Moreover, the LED lamp radiating module has the advantages of simple structure, long service life, and high economical and practical value.

Description

LED lamp radiating module

Technical field

The utility model relates to a kind of lighting, refers to a kind of quick heat radiating module of LED lamp especially.

Background technology

As everyone knows, light emitting diode is to utilize electric energy to be converted into the principle of luminous energy, in two terminals of semiconductor both positive and negative polarity, apply voltage, when electric current passes through, electronics is combined with electric hole, dump energy just discharges with the form of light, rely on the difference of the material that uses, height with its energy makes photon energy produce the light of different wave length, have the brightness height, save advantage electric, that the life-span is long, thereby be widely used in becoming the indispensable articles for use of common people's lighting apparatus in production, the various fields in life.

But the technology of this traditional LED lamp in the use, the power of actual input only has 15 ~ 20% to convert light to, all the other 80 ~ 85% convert heat to, and these heat are if discharge in good time, can make that the crystal grain boundary Yin Wendu of LED is too high and directly influence luminous efficiency and luminescent lifetime.And in the use, the LED of high power, high brightness illumination, whether its residing space and position well play great key effect equally to heat radiation.

Summary of the invention

For overcoming the defective of above-mentioned existence, the utility model provides a kind of radiating rate fast, effective LED lamp radiating module.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED lamp radiating module, by the LED lamp, circuit board, radiating fin and heat conduction copper post are formed, wherein be provided with thermal grease in the middle of LED lamp and the circuit board, between the shrinkage pool of heat conduction copper post and radiating fin, be filled with thermal grease equally, the LED lamp places the circuit board below and contacts with heat conduction copper post, circuit board is provided with a hole at the link position place of LED lamp, radiating fin is provided with a shrinkage pool at the hole place that is positioned at circuit board, heat conduction copper post is T type shape, and its T shape end face is arranged in the hole of circuit board and is attached at the shrinkage pool end limit of radiating fin.

LED lamp radiating module of the present utility model has simple in structure, characteristics easy to use, owing to used the heat conduction copper post that is T type shape, reduced the error that processing and assembling are produced, made things convenient for the position of going into of each parts to connect, and the LED lamp directly is arranged on the T shape end of heat conduction copper post, be directly delivered on the radiating fin by heat energy and dispel the heat the LED lamp, thereby avoided tradition with the shortcoming of metallic circuit as heat-conducting medium, in addition, the utility model is between T shape end and LED lamp, and be provided with thermal grease between heat conduction copper post and the shrinkage pool, in order to add the efficient that heat-flash transmits, make the efficient of quick heat radiating further improve, on the other hand, also can reduce the cost of metallic circuit board using material.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of traditional LED lamp;

Fig. 2 is a structural representation of the present utility model.

The specific embodiment

In conjunction with shown in Figure 1, it is traditional LED lamp module, comprise LED lamp 1, metallic circuit 2, radiating fin 3 and thermal grease 4, by LED lamp 1 is connected on the metallic circuit 2, metallic circuit 2 then directly is attached on the radiating fin 3, Ji Qiuneng is delivered to the heat that LED lamp 1 is come out on the radiating fin 3 fast and directly, and by radiating fin 3 to reach the purpose of heat radiation, though this type of way can take the heat that LED lamp 1 distributes and be dispersed in the air out of and go, but its effect is very limited, reason is the conductivity of the heat generation rate of LED lamp 1 greater than metallic circuit 2, and metallic circuit 2 is by one deck conductive layer 21,

insulating barrier

22 and 23 Group of heat radiation heat transfer layer become, and the transmission of insulating barrier 22 a Ge Right heat itself is limited, although how good the effect of Hot fin 3 is so loose, but be subject to the influence of insulating barrier 22, so LED lamp 1 can't reach the requirement of expection heat radiation, and can be slow because of insulating barrier 22 coefficients of overall heat transmission of metallic circuit 2, make the illumination heat energy of LED lamp 1 inside constantly put aside, cause constantly decay and successively decreasing service life of LED lamp 1 brightness.

In conjunction with shown in Figure 2, LED lamp radiating module of the present utility model, by LED lamp 1, circuit board 2, radiating fin 3 and heat conduction copper post 5 are formed, wherein be provided with thermal greases 4 in the middle of LED lamp 1 and the circuit board 2, LED lamp 1 places the below of circuit board 2 and contacts with heat conduction copper post 5, circuit board 2 is provided with a hole 21 at the link position of LED lamp 1, radiating fin 3 is provided with a shrinkage pool 31 at hole 21 places that are positioned at circuit board 2, heat conduction copper post 5 is T type shape and is provided with T shape end face 51, and its T shape end face 51 is arranged in the hole 21 of circuit board 2 and is attached at the shrinkage pool 31 end limits of radiating fin 3.

The cylinder 52 of heat conduction copper post 5 goes into to be positioned at radiating fin 3 by shrinkage pool 31, and be filled with thermal grease 4 between cylinder 52 and the shrinkage pool 31, LED lamp 1 is positioned on the T shape end face 51, be provided with thermal grease 4 therebetween equally, thus, the heat energy that just LED lamp 1 can be come out directly is delivered on the radiating fin 3 by heat transfer copper post 5 and distributes.

Characteristics of the present utility model also are: the heat that the LED lamp gives out, be positioned at radiating fin 3 by heat conduction copper post 5, and can shorten the distance 6,7 of LED lamp and radiating fin 3 peripheral radiating surfaces equally, the distance of heat transfer shortens, and nature can increase the speed that heat is transmitted.

For reaching heat dispersion preferably, heat conduction copper post 5 may be selected to be copper product, because of it has high-termal conductivity, radiating fin 3 is good with aluminum products then, because of aluminium has the characteristic of high heat radiation, both match, and can obtain the requirement of LED lamp high cooling efficiency, have higher utility and market prospects, but large tracts of land is promoted and is used.

The foregoing description is only enumerated for explanation the utility model, is not to be used to limit the utility model, and the structure of any effects equivalent based on the conversion of the technical program institute all belongs to protection domain of the present utility model.
