Such as, the lighting of an embodiment of the present invention, wherein, and the described heat-sink shell of described heat radiation alloy, it comprises each component of following mass parts:
Copper 90 parts ~ 92 parts, 2 parts ~ 4.5 parts, aluminium, 1 part ~ 2.5 parts, magnesium, 0.5 part ~ 0.8 part, nickel, iron 0.1 part ~ 0.3 part, vanadium 1.5 parts ~ 4.5 parts, 0.1 part ~ 0.4 part, manganese, titanium 0.5 part ~ 0.8 part, chromium 0.5 part ~ 0.8 part, vanadium 0.5 part ~ 0.8 part, silicon 0.8 part ~ 15 parts and 0.5 part ~ 2 parts Graphenes.
First, what the copper (Cu) that above-mentioned heat-sink shell contains 90 parts ~ 92 parts can make heat-sink shell has the energy that absorbs heat preferably.When the mass parts of copper is 90 parts ~ 92 parts, the coefficient of heat conduction of heat-sink shell can reach more than 365W/mK, rapidly the heat that LED produces can be siphoned away, and then be dispersed in the structure of heat-sink shell entirety with making even heat, to prevent from the contact position of heat between LED and heat-sink shell accumulates, cause the generation of hot-spot phenomenon.And the density of heat-sink shell is less than the density of fine copper, effectively can alleviate the weight of heat-sink shell like this, be more conducive to manufacture is installed, also greatly reduce cost simultaneously.Wherein, the coefficient of heat conduction is defined as: per unit length, every K, can transmit the energy of how many W, unit is W/mK, and wherein " W " refers to thermal power unit, and " m " represents long measure rice, and " K " is absolute temperature units, the larger explanation heat absorption capacity of this numerical value is better.In addition, by adding the Graphene of 0.5 part ~ 2 parts, can effectively improve its coefficient of heat conduction, and then improving the heat absorption capacity of described heat-sink shell.
Secondly, heat-sink shell contain mass parts be 2 parts ~ 4.5 parts aluminium, the nickel of 1 part ~ 2.5 parts, 0.5 part ~ 0.8 part, magnesium, the iron of 0.1 part ~ 0.3 part, the vanadium of 1.5 parts ~ 4.5 parts, the manganese of 0.1 part ~ 0.4 part, the titanium of 0.5 part ~ 0.8 part, the chromium of 0.5 part ~ 0.8 part and the vanadium of vanadium 0.5 part ~ 0.8 part.Relative to fine copper material, the ductility of heat-sink shell, toughness, intensity and resistance to elevated temperatures improve all greatly, and not easy-sintering; Like this, when LED is installed on heat-sink shell, the high temperature that just can prevent LED from producing causes damage to heat-sink shell, and, there is good ductility, toughness and intensity heat-sink shell also can be prevented to be subject to excessive stresses when installing described LED and to cause distortion.Wherein, heat-sink shell contains the nickel (Ni) that mass parts is 0.5 part ~ 0.8 part, can improve the resistance to elevated temperatures of heat-sink shell.And for example, it is that the vanadium (V) of 1.5 parts ~ 4.5 parts can suppress heat-sink shell grain growth that heat-sink shell contains mass parts, obtains more tiny grain structure, to reduce the fragility of heat-sink shell, improve the mechanical property of heat-sink shell entirety, to improve toughness and intensity.And for example, heat-sink shell contains the titanium (Ti) that mass parts is 0.5 part ~ 0.8 part, can make the crystal grain miniaturization of heat-sink shell, to improve the ductility of heat-sink shell.
Finally, heat-sink shell also comprises the silicon (Si) that mass parts is 0.8 part ~ 15 parts, when heat-sink shell contains appropriate silicon, under the prerequisite not affecting heat-sink shell heat absorption capacity, can effectively promote hardness and the abrasion resistance of heat-sink shell.But, through repeatedly theory analysis and the discovery of experiment evidence, when the quality of silicon in heat-sink shell is too many, such as, when mass percent is more than more than 15 parts, the appearance distribution black particles of heat-sink shell can be made, and ductility reduces, and is unfavorable for the producing shaped of heat-sink shell.
Such as, the lighting of an embodiment of the present invention, wherein, and the described heat-conducting layer of described heat radiation alloy, it comprises each component of following mass parts:

Such as, the lighting of an embodiment of the present invention, wherein, and the described heat dissipating layer of described heat radiation alloy, it comprises each component of following mass parts:

First, above-mentioned heat dissipating layer contains the aluminium that mass parts is 88 parts ~ 93 parts, the coefficient of heat conduction of heat dissipating layer can be made to remain on 200W/mK ~ 220W/mK, when the heat of LED generation is after heat-sink shell and the heat radiation of heat-conducting layer part, when remaining heat passes to heat dissipating layer by heat-conducting layer again, heat dissipating layer can guarantee these remaining heats to be fallen apart by consistent, and then prevents heat from piling up on heat dissipating layer, causes hot-spot phenomenon.
Secondly, by adding the Graphene of 5 parts ~ 15 parts, effectively can improve the heat dispersion of described heat dissipating layer, and then the heat come from described heat-conducting layer transmission can be lost in extraneous air dielectric rapidly.
Finally, heat dissipating layer contains the vanadium that mass parts is the silicon of 5.5 parts ~ 10.5 parts, the magnesium of 0.3 part ~ 0.7 part, the copper of 0.05 part ~ 0.3 part, the iron of 0.2 part ~ 0.8 part, the manganese of 0.2 part ~ 0.5 part, the titanium of 0.05 part ~ 0.3 part, the chromium of 0.05 part ~ 0.1 part and 0.05 part ~ 0.3 part, greatly can improve the heat dispersion of heat dissipating layer.Such as, it is the silicon of 5.5 parts ~ 10.5 parts and the copper of 0.05 part ~ 0.3 part that heat dissipating layer contains mass parts, can guarantee that heat dissipating layer has the advantage of good mechanical properties and lighter weight, simultaneously, the heat-conductive characteristic of heat dissipating layer can also be improved further, guarantee that heat dissipating layer can fall apart by via the after-heat consistent after heat-sink shell and heat-conducting layer transmission further, and then prevent heat from piling up on heat dissipating layer, cause hot-spot phenomenon.
In order to improve the tensile strength of described heat dissipating layer further, such as, described heat dissipating layer also comprises the lead (Pb) that mass parts is 0.8 part ~ 1.2 parts, the lead containing 0.8 part ~ 1.2 parts when heat dissipating layer can improve the tensile strength of heat dissipating layer, like this, can prevent from striking out radiating fin when to be cast by heat dissipating layer, namely during laminated structure, pull stress owing to being subject to excessive punching press and rupturing.
In order to improve the high temperature oxidation resistance of described heat dissipating layer further, such as, described heat dissipating layer also comprises the niobium (Nb) that mass parts is 0.05 part ~ 0.08 part, when the mass parts of niobium is greater than 0.05 part, greatly can improve the antioxygenic property of heat dissipating layer, be appreciated that heat dissipating layer as in LED street lamp radiator with the parts that contacting external air area is maximum, its to high temperature oxidation resistance require higher.But, when the mass parts of niobium is greater than 0.08 part, the magnetic of heat dissipating layer can be caused sharply to increase, can the miscellaneous part in lighting be had an impact.
In order to improve the heat dispersion of described heat dissipating layer further, such as, heat dissipating layer also comprises the germanium (Ge) that mass parts is 0.05 part ~ 0.2 part, when the mass parts of germanium is greater than 0.05 part, good effect can be played to the raising of the heat dispersion of heat dissipating layer, but, when the quality accounting of germanium is too much, such as, when the mass parts of germanium is greater than 0.2 part, the brittleness of heat dissipating layer can be made again to increase.
Above-mentioned heat radiation alloy arranges described heat-sink shell, described heat-conducting layer and described heat dissipating layer by superposing successively, and the heat-conductive characteristic of described heat-sink shell, described heat-conducting layer and described heat dissipating layer successively decreases successively, define heat-conductive characteristic gradient, compared to fine copper material, under the prerequisite guaranteeing heat dispersion, weight greatly reduces; A large amount of aluminium alloy existed on market, heat dispersion greatly strengthens.
