Abstract
Gas and/or vapour discharge lamps are ignited and fed in a circuit which has a semiconductor switching device 9 which ceases to conduct when current in it due to discharge of a capacitor 4 across the lamp 5 tends to reverse and which is controlled to conduct again after a time greater than 1/4f where f is the natural frequency of the circuit across the input terminals 1, 2 which includes the capacitor 4. This provides a derived high frequency ignition voltage for a discharge lamp with or without heaters 6, 7. In Fig. 4 an autotransformer 65 has part of its winding in the capacitor circuit to increase the ignition voltage and the control circuit 69 operates on reverse parallel semiconductor rectifiers 311, 321. This control circuit has discs 371, 40 which break down when respective capacitors 361, 391 are charged and make the thyristors 311, 321 conduct. In Fig. 5 (not shown) a single controlled rectifier is connected in the circuit through a rectifier bridge.
