PROBLEM TO BE SOLVED: To provide a snow melting type LED traffic signal that can effectively prevent accretion of snow and ice or adhesion of snow to a traffic signal due to cold air in winter, and can achieve excellent visibility.SOLUTION: An LED traffic signal comprises: a transparent cover 1; a transparent planar heating element 2 including a pair of or more electrodes on a conductive layer of a conductive substrate; a reflection sheet 3; a transmission mask part 4; and an LED module 5 with a large number of LED bulbs 9 serving as a light source arranged. The LED traffic signal effectively makes the most use of heat generated by the heating element 2 for melting snow as conductive heat, convective heat, and radiation heat.SELECTED DRAWING: Figure 2

    【課題】本発明は冬季の寒気で、交通信号機への着雪・着氷や雪の付着等を有効に抑止し、良好な視認性を得ることができる、融雪型LED交通信号機を提供する。【解決手段】透明カバー1と、導電性基板の導電層に一対以上の電極を備えた透明面状発熱体2と、反射シート3、透過マスク部4と、光源となる多数のLED電球9を配したLEDモジュール5を備えたLED交通信号機において、発熱体2が発した熱を、伝導熱と対流熱、輻射熱とし、融雪のため有効に活用する。【選択図】 図2
