The present invention discloses an arc discharge light source. The arc discharge light source comprises: an alternating current power supply; an alternating current input circuit; a direct current input circuit; a power supply switching circuit connected with the alternating current power supply, the alternating current input circuit and the direct current input circuit; an arcing circuit connected with the alternating current input circuit and the direct current input circuit; a trigger circuit comprising a first arcing trigger circuit, a second arcing trigger circuit, a first transformer anda second transformer, wherein the primary side of the first transformer is connected with the alternating current power supply, the secondary side of the first transformer is connected with the firstarcing trigger circuit and the second arcing trigger circuit, the first arcing trigger circuit and the second arcing trigger circuit are connected with the secondary side of the second transformer, and the primary side of the second transformer is connected with the arcing circuit. The alternating current commercial power output by the alternating current power supply is processed by the triggercircuit, so that the arcing circuit can stably perform arc discharge, and the stability of alternating current arc ignition is further improved.

Description

technical field [0001] The invention relates to the technical field of arc discharge, in particular to an arc discharge light source. Background technique [0002] Arc discharge is a phenomenon in which two electrodes are kept electrically conductive by gaseous charged particles, such as electrons or ions, under a certain voltage. It is the strongest self-sustaining discharge among gas discharges. Arc discharge can excite the sample to generate spectrum. For example, arc discharge mainly emits atomic spectral lines, which is a commonly used excitation light source for emission spectrum analysis. Among them, the oil spectrometer uses arc discharge laser light source. [0003] Arc discharge light sources in the prior art are usually divided into two types: DC arc discharge light sources and AC arc discharge light sources. Obviously, the DC arc discharge light source can only realize DC arc discharge, and the AC arc discharge light source can only realize AC arc discharge. Th...
