Abstract

　発光素子３２は、内部に赤色光源３８ｒ、緑色光源３８ｇおよび青色光源３８ｂを一列に配列し、その表面側に導光プレート４０を配置している。この長尺物の発光素子３２は、その長手方向においてはほぼ連続するように配列されており、幅方向では大きな間隔をあけて配列されている。導光プレート４０の表面には円錐状の凹部４１が密に形成され、導光プレートの裏面（光源側）には断面三角形状の凸部４２が密に形成されている。導光プレート４０は各光源３８ｒ、３８ｇ、３８ｂから出射された赤色光、緑色光及び青色光を閉じ込めて混色すると共に幅方向に光を広げて出射し、導光プレート４０に比べて大面積の領域を均一に照明することができる。
