Translucent decorative panel forming method for e.g. outer wall of dwelling, involves machining faces of composite product according to symmetric patterns with respect to mean plane of core for constituting light passage zones

摘要

The method involves forming a composite product composed of a core (2) in translucent material e.g. translucent resin, placed between two plates (3, 4) made of opaque material e.g. wood, so that the product has two opaque faces. The faces are machined according to symmetric patterns with respect to a mean plane of the core for constituting light passage zones, where the core has a sheet of light conductive fibers. An outer surface of the fibers is subjected to a treatment for assuring lateral diffusion of light.
