It is appreciated that, owing to some described LED lamp bead are directly mounted at described heat sink, described heat sink bears bigger heat load, especially power and the higher situation of brightness requirement, therefore, it is necessary to improve the heat dispersion performance of described heat sink, in order to improve the heat dispersion of described heat sink further, the heat dispersion overall to improve described radiating lamp, such as, referring to Fig. 7, heat sink 500 includes the safe floor 510, heat-conducting layer 520, heat transfer layer 530 and the heat dissipating layer 540 that are cascading, and described LED lamp bead is arranged at described safe floor.

Such as, the described radiating lamp of one embodiment, its described safe floor includes each component of following mass parts: silicon nitride 80 parts～90 parts, titanium dioxide 30 parts～45 parts, silicon dioxide 2 parts～8 parts, Kaolin 2 parts～15 parts, light weight calcium 0.5 part～2 parts and rare earth oxide 0.2 part～0.5 part.Such as, described rare earth oxide includes in lanthana, cerium oxide, praseodymium oxide, europium oxide and terbia. Diterbium trioxide at least one, for instance, the mass ratio of lanthana, cerium oxide, praseodymium oxide, europium oxide and terbia. Diterbium trioxide is 1:1:1:1:1.

It is good that above-mentioned safe floor has insulation effect, the advantage that heat conductivity is big and thermal coefficient of expansion is low, so, when the heat of LED lamp bead is directly delivered to described safe floor, described safe floor quickly and in time by the heat that LED lamp bead near zone is assembled can be transferred to described heat-conducting layer, to guarantee the normal operation of LED lamp bead.Secondly, owing to described safe floor directly contacts or close together with LED lamp bead, the heat conduction load that it undertakes is maximum, above-mentioned safe floor uses silicon nitride as primary raw material, and mixed other materials can have relatively low thermal coefficient of expansion, such that it is able to avoid between described safe floor and described heat-conducting layer generation gap, and described safe floor self is avoided to produce gap, and then the problem that the heat conductivity produced after can avoiding this gap and gap filling air reduces.In addition, due to directly contacting or close together between described safe floor and LED lamp bead, it is susceptible to electric elements, wire directly with as described in safe floor situation about contacting, above-mentioned safe floor uses silicon nitride as primary raw material, and mixed other materials can have good insulating properties, such that it is able to avoid described safe floor to be energized, thus improve the security performance of described radiating lamp, safety standard is higher.

It should be noted that the heat produced because of described LED lamp bead luminescence is through front two-layer, namely after described safe floor and described heat-conducting layer, understand the heat loss of some in extraneous air.In addition, relatively costly due to described heat-conducting layer, it main reason is that, the primary raw material of described heat-conducting layer is the nano-graphene fiber that preparation cost is higher, therefore, based on described heat transfer layer heat transfer and heat radiation load relatively small when, described heat transfer layer can use the heat dissipation metal material that current market is more common, with reduce cost and obtain better heat transfer property effect.

Such as, the heat transfer layer of an embodiment of the present invention, it includes each component of following mass parts: copper 85 parts～90 parts, titanium 2 parts～4.5 parts, 0.1 part～0.3 part of nickel, 0.2 part～1.2 parts of magnesium, ferrum 0.2 part～0.7 part, vanadium 0.2 part～1.2 parts, 0.1 part～0.4 part of manganese and chromium 0.1 part～0.3 part.

Above-mentioned heat transfer layer adopts what the copper of 85 parts～90 parts can make heat transfer layer to have good heat transfer property, such that it is able to pass by the heat being transmitted on described heat-conducting layer more quickly, and then it is evenly dispersed in the structure that described heat transfer layer is overall, to prevent from heat contact position between described heat-conducting layer and described heat transfer layer accumulates, cause the generation of hot-spot phenomenon.In addition, above-mentioned heat transfer layer has heat conductivity height, perfect heat-dissipating, good mechanical property and lower-cost advantage, so, when the heat of described heat-conducting layer passes to described heat transfer layer, the heat that so described heat-conducting layer absorbs just can relatively rapidly be delivered in described heat radiation, and in the process of heat transfer, the heat of part can also be directly delivered in the air in the external world by described heat transfer layer.

It should be noted that, the heat produced when described LED lamp bead is through three first layers, namely respectively after described safe floor, described heat-conducting layer and described heat transfer layer, have relatively large a part of heat to be dissipated in transmission in air dielectric, in addition, owing to the primary raw material of described heat transfer layer is copper, its heavier mass, therefore, based on described heat dissipating layer dispel the heat load relatively small when, described heat dissipating layer can use radiating effect preferably, lighter in weight, lower-cost material, to reduce cost and weight, and obtain the effect of better heat dispersion.

Such as, the heat dissipating layer of an embodiment of the present invention, it includes each component of following mass parts: 70 parts～75 parts of aluminum, copper 35 parts～45 parts, 0.2 part～0.7 part of magnesium, 0.1 part～0.3 part of nickel, ferrum 0.2 part～0.7 part, 0.2 part～0.5 part of manganese, titanium 0.1 part～0.3 part, chromium 0.05 part～0.1 part and vanadium 0.1 part～0.3 part.

Above-mentioned heat dissipating layer adopts the aluminum of 70 parts～75 parts and the copper of 35 parts～45 parts, described heat dissipating layer can be made still to have good heat dispersion, such that it is able to guarantee that the heat passed over by described heat transfer layer can be dissipated in air dielectric by described heat dissipating layer rapidly, as, it is dissipated in inside described heat-dissipating cavity, and then avoid heat to pile up on described heat dissipating layer, cause hot-spot phenomenon to produce.Relative to prior art, merely adopting price costly and copper that quality is bigger, above-mentioned heat dissipating layer had both had good heat dissipation effect, can have again lighter weight rapidly by heat loss to air, is easily installed casting, advantage that price is less expensive.Meanwhile, relative to prior art, merely adopting the aluminium alloy that radiating effect is poor, above-mentioned heat dissipating layer has heat transfer property more preferably.

Such as, the thickness ratio of described safe floor, described heat-conducting layer, described heat transfer layer and described heat dissipating layer is 0.5～1.1:0.1～0.3:3～3.5:4～4.5, for optimizing the structure of described heat sink, is used for improving heat dispersion.
