A light emitting diode (LED) lamp tube structure includes a tube, a circuit board, a plurality of LED lamps, two electric connectors and a protecting cover. The tube includes a plurality of heat dissipating holes. The circuit board is installed in the tube. The LED lamps are installed on the circuit board and electrically coupled to the circuit board. The two electric connectors are connected to both ends of the tube and electrically coupled to the circuit board. The protecting cover is installed onto the LED lamp tube and includes a board, and through holes disposed on the board and corresponding to the heat dissipating holes. Therefore, the LED lamp tube structure achieves a good heat dissipating effect and enhances the life of the LED lamp tube.
