The luminaire can also include a mounting bracket mechanism with a recess circumscribing the light module body and a pair of notches on opposite sides. Torsion spring brackets can be shaped to rotate freely in the recess, whereas friction blade brackets are secured in the notches so that the friction blades do not rotate relative to the light module body.

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.

An LED downlighting apparatus includes a housing with a sidewall having a front facing edge and a back facing edge positioned adjacent to a ceiling when the LED downlighting apparatus is installed in an opening of the ceiling. A depth of the sidewall is less than one inch and a thickness of at least a portion of the sidewall is less than three millimeters. An LED board and a lens are coupled to the housing. The lens is disposed with respect to the LED board such that the lens is illuminated from a back side. One or more mechanical couplers snap fit the apparatus to a junction box installed and positioned above the ceiling such that when the apparatus is snap fit to the junction box through the opening of the ceiling, the housing appears to be surface mounted to the ceiling.

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.

An externally mounted vehicle light display is provided. The light display includes a light display body having an external surface and an internal surface. A plurality of magnets are secured to the internal surface of the light display body while a plurality of light string securement means are also secured to the internal surface of the light display body. A removal facilitating knob is secured to the external surface of the light display body. A battery powered light string is carried on the plurality of light string securement means. Another embodiment provides lights adhered in a track running around the exterior of the light display. Another embodiment has a circular frame containing a track for the lights to be adhered in a central position.

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 light housing assembly includes: (1) a junction box unit having a body with a partially-cylindrical sidewall, a closed end, and a circular opening opposite the closed end, and flat inset facets on the sidewall with knock-out holes formed on the flat inset facets; (2) a light emitter housing containing a light source; and (3) an exterior surface fixture, with a reflector, including means for securing the light emitter housing to the junction box unit. Versions of the light housing assembly may include a mounting bracket assembly for mounting the junction box unit to supportive structure.

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 modular recessed light system employs a frame which secures a mounting ring on one side of a ceiling opening and receives a ceiling collar with a circumferential flange on the other side of the ceiling opening. The mounting ring and the ceiling collar are clamped to opposing sides surrounding the ceiling opening. The collar mounts a pair of clamp members which engage slots of a light module which is insertable into the ceiling opening and retained in recessed relationship with the ceiling. The light module may be a down light module or an angularly adjustable light module. In addition, a trim assembly, which may have a square trim with a down light lens, a square trim with an angled lens, a circular trim with a down light lens or a circular flange with an angled lens are also each releasably retained to the housing by magnetic bonding. A mud or plaster ring may also be optionally mounted over the circumferential flange of the ceiling collar and secured to the mounting ring.
