Abstract
A LED traffic signal light includes: a rear cover having a heat-dissipating device integrally formed on the rear cover, a front transparent cover combined with the rear cover for encasing a LED printed-circuit-board (PCB) and a power supply circuit device in the front and rear covers, and a plurality of packing rings respectively packed in between the front and rear covers for water proof purpose, whereby upon lighting of the LEDs in the traffic signal light, the heat as produced by the LEDs and power supply circuit will be dissipated outwardly effectively by the heat-dissipating device as formed on the rear cover for prolonging the service life of the traffic signal light.
