The present invention relates to a lighting system for a vehicle, performing dimming using a power line. The lighting system for the vehicle, performing the dimming using the power line, according to the present invention comprises: a controllable power transmission unit (100) which receives a DC power from a battery of the vehicle, generates a DC power of which the voltage level is switched according to light control information to be transmitted, and transmits the DC power through a power line; an LED driving circuit (300) which drives an LED module (400) by using the DC power received through the power line; and a dimming information receiving control unit (200) which reads dimming information from a switching pattern of a voltage level in the DC power received through the power line and controls the LED driving circuit (300) according to a reading result. Accordingly, the lighting system does not require wiring of a dimming signal line or installation of a wireless transceiver.

    본 발명에 따른 전원선을 이용한 조광을 수행하는 차량용 조명 시스템은, 차량의 배터리로부터 DC 전력을 입력받으며 전송할 조광 정보에 따라 전압 레벨이 스위칭되는 DC 전력을 생성하여 전원선을 통해 전송하는 컨트롤러블 전력전송부(100); 상기 전원선을 통해 수신되는 DC 전력을 이용하여 LED 모듈(400)을 구동하는 LED 구동 회로(300); 상기 전원선을 통해 수신되는 DC 전력에서의 전압 레벨의 스위칭 패턴으로부터 조광정보를 판독하며, 판독 결과에 따라 상기 LED 구동 회로(300)를 제어하는 조광정보 수신 제어부(200);를 포함하여 구성되는 것을 특징으로 한다.
