Thin sheet-shaped surface light source plate

Abstract

Abstract PURPOSE:To form a thin surface light source by eliminating a sheath material of an optical fiber, forming a minute irregularity on the surface of a core material, illuminating a condensed light beam to a section of its one end or both ends, and arranging plural pieces of thin line light sources which are obtained, on a plane. CONSTITUTION:A sheath material 8 being a skin of an optical fiber 1 is eliminated, and a minute irregularity is formed on the surface of a core material 9. When a condensed light beam is illuminated to a section of its one end or both ends, this processed part shines, and forms a line light source. Subsequently, this line light source is arranged planely in a large number on a smooth plate body 3, it is fixed, the ends of its optical fibers 1 are made up into a bundle, and when a condensed luminous flux 6 is illuminated to a section of one end or both ends of this flux, a light beam is emitted from the surface of many optical fibers 1 which have been arranged planely on the plate material 3, and a surface light source is obtained.
