Patent ID: 8596814

Claim:
An LED light tube comprising: a light tube body having a first end and a second end; each end having a first electrode and a second electrode; and a circuit module mounted in the light tube body and comprising: a rectifying unit comprising: a first power terminal electrically connected to the first electrode of the first end of the light tube body; a second power terminal electrically connected to the second electrode of the first end of the light tube body; a third power terminal electrically connected to the first electrode and the second electrode of the second end of the light tube body; and two power output terminals that are a first power output terminal and a second power output terminal for outputting a sine wave DC voltage; a current regulating and voltage regulating unit comprising: two input terminals that are a first input terminal and a second input terminal respectively and electrically connected to the first power output terminal and the second power output terminal of the rectifying unit for receiving the sine wave DC voltage; and two output terminals that are a first output terminal and a second output terminal for outputting a working power; and an LED unit electrically connected to the two output terminals of the current regulating and voltage regulating unit for receiving the working power to emit light.
