Abstract

A light emitting sign apparatus using an optical fiber includes: a front panel including a plurality of emission holes; a plurality of optical fibers having one ends respectively connected to the plurality of emission holes and the other ends constituting a concentrated bundle; and a light source assembly including a plurality of light emitting diodes optically coupled to the other ends of the plurality of optical fibers, wherein the plurality of light emitting diodes are located on a plane. Each of the plurality of light emitting diodes belongs to any one of a plurality of groups, one ends of the plurality of groups are connected to the same node, and different power voltages are applied to the other ends of the plurality of groups.
