Abstract
A bulb-shaped flashtube is provided with a metal envelope to increase its strength and enhance its reliability and operating characteristics. The metal envelope comprises a hollow cylindrical container including an open bottom end and an inwardly extending annular flange at its top end which defines a window opening in the container. A circular base of insulating material is sealed in the open bottom end of the container. A plurality of conductors extend through the insulating base to support a plurality of electrodes within the container. A circular, transparent window is sealed to the annular flange inside the top end of the container for transmitting a flash of light upon electrical discharge between the electrodes.
Claims20
A gaseous-discharge device of the type comprising a gas-filled envelope which contains spaced electrodes for electrical discharge therebetween to produce a flash of light, wherein said envelope comprises:
- a hollow conductive body having first and second openings;
- an insulating base sealed in said first opening of said conductive body and including means to support the electrodes within said conductive body;
- and
- a transparent window sealed to the inside of said conductive body at and over said second opening for transmitting the flash of light therethrough upon electrical discharge between the electrodes.
A gaseous-discharge device of the type comprising a gas-filled envelope which contains spaced electrodes for electrical discharge therebetween to produce a flash of light, wherein said envelope comprises:
- a hollow cylindrical body of metal including a first open end and a second partially closed end provided with a window opening;
- an insulating base sealed in said open end of said body and including means to support the electrodes within said body;
- and
- a transparent window sealed to the interior of said body at said partially closed end over said window opening for transmitting the flash of light therethrough open electrical discharge between the electrodes.
A gaseous-discharge device of the type comprising a gas-filled envelope which contains an anode and a cathode spaced from the anode for generating a flash of light upon electrical discharge therebetween, wherein said envelope comprises:
- a hollow cylindrical container of conductive material, said container including an open bottom end and an inwardly extending annular flange at its top end which defines a window opening in said container;
- a circular glass base sealed in said open bottom end of said container and including means to support the anode and cathode within said container;
- and
- a circular, transparent glass window sealed to said annular flange inside said top end of said container for transmitting the flash of light therethrough upon electrical discharge between the anode and cathode.
A gaseous-discharge device, comprising:
- an insulating base;
- a plurality of conductors extending through said base;
- a plurality of electrodes mounted on said conductors in a spaced configuration;
- only one envelope sealed to said base to contain said electrodes, said envelope being made of metal and including a window opening;
- and
- a transparent window sealed to the inside of said envelope at and over said opening for transmitting light therethrough upon an electrical discharge between the electrodes.
