内部に、ハロゲン物質が封入され、かつ先端部に突起部がハロゲンサイクル作用によって形成されているタングステン製の一対の電極が配置されている発光管を有し、前記電極の先端部は削り出し加工により略錐体状に形成されたものである高圧水銀放電ランプに対して交流電流を供給して点灯させる点灯回路を備え、
前記点灯回路は、連続点灯中において、前記交流電流の周波数を、前記高圧水銀放電ランプの点灯経過時間とともに変化する動作データに依存することなく２つ以上の異なる値に複数回切り替えて変化させ、変化させる最大の周波数が、３００Ｈｚ〜５００Ｈｚであって、かつ最小の周波数の３倍以上であることを特徴とする高圧放電ランプ点灯装置。 Inside, it has an arc tube in which a pair of tungsten electrodes, in which a halogen substance is enclosed and a protrusion is formed by a halogen cycle action at the tip, is disposed, and the tip of the electrode is machined comprising a lighting circuit for lighting by supplying an alternating current to der Ru high pressure mercury discharge lamp which is formed in Ryakukiri-like manner,
The lighting circuit is configured to change the frequency of the alternating current multiple times to two or more different values without depending on operation data that changes with the lighting elapsed time of the high-pressure mercury discharge lamp during continuous lighting, A high-pressure discharge lamp lighting device characterized in that the maximum frequency to be changed is 300 Hz to 500 Hz and is at least three times the minimum frequency .
