LED TRAFFIC LIGHT WITH STRUCTURE FOR RADIANT HEAT

摘要

PURPOSE: An LED traffic light with a structure for radiating heat is provided to efficiently control sudden temperature rise by moving an LED traffic light in rear part. CONSTITUTION: A case(10) comprises a ventilation opening(12) in a rear part. An LED substrate(30) is fixed to the front side of a case and includes a plurality of LED devices. A lens(40) surrounds the front of the LED substrate. . The lens guides light from the LED device. A heat circulation member(60) is functioned as a heat path. Heat is generated between the LED substrate and the lens.
