Zusammenfassung:	The utility model discloses a highly-efficient LED lamp tube structure, relates to LED illumination, and is used for improving the light extraction rate of a lamp by solving the problem that a part of light radiated from the present lamp is consumed in a lamp tube. The technical scheme is that the highly-efficient LED lamp tube comprises a heat-dissipating metal tube, wherein the heat-dissipating metal tube comprises a heat conductor arranged at the back of a PCB (Printed Circuit Board), a combined part connected with a lamp shade, and a connecting part for connecting the heat conductor and the combined part; and the connecting part is opposite to the heat conductor and upwardly inclines towards the direction of the lamp shade, so as to form a slope serving as a light-reflecting surface; and the heat conductor and the connecting part form an opening structure. Compared with the prior art, the technology of the utility model can satisfy the special requirement of high light flux, can significantly save energy,
