1. An LED driving circuit comprising:

  • a power supply;

    an LED array to receive a signal of the power supply;

    an IC connected to the LED array; and

    an inrush current restricting part to gradually increase an output current recognized in the IC,wherein the inrush current restricting part comprises at least one of a frequency adjusting part and a current adjusting part,wherein the frequency adjusting part comprises an FET, a capacitor, and a resistor, and wherein one end of the resistor is connected to a ground terminal, and an opposite end of the resistor is connected to a gate of the FET, andwherein the current adjusting part comprises an FET, a capacitor, and a resistor, and wherein one end of the capacitor is connected to a ground terminal, and an opposite end of the capacitor is connected to a gate of the FET.
