The low-beam anti-dazzling control device structurally comprises a third resistor, a reverse protection diode and a fourth resistor. The low-beam anti-dazzling control device is characterized in that one end of the fourth resistor is connected with the signal end of the reverse protection diode; the other end of the fourth resistor leads out the signal line of a low-beam lamp; one end of the third resistor is connected with a negative electrode; the other end of the third resistor is connected with the common terminal of the reverse protection diode; and the collector of the reverse protection diode is connected with the second pin of a control chip. When a dimmer switch is in the position of the low-beam lamp, the reverse protection diode works, the resistance of the second pin of the control chip is decreased, the working frequency of the control chip is also decreased, and the working current of the ballast is decreased to 2.8 A; and when the dimmer switch is in the position of a high-beam lamp, the reverse protection diode stops working, the working frequency of the control chip is increased, and the working current of the ballast is recovered to 3.5 A.
