An integrated ceiling and light system that incorporates a light module into a ceiling tile. The system may include a grid support system suspended from an overhead support structure that includes at least one grid support element and first and second ceiling tiles supported by the grid support element in an adjacent manner. A nesting cavity may be formed into the first and second ceiling tiles such that a light module may be disposed within the nesting cavity and coupled to the first and second ceiling tiles. The ceiling tiles may be of the type that conceals the grid support element on which it is supported. In one alternative embodiment, the light module and a nesting region of the ceiling tile may include corresponding edge profiles to facilitate mating therebetween to enable coupling of the light source to the ceiling tile.

Integrated ceiling and light system

The invention is a method for manufacturing a surface covering product having a gloss controlled surface wearlayer coating and a curable composition used in that method. The preferred curable composition is a polymerizable coating which includes a di-isocyanate and/or isocyanurate structure, a polyester polyol, a hydroxy and acrylyl functional polyester, mono, di, or tri-functional acrylates, and a flatting agent and/or hard particulates. The preferred surface covering product is a floor covering product produced as a vinyl film that is precoated with preferably a wearlayer coating that is adhered to the vinyl film, and the surface of the film is preferably embossed. A gloss controlled surface coating is achieved by application of the preferred composition to the printed sheet of film, and the composition is then exposed to low intensity ultraviolet light followed by exposure to ionizing radiation from a low accelerating energy electron beam, which forms an abrasion resistant wearlayer with non-visible degradation of the printed film.
