Along with development of science and technology, people have successfully worked out light emitting diode, and light emitting diode is that electricity is to illuminator, electric energy is converted into luminous energy, and luminous efficiency all is greatly improved than tengsten lamp and fluorescent lamp, simultaneously he also to have a volume little, shockproof, advantage such as pollution-free and life-span is long.The appearance of light emitting diode (LED) has caused the revolution of a light fixture industry at once, light emitting diode has replaced tengsten lamp in a lot of fields, become the main flow of lamp light source, but because it exists light-emitting area little, shortcomings such as brightness is low, its application generally only rests on the device lamp, and fields such as indicator lamp are difficult to enter lighting field.

Certainly, many low power LEDs also can be installed in light fixture improve lamp brightness being applied in the illumination, but so the volume of light fixture has very hugely, heavy, only is useful in street lamp and shot-light occasion, still is not suitable for illumination at home; The perhaps brightness of illumination that also can use or a spot of large-power light-emitting diodes to improve at lighting, but because the lumination of light emitting diode area is little, light just seems very dazzling after improving luminosity, simultaneously, also there is the rare problem of heat radiation in large-power light-emitting diodes, still fails fine solution light emitting diode to be applied to the at home problem of illumination.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of structure small and exquisite, the soft and good LED lighting bulb of illumination at home that is applicable to that dispels the heat of light.

The utility model solves above-mentioned technical problem by following technical proposals:

A kind of LED lighting bulb comprises astigmatic shell, is installed on the great power LED in the astigmatic shell, is installed on astigmatic shell outer heat abstractor that is connected with great power LED and the lamp holder that is connected with heat abstractor.

The beneficial effects of the utility model are: because the utility model has adopted high-power LED as light emitting source, improved the brightness of illumination of light fixture, reduced the volume of light fixture; Be covered with astigmatic shell at power LED, the light of great power LED light after astigmatic shell scattering is soft, and it is dazzling to have solved great power LED light, is not suitable for the problem of illumination at home; Great power LED is installed outside astigmatic shell again connects heat abstractor, the heat that great power LED is taken place is dispersed into outside the astigmatic shell, prevents that heat from gathering the generation potential safety hazard in lamp body; In sum, the utility model is that a kind of structure is small and exquisite, the soft and good LED lighting bulb of illumination at home that is applicable to that dispels the heat of light.
