Abstract:
1. A laminated heat-dissipating and non-disposable LED lamp comprising: a lamp holder being a hollow shell, said hollow shell having one end formed with a threaded section, said hollow shell having another end assembled thereon with a fixing plate, said fixing plate provided with a power converter at one side opposite to said threaded section; an LED luminous module assembled on said lamp holder, said LED luminous module provided with a metal basic plate easy to conduct heat energy, said basic plate inlaid thereon with a circuit board, said circuit board having one side installed with numerous LEDs; a lampshade integrally made of transparent acrylic, said lampshade assembled on said LED luminous module; and a heat dissipation unit covered around a circumferential side of said lamp holder, said heat dissipation unit made of aluminum that is easy to conduct heat energy, said heat dissipation unit axially formed into a multi-ply heat-dissipating layer that is shaped as a tube with plural plies of different diameter, said heat-dissipating layers covered around an outer circumferential side of said lamp hold, a gap formed between every two adjacent plies, each said ply having one end connected with a corresponding end of an adjacent ply and with the other end each ply not connected with the corresponding other end of the adjacent ply, an innermost ply of said heat-dissipating layer of said heat dissipation unit having a free end connected with said basic plate of said LED luminous module so that heat energy produced by said LEDs can be conducted to said heat dissipation unit through said basic plate for achieving effect of heat dissipation.
