DEVICE FOR FIRING AND SUPPLY OF DISCHARGE LAMPS Russian patent published in 1998 - IPC

FIELD: electrical engineering, applicable in starterless devices for firing of discharge lamps in which DC power is inverted to AC power with the aid of a high-frequency inverter. SUBSTANCE: the device uses series-connected supply-line filter, rectifier, inverter, r.f. transformer without a core and a discharge lamp. The transformer primary is located inside the auxiliary secondary and its coiling diameter is less than the auxiliary secondary coiling diameter. EFFECT: simplified design and procedure of assembly reduced cost of device. 2 dwg
