Abstract

발광면을 갖는 조명장치는 투명 또는 반투명수지에 의해 형성된 도광판(11)과 그 도광판(11)내에 그 측면으로부터 광을 조사하기 위한 광원장치(12)를 구비하고 있고 상기한 광원장치(12)는 이것을 상기한 도광판(11)의 측면으로 향해서 이동시키므로서 자동으로 걸어맞추어지는 걸어맞춤수단(15)에 의해 상기한 도광판(11)의 측면에 부착된다.
걸어맞춤용돌기부(15)와 후크(14)는 광원장치(12)가 도광판(11)에 걸아맞추어진 상태에서는 광원장치(12)가 상기한 도광판(11)으로부터 벗겨지거나 수직방향으로 이동하는 것을 방해하도록 형성된 발광면을 갖는 조명 장치이다.
