The major technique of LED lamp box is exactly a LGP, briefly be exactly on optical grade acrylic (lucite) flat board with the high reflectance and the material of extinction not, stamp circular or square diffusion point at bottom surface of light guide plate with laser engraving machine; When light is mapped to the diffusion point from the side; Emission light can destroy launching condition and penetrate by LGP is positive toward all angles diffusions then, utilizes various densitys, diffusion point not of uniform size; Can make the LGP uniformly light-emitting; Become " face " luminous the side luminescent conversion, in adding the light reflected back LGP that expelling plate exposes the bottom surface, be used for improving the service efficiency of light.
Existing multilayer complex films reflecting plate comprises: a laminar substrate and one deck reflector material, base material and reflector material are through glue bond.But reflecting plate is many works under hot environment, and the easy deformation of being heated influences the operate as normal of LGP.
High, the not yielding and composite membrane reflecting plate cheaply of rate of heat dissipation when therefore, needing that exploitation is a kind of works under hot conditions.
Summary of the invention
The goal of the invention of the utility model provides a kind of high heat conduction composite membrane reflecting plate, and through the improvement of structure, the reflecting plate cost is low, rate of heat dissipation is high, and is not yielding when under hot conditions, working.
For reaching the foregoing invention purpose; The technical scheme that the utility model adopts is: a kind of high heat conduction composite membrane reflecting plate; Comprise radiating base layer, reflecting layer and be located at radiating base layer and the reflecting layer between, with two-layer compound tack coat, be casually arranged with heat conduction particle in the said tack coat.
The recombination process and the operation principle of the utility model are following: the tack coat that one deck contains heat conduction particle is set on radiating base layer, then the reflecting layer is bonded on the tack coat, be combined into the multilayer complex films reflecting plate.When under hot conditions, working, the heat conduction and heat radiation property of tack coat that contains heat conduction particle is good, and reflecting plate can not deform, working stability.
In the preceding text, the material of said tack coat is silica gel or acrylic glue etc.The heat conducting nano particle of said heat conduction particle for constituting by aluminum nitride particle.But be not limited to aluminum nitride particle, can also use particles such as carborundum, boron nitride, aluminium oxide.
Further technical scheme, the thickness of said tack coat is 0.005 ~ 0.01mm, and the particle diameter of said heat conduction particle is 20 ~ 25nm, and the number of the said heat conduction particle that is casually arranged with in every square centimeter the tack coat is 1 * 10
6~ 8 * 10
6
The number of the said heat conduction particle that preferably, is casually arranged with in every square centimeter the tack coat is 3 * 10
6~ 6 * 10
6
In the technique scheme, said radiating base layer is made up of aluminium foil.Radiating base layer is selected aluminium foil for use, in heat conduction and heat radiation, plays shielding action, and anti-interference is good.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
1. be casually arranged with the heat conducting nano particulate in the tack coat of the utility model, like particles such as aluminium nitride, carborundum, the heat conduction and heat radiation performance is good, deforms when avoiding reflecting plate under hot conditions, to work.
2. the radiating base layer material selection aluminium foil of the utility model, heat conduction and heat radiation property is good, plays shielding action simultaneously, and anti-interference is good.
3. the utility model just increases heat conduction particle in tack coat on the basis of existing composite membrane reflecting plate, and is simple in structure, easy to process, cost is low.
