Abstract

엣지라이트형의 조명장치에 있어서, 도광판이 열팽창한 경우에 광원이 눌려지지 않도록 한다. 본 발명의 조명장치에 있어서는, 도광판(2)이 면방향으로 팽창할 수 있도록 슬라이드 가능하게 지지되어 있으며, 상기 도광판(2)의 측방에 배치된 광원(3)도 동일방향으로 이동 가능하게 지지되어 있다. 상기 도광판(2)의 모서리부(2A)와 대향하는 위치에는 도광판 스토퍼부(4b)가 배치되어 있으며, 상기 도광판(2)의 소정 이상의 팽창은 제한되도록 되어 있다. 이에 따라서, 광원(3)이 프레임부재(4)에 눌려지는 사태를 회피할 수 있다.
