Abstract

A high-luminous-pattern display apparatus includes a surface luminous plate which includes a transparent planar plate stood vertically to a horizontal direction. The transparent planar plate has a front surface and an opposite rear surface, the rear surface being a light incident surface on which direct sunlight and in-air diffused light falls. The surface luminous plate further includes a group of transparent planoconvex lenses arranged uniformly in columns and rows and integrally molded with the front surface of the transparent planar plate. The columns and rows of planoconvex lenses define a front surface of the surface luminous plate, and a planar display plate having a pattern is arranged at the front surface of the surface luminous plate.

Claims

1. A high-luminous-pattern display apparatus comprising a surface luminous plate, said surface luminous plate comprising a transparent planar plate stood vertically to a horizontal direction, said transparent planar plate having a front surface and an opposite rear surface, said rear surface being a light incident surface on which direct sunlight and in-air diffused light falls, said surface luminous plate further comprising a group of spaced transparent planoconvex lenses arranged uniformly in spaced columns and rows and integrally molded with said front surface of said transparent planar plate, said rear surface of said transparent planar plate having a planar section in the spaces between the rows and columns of said spaced planoconvex lenses, and reflective prisms integrally molded with said planar section of said rear surface of said transparent planar plate, said columns and rows of planoconvex lenses defining a front surface of the surface luminous plate, and a planar display plate having a pattern and arranged at said front surface of said surface luminous plate.
