摘要： 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.

摘要翻译： LED灯驱动电路包括：具有一个端子的热敏电阻，通过该端子施加外部电压; 连接到所述热敏电阻的另一端的AC-DC转换单元，将施加到所述热敏电阻的另一端的交流电压转换为直流电压; 以及将来自AC-DC转换单元的DC电压转换为驱动LED灯所需的DC电压的DC-DC转换单元。
