This invention provides an arc light unit, comprising a control circuit, a photoelectric conversion circuit, and a potential adjustment circuit. The key feature is the inclusion of a potential comparison circuit. This potential comparison circuit obtains an adjustable potential threshold from the potential adjustment circuit. It also obtains the arc light signal potential from the photoelectric conversion circuit, with each photoelectric conversion circuit corresponding to a potential adjustment circuit. When the arc light signal potential does not meet a comparison condition, the potential comparison circuit sends a suppression signal to the control circuit. When the arc light signal potential meets the comparison condition, the potential comparison circuit sends an arc light signal to the control circuit. The comparison condition is that the arc light signal potential obtained by the potential comparison circuit from the photoelectric conversion circuit is greater than the adjustable potential threshold. The arc light unit provided by this invention sends an arc light signal to the control circuit by determining whether the arc light signal potential meets the comparison condition. This arc light unit can be used to adjust the photosensitivity.
