The present invention is based on a fastening system for flush mounting a device in a wall and/or ceiling and/or similar through a hole and on the device that comprises the fastening system, wherein said fastening system comprises a gripping means and a securing system. The fastening system enables the device to be flush mounted in a wall and/or ceiling and/or similar through a hole such that the perimeter of the visible face of the device is flush with the wall and/or ceiling and/or similar.

The housing provides recessed lighting with a detachable trim. The housing provides an attachment base for securing the trim adapter and trim. The housing provides a sealed housing that limits the number of bugs, pests, and animals from entering the structure or building a nest within the lighting. The housing provides a removable top cover that secures onto the housing. The top cover can be removed to expose vents within the housing. The top cover installs onto the housing to close the vents. The housing also provides an opening for securing a junction box to the housing for installing the wiring needed for the light. The junction box may be installed onto the housing or may be removed from the housing depending on the installation.

A dual output downlight luminaire includes a housing that forms at least a first cavity. A partition extends from a portion of the housing and at least partially forms a boundary between the first cavity and an annular second cavity. A first light source emits a first light that is centered about an optical axis and propagates toward a first output aperture. An optic redirects the first light to form a first light beam that exits the luminaire through the first output aperture. A concentrated portion of the first light beam subtends an angle of 60 degrees or less and is centered about the optical axis. A plurality of second light sources, within the second cavity, emit a second light that exits the luminaire through an annular second output aperture. The first and second light sources are independently controllable with respect to each other.

A mounting system includes a threaded body that is configured to securely retain an electronic component therein. The threaded body includes a core that defines an inner cavity extending therethrough, and a bottom flange that extends radially outward from an annular bottom edge of the core. The threaded body includes a plurality of fins that are substantially vertically oriented and extend radially outward from the core. The outer edges of the plurality of fins are indexed to collectively form a helical structure that defines a screw thread. The mounting system also includes a nut member that defines a center cavity that extends therethrough and includes an inner flange that defines a complementary screw thread. The mounting system is installed in the ceiling tile by removably coupling the nut member to the threaded body such that the ceiling tile is clamped between the bottom flange and the nut member.

Provided is an adaptable fire-resistant housing for a light fixture, comprising: a. a junction box made from steel, the junction box having an opening on a bottom configured to receive the light fixture; and b. an adjustable ring attached to the bottom of the housing, the adjustable ring having an opening configured to be attached to the light fixture or an adapter ring; wherein the light fixture or the adapter ring is attached to the adjustable ring.

A junction box includes a first cover plate that covers a first open side defined by a main body, and a second cover plate that covers a second open side defined by the main body. The second cover plate includes a mounting pad to attach an electrical component thereto. The electrical component is disposed in an inner cavity defined by the main body when the second cover plate is in a closed position. Further, the junction box includes a fastening device that retains the first cover plate and the second cover plate in the closed position and operates without interfering with a mounting structure in which the junction box is disposed. Furthermore, the junction box includes chamfer walls and wire traps disposed thereon to receive and pass electrical wiring cables into the junction box therethrough.

Controlled environment light fixture configurations include an LED light source. The light fixtures can be installed and removed from below the ceiling. The light fixture can be installed and removed without opening the lens frame of the light fixture. The light fixture includes a sealed housing and seals to the ceiling when installed. The light fixtures are provided in exterior dimension sizes that allow the fixtures to be installed in a variety of controlled environment ceilings in recessed configurations. The lower surface exposed to the controlled environment is free of welds and grinds in order to provide a corrosion resistant surface.

Provided is an adaptable fire-resistant housing for a light fixture, comprising: a. a junction box made from steel, the junction box having an opening on a bottom configured to receive the light fixture; and b. an adjustable ring attached to the bottom of the housing, the adjustable ring having an opening configured to be attached to the light fixture or an adapter ring; wherein the light fixture or the adapter ring is attached to the adjustable ring.

A detachable panel light includes an outer casing, light emitting members, and magnetic members. The outer casing includes a detachable covering plate and holding members respectively at two sides of the detachable covering plate. One surface of the magnetic member is attached on an inner surface of a receiving groove of the outer casing, and one surface of the magnetic member is attached on the corresponding holding member. The light emitting members are assembled on the outer casing. Each of the light emitting members includes a supporting frame assembled on the corresponding holding member, a light source plate assembled on the supporting frame, and a lightshade assembled on the supporting frame to cover the light source plate. Accordingly, the light emitting members are modularized and attached on the outer casing by the magnetic members. Therefore, the maintenance and the replacement for the LED modules can be convenient.
