Title:
ENVIRONMENTALLY-FRIENDLY ELECTROLESS DYNAMIC TRAFFIC SIGNAL SIGNBOARD
Document Type and Number:
WIPO Patent Application WO/2018/068189
Kind Code:
A1
Abstract:
A dynamic traffic signal signboard, which uses an optical principle to form a dynamic and effective traffic signal sign, and which is composed of a base layer (1), an image stitching layer (2) and a grating layer (3); the base layer (1) provides a frame; the image stitching layer (2) is divided into a plurality of small areas using equidistant parallel lines, and a plurality of traffic sign images are alternately printed on an upper surface; and the grating layer (3) is engraved with compact parallel grooves thereon. Only one image of the image stitching layer (2) may be seen from a certain angle on the grating layer (3) using the optical principle, and a different image may be seen from a different angle, so that a moving driver may see the dynamic traffic signal signs, thereby increasing the degree of alertness. Due to the lack of need for an external power supply, traffic accidents may be reduced on the basis of being environmentally friendly.
