<p>PROBLEM TO BE SOLVED: To provide a light-emission device for visual recognition which enables the light emitted by a light-emission diode to enter an optical fiber effectively.SOLUTION: A guidance light-emission device 1 includes a light-emission diode 3, and an optical fiber 4 that is installed adjacent to the light-emission diode 3, and takes in the light emitted by the light-emission diode 3 from an edge face 13 and ejects it from an outer peripheral face. In the guidance light-emission device 1, a plane lens 9 of the light-emission diode 3 and an outer peripheral face near the edge face 13 of the optical fiber 4 are covered with a liner 5 that can reflect the light entering the inner face.</p> |
