The specific embodiment

Fig. 1, Fig. 2 and Fig. 3 are respectively three-dimensional exploded view of the present utility model, stereo appearance figure and assembled sectional view.As Fig. 1, Fig. 2 and shown in Figure 3, LED light fixture cover body radiator structure of the present utility model can make lamp socket 3 that its thermal source is reached on the heat-sink unit 2, and flow to corresponding heat radiation runner 22 and channel part 11 by the through hole on the lid 4 41 guiding outer gas streams, thereby the thermal source on the heat-sink unit 2 is taken out of, so that the LED light fixture can be gone out thermal source dissipation effectively.

The above-mentioned LED light fixture of carrying comprises: lampshade 1; Heat-sink unit 2; Lamp socket 3 and lid 4.Lampshade 1 has channel part 11, and channel part 11 can be horizontal elongated slot or is located on by a plurality of through holes on the perisporium of lampshade 1, and present embodiment is an elongated slot.In lampshade 1, has joint portion 12.Heat-sink unit 2 can be made by aluminium, copper or other thermal conductivity good metal material, is nearly semicircle sphere.Heat-sink unit 2 has engaging groove 21, is inserted in by engaging groove 21 on the joint portion 12 of lampshade 1, so that heat-sink unit 2 is provided with and is linked in the lampshade 1.And have the heat radiation runner 22 corresponding on the heat-sink unit 2 with channel part 11, heat radiation runner 22 is located on the top periphery of heat-sink unit 2, and its shape can be the kenel of indent semicircle, indent rectangle, indent V-arrangement or other various different geometries, and present embodiment is the indent semicircle.Lamp socket 3 comprises circuit board 31 and is arranged at illuminator 32 on the circuit board 31.Illuminator 32 can be light emitting diode, and lamp socket 3 is arranged on the heat-sink unit 2 by circuit board 31.Lid 4 is covered on an end of lampshade 1, has on the lid 4 and the corresponding through hole 41 of heat radiation runner 22.And the centre of this lid has through hole 42, is provided with leaded light piece 43 in the through hole 42.Leaded light piece 43 has the projection unit 44 (as shown in Figure 3) corresponding with illuminator 32.Thus, by the combination of said modules, can form brand-new LED light fixture cover body radiator structure.

Fig. 4 and Fig. 5 are respectively combination vertical view of the present utility model and user mode schematic diagram.As shown in Figure 4 and Figure 5, during use, electric power is connected conducting on lamp socket 3, make illuminator 32 luminous and penetrate light source so that illumination to be provided.Illuminator 32 produces thermal source in the time of luminous, this thermal source is absorbed by heat-sink unit 2, and utilize the natural convection air effect, through hole 41 on the lid 4 just guides outer gas stream, enter in the heat radiation runner 22 of heat-sink unit 2, treat that this outer gas stream flows through behind the heat radiation runner 22, derive by the channel part 11 of lampshade 1.So, lamp socket 3 is reached its thermal source on the heat-sink unit 2, and flow to corresponding heat radiation runner 22 and channel part 11, thereby the thermal source on the heat-sink unit 2 is taken out of, effectively thermal source dissipation is gone out by the 41 guiding outer gas streams of the through hole on the lid 4.

In sum, the utility model LED light fixture cover body radiator structure can effectively improve known various shortcoming, flow to corresponding heat radiation runner and channel part by the guiding of the through hole on lid outer gas stream, thereby the thermal source on the heat-sink unit is taken out of, with efficiently radiates heat, and then make generation of the present utility model can more progressive, more practical, more meet user's needs.
