MULTI-DIRECTIONAL CUBE CORNER RETROREFLECTIVE OBJECT |
摘要 |
Provided is a multi-directional cube corner retroreflective object (hereinafter referred to as a retroreflective object) which can improve the incident angle characteristics and the rotation angle characteristics. The multi-directional cube corner retroreflective object has a large number of connected retroreflective element aggregates, in which a triangular pyramid cube corner retroreflective element having an isosceles triangular bottom surface (ABC) and an element vertex (H), share and assemble a bottom surface vertex (C) and an equilateral bottom surface (AC, BC). The outer peripheral shape of the retroreflective element aggregate is a regular polygon and the bottom surfaces of at least two triangular pyramid cube corner retroreflective elements are not parallel to the reference plane including the outer periphery. |
