Abstract

　反射光による電極温度上昇を抑制することできる反射面を有する反射鏡等を提供する。 　ランプから出射された光を電極側に向けて反射させる反射面は、各電極の共通する軸心をＺ軸、電極間の中点（Ｃ）を通りＺ軸と直交する軸をＹ軸とし、共通する軸心上の一点から出射された後に反射面の任意の反射点で反射された反射光がＺ軸と交差する交差位置をＺ座標、当該位置における照度をＹ座標としたＺ－Ｙ直交座標系において、電極間であって共通する軸心上の第１、第２、第３のこの順で並ぶ３点から出射され、反射面上の任意の同一の反射点で反射された３本の反射光についてのそれぞれの照度と交差位置とを座標系上の点Ｐ１（Ｚ１、Ｙ１）、Ｐ２（Ｚ２、Ｙ２）、Ｐ３（Ｚ３、Ｙ３）とした場合に、この３点とＺ軸とで囲まれた領域における一対の電極間に対応する領域部分の面積Ｓｐが広くなるように補正されている。
