  • Patent number: 5997160
    Abstract: A stand alone electric lamp for illumination which includes a tungsten-halogen bulb as the illuminating member. The lamp includes a support member, an upwardly directed open pan affixed to the support member in which the tungsten-halogen light bulb is disposed, a protector member disposed over the open pan to prevent foreign objects from coming into contact with the tungsten-halogen light bulb and a thermally activated switch. The protector member is substantially transparent to light from the tungsten-halogen bulb to allow light therefrom to pass through the protector member in a substantially unobstructed fashion. The thermally activated switch is disposed within the open pan for interruption of the application of electrical energy to the tungsten-halogen light bulb when temperatures at the protector member reaches a predetermined level.

  • Patent number: 5567043
    Abstract: A torchiere lamp having a base and an upwardly directed general area lighting fixture supported upon a stem extending from the base. A task light is supported upon a rod which passes through a pair of anchors secured to the stem so that the rod is disposed substantially parallel to the stem. One of the anchors carries a locking member in the form of a threaded thumb screw which may be loosened to permit vertical and rotational movement of the rod for positional adjustment of the task light. The task light includes a reflector or shade pivotally attached to the rod to thereby permit further rotational and pivotal adjustment of the reflector.
