The following specific embodiment will combine above-mentioned accompanying drawing to further specify the present invention.
The specific embodiment
Please refer to Fig. 1 to Fig. 3, the led lamp 10 of the present invention's one preferred embodiment comprises radiator 11, heat pipe 12, light emitting diode 13, drive circuit 14, lamp holder 15 and lampshade 16.
Please be simultaneously with reference to figure 4 and Fig. 5, said radiator 11 comprises connecting portion 111, fin 112 and pad 113.The axis direction of the said connecting portion 111 in one edge of said fin 112 is resisted against the outside of connecting portion 111, and a plurality of said fins 112 are provided with around this connecting portion 111, around this connecting portion 111, form a ring-type first platform 112e.The first platform 112e of fin 112 flushes with the top of connecting portion 111.Fin 112 is shorter than connecting portion 111, and expose outside fin 112 bottom of connecting portion 111.Said pad 113 is a ring-type thin slice, is set on the said connecting portion 111, and the surface of said pad 113 is resisted against on said fin 112 one side away from the said first platform 112e.In one embodiment of the invention, said connecting portion 111 is a tubular structure, the inner accommodation space 111a that forms.Said fin 112 comprises that a body 112a reaches a plurality of connecting portions perpendicular to this body 112a; Be respectively the first connecting portion 112b, the second connecting portion 112c and the 3rd connecting portion 112d; This body 112a is a quadrilateral structure, and the said first connecting portion 112b, the second connecting portion 112c and the 3rd connecting portion 112d are divided on said body 112a three limits wherein.The said second connecting portion 112c against and be connected in the outside of said connecting portion 111, said each first connecting portion 112b and the 3rd connecting portion 112d form the platform of two ring-types respectively, are respectively the first platform 112e and the second platform 112f.The surface of said pad 113 is resisted against on the said second platform 112f.Understandable, the shape of the said first platform 112e and the second platform 112f is not defined as circular, the requirement all according to the invention of any other closed hoop.
Said heat pipe 12 is connected in said radiator 11 tops, and extends said radiator 11 tops.As shown in Figure 6, the heat pipe 12 of one embodiment of the invention comprises evaporator section 121 and condensation segment 122, and this heat pipe 12 is three-dimensional heat pipe, and promptly evaporator section 121 is not located in the same horizontal plane with condensation segment 122.Said evaporator section 121 is positioned at said radiator 11 tops, becomes vacant state, and extends on the axis of said connecting portion 111.Said condensation segment 122 is extended to form by an end of said evaporator section 121, and is welded on the said first platform 112e of said radiator 11, forms thermally coupled with said radiator 11.Can increase the transmission speed of heat greatly through said heat pipe 12, make heat to be delivered to more fast on the radiator 11.This condensation segment 122 extends along this first platform 112e, makes said heat pipe 12 be connected with a plurality of fin 112 direct heat, and heat just can be evenly distributed on each fin 112 like this, can effectively accelerate heat radiation.Understandable, said heat pipe 12 is not limited to one, also can be for a plurality of, and the situation that the shape of said heat pipe 12 also is not limited to present embodiment and is provided.For example: this heat pipe 12 can be two, and perhaps the interlude of heat pipe 12 is that evaporator section 121 is vacant state, and two ends are the top that condensation segment 122 is connected in said radiator 11.
