High-luminous-pattern display apparatus

摘要

The present invention is directed to a high-luminous-pattern display apparatus that is intended to make a pattern distinguishable and readily recognizable even at the night and in the case of back light of the direct sunlight and in air diffused light falling on the back of the pattern. One embodiment is composed of high-luminous elements wherein each of nearly semispherical planoconvex lenses (1) is slanted at a prescribed angle with a horizontal plane to allow in-air diffused light flux (4) in the daytime to be collected on an incident surface and emerge in a horizontal direction from the opposite surface to the incident surface, and a surface luminous body (11) having a prescribed number of said high-luminous elements arranged uniformly in columns and rows. Another embodiment is composed of a transparent planar plate having a group of transparent planoconvex lenses arranged uniformly in columns and rows and integrally molded with the surface opposite to the light incident surface, and a planar display plate arranged in front of said surface luminous plate and containing a pattern. Another embodiment is disclosed wherein a high-luminous reentrant-reflective sheet or a sheetlike EL element plate that becomes luminous by applying a commercial power source or a power source of a solar cell is bonded to the planar section of said surface luminous plate except the transparent planoconvex lens section, or the planar section of said surface luminous plate except transparent planoconvex lenses is integrally molded with said planoconvex lenses as reflective prisms.
