Claims

[Claims for Utility Model Registration] (1) A light guide, such as an optical fiber, which has a light leakage part formed on its circumferential surface over almost its entire length to leak a part of the light passing through the inside to the outside; A lighting fixture consisting of light sources arranged opposite each other to introduce light. (2) A light guide such as an optical fiber with a light leakage part formed on its circumferential surface that leaks a part of the light passing through the inside to the outside is provided with a folded part so that both end surfaces of the light guide are aligned almost on the same plane, and the light guide A lighting device in which the portions between the both end surfaces of the light guide and the folded portion are so close that they can be considered to be almost integral, and a single light source that introduces light into the light guide is arranged opposite to the both end surfaces of the light guide. . (3) The lighting device according to claim 2, wherein the light leakage portion is formed over substantially the entire length of the light guide from one end surface to the folded portion. (4) The lighting device according to claim 1 or 2, wherein the light leakage portion is formed over substantially the entire length of the light guide, and the light leakage rate of each part of the light guide is made different.
