Abstract
A light emitting sign apparatus including an optical fiber includes an outer frame. The outer frame includes an accommodation space having an opened front side. A front panel covers the front side of the outer frame, and includes a plurality of first front emission holes. A light source module is located in the accommodation space and includes at least one light source. A plurality of first front optical fibers have first ends connected to the plurality of first front emission holes and second ends optically coupled to the at least one light source. At least one outer illumination sensor is located in the accommodation space. A plurality of outer optical fibers have first ends connected to the outer emission holes provided in the outer frame and second ends optically coupled to the at least one outer illumination sensor.
