  • Patent number: 7488085
    Abstract: 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.

  • Patent number: 7347587
    Abstract: 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.
