ABSTRACT:
A self-positioning lamp fixture with an integrally formed unitary support structure, including a self righting rounded lower wall terminating in a flat portion to stabilize the lamp structure when in its upright position. A continuous cavity extends throughout the integrally formed support structure making it lightweight. A weight receiving recess is provided at the lower end having an open wall across the flat portion of the structure's lower wall to receive a cylindrical weight therein. The cylindrical weight is removable and is held in the weight receiving recess by removable lag screws. The cylindrical weight has a planar bottom wall which covers the open wall across the flat portion of the structure's lower wall when the cylindrical weight is secured in place within the weight receiving recess. A ventilation and cooling system is provided to cool the lamp assembly, comprising ventilation intake and discharge apertures and a blower to flow cooling air into, through and out of the lamp fixture and its lamp assembly. A flexible sheet reflector is provided which may be folded up when not in use and held in its folded up position on the lamp fixture until such time as it is to be used again. An annular recess is provided to receive and store the electrical cord when not in use. An auxiliary convenience outlet is provided on the wall of the lamp fixture. In a modification of the invention, a universal ball and socket swivel mount is provided for the lamp assembly at the upper end of the lamp fixture to enable pivoting the lamp to any desired pivotable position.
