Abstract

LED 광원을 이용한 엣지라이트형의 조명장치에 있어서, 도광판의 열팽창에 관계없이 발광효율을 높게 유지할 수 있도록 하기 위한 것으로서, 도광판(2)의 측방에는 상기 도광판(2)의 측면(2c)의 법선방향(±n)으로 이동할 수 있도록 LED 광원(3)을 배치하고, 상기 LED 광원(3)의 배면측에는 슬라이드부재(7)를 슬라이드 가능하게 배치하고, 상기 슬라이드부재(7)의 배면측으로서 프레임부재(4)의 내부에는 압축된 스프링부재(8)를 배치해 둔다. 이에 따라서, LED 광원(3)은 도광판(2)의 측면(2c)에 항상 가압된 상태가 되므로, 도광판(2)의 열팽창에 관계없이 발광효율을 높게 유지할 수 있다. 또한, 스프링부재(8)는 도시와 같은 간단한 구성이기 때문에, 코일스프링 등을 이용하는 경우에 비하여 컴팩트화가 가능하다.
