Abstract
A light emitting diode (LED) lamp tube heat dissipating structure is capable of dissipating heat in a tube quickly to improve the heat dissipating efficiency. A circuit board with a light radiating surface and a heat dissipating surface is contained in the tube, and the light radiating surface of the circuit board is electrically connected to LED lamps. Two conductive bushings are sheathed onto both ends of the tube and electrically connected with the circuit board, and at least one heat dissipating hole is disposed separately on both distal surfaces of the tube that covers the heat dissipating surface of the circuit board, such that external air is entered into the tube from the heat dissipating hole on a distal surface of the tube and dispersed from the heat dissipating hole on another distal surface of the tube for dissipating the heat in the tube.
