An integrated ceiling device (80, 120) includes an electronics assembly (56) and a mechanical arrangement (20). The mechanical arrangement includes a housing (22), a heat dissipating structure (24), and support arms (26). The housing is configured to retain the electronics assembly. The heat dissipating structure includes a lamp seat (50) for receiving a light source (54), and a central opening (34) surrounded by fins (36). The support arms extend between and interconnect the housing with the heat dissipating structure. The housing is positioned within the central opening and is spaced apart from the fins of the heat dissipating structure to enable a free flow of air in an air gap (42) between the housing (22) and the structure (24). The electronics assembly may include a plurality of elements (160, 162, 164, 166) retained in the housing which are spaced apart from the heat dissipating structure.

A plaster frame assembly includes a base plate that has a base wall and a plurality of side walls that extend substantially perpendicular to the base wall from a perimeter of the base wall. The base wall includes at least one regressed pad that has a plurality of perforations. The plurality of perforations receive one or more securing fasteners therethrough to secure or fasten the base plate to the ceiling. Furthermore, the base wall includes one or more sealing features that provide an air-tight sealing for a recessed housing can received through and retained in a can receiving opening formed in the base wall. The one or more sealing features include multiple collar sections that define a groove for receiving a sealing member, and one or more sealing tabs disposed between the multiple collar sections and configured to seal one or more adjustment apertures of the recessed housing can.

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 wall pack light fixture including a front cover having a recess with a contact surface and at least one electronic component mounted on the contact surface, a rear enclosure having a forward-facing open front with a forward-facing front edge, and a hinge having a first portion connected to the front cover and a second portion pivotably coupled to the first portion, the second portion connected to the rear enclosure on an exterior side surface of the rear enclosure behind the forward-facing front edge, wherein the front cover is rotatable about the hinge between a closed configuration, in which the contact surface is against the forward-facing front edge, and an open configuration.

Mounting brackets for installing extruded profiles on surfaces, such as walls, ceilings, tile surfaces, etc., may be resilient. The mounting bracket may include a coil spring designed to rotate or pivot with respect to a main body. The spring may apply force to a rear of the surface thus holding or maintaining the mounting bracket in place. The mounting bracket may be a flat spring. The flat spring may apply force to side surfaces of an opening formed in the surface thus holding or maintaining the mounting bracket in place. The mounting bracket may hold an elongated profile designed for recessed LED lighting to the surface.

A blank for an enclosure for a recessed light fixture in an attic comprises a sheet of a thermally resistant material subdivided into a plurality of square panels by living hinges. The panels are foldable to provide a housing for the recessed light fixture. A package of blanks is constituted by a pair of such sheets, each sheet having a panel pivoted against an adjacent panel of same sheet in a back-to-back relationship when the sheets are juxtaposed relative to one another.

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.

An integrated ceiling and light system that incorporates a light module into a ceiling tile. The system may include a grid support system suspended from an overhead support structure that includes at least one grid support element and first and second ceiling tiles supported by the grid support element in an adjacent manner. A nesting cavity may be formed into the first and second ceiling tiles such that a light module may be disposed within the nesting cavity and coupled to the first and second ceiling tiles. The ceiling tiles may be of the type that conceals the grid support element on which it is supported. In one alternative embodiment, the light module and a nesting region of the ceiling tile may include corresponding edge profiles to facilitate mating therebetween to enable coupling of the light source to the ceiling tile.

A housing for a luminaire is disclosed. The housing can include a housing top and a housing body coupled to each other. The housing body can include at least one wall that is bendable to form a cavity. The housing body can also include at least one first housing body coupling feature disposed on a first end, and at least one second complementary housing body coupling feature disposed on the first end adjacent to the at least one first housing body coupling feature. The housing body can further include at least one second housing body coupling feature disposed on a second end, and at least one first complementary housing body coupling feature disposed on the second end adjacent to the at least one second housing body coupling feature.

The present invention provides an illumination device in which an organic EL panel is detachable from a mounting member; the panel has a panel body and a fixing member. The panel body has an emission surface on its front and a circuit board on its rear. The fixing member has a main body and a raised part that is disposed on a rear of the panel and raised with respect to the main body to circumvent the circuit board and to protect the circuit board. The raised part includes a raised-side engagement part protruding in a direction crossing a raised direction. The mounting member has an attachment side main body and an attachment side engagement part. The attachment side engagement part extends from the attachment side main body to form a step. The engagement parts engage together when the panel is attached to the mounting member.
