摘要:
A convertible light fixture (10) capable of selectively functioning as a spotlight or floodlight. A preferred light fixture (10) includes a ground stake (12) supporting a bulb/lens assembly (14). An electrical cable (16), protected by the preferred S-shaped ground stake (12), makes contact with the bulb/lens assembly (14) at the rear thereof. More specifically, a pair of prongs (60), which also support a bulb (62), protrude from the rear of bulb/lens assembly (14) and make contact with electrical cable (16). Preferred bulb/lens assembly (14) includes a stationary housing (40) and a rotatable focus ring (70) wherein rotation of the latter relative to the former causes axial movement of a reflector (80) relative to bulb (62) to change the degree of focus of the light beam produced by fixture (10). Another feature of preferred bulb/lens assembly (14) is a lens (90) which produces a rectangular light beam adjustable in orientation.
