Abstract

PURPOSE: To provide a thin light diffuser for surface illumination capable of displaying a picture and unitizing it, by forming a laminated translucent sheet body having a light reflecting layer formed on a surface facing a light projecting surface, while its one end forms a surface of light incidence and another end forms a step shape. CONSTITUTION: Light from a lamp 3 enters into each translucent sheet body 1 of transparent acrylic resin from one end 1a of an end surface of the light incidence A, and reaches another end 1b or a surface 1c facing it while repeating interface reflection. The light reflected by a reflecting layer 2 comprising metal such as aluminum or white paint on these surfaces is formed into uniform light and is projected from a projecting surface B. A double-sided and lighting system can be obtained as a thin type by placing two units of the light diffuser close to the reflecting layer 2, and a large lighting system can be also compactly structured by placing many of them in series.
