The upper end of described lamp body is provided with several through holes, and corresponding through hole is provided with screw in the inner side of lamp socket, and trip bolt is screwed on screw through through hole.

Described heat transmission gas pore size distribution is arranged on the upper end-face edge of lamp body, between lampshade and LED module, the outside of lamp body corresponding heat radiation pore is provided with radiating opening groove, the outer end of lamp socket is provided with the fixture block coordinating with open slot clamping.Described radiating opening groove is indent elongated slot, the 1/2-4/5 that its length is lamp body, and many be distributed on lamp body outside.

Described LED module is comprised of aluminium base and some LED light sources, is respectively equipped with heat-conducting silicone grease layer between aluminium base and LED light source, lamp body.

The bottom surface of described reflector is close on the surface of aluminium base, and connecting screw is fixed on the upper end of lamp body successively through reflector, aluminium base.

Described lamp body adopts high-voltage cast-aluminum to make, and lamp socket adopts high heat-conducting plastic to make.

Described lamp holder adopts riveted joint or is threaded with lamp socket.

The utility model is simple in structure, novel, appearance looks elegant, good heat dissipation effect.The heat that LED light source produces is transmitted on lamp body by aluminium base, and the form that at this moment the heat some on lamp body is penetrated with width by external surface area is fallen apart in air; Another part heat is passed to lamp socket by heat conducting form, and the form that heat on lamp socket is penetrated with width by external surface area is fallen apart in air; Also there is quite high heat lamp body and lamp socket inside, and the fit clearance of surrounding and the heat radiation pore on lamp body just import to these heats in air and go with the heat radiation form of convection current.This double-deck heat radiation has improved the stability of electrical equipment, has extended the service life of electronics unit device simultaneously.
