It should be noted that, because above-mentioned 2nd rete is directly fitted with described first rete, the heat absorbed from LED can be directly passed to described 2nd rete by so described first rete, this just requires that described 2nd rete has extremely high thermal conductivity, the heat absorbed from described first rete can be delivered to rapidly on described 2nd rete, in addition, also require that described 2nd rete has good heat dispersion simultaneously, and lower thermal expansivity.
Such as, the present invention provides a kind of matrix material for LED radiator, the 2nd rete wherein, it has thermal conductivity height, the advantage of perfect heat-dissipating and good mechanical property, so, when the heat absorbed from LED is directly passed to described 2nd rete by described first rete, the heat that so described first rete absorbs just can be delivered to rapidly on described 2nd rete, and in the process of heat conduction, based on the heat dispersion that described 2nd rete is excellent, it is also possible to the heat on described 2nd rete is lost in extraneous air. Secondly, owing to described 2nd rete is also in and the distance of LED relative close, the temperature of itself also can be higher, but, based on the thermal expansivity that described 2nd rete is lower, just can avoid producing gap between described 2nd rete and described third membrane layer, it is ensured that the compactness of both laminatings.
Such as, the matrix material for LED radiator of an embodiment of the present invention, the 2nd rete wherein, it comprises each component of following mass parts: Graphene 80 parts～95 parts, carbon nanotube 0.1 part～20 parts and carbon nano fiber 0.1 part～20 parts.
Above-mentioned 2nd rete is by adopting Graphene to be main raw material so that its thermal conductivity is greatly improved, and heat-conducting effect is better. In addition, then by adding carbon nanotube and carbon fiber, it is possible to forming heat dissipation channel, heat dispersion is also better.
It is emphasized that at this, owing to above-mentioned 2nd rete have employed the Graphene good material of this kind of conductive effect, therefore, the present invention is by described conductive layer and described first rete laminating, to isolate the circuit element of LED lamp inside, thus avoid described 2nd rete directly charged, and then improve the safety performance of the described matrix material for LED radiator, safety standard is higher.

It should be noted that, the heat produced because of LED luminescence is through first two layers, and namely after described first rete and described 2nd rete, the heat some is lost in extraneous air. In addition, owing to the cost of described 2nd rete is higher, its major cause is, the main raw material of described 2nd rete is the Graphene that preparation cost is higher, therefore, based on described third membrane layer heat transfer and heat radiation burden relatively little when, the heat dissipation metal material that described third membrane layer can use current market the most frequently used, to reach the effect reducing costs and obtaining better heat transfer property.
Such as, the present invention provides a kind of matrix material for LED radiator, third membrane layer wherein, it has thermal conductivity height, the advantage that perfect heat-dissipating, good mechanical property and cost are lower, so, when the heat of described 2nd rete passes to described third membrane layer, the heat that so described 2nd rete absorbs just can be delivered to more rapidly in described third membrane layer, and in the process of heat transfer, the heat of part can also be directly delivered in extraneous air by described third membrane layer.
