Abstract: An optical assembly for an LED light system with a LED light source is provided to control a light pattern of a light beam produced by the system, such as for spot or narrow flood light applications. The optical assembly includes a conical reflector with an interior reflective surface, a light diffuser and an optic holder. The light diffuser has an annular disk-shape with a central opening. The optic holder is mounted to a narrow open top of the reflector, and suspends the light diffuser inside of the reflector along an optical axis. The light diffuser is a cost-efficient optical element, which can be used in combination with the reflector to redistribute light in the system in order to soften a peripheral light area surrounding a center beam light area of the light pattern of the light beam, and reduce a harsh edge between the center beam and peripheral light areas.

Abstract: A downlight reflector assembly for a light-emitting diode (LED) light source includes a kicker reflector and an upper scoop. The kicker reflector has a reflector wall extending between a small top opening and a large bottom opening along a transverse axis. The reflector wall has an internal surface with an illuminated area and a non-illuminated area. The upper scoop is mounted in the small top opening of the kicker reflector and has a reflective multi-faceted surface with a concave curvature relative to the LED light source. The upper scoop extends from the top opening in part along the transverse axis and covering a portion of the top opening. The multi-faceted surface faces both of the illuminated area of the kicker reflector and the top opening for reflecting light rays received through the top opening towards the illuminated area.

Abstract: A monitoring system is configured to manage lumen depreciation in a lighting fixture and includes an optic housing, a light source with a light-emitting diode (LED), a processor, and a memory device. The memory device stores instructions that cause the monitoring system to measure elapsed time during which the LED light source emits the light and, based on the elapsed time, determine a current level of the emitted light. In response to the current level changing from an acceptable level to an unacceptable level, an alert is provided to show that the emitted light has reached the unacceptable level. A reset input is received to remove the alert for a predetermined period of time. Changes in status of the LED light source are indicated.

Abstract: A mounting assembly for a lighting fixture includes a fixture shield and an optic housing coupled at least in part to the fixture shield and having a light-emitting surface. The assembly further includes a heat sink movably coupled to the fixture shield in an initial low position, the heat sink being self-adjusting to one or more high positions relative to the fixture shield in direct response to displacement caused by one or more objects contained within the optic housing.

Abstract: Electronic circuitry for color-mixing in an LED light fixture during AC power dimming is disclosed to achieve adjustable color temperature. According to one embodiment, a dimmable LED light fixture has first, second, and third LED light sources, the first and second LED light sources producing white light, the third LED light source producing colored light, the LED driver configured to power the LED light sources by providing a single-channel variable-DC current source having two output terminals, and a current regulator for maintaining the current in the third LED light source path substantially constant as the LED driver output current is decreased when the AC power is reduced by the dimmer module, thereby altering the color of the light produced by the combination of the LED light sources.

Abstract: A downlight fixture includes an optic housing, a light-emitting diode (LED) array, and a lens-less reflector. The LED array emits directional light rays in a downward direction towards an illuminated target. The reflector is mounted within the optic housing and adjacent to the LED array. The reflector has a hyperbolic wall continuously extending between a narrow neck and a wide bell. The light rays are spread into a light beam within the reflector upon making contact solely with the hyperbolic wall.

Abstract: An adjustable assembly for conveying heat away from a fixture. The adjustable assembly includes a sliding plate having a first side for mounting the fixture thereon and a curved surface opposite the first side. The adjustable assembly also includes a fixed heat sink having a mating surface adapted to allow the curved surface of the sliding plate to slide from a first position to a second position while maintaining a substantially flush contact between the curved surface of the sliding plate and the mating surface of the fixed heat sink. At least one fastener is also provided for securing the sliding plate to the fixed heat sink alternately in the first position or the second position.

Abstract: A mounting assembly includes a stationary plate for supporting and linearly adjusting a recessed fixture in a parallel direction relative to structural framing members. Telescoping mounting bars are fixed to a building structure and allow adjustability of the stationary plate in a direction generally perpendicular to structural framing members. An adjustable plate has a plurality of linear guides received in a linear movable manner within a corresponding one of linear guide slots of the stationary plate. A linear locking member is adjustably secured in one of the linear guide slots such that linear movement of the adjustable plate is prevented relative to the stationary plate when the linear locking member is in a locked position, linear movement of the adjustable plate being allowed relative to the stationary plate in a direction parallel to the structural framing members when the linear locking member is in an adjustable position.

Abstract: A lighting assembly for a recessed luminaire includes a plaster frame for supporting the recessed luminaire and a pair of telescoping bars for attaching the plaster frame to framing support members. The telescoping bars include a first bar and a second bar, each of the bars having a generally S-shaped cross-sectional profile that is defined by a center curve joining a first area and a second area, which are generally hook-shaped and extend perpendicularly from the center curve in opposing directions. The first area of the first bar is overlappingly positioned at least in part within the second area of the second bar, and the first area of the second bar is overlappingly positioned at least in part within the second area of the second bar whereby the first and second bars are mated in an inverted and opposed adjacent relationship allowing sliding extension of the bars.
