Abstract
Abstract A shallow profile vaulted lighting module is formed by making a dual module structure in the same space which would normally be occupied by a single module or by using half the area of a normal module to form a small module structure. The small module structures are then provided with lenses so that one or both sides of the vaulted section can function as the luminaire lens for a light.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
215 words
An acoustical suspended ceiling system for use with a room having a main ceiling from which said acoustical ceiling is to be suspended, comprising a plurality of acoustical panels, means to individually and removably support each of the acoustical panels, a plurality of diffuser panels, means to individually and removably support said diffuser panels, said means supporting the acoustical panels and the diffuser panels holding the panels at an angle to a plane passing through the lower portions of the removably supported panels and in a spaced relationship to one another with the distance between the lower portion of each of said removably supported panels being greater than the distance between the upper portions of each of said removably supported panels whereby a downwardly opening space of increasing crosssectional area is defined between said removably supported panels, said supporting means including main runner means extending adjacent said removably supported panels and cross tee members extending between said main runner means and actually supporting said removably supported panels, said removably supported panels defining at least one shallow vaulted structure in which at least one side of each vaulted structure is composed of a diffuser panel, and a light fixture means mounted behind the diffuser panel to provide illumination to the area below the suspended ceiling system.

Claim 3
Dependent Claim
62 words
The acoustical ceiling of claim 1 wherein two adjacent vaulted structures are formed, and the side of each vaulted structure of the adjacent vaults being formed from a diffuser panel and the opposite sides of each vaulted structure being formed of an acoustical ceiling panel whereby the two adjacent diffuser panels form a lens for a lighting fixture overlying the diffuser panels.
Claim 4
Dependent Claim
54 words
The acoustical ceiling system of claim 1 wherein both panels of the vaulted structure are diffuser panels and adjacent each side of this vault is placed acoustical ceiling panels in the plane of the ceiling system so that the total vaulted assembly acts as the lens for the lighting fixture overlying the diffuser panels.
