  • Patent number: 8022641
    Abstract: In an embodiment of the present invention, a light emitting diode (LED) recessed down light fixture comprises a housing, a reflector assembly mounted to the housing, and an LED circuit board attached to the housing over the reflector assembly. The LED circuit board includes a plurality of resistors electrically connected to the LED circuit board, a bridge rectifier, and a plurality of at least 80 miniature LEDs electrically connected to the LED circuit board and configured to provide light. The plurality of miniature LEDs are separated into a plurality of LED clusters. Each cluster is electrically connected to at least one resistor. Further, the plurality of miniature LEDs are arranged in a configuration such that a voltage differential across any two proximate LEDs is less than 36 volts. The down light fixture further comprises a lens cover attached to the top end of the reflector assembly.

  • Patent number: 6431723
    Abstract: A recessed lighting fixture includes a frame having an aperture and at least one mount and a reflector including at least one torsion spring configured to be received in the mount when the reflector is mounted to the frame. A recessed lighting fixture also includes a frame and a reflector. The frame includes an aperture and a pair of mounts separated around a circumference of the aperture in a first direction that differs from a distance in a second direction (i.e., by an angle of other than 180°). The reflector includes a pair of torsion springs separated around a circumference of the reflector in the same way. The reflector is designed to be received in the mount when the reflector is mounted to the frame. The aperture may be a noncircular opening. A junction box that can be used with a recessed lighting fixture includes a retaining spring and a plate having at least one edge having a slot cut into the edge. The retaining spring is mounted on the plate and includes a retaining portion and an outer edge.

  • Patent number: 6343873
    Abstract: A socket spring is designed to be installed in at least two different types of reflectors. The socket spring includes a base that can be connected to a lamp socket, a first arm and a second arm. The first arm extends from the base and includes a first bend near the base for use in connecting to a first reflector and a second bend further away from the base for use in connecting to a second reflector. The second arm extends from the base and includes a first bend near the base for use in connecting to the first reflector and a second bend further away from the base for use in connecting to the second reflector. Installing the socket spring in the first reflector includes mounting the first bends to the first reflector and installing the socket spring in the second reflector includes mounting the second bends to the second reflector.
