Abstract
A flash discharge lamp in which a tubular glass bulb is sealed at both ends by a cathode metal cap and an anode metal cap, respectively; a cathode material member is mounted on the top of an intermediate member planted on the bottom of the cathode metal cap; an adhesive is tamped in the gap between each of the metal caps and the outer peripheral surface of the tubular glass bulb; and a discharge is produced between the anode metal cap and the cathode material member.
Claims24
A flash discharge lamp comprising:
- a glass cylinder having an outer surface and having first and second open ends;
- a continuous cathode metal cap, having a disc portion and having a sealing wall extending from said disc portion at an angle thereto, said first open end of said glass cylinder sealed to said continuous cathode metal cap, said disc portion of said continuous cathode metal cap having an inner face and an outer face;
- a continuous anode metal cap, having a disc portion and having a sealing wall extending from said disc portion at an angle thereto, said second open end of said glass cylinder sealed to said continuous anode metal cap, said disc portion of said continuous anode metal cap having an inner face and an outer face;
- an intermediate member, having a free end, extending from said inner face of said disc portion of said continuous cathode metal cap;
- a cathode material member extending from the free end of said intermediate member such that said intermediate member and said cathode material member are positioned inside said glass cylinder;
- and
- an adhesive material filled in the gap between the outer surface of said glass cylinder and the sealing walls of said continuous anode and cathode metal caps,
- wherein a discharge is generated between said continuous anode metal cap and said cathode material member.
