  • Patent number: 6652113
    Abstract: A dual-mode light unit, fitting closely against a vertical wall surface, indirectly illuminates a nearby ceiling region with a uniform wash and provides a functional task light component while providing an unusual luminous visual accent effect from a major lower region of the unit. A fluorescent lamp is located about one-third way down from the top of the shallow vertically-elongated enclosure. The lamp is concealed behind a lamp shield running across the front. An upper reflector, offset upwardly from the lamp and extending to the top of the unit, is made with a smooth reflective surface shaped to distribute the upward illumination field from the lamp uniformly as a ceiling wash. A lower luminance panel, offset downwardly from the lamp and extending to the bottom of the unit, a matte surface that picks up highlights from a controlled field of downward illumination from the lamp, creating 14B ′ as an unusual soft restful decorative effect while also functioning as a task light.

    Abstract: A dual-mode indirect light unit designed for easy installation, fitting closely against a vertical wall surface, indirectly illuminates a nearby ceiling region with a uniform wash and also provides a functional task light component while also providing an unusual luminous visual accent effect from a major lower region of the unit. A horizontally oriented fluorescent lamp is located about one-third way down from the top of the shallow vertically-elongated enclosure. The lamp is concealed behind a lamp shield running across the front. A concave upper reflector, offset upwardly from the lamp and extending to the top of the unit, is made with a smooth reflective surface shaped to distribute the upward illumination field from the lamp uniformly as a ceiling wash.
