That is to say, in the utility model, the first radiator 110 and the second radiator 120 can split independent use, come for different LED light fixtures thereby the first radiator 110 and the second radiator 120 can be used separately as two independent radiators of heat-sinking capability less.Perhaps, the first radiator 110 and the second radiator 120 can fit together use, thereby can form the 3rd radiator with larger heat-sinking capability.Thereby, can form three kinds of radiators with different heat-sinking capabilities by the first radiator 110 and the second radiator 120.
Can imagine, according to design of the present utility model, a plurality of the second radiators 120 can be set, as long as by layout or the shape of complementation, they are reasonably mated and tighten together.By increasing the quantity of the second radiator 120, can further increase the heat-sinking capability of heat abstractor 100.
With reference to shown in Figure 3, the first radiator 110 has the first radiating fin 111, and the second radiator 120 has the second radiating fin 121.Again as shown in Figure 2, the first radiating fin 111 and the second common the 3rd radiating fin that consists of the 3rd radiator of radiating fin 121.

As shown in Figure 3, the first radiating fin 111 and the second radiating fin 121 can form and be of similar shape, thereby can be so that the outward appearance of the 3rd radiating fin of formed the 3rd radiator is consistent.
As shown in Figure 3, the first radiator 110 can further comprise First body 112, the first radiating fin 111 stretches out from First body 112, the second radiator 120 further comprises the second body 122, the second radiating fin 121 stretches out from the second body 122, and the second radiating fin 121 forms has the shape that matches with First body 112.more particularly, as shown in the figure, First body 112 forms has cylindrical shape, the inward flange of each the first radiating fin 111 has the first curved shape that coordinates with cylindrical shape thereby each in the first radiating fin 111 is all extended also from First body 112 straight up and radially outwardly, each in the second radiating fin 121 all from the second body 122 radially outwardly and verticallydownwardly extends and thereby the inward flange of each the second radiating fin 121 has second curved shape identical with the first curved shape, and the second radiating fin 121 matches with cylindrical shape by the second curved shape.
Certainly, according to the utility model, the first radiating fin 111 and the second radiating fin 121 can have other shape, as long as this shape makes the second radiating fin 121 easily match on the first radiator 110 and consistent with the first radiating fin 111 in shape.But as required, the first radiating fin 111 and the second radiating fin 121 also can be arranged to have different shapes.
Heat abstractor shown in the drawings is to realize by the first radiating fin 111 and the second radiating fin 121 layout along the complementations that make progress in week, but the utility model is not limited to this.For example, the first radiating fin 111 and the second radiating fin 121 can be arranged to have the same distribution along circumferential, but while the first radiating fin 111 and the second radiating fin 121 are arranged to have complementary shape.
For example, can imagine with reference to Fig. 1 or 2, in the situation that with the heat abstractor horizontal positioned, each radiating fin is divided into upper and lower two parts along a horizontal plane, the first radiating fin of the first radiator 110 is arranged to have the shape that is positioned at the fin under horizontal plane, and the second radiating fin of the second radiator 120 is arranged to have the shape that is positioned at the fin on horizontal plane.In when assembling, make in the first radiating fin each with the second radiating fin in corresponding one aim at, thereby form the 3rd radiating fin with continuous profile.
Below, the second radiator 120 is assembled into structure and the method for the first radiator 110 with reference to Fig. 3 and 4 explanations.
As shown in the figure, the first radiator 110 has hole 113, the second radiators 120 and has protuberance 123.In when assembling, can be simply the protuberance 123 of the second radiator 120 be inserted in the hole 113 of the first radiator 110 and the second radiator 120 is assembled into the first radiator 110.
In order to guarantee the fixed effect between the first radiator 110 and the second radiator 120, the cooperation of hole 113 and protuberance 123 can form tight fit.But the fixed form between the first radiator 110 and the second radiator 120 is not limited to this.For example, replacedly, the bottom surface of hole 113 and protuberance 123 can be bonded together by the thermal interfacial material 143 such as heat-conducting glue, thereby realizes purpose fixing and heat radiation.Again for example, replacedly or additionally, hole 113 and protuberance 123 are fixed together by fastening structure.Fastening structure for example can be screw 141, and screw 141 can be fixed in the second radiator 120 on the first radiator 110 by means of pad 142.Certainly, fastening structure for example also can replace to buckle.
Preferably, for convenient the first radiator 110 and the second radiator 120 when the assembling aligned with each other (for example, the second radiating fin 121 that makes the second radiator 120 is positioned at correct position with respect to the first radiating fin 111 of the first radiator 110), can be provided with corresponding align structures on the first radiator 110 and the second radiator 120, thereby the first radiator 110 and the second radiator 120 are aligned with each other by align structures.For example, can be provided with the groove (not shown) that in axial direction extends in the inwall in the hole 113 of the first radiator 110, correspondingly, can be provided with the raised line (not shown) that extends along the longitudinal direction of protuberance on the protuberance 123 of the second radiator 120.When mounted, align and raised line is inserted in groove by the groove with the raised line on protuberance 123 and hole 113, can realize that the second radiating fin 121 is with respect to the accurate location of the first radiating fin 111.
According to the utility model, its by the first radiator and the second radiator detachably with as independent radiator with and capable of being combined using as the radiator with larger heat-sinking capability, can be with the low-cost and simple structure radiator of realizing having multiple different heat-sinking capabilities.For manufacturer, the manufacturing of radiator is oversimplified; And for the terminal use, can realize the flexibility of the upgrading of light fixture, and in the time need to upgrading to obtain higher illumination intensity to light fixture, can originally realize by less one-tenth.
