Abstract: A system can comprise tabs and notches or a twist-and-lock mount for detachably mounting components adjacent a light emitting diode that is utilized for illumination, for example in a luminaire. Representative mounted components can include protective covers and optics for managing light emitted by the light emitting diode. The tabs and notches can be located rear of an aperture in a recessed lighting fixture or in a cover of a luminaire, for example. That cover, or another cover that may not utilize a releasable mount, can extend circumferentially about a periphery of a light emitting diode to cover and protect wiring for the light emitting diode and to hide the wiring from view by people occupying an illuminated space.

Abstract: 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.

Abstract: A light emitting diode (LED) lighting system includes an enclosure, a trim, and at least one attachment mechanism. The enclosure can include at least one heat-generating device and an enclosure collar, where the enclosure is made of a first thermally conductive material. The trim can include a trim collar and at least one wall that defines a passage, where the trim collar abuts the enclosure collar, and where the passage has a reflector and a LED is disposed therein. The least one attachment mechanism can removably couple the trim collar to the enclosure collar, where the at least one attachment mechanism includes a back plate that is mechanically coupled to an upper flange and a lower flange, where the upper flange contacts the enclosure collar and the lower flange contacts the trim collar.

Abstract: A connection to an electrical supply for a lighting system can be configured to facilitate deployment of the lighting system in a cramped space, for example in a shallow overhead plenum. The lighting system can comprise a housing for the light source. One or more sides of the housing can extend about the light source, for example circumferentially around the light source or otherwise laterally enclosing the light source. The electrical connection can be provided at a side of the housing, resulting in a low profile.

Abstract: A light emitting diode (LED) lighting system includes a primary enclosure and a secondary enclosure. The primary enclosure can include a fastening feature of a secondary enclosure receiver that is positioned adjacent to an aperture in the primary enclosure. The secondary enclosure can include a corresponding fastening feature that mechanically couples to the fastening feature of the primary enclosure, where the secondary enclosure surrounds the aperture when the secondary enclosure is mechanically coupled to the primary enclosure. The secondary enclosure can further include a passage through which a wire that traverses the aperture in the primary enclosure passes.

Abstract: Splice enclosures for housing wire splice connections in a luminaire are described herein. The splice enclosures may each include a cover that includes one or more tabs extending substantially orthogonal from the cover, and a bottom housing (or body) having a base and two side walls and two end walls. Moreover, at least one of the side walls includes an outer surface having one or more protrusions for engaging the tab(s) of the cover. Additionally, at least one of the end walls includes a wire routing aperture. In some embodiments of the invention the cover may include at least one notched protrusion that aligns with the wire routing aperture to retain wires exiting an end wall of the splice enclosure.

Abstract: 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.
