METHOD FOR IMPROVING POWER AND LIGHT CHARACTERISTICS OF GAS-DISCHARGE LAMPS Russian patent published in 2008 - IPC H01J65/00 

FIELD: lighting engineering; high-power and high-frequency gas-discharge lamps.

SUBSTANCE: proposed method is characterized in that gas-discharge lamp is disposed in magnetic field whose direction is perpendicular to discharge current of lamp followed by voltage application across lamp electrodes, excitation of gas discharge, end initiation of discharge current; magnetic field flux density is constant in magnitude and amounts to 90-110 mT or periodically varies between 0 and this value in space along lamp axis; discharge current amounts to more than 0.5 A at its variation frequency over 1 kHz. Additional magnetic field of same flux density as that of mentioned magnetic field can be applied to lamp at angle of 80 to 100 deg. to lamp.

EFFECT: enhanced capacity of luminous flux, lamp power, efficiency of electrical-to-luminous energy conversion, reduced loss of utilized luminous flux.
