PROBLEM TO BE SOLVED: To previously prevent an excessive abnormal discharge phenomenon by using at least two or more L/C resonance voltage boosting linkage transformers on the output side of a feeder, boosting a corrected sine wave to desired voltage, and impressing it on a neon tube. SOLUTION: Series resonance is performed by a coil L1 of series resonance coils 5a to 5n and a resonance capacitor C, and parallel resonance is performed by a primary winding coil L2 of high frequency linkage transformers 7a to 7n and the capacitor C. Rectangular wave voltage of 25kHz is outputted in an L impedance by converting an impedance in a push-pull electric power transformer 2. This output is matched in an impedance with an electric transmission feeder 4, and is extended up to the periphery of a neon tube, and is corrected to a strainless sine wave by using the series resonance of L1/C and the parallel resonance of L2/C. Voltage is boosted by a transformer 7 using the L2/C as primary winding, and high voltage of a corrected sine wave of 6kV is obtained. This voltage is impressed on the neon tube, and reasonable lighting is performed. |
