Abstract: An adaptive LED dimming driving circuit is disclosed, wherein its control module is disposed with a first resistor, a second resistor, a retainer, a third resistor and a fourth resistor. When the control module receives an input voltage, the retainer is driven to output a retaining current Ihold to the second resistor, thereby ensuring normal dimming. The first resistor and the third resistor detect the input voltage so that when an input current Iin satisfies a correlation Iin=Ihold+ILED, the retaining current has the minimum value to increase work efficiency during the LED that is dimmed to the maximum intensity. When the input voltage is too low, the reference level is reduced to prevent the LED from generating twinkling. The fourth resistor detects the voltage energy of the LED. Therefore, when the voltage energy is changed, a high-low-voltage compensation is performed to achieve a constant power state.
