  • Patent number: 4870548
    Abstract: 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.

  • Patent number: 4814961
    Abstract: A light fixture (10) including a bulb/lens assembly (12), a hollow post (14) and a ground stake (16). An assembly ring (18) having inner and outer "fingers" (104 and 106, respectively) securely connects the bulb/lens assembly (12) to the post (14). Bulb/lens assembly (12) includes a lens (28) which carries a plurality of louvers (40, 42 and 44). Some of the louvers include legs (46, 50) and slots (60, 62) so that the distance between the louvers can be adjusted to vary the appearance of light fixture (10) and the amount of light produced thereby.

  • Patent number: 4774648
    Abstract: A low voltage light fixture (10) including a bulb/lens assembly (12) mounted atop an integral post/stake assembly (14). Post/stake assembly (14) includes a hollow tubular portion (20) and a ground stake portion (22). A preferred post/stake assembly (14) is formed from a single piece of plastic, and consists of a pair of elongate legs (94, 96) which are joined to a female adapter (90) through the use of a pair of "living hinges" (100). To assemble post/stake assembly (14), it is merely necessary to draw legs (94, 96) together until a pair of locking fingers (104) extending from leg (94) engage a pair of slots (110) formed in the other leg (96). Light fixture (10) also preferably includes a unique internally ribbed lens which includes a large plurality of internal side ridges (114) and a smaller plurality of top ridges (116).
