The specific embodiment

At first see also Fig. 1, Fig. 2, the fitting structure of one embodiment of the invention is made up of an electrical joint 10, a connecting elements 20, a radiating module 30, a lampshade 40 and at least one light-emitting component 50, aforementioned electrical joint 10 for example is the E27 joint, aforementioned light-emitting component 50 for example is a light emitting diode, and 30 of aforementioned connecting elements 20 and radiating modules can comprise the metal material of aluminium or other tool high thermal conductivity coefficients.What need special instruction is, radiating module 30 in the present embodiment mainly is made up of one first heat conducting element 31 and one second heat conducting element 32, wherein first, second

heat conducting element

31,32 can utilize the mode of die cast to make, and 20 of aforementioned connecting elements for example can be made by the mode of the crowded type of metal.

As shown in Figure 1 and Figure 2, be formed with a plurality of first fins 311 on first heat conducting element 31 in the present embodiment, then be formed with a plurality of second fins 321 on second heat conducting element 32, wherein first, second

heat conducting element

31,32 for example can be made (for example aluminium die cast) in the mode of die cast respectively, make first, second

heat conducting element

31,32 chimeric mutually during assembling again, and make first, second fin 311,321 with the interlace mode arranged spaced.Find out that by knowing among Fig. 1 aforementioned light-emitting component 50 is arranged at second heat conducting element, 32 bottom sides, 40 on the lampshade and second heat conducting element 32 mutually combine, in order to coat aforementioned light-emitting component 50.

What need to specify is, because during the fin structure of die-casting and molding technology on making heat conducting element, for the spacing of radiating fin restriction on its size is arranged, so be difficult to reach the purpose that shortens spacing and increase number of fins on actual fabrication.In order to overcome the shortcoming on the traditional manufacturing technique, the present invention assembles in mutual chimeric mode by making first, second
