Abstract: The invention provides a light emitting device driving circuit, comprising a rectification unit, a current limiting unit and a load. The load comprises a first light emitting device, a reverse voltage providing unit and a second light emitting device connected in serial. When the rectification unit rectifies an alternate current voltage to output a direct current voltage, and the current limiting unit limits the direct current in a predetermined value, the direct current is provided to the first light emitting device or the second light emitting device for operation. The reverse voltage providing unit provides a reverse voltage to reduce the total operating voltage of the light emitting devices in order to enhance the driving efficiency and the power factor.
