Above-mentioned heat conduction main body contains copper (Cu) can make the heat conductivility of heat conduction main body remain on a higher level.In the time that the mass parts of copper is 93 parts～97 parts, more than the coefficient of heat conduction of heat conduction main body 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 conduction main body entirety, to prevent that heat from accumulating on the contact position between LED lamp and heat conduction main body, causes the generation of hot-spot phenomenon.And the density of heat conduction main body but only has 8.0kg/m3～8.1kg/m3, be far smaller than the density of fine copper, can effectively alleviate like this weight of heat conduction main body, be more conducive to install and manufacture, 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 unit, the larger explanation heat conductivility of this numerical value is better.

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 body 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 body 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.
For example, the heat radiation main body of an embodiment, it comprises each component of following mass parts:
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 heat radiation main body contains mass parts, the coefficient of heat conduction of main body of can making to dispel the heat remains on 200W/mK～220W/mK, when heat that LED lamp produces is after the heat radiation of heat conduction main body and heat transfer body part, when remaining heat passes to heat radiation main body by heat transfer body again, heat radiation main body can guarantee these remaining heats evenly to be fallen apart constantly, and then prevent that heat from piling up in main body in heat radiation, 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 heat radiation main body contains mass parts, can greatly improve the heat dispersion of heat radiation main body.For example, it is the silicon of 5.5 parts～10.5 parts and the copper of 0.05 part～0.3 part that heat radiation main body contains mass parts, the main body of can guaranteeing to dispel the heat has advantages of good mechanical properties and lighter weight, simultaneously, can also further improve the heat-conductive characteristic of heat radiation main body, the main body of further guaranteeing to dispel the heat can will evenly fall apart via the after-heat after heat conduction main body and heat transfer body transmission constantly, and then prevents that heat from piling up in main body in heat radiation, causes hot-spot phenomenon.
For example, heat radiation main body also comprises that mass parts is the lead (Pb) of 0.3 part～0.6 part, when the heat radiation main body lead that contains 0.3 part～0.6 part can improve the tensile strength of heat radiation main body, like this, can prevent when heat radiation main body is cast and strikes out radiating fin, while being laminated structure, pullling stress and rupture owing to being subject to excessive punching press.
For example, heat radiation main body also comprises that mass parts is the niobium (Nb) of 0.02 part～0.04 part, find through many experiments evidence and theory analysis, in the time that the mass parts of niobium is greater than 0.02 part, can greatly improve the antioxygenic property of heat radiation main body, be appreciated that heat radiation main body as in installing radiator with the parts of outside air contact area maximum, it is had relatively high expectations to high temperature oxidation resistance.But in the time that the mass parts of niobium is greater than 0.04 part, the magnetic of the main body that can cause dispelling the heat sharply increases, and can exert an influence to the miscellaneous part in LED light fixture.
For example, heat radiation main body also comprises that mass parts is the germanium (Ge) of 0.02 part～0.03 part, find through many experiments evidence and theory analysis, in the time that the mass parts of germanium is greater than 0.02 part, can play beyond thought effect to the raising of heat dispersion of heat radiation main body, but, when the quality accounting of germanium too much, for example, when the mass parts of germanium is greater than 2 parts, the brittleness of the main body that can make again to dispel the heat increases.
Like this, the heat-conductive characteristic of heat conduction main body, heat transfer body and the heat radiation main body of radiating subassembly successively decreases successively, form heat-conductive characteristic gradient, and, by having compared with bigger serface heat radiation main body dissipation of heat in external environment condition, compared to fine copper installing radiator, under the prerequisite of guaranteeing heat dispersion, weight greatly reduces; Compared to a large amount of aluminium alloy installing radiators that exist on market, heat dispersion greatly strengthens.
It should be noted that, other embodiment of the present invention also comprise, the technical characterictic in the various embodiments described above mutually combine form, the LED illuminating lamp of the front end heat dissipation type that can implement, like this, can realize good heat dissipation effect and there is the technique effect of front end heat sinking function.
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.
