As to the further describing of above-mentioned oily cooling LED lamp, between described seal casinghousing and the outward flange of transparent lamp shade, be sealed with rubber ring.
The invention has the beneficial effects as follows: scribble coating in paper base plate extexine entirety, make whole paper base plate by coating uniformly transfer heat, heat radiation, reach paper base plate and extraneous paraffin oil electric insulation, the effect of sealing simultaneously; Use rubber ring to be fixed between seal casinghousing and transparent lamp shade edge, can make overall sealing property reach optimum; The paraffin oil of this structure seals after thermal expansion processing by carrying out after pouring into again, and makes inside be vacuum state, ensures that lamp body is in use safe and reliable; The paper base plate cost of this structure is low, can greatly improve radiating efficiency by oily radiating mode, has solved the difficulty of the LED lamp heat radiation of traditional use paper base plate making.
Brief description of the drawings
Fig. 1 is the structure chart of LED lamp.
Detailed description of the invention
The LED lamp manufacturing method of a kind of oily type of cooling of the present invention, 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, offer pouring orifice 6 at seal casinghousing 1, preferably, offer in the bottom of seal casinghousing 1.
B. paper base plate 3 entirety that are connected with lamp pearl 9 are immersed to clear coat solution, form clear coat (clear coating) 4, make clear coat 4 inside be sealing, electric insulation with the external world;
C. the paper base plate 3 that is coated with clear coat 4 is placed between transparent lamp shade 2 and seal casinghousing 1 and by paper base plate 3 and draws power interface outside seal casinghousing 1, sealing fixing described transparent lamp shade 2 and seal casinghousing 1;
D. inject paraffin oil 5 by pouring orifice 6 to seal casinghousing 1 inside, by power interface, the lamp pearl 9 of paper base plate 3 is continued to energising;
E. be warming up to while making paraffin oil 5 boiled until paper base plate 3, need the time to be about 4 hours.The described pouring orifice 6 of sealing immediately, cooled paraffin oil 5 forms vacuum in seal cavity.Vacuum space is now less, because the space that traditional fluid injection body mode leaves is larger, when in use, liquid flow space affects light compared with conference, therefore adopt this reperfusion mode can greatly reduce the space of leaving, heat is taken away for liquid flow in the space of leaving, and can ensure that in addition its space of leaving is vacuum state, preserves more favourable to liquid oil.
Further describing of the LED lamp manufacturing method of above-mentioned conduct to the above-mentioned oily type of cooling, on seal casinghousing 1 and paper base plate 3 through being coated with clear coat 4, offer installing hole 7 and interfix by installing hole 7, the edge of transparent lamp shade 2 and seal casinghousing 1 is sealed and interfixed by rubber ring 8.
As a kind of preferred version of the LED lamp manufacturing method of the above-mentioned oily type of cooling, the described boiled temperature of paraffin oil 5 be 90 degrees Celsius or more than.
Shown in Fig. 1, a kind of oily cooling LED lamp, comprise seal casinghousing 1, transparent lamp shade 2, paper base plate 3 and be arranged at the lamp pearl 9 on paper base plate 3, each paper base plate 3 surfaces are clear coat (clear coating) 4, this clear coat (clear coating) can be realized electric insulating effect, between seal casinghousing 1 and transparent lamp shade 2, be marked with paraffin oil 5, described coating 4 is by paper base plate 3 integral sealings and external insulation.
As to the further describing of above-mentioned oily cooling LED lamp, described seal casinghousing 1 is provided with the pouring orifice 6 that runs through seal casinghousing 1.
As to the further describing of above-mentioned oily cooling LED lamp, described seal casinghousing 1 and paper base plate 3 are located mutually by installing hole 7 is set.
As to the further describing of above-mentioned oily cooling LED lamp, 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, to the overall merit that the entirety of lamp plate has that contact area is high, the good and higher boiling of heat-conducting effect meets radiating efficiency, for common air heat radiation, there is its incomparable heat dispersion:
