Description
Technical field
The invention belongs to light emitting device technologies fields, and in particular to a kind of LEDbulb lamp.
Background technique
LED is as a kind of new type light source, since with energy-saving and environmental protection, the service life is long, starting speed is fast, can control luminous light
It composes and the size with width is forbidden to make the unrivaled advantage of the more high conventional light source of chroma and developed on an unprecedented scale.It is high-power
LED solid-state lighting has been the most important illumination revolution since incandescent lamp invention.Semiconductor LED material can directly convert electric energy
For luminous energy, have with the maximum difference of conventional illumination sources, luminous efficiency is high, and energy consumption is only ordinary incandescent lamp 1/8th;Longevity
Life length;No stroboscopic, without infrared and ultraviolet radioactive and without mercury element etc., be typical energy conservation, environmentally protective illumination.
Along with the increase of LED current intensity and luminous quantity, the calorific value of LED chip is also risen with it, defeated for LED
Enter the energy 70% is all consumed in the form of heat.If the external world cannot be discharged in these heats in time, the temperature rise of chip is caused to imitate
It answers, the service life of LED and light output can all have a greatly reduced quality;With technological progress and the continuous expansion of market scale, the function of single LED
Rate density and luminous efficiency are being continuously improved, and to LED encapsulation material and technique, higher requirements are also raised.
LED light shell is not only to cover on lamp for the effect for making light flock together, and can also prevent from getting an electric shock, to protection
Eyes also have effect, so can have lamp housing on each lamp.Now many industrial lighting LED lamps be applied to military affairs, space flight and aviation,
The fields such as metallurgy, mining, the mostly of use are the corrosion-resistant high-strength materials such as aluminium alloy.Aluminum shell is easy heat dissipation, exquisite appearance, weight
Amount is light and handy, and many high-end electronic products all use aluminium shell.Such as the apple laptop of Apple Inc. " MacPro " is high
It holds computer series of products to use full aluminium shell, is easy to laptop radiating, such computer even connects fan without dress;
LED can increase the service life of wick using aluminum shell, and LED light is made to seem beautiful.But the thermal expansion coefficient of common aluminum alloy with
LED chip is widely different, when temperature change is very big or packaging operation does not generate heat skew, initiation chip flaw and hair easily at that time
Light efficiency reduces.Since LED luminance increases with the increase of driving current, to the LED of more high brightness, common aluminum alloy shell is
It is unable to satisfy its cooling requirements;Therefore it needs to develop new LED light shell, improves the radiating rate of lamp.
Summary of the invention
The present invention for existing LEDbulb lamp lamp housing there are the shortcomings that, provide it is a kind of it is high heat dissipation, strong mechanical performance aluminium close
Gold production LED light shell, meets the radiating requirements of LED light.
Above-mentioned purpose of the invention can be realized by the following technical scheme: a kind of LEDbulb lamp, the LEDbulb lamp
Shell be made of aluminum alloy materials, the ingredient and its weight percent of the aluminum alloy materials are as follows: Be:1.0-3.0%, Cu:
0.5-1.8%, porous graphite: 0.08-0.58%, nanometer silicon carbide: 0.2-1.0%, surplus Al.
Preferably, the ingredient and its weight percent of the aluminum alloy materials are as follows: Be:1.5-2.3%, Cu:1.0-
1.2%, porous graphite: 0.18-0.32%, nanometer silicon carbide: 0.3-0.5%, surplus Al.
Beryllium element and copper have high heat conductance, and after a small amount of beryllium and copper are added in Al, the thermal conductivity of aluminium alloy is big
Amplitude improves, and the radiating rate as LED light shell also greatly improves.Although the thermal conductivity of beryllium and copper is high, its content is needed
It wants strict control, excessive beryllium and copper to improve the radiating rate of aluminium alloy unhelpful, can also reduce the mechanical property of aluminium alloy.It is more
Hole graphite dispersion is in aluminum alloy materials, and graphite is because the unique crystal grain orientation of its carbon atom is so that material both direction along plane
With very strong thermal conductivity, the heat transfer of material can be realized by the lattice vibration of carbon atom, to improve dissipating for aluminium alloy
It is hot, while porous graphite, the hole of formation, the electronics be conducive in metal move freely, the electronics of high-temperature region carries heat
Amount is moved to low-temperature space, realizes the transfer of heat.Nanometer silicon carbide is highly dispersed in aluminium alloy, improves the mechanical property of material
And thermal diffusivity.
Preferably, the aperture of the porous graphite is 0.5-10nm, specific surface area 500-1000m2/g.Porous graphite
Aperture need it is small and fine and close.
Preferably, the partial size of the nanometer silicon carbide is 50-200nm.
Preferably, the preparation method of the aluminum alloy materials is the following steps are included: weigh raw material mixing by composition proportion
Uniformly, the heating and melting at 700-800 DEG C, slab of casting to obtain, in high-temperature vacuum furnace, slab is heated with the speed of >=20 DEG C/s
To 900-1100 DEG C, it then is heated to 1500-1800 DEG C with the speed of 0.1-0.5 DEG C/s, 45-90min is kept the temperature, is returned after cooling
Fire.
Be, Cu, porous graphite, nanometer silicon carbide and Al heating melting of the present invention, cast after slab, carry out at solid solution
Reason is first heated to 900-1100 DEG C with the speed of >=20 DEG C/s, at this time dissolving metal, then will be warm by the way of slowly heating up
Degree is increased to 1500-1800 DEG C, is formed in raw metal and metal structure because the fusing point of nanometer silicon carbide will be significantly larger than
Hardening constituent, when hardening constituent is dissolved, nanometer silicon carbide still exists in granular form, alloy can be induced respectively to organize raw along particle
It is long, because of nanometer silicon carbide high degree of dispersion in the alloy, so that each mutually homoepitaxial in the alloy, and growing up for crystal grain is hindered, carefully
Change crystal grain.
Preferably, the tempering are as follows: be heated to 250-400 DEG C of heat preservation tempering 2-5h.
Preferably, when being heated to 250-400 DEG C, with the ultrasonication 30-60min of 500-1000w.When tempering, into
On the one hand row ultrasonication, ultrasonication can refine crystal grain, improve toughness of material, and on the other hand, ultrasound is because of its uniqueness
Effect, after being processed, the metal electron degree of being bound of aluminum alloy organization is reduced, and forms more free electrons, heat dissipation performance
It is largely increased.
Compared with prior art, the present invention for LEDbulb lamp shell aluminium alloy contain Be, Cu, porous graphite and
Nanometer silicon carbide ingredient interacts between each ingredient, improves heat dissipation performance, and pass through slow heating solution treatment, nano-sized carbon
SiClx induction hardening constituent is evenly distributed, and further increases the mechanical property and thermal diffusivity of aluminum alloy materials.
