The through hole of described protective cover forms axial step by aluminium base one side in peritreme, the outer wall of small sealing ring and inwall form radially outer lug boss and inner convex platform respectively, the periphery of optical lens forms protruding wall, small sealing ring and optical lens by axial step and outer lug boss cooperate, protruding wall and inner convex platform cooperate and be fixed in the through hole.

The through hole of described protective cover forms concave surface away from aluminium base one side in peritreme.

The periphery of described aluminium base is provided with screw, and correspondence is offered perforation on protective cover and the large sealing packing ring, and screw passes perforation and cooperates with screw, protective cover and large sealing packing ring is assembled in the front of aluminium base.

After adopting such scheme, the utility model compared with prior art has the following advantages:

One, save lampshade, utilize the through hole of optical lens and protective cover to cooperate before LED lamp pearl, realize lens function and lampshade function, the light penetration rate is improved greatly, light distribution effect is better;

Two, radiating subassembly directly is installed on aluminium base, is made module carry heat sinking function, structure is simpler, installs more convenient.

Below in conjunction with the drawings and specific embodiments the utility model is further described.
