The invention discloses a self-starting ignition circuit of an electromagnetic induction lamp. The self-starting ignition circuit comprises a CPU chip STC12C5616AD, a half-bridge driving circuit U3, a capacitor C1, a capacitor C2, a capacitor C3, a capacitor C4, a resistor R5 and a crystal oscillator CRY1. One end of the capacitor C4 is connected with a 5V power source, the other end of the capacitor C4 is grounded, one end of the capacitor C1 is connected to a +5V power source, the other end of the capacitor C1 is connected with the resistor R5, the other end of the resistor R5 is grounded, one end of the crystal oscillator CRY1 is connected with a pin (4) of the STC12C5616AD, and the other end of the crystal oscillator CRY1 is connected with a pin (5) of the STC12C5616AD. One end of the capacitor C2 is connected with the pin (4) of the STC12C5616AD, the other end of the capacitor C2 is grounded, one end of the capacitor C3 is connected with the pin (5) of the STC12C5616AD, the other end of the capacitor C3 is grounded, and a pin (12) of the STC12C5616AD is connected with a pin (1) of the U3. An IR2184 chip is adopted in the half-bridge driving circuit U3. According to the adaptive optimization starting ignition circuit with a microprocessor as a core, the problem that the electromagnetic induction lamp is started poorly due to the fact that lamp tube parameters of domestic and foreign manufacturers are inconsistent is solved, and the service lives of lamp tubes and couplers can be prolonged.
