Technical field

The utility model relates to LED lighting field, particularly a kind of lamp holder heat-dissipating LED ball bulb lamp.

Background technology

LED light source has advantages of that luminous efficiency is high, power saving and the life-span long, so its application is more and more extensive.Because LED light source is when luminous, the temperature of himself can raise gradually, in the continuous firing process of lighting device, if the heat that LED light source produces cannot leave in time, will cause this light source assembly damage and affect service life of lighting device.At present, the LED bulb of prior art is generally dispelled the heat by independent radiating piece, and for example Granted publication day is on April 25th, 2012, and the Chinese utility model patent that the patent No. is 201120307527.0 has disclosed a kind of LED lamp bulb radiating structure.This LED lamp bulb radiating structure comprises bulb rack and rack-mount fin, these fin directly contact with the radiator portion of LED lamp body, make heat can be delivered on fin, fin distributes radially and is provided with a plurality of heat radiation through holes, the bottom surface of Lamp cup part is provided with a plurality of openings that allow fin penetrate, and fin is penetrated fixing by opening.

Although this method can play the effect of heat radiation, but a plurality of fin need to be set, and Lamp cup part will arrange a plurality of openings these fin are installed, this just makes this LED lamp weight heavier, and material cost is high, and when user uses, feel is heavier, and this LED lamp assembling process is loaded down with trivial details, complex manufacturing technology, cannot provide production efficiency, is difficult to realize automated production.

Utility model content

In view of this, be necessary to provide a kind of lamp holder heat-dissipating LED ball bulb lamp of simple in structure and good heat dissipation effect.

A kind of lamp holder heat-dissipating LED ball bulb lamp, comprise LED light source, bulb housing and body, described LED light source is arranged on the top of this body, this bulb housing is ball cell-shell, this bulb housing is located at the top of this body, and this body inside is for solid construction and have metallic channel, and this body is made by high thermal conductivity coefficient material, described LED light source and this body are thermally coupled, and described LED light source is electrically connected to outside through this metallic channel by two wires.

Compared with prior art, this lamp holder heat-dissipating LED ball bulb lamp is arranged on LED light source at the top of body of solid construction thermally coupled with this body, because this body adopts high thermal conductivity coefficient material, make, so the heat that produces of LED light source can be delivered to outside by body and distributes.This lamp holder heat-dissipating LED ball bulb lamp is perfect heat-dissipating not only, and possesses simple outward appearance as incandescent lamp, does not need to take up room in addition a plurality of fin are set as prior art, so have advantages of simple in structure.

The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.

Fig. 1 is the front view of the lamp holder heat-dissipating LED ball bulb lamp 100 of the utility model the first embodiment.Please refer to Fig. 1 and Fig. 2, this lamp holder heat-dissipating LED ball bulb lamp 100 comprises LED light source 20, bulb housing 30, light source substrate 40, body 60 and ceramic insulation piece 70, these body 60 inside are for solid construction and have metallic channel 50, this LED light source 20 is arranged on this light source substrate 40, this light source substrate 40 is fixed on the top of this body 60, this ceramic insulation piece 70 is arranged on the bottom of this body 60, and this bulb housing 30 is located at the top of this body 60, in this LED light source 20 is housed in.

Please refer to Fig. 1, these body 60 inside are solid construction and are made by high thermal conductivity coefficient material, the top of this body 60 upwards protrudes out column 601 is set, this column 601 and this lamp holder 60 structure that is formed in one, the top of this body 60 is provided with heat transfer part 602, and this heat transfer part 602 is connected with the bottom opening of this bulb housing 30 by heat transfer glue.This body 60 outer setting lamp head shells and conducting end (not shown).These body 60 inside have two metallic channels 50, and these two wires are electrically connected to this lamp head shell and conducting end through these two metallic channels 50 respectively.These body 60 bottoms arrange ceramic insulation piece 70, and this ceramic insulation piece 70 comes this lamp head shell and conducting end are isolated, makes to insulate between this lamp head shell and this conducting end.This light source substrate 40 is fixed on the top of this column 601.

Please refer to Fig. 1, the integrated drive circuit (not shown) that is provided with on this light source substrate 40, this drive circuit carries out supplying with this LED light source 20 after rectification, filtering to supply current, and this LED light source 20 is electrically connected to outside through this metallic channel 50 by two wire (not shown).
