The present invention relates to an optical fiber signboard, which is capable of securing a sufficient amount of light having visibility and identification even with low energy while minimizing the number of light sources and optical fibers, and is capable of selectively changing display information depending on a traffic environment and a time zone when providing a speed limit in a children protection zone or the like. More specifically, the present invention comprises: a main body which forms an exterior appearance of a signboard and has a plurality of through holes formed in a light emitting portion of a front part to display selected display information; a light emitting unit including one or more LED light sources and provided inside the main body; a plurality of optical fibers which are exposed to the outside as one end is connected to the light emitting unit and light emitting terminals provided at the other end are inserted and fixed to the through holes of the main body such that light flowing in through the one end is emitted, wherein ends of the light emitting terminals, exposed to the outside, are thermally treated so that a diameter of a cross section expands; and a connection holder which has an accommodation space formed therein so that one end of an optical fiber bundle consisting of the plurality of optical fibers is accommodated in one side, and the LED light sources of the light emitting unit are accommodated in the other side, wherein a convex diffusion lens is mounted between the optical fiber bundle and the LED light sources in the accommodation space.

    본 발명은 광원 및 광섬유의 수를 최소화하면서 적은 에너지로도 시인성 및 식별성을 갖는 충분한 광량을 확보할 수 있으며, 어린이 보호 구역 등에서 제한 속도를 안내하는 경우 교통 환경 및 시간대에 따라 표시정보를 선택적으로 가변시킬 수 있는 광섬유 표지판에 관한 것으로, 보다 상세하게는 표지판의 외형을 이루며 전면부 중 발광부위에 복수의 관통홀이 형성되어 선택된 표시정보를 나타내는 본체; 하나 이상의 LED 광원을 포함하고 상기 본체의 내부에 구비되는 발광부; 일단이 상기 발광부에 연결되고, 타단에 마련되는 광방출단이 상기 본체의 관통홀에 삽입 및 고정되면서 외부에 노출되어 일단을 통해 유입된 빛이 방출되며, 외부로 노출되는 상기 광방출단의 끝단이 열처리되어 단면의 직경이 확장되는 복수의 광섬유; 및 내부에 수용공간이 마련되어 일측에 복수의 광섬유로 이루어진 광섬유 다발의 일단이 수용되고 타측에 상기 발광부의 LED 광원이 수용되며, 상기 수용공간에서 상기 광섬유 다발과 상기 LED 광원 사이에 볼록형의 확산렌즈가 장착되는 연결홀더;를 포함하는 것이 특징이다.
