Abstract

본 발명은 엘이디를 광원으로 하며, 광이 조사되는 전 지역의 휘도를 높이고 조사지역 내에서의 밝기 편차를 최소화할 수 있는 엘이디 가로등에 관한 것으로, 본 발명에 따른 엘이디 가로등은 지주의 선단에 마련된 케이스와, 상기 케이스의 내부에 마련되고 다수의 엘이디가 상호 이격되게 장착되는 기판과, 상기 기판에 밀착되어 상기 엘이디의 발광으로 발생된 열을 방열시키는 방열부를 포함하며, 상기 다수의 엘이디는 상호 다른 휘도를 갖으며, 상기 기판의 중앙부로부터 상기 기판의 가장자리로 갈수록 점진적으로 휘도가 증가되게 설치되고, 상기 엘이디의 사이에 해당하는 상기 기판의 부위에는 상기 엘이디의 빛을 산란시키는 산란부재가 마련되어 형성된다. 본 발명에 따른 엘이디 가로등은 기판의 볼록 또는 오목한 곡면에 상호 다른 휘도를 갖는 다수의 엘이디를 배열 설치하되, 곡면의 중심부로부터 가장자리로 갈수로 점진적으로 휘도가 증가되게 설치하여, 조사범위를 확장시키면서도 휘도가 감소되는 것을 방지할 수 있는 효과가 있다. 또한 엘이디의 사이에서 엘이디 빛의 일부가 산란부재에 의해 산란되어 조사범위의 휘도를 향상시킬 수 있으며, 휘도가 감소되지 않고 조사범위가 확장되어 인접하는 가로등 사이에 사각지대가 형성되는 것을 방지할 수 있는 효과가 있다. 아울러 동일한 휘도의 엘이디를 장착하더라도 엘이디 사이의 빔각을 중앙부에서 가장자리로 갈수록 점점 좁아지게 형성하므로써 조사범위를 확장시키면서도 휘도가 감소되는 것을 방지할 수 있다.
