  • Self-contained solar powered lamp
    Patent number: 5062028
    Abstract: A self-contained photovoltaic powered light which is a stand alone unit. The solar cells which power the light are assembled and maintained within the top, or upper, portion of the self-contained unit. The solar cells are encapsulated within a resiliently deformable material to provide for contraction and expansion of the solar cells while at the same time providing protection from the elements for the assembly. A component tray assembly is rotationally secured to the upper portion of the lamp and a lens with decorative disks are rotationally secured to the component tray assembly.

  • Lens for low light level lamp
    Patent number: 4975816
    Abstract: A lens for use in a stand alone lamp utilizing low wattage light bulbs. The lamp is powered through the utilization of photovoltaic cells which charge a battery which then provides power to the bulb in the absence of the sun. The lens is constructed of a hollow body having horizontally disposed ribs formed on the exterior surface thereof with a clear, unobstructed lower portion closing the bottom of the lens.
