Claims (1)
ブ中央の発光空間囲繞部内に一対の電極が対向配
置され、点灯中の水銀の蒸気圧が１０気圧以上で
あるシヨートアーク型超高圧水銀蒸気放電灯にお
いて、 前記一対の電極は、先端に平面部を有する陽極
を上側にして垂直に配置され、該発光空間囲繞部
の陰極側の周面に、赤外光を反射し、それ以外の
光を透過する光干渉膜が形成されたことを特徴と
するシヨートアーク型超高圧水銀蒸気放電灯。[Claims for Utility Model Registration] A short arc type in which a pair of electrodes are arranged facing each other within the light emitting space surrounding the central part of the bulb in which mercury is sealed together with a rare gas for starting, and the vapor pressure of mercury during lighting is 10 atmospheres or more. In the ultra-high pressure mercury vapor discharge lamp, the pair of electrodes are arranged vertically with the anode having a flat portion at the tip facing upward, and reflect infrared light onto the circumferential surface on the cathode side of the light emitting space surrounding portion; A short arc type ultra-high pressure mercury vapor discharge lamp characterized by forming an optical interference film that transmits other light.
