Detailed description of the invention
Hereafter in conjunction with the accompanying drawings and embodiments the utility model is described further.
Embodiment one
With reference to figure 1, a kind of LED bulb, comprising: bulb shell 1, support 2, lamp holder 3, LED module 4;
The openend of lamp holder 3 is stretched in one end of described support 2, and fixes with described lamp holder 3; In the present embodiment, described fixing mode is that spiral is fixed.Described bulb shell 1 stretches into the openend of described lamp holder 3 and described lamp holder 3 is fixed, and described support 2 is accommodated into the inside of described bulb shell 1 with described lamp holder 3 completely; Described LED module 4 is attached at the surface of described support 2, and the thermal conduction portions 41 of described LED module is arranged at the inside of described support 2; Described support 2 inside is provided with heat-transfer device 21, and the heat conduction thermal conduction portions 41 of described LED module sent to described lamp holder 3 part, and dispels the heat.
In the present embodiment, described heat-transfer device 21 is heat-conducting glue, is filled in the inside of described support 2 by the mode of encapsulating, thus reaches heat conduction extremely described lamp holder 3 place thermal conduction portions 41 of described ED module sent, and dispels the heat.Because the material of lamp holder 3 is metal, so adopt in this way, radiating efficiency is very high, can reduce the operating temperature of described LED module 4 well, thus extend the service life of LED module.
Described support 2 can select transparent material or non-transparent material, and when selecting transparent material, such as PC or glass, because material possesses good light transmission, the light-emitting area of described LED module 4 can be placed in the inside of described support 2.
When non-transparent material selected by described support 2, such as metal or plastics, the light-emitting area of described LED module 4 needs the outside being placed at described support 2, the thermal conduction portions 41 of described LED module 4 is passed the surface of described support 2 simultaneously, is arranged on the inside of support 2.
Because LED illuminating module 4 is arranged on support 2, the distribution mode of such LED illuminating module has had very large change compared to the distribution mode of traditional straight-down negative luminescence.There is the arrangement mode of distribution like this at vertical direction and horizontal direction, add the lighting angle of LED bulb.
