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.

Abstract: A strobe warning light comprises an elongated strobe lamp having a longitudinal axis, a lamp support supporting the lamp in a predetermined position, and a reflector on the support that includes a first surface positioned on one side of a first reference plane that includes the lamp axis and a second surface spaced apart axially of the lamp from the first surface and positioned on the other side of the first reference plane. The first and second surfaces face generally toward each other and are configured and oriented to receive light from the lamp and reflect it in opposite directions along paths generally parallel to the lamp axis and on opposite sides of the first reference plane so that each one of the first and second surfaces directs reflected light predominantly past the other of the first and second surfaces. The reflector also has a third surface that is configured and oriented to reflect light from the lamp in divergent directions generally radially with respect to the lamp axis.
