The invention discloses a universal gas lamp starting circuit which comprises a gas lamp, a direct current bus, a resonance circuit connected with the direct current bus, a voltage doubling circuit connected with the resonance circuit, a rectification circuit connected with the resonance circuit, a voltage and current sampling circuit connected with the rectification circuit, a high-voltage energizing circuit connected with the direct current bus, and a control circuit used for coordinating the circuits. The high-voltage energizing circuit, the voltage doubling circuit and the rectification circuit send high-voltage pulses, pre-burning voltages and maintaining voltages to the gas lamp respectively, and therefore the gas lamp can be normally lightened and used for illumination. The invention further discloses a realizing method of the starting circuit. According to different gas lamps, only relevant parameters need to be changed, the circuit structure does not need to be changed, and the starting requirement can be met. The normalization design enables the starting circuit design to be simple, development period is shortened, and development cost is lowered.
Description
technical field [0001] The invention relates to a starting circuit, in particular to a gas lamp starting circuit and its realization method, which can meet the starting requirements of various gas lamps only by adjusting circuit parameters. Background technique [0002] In many strong light applications, such as car lights, searchlights, etc., a large number of gas lamps are used. According to the difference in gas type, electrode distance, electrode shape, etc., the characteristics of gas lamps are also different, resulting in different starting characteristics. Corresponding There are also various starting circuits. At present, there is no general starting circuit for gas lamps on the market, which causes repeated design and repeated preparation, resulting in waste of resources. Contents of the invention [0003] The invention aims to solve the problems of narrow applicable range and poor versatility of the existing gas lamp starting circuit, and provides a general-purp...
