A downlight apparatus is designed to be installed in a cavity of a ceiling. The downlight apparatus includes a base part, a major part and a connector. The base part has a shape to be fixed in the cavity of the ceiling. The base part has a base housing for defining a through hole and a light window. The major part includes a major housing, a light source and a driver circuit. The connector connects the major housing and the base housing. The connector provides multiple candidate positions for a user to configure to change a relative position of the base part and the major part so as to change an output light defined determined by the light window and the light source.

The downlight apparatus includes a surface rim, a rotation bracket, a bowl housing and a light source. The surface rim has an rim edge and a lateral wall. The rotation bracket includes a bracket body and two arms. Each arm has an arm bottom and a arm top. The rotation bracket is attached to the lateral wall. The bowl housing has a bowl edge. The bowl edge defines a light opening. The arm tops of the two arms are attached to the bowl edge. The bowl housing is rotatable with a tilt angle with respect to the arm tops. The light source is mounted inside the bowl housing for emitting a light from the light opening.

A downlight apparatus includes a driver box, a light source, a light housing, multiple leaf springs, multiple shaft connectors and multiple pads. The light housing has a light holder and a rim. The light holder has a holder plate and a holder wall defining a holder cavity. The multiple leaf springs are placed between the driver box and the light holder. Each pad has a pad hole and a pad scraper surrounding the pad hole. The pad scraper has a protruding part engaging an electric insulation layer on a top side of the holder plate. The shaft connector sequentially passes through a spring hole of the leaf spring, the pad hole and the top plate of the light holder. The protruding part of the pad scraper scraps a portion of the electric insulation layer of the holder plate for connecting the holder plate to ground.

A downlight apparatus includes a light source, a light holder, a driver box, a fixing bracket and two torsion springs. The light holder is used for placing the light source. The light holder has a first side defining a light opening. The driver box is placed on a second side of the light holder. The driver box contains a driver for converting an external power to a driving current supplied to the light source to emit a light from the light opening. The fixing bracket is coupled to the light holder for fixing to an installation cavity. The fixing bracket has a bottom plate and two connector plate. The bottom plate is fixed to the second side of the light holder. The two connector plates are disposed vertically to the bottom plate. Each connector plate has two side units. Each torsion spring has an elastic center and two arms.

A downlight apparatus includes a light source, a driver box, a light housing and a heat dissipation plate. The driver box is used for storing a driver. The driver is connected to an external power source to generate a driving current to the light source. The light housing has a light holder and a rim. The light source is stored in the light holder. The rim defines a light opening for a light of the light source to escape. The heat dissipation plate is placed between the light holder and the driver box for carrying away both heat of the driver box and the light source. The heat dissipation plate is a separate metal piece from the driver box and the light housing. The heat dissipation plate has a portion not covered by the light holder and the driver box and exposed to air.

An integrated ceiling and light system that incorporates a light module into a ceiling tile. The system may include an acoustic ceiling tile and a light module magnetically coupled to the acoustic ceiling tile.

An electrical light fixture wall box (5) having a open top (6) for mounting a light fixture and a bottom (7) with attached leg section (16) having a plurality of legs (8) with teeth (9) for insertion into a wall cutout with screws (10) to adjust and level the wall box in a fully recessed position in a wall.

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 light includes a body, a front housing secured to a front end of the body, a translating retainer rotatably engaged with the front housing, a slip ring positioned around the front housing and between the translating member and the front end of the body, a compressible ring positioned around the front housing and between the slip ring and the front end of the body, a lens mounted to the front housing, an electronic assembly, and a light emitting element in electrical communication with the electronic assembly and positioned within the lens. Rotation of the translating retainer in a first direction causes the translating retainer to drive the slip ring toward the front end of the body, compressing the compressible ring and causing the compressible ring to bulge outward to contact, and removably engage, an inner wall of a pipe or conduit that the light is positioned in.
