Abstract

The invention relates to a power supply of a neon lamp and specifically relates to a neon-lamp power supply which is adjustable in voltage. The power supply for the neon lamp includes an AC power supply, a high-frequency electronic transformer and a rectifying circuit. The AC power supply is connected with the high-frequency electronic transformer. The rectifying circuit is connected to an output end of the high-frequency electronic transformer. An output end of the rectifying circuit is connected with the neon lamp. A voltage adjustment circuit is connected between the rectifying circuit and the high-frequency electronic transformer. After the structure is adopted, the power supply of the neon lamp is capable of adjusting the voltage accurately so that the neon lamp works in a best state.

Description

[0001] technical field [0002] The invention relates to a neon lamp power supply, in particular to a neon lamp power supply with adjustable voltage. Background technique [0003] Neon lights need to apply high voltage to the electrodes at both ends of the tube to make the inert gas in the neon tube glow. Various neon lamp tubes require different voltages to be applied to the electrodes, and the existing neon lamp power supply cannot adjust the output voltage. [0004] An existing electronic power supply for neon lamps includes a high-frequency electronic transformer, and a rectification circuit is added at the connection between the high-frequency electronic transformer and the neon lamp, so that the two ends of the neon lamp are respectively connected to the output ends of the high-frequency electronic transformer through the rectification circuit. This neon electronic power supply also cannot adjust the output voltage. Contents of the invention [0005] ...
