Patent abstract
The present disclosure relates to a regulating circuit capable of preventing low-temperature flickering of an light-emitting diode (LED) lamp, including a negative-temperature-coefficient resistor, a forty-sixth linear resistor, a forty-seventh linear resistor, a forty-eighth linear resistor, a fifty-second linear resistor, a fifty-third linear resistor, a fifty-fourth linear resistor, a fourth triode, a fifth triode, a voltage stabilizing diode, an eighth diode, and a common mode choke. The beneficial effect is that a dimming circuit can raise a dimming voltage to around 4 V at −20° C., such that a main control chip exits a burst mode.
