The specific embodiment

For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment of heat radiation lamp socket, structure, feature and effect thereof according to the LED light fixture that the utility model proposes, describe in detail as after.

About aforementioned and other technology contents, characteristics and effect of the present utility model, in the middle of following cooperation describes in detail with reference to graphic embodiment, can clearly present.

See also Fig. 1, it is the outside drawing according to the heat radiation lamp socket of the LED light fixture of the utility model one embodiment.As shown in Figure 1, include a radiating shell 100 and a plurality of passages of heat 200 according to the utility model one embodiment heat radiation lamp socket.

On the implementation, radiating shell 100 is made with the good metal of thermal conductivity (for example aluminium, copper or its alloy) or nonmetal (for example graphite), and radiating shell 100 can be any geometric type body.

Radiating shell 100 has a consecutive roof 110 and a sidewall 120, and encloses in roof 110 and the sidewall 120 and form an accommodation space 130.Sidewall 120 has one first relative end 121 and one second end 122, and roof 110 is connected in first end 121 of sidewall 120.The outer wall of sidewall 120 also is provided with a plurality of concavo-convex grooves 123, in order to promote the area of dissipation of radiating shell 100.

A plurality of passages of heat 200 run through first end, 121 to second ends 122 of the sidewall 120 of being located at radiating shell 100.By passage of heat 200, make radiating shell 100 not only can have outside the heat conducting radiating effect, still can make the radiating effect that has natural convection air between first end 121 of radiating shell 100 and second end 122 according to its set passage of heat 200 according to its roof 110 and sidewall 120.
