PROBLEM TO BE SOLVED: To provide a traffic light with an LED light-emitting surface usable in a snowy district.SOLUTION: An LED light-emitting surface 1 emits light from the whole surface by one color of any of blue, yellow or red, and those colors are replaced in time series. A traffic light includes a plurality of regions where a blink cycle of one color of the LED light emission is mutually different when the LED light-emitting surface 1 emits light from the whole surface by one color. The traffic light provides a plurality of regions in the LED light-emitting surface 1, and can superpose, in each region, arrow signals 6, 7, 8 such as left turn, strait forward, and right turn on the one color whole surface light emission as background at prescribed timing.SELECTED DRAWING: Figure 5 |
