PURPOSE: An EMI removal circuit for an input terminal of a driver IC is provided to prevent malfunction by eliminating EMI noise in a low frequency band of an input terminal of a head lamp. CONSTITUTION: An LC filter(110) includes an inductor(L1) connected between a power input port of a driver IC(140) and a power supply passed through a diode, and a capacitor(C5) connected between the power input port and the ground. A plurality of capacitors(C1-C4) is connected between the ground the power supply of the driver IC. A first resistor(120) and a second resistor(130) absorb EMI noise. |
