Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, this utility model is further described.
As it is shown in figure 1, this utility model includes that sound absorbing module and lighting module, described sound absorbing module include flat board
1 and be fixed on the back of the body chamber 2 at flat board 1 back side, described flat board 1 is microperforated panel, and described lighting module includes LED
Surface-mounted lamp band 3, described Surface-mount LED lamp band 3 is pasted onto in back of the body chamber 2.
Sound-absorbing material is had 2 requirements: using environment is the acoustical design that room acoustics is decorated, required sound absorber
Answer moistureproof and waterproof, certain surface pressing can be born simultaneously；Require that the acoustic absorptivity bandwidth more than 0.5 reaches
More than 2000Hz, main sound absorption frequency is 400Hz～about 2000Hz.According to above 2 requirements,
The microperforated panel that the transparent acrylic selecting flat board 1 to be 0.4mm is made, the sheet material in back of the body chamber 2 is 1mm
Thick aluminium alloy plate.The mode selecting laser beam perforation carries out perforation processing to the acrylic board that 0.4mm is thick, and perforation is straight
Footpath is within 1mm, and punching rate is 2%, and the size of flat board 1 is 97mm × 600mm.
As in figure 2 it is shown, described back of the body chamber 2 includes two groups of son back of the body chambeies 21.The back of the body chamber 2 beam overall within a cycle
Degree should be not more than the wavelength of 1/4 times of intermediate frequency (about 500Hz), overall width be sub-back of the body chamber 21 width and
Spacer width sum between each height back of the body chamber 21.In the present embodiment, the width in sub-back of the body chamber 21 is 15mm,
Dividing plate between son back of the body chamber 21 is 1mm aluminium alloy plate, so back of the body chamber 2 beam overall 97mm, meets what beam overall limited
Requirement.The width in each height back of the body chamber 21 can be equal, it is also possible to unequal.Described back of the body chamber 2 includes that two groups are put down
The son back of the body chamber 21 of row arrangement, often group back of the body chamber include 3 that depth ratio from outside to inside is 1:4:2 adjacent
Son back of the body chamber 21.Son back of the body chamber 211,212,213 is one group, and sub-back of the body chamber 214,215,216 is another group.
The table 1 monolayer micropunch backboard chamber degree of depth and resonant frequency (sound absorption peak position) regularity of distribution
The degree of depth in back of the body chamber 2 is relevant with resonant frequency, and table 1 is thickness of slab t=0.4mm, penetration hole diameter d=0.4mm,
During punching rate 1.8%, the partial depth of monolayer porous plate acoustic adsorption device and sound absorption peak distribution relation table, be available for preliminary
The reference of design.The back of the body chamber degree of depth provided according to table 1 and the reference of resonant frequency relation, consider space limit
Value and sound sucting band requirement, select unit depth H in first group of son back of the body chamber1=25mm, the list in second group of son back of the body chamber
Bit depth H2=5mm, therefore resulting bottle back of the body chamber 211-216 actual grade is respectively 25mm, 100mm, 50mm, 10mm,
20mm, 5mm.
Illuminating effect is had 2 requirements: design use high-grade office building open office, public build
Build, the region such as green building, it is desirable to light fixture length in service life, stable, energy-conservation；Design uses in airport high ferro
The region such as hall, subway, it is desirable to light fixture shock resistance is got well and requires that lamp assembled parts easily dismount recoverable.
Comprehensive above 2 points, and consider that nowadays Intellectualized Tendency, Surface-mount LED lamp band 3 select 5050 types to be pasted onto aluminum
Alloy cavity inner wall, and installation infrared inductive switch 5, annexation is as shown in Figure 3.Described infrared induction is opened
Close 5 selections and open up Anda 86 type (TAD-T28AD-12) human body infrared induction switch, can be according to actual need
Ask and select be fixed on the end in back of the body chamber 2 or extended to the zone of action of people by wiring.
Described Surface-mount LED lamp band 3 is a plurality of, is attached to respectively in different son back of the body chamber 21.Surface-mount LED lamp band 3
Between connect with supporting connector, connected mode is series connection, and the light bar of outermost Aconitum carmichaeli Debx. back of the body intracavity is connect by adapter
220V dispatch from foreign news agency.Using Surface-mount LED lamp band energy consumption is the 1/10 of general electric filament lamp, is the 1/4 of common energy-saving lamp,
Life-span is permanent, can use about 100,000 hours；Light fixture coordinates infrared sensing switch can realize turning on light during people, nothing
The energy-saving effect turned off the light during people, for places such as aisle, hotel, cinema's display lamps；Surface-mount LED lamp band simultaneously
Compare electric filament lamp and electricity-saving lamp has more preferable stability and shock resistance, be particularly suited for the places such as subway station.
Back of the body chamber 2 is integrally fixed on flat board 1 back side, and the surrounding in back of the body chamber 2 is aluminium alloy plate, relative with flat board 1
The opening that one side is back of the body chamber 2, its opening microperforated panel covers, and bonding firmly with professional glue,
Form the sound absorption and lighting integrated gasifying device closed.
The sound absorbing capabilities (normal incident absorption coefficient) of sound absorption and lighting integrated gasifying device is estimated.Fig. 4
It is the sound absorber gridding methods of finite element simulation, including microperforated panel 1, sub-back of the body chamber 211-216, virtual
Plane wave incidence impedance tube 4, plane wave incidence direction is D direction.The normal incident absorption coefficient result of sound absorber
Predicting the outcome as it is shown in figure 5, curve A is analytical calculation model, curve B is Finite Element Numerical Simulation result,
Curve C is experimental measurements.It is limited to the size of sample and impedance tube, the effective frequency of experimental measurements
Scope is stopped to 1700Hz, and three can be well on validation-cross.Compare tradition porous plate acoustic adsorption device, this reality
Carrying on the back chamber with each height of sound absorber of novel middle design uses mode in parallel to arrange, through finite element simulation and experiment
Checking, it is contemplated that effect is that acoustic absorptivity is more than the frequency range of 0.5 and can cover 440Hz to 4000Hz,
Noise reduction coefficient can reach more than 0.7, will significantly reduce noise sound and improve room reverberation time, practicality
By force, clean environment firendly, non-secondary pollution, it is ensured that high performance simultaneously saving uses space.This result shows,
The Wide band high performance porous plate acoustic adsorption device with not even depth back of the body cavity configuration described in the utility model, it is inhaled
Acoustic performance meets most room acoustics finishings and noise control occasion, such as open office ceiling and side wall
The demand of sound absorption finishing.Additionally, sound absorbing module and lighting module integrated design, and meet certain modulus,
Not only reduce the operation of construction, decrease installing space；Can promote to improve at present some need sound absorption simultaneously
Process but because of some condition limits cannot the indoor noise environment in place of separately installed sound-absorbing material.
