The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of LED bulb lamp comprises glass lamp shade, led light source, base, Switching Power Supply and lamp holder, and an end of base is connected with lamp holder; It is characterized in that: it also comprises the radiating seat that is fixed on the base; Radiating seat is the alumina ceramic structure that is tubular and end sealing, and described led light source is fixed through metal substrate and radiating seat, and described base is by the one-body molded cylindrical shell that obtains of insulating materials; Base is positioned at radiating seat inside and fixes with radiating seat, and described Switching Power Supply is located in the base.The metal substrate that the utility model provides is fixed on metal cooling seat top, because the thermal conductivity of metal itself, and radiating seat is a hollow metal member, improved the radiating efficiency of bulb lamp.Switching Power Supply places the center of PE material, and base adopts the PE material of high-insulativity, low heat conductivity, when guaranteeing insulation, can effectively reduce the loss of heat to Switching Power Supply.Led light source fixes through metal substrate and radiating seat, and the heat of LED illuminator is passed to radiating seat through metal substrate.
As preferably, described radiating seat is made up of triangle fin, upper surface and support cylindrical shell, and circular upper surface is connected to form " Π " shape structure with supporting cylindrical shell, and the triangle fin is around being provided with in external week of support tube and linking 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 triangle 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.Described through wires hole comprises screw hole.
As preferably, described triangle fin is evenly distributed supporting on the cylindrical shell.This structure makes the radiator structure that is centrosymmetric, and each triangle fin gap equates, is beneficial to the raising radiating efficiency.
As preferably, described triangle fin is with to support cylindrical shell perpendicular.
As preferably, described triangle fin is 20-22.
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, the outer peripheral edges of said upper surface extend upward and form flange upwards.This flange is used for and the glass lamp shade clamping.
As preferably, be provided with radiating block between the adjacent triangle fin, the upper end of radiating block links to each other with the upper surface, has louvre on the radiating block.This structure helps increasing area of dissipation, improves the radiating efficiency of radiating seat.
As preferably, the cross section of described louvre is circular, square or rectangle.
Therefore, the utility model is because radiator 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 like Fig. 1, Fig. 2 and LED bulb lamp shown in Figure 3, form by 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 Switching Power Supply 5 is located in the base.Glass lamp shade 1 and radiating seat 3 clampings.
