Patent ID: 8486213

Claim:
A method of making a composite light diffusing panel, the method comprising the steps of: providing at least two spaced apart lites; providing a spacer to maintain a gap therebetween; providing a light transmissive fabric to be adhered to an inner surface of at least one light; sizing the fabric such that it is small enough prevent interference with the spacer thereby avoiding wrinkling, and large enough to prevent presence of a gap between the spacer and the fabric; applying a light transmissive adhesive to said layer of fabric or to said inner surface at a density of about 0.5 g/sq.ft and 2 g/sq.ft so that the fabric layer is unsaturated with adhesive to prevent loss of light diffusion properties; adhering the light transmissive fabric layer to only an inner surface of one of said spaced apart lites; curing said adhesive to bond said fabric to said at least one lite; and assembling said lites to form said light diffusing panel.
