  • Patent number: 7682046
    Abstract: A lamp adjustment assembly for a light fixture includes a socket platform having a base and hollow neck. A socket mounts to the base. The interior of the hollow neck includes at least three spaced-apart cam followers. A cam having spiral grooves includes a first portion that fits at least partially within the interior of the hollow neck. The cam followers mate with the grooves. An adjustment knob is coupled to a second portion of the cam and rotatably coupled to a socket housing that at least partially encloses the lamp adjustment assembly. Alignment wings extend from the base of the socket platform and are sized to fit within slots in the interior of the socket housing. The slots prevent the socket platform from rotating and limit the linear range of motion of the socket platform. A spring applies force to the base and the adjustment knob.

  • Publication number: 20090109692
    Abstract: A lighting fixture having a socket housing and a removable lamp housing. The socket housing includes a socket for receiving a lamp and for connecting the lamp to a power supply. The lamp housing has a first end for emitting light from the lamp and a second end that is removably coupled to the socket housing. The lamp housing least partially encloses the lamp when connected to the socket housing. The second end of the lamp housing is wider than the lamp, so as to allow the lamp housing to be removed from the socket housing without first removing the lamp from the socket. Removing the lamp housing from said socket housing substantially exposes the socket to view and allows for installation of a lamp into the socket without having to re-position or re-aim the track light fixture.
