Such as, the LED straight tube light fixture of an embodiment of the present invention, wherein, and the described heat-sink shell of described NEW TYPE OF COMPOSITE 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 sub-light source and OLED sub-light source produce can be siphoned away, and then be dispersed in the structure of heat-sink shell entirety with making even heat, to prevent heat from accumulating on LED sub-light source and the contact position between OLED sub-light source and heat-sink shell, 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 sub-light source and OLED sub-light source are installed on heat-sink shell, the high temperature that just can prevent LED sub-light source and OLED sub-light source from producing causes damage to heat-sink shell, further, having good ductility, toughness and intensity also can prevent heat-sink shell be subject to excessive stresses when installing described LED sub-light source and OLED sub-light source and 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 LED straight tube light fixture of an embodiment of the present invention, wherein, and the described heat-conducting layer of described NEW TYPE OF COMPOSITE heat radiation alloy, it comprises each component of following mass parts:
Copper 60 parts ~ 65 parts, 55 parts ~ 60 parts, aluminium, 0.8 part ~ 1.2 parts, magnesium, 0.2 part ~ 0.5 part, manganese, titanium 0.05 part ~ 0.3 part, chromium 0.05 part ~ 0.1 part, vanadium 0.05 part ~ 0.3 part, silicon 0.3 part ~ 0.5 part and Graphene 5 parts ~ 15 parts.
First, it is the copper of 60 parts ~ 65 parts and the aluminium of 55 parts ~ 60 parts that above-mentioned heat-conducting layer contains mass parts, the coefficient of heat conduction of heat-conducting layer can be made to remain on 320W/mK ~ 345W/mK, to ensure that the heat that the described LED sub-light source absorbed by heat-sink shell and OLED sub-light source produce can be passed to heat dissipating layer by heat-conducting layer rapidly, and then prevent heat from piling up on heat-conducting layer, cause hot-spot phenomenon to produce.Relative to prior art, merely adopt price costly and the larger copper of quality, above-mentioned heat-conducting layer both can ensure fast the heat of heat-sink shell to be passed to heat dissipating layer, there is again lighter weight, be convenient to install cast, advantage that price is cheaper.Meanwhile, relative to prior art, merely adopt the aluminium alloy that radiating effect is poor, above-mentioned heat-conducting layer has better heat transfer property.
Secondly, by adding the Graphene of 0.1 part ~ 0.3 part, greatly can improve the heat conductivility of described heat-conducting layer, better the heat passed over from heat-sink shell being passed to heat dissipating layer.
