Abstract
The utility model relates to LED lamp field, be specifically related to a kind of LED of the oily type of cooling, comprise seal casinghousing, transparent lamp shade, paper base plate and be arranged at the lamp pearl on paper base plate, each paper base plate surface is a clear coat, paraffin oil is marked with between seal casinghousing and transparent lamp shade, described coating by paper base plate integral sealing and and external insulation, described seal casinghousing is provided with the pouring orifice running through seal casinghousing, is sealed with rubber ring between seal casinghousing and the outward flange of transparent lamp shade.This structure scribbles coating in paper base plate extexine entirety, make whole paper base plate by coating uniform heat transfer, heat radiation, reach the paraffin oil electric insulation of paper base plate with the external world, the effect of sealing simultaneously, because paper base plate cost is low, greatly can improve radiating efficiency by oily radiating mode, solve the difficulty of the LED heat radiation that tradition uses paper base plate to make.
Description
Technical field
The utility model belongs to LED lamp field, is specifically related to a kind of radiator structure of LED.
Technical background
In the LED lamp structure of the current overwhelming majority, what it adopted is aluminium base, aluminium base has become the substrate material comparatively generally used, one of its reason obtaining significant market is good heat dispersion performance, but, along with the progress of environmental change and society, aluminium base has shown certain drawback, if modern society is for eco-friendly requirement, and the present situation that cost is high, in the prior art, use the structure of paper base plate to be applied to the market of low current and low cost more, it cannot be used for larger current domain, one of reason is that its radiating effect is not good.The mode solving heat radiation has multiple, the patent No. is 201020110603.4 disclose a kind of scheme using oil cooling but LED lamp power supply, under the requirement of power requirement good airproof performance, it has used cold oil instead to cool, but know based on these those skilled in the art, due to oil require rising-heat contracting-cold, therefore power source internal do not filled up and leave the space that heat rises; Though specifically do not mention that heat rises space, can easily learn, this space inserts air before not closing, then carry out sealing and formed.Moreover in technical scheme, a lot of details there is no fully open, result of use for reality cannot be known, as in actual use, if be filled directly into cold oil, insulating properties, electronic component will be caused to produce the not good problem of charing (carbonization), airtight performance.Meanwhile, the problem of integral sealing is not open yet.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of use oil cooling but, be applicable to the LED lamp structure that the paraffin oil of sealing state is in hot environment.
The LED of a kind of oily type of cooling described in the utility model, comprise seal casinghousing, transparent lamp shade, paper base plate and be arranged at the lamp pearl on paper base plate, each paper base plate surface is a transparent coating, be marked with paraffin oil between seal casinghousing and transparent lamp shade and form vacuum, described coating by paper base plate integral sealing and and external insulation.
As further describing of the LED to above-mentioned a kind of oily type of cooling, described seal casinghousing is provided with the pouring orifice running through seal casinghousing.
As further describing of the LED to above-mentioned a kind of oily type of cooling, described seal casinghousing and paper base plate are located mutually by arranging installing hole.
As further describing of the LED to above-mentioned a kind of oily type of cooling, between described seal casinghousing and the outward flange of transparent lamp shade, be sealed with rubber ring.
The beneficial effects of the utility model are: scribble coating in paper base plate extexine entirety, make whole paper base plate by coating uniform heat transfer, heat radiation, reach the paraffin oil electric insulation of paper base plate with the external world, the effect of sealing simultaneously; Use rubber ring to be fixed between seal casinghousing and transparent lamp shade edge, overall sealing property can be made to reach optimum; The paraffin oil of this structure seals after carrying out thermal expansion process after pouring into again, and makes inner in vacuum state, ensures that lamp body is in use safe and reliable; The paper base plate cost of this structure is low, greatly can improve radiating efficiency by oily radiating mode, solves the difficulty of the LED heat radiation that tradition uses paper base plate to make.
Accompanying drawing explanation
Fig. 1 is the structure chart of LED.
Detailed description of the invention
With reference to shown in Fig. 1, the LED of a kind of oily type of cooling described in the utility model, the lamp pearl 9 comprising seal casinghousing 1, transparent lamp shade 2, paper base plate 3 and be arranged on paper base plate 3, each paper base plate 3 surface is clear coat (clear coating) 4, this clear coat (clear coating) can realize electric insulating effect, be marked with paraffin oil 5 between seal casinghousing 1 and transparent lamp shade 2 and form vacuum, described coating 4 by paper base plate 3 integral sealing and and external insulation.
As further describing of the LED to the above-mentioned oily type of cooling, described seal casinghousing 1 is provided with the pouring orifice 6 running through seal casinghousing 1.
As further describing of the LED to the above-mentioned oily type of cooling, described seal casinghousing 1 and paper base plate 3 are located mutually by arranging installing hole 7.
As further describing of the LED to the above-mentioned oily type of cooling, between described seal casinghousing 1 and the outward flange of transparent lamp shade 2, be sealed with rubber ring 8.
The boiling point of this paraffin oil (paraffin oil) is 200 degrees Celsius, have that contact area is high to the entirety of lamp plate, overall merit that the good and higher boiling of heat-conducting effect meets radiating efficiency, for the heat radiation of common air, there is its incomparable heat dispersion.
The method manufacturing said structure is below provided, comprises the steps:
A. prepare seal casinghousing 1, transparent lamp shade 2 and be connected with the paper base plate 3 of lamp pearl 9, offering pouring orifice 6 at seal casinghousing 1, preferably, offer in the bottom of seal casinghousing 1.
Paper base plate 3 entirety that b. will be connected with lamp pearl 9 immerses clear coat solution, forms clear coat (clear coating) 4, make clear coat 4 inner and extraneous in sealing, electric insulation;
C. the paper base plate 3 being coated with clear coat 4 to be placed between transparent lamp shade 2 and seal casinghousing 1 and paper base plate 3 is drawn power interface outside seal casinghousing 1, the fixing described transparent lamp shade 2 of sealing and seal casinghousing 1;
D. inject paraffin oil 5 by pouring orifice 6 to seal casinghousing 1 inside, continue energising by the lamp pearl 9 of power interface to paper base plate 3;
E. until paper base plate 3 be warming up to make paraffin oil 5 boiled time, need the time to be about 4 hours.Close described pouring orifice 6 immediately, cooled paraffin oil 5 forms vacuum in seal cavity.Vacuum space is now less, the space left due to traditional note liquid mode is larger, when in use, liquid flow space comparatively conference affects light, therefore this reperfusion mode is adopted can to greatly reduce the space left, heat is taken away for liquid flow in the space left, and can ensure that its space left is vacuum state in addition, preserves advantageously liquid oil.
Seal casinghousing 1 with the paper base plate 3 through being coated with clear coat 4 offer installing hole 7 and is interfixed by installing hole 7, the edge of transparent lamp shade 2 and seal casinghousing 1 sealed by rubber ring 8 and interfixes.
The above not imposes any restrictions technical scope of the present utility model, all above embodiment is done according to the utility model technical spirit any amendment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
