A downlight fixture housing fabrication method in which upper and lower downlight fixture housing portions are formed in separate steps and joined by press-fitting, a bonding agent, pinning, and/or threaded engagement.

A sealed luminaire includes a light engine that has a housing assembly that defines a light emitting opening and a lightguide that is disposed in the housing assembly. The lightguide is configured to receive light from a light source through an edge thereof and emit the light through a major surface thereof and the light emitting opening. Further, the sealed luminaire includes a sealing assembly. The sealing assembly includes a protective lens that is coupled to the housing assembly of the sealed luminaire such that the protective lens covers the light emitting opening, and a gasket that is coupled to the protective lens. A mounting bracket is configured to mount the sealed luminaire in a mounting structure such that the sealed luminaire is clamped between the mounting bracket and the mounting structure and the gasket creates a seal between the sealed luminaire and the mounting structure.

A lighting device assembly includes a light source and an optic attached to a first heat sink member, a second heat sink member connected in thermal communication with the first heat sink member, and an aperture member connected to the second heat sink member. The aperture member has an inner surface having steps surrounding a light exit opening to reduce a thickness dimension. The edge of the light exit opening is angled radially outward toward its light exit side. A third heat sink member is connected in thermal communication with the second heat sink member, and has a plurality of openings to receive one or more plaster materials. The third heat sink member has a first region and a second region at least partially surrounding the first region, the second region has a reduced heat conduction capability relative to the first region, to inhibit a transfer of heat to the outer perimeter of the body of the further heat sink member.

A method and system for providing an improved recessed luminaire includes providing the ability to rotate or shift the position of the junction box within the system. The improved system also provides an ability to shorten lengths of the hanger bar assemblies in an efficient manner during installation of the luminaire. A geometry of the end of the hangar bar assemblies may be modified to provide a more efficient design that also helps support fasteners. Additional improvements may include those for a spring to lock a door of the junction box; improvements for locking hanger bars to a plaster plate; improved mounting tabs for the plaster plate; an improved thermal protector case with enhanced coupling mechanisms; and improvements to a spring for locking a door of the junction box that improve compactness for the system to aid in shipping the system.

A lighting apparatus includes a first conductive unit, an installation bracket, a second conductive unit, a light body and a top cover. The first conductive unit is used for connecting to an external power source. The installation bracket is fixed to an installation platform. The first conductive unit is disposed on a first side of the installation bracket. The top cover is used for disposing the second conductive unit and the light body. The top cover is detachably connected to the installation bracket from a second side of the installation bracket.

A lighting arrangement operable to emit light is disclosed herein. The lighting arrangement can include a mounting bracket and a luminaire. The mounting bracket can have first and second bracket portions positioned about a central longitudinal axis of the mounting bracket. The mounting bracket can also include at least one pair of telescoping shafts interconnecting the first and second bracket portions. The mounting bracket can also include at least one spring positioned to bias the at least one pair of telescoping shafts to an extended configuration. The luminaire can have at least one spring member selectively engageable with at least one shaft of the at least one pair of telescoping shafts to selectively interconnect the luminaire and the mounting bracket.

A retrofit trim lighting device is provided. In example embodiments, the retrofit trim lighting device comprises a bracket comprising an opening; at least one torsion spring secured to the bracket and configured to mount the retrofit trim lighting device within a recessed housing; a retrofit housing comprising at least one light engine; and an engagement element. The engagement element is secured to the retrofit housing through the opening of the bracket such that, when so secured, the retrofit housing and the bracket are rotatable relative to one another.

A downlight apparatus includes a light source module, a cup housing, and a rotation structure. The cup housing has a surface rim and cup body. The surface rim defines a light opening. The surface rim covers an installation hole of an installation cavity. The multiple LED modules are disposed in the container space for emitting light out of the downlight apparatus from the light opening. The rotation structure selectively defines a first exterior diameter and a second exterior diameter. The first exterior diameter being larger than the second exterior diameter and an installation diameter of the installation hole. The second exterior diameter is smaller than the installation diameter.

A system for mounting pendant lighting fixtures includes an interface component adapted to be at least partially retained in an opening defined by a ceiling. The interface component defines at least one aperture to accommodate a hanging support extending through the opening and configured to support a pendant lighting fixture. The system includes a cover plate defining at least one aperture to accommodate the hanging support. The system also includes at least one magnetic element operable to exert a magnetic bias on the cover plate to secure the cover plate against the interface component and at least partially cover the opening.

A junction box-driver assembly includes a housing that is configured to route electrical wiring to a luminaire therethrough and house a driver module therein. The housing includes a back plate that defines a junction box cavity and a driver cavity that is disposed adjacent to and in fluid communication with the junction box cavity. Further, the housing includes a junction box cover that is coupled to the back plate and configured to cover the junction box cavity that is configured to route the electrical wiring therethrough and/or enclose wire connections therein. Furthermore, the housing includes a driver cavity cover that is removably coupled to the back plate to cover the driver cavity that is configured to house the driver module therein. The junction-box driver assembly further includes a mounting strut that is removably coupled to the housing and configured to releasably lock the junction box-driver assembly to a mounting frame.
