Abstract

1,130,640. Supply systems for gas discharge lamps. GENERAL ELECTRIC CO. 9 Dec., 1966 [13 Jan., 1966], No. 55165/66. Addition to 1,120,378. Heading H2H. A circuit of the type described in Specification 1,120,378 for supplying a load 1 such as a gas discharge lamp is modified by the provision of a further resistor 17 which is connected between the load side of the thyristors 7, 8 and the junction of the capacitor 11 and resistor 10 in the firing control circuit. It is stated that the further resistor provides for stable load starting and correct voltage build-up during changes in the load impedance. As shown, the arrangement also includes a photo-sensitive circuit 61, 62, 63, 41 to compensate for supply voltage variations, a circuit 20, 21, 6 for producing highvoltage starting pulses, and a circuit with a photoconductor 40 operating to turn the load 1, if a lamp, on and off in accordance with ambient light conditions; modified forms of these circuits are described with reference to Fig. 2 (not shown). The thyristors 7, 8 may be replaced by a single triac (Figs. 3, 3a, not shown).
