Abstract

1,120,378. Control systems for gas discharge lamps. GENERAL ELECTRIC CO. 5 Dec., 1966 [4 Jan., 1966], No. 54282/66. Heading H2H. [Also in Division G3] A load 1, e.g. a gas discharge lamp, is supplied from an A.C. source 2 by way of back-to-back thyristors 7, 8 which receive firing pulses from circuitry 23, 33 operating as described in Application No. 18136/66, and also by way of a circuit which provides a high voltage starting pulse when the load is switched on the said circuit comprising a first capacitor 20 connected across the load 1, a step-up autotransformer 62, a further capacitor 60, a resistor 61 and a glow lamp 63 interconnected as shown. The arrangement is such that the capacitor 20 and a series impedance 6 form a resonant circuit producing an intermediate voltage higher than the A.C. supply voltage, and this intermediate voltage is applied across the elements 60-63 which produce at the load repetitive pulses of a voltage substantially higher than the said intermediate voltage for starting the load. The resistor 61 may be omitted from the circuit, and other suitable connecting arrangements for the elements 20, 60, 62 and 63 are described with reference to Figs. 2, 3 and 4 (not shown). The system may include photo-sensitive means responsive to supply voltage variations and ambient light conditions, means including a third capacitor for increasing the starting energy, means including a thermistor for disabling the operation of glow lamp 63 in the event of failure of the load, and means for producing during the load starting interval a load current different from the normal operating current.
