Abstract
A stand-alone electric lamp which includes a base and a general area light source affixed to opposite ends of a stem to provide general area lighting. Disposed on the stem intermediate the base and the general area light source are a plurality of light sources for providing task lighting directable to specific areas. Each of the general area and task lights are individually controllable. Each of the task lights is adjustable universally to enable directing the light therefrom to the desired area.
Claims8
A stand-alone electric lamp comprising:
- a base member for supporting said lamp;
- an elongated hollow stem having first and second ends, said first end connected to said base member, said stem rising centrally from said base member;
- general area lighting means carried by said second end of said stem;
- a plurality of separate direct light reflectors affixed to said stem at spaced apart positions disposed between said base and said general area lighting means;
- a detachable rim carried by each of said separate light reflectors;
- electrical wiring means disposed within said hollow stem for providing electrical energy to lamps disposed within sad reflectors and said general area lighting means;
- and
- switch means for individually controlling the application of electrical energy to each of said lamps.
