Abstract
【解決手段】互いに略平行に並設された板状の第1導光部20及び第2導光部30を有する導光体8を備え、第1導光部20及び第2導光部30の夫々は上面に反射面22a、32aを設けた。これにより、光源2から発せられて第1導光部20内に入射した光の一部はそのまま導光部20内を導光されて先端面24から出射して前方に向けて照射され、一部が反射面22aで反射されてその反射光が下面23から出射して下方に位置する第2導光部30の反射面32aに面照射され、その照射光が反射面32aで前方に向けて反射される。その結果、導光部20の先端面24からは高輝度の出射光による線発光が得られ、反射面32aからは輝度ムラの少ない反射光による面発光が得られる。
