An LED driving circuit and an LED lamp are provided. The driving circuit comprises a power input unit coupled to an input voltage; a voltage conversion unit coupled to the power input unit and converting the input voltage into a conversion voltage; a power output unit coupled to the LED light source; a first thermistor unit connected between the power input unit and the voltage conversion unit; a second thermistor unit connected between the voltage conversion unit and the power output unit, where the second thermistor unit and the conversion voltage generates a driving current passing through the LED light source; where the resistance of the first thermistor unit is positively correlated to its sensed temperature, and the resistance of the second thermistor unit is positively correlated to its sensed temperature to stabilize the driving current.
