A lighting system for a ceiling grid system may provide lighting at a location below the ceiling grid system. The light fixture includes a light source and a support member, and the light fixture may provide diffusely reflected light to a ceiling grid opening. The light fixture may include a wall assembly that is adapted to be moved between a folded configuration and an unfolded configuration.

A light fixture controls lighting distributions with one or more electrically addressable LED boards and a primary optical element which can be back-lit or edge-lit. The light fixture body is configurable, comprising a 3-dimensional housing body with ends that can be cut at a configured angles to create geometric patterns within a ceiling grid installation. The housing body comprises features to retain and align LED boards and the primary optical element. Edge-lit configurations can enable the lighting assembly height to be less than the height of a ceiling grid T-bar. In some embodiments the lighting assembly can also provide structural support within an installed panel system and replace one or more T-bars. The light fixture can be configured to provide low-glare or wide spread batwing ambient light or more directional wall wash, task and accent lighting.

The present invention relates to a false ceiling mounting system that is simple and effective, while also allowing quick disassembly for inspection or total removal. To this end, a section bar with resilient tabs is provided, the false ceiling panel being fit between two section bars.

A ceiling system having a perimeter frame; a grid configured to support a plurality of substrates; and a plurality of bracket assemblies coupling the grid to the perimeter frame, the plurality of bracket assemblies adjustable between a plurality of states in which the grid is supported at a different height relative to the perimeter frame in each of the plurality of states.

A light fixture with edgelit optical element is configured with an elongate body which retains and aligns optical components in a shallow linear form factor. Embodiments can be installed within a ceiling grid system and provide a fixture height less than that of a ceiling grid T-bar. An edglit optical element with light scattering features produces an extended emitting area for low glare and provides light distributions such as asymmetric and symmetric batwing distributions particularly useful in downlighting and other lighting applications.

Covering comprising a structure formed by a plurality of panels provided on their lower face with at least one guide formed by a groove giving access to a cavity and longitudinal profiles perpendicular to said grooves on the panels, said profiles having, in turn, a guide and clips housed simultaneously in the cavities of both guides of the panel and the profile, the clips having a resilient body that is housed, in the expanded position, in the corresponding cavity, said body comprising at least two legs, each leg having, in turn, a shoulder area intended to make contact with the wall of the cavity immediately adjacent to the groove.

A system and method for creating a trompe-l'oeil skylight in a ceiling where a light emitting image of the sky is provided in a structure configured to emulate a skylight frame, including an embodiment of a unified non-rectangular sky image area in a substantially rectangular fixture which mount as a single unit into a substantially rectangular hole in a ceiling.

A ceiling system having a perimeter frame; a grid configured to support a plurality of substrates; and a plurality of bracket assemblies coupling the grid to the perimeter frame, the plurality of bracket assemblies adjustable between a plurality of states in which the grid is supported at a different height relative to the perimeter frame in each of the plurality of states.

The invention provides suspended or dropped ceiling systems based upon the use of standard inverted T-bar lattices. The ceiling panels are constructed from two pieces which, when assembled in place, capture the T-bar in a manner that prevents the panels from shaking loose. A suspended ceiling assembled with the panels of this invention will withstand the forces of an earthquake without experiencing panel drop-outs, and the ceiling will remain intact so long as the T-bars remain suspended from the structural ceiling above. The panels of the invention can, in preferred embodiments, carry lighting fixtures, and the required wiring can be installed and concealed below the T-bars rather than within the plenum space.
