GAS-DISCHARGE LAMP Russian patent published in 2011 - IPC H01J61/18 

FIELD: electricity.

SUBSTANCE: gas-discharge lamp comprises a burner from optically transparent material, containing inert gas, alkaline metal and/or a radiating composition, generating radiation in optical area of spectrum. Source of supply is source of supply of impulse-periodic action, having duty current, I duty, from 0.06 A to 0.15 A, and for capacity of gas-discharge lamp, D_l, W, amplitude of periodic current impulse, I_{a, per}, A, frequency of periodic current impulse, ν, Hz, and time of periodic current impulse passage, Timp., sec, the following ratio is met: where K - coefficient of proportionality with dimension of A/W numerically equal to 1.0.

EFFECT: improved energy efficiency of lamp in optical area of spectrum.
