ABSTRACT:
A light fixture (10) adjustable in focus and/or beam direction. Light fixture (10) is of the "vertical" or "downlighting" type, and preferably includes a bulb/lens assembly (16) mounted atop a relatively short post (14). Bulb/lens assembly (16) includes a lens (30) which rotatably carries a cap (72). Inside lens (30) and beneath cap (72) is a bulb (42) and a reflector assembly (48). Reflector assembly (48) includes a reflector holder (50) having a plurality of outwardly-extending posts (70) which are first received by vertical slots (46) in lens (30) and finally by cam grooves (80) in cap (72). Rotation of cap (72) relative to lens (30) causes cam grooves (80) to act upon posts (70) to move reflector assembly (48) relative to bulb (42). Reflector assembly (48) can be moved vertically relative to bulb (42) to adjust the width or focus of the light beam; and/or tilted vis-a-vis bulb (42) to adjust the direction of the light beam.
