Abstract: A method of creating a sculpted decorative ceiling with lighting fixtures in a suspended ceiling grid utilizing ceiling components constructed with structural side elements and a floor, forming a cavity that extends downward three to five inches. Each individual component has a perimeter installation flange enabling it to be installed into a new or existing ceiling grid system cell. The said components esthetic contours and functional structural side elements, as well as the size of the perimeter installation flange create space(s) between installed components, throughout an entire ceiling arrangement of said components or in specific areas of arrangements of said components, for luminesce channel(s) in which may be positioned one or more lighting fixtures, or combinations of lighting fixtures, attached to the room facing surfaces of the cross tee or main runner flanges that comprise the ceiling grid structural assembly.

Abstract: In one aspect, a system is disclosed including a plurality of modules configured for attachment to a mounting surface. A first module includes a panel and a plurality of structural elements extending from an interior surface of the panel. The panel has a decorative major surface disposed opposite the interior surface and comprises a plurality of edges that form a closed shape. At least some of the plurality of structural elements are positioned proximate the plurality of edges. An attachment surface of the plurality of structural elements is positioned opposite the interior surface, and the attachment surface is configured to abut the mounting surface or to abut an attachment surface of another module for attachment thereto. A method of modifying a mounting surface of a room includes attaching a first module to the mounting surface. In another aspect, a method of creating a room partition is disclosed.
