Disclosed is a traffic signal device. The present invention includes: a printed circuit board wherein LEDs for traffic signals are mounted; a power supply line having one end connected to the printed circuit board to supply operation power of the LED; and a power supply connected to the other end of the power supply line. According to the present invention, since only the power supply in a traffic light product is separately replaced and maintained, it is possible to perform replacement and maintenance work very efficiently and safely, and is also possible to reduce replacement and maintenance costs. In addition, according to the present invention, since it is possible to supply DC power through the power supply, it is possible to eliminate the risk of traffic light failure due to a short circuit caused by a direct supply of conventional AC current, and eliminate accidents due to an electric shock in the event of a disaster such as a typhoon.

    교통 신호 장치가 개시된다. 본 발명은, 교통 신호용 엘이디가 장착된 인쇄 회로 기판, 일단이 인쇄 회로 기판에 연결되어, 엘이디의 동작 전원을 공급하는 전원 공급선, 및 전원 공급선의 타단에 연결되는 전원 공급 장치를 구비한다. 본 발명에 따르면, 신호등 제품에서의 전원 공급 장치만 별도로 교체 및 정비 작업을 하게 됨으로써, 교체 및 정비 작업을 매우 효율적이면서도 안전하게 수행할 수 있게 될 뿐만 아니라, 교체 및 정비 비용 또한 절감할 수 있게 된다. 아울러, 본 발명에 따르면, 전원 공급 장치를 통해 직류 전원을 공급할 수 있게 됨에 따라, 종래의 교류 전류의 직접 공급에 따른 누전으로 인한 신호등 고장, 태풍 등의 재해 발생시의 감전 사고 등의 위험을 제거할 수 있게 된다.
