The invention relates to an LED light tube and a circuit module for the same, wherein the circuit is located in a light tube body and includes a rectifying unit, a current regulating and voltage regulating unit, and an LED unit. The light tube body can be installed in a lamp-holder of a fluorescent tube without changing a starter and a ballast. The rectifying unit has two power terminals connected to electrodes of the light tube body for receiving a mains power and the rectifying unit via the electrodes. The rectifying unit converts the mains power to a sign wave DC voltage. The current regulating and voltage regulating unit is connected to the rectifying unit for converting the mains power to a working power. The LED unit is electrically connected to the current regulating and voltage regulating unit for receiving the working power to emit light. |
