철도차량 분야에 전력 절감을 위하여 비싼 초기설치비용에도 불구하고 기존 형광등을 대체하여 LED 등구류의 적용이 늘어나고 있다. LED등구류는 기존 형광등과 달리 점등회로가 필요 없고 제어회로를 통한 전기 공급만으로 점등이 가능하다는 점을 활용하여 철도차량용 LED조명 집중제어장치를 설계기법을 제안한다. 제어장치의 새로운 설계기법은 산업기술연구회의 중소기업지원사업을 통하여 개발하였다. 본 논문에서는 개발한 LED조명 집중제어장치가 철도차량 조명의 요구사항을 만족하고 성능시험을 통하여 성능이 확보되었음을 확인하고 LED집중제어장치를 사용하여 개발 목적인 전력을 절감할 수 있음을 보이고 철도차량에 적용할 경우의 장단점을 분석하였다.
Despite the expansive initial installation cost, the application of LED lights are increasing to replace fluorescent light previously used in order to reduce the power for railway vehicles. With the fact that LED lights do not require lighting circuits and the lighting itself is available only with power supply through control circuits, we are proposing a design method for concentrated control system for railway vehicle LED lights. The new design method has been developed through the small business support project of Korea Research Council for Industrial Science & Technology. With this paper, we are going to verify if the newly developed LED light control system satisfies the requirement for railway vehicle lights and if the appropriate level of performance was acquired through performance tests. Then we shall prove we could reduce the power conforming to the development purpose by using LED concentrated control system and analyze pros and cons when the system was applied to railway vehicles.
