Abstract
An LED tube comprises a glass tube, a PCB disposed in the glass tube, a heat-dissipating colloid disposed in the glass tube, a plurality of LED lights disposed on the PCB, and two electrode caps respectively connected to both ends of the glass tube. By densely filling a room between a peripheral wall of the glass tube and a top surface of the PCB with the heat-dissipating colloid, an exhaust heat caused by illuminating the LED lights and a high temperature generated from the PCB are absorbed and dissipated out of the tube, thereby constructing a connective dissipating concatenation of heat conduction. A heat-disipating unit can be preferably disposed at an exterior periphery of the tube to obtain a quick and multiple heat-dissipating effect and decrease the temperature in the glass tube, thereby facilitating the illuminating efficiency and increasing the duration of the LED tube.
