  • Patent number: 7517119
    Abstract: An externally adjustable directional canopy luminaire is disclosed that may be easily and quickly adjusted from the outside of its housing to direct light toward a particular target area. The luminaire includes a lamp shroud assembly including a door frame, a shroud and a lamp socket which is connectable to an electrical power source to power a replaceable lamp, an external adjustment member, and an internal mechanism movably connected to the external adjustment member through the shroud and indirectly connected to a portion of the lamp socket, wherein adjustment of the external adjustment member can alter the angle of direction of the lamp socket and thus the direction of light emitted from the replaceable lamp through the opening of the shroud.

  • Patent number: 5599094
    Abstract: A mounting system for luminaire assemblies includes a mounting fixture which can be inserted into a tubular pole and secured therein without the need for complicated fasteners or tools. Specifically, the mounting fixture includes a cylindrical fitting with a tapered threaded section in which the depth of the groove forming the threads decreases upwardly along the fitting. A generally circular wire clip is seated within the tapered groove and upon rotation of the fitting relative to the tubular pole an end or detent of the clip engages the inner surface of the pole thereby prevent rotation of the clip. Continued rotation of the fitting relative to the pole advances the clip upwardly in the threaded section toward the more shallow portions of the groove thereby forming a friction fit between the expanding clip, the mounting fixture and the pole.
