A ceiling system including: a ceiling structure suspended in an interior space. The ceiling structure includes: a perimeter frame defining a central opening, the perimeter frame comprising a fabric gripping member; a support grid comprising a plurality of intersecting struts defining a plurality of grid openings, the support grid disposed within the central opening and coupled to the perimeter frame; a plurality of acoustic ceiling panels, each of the acoustic ceiling panels mounted to the support grid and disposed in one of the grid openings; and a tensioned fabric sheet having a perimeter portion that is engaged by the fabric gripping member of the perimeter frame, the tensioned fabric sheet located below the acoustic ceiling panels and covering the central opening.

A ceiling panel according to the present invention has opposed translucent membranes secured in a tensioned state across a perimeter frame. The frame includes frame members that are designed to oppose inward bowing of the perimeter frame caused by the tensioned membranes. The frame members have a side profile shaped to conceal a grid support network with the lower translucent member extending across and about a lower edge of the perimeter frame. The invention also includes a modified structure for supporting of translucent panels below a grid network.

A sound-absorption assembly comprises a tubular-shaped body having ends closed respectively by first and second microperforated tensioned flexible sheets and at least one planar diaphragm disposed inside the tubular body between the microperforated flexible sheets so as to delimit two spaces between said sheets.

A light fixture is disclosed. The light fixture includes a frame, a light source disposed within and coupled to the frame, and a lens coupled to the light source. The light also includes a first fabric layer coupled to the frame at a first distance from the lens and a second fabric layer coupled to the frame at a second distance from the lens. The first fabric layer has a plurality of dots printed thereon.

A ceiling suspension system comprises a flexible panel, a first support structure and a plurality of elongate support members, wherein each elongate support member comprises a first end and a second end. The first end of each elongate support member is coupled to the first support structure and the second end of each elongate support member is coupled to the flexible panel. The coupling between the elongate support members and the flexible panel is arranged to force the flexible panel into a desired shape.

Provided herein is a sheet fixing frame, which is installed on a periphery of an installation subject and secures an end of a cover sheet for finishing an installation subject area, the sheet fixing frame including a fixing frame which has a fixing plate contacting the installation subject area, a fixing hook which is bent in one end of the fixing plate and to which an end of the cover sheet is coupled, and a supporting plate which is bent in a direction parallel to the fixing hook in another end of the fixing plate so as to provide a receiving space between the fixing hook and supports the cover sheet, wherein the fixing frame is placed on the periphery of the installation subject area; a fastening member which penetrates the fixing plate between the fixing hook and the supporting plate and is fastened to the installation subject area; and a supporting member which has a coupling to which the supporting plate of the fixing frame is inserted at its one end, and a supporter which supports the cover sheet at its another end.
