Form and be connected with heat dissipation channel on heat-dissipating aluminium plate on the intracavity inter-connection of the passage of heat, heat dissipation channel and round platform, the side wall of lampshade
Heat-dissipating aluminium plate bottom surface between logical heat emission hole, adjacent heat radiation passage is against there is cushion block, and screw is screwed onto pad through heat-dissipating aluminium plate
On block, cushion block is fixed on baffle plate, and baffle plate grafting is fixed in lampshade, and conduit, the upper end of conduit are plugged with described baffle plate
It is fixed on the bottom surface of round platform, forms to be fixed with wire via, the top surface of round platform on pcb board, pcb board on round platform and fix
LED chip.
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
