Detailed description of the invention
Referring to figs. 1 through Fig. 3, a kind of water-proof LED lamp, comprise bonnet 1 and lampshade 5, in the space that described bonnet 1 and lampshade 5 form, LED lamp plate 4 is installed, in the space that described LED lamp plate 4 forms with described bonnet 1, the drive circuit board 2 being electrically connected with described LED lamp plate 4 is installed, described bonnet 1 is provided with vacuum pipe joint 8 and the injected rubber hose joint 9 that the space that forms with described LED lamp plate 4 and described LED lamp plate 4 is communicated with.
Described drive circuit board 2 is connected with the wire 10 stretching out outside described bonnet 1, specifically, described bonnet 1 is provided with wire inlet hole 6, in described wire inlet hole 6, sealing shroud 7 is installed, weld with described drive circuit board 2 through described sealing shroud 7 is rear one end of described wire 10, and sealing shroud 7 is silica gel material, tentatively the gap between sealed guide inlet hole 6 and wire 10, in follow-up infusion epoxy resin, epoxy resin can not flow out from the gap between wire inlet hole 6 and wire 10.
The rear side of described LED lamp plate 4 is pasted with an annular ring 3, described drive circuit board 2 adopts heat conductive silica gel to be encapsulated in annular ring 3, described drive circuit board 2 is provided with glue feeding opening 13, in the time of perfusion heat conductive silica gel, heat conductive silica gel can flow into drive circuit board below from glue feeding opening 13, make between LED lamp plate and drive circuit board can spacing, be conducive to the conduction of heat.
In the space that described LED lamp plate 4 is positive and described lampshade 5 forms, be filled with epoxy resin 12, in the space that described bonnet 1 and LED lamp plate 4 back sides form, be filled with heat conductive silica gel 11. Epoxy resin 12 seals, and 11 sealings of heat conductive silica gel and conductive force make LED lamp in the situation that ensureing light transmittance, realize good heat radiation, the service life that can improve product.
The preparation method of above-mentioned water-proof LED lamp is as follows:
1, sealing shroud 7 is packed in wire inlet hole 6, then sealing shroud 7 is passed in one end of wire 10, injection ring epoxy resins in bonnet, seal up the gap between wire 10 sealing shrouds 7, wire inlet hole 6, leave standstill curing 4-36 hour according to environment temperature and humidity, at room temperature 25-30 degree, humidity 50% left and right leaves standstill solidifies about 24 hours. The groundwater increment of epoxy resin is unsuitable too many, is advisable can seal up gap between wire 10, sealing shroud 7, wire inlet hole 6.
2, annular ring 3 is adopted quick setting cement (as 502, happy safe 406 etc.) stick on the back side of LED lamp plate 4, drive circuit board 2 is put into annular ring 3, then at the interior perfusion heat conductive silica gel of annular ring 3, leave standstill curing 1-12 hour according to environment temperature and humidity, at room temperature 25-30 degree, humidity 50% left and right leaves standstill solidifies about 4 hours. The injection rate of heat conductive silica gel is advisable to fill full annular ring 3, reserve the welding position of drive circuit board welding lead.
3, wire 10 and drive circuit board 2 are welded, then at the interior perfusion heat conductive silica gel of bonnet 1, and LED lamp plate 4 is seated, adopt fixture as clampings such as dovetail clips, leave standstill curing 4-12 hour according to environment temperature and humidity, at room temperature 25-30 degree, humidity 50% left and right leaves standstill solidifies about 4 hours. Heat conductive silica gel will be filled bonnet, and LED lamp plate 4, drive circuit board are fully contacted with silica gel, forms good radiator.
4, connect the sidewall painting epoxy resin of lampshade 5 one sides at bonnet 1, then lampshade 5 is assembled on bonnet 1, makes lampshade 5 form and be tightly connected with bonnet 1, leave standstill curing 4-24 hour according to environment temperature and humidity, at room temperature 25-30 degree, humidity 50% left and right leaves standstill solidifies about 8 hours.
5, be connected respectively vacuum tube and injected rubber hose at vacuum pipe joint 8 with on injected rubber hose joint 9, when vacuum tube vacuumizes, injected rubber hose injection ring epoxy resins, make the full epoxy resin of filling in lampshade, injected rubber hose and vacuum tube, then under 20-25 degree Celsius of environment, leave standstill and solidify about 24-60 hour according to ambient humidity, at room temperature 20-25 degree, humidity 50% left and right leaves standstill solidifies about 48 hours.
Step 1 to step 4 solidify in, temperature and pressure etc. is not had to special requirement. In step 5, because the groundwater increment of epoxy resin is large, and in sealing, keep good light transmittance, if solidification temperature is too high, in solidification process, reaction is more violent, a large amount of heat can produce bubble, wire drawing, the disadvantageous factor of the outward appearances such as crackle in the process discharging, if solidification temperature is too low, can extend the curing time, therefore, the present invention is chosen under 20-25 degree Celsius of environment and leaves standstill and solidify.
In step 5, injected rubber hose and vacuum tube are suitably transparent hose, perfusion situation that can visual epoxy resin, after having poured into, cut off injected rubber hose and vacuum tube, the length that the two is connected in respectively on vacuum pipe joint 8 and injected rubber hose joint 9 is 10-20cm, in the time of standing solidifying, temperature influence, epoxy resin smaller volume in lampshade, the epoxy resin of vacuum pipe joint 8 and injected rubber hose joint 9 can add in lampshade, makes not interspace and bubble in lampshade, after having solidified, cut off injected rubber hose and vacuum tube.
Epoxy resin is a kind of encapsulant conventional in current industry, after solidifying, there is good physics, chemical property, it has excellent adhesive strength to the surface of metal and nonmetallic materials, dielectric properties are good, set shrinkage factor is little, and hardness is high, and pliability is better, in the present embodiment, the 500AB-307 type epoxide-resin glue that adopts Bole's high-strength composite material Co., Ltd to produce.
Heat conductive silica gel is also heat conduction compound conventional in current industry, there is good insulation, switching performance and pliability, in the present embodiment, CS-9811G (A:B=1:1) the dual composition addition type flame-retarded heat-conducting organic silicon casting glue that adopts apocalypse Science and Technology Ltd. of China of Shenzhen to produce, A component is grey thick liquid, B component is white thick liquid, and two components can be preserved for a long time before unmixed, after solidifying, has good insulating properties, elasticity, corrosion resistance and anti-flammability.
