    • PROBLEM TO BE SOLVED: To provide a short arc discharge lamp which emits light with constant illuminance by stable arc discharge without lowering a structure strength at the cathode tip.
      SOLUTION: In the short arc discharge lamp having a cathode 20 and an anode 30 which are disposed opposite to each other at a short distance H between electrodes, two through-holes 26A, 26B penetrating through a cathode tip-side surface 24S are formed at the tapered cathode tip 24 having a cathode tip surface 24T. At this time, the through-holes 26A, 26B are linearly formed so as to pass through an electrode axis E, and made orthogonal to each other at the electrode axis E.

    • 要解决的问题:提供一种短电弧放电灯,其通过稳定的电弧放电发出具有恒定照度的光,而不降低阴极尖端处的结构强度。 解决方案:在具有阴极20和阳极30的短电弧放电灯中,在电极之间的短距离H处彼此相对设置,穿过阴极前端侧表面24S的两个通孔26A,26B 形成在具有阴极尖端表面24T的锥形阴极尖端24处。 此时,通孔26A,26B被线性地形成为通过电极轴线E,并且在电极轴线E处彼此正交。版权所有(C)2010,JPO&INPIT
