Title: Improvements in and relating to starting and controlling apparatus for electric discharge lamps
IPC: H05B41/232
Filed: 1944-12-29
Abstract: 623,359. Supply systems for space discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 29, 1944, No. 26079. Convention date, Dec. 31, 1943. [Class 38 (iv)] In a system for starting and operating two parallel connected " cold cathode " discharge lamps on leading and lagging currents respectively, one lamp 1, is shunted by a reactor 10 and the other lamp 2 is shunted by a con. denser 11 in series with the aforesaid reactor 10 to obtain starting voltages. The lamps may be fed from supply mains 4, through switch 5, transformer 6 and ballast reactors 7 and 9 respectively, the condenser 8, also in the circuit of lamp 1, producing leading current during operation thereof. On starting, the reactor 10 saturates and produces the starting voltage for lamp 1 by resonance. When lamp 1 starts, the reactor 10 desaturates and a resonant voltage appears across lamp 2 for starting that lamp. The system may operate at substantially unity power factor.
