LIGHT STORAGE STRUCTURE, AND ROAD SIGN AND EVACUATION GUIDANCE SIGN USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a light storage structure capable of making a light storage material emit light with high luminance by reflecting and diffusing light emitted from a light storage material rear face with a reflection material and irradiating the light storage material with the light again, which makes the size thereof compact to thereby be easily arranged in a narrow space such as a road surface or wall surface.SOLUTION: A light storage structure comprises: a planar light-emitting body that emits light in a planar manner; a light passage reflection material that is opposite to a rear face on the planar light-emitting body, whose surface functions as a light reflection surface, and that has a light passage hole arranged in a planar manner so as to pass light from the planar light-emitting body; and a planar light storage material that performs light storage by light passing the light passage hole or reflected on the light reflection surface.
