PROBLEM TO BE SOLVED: To provide a self-emission type road sign capable of visually recognizing light radiated from an illuminant with high luminance even when there is no driver for an automobile, pedestrian or the like on a front. SOLUTION: The self-emission type road sign has a case 1, a solar cell 2 housed in the case 1, a battery 3 charged by the solar cell 2, an illuminant radiating light, a control circuit for supplying the illuminant 4 with power, using the battery 3 as a power supply and a windshield 5 covering these equipments. The road sign has a light-transmitting film 6 diffusing light to the extending section of light radiated from the illuminant 4 and controlling a diffusion angle (the diffusion direction) at that time. |
