Light emitting diode driving circuit
A light emitting diode driving circuit is provided for driving a first LED unit and a second LED unit. The light emitting diode driving circuit includes a power supply, a detection unit, a serial-parallel circuit, and a control unit. The serial-parallel circuit is coupled to the first LED unit and the second LED unit and establishes a serial connection or a parallel connection for the first LED unit and the second LED unit. The detection unit is coupled to an output end of the power supply for generating a corresponding detection signal according to an output voltage of the power supply. The control unit is arranged between the detection unit and the serial-parallel circuit. The control unit determines the first LED unit and the second LED unit to be set up in the serial connection or in the parallel connection according to the corresponding detection signal.
