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 4):
The LED driver circuit of  claim 3 , further comprising:\n a load current detecting unit detecting the amplitude of the current flowing through the LED string; and a transistor current detecting unit detecting the amplitude of the current flowing through the transistor, wherein the voltage value on the gate terminal is dependent on the amplitudes of the analog signal, of the current flowing through the LED string and of the current flowing through the transistor.
