Abstract: PURPOSE: A traffic signal system capable of controlling and detecting a traffic signal status using power line communication is provided to improve maintenance and management operation by transmitting and receiving a signal using a power line without a dedicated communication line. CONSTITUTION: An LED(Light Emitting Device) module(130) serves as a light source of a traffic signal. A power supply(110) converts AC(Alternating Current) power applied from a traffic signal controller(220) through a power line into DC(Direct Current) power suitable for driving the LED module. A LED module(130) controls luminosity of the LED module by adjusting a DC voltage (or DC current) provided from the power supply. An LED failure detecting unit(140) detects a voltage and/or current of each LED of the LED module to determine the failure of each LED. A power line communication unit(160) communicates with the traffic signal controller using the power line. A data controller(150) calculates a failure rate based on information related to the determination result and forms data in a frame unit to send it to the power line communication unit.
