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 fin contains mass parts, can make the coefficient of heat conduction of radiating fin remain on 200W/mK～220W/mK, when heat that LED lamp produces is after the heat radiation of heat conduction circle and heat transfer part part, when remaining heat passes to radiating fin by heat transfer part again, radiating fin can guarantee these remaining heats evenly to be fallen apart constantly, and then prevent that heat from piling up on radiating fin, 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 fin contains mass parts, can greatly improve the heat dispersion of radiating fin.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 fin contains mass parts, can guarantee that radiating fin has advantages of good mechanical properties and lighter weight, simultaneously, can also further improve the heat-conductive characteristic of radiating fin, further guarantee that radiating fin can will evenly fall apart via the after-heat after heat conduction circle and heat transfer part transmission constantly, and then prevent that heat from piling up on radiating fin, cause hot-spot phenomenon.
For example, radiating fin 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 fin can improve the tensile strength of radiating fin, like this, can prevent when radiating fin 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, radiating fin 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 radiating fin, be appreciated that radiating fin as in radiating piece 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, can cause the magnetic of radiating fin sharply to increase, can exert an influence to the miscellaneous part in LED light fixture.
For example, radiating fin 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, beyond thought effect is played in the raising of heat dispersion that can be to radiating fin, but, 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 fin increase.
Like this, the heat-conductive characteristic of heat conduction circle, heat transfer part and the radiating fin of radiating piece successively decreases successively, form heat-conductive characteristic gradient, and, by having compared with bigger serface radiating fin dissipation of heat in external environment condition, compared to fine copper radiating piece, under the prerequisite of guaranteeing heat dispersion, weight greatly reduces; Compared to a large amount of aluminium alloy radiating pieces that exist on market, heat dispersion greatly strengthens.
Above-mentioned LED track lamp 10 is by radiating piece 500 is set, thus the heat that the LED lamp 450 that can fall apart in time fast produces, and radiating effect is better.In addition, bonnet 440 is rotationally connected with support 320, simultaneously, support 320 also can rotate relative to guide rail head 310, thereby make bonnet 440 can carry out the rotation of two frees degree by guide rail head 310 and support 320 simultaneously, thereby further drive the light beam that LED lamp 450 penetrates can carry out the rotation of two frees degree simultaneously, thereby made range of exposures wider.
An example is, a kind of LED guide rail of the present invention lighting comprises the described LED track lamp of above-mentioned arbitrary embodiment.
An example is that LED guide rail lighting comprises several LED track lamps 10, each LED track lamp 10 series connection settings.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
