Preferably, described heat dissipation channel is evenly distributed on heat-dissipating aluminium plate in a ring around the center of heat-dissipating aluminium plate.
Preferably, 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.
Preferably, the upper end of the lampshade forms enlarging.
Preferably, described lampshade uses aluminium, and the conduit in lampshade uses insulation tube, and conduit is distributed in lampshade The heart.
Preferably, 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 utility model are:Its is simple in construction, and only the radiator structure of LED lamp is optimized and changed Enter, increase area of dissipation and put forward highly thermally conductive speed, so as in the case where not changing LED lamp size, improve LED lamp Radiating efficiency.
