description The invention provides an anti-interference demagnetization detection power supply circuit. The anti-interference demagnetization detection power supply circuit comprises a first driving module and a lamp string group composed of a plurality of LED lamp beads connected in series. The high-voltage output end of the first driving module is connected with the positive electrode of the lamp string group, the negative electrode of the lamp string group is connected with the positive electrode of the first semiconductor diode D1, and the negative electrode of the first semiconductor diode D1 is connected with the low-voltage output end of the first driving module and grounded through the decoupling capacitor C. According to the anti-interference demagnetization detection power supply circuit provided by the invention, the isolation diode and the decoupling capacitor are arranged at the output end of the first driving module to achieve the effects of isolating interference signals and filtering high-frequency interf
