PROBLEM TO BE SOLVED: To clearly display a figure such as a pedestrian by providing a translucent part and a shading part on the front cover of a traffic signal device, and providing a semitransparent part for scattering light of an emission diode on the boundary line. SOLUTION: A base board 2 arranging the emission diodes 3, 3,... with lenses is attached to the front of the device body 1 of the traffic signal device, and covered by a transparent plastic front cover 4. A block plastic sheet 5 is stuck on the inner face of the front cover 4, the translucent part 6 and the shading part 7 are classified, and the figure such as the pedestrian is displayed on the translucent part 6. Embossing is applied on the boundary line of the translucent part 6 and the shading part 7 of the surface or the rear face of the front cover 4 to provide the semitransparent part 8. Thereby since the light of the emission diodes 3, 3,... is scattered, the figure such as the pedestrian can be clearly displayed even when it is the light source of the emission diodes 3, 3,.... |
