Abstract: The present invention relates to a ground-embedded pedestrian traffic light and, more specifically, to a ground-embedded pedestrian traffic light capable of reducing the risk of damage and resistance to corrosion by employing a pin combination method in regard to the combination of an upper case (300) and a lower case (300) and the combination of the lower case (300) and a radiation member (100), and preventing permeation of water from the outside by including a gasket in a combination surface of each component, while forming a combination groove to locate the gasket. To achieve the purpose, the present invention includes: a radiation member (100) radiating generated heat; a lower case (300) having a space (310) provided to combine the radiation member (100), and formed with one open side to deliver heat to the combined radiation member (100); a signal substrate (500) located in an upper part of the lower case (300) and including an LED module displaying traffic signal; a first gasket (200(a)) provided along an upper circumference of the lower case (300) so as to prevent water from permeating into the signal substrate (500); and an upper case (600) having a circumference formed along the first gasket (200(a)) to be combined with the lower case (300), and penetrated by the traffic signal.
