Abstract

본 발명은 여러 뷰잉 평면에서 광범위한 역반사 유향각을 타나내는 향상된 큐브-코너 역반사 물품을 제공한다. 본 발명은 큐브-코너의 높이로 측정함에 있어서 축소된 크기를 갖고, 이로써 소정의 유향각을 구하기 위해 요구되는 기울기의 정도를 감소시킨다. 또한, 유향각은 경각상수를 그대로 두고 큐브-코너의 크기를 감소시킴으로써 향상될 수 있다.

Description

향상된 유향각을 갖는 역반사 물질
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 역반사 물품에 사용되는 큐브-코너 역반사 소자를 보여주는 사시도이다. 제2A,2B,2C도는 제1도에 도시된 큐브-코너소자의 측면부에서의 측면도이다. 제3도는 제1도 제2도에 도시된 바와같이 밀집 배열의 큐브-코너 소자를 갖는 본 발명의 역반사 시팅(retroreflective sheeting)의 평면도이다. 제4A 및 4B도는 제3도의 라인 4A-4B를 따라 취한 것으로 본 발명의 역반사 소장에서 두개의 대표적인 부합된 큐브-코너 소자쌍을 보여주는 단면도이다.
