GAS-DISCHARGE RADIATION SOURCE (VERSIONS) Russian patent published in 2010 - IPC H01J61/04 

FIELD: electrical engineering.

SUBSTANCE: in compliance with the first version, HV electrode (HVE) is arranged in bulb inner tube, while grounded perforated electrode (GE) is arranged on bulb outer surface. Said GE incorporates additionally either current conducting element connected with GE and arranged at minimum distance from HVE on the bulb inner tube outer surface or dielectric cylindrical element placed inside bulb discharge gap of appropriate sizes. In compliance with the second version, HV electrode (HVE) is arranged in bulb inner tube, while grounded perforated electrode (GE) is arranged on bulb outer surface. Bulb inner tube additionally incorporates metal tube with running cooling fluid, while space there between is filled with porous material with thermal conductivity exceeding that of HVE. In compliance with third version, HVE is arranged inside bulb inner tube while GE represents a spiral arranged on bulb outer surface. Metal strip is arranged between spiral wire electrode to connect turns thereof.

EFFECT: higher reliability and efficiency.
