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
