Lighting device (22) for a false ceiling (10) comprising a plurality of T-profiles (14) having respective longitudinal axes (A) and arranged in a square mesh grid (12), in which each T-profile (14) has a lower wall with a width (W) and in which the grid (12) has a center distance (D) between the longitudinal axes (A) of T-profiles (14) parallel and adjacent to one another, in which the lighting device (22) has an elongated parallelepiped shape with a width (W′) comparable to the width (W) of said T-profiles (14), a height (h) of less than 15 mm and a length (D′) comparable to said center distance (D) between the longitudinal axes (A) of T-profiles (14) parallel and adjacent to one another, and in which said lighting device (22) is capable of being fitted directly in contact with the lower wall of a respective T-profile (14).

A retrofit LED system for a lighting system allowing ease of replacement or installation of an LED lighting system in a grid ceiling. An adapter for providing easy installation of an LED lighting system within a room. A driver for operating directly from any standard AC voltage.

A device for mounting a light fixture structure to a ceiling grid. The device includes an anchor structure extending from the light fixture structure, with a pair of arm structures spaced to receive a ceiling grid segment therebetween at an anchor location on the ceiling grid adjacent a lower region of the ceiling grid. The arm structures have respective distal regions configured to be accessible from an upper region of the ceiling grid and a clamp structure configured to traverse laterally relative to the distal regions to couple with the respective distal end regions and thereafter to be transferable between a released position and a locked position. When in the locked position, the ceiling grid segment held between the anchor and clamp structures place the light fixture structure in the mounted position.

An air frame system includes a frame body defining one or more openings and a plurality of air passages along an inner periphery of the one or more openings. The air frame system further includes a light assembly removably coupled to the frame body outside an outer periphery of the one or more openings.

The present disclosures provides a collar for positioning at least partially around a recessed light fitting and between the recessed light fitting and a structural body. The collar comprises a plurality of collar portions each of which are configured to surround a portion of the recessed light fitting.

A flush-mounted box for installation of a light fitting includes a metal housing that includes a plurality of side walls, at least one side wall defining an opening configured to mount a junction box and/or a cable entry, a bottom wall mountable to the plurality of side walls and defining at least one cutout configured to receive a light fitting, and a top wall mounted to the plurality of side walls opposite the bottom wall. The box further includes a rail rotatably attached to the top wall, wherein the rail is longitudinal and one end of the rail is positioned above the at least one recess, and a mounting bracket configured for sliding attachment according to a longitudinal direction of the mounting bracket in the rail.

A linear light fixture assembly for supporting a light fixture in a ceiling structure, comprises a light fixture mounting structure having a pair of opposed boundary regions configured to fit within a designated light fixture receiving region in the ceiling structure, and a plurality of spring elements configured to spaced outwardly from at least one of the boundary regions, each spring element having a mounting region configured to be anchored to the mounting structure and a free end region to extend therefrom and to be laterally outwardly biased in a first position to form a path of contact with a support surface region on the ceiling structure to anchor the structure in the receiving region, each of the spring elements configured to be movable toward the corresponding boundary region in a second position to release the path of contact to release the light fixture from the receiving region.

A bracket system for mounting an electrical box and other components can include a mounting bracket configured to be removably secured to a support bar or a threaded rod. The mounting bracket can include a plurality of spring arms that can be manually moved towards each other to insert locking profiles of the spring arms into one or more mounting openings of the electrical box. Once the locking profiles are inserted, the spring arms can be released so that they spring resiliently apart from each other and secure the locking profiles against removal from mounting openings.

A light troffer assembly has a cover panel. A T-bar frame has a right T-bar parallel to a left T-bar, and with a rear T-bar parallel to a front T-bar. A bracket frame is mounted between the cover panel and the T-bar frame. The bracket frame includes a first mounting bracket mounted above the right T-bar, a second mounting bracket mounted above the left T-bar, and a first mounting rail and a second mounting rail connecting the first mounting bracket to the second mounting bracket. The mounting bracket frame is sandwiched between the cover panel and the T-bar frame. An LED panel has an LED panel power supply, pivot hook latches and pivot pins.

The present disclosure generally relates to lighting assemblies, and more specifically, to a configurable modular lighting assembly for use within a ceiling grid system. The lighting assembly is easy to install and delivers lighting distributions tailored to optimally illuminate the surface ceiling panels as well as floors, walls and work surfaces below. The configurable modular ceiling grid lighting assembly comprises both standard ceiling grid components such as T-Bar, ceiling panels and suspension cables as well as novel linear support elements with integrated or removable optical assemblies and covering elements. When installed the ceiling grid lighting assembly provided further comprises ceiling panels that are held in-line, above, below or tilted relative to the existing ceiling grid plane and as such provide both aesthetically pleasing features and useful lighting distributions. Further embodiments illustrate how both appearance and lighting distributions can be controlled by selectively applying electrical power to individual light source channels.
