For example, the bar shaped body of an embodiment, it comprises each component of following mass parts:
1 part~2.5 parts of 95 parts~96.5 parts of copper, 2 parts~3.2 parts, aluminium, 0.2 part~0.25 part, magnesium, 0.4 part~0.9 part of iron, 0.2 part~0.3 part, manganese, 0.2 part~0.3 part of titanium, 0.1 part~0.2 part of chromium, 0.1 part~0.2 part of vanadium and silicon.
For example, the bar shaped body of an embodiment, it comprises each component of following mass parts:
0.1 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 and vanadium.
And for example, the bar shaped body of an embodiment, it comprises each component of following mass parts:
0.2 part 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, 0.2 part of titanium and vanadium.
And for example, the bar shaped body 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 bar shaped body 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 bar shaped body 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.
And for example, the bar shaped body of an embodiment, it comprises each component of following mass parts:
2.5 parts 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, 0.3 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 by bar shaped bulk absorption 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 bar shaped body 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 assembly type bar shaped radiator is in manufacture process, need to the whole punching press of bar shaped body, 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 assembly type bar shaped 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:
0.1 part~0.3 part of 47 parts~50 parts of copper, 49 parts~52 parts, aluminium, 0.2 part~0.7 part, magnesium, 0.2 part~0.7 part of iron, 0.2 part~0.5 part, manganese, 0.1 part~0.3 part of titanium, 0.05 part~0.1 part of chromium and vanadium.
For example, the heat transfer part of an embodiment, it comprises each component of following mass parts:
0.05 part of 45 parts of copper, 47 parts, aluminium, 0.3 part, magnesium, 0.2 part of iron, 0.2 part, manganese, 0.05 part of titanium, 0.05 part of chromium and vanadium.
And for example, the heat transfer part of an embodiment, it comprises each component of following mass parts:
0.2 part of 50 parts of copper, 48 parts, aluminium, 0.5 part, magnesium, 0.6 part of iron, 0.4 part, manganese, 0.2 part of titanium, 0.08 part of chromium and vanadium.
And for example, the heat transfer part of an embodiment, it comprises each component of following mass parts:
0.3 part of 52 parts of copper, 54 parts, aluminium, 0.7 part, magnesium, 0.8 part of iron, 0.5 part, manganese, 0.3 part of titanium, 0.1 part of chromium and vanadium.

0.05 part~0.3 part of 88 parts~93 parts, aluminium, 5.5 parts~10.5 parts of silicon, 0.3 part~0.7 part, magnesium, 0.05 part~0.3 part of copper, 0.2 part~0.8 part of iron, 0.2 part~0.5 part, manganese, 0.05 part~0.3 part of titanium, 0.05 part~0.1 part of chromium and vanadium.
It is the aluminium of 88 parts~93 parts that above-mentioned radiating part contains mass parts, can be so that the coefficient of heat conduction of radiating part remains on 200W/mK~220W/mK, when heat that LED lamp produces is after bar shaped body and heat transfer part partly dispel the heat, when remaining heat passes to radiating part by heat transfer part again, radiating part can guarantee these remaining heats evenly to be fallen apart constantly, and then prevent that heat from piling up on radiating part, cause hot-spot phenomenon.
In addition, it 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 the vanadium of 0.05 part~0.3 part that radiating part contains mass parts, can greatly improve the heat dispersion of radiating part.For example, it is the silicon of 5.5 parts~10.5 parts and the copper of 0.05 part~0.3 part that radiating part contains mass parts, can guarantee that radiating part has advantages of good mechanical properties and lighter weight, simultaneously, can also further improve the heat-conductive characteristic of radiating part, further guarantee that radiating part can evenly fall apart the after-heat via after bar shaped body and heat transfer part transmission walk constantly, and then prevent that heat from piling up on radiating part, cause hot-spot phenomenon.
For example, radiating part also comprises that mass parts is the lead (Pb) of 0.3 part~0.6 part, when containing the 0.3 part~lead of 0.6 part, radiating part can improve the tensile strength of radiating part, like this, can prevent when radiating part is cast and strikes out radiating fin, while being laminated structure, owing to being subject to excessive punching press, pullling stress and rupture.
For example, radiating part also comprises that mass parts is the niobium (Nb) of 0.02 part~0.04 part, through many experiments evidence and theory analysis, find, when the mass parts of niobium is greater than 0.02 part, can greatly improve the antioxygenic property of radiating part, be appreciated that radiating part as in assembly type bar shaped radiator with the parts of outside air contact area maximum, it is had relatively high expectations to high temperature oxidation resistance.Yet, when the mass parts of niobium is greater than 0.04 part, can cause the magnetic of radiating part sharply to increase, can the miscellaneous part in LED light fixture be exerted an influence.
For example, radiating part also comprises that mass parts is the germanium (Ge) of 0.02 part~0.03 part, through many experiments evidence and theory analysis, find, when the mass parts of germanium is greater than 0.02 part, can play beyond thought effect to the raising of the heat dispersion of radiating part, yet, when the quality accounting of germanium too much, for example, when the mass parts of germanium is greater than 2 parts, can make again the brittleness of radiating part increase.
Like this, the heat-conductive characteristic of bar shaped body, heat transfer part and radiating part successively decreases successively, formed heat-conductive characteristic gradient, and, by having compared with bigger serface radiating part dissipation of heat in external environment condition, compared to fine copper assembly type bar shaped radiator, guaranteeing that under the prerequisite of heat dispersion, weight greatly reduces; Compared to a large amount of aluminium alloy assembly type bar shaped radiators that exist on market, heat dispersion greatly strengthens.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
