The profile of aforementioned fin is surrounded by top, bottom, inner edge and outside, and wherein upper and lower limit is parallel, and inner edge is vertical with upper and lower limit, and the outside is a curved side.

The thickness of aforementioned each fin is 0.5-0.6mm.

Aforementioned each fin offers a plurality of louvres respectively, and each louvre on each fin is along the curved side arrangement of fin separately.

Aforementioned fin constitutes by upper and lower half section, and a plurality of louvres on it are distributed in lower semisection.

Aforementioned each fin outside is along being respectively equipped with catching groove, and the periphery of described lampshade is provided with clasp, and this lampshade is buckled in each catching groove by clasp and is connected with lamp socket.

Aforementioned pedestal is cylindric, and this pedestal lateral wall is provided with the strip groove that matches with fin along its length direction, and described fin one sidewall is riveted in the strip groove.

Aforementioned aluminium base rear portion is provided with fixed head, and this fixed head is installed in the pedestal by the riveted joint mode.

The aforementioned fixation plate offers the line channel that cooperates with aluminium base.

Aforementioned pedestal madial wall is provided with the groove that is used for fixing aluminium base and is strip, and the length direction of this groove is identical with the pedestal length direction.

Aforementioned lamp body is provided with the heat dissipation channel that is used to dispel the heat.

By above-mentioned description to the utility model structure as can be known, compare, the utlity model has following advantage with prior art:

One, fin adopt riveted way to be connected with pedestal, have made things convenient for and have offered louvre on the fin, have improved lamp socket integral heat sink function.

Its two, the thickness of fin is 0.5-0.6mm, the thickness of comparing existing fin is little, greatly reduces product weight and production cost like this.

Its three, adopt since aluminium base be covered on pedestal one end face and with the fin end face of pedestal one end face homonymy, stoped light to shed like this through the gap that forms between the adjacent fin, solved the easy leakage problem of light.

Its four because the design of groove and heat dissipation channel, can improve the radiating effect of LED bulb integral body, the heat that aluminium base produces is discharged through groove, heat dissipation channel successively; The heat that component produces can be discharged by heat dissipation channel, and the temperature of aluminium base and component generation is unlikely to too high and damages like this.
