Abstract

La présente invention concerne l'éclairage décoratif, une plaque de diffraction et un panneau indicateur utilisant le phénomène de diffraction. L'invention transforme une source lumineuse unique en des sources lumineuses multiples par la répétition de la réflexion et de l'incidence de la lumière émise depuis la source lumineuse telle que l'éclairage, et provoque la diffraction et l'interférence de la lumière transmise et émise de la source lumineuse multiple. De cette manière, on renforce l'effet de décoration et d'affichage de l'éclairage décoratif, de la plaque de diffraction et du panneau indicateur en utilisant le phénomène de diffraction selon cette invention.
