Abstract
A frame (10) supports a plurality of illumination modules (12) arranged in a common plane in a spoke-like pattern extending radially outward from a central axis. Each module includes a lamp (24) with a vertical filament (26) mounted in a faceted reflector (22) to direct a beam of light to a planar, dichroic mirror (30). The mirror (30) reflects the visible spectrum portion of the beam of light downward toward the central axis with all of the beams of light intersecting the central axis in a common plane to create an illumination zone of selected diameter. A disk (32) which is light transmissive at least in portions (34) forms a bottom cover for a cover (14). A handle (40) is rotatably mounted to the frame and connected by a mechanical linkage (50) with the reflectors for tipping the angle of the emitted light beams to adjust the diameter of the illumination zone.
