An interconnection structure of a neon lamp for a signboard is provided to maintain a constant brightness on an overall surface of the neon lamp by restricting and compensating currents flowing in respective lamp tubes. An interconnection structure of a neon lamp for a signboard includes an inverter(11) outputting a sinusoidal AC high voltage. Neon lamp tubes are arranged to be apart from each other by a constant distance. Dielectric capacitors(C1-C10) are series-connected to first ends of the neon lamp tube, respectively. The dielectric capacitor adjusts an impedance of the neon lamp tube and restricts and compensates for the current flowing through the neon lamp tube, such that graphitization of the neon lamp tube is prevented. A first electrical wire(12) is connected to an H terminal of the inverter. The first electrical wire is connected to the dielectric capacitors. A second electrical wire(13) is connected to an L terminal of the inverter. A common third electrical wire(14) is connected to second ends of the neon lamp tubes. |
