摘要： A power conversion circuit for light emitting diode includes a voltage converter. The voltage converter has two receiving terminals and two output terminals. The two receiving terminals of the voltage converter are electrically coupled to the direct current power supply, and the output terminals output corresponding direct current signals according to the received direct current power supply, to drive a light emitting diode string. One of the output terminals has a positive potential, and another output terminal has a negative potential.
