Description
Technical field
The utility model relates to a kind of LED radiator, relates in particular to a kind of structure-integrated high-power LED radiator.
Background technology
As everyone knows, LED because its light efficiency is high, light decay is little, the life-span is long, the feature such as fast response time, shock resistance and environmental protection attracts tremendous attention, and also becomes just gradually light source of future generation simultaneously.But be accompanied by the extensive use of LED, and the continuous lifting of performance, the heat dissipation problem of great power LED comes out gradually, and becomes the principal element that affects LED service life and stability.
In recent years, the demand of high power LED package is moved towards slimming and cost gradually, and COB light source is with its low cost, and the advantages such as application portability and design variation are by being had an optimistic view of in market.Solution that now on market, popular employing COB technology solves great power LED cooling problem and that adopt is, that LED chip is directly encapsulated in aluminium base plane, packaged chip is directly fixed on the radiator of the aluminium base or aluminium section bar of die casting with screw again, there is a point to become a face, disperse the heat radiation of chip, greatly improved the heat dissipation problem of great power LED, and it is high to have light efficiency, is easy to the advantages such as luminous intensity distribution.
Show according to senior engineer LED industrial research institute investigation report, within 2010, the prominent example that becomes global LED illumination is expanded in Japanese LED bulb market comprehensively.Current Japanese LED bulb lamp market mainly transfers to COB polycrystalline and is encapsulated as master, and traditional high-power chip and module are used for greatly the directive property light sources such as MR16.Although COB encapsulation has improved the heat dissipation problem of great power LED, the contact area between aluminium base and radiator is little, and empty resistance is large, and radiating effect still exists very large room for promotion; Owing to being area source, therefore part light has finally been fallen by absorbed inside owing to having there is total reflection in the horizontal direction, thereby also can cause light extraction efficiency poor simultaneously.
Utility model content
The purpose of this utility model is the deficiency in order to solve the problems of the technologies described above existence, provide a kind of optical efficiency high, radiating effect is better, processing and more simple and fast of production procedure, the while also utilizes heat spreader structures cleverly for lens are laid the structure-integrated high-power LED radiator that more appropriate position is provided.
For achieving the above object, technical problem of the present utility model is mainly solved by the following technical programs: a kind of structure-integrated high-power LED radiating structure of the COB of employing encapsulation technology, choose and there is certain thickness aluminium sheet and encapsulate required aluminium base as carrying out COB, aluminium base thickness is according to concrete actual conditions and different, but all should meet the demand of following integrated processing.The aluminium base of cuboid is carried out to integrated being cast into " to return " after word shape, top by cutting processing at aluminium base, the any place that is less than the interior rectangle length of side cuts away an isosceles inverted trapezoidal, obtain the special-shaped slot shape aluminium base that a upper end is open isosceles inverted trapezoidal, the random length of isosceles inverted trapezoidal is all less than the length of bottom land inside, have air vent and directly-heated pipe through hole at the same plane of bottom land, air vent and directly-heated pipe through hole cross-distribution.This structure-integrated high-power LED radiator of the present invention, comprise that 10 above identical this upper ends are open isosceles inverted trapezoidal, the random length of isosceles inverted trapezoidal is all less than the special-shaped slot shape aluminium base of the length of bottom land inside, at the bottom of special-shaped slot, be provided with air vent and directly-heated pipe through hole, air vent and directly-heated pipe through hole cross-distribution, directly-heated pipe runs through these special-shaped slot shape aluminium bases by through hole, being processed into screw thread at the end of directly-heated pipe and head end fixes by nut, LED chip is directly encapsulated in the aluminium base encapsulation plane of multiple bottom lands formation.
Technical solutions of the utility model can also further be optimized according to actual conditions: can be provided with air vent in the both sides of special-shaped slot shape aluminium base, or embed directly-heated pipe, make all to obtain very high heat conduction efficiency in multiple directions.
In the utility model, aluminium base is made by integrated casting forming, and with respect to independently radiator and aluminium base, thermal resistance further reduces, and has also shortened heat-dissipating distance when improving area of dissipation to a great extent; In addition utilized directly-heated pipe in gas-liquid change procedure, through pervaporation and condensation transferring heat, there is high heat-transfer effect, and more small heat pipe length is shorter to have advantages of volume compared with common curved heat pipe.Therefore this utility model has improved greatly radiating efficiency in limited space.
The utility model has also been simplified the processing and the production procedure that adopt the high-power LED lamp of COB encapsulation technology, and integrated die casting also makes to have had more fastening stable structure, has shortened to a certain extent installation time and manpower.
Because the area source light extraction efficiency that COB encapsulation forms is poor, therefore often need to increase lens and carry light efficiency, and the utility model is also for the installation of lens is provided convenience---the installation that is lens at the isosceles inverted trapezoidal place of special-shaped slot shape aluminium base provides a supporting structure, a supporting structure is installed at isosceles inverted trapezoidal place at special-shaped slot shape aluminium base, and lens are fixed in support.When mounted lens, only need design lens size according to the distance of both sides fin and shape, then lens are placed in to this part fin of separation both sides, encapsulation region and the inverted trapezoidal region that horizontal plane forms.
In the utility model, supporting structure required when COB encapsulates required aluminium base, radiating fin and mounted lens forms by integrated die casting, therefore the processing and the production procedure that adopt the high-power LED lamp of COB encapsulation technology have been simplified, integrated die casting also makes to have had more fastening stable structure, has shortened to a certain extent installation time and manpower.
