Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to a sound-absorbing chandelier. Background Technology

[0002] Lighting fixtures are an indispensable element in modern architectural design, not only fulfilling the basic functional requirement of providing illumination but also significantly shaping the overall atmosphere and visual effect of a space. As people's demands for quality of life continue to rise, traditional single-function lighting fixtures are gradually failing to meet the needs of diverse usage scenarios. In recent years, the industry has gradually explored innovative design concepts that integrate multiple functions, striving to optimize space utilization efficiency while enhancing user experience.

[0003] Traditional solutions to indoor noise problems mainly include adding dedicated sound insulation panels or laying sound-absorbing cotton. Some designs also attempt to reduce noise by altering the shape of the lampshade, such as using a honeycomb structure to disperse sound waves. However, these methods have not been very effective in controlling noise. Therefore, there is a need for an integrated lighting fixture that can provide illumination while efficiently absorbing noise. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a sound-absorbing chandelier.

[0005] The sound-absorbing pendant light provided in this application adopts the following technical solution:

[0006] A sound-absorbing chandelier includes:

[0007] case;

[0008] A sound-absorbing structural layer is disposed on the inner wall of the housing to form a sound-insulating cavity inside the housing; and

[0009] A light-emitting module is installed at the end of the housing and can project light out of the housing.

[0010] By adopting the above technical solutions, the sound-absorbing chandelier combines sound-absorbing structure with lighting function, effectively reducing environmental noise while providing illumination. The sound-absorbing structural layer on the inner wall of the housing absorbs sound wave energy and reduces sound reflection, thereby improving the acoustic effect in the space. The light-emitting module is installed at the end of the housing to ensure that light can be evenly projected onto the external environment to meet lighting needs.

[0011] Optionally, the housing includes an outer shell frame, an upper structural plate, and a lower structural plate. The lower structural plate is located at the bottom of the outer shell frame, and the upper structural plate is disposed at the top of the outer shell frame. The outer shell frame, the upper structural plate, and the lower structural plate are combined to form a receiving space. The light-emitting module is fixed to the lower structural plate and located in the receiving space.

[0012] By adopting the above technical solution, the housing is composed of an outer frame, an upper structural panel, and a lower structural panel to form an accommodating space. This structural design effectively improves the overall stability of the chandelier while providing a reasonable installation position for the sound-absorbing structural layer and the light-emitting module. The light-emitting module is fixed on the lower structural panel and located within the accommodating space, ensuring the realization of the lighting function while avoiding direct impact from the external environment on the light-emitting module, thereby improving the service life and safety of the chandelier.

[0013] Optionally, the outer shell frame includes two shells arranged opposite each other, and a connecting plate is provided on the shell. The lower structural plate and the upper structural plate are respectively fixed to the shell through the connecting plate.

[0014] By adopting the above technical solution, the outer shell frame of the housing consists of two shells arranged opposite each other, and the lower and upper structural plates are fixed to the outer shells by connecting plates. This design enhances the overall structural stability of the housing, ensuring that the sound-absorbing pendant light will not deform or loosen due to external vibration or gravity during installation and use. At the same time, the modular assembly method facilitates the production and maintenance of the housing, reducing manufacturing costs and assembly difficulty.

[0015] Optionally, a connecting strip is provided between the front and rear opposite shells, and the connecting strip has a groove located inside the shell along its length.

[0016] By adopting the above technical solution, the connecting strip enhances the structural stability between the front and rear opposing shells, preventing deformation or separation under external forces. The groove design further optimizes the internal space layout of the shell, facilitating the installation and fixing of other components, while also helping to reduce the overall weight and improve the installation safety of the chandelier.

[0017] Optionally, the sound-absorbing structure layer includes a first sound-absorbing layer and a second sound-absorbing layer. The first sound-absorbing layer is attached to the inner wall of the outer shell, and the opposite sides of the second sound-absorbing layer are snapped onto the connecting strip and are tightly attached to the first sound-absorbing layer. A sound-insulating cavity is formed between the first sound-absorbing layer and the second sound-absorbing layer.

[0018] By adopting the above technical solution, this structure can effectively enhance the sound absorption effect, while the layered design improves the stability and ease of assembly of the sound absorption structure.

[0019] Optionally, the side of the second sound-absorbing layer facing away from the first sound-absorbing layer is provided with a sound wave interference structure. The sound wave interference structure is an array of hemispherical protrusions, and the hemispherical protrusions are cavities with circular through holes on their surfaces.

[0020] By adopting the above technical solution, this design can effectively enhance the sound absorption effect. The hemispherical protruding cavity structure can capture and weaken sound wave energy, while the circular through holes further promote the reflection and interference of sound waves within the cavity, thereby reducing sound wave transmission and improving the overall sound insulation performance. At the same time, the array arrangement ensures that the sound wave interference structure has a wider and more uniform range of effect on sound waves, significantly improving the noise reduction capability of the sound-absorbing pendant light in actual use.

[0021] Optionally, the outer shell, the first sound-absorbing layer, and the second sound-absorbing layer are all curved plates.

[0022] By adopting the above technical solution, the outer shell, first sound-absorbing layer, and second sound-absorbing layer of the sound-absorbing chandelier all feature an arc-shaped plate design. This effectively increases the contact area between the sound-absorbing structure and sound waves, enhancing the sound absorption effect. Simultaneously, the arc-shaped plate design helps optimize the propagation path of sound waves within the shell, reducing sound wave reflection and resonance, further improving the overall sound insulation performance. Furthermore, the arc-shaped plate structure also possesses good aesthetics and stability, allowing the chandelier to meet functional requirements while also having a decorative effect.

[0023] Optionally, the light-emitting module includes a lamp body, a power cord, and a heat dissipation component. The lamp body is connected to the lower structural plate through the heat dissipation component, the power cord is connected to the lamp body, and the heat dissipation component is detachably connected to the lamp body.

[0024] By adopting the above technical solution, the light-emitting module of the sound-absorbing chandelier is connected to the lower structural plate through a heat dissipation component, which effectively improves the heat dissipation performance of the lamp body and extends its service life. Meanwhile, the power cord connection ensures normal power supply to the lamp body, and the detachable connection design between the heat dissipation component and the lamp body facilitates maintenance and replacement, improving the product's practicality and convenience.

[0025] Optionally, the light-emitting module further includes a light-transmitting panel, which is mounted on the bottom of the lower structural plate.

[0026] By adopting the above technical solution, the light-transmitting panel is installed at the bottom of the lower structural plate, which effectively protects the lamp body and other components in the light-emitting module, preventing dust and foreign objects from entering. It also optimizes the light projection effect, making the illumination more uniform and softer. Furthermore, the light-transmitting panel enhances the overall aesthetics of the structure and improves the decorative effect of the sound-absorbing chandelier.

[0027] The upper structural plate includes a mounting base, a mounting plate, and a closing plate. The mounting plate is connected to the outer shell through the connecting plate. The closing plate is placed above the mounting plate. A suspension rope is connected to the top of the upper structural plate. The top end of the suspension rope is connected to the mounting base. The mounting plate and the closing plate have circular holes for the suspension rope and the power cord to pass through.

[0028] By adopting the above technical solution, this design makes the chandelier structure more stable, while facilitating the arrangement and fixing of the hanging rope and power cord, thus improving the convenience of installation and the overall aesthetics. The cooperation between the mounting base and the hanging rope ensures the stable suspension of the chandelier, the round hole design facilitates the routing of the power cord and hanging rope, avoiding messy exposed wiring, and the enclosed plate enhances the sealing of the top of the chandelier, effectively preventing dust from entering the internal structure.

[0041] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0042] Example 1

[0043] refer to Figures 1-2 This application discloses a sound-absorbing chandelier.

[0044] A sound-absorbing pendant light includes a housing 1, a sound-absorbing structural layer 2, and a light-emitting module 3.

[0045] The housing 1 includes an outer shell frame 11, an upper structural plate 12 and a lower structural plate 13, wherein the lower structural plate 13 is located at the bottom of the outer shell frame 11 and the upper structural plate 12 is disposed at the top of the outer shell frame 11.

[0046] The sound-absorbing structural layer 2 is disposed within the outer shell frame 11;

[0047] The light-emitting module 3 is mounted on the lower structural plate 13.

[0048] The outer shell frame 11 is connected to the outside via the upper structural plate 12. The sound-absorbing structural layer 2 is disposed inside the outer shell frame 11, and the light-emitting module 3 is mounted on the lower structural plate 13. Specifically, the mounting plate 122 is connected to the mounting base 121 via a suspension rope 4. The mounting plate 122 and the lower structural plate 13 are connected via a connecting strip 113, which has a groove. The outer shell 111 is further connected to the mounting plate 122 and the lower structural plate 13 via the connecting plate 112. Finally, the sealing plate 123 is placed on the mounting plate 122 to form a closed structure. The power cord 32 passes through the round hole of the lower structural plate 13 and connects to the lamp body 31 to provide power. The lamp body 31 is connected to the lower structural plate 13 via a heat dissipation component 33, and a light-transmitting panel 34 is snapped into the lower part of the lamp body 31. When receiving noise, the inner wall of the outer casing 111 is provided with a first sound-absorbing layer 21, and the outer casing 111 is made of sound-absorbing material. Furthermore, both the outer casing 111 and the sound-absorbing structural layer 2 are arc-shaped plates.

[0049] refer to Figure 2A suspension rope 4 is fixedly connected to the mounting plate 122, and a circular hole is provided on the sealing plate 123 for the suspension rope 4 to pass through. The suspension rope 4 passes through the circular hole of the sealing plate 123 and connects to the mounting base 121, thereby fixing the lamp in the usage scenario. A power cord 32 is connected to the lamp body 31. The power cord 32 passes through the circular holes on the mounting plate 122 and the sealing plate 123 to provide power to the light-emitting module 3. Specifically, the outer shell 111 is made of sound-absorbing cotton material, and the first sound-absorbing layer 21 attached to the inner wall is an embedded microporous foam plastic layer.

[0050] refer to Figure 2-3 The power cord 32 connects to the lamp body 31 of the light-emitting module 3. The lamp body 31 provides the light source. The lamp body 31 is connected to the lower structural plate 13 through the heat dissipation component 33. A light-transmitting panel 34 is sandwiched in the middle. Specifically, the light-transmitting panel 34 is a specially made high-transparency, low-refractive-index optical-grade material, which is responsible for evenly distributing the light and preventing glare. The lower structural plate 13 is made of professional sound-absorbing material with a large number of fine perforations, which is used to weaken the secondary vibration energy transmitted and thus play a quiet role.

[0051] The implementation principle of this embodiment is as follows: When using the sound-absorbing pendant light, it is fixed by the hanging rope 4 and the mounting base 121, and the power cord 32 provides power to the light-emitting module 3. When external noise is generated, the noise is reduced by the arc-shaped outer shell 111 made of sound-absorbing cotton material. Furthermore, the first sound-absorbing layer 21, which is composed of an embedded microporous foam plastic layer, is attached to the inner wall of the outer shell 111 to further absorb the noise.

[0052] Example 2

[0053] refer to Figures 4-7 Compared to Embodiment 1, this embodiment features a multi-layer sound-absorbing structure. Specifically, the first sound-absorbing layer 21, made of porous sound-absorbing material, absorbs high-frequency noise. The resonator of the acoustic interference structure 221 on the second sound-absorbing layer 22 absorbs mid-to-low-frequency noise. The first and second sound-absorbing layers 21 and 22 are interconnected to form a sound-insulating cavity 23. The surface of the second sound-absorbing layer 22 facing the sound-insulating cavity 23 is covered with a sound-absorbing coating. The sound-insulating cavity 23 is filled with sound-absorbing fibers or honeycomb structure material to further isolate the sound propagation path. The first sound-absorbing layer 21, the second sound-absorbing layer 22, and the sound-insulating cavity 23 form a multi-layer sound-insulating structure. This multi-layer sound-insulating structure has wide-band noise reduction performance and achieves high-efficiency absorption of external noise. The sealing plate 123 and the lower structural plate 13 are both made of microporous sound-absorbing material, which improves the sound absorption effect of the lamp while providing sealing and fixing functions. The contact surface between the heat dissipation component 33 and the lamp body 31 is coated with thermally conductive silicone grease, which significantly improves the heat conduction efficiency, reduces the temperature of the lamp body 31 during operation, thereby extending the service life of the lamp body 31 and ensuring its stable operation.

[0054] The implementation principle of this embodiment is as follows: In actual use, when external noise is generated, the sound-absorbing chandelier, through its multi-layer sound-absorbing structure design, absorbs high-frequency noise through a porous sound-absorbing material in the first sound-absorbing layer 21, while the resonator of the acoustic interference structure 221 on the second sound-absorbing layer 22 absorbs mid-to-low-frequency noise. The first and second sound-absorbing layers 21 and 22 are interconnected to form a sound-insulating cavity 23, which is filled with sound-absorbing fibers or honeycomb structure material to further isolate the sound propagation path. The first sound-absorbing layer 21, the second sound-absorbing layer 22, and the sound-insulating cavity 23 form a multi-layer sound-insulating structure. This multi-layer sound-insulating structure has wide-band noise reduction performance, achieving a high-efficiency absorption effect for external noise. At the same time, the scientific layout of the light-emitting module 3 and the supporting heat dissipation measures ensure the stable operation of the lamp for a long time, thereby achieving efficient noise reduction and high-quality lighting effects.

[0055] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
