Abstract
【解決手段】無電極蛍光ランプはランプ部1とパワーカップラ部10とで構成される。ランプ部1はバルブ2を有し、バルブ2の底には内部に落ち窪んだ円筒形の凹部(キャビティ)4が封着され、キャビティ4の底にバルブ2内の放電空間と連通した管状部(排気管)5が溶着されている。排気管5内にはアマルガムを収納した金属容器7が収納される。金属容器7を排気管5内にて誘導コイル13の内側に滞在させて金属容器7と放電空間との距離を近付けているため、放電空間内で放電が生じている状態(無電極蛍光ランプの点灯状態)においてはアマルガムが液相又は液相と固相が混在する状態となり、アマルガム表面の水銀量を放電空間への供給に十分な量だけ維持することができる。
