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 10):
The method for driving LEDs of  claim 9 , 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 electrically connecting a first terminal of a transistor to a load circuit related to the LED string; and electrically connecting a second terminal of the transistor to ground, wherein a voltage value on a gate terminal of the transistor is dependent on the amplitude of the analog signal.
