Abstract

1,155,264. Supply systems for discharge lamps. PATENT INDUSTRIAL GROUP Ltd. 18 Aug., 1966 [19 May, 1965], No. 21112/65. Heading HQH. [Also in Division H3] A discharge lamp such as a neon tube 12 is supplied from a D.C. source 1 by way of a converter having two transistors and two transformers 3, 10 a bridge 2 of rectifiers being provided so that the D.C. source 1-for example, a battery-can be connected in either polarity. When the D.C. source is switched on, the circuit imbalance will cause one transistor to conduct more than the other. The rise of current in the windings of transformer 3 connected to this transistor will cause it to conduct still more heavily until the transformer 3 saturates after which the current through the transistor decreases whilst the current through the other transistor increases. A diode 5 provides a reverse bias with respect to the input voltage. Thus an A.C. is produced in the secondary winding of the transformer 10. A flashing light may be produced by a time switch connected in the source 1. If the converter operates at 50 c.p.s. the tube 12 may alternatively be supplied from a mains supply.
