The transistor switch has a control terminal, a first terminal, and a second terminal. The first terminal is coupled to the LED module and the control terminal receives a control signal for controlling a current passing through the transistor switch. The feedback controller receives a reference voltage and a current detecting signal indicative of the magnitude of the current and generates the control signal accordingly. The feedback controller is connected to a driving power source with level higher than the level of the first terminal of the transistor switch.
