Detailed description of the invention
Referring to figs. 1 through Fig. 3, a kind of water-proof LED lamp, including bonnet 1 and lampshade 5, in the space that described bonnet 1 and lampshade 5 are constituted, LED lamp panel 4 is installed, being provided with the drive circuit board 2 electrically connected with described LED lamp panel 4 with described bonnet 1 in the space that described LED lamp panel 4 is constituted, described bonnet 1 is provided with vacuum pipe joint 8 and the injected rubber hose joint 9 that the space constituted with described LED lamp panel 4 and described LED lamp panel 4 connects.
Described drive circuit board 2 is connected to 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 after described sealing shroud 7, and sealing shroud 7 is silica gel material, it is possible to preliminary gap between sealed guide inlet hole 6 and wire 10, when follow-up infusion epoxy resin, epoxy resin will 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 irrigating 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 will not spacing, be conducive to the conduction of heat.
It is filled with epoxy resin 12 in the space that described LED lamp panel 4 front and described lampshade 5 are constituted, in the space that described bonnet 1 and LED lamp panel 4 back side are constituted, is filled with heat conductive silica gel 11.Epoxy resin 12 seals, and heat conductive silica gel 11 seals and conductive force, makes LED realize good heat radiation when ensureing light transmittance, it is possible to increase the service life of product.
The manufacture method of above-mentioned water-proof LED lamp is as follows:
1, sealing shroud 7 is loaded in wire inlet hole 6, then by one end traverse sealing shroud 7 of wire 10, injection ring epoxy resins in bonnet, seal up the gap between wire 10 sealing shroud 7, wire inlet hole 6, stand according to ambient temperature and humidity and solidify 4-36 hour, at room temperature 25-30 degree, humidity about 50% stands and solidifies 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 adopt quick setting cement (such as 502, happy safe 406 etc.) 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, irrigate heat conductive silica gel, stand according to ambient temperature and humidity and solidify 1-12 hour, at room temperature 25-30 degree, humidity about 50% stands and solidifies 4 hours. The injection rate of heat conductive silica gel is advisable to fill full annular ring 3, will reserve the welding position of drive circuit board welding lead.
3, wire 10 is welded with drive circuit board 2, then in bonnet 1, irrigate heat conductive silica gel, and LED lamp panel 4 is seated, adopt the clampings such as fixture such as dovetail clip, stand according to ambient temperature and humidity and solidify 4-12 hour, at room temperature 25-30 degree, humidity about 50% stands and solidifies 4 hours. Heat conductive silica gel to fill bonnet, makes LED lamp panel 4, drive circuit board and silica gel be fully contacted, forms 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, makes lampshade 5 be formed with bonnet 1 and be tightly connected, stand according to ambient temperature and humidity and solidify 4-24 hour, at room temperature 25-30 degree, humidity about 50% stands and solidifies 8 hours.
5, on vacuum pipe joint 8 and injected rubber hose joint 9, vacuum tube and injected rubber hose are connected respectively, while vacuum tube evacuation, 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, standing according to ambient humidity and solidify 24-60 hours, at room temperature 20-25 degree, humidity about 50% stands and solidifies 48 hours.
In the solidification of step 1 to step 4, temperature and pressure etc. do not had special requirement. In steps of 5, owing to the groundwater increment of epoxy resin is big, and to be maintained with good light transmittance what seal, if solidification temperature is too high, solidification process react more violent, substantial amounts of heat can produce the disadvantageous factors of outward appearance such as bubble, wire drawing, crackle in the process of release, if solidification temperature is too low, extending the time of solidification, therefore, the present invention selects to stand under 20-25 degree Celsius of environment to solidify.
In steps of 5, injected rubber hose and vacuum tube are suitably transparent hose, can the perfusion situation of visual epoxy resin, after having irrigated, cut off injected rubber hose and vacuum tube, making the two length being connected on vacuum pipe joint 8 and injected rubber hose joint 9 respectively is 10-20cm, when standing solidification, temperature influence, epoxy resin volume in lampshade diminishes, and 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, the surface of metal and nonmetallic materials is had the adhesive strength of excellence by it, 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 employing Bole high-strength composite material company limited produces.
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, 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 Lycoperdon polymorphum Vitt thick liquid, B component is white viscous liquid, and two components can preserve for a long time before unmixed, has good insulating properties, elasticity, corrosion resistance and anti-flammability after solidification.
