In order to strengthen the cooperation thermolysis between heat-conducting part 100, heat transfer part 200 and radiating part 300, the heat better LED lamp being produced falls apart.For example, heat-conducting part 100 and heat transfer part 200 structure that is formed in one.And for example, heat transfer part 200 and radiating part 300 structure that is formed in one.And for example, heat-conducting part 100, heat transfer part 200 and radiating part 300 structure that is formed in one.Like this, can strengthen the cooperation thermolysis between heat-conducting part 100, heat transfer part 200 and radiating part 300, the heat better LED lamp being produced falls apart.
In order to strengthen the cooperation thermolysis between heat-conducting part 100, heat transfer part 200 and radiating part 300, the heat better LED lamp being produced falls apart.For example, on heat-conducting part 100, heat transfer part 200 and radiating part 300, all offer through hole (not shown), by screw element firmware (not shown), wear heat-conducting part 100, heat transfer part 200 and radiating part 300 and heat-conducting part 100, heat transfer part 200 and radiating part 300 are connected as one.And for example, in the junction of heat-conducting part 100, heat transfer part 200 and radiating part 300, apply silica gel, to improve radiating effect.Like this, can strengthen the cooperation thermolysis between heat-conducting part 100, heat transfer part 200 and radiating part 300, the heat better LED lamp being produced falls apart.
For example, the thickness of heat-conducting part 100 is 1mm～2mm, and the thickness of radiating part 200 is 3mm～5mm, and the thickness of radiating part is 15mm～20mm.And for example, radiating part arranges several radiating fins, and the air described in several between radiating fin is split to form between several small radiating areas, and described in several, radiating fin can increase cooling surface area, to increase the coefficient of heat conduction, and then further strengthen radiating effect.
Above-mentioned LED lamp radiator is by arranging heat-conducting part, heat transfer part and the radiating part of order close contact, and, the heat-conductive characteristic of heat-conducting part, heat transfer part and radiating part successively decreases successively, formed heat-conductive characteristic gradient, thereby further optimized the heat dissipation path of LED lamp radiator, greatly improve the heat dispersion of LED lamp radiator, can meet the radiating requirements of the LED lamp that caloric value is large.With respect to simple copper alloy, above-mentioned LED lamp heatsink mass is lighter, and cost is lower.With respect to simple aluminium alloy, the heat dispersion of above-mentioned LED lamp radiator is more excellent.
For example, the heat-conducting part of an embodiment, it comprises each component of following mass parts:
0.1 part～0.3 part of 93 parts～97 parts of copper, 2 parts～4.5 parts, aluminium, 0.1 part～0.3 part, nickel, 0.2 part～1.2 parts of vanadium, 0.1 part～0.4 part, manganese, 0.1 part～0.3 part of titanium, 0.1 part～0.3 part of chromium and vanadium.
Above-mentioned heat-conducting part contains copper (Cu) can make the heat conductivility of heat-conducting part remain on a higher level.When the mass parts of copper is 93 parts～97 parts, more than the coefficient of heat conduction of heat-conducting part can reach 380W/mK, the heat that can rapidly LED lamp be produced siphons away, and then be evenly dispersed in the structure of heat-conducting part integral body, to prevent that heat from accumulating on the contact position between LED lamp and heat-conducting part, causes the generation of hot-spot phenomenon.And the density of heat-conducting part but only has 8.0kg/m
3～8.1kg/m
3, be far smaller than the density of fine copper, can effectively alleviate like this weight of heat-conducting part, be more conducive to install and manufacture, also greatly reduced 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 unit, the larger explanation heat conductivility of this numerical value is better.

For example, heat-conducting part also comprises that mass parts is the silicon (Si) of 1 part～2.5 parts, when heat-conducting part contains appropriate silicon, can not affect under the prerequisite of heat-conducting part heat conductivility, effectively promotes hardness and the abrasion resistance of heat-conducting part.But, through theory analysis repeatedly and experiment evidence, find, in heat-conducting part, the quality of silicon is too many, and for example mass percent surpasses 15 parts when above, can make the appearance distribution black particles of heat-conducting part, and ductility reduces, and is unfavorable for the production moulding of heat-conducting part.

And for example, the heat-conducting part of an embodiment, it comprises each component of following mass parts:
0.3 part of 97 parts of copper, 4.5 parts, aluminium, 0.3 part, nickel, 1.2 parts of vanadium, 0.4 part, manganese, 0.3 part of titanium, 0.3 part of chromium and vanadium.
And for example, the heat-conducting part of an embodiment, it comprises each component of following mass parts:
1 part of 93 parts of copper, 2 parts, aluminium, 0.1 part, nickel, 0.2 part of vanadium, 0.1 part, manganese, 0.1 part of titanium, 0.1 part of chromium, 0.1 part of vanadium and silicon.
And for example, the heat-conducting part of an embodiment, it comprises each component of following mass parts:
2 parts of 95 parts of copper, 3.5 parts, aluminium, 0.2 part, nickel, 0.8 part of vanadium, 0.3 part, manganese, 0.2 part of titanium, 0.2 part of chromium, 0.2 part of vanadium and silicon.

It is the copper of 45 parts～52 parts and the aluminium of 47 parts～54 parts that above-mentioned heat transfer part contains mass parts, can be so that the coefficient of heat conduction of heat transfer part remains on 300W/mK～350W/mK, to guarantee that the heat that heat transfer part can produce the LED lamp being absorbed by heat-conducting part passes to radiating part rapidly, and then prevent that heat from piling up on heat transfer part, cause hot-spot phenomenon to produce.With respect to prior art, merely adopt the copper that price is more expensive and quality is larger, above-mentioned heat transfer part both can guarantee fast the heat of heat-conducting part to be passed to radiating part, had advantages of again lighter weight, was convenient to install casting, price is cheaper.Meanwhile, with respect to prior art, merely adopt the poor aluminium alloy of radiating effect, above-mentioned heat transfer part has better heat transfer property.
In addition, it is the magnesium of 0.3 part～0.7 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 the vanadium of 0.05 part～0.3 part that heat transfer part contains mass parts, has improved yield strength, tensile strength and the resistance to elevated temperatures of heat transfer part.For example, through many experiments evidence and theory analysis, find, it is the magnesium of 0.3 part～0.7 part that heat transfer part contains mass parts, can give to a certain extent heat transfer part yield strength and tensile strength, because above-mentioned LED lamp radiator is in manufacture process, need to the whole punching press of heat-conducting part, heat transfer part and radiating part is one-body molded, this just needs radiating part to have stronger yield strength, to prevent that radiating part is subject to excessive punching press stress and produces non-reversible deformation in process, and then guarantee the normal heat dispersion of above-mentioned LED lamp radiator.When the relative mass of magnesium is too low, for example, when mass parts is less than 0.3 part, can not fully guarantee that the yield strength of heat transfer part meets the demands, yet, when the relative mass of magnesium is too high, for example, when mass parts is greater than 0.7 part, can make again the ductility of heat transfer part and heat conductivility decline rapidly.For example, it is the iron of 0.2 part～0.8 part that heat transfer part contains mass parts, can give resistance to elevated temperatures and high temperature resistant mechanical performance that heat transfer part is higher, is beneficial to the processing casting of heat transfer part.
For example, the heat transfer part of an embodiment, it comprises each component of following mass parts:
