If the dimmer is not normally off. When the LED lamp is powered on, the conduction angle is small, because non-pure resistive devices such as capacitors and inductors exist in the driving circuit, the input current must generate certain oscillation, when the oscillation enables the input current to be smaller than the holding current of the dimmer, the dimmer is cut off to enable the LED lamp to be turned off, and the LED lamp band is turned off; when the oscillation makes the input current larger than the conduction current of the dimmer, the dimmer conducts to enable the LED lamp to emit light. If the on-off frequency of the dimmer is too low, the LED lamp flickers. In the control circuit, an auxiliary leakage loop consisting of a capacitor C2, a resistor R3 and a capacitor C3 is arranged. The auxiliary leakage loop can reduce the oscillation degree of the input current to a certain extent, and the condition that the dimmer is cut off by mistake is avoided.
