Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment to the present invention is described in further detail.Hereinafter implement
Example is for illustrating the present invention, but is not limited to the scope of the present invention.
In conjunction with the sound absorption light fixture of the embodiment of the present invention shown in Fig. 1, is schematically showed, which includes lamp panel 1 and light-passing board
2, LED lamp bead 4 and control 5 be installed in lamp panel 1 roofs inner surface, be provided with the outer surface of the roof of lamp panel 1 and hang pin 6,
For lamp installation on the ceiling or is hung under ceiling, in lamp panel 1, lamp panel 1 is enclosed light-passing board 2 with light-passing board 2
Become the cavity 3 of a closing, multiple micropores (not shown) connected with cavity 3 are all placed with lamp panel 1 and light-passing board 2, micro-
Hole forms microporous sound absorbing structure with cavity 3.
The operation principle of microporous sound absorbing structure is as follows：
When sound wave reaches light fixture, will enter in cavity 3 from micropore, as cavity 3 is closed cavity (due to velocity of sound wink
When the distance propagated much larger than light fixture size, therefore can ignore the time difference that sound wave reaches each micropore of light fixture, therefore permissible
Think sound wave be while reaching each micropore), the air in cavity 3 is compressed, and then sound wave is reflected micropore again, so
Iterative cycles, now cavity 3 constantly recover by compression and then again, occur the air in micropore equivalent to the effect of spring
Of reciprocating vibration, the air in micropore is rubbed with the hole wall of micropore, so as to consume the energy of sound wave, so as to reach sound absorption
Effect.
In conjunction with shown in Fig. 2 to Fig. 4, the quantity of lamp panel 1 and light-passing board 2 can be set to one or more；When lamp panel 1
Quantity be that the quantity of one and light-passing board 2 is set to two or more, these light-passing boards 2 are sequentially overlapped and interphase distribution is in lamp panel
In 1, cavity 3 is made to be divided into several chambers by light-passing board 2；The purpose for so arranging is to make being overlapped mutually for sound absorption structure, with
The mode that successively goes forward one by one absorb sound wave can energy, such that it is able to adding unit sound absorption light fixture absorb sound wave energy, make
Obtain wave absorption more thorough.
As shown in figure 3, when the quantity that the quantity of light-passing board 2 is one and lamp panel 1 is two or more, these lamp panels 1 are successively
Superposition and interphase distribution, light-passing board 2 cover the opening of each lamp panel 1, and cavity 3 is divided into several chambers by lamp panel 1；So set
Putting can also increase unit interval interior suction and quiet down the energy of ripple so that wave absorption is more thorough.
As shown in figure 4, when the quantity of lamp panel 1 is two or more, the quantity of light-passing board 2 can be arranged to and lamp panel 1
Quantity identical, each light-passing board 2 is all accordingly in each lamp panel 1, and each light-passing board 2 is sequentially overlapped and alternate row
Cloth；So arranging can also increase unit interval interior suction and quiet down the energy of ripple so that wave absorption is more thorough.
Test proves that, the punching rate of lamp panel 1 and light-passing board 2 for 1%-2.5% scope when, microporous sound absorbing structure energy
Audible frequency scope relatively wide sound wave is enough absorbed, if after punching rate is higher than 2.5%, with the increase micropore sound absorption knot of punching rate
The audible frequency scope that structure can absorb will be more and more narrow；And if punching rate is less than 1%, with the reduction of punching rate, it will by
Sound absorption function is gradually lost；Preferably, when the punching rate of lampshade 1 and light-passing board 2 is the scope of 1.5%-2.5%, can make micro-
Hole sound absorption structure can absorb the sound wave of most wide audible frequency scope.
Equally, test proves that, the aperture of micropore for 0.2mm-0.8mm scope when, microporous sound absorbing structure can be made
The sound wave of relatively wide audible frequency scope can be absorbed, when micropore size is excessive, it will lose sound absorption function；Preferably,
When the scope that the aperture of micropore is 0.35mm-0.65mm, microporous sound absorbing structure can be enable to absorb most wide audible frequency model
The sound wave for enclosing.
The thickness of cavity 3 equally can also affect the acoustically effective of microporous sound absorbing structure, and test is proved, when the thickness of cavity 3
During for 25mm-100mm, can make microporous sound absorbing structure that preferably acoustically effective is obtained, when the thickness of cavity 3 is too high, sky can be made
" spring " in chamber 3 is softer, it is impossible to excite the air vibration in micropore well, when the thickness of cavity 3 is too low, can make cavity 3
" spring " is harder, can not excite the air vibration in micropore well, and above two situation can all weaken microporous sound absorbing structure
Sound absorption function；Preferably, the thickness of cavity is 50mm or 100mm, reaches can microporous sound absorbing structure and preferably absorb sound
Effect.
Certainly, the thickness of lamp panel 1 and light-passing board 2 equally can also affect the acoustically effective of microporous sound absorbing structure, and test is proved,
When the thickness of lamp panel 1 and light-passing board 2 is 0.5mm-2mm, microporous sound absorbing structure can be made to obtain preferably acoustically effective；If lamp
When the thickness of disk 1 and light-passing board 2 is too high, sound wave will be entered in cavity 3 with inhibition so that most of sound wave is also less than
Reach and gone back by micro-voided reflective in cavity 3, weaken the acoustically effective of microporous sound absorbing structure；And if the thickness of lamp panel 1 and light-passing board 2
When spending low, air in micropore is shorter with the stroke that micropore hole wall rubs, and equally can also weaken the suction of microporous sound absorbing structure
Sound effective value；Preferably, when the thickness of lamp panel and light-passing board is the scope of 0.6mm-1.2mm, reach can microporous sound absorbing structure
To preferably acoustically effective.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of without departing from the technology of the present invention principle, some improvement and replacement can also be made, these improve and replace
Also protection scope of the present invention should be regarded as.
