The present invention relates to a light emitting signboard. The light emitting signboard comprises: a signboard material; a reflection sheet; a socket slot; a plurality of optical fibers; an optical fiber socket; an optical fiber sleeve; a lamp substrate; and a lamp fastener. The optical fibers are hardened after epoxy resin is filled, are in a watertight state, and have a bar shape. The optical fiber socket includes: a small diameter unit which fixes the optical fibers while a part of the inner circumferential surface is elastically transformed; a grade unit which guides the insertion of the small diameter unit; and a large diameter unit which is latched to the rear part of the socket slot. The optical fiber sleeve includes: an inner sleeve into which one end of the optical fibers is inserted; an outer sleeve of which the front end part is combined to the outer circumferential surface of the inner sleeve, and a mounting end of the lamp fastener is formed on the rear end part the inner circumferential surface; and a piece of tape which makes the outer circumferential surfaces of the inner and the outer sleeve watertight. The lamp fastener includes a fixing member which is made up of a contraction tube for tightly fixing the lamp substrate to the mounting end. Therefore, as the optical fiber socket is elastic and has an outer diameter greater than the inner diameter of the socket slot, and a part of the inner circumferential surface holds and fixes the optical fibers through elastic transformation, the optical fibers are firmly fixed; the optical fiber socket is fixed to the socket slot through forcible insertion and elastic transformation without a component such as a latching projection; and assembly, installation, and maintenance of an external case can be easily and safely done. |
