Abstract
【解決手段】直管部22と角管部23とを備える略正方形環状の蛍光ランプ10を用いる。照明器具1は、器具本体41の下側を覆う反射体42を備える。蛍光ランプ10の発光管21は反射体42の略八角錐状の反射面部63に光学的に対向する。発光管21の直管部22は反射体42の主反射面部64に光学的に対向し、発光管21の角管部23は反射体42の角反射面部65に対向する。発光管21の直管部22が照射した光は主反射面部64で反射して四方に向かう。発光管21の角管部23が照射した光は角反射面部65で反射して四隅の方向へ向かう。直管部22と主反射面部64との距離よりも、角管部23と角反射面部65との距離が大きくなるように設定する。
