As preferably; Described radiating seat is made up of triangle fin, upper surface and support cylindrical shell; Circular upper surface is connected to form " Π " shape structure with supporting cylindrical shell, and the triangle fin is around the inwall setting of supporting cylindrical shell, and the top of triangle fin links to each other with the upper surface.Good and the Stability Analysis of Structures of the radiating seat thermal diffusivity of this structure.There is the gap between the leg-of-mutton radiating fin, therefore increased air and flowed, strengthened the radiating efficiency of radiating seat.
As preferably, have some through wires holes on the described upper surface.Through wires hole be Switching Power Supply with led light source be connected the electric wire via hole.
As preferably, described triangle fin is evenly distributed supporting on the cylindrical shell.This structure makes the radiating seat structure that is centrosymmetric, and each radiating fin gap equates, is beneficial to the raising radiating efficiency.
As preferably, described triangle fin is with to support cylindrical shell perpendicular.
As preferably, radiating seat is smooth one-time formed copper member or an al member of outer wall, and described radiating fin is 16-24.Copper member or al member material thermal conductivity are better relatively, and cost is cheap relatively, make radiating effect preferable.
As preferably, described led light source is monochromatic source or Colour-change light source.Led light source can one uses separately, and many combinations that also can be are used, and can confirm according to actual needs at most.
As preferably, support the circumferencial direction of cylindrical shell barrel and between adjacent triangle fin, be provided with several thermovents.
As preferably, the middle part of base is provided with an annular stage body, and described louvre is distributed on this annular stage body.More preferably, described louvre is 8-12.
Therefore, the utility model is because radiating seat is a fin structure, when having increased the surface area of radiating component, more efficient use the circulation of air, reach lasting, radiating effect efficiently, the service time that therefore can prolong led light source with increase efficiency.

The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment 1:
A kind of bulb lamp like Fig. 1, Fig. 2, Fig. 4 and high-power LED light source shown in Figure 7 is made up of glass lamp shade 1, led light source 2, radiating seat 3, metal substrate 4, Switching Power Supply 5, base 6 and lamp holder 7.Led light source 2 is fixed on the radiating seat top through metal substrate 3, and base 6 is that one end of base is threaded with lamp holder 7 by the one-body molded cylindrical shell that obtains of PE material, the other end and radiating seat 3 sockets.Base is positioned at radiating seat inside and fixes with radiating seat, and the middle part of base is provided with an annular stage body 62, has the louvre 61 that communicates with the radiating seat inner chamber on the annular stage body, and louvre is that vertical direction is provided with (see figure 6).The number of louvre is 10.Switching Power Supply 5 is located in the base.Glass lamp shade 1 and radiating seat 3 clampings.
