Claims (1)
電に重畳してパルス放電させるシマーパルス点灯
方式にて点灯される閃光放電灯において、 低パワー直流放電によつて陰極の直前で形成さ
れる輝点の発光強度分布の最大発光強度の10%
以上の強度の範囲における電流密度が103A/
cm2以上であり、該範囲を輝点の大きさとすると
き、陰極の表面に該輝点の大きさに等しいか、も
しくはやゝ大きな凹部が形成されていることを特
徴とする閃光放電灯。[Scope of Claim for Utility Model Registration] In a flash discharge lamp that has electrodes at both ends and is lit using a simmer pulse lighting method in which a pulse discharge is superimposed on a low power direct current discharge between both electrodes, 10% of the maximum luminous intensity of the luminous intensity distribution of the bright spot formed just before the cathode
The current density in the above intensity range is 10 3 A/
cm 2 or more, and where a concave portion is formed on the surface of the cathode that is equal to or slightly larger than the size of the bright spot, when the range is defined as the size of the bright spot.
