Embodiment
Referring to picture, the present invention is described in further detail in conjunction with the embodiments, to make those skilled in the art join
Book word can be implemented according to this as directed.
As shown in figure 1, a kind of LED lamp of use porous metal material radiator is listed in this case, its entirety includes：Light source
Component, shell, radiator, driving power supply, radiator fan.
Light source assembly includes LED lamp substrate 3 and led lamp beads 2.Led lamp substrates 3 have two sides, the of LED lamp substrate 3
Some led lamp beads 2 are welded with one surface, the second surface of LED lamp substrate 3 is in contact with radiator 5；LED lamp substrate 3 is by aluminum
Into the good heat-transfer of aluminium, the heat of led lamp beads 2 reaches radiator 5 through LED lamp substrate 3.
Radiator 5 is made up of porous metal material, use for porous aluminum, be dispersed with porous aluminum it is some have direction or with
The hole of machine, these holes are equivalent to heat emission hole, while these holes make it that the specific surface area of porous metal material is big, heat exchange
Perfect heat-dissipating.But the heat-conductive characteristic of porous aluminum but be not so good as aluminium, so the contact with LED lamp substrate 3 of radiator 5 need through
Surface-treated layer 4 is crossed, the material of superficial layer 4 can be heat conductive silica gel, and LED lamp substrate 3 is in close contact with superficial layer 4, by heat
Pass to radiator 5.The structure of radiator 5 is as shown in Fig. 2 radiator 5 includes spaced top plate and bottom plate and setting
Some fin 9 between the top plate and bottom plate, the second surface of top plate and led substrates 3 is brought into close contact, and fin 9 is
The arc platy structure of outside water conservancy diversion, the upper and lower ends of fin 9 are fitted setting with top plate and bottom plate respectively, in the middle of radiator 9
A cavity 13 is reserved with, some fin 9 are equally spaced in the periphery of cavity 13；Formed between each two fin 9
It is interconnected on the inside of the air channel of outside air outlet angle, air channel by cavity 13
Driving power supply 11, because led work is at a dc voltage, it is necessary to which power supply driver provides safe voltage and electricity
Stream.Driving power supply 11 is placed in the cavity 13 of radiator 5.
Radiator fan, including centrifugal fan 10 and aerofoil fan 6, aerofoil fan 6 are placed on the outside of the substrate of radiator 5,
The blade of aerofoil fan 6 can promote air to be flowed with axle identical direction, when aerofoil fan 6 is opened, above light fixture
In air push-in radiator 5.Centrifugal fan 10 is placed in the cavity 13 of radiator 9, and air is by after centrifugal fan 10 axially suction
Through being sent to perpendicular to the direction of axis in fin 9, when centrifugal fan 10 is opened, the air of fan upper and lower is through centrifuging wind
Thrown out in the presence of fan leaf from circumferencial direction, for ease of the circulation of gas, according to the flow direction of gas, by radiator
5 fin 9 is designed as arc, the air channel outflow that the gas thrown away through centrifugal fan can be formed between fin 5.Wherein,
Adjacent two pieces of fin 9 formation air intake vent connected with cavity 13 and the air outlet connected with outer space, air outlet are more than
Air intake vent, centrifugal fan 10 is towards air intake vent air-out, and the air-out direction of centrifugal fan 10 points to the inner arc side wall of fin 9.Dissipate
Hot-air fan accelerates the air flow of LED lamp so that heat is quickly taken out of outside light fixture through air.
Shell includes diffuser 1, panel 7, fan drum 8.Diffuser 1 is placed on LED lamp substrate 3, for spreading light beam.
Panel 7 is placed in the air inlet of aerofoil fan 6, and the structure of panel is as shown in figure 3, the entering provided with some dust-proof radiatings of panel 7
Gas port 12, air inlet 12 is with outside radial distribution on panel 7.Aerofoil fan 6 is externally provided with a fan drum 8 and the phase of panel 7
Even, the material of fan drum 8 is porous metal material, and porous metal material has good acoustical absorptivity, can reduce fan
Noise.
In above-mentioned technical proposal, driving power supply 11 is connected with aerofoil fan 6 and centrifugal fan 10, the work of driving power supply 11
Make, led is lighted, and aerofoil fan 6 and centrifugal fan 10 are opened simultaneously, and led lamp beads 2 are generated heat, and heat is delivered to through LED lamp substrate 3
Radiator 5, while the driving power supply 11 being placed between the centrifugal fan 10 of aerofoil fan 6 can also generate heat, radiator 5 itself start to
Distribute heat outside.When radiator fan works, as denoted by the arrows in fig. 2, the air above light fixture is passed through the air direct of LED lamp
The air inlet 12 on panel 7 is crossed by the continuous inside for entering radiator 5 after aerofoil fan 6, when air passes through driving power supply 11
Its heat is taken away, the gas with heat is by air channel discharge led of the effect of centrifugal fan 10 through being formed between fin 9
Outside lamp, because the shell of radiator 5 and aerofoil fan 6 is made by porous metal material, porous metal material has fine again
Sound absorption qualities, the noise of fan can absorb by porous metal material, the perfect heat-dissipating of LED lamp and noise is small.
From the above mentioned, LED lamp of the invention is by the way that porous metal material is applied on the radiator of LED lamp, using many
The fabulous heat dispersion of mesoporous metal material is distributed heat to outside lamp, while setting two fans in lamp, is matched somebody with somebody in two fans
Under conjunction, the gas flowing in lamp is accelerated, heat is quickly taken out of outside lamp, and whole LED lamp has splendid heat dispersion, can
Ensure LED lamp working stability and improve led service lifes to greatest extent.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details.
