Abstract
1,233,841. Control systems for gas discharge lamps. THORN LIGHTING Ltd. 24 April, 1969, No. 21085/69. Heading H2H. [Also in Division H3] A class C transistor oscillator suitable for powering a discharge lamp has a feedback transformer 50 to maintain a tank circuit 18, 20 in oscillation and a winding 32 coupled to the tank circuit to provide a trigger signal. As described, the transformer 50 together with the C.R. circuit 28, 30, effects oscillation in blocking oscillator fashion and the feedback from the tuned circuit stabilizes the frequency. Diodes 44, 56, 62 and 64 protect the base against excessive forward and reverse voltages without adding resistance which would slow down the discharge of stored carriers and diode 60 protects the collector. A resonant choke 58 limits the collector current. A resistor may be connected across diode 44 (Fig. 5, not shown), and two circuits may be connected in push-pull manner to the tank circuit (Fig. 6, not shown).
