Abstract
A Light Emitting Diode (LED) light tube is applied to be directly inserted to two pairs of electrode insertion holes of a fluorescent light tube fixture to replace a fluorescent tube. The LED light tube comprises a heat-dissipating base, a plurality of linear-extend LEDs and a light-transmissible shell, wherein an arrangement surface of the heat-dissipating base is arranged with the linear-extend LEDs, a peripheral surface of the heat-dissipating base is formed with a plurality of heat-dissipating grooves, two end-surfaces of the heat-dissipating base are respectively connected a pairs of electrodes to be inserted into the electrode insertion holes, and the light-transmissible shell including an opening for covering and assembling to the arrangement surface to package the linear-extend LEDs with the heat-dissipating base.
