Retro reflector including at least one corner and two mutually parallel vertical faces

摘要

A retroreflective article enabling to retroreflect incident light in its incident direction, and the retroreflective article including at least one retroreflective element, the retroreflective element including at least one reflecting corner comprised of a pair of corner reflecting surfaces which meet at dihedral angle of about 90 degrees; and a pair of vertical reflecting surfaces which are formed on both ends of the reflecting corner to be substantially perpendicular to a corner of the reflecting corner with a distance which is smaller than the highest vertical height and which meet at dihedral angle of about 90 degrees for the pair of corner reflecting surfaces. This retroreflective article has higher retroreflective ratio and wider available retroreflective range, and it is designed to be freely changed its main reflecting direction having the highest retroreflective ratio.

主权项

1. A retroreflective device including at least one retroreflective element, the retroreflective element comprising:
at least one corner, the corner being formed by two reflective corner faces substantially perpendicular to each other; and two mutually parallel vertical reflective faces, each vertical reflective face being in direct contact with and substantially perpendicular to the corner faces;wherein a distance between the vertical reflective faces is smaller than a vertical height of the vertical reflective faces,wherein a light beam retro-reflects from the device via the two corner reflective faces and the two vertical reflective faces.
