<p>PURPOSE: A dimming control system for saving the energy of an LED streetlight using a power line communication is provided to efficiently control the dimming of an LED lamp by converting power with high efficiency in a dimming control process. CONSTITUTION: A communication relay unit(110) is connected to a power line(10) and transmits and receives a control signal. An LED driving unit(130) is connected to the power line and converts AC into an LED driving current. An LED lighting unit(140) is composed of a plurality of LED modules. A sensor unit(150) senses the movement of a vehicle. A control unit(120) is connected to the communication relay unit, the LED driving unit, the LED lighting unit, and the sensor unit to control each operation.
