Abstract: A housing assembly for a recessed lighting system includes a housing with integrally formed cable routing features, mounting features, and alignment features. The integration of multiple features into the housing is enabled by forming the housing from a polymer using an injection molding process instead of sheet metal. For a new construction installation, the housing includes integrally formed bar hanger holders to support and guide bar hangers for installation onto two or more support structures, nail-in features for installation onto a single support structure, and one or more alignment features to position the housing against the single support structure when the nail-in features are used for installation. For a remodel installation, the housing includes a flange to abut a bottom surface of a ceiling and one or more spring clips mounted to the housing to abut a top surface of the ceiling.

Abstract: A housing assembly for a lighting system includes a single metal housing that functions as a can housing and a junction box and has a round geometry to improve ease of installation and support trims with smaller flanges. The housing includes a top component and one or more sidewall components. The sidewall component defines the desired round shape of the housing while the top component provides one or more flat surfaces to support one or more knockout features. For a remodel installation, the housing assembly further includes a spring clip assembly with a mounting ring and multiple spring clamps to securely couple the housing assembly to a drywall panel of a ceiling. For a new construction installation, the housing assembly further includes a bar hanger assembly to couple the housing to one or more support structures within the ceiling.

Abstract: Embodiments are directed to a lighting system including a junction box for accommodating a light source assembly, and which is configured to allows for additional components such as separate drivers or emergency ballasts to also be included in the lighting system together with the light source assembly. In embodiments, the junction box is mounted on a pan style frame. In some embodiments, the lighting system includes a test switch mounted on a trim piece that is accessible from below a ceiling in which the lighting system is installed, and which allows for an emergency power supply to be verified.

Abstract: Apparatus and methods for controlling correlated color temperature (CCT) and lighting intensity in lighting fixtures are described. The CCT and intensity may be controlled independently over conventional AC wiring using a conventional dimmer. A lighting controller that resembles a conventional dimmer and that can be installed in place of a dimmer may be used instead of a conventional dimmer to access more control functionalities, still using conventional AC wiring. Wireless communication with the lighting fixture and/or lighting controller are possible.

Abstract: A lighting assembly includes a heat-sinking housing, a lens, a light source module including at least one LED, and an AC to DC converter to receive an AC voltage and supply regulated electrical energy to power the light source module. The housing includes a closed rear wall and a sidewall that defines a housing cavity containing the at least one LED. The closed rear wall and the sidewall are formed of a heat conductive material to conduct heat generated by the light source module. The assembly has a front end face, and at least one exterior width dimension of less than 3½ inches. In one example, a circular recess defined along an inner edge of the front end face contains the lens in the assembly. In another example, the front face includes a tool-less mating mechanism, for example a twist-and-lock mechanism comprising multiple flanges and/or slots.

Abstract: A lighting module includes a heat sink with a sidewall and a partition defining two cavities, a LED light source disposed in one cavity to emit light, a driver module disposed in the other cavity with driver circuitry to provide electrical power to the light source, and an optical assembly to provide a desired emission profile. The optical assembly is field-changeable and includes a cover lens with snap-fit connectors to facilitate removal and replacement. The optical assembly further includes either a reflector coupled to the cover lens or an optical lens coupled to the heat sink via an optic holder. In some examples, the driver circuitry facilitates dimming of the light source. The heat sink also dissipates heat generated by the light source and the driver circuitry to maintain desired operating temperatures and thereby facilitate increased light output.

Abstract: A junction box having a cavity to contain electrical wires that provide a connection to a building mains voltage from an electrical system of a building is coupled to a plurality of telescoping hanger bars to hold the junction box in a wall or ceiling in the building. Each telescoping hanger bar is extendible and/or retractable to vary a length of the hanger bar. A position of the junction box is adjustable along the length of each telescoping hanger bar. In one example, the apparatus does not include a can, separate from the junction box, to contain a lighting device of a recessed lighting assembly.

Abstract: A fire-resistant, recessed lighting unit that obviates the need for a separate junction box and a separate incandescent “can”. Other embodiments are also described and claimed.

Abstract: An LED downlighting apparatus includes a housing with a sidewall having a front facing edge and a back facing edge positioned adjacent to a ceiling when the LED downlighting apparatus is installed in an opening of the ceiling. A depth of the sidewall is less than one inch and a thickness of at least a portion of the sidewall is less than three millimeters. An LED board and a lens are coupled to the housing. The lens is disposed with respect to the LED board such that the lens is illuminated from a back side. One or more mechanical couplers snap fit the apparatus to a junction box installed and positioned above the ceiling such that when the apparatus is snap fit to the junction box through the opening of the ceiling, the housing appears to be surface mounted to the ceiling.

Abstract: A lighting module includes a heat sink having a sidewall and a partition that define a first cavity and a second cavity. A driver enclosure is disposed in the first cavity to electrically insulate a driver from the heat sink. The driver enclosure substantially fills and covers the first cavity. A light source that emits light is disposed in the second cavity together with an optical element that redirects the light. A retaining ring/optic cover covers and encloses the second cavity. The lighting module is shaped and/or dimensioned to fit into a space having a width less than 2.4 inches, a height less than 2.25 inches, and/or a volume as small as 18 cubic inches. The heat sink may also include a receptacle to couple a trim to thermally and electrically couple the trim to the heat sink to dissipate heat and to ground the trim.
