LED lamp easy to dissipate heat and capable of emitting light from four sides

The invention discloses an LED lamp easy to dissipate heat and capable of emitting light from all sides. The LED lamp comprises a superconducting heat pipe, a metal cylinder, an LED module, a wire, a metal cover, packaging glue and a heat dissipation device. The lower end of the superconductive heat pipe and the first through hole are welded into a whole through solder paste, the LED module is welded to the four faces of the upper end of the superconductive heat pipe through solder paste, meanwhile, the faces are kept flush, and the light source is positioned by setting two sections of diameter difference through the metal column body and then assembled on the heat dissipation device through pressing rivet to be formed into a whole. The superconducting heat pipe and the metal column body are combined to serve as a heat conduction carrier, the conduction distance can be effectively shortened, the conduction contact area is increased, the heat conduction performance is improved, and the lighting effect and the
