Embodiment 1
[0022] Such as figure 1 , 2 As shown, the fast heat dissipation LED garden light is composed of a lamp holder 1, a radiator 2, and a lamp holder 3 sequentially connected from top to bottom. The cooling fins 7 are arranged around the circumference of the through hole, and diverge around the central axis of the through hole 6; the cylindrical heat conducting rod 4 made of copper has excellent thermal conductivity, and its upper end is embedded in the through hole 6 , and use interference fit; such as image 3 As shown, an adhesive layer 11, an insulating substrate 12, a copper clad layer 13, and an insulating layer 14 are sequentially arranged on the lower end surface of the heat conducting rod 4, and two LED lamp beads 5 are welded to the heat conducting rod 4 through a solder layer 17; Wherein, the center point 18 of the LED lamp bead 5 is welded and fixed to the lower end surface of the heat conducting rod 4 through the solder layer 17 .
[0023] The copper clad layer is t...
