Patent number: 7488085Abstract: A compact fluorescent luminaire mountable on a vertical surface is provided, the luminaire including a housing, an aperture formed at an underside of the housing, a lamp disposed within the aperture and oriented to emit light through the aperture to the vertical surface, wherein the lamp comprises first and second tube elements arranged adjacent to one another, the first tube element being proximate to the vertical surface, the second tube element being distal from the vertical surface, a shield element disposed within the aperture adjacent to the lamp and extending longitudinally therewith, where the shield element is configured to intercept first light rays emitted by the first tube element, intercept second light rays emitted by the second tube element, and allow passage of third light rays emitted from the first and second tube elements incident on the vertical surface.Type: GrantFiled: April 17, 2006Date of Patent: February 10, 2009Assignee: Sylvan R. Shemitz Designs, Inc.Inventor: David Pfund
-
Patent number: 7377668Abstract: An accent light is provided that easily mounts directly to a linear luminaire across its light-emitting opening and in front of the luminaire's lamp(s). The accent light has one or more mounting devices that easily engage the luminaire. The accent light can be advantageously installed without disrupting a continuous row of linear luminaires.Type: GrantFiled: March 5, 2003Date of Patent: May 27, 2008Assignee: Sylvan R. Shemitz Designs, Inc.Inventors: Sylvan R. Shemitz, Paul R. Ford, Long Dam Quang
-
Patent number: 7360929Abstract: A luminaire including a housing and a multi-purpose mounting feature formed at an interior of the housing, where the mounting feature is configured to receive and retain a mount for mounting of the luminaire on a vertical surface, and where the mounting feature is configured to receive and retain an electrical cord, to direct the electrical cord at least partially along a length of the luminaire, and to conceal the electrical cord from view.Type: GrantFiled: April 11, 2006Date of Patent: April 22, 2008Assignee: Sylvan R. Shemitz Designs, Inc.Inventors: David Pfund, James A. Melling

Patent number: 7347587Abstract: Disclosed is an apparatus for reducing socket shadow in an area of low luminance, the apparatus comprising a luminaire casing, at least two linearly adjacent tandem lamps disposed in the luminaire casing, the at least two lamps each capable of emitting a light output, a region of diminished radiant exitance disposed between adjacent ends of the at least two linearly adjacent lamps, the region of diminished radiant exitance emitting a lower light output than the light output emitted from the at least two lamps and creating the area of low luminance, and a reflector disposed with the luminaire casing, the reflector being disposed proximate the at least two lamps and positioned with respect to the at least two lamps to redirect the light output emitted from the at least two lamps to the area of low luminance.Type: GrantFiled: November 6, 2006Date of Patent: March 25, 2008Assignee: Sylvan R. Shemitz Designs, Inc.Inventors: David Pfund, James A. Melling

Patent number: 7246924Abstract: Lighting louvers formed by transverse and longitudinal blades improve the performance of indirect ambient light luminaires by increasing light output, widening the output of the luminaire's maximum intensity light, or both. These lighting louvers include at least one of the following features: non-symmetrically shaped apertures, wider apertures over (or under) the luminaire's lamp(s), longitudinal blades of shorter height nearest the lamps, and longitudinal blades having differently curved longitudinal sides. Each of these features contributes to improved luminaire performance.Type: GrantFiled: November 22, 2004Date of Patent: July 24, 2007Assignee: Sylvan R. Shemitz Designs, Inc.Inventor: David R Pfund

Patent number: 7097328Abstract: A heat sink for use with luminaires can be tightened securely against a lamp socket and can be loosened to allow the lamp socket to be rotated. The heat sink also contacts preferably an endplate or other structure of the luminaire having a preferably large amount of exterior surface area. Heat is drawn away from the lamp socket and interior of the luminaire via the heat sink to the endplate or other structure, where the heat is dissipated via convection into the surrounding air. By using another structure of the luminaire having a relatively large amount of surface area, the heat sink advantageously need not be large or bulky.Type: GrantFiled: November 24, 2003Date of Patent: August 29, 2006Assignee: Sylvan R. Shemitz Designs, Inc.Inventors: Sylvan R. Shemitz, Paul R. Ford, Gregory L. Moler, Paul C. Johnson

Patent number: 6860618Abstract: Linear luminaires that asymmetrically distribute emitted and reflected light are presented. These luminaires have single or twin unit fluorescent lighting and optional uplighting. Each includes an elliptical baffle assembly and at least one independently adjustable reflector enclosed within the housing of the luminaire. The adjustable reflector is adjustable through at least about 15° of rotation and is at least partially hidden from view by the housing and baffle assembly. The luminaires can be surface mounted, suspended, or cantilever mounted, and include wireways to permit wiring to be run discreetly inside and through adjacent asymmetric distribution luminaires.Type: GrantFiled: August 20, 2003Date of Patent: March 1, 2005Assignee: Sylvan R.
