It is preferred that, described heat dissipation channel is evenly distributed on heat-dissipating aluminium plate in a ring around the center of heat-dissipating aluminium plate.
It is preferred that, if forming the fin of arterial highway circular arc on the bottom surface of the heat-dissipating aluminium plate, the height of fin is small In the thickness of cushion block.
It is preferred that, the upper end of the lampshade forms enlarging.
It is preferred that, described lampshade uses the conduit in aluminium, lampshade to use insulation tube, and conduit is distributed in lampshade The heart.
It is preferred that, the upper surface of heat dissipation channel is higher than the upper surface of round platform on the heat-dissipating aluminium plate.
The beneficial effects of the present invention are:Its is simple in construction, only optimizes improvement to the radiator structure of LED lamp, increases Plus area of dissipation and highly thermally conductive speed is put forward, so as in the case where not changing LED lamp size, improve dissipating for LED lamp The thermal efficiency.
