The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1 to Fig. 3, it is LED radiator provided by the present invention.This radiator comprises a hollow body 1.This hollow body 1 adopts the good material of heat conductivility to make.In this hollow body 1, be provided with passage penetrating Shang Xia one 11.When LED radiator uses, the port of two ends up and down of passage 11 can not seal, and must keep the air circulation of passage 11.The outside of described hollow body 1 is evenly distributed with a plurality of LED light sources 2.Described hollow body 1 inner side is provided with fin 12.And when making this LED radiator, described hollow body 1 adopts integral forming process to complete with described fin 12.
Further, LED radiator provided by the present invention is mainly applied on small-sized light fixture, for example the perpendicular lamp of inserting.And radiating principle of the present invention as shown in Figure 2: when LED radiator uses, the heat energy that LED light source 2 sends is absorbed by the hollow body 1 of LED radiator, then hollow body 1 conducts heat on the fin 12 of its inner side, make fin 12 heatings, the temperature in hollow body 1 inner passage 11 rises thereupon; Due to air be heated after density reduce to float, make originally risings of being heated of the air in hollow body 1 passage 11, from the upper port of hollow body 1, overflow, thereby make the air pressure reduction in passage 11; And air pressure in passage 11 reduces the cold air outside LED radiator is entered in the passage 11 of hollow body 1 from the lower port of hollow body 1, thereby realize the convection current of cold and hot air, reach the effect of heat radiation.
Particularly, in the present invention, as shown in figures 1 and 3, described hollow body 1 is straight-tube shape, and the rounded (not shown) of cross section or polygon.Described LED lamp bar 2 outer side wall surface along described hollow body 1 radially and axially uniform.If hollow body 1 cross section is circular, LED light source 2 is put along its axial rings winding around described hollow body outer surface.But in embodiment provided by the present invention, the cross section of described hollow body 1 is hexagonal structure.Meanwhile, described LED light source 2 is LED lamp bar in the present invention.This LED lamp bar 2 is located at the outer side wall surface of described hollow body 1.As shown in Figure 3, in the present embodiment, always have 6 LED lamp bars 2, and the axially vertically arrangement of LED lamp bar 2 lateral walls along described hollow body 1.And this LED lamp bar 2 comprises substrate and a plurality of LED lamp being fixed on described substrate.This LED lamp number can free setting.Particularly, described substrate is finally directly fixed in the outer side wall surface of hollow body of radiator.Hexagonal cross section of hollow body 1 facilitates the substrate of LED lamp bar 2 to be fixed on the outer surface of radiator.And by LED light source 2 around being arranged on the lateral wall of whole LED radiator, on the one hand in order to obtain larger light source luminescent face, the installable position of LED light source 2 is wider, is to be on the other hand uniformly distributed the heat that LED light source 2 sends, and makes LED radiator thermally equivalent.Therefore, the heat absorption that LED radiator sends LED light source and release are more even, and the utilization rate of radiator is better.
Further, please again referring to Fig. 1 to Fig. 3, described fin 12 is arranged on the internal chamber wall of described hollow body 1, and corresponding along the setting position of described hollow body 1 with described LED light source.A plurality of flat members that described fin 12 radially extends for the internal chamber wall along described hollow body 1.In the inside of LED radiator, fin 12 is set, has increased the area of dissipation in radiator inner passage 11, improved the radiating effect of the hollow heat radiation of thermal convection current.Meanwhile, fin 12 is corresponding along the position of described hollow body 1 with the LED light source 2 in outside, and the heat that LED light source 2 distributes can be more effectively directly transmitted on fin 12.And fin 12 is placed in the inner side of hollow body, in the passage 11 of air thermal convection current, be not easy to pile up dust, the stability of heat radiation is better, and more compact attractive in appearance on this LED heat spreader structures.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
