Abstract:
An LED lamp driving circuit includes: a thermistor having one terminal through which an external voltage is applied; an AC-DC conversion unit connected to the other terminal of the thermistor and converting an AC voltage applied to the other terminal of the thermistor into a DC voltage; and a DC-DC conversion unit converting the DC voltage from the AC-DC conversion unit into a DC voltage required to drive the LED lamp.
