Description

Technical Field

[0001] This application relates to the field of audio-visual equipment for television sets, such as a lamp module and a television set. Background Technology

[0002] With the continuous development of television technology, users' demands for viewing experience are increasing. Adding corresponding light effects and interactive functions to televisions when playing music or movies, so that the lights change with the rhythm of the audio, can significantly enhance the viewing atmosphere and is gradually becoming a new market demand.

[0003] Currently, some products have attempted to combine sound pickup with ambient lighting effects. For example, sound pickup sensors and LED light sources are integrated into televisions or peripheral devices, and the color or brightness of the light dynamically changes according to the audio signal to create an audio-visual fusion atmosphere.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: In related technologies, the light guiding and sound guiding functions of existing ambient sound pickup modules are usually integrated into the same component and share the same internal space. They are mainly designed for microphone pickup scenarios and do not have independent channel structures on the light transmission path and the sound transmission path. As a result, when such structures are applied to TV lamp modules, the light effect and sound output interfere with each other on the module surface, making it difficult to achieve compatibility between large-area light effect and efficient sound output without adding an additional speaker module.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] This disclosure provides a lamp module and a television set, which effectively solves the problem that in a television lamp module, light effect and sound output interfere with each other on the module surface, making it difficult to achieve compatibility between large-area light effect and high-efficiency sound output without adding an additional speaker module.

[0008] This disclosure provides a lamp module, including: a support member having a cavity extending along its length, and a through-hole area on the side wall of the support member; a light source disposed on the side of the support member away from the through-hole area and emitting light towards the cavity; at least two vertical ribs disposed within the cavity and located on both sides of the light source along its width, the vertical ribs defining sound inlets communicating with the cavity on both sides of the light source; a light guide member, at least partially transparent, disposed within the cavity, and a gap channel defined between the outer wall of the light guide member and the inner wall of the cavity; light emitted from the light source passes through the light guide member and exits through the through-hole area, and external sound enters the gap channel through the sound inlets and then exits through the through-hole area.

[0009] In some embodiments, the support member is a strip lamp holder with a V-shaped cross-section, the V-shaped tip pointing away from the light source, and the opening facing the light source.

[0010] In some embodiments, two vertical ribs extend along the length of the support member, and the area between the two vertical ribs is used to accommodate and fix the light source.

[0011] In some embodiments, the light source includes a circuit board carrier and a plurality of LED beads arranged at intervals along the length of the support member, and the circuit board carrier is snapped and fixed to a snap-fit ​​structure provided on opposite sides of two vertical ribs.

[0012] In some embodiments, the cavity is an arc-shaped space, the light guide component is an arc-shaped expander, the curvature of the arc-shaped expander matches the curvature of the arc-shaped space, and a gap channel is formed between the outer wall of the arc-shaped expander and the inner wall of the arc-shaped space.

[0013] In some embodiments, the lamp module further includes: a cover covering the front side of the support member; the cover is a steel mesh with a V-shaped cross-section adapted to the cross-section of the support member, and the inner side of the steel mesh is lined with mesh fabric.

[0014] In some embodiments, the support member has end clips at both ends along its length, and the cover has buckles at both ends, with the buckles and end clips being detachably engaged.

[0015] In some embodiments, the lamp module further includes: a plurality of transverse ribs extending along the width direction of the support member, one end of which is connected to the outer side of the vertical rib and the other end of which is connected to the edge of the support member; the plurality of transverse ribs are arranged at intervals along the length direction of the support member; and the gap between adjacent transverse ribs constitutes at least a portion of the sound inlet.

[0016] In some embodiments, the through-hole region is a grid-like through-hole array.

[0017] This disclosure also provides a television set, including a frame and the aforementioned lamp module, wherein the support member of the lamp module is fixed to the outside of the frame.

[0018] The lamp module and television set provided in this disclosure can achieve the following technical effects: This disclosure provides a lamp module, including: a support member having a cavity extending along its length, and a through-hole area on the side wall of the support member; a light source disposed on the side of the support member opposite to the through-hole area, emitting light towards the cavity; at least two vertical ribs disposed within the cavity and located on both sides of the light source along its width, the vertical ribs defining sound inlets communicating with the cavity on both sides of the light source; and a light guide member, at least partially transparent, disposed within the cavity, with a gap channel defined between the outer wall of the light guide member and the inner wall of the cavity; light emitted from the light source passes through the light guide member and exits through the through-hole area, while external sound enters the gap channel through the sound inlets and exits through the through-hole area. In this way, by defining sound inlets communicating with the cavity on both sides of the light source by the vertical ribs, external sound enters the gap channel independently from both sides of the light source, while the light from the light source is longitudinally conducted through the light guide member. Sound and light are transmitted along independent paths within the support member, ultimately radiating from different areas of the through-hole area, effectively avoiding modal interference caused by the sharing of the same channel between sound and light in traditional solutions. The gap channel between the light guide component and the inner wall of the cavity is specially used as a sound transmission path, realizing the separation of the light path inside the light guide component and the sound path through the gap channel. The lamp module does not need to have a built-in speaker, and can complete the efficient sound output by simply using the existing sound source of the TV. It has high integration and compact structure.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0030] This disclosure provides a lamp module and a television set, which effectively solves the problem that in a television lamp module, light effect and sound output interfere with each other on the module surface, making it difficult to achieve compatibility between large-area light effect and high-efficiency sound output without adding an additional speaker module.

[0031] like Figures 1 to 6 As shown, this embodiment of the present disclosure provides a lamp module 12, including: a support member 21 having a cavity extending along its length, and a through-hole area 211 on the side wall of the support member 21; a light source 22 disposed on the side of the support member 21 away from the through-hole area 211 and emitting light towards the cavity; at least two vertical ribs 212 disposed in the cavity and located on both sides of the light source 22 along its width, the vertical ribs 212 defining sound inlets communicating with the cavity on both sides of the light source 22; a light guide member 23, at least partially transparent, disposed in the cavity, and a gap channel defined between the outer wall of the light guide member 23 and the inner wall of the cavity; light emitted by the light source 22 passes through the light guide member 23 and exits through the through-hole area 211, and external sound enters the gap channel through the sound inlet and then exits through the through-hole area 211.

[0032] Specifically, the support member 21 is hollowed out to form a cavity running through its length. The support member 21 has a through-hole area 211, which serves as a shared window for both light emission and sound transmission. The light source 22 is installed on the side of the support member 21 facing away from the through-hole area 211, with its emitting surface facing the interior of the cavity to ensure forward radiation. At least two vertical ribs 212 are provided within the cavity, symmetrically arranged on the left and right sides of the light source 22. The vertical ribs 212 define the gap areas between the sides of the light source 22 and the cavity sidewalls; these gap areas serve as sound inlets, allowing sound waves from the external environment to enter the cavity along these gaps. In the central region of the cavity, in front of the space enclosed by the vertical ribs 212, a light guide component 23 is installed. The light guide component 23 is at least partially transparent, and its outer contour dimension is smaller than the inner contour dimension of the cavity. This means that the outer wall of the light guide component 23 is not completely fitted with the inner wall of the cavity, but rather a gap channel is reserved around the light guide component 23. In this way, the lamp module 12 presents two independent energy conduction paths when it is working. On the one hand, the light emitted from the front of the light source 22 is incident forward to the rear end face of the light guide component 23. After entering the interior of the light guide component 23, it is refracted and scattered, and then uniformly emitted from the front end face of the light guide component 23. Subsequently, it passes through the through-hole area 211 of the side wall of the support component 21 and radiates into the external environment, forming a surface light source 22 effect on the surface of the module. On the other hand, the sound waves radiated by the internal speaker of the television first reach the side of the lamp module 12 away from the through-hole area 211, enter the cavity through the sound inlets on both sides of the light source 22, and then enter the gap channel between the outer wall of the light guide member 23 and the inner wall of the cavity. They are then propagated forward along this gap channel and finally pass through the through-hole area 211 to the external environment. During this process, the light is always transmitted inside the light guide member 23, while the sound waves are transmitted in the gap channel outside the light guide member 23. The two are physically isolated in space and do not interfere with each other, effectively solving the modal interference problem caused by the sharing of the same internal space by sound and light in traditional solutions. In addition, the gap channel formed by the smaller outer contour dimension of the light guide member 23 than the inner contour dimension of the cavity is essentially a tolerance absorption space. During manufacturing and assembly, there will inevitably be deviations between the actual size and installation position of the light guide member 23. This gap channel can absorb these deviations, avoiding hard interference between the light guide member 23 and the inner wall of the cavity, while ensuring the smoothness of the sound wave transmission path. The through-hole area 211 serves as a shared emission window for light and sound. Its aperture and distribution density can be independently adjusted during the design phase, so that the balance of light and sound effects is no longer limited by the internal space partitioning, thus increasing the freedom of design.This configuration achieves parallel integration of light guiding and sound guiding functions within a single module through spatial topology separation. The lamp module 12 itself does not need to have a built-in speaker; it can achieve efficient sound output simply by using the existing sound source inside the TV. From a structural mechanism perspective, this solves the technical problem of mutual interference between sound and light in the existing technology and the difficulty in achieving compatibility between large-area light effect and efficient sound output without adding an additional speaker module.

[0033] In some embodiments, the support member 21 is a strip lamp holder with a V-shaped cross-section, the V-shaped tip pointing away from the light source 22, and the opening facing the light source 22.

[0034] Specifically, the outline of the support member 21 opens outwards from the middle to form two oblique wings, with the V-shaped tips pointing away from the light source 22 and the V-shaped openings facing the light source 22 (i.e., towards the inside of the television). This arrangement, with the V-shaped tips pointing outwards, makes the two oblique wings face the user, increasing the effective projection area towards the user; the V-shaped openings facing inwards increase the internal volume of the cavity, providing more physical space for sound wave diffusion within the cavity. Correspondingly, after reflection and diffusion within the V-shaped cavity, the sound waves radiate outwards from the through-hole areas 211 of the two oblique wings, forming a wider sound field coverage angle in the horizontal direction than a planar structure.

[0035] In some embodiments, two vertical ribs 212 extend along the length of the support member 21, and the area between the two vertical ribs 212 is used to accommodate and fix the light source 22.

[0036] Specifically, two vertical ribs 212 extend continuously along the length of the support member 21, passing through one end of the support member 21 to the other. The area between the two vertical ribs 212 forms a continuous elongated installation space along the length direction, which is used to accommodate and fix the light source 22. The continuous extension of the vertical ribs 212 ensures that the light source 22 is constrained at every point along the length direction, preventing the light source 22 from shifting along the width direction during transportation or use. At the same time, the vertical ribs 212 are half-height structures, that is, they only occupy a portion of the wall thickness in the wall thickness direction of the support member 21, so that sufficient open space is left behind the light source 22, ensuring that sound can smoothly enter the sound inlet from the rear of the light source 22.

[0037] In some embodiments, the length of the vertical rib 212 is the same as the cavity length of the support member 21, and the length of the light source 22 is less than or equal to the length of the vertical rib 212. This arrangement can further enhance the stability of the light source 22 installation.

[0038] In some embodiments, the light source 22 includes a circuit board carrier and a plurality of LED beads arranged at intervals along the length of the support member 21. The circuit board carrier is snapped and fixed on a snap-fit ​​structure 215 provided on opposite sides of two vertical ribs 212.

[0039] Specifically, the light source 22 includes a strip-shaped circuit board carrier and multiple LED beads arranged at intervals along the length of the circuit board carrier. The two sides of the circuit board carrier have snap-fit ​​surfaces, and the opposite sides of the two vertical ribs 212 are provided with corresponding clips or slots. The light source 22 is fixed by snapping into these clips or slots through the two sides of the circuit board carrier. This design eliminates the need for additional fasteners and accessories; operators on the assembly line only need a single pressing action to install and position the light source 22. Furthermore, it can be removed by applying reverse force, facilitating maintenance and replacement.

[0040] In some embodiments, each vertical rib 212 is provided with multiple snap-fit ​​structures 215. The multiple snap-fit ​​structures 215 are spaced apart along the length direction of the vertical rib 212, and can be snapped onto multiple positions along the length direction of the lamp panel. The multiple snap-fit ​​structures 215 of two vertical ribs 212 can be staggered, that is, the gap between one snap-fit ​​structure 215 of one vertical rib 212 and the two snap-fit ​​structures 215 of the other vertical rib 212 is opposite to each other.

[0041] In some embodiments, the cavity is an arc-shaped space, the light guide component 23 is an arc-shaped expander, the curvature of the arc-shaped expander matches the curvature of the arc-shaped space, and a gap channel is formed between the outer wall of the arc-shaped expander and the inner wall of the arc-shaped space.

[0042] Specifically, the cavity is an arc-shaped space with a cross-sectional profile that is either circular or parabolic. The light guide component 23 is correspondingly configured as an arc-shaped expander, meaning it is an arc-shaped transparent plate extending along its length, with its curvature matching the curvature of the arc-shaped space, allowing the expander to be precisely embedded within it. In this configuration, a continuous gap channel is formed between the outer wall of the arc-shaped expander and the inner wall of the arc-shaped space. The width of this gap channel is determined by the dimensional difference between the arc-shaped expander and the arc-shaped space, remaining constant along its length. Furthermore, compared to a rectangular cross-section, the arc-shaped cross-section exhibits a more uniform stress distribution when subjected to external pressure (such as the pre-pressure applied by the cover 24), making it less prone to localized cracking due to stress concentration. Correspondingly, the uniform gap channel ensures consistent sound wave conduction impedance across its length, preventing sound reflection or coloration due to localized narrowing.

[0043] In some embodiments, the lamp module 12 further includes: a cover 24 covering the front side of the support member 21; the cover 24 is a steel mesh 25, the cross-section of the steel mesh 25 is V-shaped to match the cross-section of the support member 21, and the inner side of the steel mesh 25 is lined with mesh.

[0044] Specifically, the cover 24 is a steel mesh 25, the cross-section of which is V-shaped to match the cross-section of the supporting member 21, so that the cover 24, after installation, conforms to the outer surface contour of the supporting member 21, forming a smooth appearance. The inner side of the steel mesh 25 is lined with mesh, which is a thin layer of fabric or metal mesh with sound transmission and dustproof functions. From the perspective of scene mapping, the user's visual first contact is with the surface of the cover 24. The V-shaped steel mesh 25 allows light to pass through evenly from the two sloping surfaces. Combined with the light-diffusing effect of the mesh, it eliminates the graininess of the LED beads and presents a soft linear light band effect. At the same time, the mesh protects the light guide member 23 and the surface of the light source 22 inside the cavity from dust accumulation, extending the optical performance decay period of the lamp module 12 during long-term use.

[0045] In some embodiments, the support member 21 has end clips 213 at both ends along its length, and the cover 24 has buckles 241 at both ends, with the buckles 241 and the end clips 213 detachably engaged.

[0046] Specifically, end clip 213 is a positioning structure protruding from the end face of support member 21, and latch 241 is an elastic hook integrally bent at the end of cover 24. When cover 24 is pressed towards support member 21, latch 241 slides along the guide slope of end clip 213 and finally locks into the slot, emitting a clear click sound. This acoustic feedback can serve as a confirmation signal for proper installation on the assembly line. For disassembly, use a tool to pry latch 241 from the side to detach it from end clip 213. This detachable fit allows cover 24 to be replaced separately during after-sales maintenance, eliminating the need to scrap the entire lamp module 12.

[0047] In some embodiments, the end face of the support member 21 is provided with a plurality of end clips 213, and the end of the cover 24 is provided with a plurality of buckles 241. After the cover 24 is installed on the support member 21, the plurality of buckles 241 can be respectively engaged with the plurality of end clips 213 to further enhance the installation stability.

[0048] In some embodiments, the lamp module 12 further includes: a plurality of transverse ribs 214 extending along the width direction of the support member 21, one end of which is connected to the outer side of the vertical rib 212, and the other end of which is connected to the edge of the support member 21. The plurality of transverse ribs 214 are arranged at intervals along the length direction of the support member 21, and the gap between adjacent transverse ribs 214 constitutes at least a portion of the sound inlet.

[0049] Specifically, multiple transverse ribs 214 are arranged at intervals along the length of the support member 21, and the gaps between adjacent transverse ribs 214 constitute at least a portion of the sound inlet. The transverse ribs 214, vertical ribs 212, and the edges of the support member 21 are preferably integrally injection molded. From a manufacturing process perspective, integral molding avoids secondary assembly processes, and the rib structure can enhance the overall anti-warping stiffness of the support member 21 during the injection molding cooling process. From an acoustic perspective, the gaps between adjacent transverse ribs 214 form an array of sound inlets along the length direction. Sound waves can enter the cavity along multiple inlets dispersed in the height direction. Compared to a single narrow opening, the array of inlets spatially disperses the concentration of incident sound energy, helping to reduce the risk of standing wave resonance at specific frequencies.

[0050] In some embodiments, the through-hole region 211 is a grid-like through-hole array.

[0051] Specifically, the grid-like through-hole array consists of multiple through-holes arranged along the length and width of the support member 21, forming a mesh-like distribution. The mechanical advantage of the grid structure lies in maintaining a large area of ​​light and sound transmission while using a mesh-like rib structure to maintain the structural strength of the front wall of the support member 21, preventing the weakening of the front wall stiffness caused by large-area openings. The aperture and spacing of the through-hole array can be independently optimized according to the target requirements of light and sound effects. Increasing the aperture helps to improve light flux and sound transmittance, while decreasing the aperture helps to increase grid density, enhance structural strength, and improve the appearance.

[0052] This disclosure also provides a television set, including a frame 11 and the above-mentioned lamp module 12, wherein the support member 21 of the lamp module 12 is fixed to the outside of the frame 11.

[0053] Specifically, the lamp module 12 extends along the length of the frame 11, and the back of the support member 21 is attached to the outer side of the frame 11 and fixed by fasteners or adhesive. In this installation configuration, the V-shaped opening of the lamp module 12 faces the inside of the television, allowing the sound emitted by the internal speakers of the television to directly enter the sound inlet on the back of the lamp module 12, resulting in a short path and minimal energy loss. The lamp module 12 is located entirely outside the frame 11, without occupying the space for the mainboard, speakers, and other components inside the television. This achieves decoupling of the sound and light ambient function from the overall structure, meaning that the lamp module 12 can be designed and upgraded independently of the television mainboard without affecting the overall electrical architecture.
