ABSTRACT:
A neon tube lighting device comprises a resonance circuit, formed by a capacitor and the primary winding of a leakage transformer, which is connected across a DC power supply via a switching element, the ON-OFF operation of which is controlled by the output signal of a signal generator. The output signal provided by the signal generator has a constant frequency substantially equal to the resonance frequency of the resonance circuit. A neon tube is connected to the secondary winding of the leakage transformer.
