Abstract:
The present invention provides an LED driver circuit, comprising a voltage converter electrically connected to a power supply and an LED string, wherein the voltage converter provides a fixed voltage to the LED string; and a current-based light-adjusting unit electrically connected to the voltage converter, wherein the current-based light-adjusting unit controls the amplitude of the current flowing through the LED string, in an analog manner and based on a duty cycle of a pulse width modulation signal.

Claim (Index 9):
The method for driving LEDs of  claim 8 , wherein controlling the amplitude of the current flowing through the LED string, in an analog manner and based on a duty cycle of a pulse width modulation signal, includes:\n receiving the pulse width modulation signal and converting the pulse width modulation signal to an analog signal whose amplitude is dependent on the duty cycle of the pulse width modulation signal.
