Light guide apparatus formed from strip light guides
First Claim
1. A light guide comprising a plurality of strip-like light guide materials each of which has first and second end faces and which are arranged and connected together side by side at respective end portions including said first end faces so that the first end faces form a linearly extending light input face and are bent at respective intermediate portions so that respective the other end portions including said second end faces extend substantially in parallel to the light input face, said the other end portions of the respective strip-like light guide materials being superposed one on another and bundled so that the second end faces form a light output face in a plane substantially perpendicular to the light input face.
