Circular Tube Patents (Class D26/79)
  • Lighting apparatus
    Patent number: 7390106
    Abstract: The present invention comprises a method of enhancing illumination by a variety of lamp types through the use of reflective technologies, for example, replacement of expensive high intensity density of mercury vapor lamps with low wattage fluorescent tubes having at least one and in some cases, up to three reflective surfaces for focusing otherwise lost light toward a target illumination area. Further, the placement of light sources at the focal point of said reflective surfaces aids in optimizing the amount of light focused in a desired direction.
