1. A light-emitting diode light tube driving circuit used in a lamp socket with a ballast, the light-emitting diode light tube driving circuit comprising:
a light-emitting diode driver configured for receiving an operating voltage to drive at least one light-emitting diode; and a rectifier unit having a first input/output terminal and a second input/output terminal, and electrically coupled to an external alternating-current power source selectively through the first input/output terminal and the second input/output terminal, and configured for providing the operating voltage to the light-emitting diode driver, the rectifier unit comprising:
a first rectifier diode, an anode of the first rectifier diode being electrically coupled to the light-emitting diode driver, a cathode of the first rectifier diode being electrically coupled to the first input/output terminal and the second input/output terminal; anda second rectifier diode, an anode of the second rectifier diode being electrically coupled to the cathode of the first rectifier diode, the first input/output terminal and the second input/output terminal, and a cathode of the second rectifier diode being electrically coupled to the light-emitting diode driver. |
