Abstract
The invention relates to the technical field of LEDs, in particular to application of flexible graphite to the field of radiating of an LED lamp. Compared with the prior art, a heat conducting fin or a radiating fin is made of flexible graphite materials, the heat conducting fin is arranged between an LED lamp circuit board and an aluminum alloy radiator and completely replaces heat conducting adhesive in the prior art, a radiator made of flexible graphite materials replaces the aluminum alloy radiator in terms of radiating, the heat conductivity of the radiator is far higher than that of copper and aluminum, an unexpected effect is achieved, the radiator made of the flexible graphite with high heat conductivity can realize more efficient radiating effect by means of special design, and cost is reduced while energy conservation and environmental protection are achieved.
Description
Technical field
The present invention relates to the LED technical field, particularly adopt the application of soft graphite that flexible graphite material processes in LED light fixture heat radiation field.
Background technology
Because the LED light fixture has advantages such as energy-conservation, power saving, brightness is high, service time is long, the LED lamp widely applied productions, live in the middle of, increase many brilliance to people.Yet; Illuminating lamp with common is the same, and the LED lamp in use also can produce great amount of heat, therefore just need on the LED lamp, heat abstractor be installed; The multiaspect radiator that the heat abstractor of LED light fixture of the prior art generally all adopts aluminum alloy materials to process; When here radiator contacts with the LED light fixture, generally also need be coated with some heat-conducting glues and plug the gap, pass to the heat on the LED light fixture on the radiator through heat-conducting glue; Spread out of heat from radiator again, but because the heat transfer property of heat-conducting glue is poor.Therefore can not in time shed the heat on the LED light fixture to biography, cause radiating effect poor.
Summary of the invention
For solving existing defective of LED lamp and problem in the prior art, the application of soft graphite in LED light fixture heat radiation field is provided.
The technical scheme that the present invention is adopted for its technical problem of solution is: conducting strip of the present invention or fin adopt flexible graphite material to process; The soft graphite conducting strip is the flexible sheet shape; And be arranged between heater and the radiator; Described soft graphite fin compacting is arbitrary shape, and replaces metal heat sinks such as copper, aluminium.
The invention has the beneficial effects as follows: compared with prior art; Conducting strip of the present invention or fin adopt flexible graphite material to process; Conducting strip is arranged between LED lamp driver plate and the aluminium alloy heat radiator, has substituted heat-conducting glue of the prior art fully, and the fin aspect replaces aluminium alloy heat radiator; The far ultra copper of thermal conductivity, aluminium; Play a beyond thought effect, adopt the radiator of high thermal conductivity flexible graphite can realize dispelling the heat more efficiently, also energy-saving and environmental protection when reducing cost through particular design.
The specific embodiment
Soft graphite of the present invention is in the application in LED light fixture heat radiation field; Soft graphite is called expanded graphite again; Belong to non-cellulosic material, soft graphite is to be raw material with the natural flake graphite, carries out the intercalation chemistry reaction through acidification; Expanding through washing, drying and high temperature obtains high power expanded graphite worm again, just can make conducting strip or fin through calendering, pressing process more on this basis.The conducting strip operated by rotary motion that this employing flexible graphite material is processed is between LED lamp driver plate and aluminium alloy heat radiator; Substituted heat-conducting glue of the prior art fully, fin can replace aluminium alloy heat radiator fully, and its heat conductivility is very desirable; Metal alloys such as the far ultra copper of thermal conductivity, aluminium; Play a beyond thought effect, adopt the radiator of soft graphite can realize dispelling the heat more efficiently simultaneously, also energy-saving and environmental protection when reducing cost through particular design.
Main protection main points of the present invention are soft graphite application as the heat conduction and heat radiation material on the LED light fixture; Widely applied soft graphite in the prior art; Soft graphite all is to be used for field of sealing technology in the prior art; It has good anticorrosive property; Good compression resilience and high strength property, how much pads of various round complicacies are widely used in pipeline, valve, pump, pressure vessel, heat exchanger, condenser, generator, air compressor, blast pipe, refrigeration machine etc. and use as seal.The present invention utilizes the characteristic of high temperature resistant, the high heat conduction of soft graphite; Be used to process the application of soft graphite in LED light fixture heat radiation field; Have than the better heat-conducting effect of metal alloys such as copper, aluminium, this effect is beyond thought, substitutes heat-conducting glue of the prior art and radiator fully; When reducing cost, also have advantages such as energy-saving and environmental protection, have good market prospects.
According to embodiments of the invention describing the present invention property and nonrestrictive description, but should be understood that and do not breaking away under the situation of the relevant protection domain that limits claim that those skilled in the art can make change and/or revise.
