Abstract
The invention discloses a material of a heat radiation body of an LED (light-emitting diode) lamp. The material is prepared from the following components in percentage by weight: 45%-65% of polyphenylene sulfide, 20%-40% of aluminum powder and 10%-15% of graphite powder. The material disclosed by the invention integrates the advantages of the polyphenylene sulfide, the aluminum powder and the graphite powder, and further has the beneficial effects of higher heat radiation speed and great heat conduction performance. The LED lamp prepared by using the material disclosed by the invention has a good heat radiation effect and is more economic and durable.
Description
Technical field
The present invention relates to the technical field of LED lamp, refer in particular to a kind of heat sinking body material of LED lamp.
Background technology
In the existing life, the LED light fixture has energy-conservation, and the life-span is long, suitability is good, and is lucuriant in design, the characteristics that luminous color is pure, and has an environmental protection, without poisonous metal, the advantage that waste reclaims easily, these have remedied the deficiency of ordinary light source, development along with the LED technology, the LED light fixture is also more and more, and the kind style is numerous and diverse, is widely used in all trades and professions.
Existing LED lamp, have part as Chinese patent CN201020196636 " LED lighting bulb " middle announcement, comprise lamp holder 60, isolator 20, circuit card 50, radiator 10, LED lamp panel (light source) 30 and lampshade 40, although radiator 10 adopts metal (aluminum) to make, has better heat dissipation effect, but still have the undesirable defective of heat radiation, greatly affect the use of LED lamp.
Therefore, the inventor makes further research this, develops a kind of heat sinking body material of LED lamp, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of radiator material of LED lamp, have good heat dispersion, make the LED lamp durable more economically.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of radiator material of LED lamp, it is to be made by mass percentage by following component: polyphenylene sulfide 45%～65%, aluminium powder 20%～40% and Graphite Powder 99 10%～15%.
Preferably, Graphite Powder 99 is the graphite worm powder.
Preferably, it is to be made by mass percentage by following component: polyphenylene sulfide 45%, aluminium powder 40%, Graphite Powder 99 15%.
Preferably, it is to be made by mass percentage by following component: polyphenylene sulfide 50%, aluminium powder 35%, Graphite Powder 99 15%.
Preferably, it is to be made by mass percentage by following component: polyphenylene sulfide 65%, aluminium powder 25%, Graphite Powder 99 10%.
Polyphenylene sulfide is a kind of novel high-performance thermoplastic resin, has the advantages such as physical strength height, high temperature resistant, chemical proofing, difficult combustion, Heat stability is good, electrical property be good.
And aluminium powder lightweight with it, have good electroconductibility and a heat conductivility, resistance to oxidation and in all trades and professions, being widely used again.
Graphite Powder 99 has good high thermal resistance, and its thermal conductivity is good, surpasses the metallic substance such as steel, iron, lead, also has good oilness.
After adopting such scheme, the present invention has gathered polyphenylene sulfide, aluminium powder and Graphite Powder 99 three's advantage, so that radiating rate of the present invention is faster, has good heat conductivility.The LED lamp excellent in heat dissipation effect of using the present invention to make, more durable.

Label declaration
Embodiment
The present invention is further illustrated below in conjunction with specific embodiment.
The radiator material of a kind of LED lamp that the present invention discloses, it is to be made by mass percentage by following component: polyphenylene sulfide 45%～65%, aluminium powder 20%～40%, Graphite Powder 99 10%～15%.Graphite Powder 99 specifically can be used the graphite worm powder.
As shown in the table, listed 8 embodiment of the present invention, and the performance test results that is made the LED lamp by these 8 embodiment.
In the present embodiment, select the density of material of polyphenylene sulfide to be about 1.4g/cm
3, the density of material of aluminium powder is about 2.7～2.8g/cm
3, the density of material of Graphite Powder 99 is about 2.3g/cm
3
Can see by above tabulation, adopt above-mentioned prescription after, it is good that the present invention has a good temperature tolerance, flame retardant resistance, intensity, the characteristics that thermal conductivity is high.The LED lamp excellent in heat dissipation effect of using the present invention to make, more durable.
Above-mentioned only is specific embodiments of the invention, but design concept of the present invention is not limited to this, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should belong to the behavior of invading protection domain of the present invention.
