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 are formed, LED lamp panel 4 is installed, be provided with the drive circuit board 2 be electrically connected with described LED lamp panel 4 in the space that described LED lamp panel 4 and described bonnet 1 are formed, described bonnet 1 is provided with the vacuum pipe joint 8 and injected rubber hose joint 9 that the space that forms with described LED lamp panel 4 and described LED lamp panel 4 is communicated with.
Described drive circuit board 2 is connected with the wire 10 stretched 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, one end of described wire 10 is welded with described drive circuit board 2 through after described sealing shroud 7, and sealing shroud 7 is silica gel material, can gap tentatively between sealed guide inlet hole 6 and wire 10, when 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 panel 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, when pouring into heat conductive silica gel, heat conductive silica gel can flow into below drive circuit board from glue feeding opening 13, make between LED lamp panel and drive circuit board can not spacing, be conducive to the conduction of heat.
Be filled with epoxy resin 12 in the space that described LED lamp panel 4 front and described lampshade 5 are formed, in the space that described bonnet 1 and LED lamp panel 4 back side are formed, be filled with heat conductive silica gel 11.Epoxy resin 12 seals, heat conductive silica gel 11 sealing and conductive force, making LED realize good heat radiation when ensureing light transmittance, can improve the service life of product.
The preparation method of above-mentioned water-proof LED lamp is as follows:
1, sealing shroud 7 is loaded 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 shroud 7, wire inlet hole 6, solidification 4-36 hour is left standstill according to environment temperature and humidity, at room temperature 25-30 degree, humidity about 50% leaves standstill solidification 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, quick setting cement (as 502, happy safe 406 etc.) is adopted by annular ring 3 to be pasted onto the back side of LED lamp panel 4, drive circuit board 2 is put into annular ring 3, then in annular ring 3, heat conductive silica gel is poured into, solidification 1-12 hour is left standstill according to environment temperature and humidity, at room temperature 25-30 degree, humidity about 50% leaves standstill solidification 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 is welded with drive circuit board 2, then in bonnet 1, heat conductive silica gel is poured into, and LED lamp panel 4 is seated, adopt fixture as clampings such as dovetail clips, solidification 4-12 hour is left standstill according to environment temperature and humidity, at room temperature 25-30 degree, humidity about 50% leaves standstill solidification 4 hours.Heat conductive silica gel will fill bonnet, makes LED lamp panel 4, drive circuit board fully contacts with silica gel, form good radiator.
4, the sidewall painting epoxy resin of lampshade 5 side is connected at bonnet 1, then lampshade 5 is assembled on bonnet 1, lampshade 5 and bonnet 1 is formed and is tightly connected, leave standstill solidification 4-24 hour according to environment temperature and humidity, at room temperature 25-30 degree, humidity about 50% leaves standstill solidification 8 hours.
5, on vacuum pipe joint 8 with injected rubber hose joint 9, vacuum tube and injected rubber hose is connected respectively, while vacuum tube vacuumizes, injected rubber hose injection ring epoxy resins, make in lampshade, injected rubber hose and vacuum tube, to fill full epoxy resin, then under 20-25 degree Celsius of environment, leave standstill solidification 24-60 hours according to ambient humidity, at room temperature 20-25 degree, humidity about 50% leaves standstill solidification 48 hours.
In the solidification of step 1 to step 4, special requirement be there is no to temperature and pressure etc.In steps of 5, because the groundwater increment of epoxy resin is large, and good light transmittance to be kept, if solidification temperature is too high while sealing, react more violent in solidification process, a large amount of heat can produce bubble, wire drawing, the disadvantageous factor of the outward appearances such as crackle in the process of release, if solidification temperature is too low, can extend the time of solidification, therefore, the present invention selects to leave standstill solidification under 20-25 degree Celsius of environment.
In steps of 5, injected rubber hose and vacuum tube are suitably transparent hose, can the perfusion situation of visual epoxy resin, after having poured into, cut off injected rubber hose and vacuum tube, the two length be connected in respectively on vacuum pipe joint 8 and injected rubber hose joint 9 is made to be 10-20cm, when standing solidification, 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, there is after solidification 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 Bole's high-strength composite material Co., Ltd produces is adopted.
Heat conductive silica gel is also guides thermalize compound conventional in current industry, there is good insulation, switching performance and pliability, in the present embodiment, adopt CS-9811G (A:B=1:1) the dual composition addition type flame-retarded heat-conducting organic silicon casting glue that apocalypse Science and Technology Ltd. of China of Shenzhen produces, component A is grey thick liquid, B component is white viscous liquid, and two components can be preserved for a long time before unmixed, have good insulating properties, elasticity, corrosion resistance and anti-flammability after solidification.
