ASSEMBLED LIGHT-GUIDING MODULE WITH LIGHT-GUIDING FUNCTION OF HIGH EFFICIENCY

摘要

PROBLEM TO BE SOLVED: To provide an assembled light-guiding module with light-guiding of high efficiency.;SOLUTION: An assembled light-guiding module with light-guiding of high efficiency is composed of a plurality of light-guiding structures. Each light-guiding structure includes a light-guiding body unit 1a and a light-reflecting microstructure unit 2a. The light-guiding body unit has a light-guiding portion 10a, at least one concave light-entering portion 11a formed on one end of the light-guiding portion, and a housing portion 12a formed on a plane surface of the light-guiding portion. The light-reflecting microstructure unit has a plurality of light-reflecting microstructures disposed in the housing portion. Thereby, the light-guiding structures are assembled to form a light pipe by joining these light-guiding structures mutually, wherein the concave light-entering portions are mated to form a light-entering groove on one end of the light pipe, and the housing portions are mated to form a housing space that is embedded in the light pipe.;COPYRIGHT: (C)2010,JPO&INPIT
