An LED lamp tube includes: a nanotube made of nano-scale material, wherein the nanotube has an elongated shape, and opposite ends of the nanotube are opened; two connecting terminals connected to opposite ends of the nanotube, respectively; and an LED light bar mounted in the nanotube, the LED light bar being connected to an external power supply via a driving circuit board and the connecting terminals. Light emitted by the LED light bar is emitted directly through the nanotube, and the nanotube is configured to absorb heat generated by the LED light bar and dissipate the heat into air. |
