Quick heat-radiation light emitting diode (LED) garden lamp

The invention relates to the field of an illumination lamp, in particular to a quick heat-radiation light emitting diode (LED) garden lamp having a good heat radiation effect, which aims to solve the heat radiation difficulty of the present LED lamp, and has fast heat radiation speed and large amount of heat radiation. The invention adopts a technical scheme that: the quick heat radiation LED garden lamp consists of a lamp holder, a heat radiator and a lamp adapter, which are sequentially connected with each other from top to bottom, wherein an axial through hole is arranged in the middle of the heat radiator, the periphery of the through hole is provided with heat radiation sheets, the upper end of a heat conducting bar is embedded inside the through hole, the lower end surface of the heat conducting bar is sequentially provided with a binding layer, an insulation layer substrate, a copper-clad layer and an insulation layer, and LED lamp beads are welded on the heat conducting bar through a tin soldering lay
