A multifunctional lighting assembly is configured with optical components such as lenses and reflectors mounted within an elongate body that serves as a cross tee within a T-bar grid arrangement. Protrusions of the elongate body are used to position optical components and embodiments provide for the slidable mounting of optical components. Further embodiments provide for the support of ceiling panels within a suspended ceiling system, connection to a structural ceiling, and inclusion of further components such as sensors, electronic controllers, and wireless modules.

A method for installation of ceiling tiles in an improved mounting hook assembly to form a concealed grid system, the mounting hook assembly being attachable to a mounting stud (1) having recess on top portion to accommodate screws and fixed at the back of each tiles. The method includes attaching the mounting hook assembly to the tile; rotating a load bearing lever member; rotating a positioning lever member to position the load bearing member on a flange of a T grid bar; and fixing the tile below the T grid at a distance that is greater than the thickness of the tile so that when the tile is lifted up, the load bearing lever are returned to a position above the flange level of the T grid and any tile can be removed or installed in totally concealed grid system without dislocating tiles already laid.

A suspended ceiling system for a building structure includes a plurality of parallel struts for supporting a plurality of parallel vanes suspended from the struts in perpendicular relationship thereto. The vanes can be suspended in downwardly spaced relationship to the struts or in contiguous relationship therewith and occur in different forms including illuminated vanes, adjustable vanes and the like.

A system for mounting plurality of panels includes a carrier part for receiving and supporting the panels at intervals along the length, and a locking strip. The carrier part and the locking strip can be mounted to each other to couple the locking strip relative to the carrier part in a locked position with an elongate edge of the locking strip engaging with the panels.

The invention relates to a connecting element for connecting two aligned C-shaped profile rails (12). The connecting in element (10) is in the form of a sheet metal profile the cross-section of which, adapted to the profile rails (12) to be connected, is such that said sheet-metal profile can be slid into said profile rails (12) from the fronts thereof in a captive manner. A handling tab (14) that is accessible after the connecting element has been slid into a profile rail (12) is moulded onto or mounted on said connecting element.

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.

A building panel for a wall or ceiling is provided. The panel comprises a first plate forming a front of the panel, a second plate forming a rear of the panel, and a core structure positioned between the first plate and the second plate and being adhesively bonded to the first plate and the second plate. The panel further comprises an attachment member for attaching the panel to a wall or ceiling or to a structure attached to a wall or ceiling, and a mechanical fastening device which extends between and mechanically fastens the first plate to the second plate and/or the attachment member.

A suspended ceiling system for a building structure includes a plurality of parallel struts for supporting a plurality of parallel vanes suspended from the struts in perpendicular relationship thereto. The vanes can be suspended in downwardly spaced relationship to the struts or in contiguous relationship therewith and occur in different forms including illuminated vanes, adjustable vanes and the like.

A building panel system is provided that includes a perimeter frame; a main beam attached to the perimeter frame; a carrier attached to the main beam, the carrier having a plurality of identical hook members, each of the hook members having a protruding hooking portion on only a first side of the hook member, and a non-hooking portion on a second side of the hook member, the second side being opposite the first side; and a plurality of panels removably attached to the carrier, each of the panels being attached to the carrier by engaging one of the hooking portions.

A dynamic environmentally actuated ceiling baffle and system that incorporates sidewalls with cuts or kerfs, top and bottom portions and sensors to automatically, programmatically and manually properly configure the ceiling baffle for optimal noise reduction based on the environment or the needs of the user, and that can be quickly and easily installed onto ceiling structures using integrated locks, cables or magnets, to produce a dynamic environmentally actuated ceiling baffle system, and to provide an aesthetically pleasing image, along with a reduction in unwanted noise and/or room acoustics, using the programmed or manual actuation to tune the ceiling baffle to respond appropriately to the acoustic need.
