Beschreibung
Zusammenfassung:	An embodiment comprises: a voltage generation unit for providing a direct current signal for driving a light emitting unit; a sensing resistor; and a dimming unit which is connected between the light emitting unit and the sensing resistor and controls a current flowing in the sensing resistor and the light emitting unit, wherein the dimming unit adjusts the level of the direct current signal on the basis of a first sensing voltage as a result of sensing the voltage of a first node where a switch is connected to the light emitting unit, and a second sensing voltage as a result of sensing the voltage of a second node where the switch is connected to the sensing resistor.
