Abstract

　ターゲット面と発光素子の配置面との間の厚みが薄くても、ランプイメージを生ずることなく、面内で均一な明るさの光を放射できる面光源素子アレイを提供する。 　前記面光源素子アレイは、面光源素子５が複数配列されており、前記面光源素子は、導光体１と、前記導光体の内部に配設された少なくとも１つの発光素子２と、前記導光体１の底面などに配設された光制御部材４と、前記導光体の側面側などに配設された反射部材３と、を備え、前記発光素子２から出射した光の５割以上が導光体１の内部で全反射する角度で入射し、前記反射部材３は反射により光を導光体１の内部に戻すように設定され、且つ、光制御部材４は、反射光の進行方向を変更させ、導光体の外部へ出射させるように設定されている。
