Disclosed is a smart dimming converter apparatus. The smart dimming converter apparatus of the present invention comprises: a power supply unit which receives commercial alternating current power inputted thereto, stabilizes and rectifies the inputted power, and actively compensates for a power factor and outputs direct current power; a pulse-width control unit which switches the direct current power outputted from the power supply unit by pulse-width modulation, and outputs the switched direct current power; a DC-DC converter unit which receives the direct current power outputted from the pulse-width control unit and inputted thereto, and converts the inputted direct current power to direct current voltage for driving an LED; and an output current smoothing unit, which removes the alternating current component from the direct current voltage outputted from the DC-DC converter unit, converts the voltage to the voltage having a current of an average value, and outputs the converted voltage to an LED light. According to the present invention, the brightness of the LED light can be adjusted while preventing a flickering phenomenon even in the event of low current. |
