has in a second emission region, separate from the first emission region, a second light emission characteristic different with respect to the first light emission characteristic.Type: GrantFiled: January 31, 2007Date of Patent: June 19, 2012Assignee: Zumtobel Lighting GmbHInventors: Gerald Ladstätter, Patrik Gassner, Manfred Petschulat
