PURPOSE: A traffic sign is provided to increase visibility and recognition performance of the long distance with a small number of light emitting diodes. CONSTITUTION: A traffic sign is composed of a rear frame(10a), a front frame(10b), a lighting unit(20) and a sign board(30). A mounting groove is formed within the rear frame. The front frame is combined to the rear frame in which an opening is formed. The lighting unit is insertion-installed in the mounting groove of the rear frame. The lighting unit irradiates the light toward the opening of the front frame. The sign board is attached to the front of the front frame. |
