LED lamp tube

A light-emitting diode (LED) lamp tube, including:

• a hollow transparent tube body;
• a heat-dissipating base disposed in the transparent tube body and engaged with inner walls of the transparent tube body;
• a light-emitting module provided on a first surface of the heat-dissipating base;
• a control circuit module provided on a second surface of the heat-dissipating base to be separated from the light-emitting module;
• an electrical-conductive element penetrating the heat-dissipating base to be electrically connected to the light-emitting module and the control circuit module;
• and
• a pair of electrical-conductive caps covering both ends of the tube body to be electrically connected to the control circuit module,
• wherein two opposite side edges of the heat-dissipating base are bent downwardly toward a first surface thereof to form first inwardly folded edges, a first track is formed on the first surface and defined by the two first inwardly folded edges, and a circuit board of the light-emitting module is guided by the two first inwardly folded edges to slidably fit on the first track;
• wherein the two opposite side edges of the heat-dissipating base are bent upwardly toward a second surface thereof to form second inwardly folded edges, a second track is formed on the second surface and defined by the two second inwardly folded edges, and a circuit substrate of the control circuit module is guided by the two second inwardly folded edges to slidably fit on the second track.
