GAS-DISCHARGE LAMP Russian patent published in 2006 - IPC H01J61/73

Abstract RU 2278442 C1

FIELD: electrical engineering.

SUBSTANCE: proposed high-pressure gas-discharge lighting lamp whose life is extended due to provision for preventing accelerated evaporation of activator has burner made of optically transparent material and electrodes provided with high-melting rod carrying sintered mass. The latter is shaped in the form of cylinder with rounded-off ribs between its side surface and base, rounding radius r_rmeeting following condition: where r₀ is cathode spot radius.

EFFECT: enhanced service life of lamp, improved design of its electrode.
