A light emitting diode (LED) driver case includes a housing, driver circuitry, an recessed area in the housing, and a luminaire disconnect. The luminaire disconnect is coupled to the recessed area in the housing and extends toward an aperture in a top plate of a LED module. The luminaire disconnect can be fixedly or removably coupled to the recessed area in the housing. When the luminaire disconnect is removably coupled to the recessed area, one or more of a number of retaining features can be used to prevent the luminaire disconnect from moving or to limit the movement of the luminaire disconnect.

In an example embodiment of the present disclosure, a light fixture assembly comprises a surface mount light fixture. The surface mount light fixture comprises a trim having a first shape. The trim comprises an outer trim perimeter and an inner trim perimeter. The inner trim perimeter defines an orifice through which light is emitted, wherein the outer trim perimeter includes a chamfered edge. The light fixture assembly further includes a skin having a second shape similar to the first shape and configured to at least partially cover the trim. The skin includes an outer skin perimeter configured to surround the outer trim perimeter, an inner skin perimeter configured to surround the inner skin perimeter, and a raised coupling feature configured to grip the chamfered edge of the trim. The skin is coupled to the trim via the engagement of the raised coupling feature and the chamfered edge.

A light fixture mounting assembly comprises an extender and a bracket. The extender comprises a junction box end configured to couple to a junction box, a fixture end located a distance from the junction box end, a perimeter wall extending from the junction box end to the fixture end, and a first set of screw holes formed within the junction box end or the fixture end. The bracket comprises a raised portion and one or more flange portions coupled to the raised portion. The one or more flange portions have a second set of screw holes formed therein. The one or more flange portions are disposed against the fixture end of the extender. The raised portion is disposed through an opening formed in the extender, and the second set of screw holes of the bracket is aligned with the first set of screw holes.

An electrical connection adapter for an existing light fixture is described herein. The adapter can include a housing having at least one wall that forms a chamber disposed between a top side and a bottom side of the housing. The adapter can also include a first connection feature disposed within the top side of the housing and configured to couple to an electrical connector for the existing light fixture. The adapter can further include a second connection feature disposed within the bottom side of the housing. The adapter can be configured to couple to a light source of a retrofit light fixture. The adapter can also include a power transfer device disposed within the chamber of the housing, where the power transfer device has a first end electrically coupled to the first connection feature and a second end electrically coupled to the second connection feature.

The luminaire includes a light emitting diode (LED) module that includes a heat sink with an outer wall defining a top cavity and a bottom cavity and a mounting flange generally positioned along the bottom of the outer wall. A LED light source is positioned within the bottom cavity and in thermal communication with the heat sink. The bottom surface of the mounting flange includes one or more alignment features or keys extending out from the bottom surface. A trim having a corresponding alignment aperture is matingly engaged by positioning all or a portion of the alignment feature into the alignment aperture to ensure proper orientation of the trim with the LED module and to provide sufficient surface area for good thermal transfer between the heat sink and the trim.

A recessed light fixture has a plurality of fasteners for securing a can or top hat of the recessed light fixture to a substrate, e.g., sheetrock ceiling and/or open frame mounting plate. Each of the plurality of fasteners comprise a clevis bracket, a clevis hook having perpendicular tabs that rotatably attach the clevis hook to the clevis bracket. When the recessed light fixture is inserted into an opening of the substrate, the clevis hooks rotate out of the way into slots in a wall of the recessed light fixture can. Once the clevis hooks clear the substrate, the clevis hooks rotate back through the wall of the recessed light fixture can. Then the clevis brackets are slideably moved toward the substrate, whereby gripping portions of the clevis hooks will engage the substrate and thereby hold the recessed light fixture to the substrate.

An optical attachment feature of a light-emitting diode (LED) lighting system includes an enclosure, a trim, a reflector, and a diffuser. The enclosure can include an enclosure wall forming a cavity and an enclosure collar having a first profile. The trim can include a trim collar that abuts to the enclosure collar, wherein the trim collar has a second profile. The reflector can include an outer surface, an inner surface having reflective material disposed thereon, and a reflector collar having a first optical attachment mechanism. The diffuser can include a diffuser collar, where the diffuser collar can include a second optical attachment mechanism and a third optical attachment mechanism, where the second optical attachment mechanism can couple to the first optical attachment mechanism, and where the third optical attachment mechanism is disposed within a feature formed by the first profile and the second profile when the enclosure collar is mechanically coupled to the trim collar.
摘要:
A recessed light fixture includes a thermally protected light emitting diode (“LED”) module. The thermally protected LED module includes a thermal protector positioned in series between a source of electrical power and an LED driver and is configured to open a circuit to prevent power from being supplied by the power source to the LED driver for an LED package when a thermal rating or activation temperature of the thermal protector is exceeded. For example, the maximum operating temperature of the LED driver may be 90 degrees Celsius, and the thermal rating of the thermal protector may be 80 degrees Celsius, and when the temperature of the driver or a mounting bracket upon which the driver is mounted reaches 80 degrees Celsius, the thermal protector opens a circuit and removes current flow from the power source to the driver, thereby removing power to the LED package.

An electrical box that allows for separate wire connection areas for low voltage and line voltage wiring within a single box. The electrical box includes a voltage divider positioned within the box that divides the box into two portions, providing a low voltage wiring connection area that is separate from the line voltage wiring connection area. The electrical box also includes multiple knockouts, each covering an opening that provides a passageway from the interior of the box to the exterior of the box. At least one knockout and associated opening are positioned to provide access to the low voltage wiring connection area and another knockout and associate opening is positioned along to the box to provide access to the line voltage wiring connection area. The box provides an electrical junction for a luminaire, such as a downlight, or other electrical device.
