[0017] During the use of existing lighting structures, uneven light distribution often occurs, with some areas being too bright and others too dim. This uneven lighting can cause glare, affecting the lighting effect and user experience. Especially in situations where high light uniformity is required, such as ambient lighting design for devices like speakers, a balance between light uniformity and cost must be considered, and traditional lighting structures are often insufficient to meet these practical needs.

[0018] In view of this, the present invention provides a lighting structure that aims to solve the problems of uneven light distribution and glare caused by existing lighting structures, thereby improving the uniformity of lighting and user experience.

[0019] Please see Figure 1 The lighting structure 100 can be applied to various devices that require atmosphere creation or lighting functions, such as speakers, table lamps, and ambient lights, and is especially suitable for scenarios with high requirements for light uniformity and visual comfort.

[0020] Please see Figure 2 and Figure 4 The lighting structure 100 includes a light-emitting component 1, which includes a light-emitting element 11. The light-emitting element 11 can be an LED bead, an OLED light-emitting sheet, or other light-emitting components that provide a basic light source. The light-emitting component 1 typically also includes a circuit board 12. The light-emitting element 11 can be fixed to the circuit board 12 by soldering, surface mounting, or other methods. The circuit board 12 provides power support and control signals to the light-emitting element 11 to enable functions such as turning it on, off, adjusting its brightness, and switching its color.

[0021] The lighting structure 100 also includes a light-diffusing element 2, which is disposed on the light path of the light-emitting element 11 to homogenize the light emitted by the light-emitting element 11. The light-diffusing element 2 includes a light-transmitting body 21, which is made of a high-transmittance material, such as acrylic or PC, to ensure efficient light transmission. Of course, the light-transmitting body 21 can also be doped with a diffusing agent or have microstructures to further enhance the light scattering effect. Simultaneously, a light-diffusing protrusion 22 protrudes from the side of the light-transmitting body 21 facing the light-emitting element 11. This light-diffusing protrusion 22 corresponds to the position of the light-emitting element 11, and its main function is to diffuse the light emitted by the light-emitting element 11, making the light more dispersed during propagation, thereby avoiding excessive local light concentration and the generation of glaring spots. The shape, height, and distribution of the light-diffusing protrusion 22 can be adjusted according to the actual light uniformity requirements.

[0022] The principle of light uniformity in this lighting structure 100 is as follows:

[0023] First, the light-emitting element 11 (such as LED beads or OLED light-emitting sheets) serves as the basic light source. Its point light source or local surface light source characteristics determine that the initial light is concentrated and radiated with a strong center and weak edges. The light easily forms a high-intensity bright spot in the direct-light area, while the light attenuates quickly in the surrounding area, which is the root cause of uneven light distribution. At this time, the circuit board 12 only provides power and control signals and cannot change the light propagation characteristics. It is necessary to rely on the intervention of the light-diffusing element 2 for regulation.

[0024] Next, the light-diffusing protrusion 22 in the light-diffusing element 2, which is precisely positioned to correspond with the light-emitting element 11, takes effect first: when the concentrated light emitted by the light-emitting element 11 is incident on the light-diffusing protrusion 22, the specific protrusion shape of the protrusion, such as its arc or trapezoid, will utilize optical refraction and scattering effects to break the unidirectional concentrated propagation path of the light. When the light passes through the surface of the protrusion with different curvatures, it will be deflected in multiple directions. The high-intensity light that was originally focused at one point is decomposed into low-intensity dispersed beams, initially eliminating the glaring bright spots generated by direct light from the light source, and completing the first homogenization. Furthermore, the height and distribution density of the light-diffusing protrusion 22 can be adjusted according to the power and uniformity requirements of the light-emitting element 11. For example, for high-brightness LEDs, the height of the protrusion can be increased to enhance the diffusion effect, ensuring compatibility with different light source characteristics.

[0025] Subsequently, the light that has undergone initial diffusion enters the light-transmitting body 21 and undergoes a second homogenization: on the one hand, the fine frosted texture, micro-bumps, and other optical microstructures that may exist inside the light-transmitting body 21, or the slight light scattering characteristics of the material itself, will cause the dispersed light to undergo multiple diffuse reflections inside the body, further weakening the directionality of the light and avoiding secondary aggregation caused by the consistent propagation direction; on the other hand, the thickness and shape (such as flat or curved) of the light-transmitting body 21 are designed to make the propagation distance of light incident at different positions within the body tend to be consistent, reducing the uneven intensity attenuation caused by differences in propagation paths, and ultimately forming a light field with uniform intensity inside the body.

[0026] Finally, the balanced light field is stably emitted from the light-emitting surface of the light-transmitting body 21. At this time, the light is evenly distributed on the entire light-emitting surface, with no obvious bright areas, dark areas or light-dark boundaries. The light is soft and the coverage is uniform, which solves the problems of local glare and overall unevenness of traditional lighting structures 100.

[0027] In summary, the lighting structure 100 provided in this embodiment of the invention includes a light-emitting component 1 and a light-diffusing component 2. The light-emitting component 1 includes a light-emitting element 11; the light-diffusing component 2 is disposed on the light path of the light-emitting element 11; the light-diffusing component 2 includes a light-transmitting body 21 and a light-diffusing protrusion 22 protruding on the side of the light-transmitting body 21 facing the light-emitting element 11. The light-diffusing protrusion 22 is disposed corresponding to the light-emitting element 11 and is used to diffuse the light emitted by the light-emitting element 11. By providing a light-diffusing protrusion 22 corresponding to the light-emitting element 11 on the side of the light-transmitting body 21 facing the light-emitting element 11, this embodiment of the invention utilizes the protrusion to initially diffuse the light, and then combines this with the light-transmitting characteristics of the light-transmitting body 21 to achieve secondary light homogenization, thus solving the problems of uneven light distribution and glare in traditional lighting structures 100, and improving the uniformity of lighting and user experience.

[0028] In some embodiments, please refer to Figure 4 In order to improve the curvature difference of the surface of the uniform light convex portion 22, the convex height of the uniform light convex portion 22 is gradually increased from the edge to the center.

[0029] This makes the light-diffusing convex part 22 form a gradient structure similar to a convex lens. When light shines from the light-emitting element 11 onto the light-diffusing convex part 22, the convex height of the edge region 222 is lower and the refraction angle of the light is smaller, while the convex height of the central region is higher and the refraction angle is larger. This refraction effect that gradually increases from the edge to the center allows the light to diffuse in a stepped manner from the center to the surrounding areas, avoiding excessive concentration of light in the central region.

[0030] In some embodiments, please continue reading Figure 4 To enhance the diffusion of light to the light-emitting element 11 and the core area, the part of the light-dispersing convex portion 22 with the largest protrusion height is positioned opposite to the light-emitting surface of the light-emitting element 11.

[0031] This allows the central beam of light with the highest intensity emitted by the light-emitting element 11 to directly act on the area with the largest curvature of the uniform light convex part 22. Through the stronger refraction and scattering effect in this area, the core strong light is fully diffused, effectively avoiding local bright areas formed by direct light. At the same time, the lower height of the convex part of the edge area 222 moderately guides the weak light, further improving the uniformity of the overall light.

[0032] In some embodiments, please refer to Figure 4 To further enhance the uniformity of light, directional diffusion of light was controlled. Specifically, the outer surface of the central region 221 of the light-diffusing convex portion 22 was made into a spherical surface, and the outer surface of the edge region 222 of the light-diffusing convex portion 22 was made into an arc surface; and the curvature direction of the spherical surface was opposite to that of the arc surface.

[0033] From an optical perspective, the spherical surface in the middle of the uniform light convex portion 22 (usually designed to be curved toward the light-emitting element 11) has a more regular and concentrated curvature characteristic. When high-intensity light from the center of the light-emitting element 11 is incident, the spherical surface can completely decompose the originally focused strong light into diffuse weak light through multi-directional and highly uniform refraction and scattering effects. Moreover, the arc-shaped structure of the spherical surface can ensure that the angle of light diffusion in all directions is more balanced, avoiding the occurrence of diffusion dead angles. The curvature direction of the arc surface of the edge region 222 (designed to be curved away from the light-emitting element 11) is opposite to that of the spherical surface, and its main function is to guide.

[0034] When low-intensity light from the edge of the light-emitting element 11 is incident on the edge area, the reverse-curved arc surface will generate a slight refractive force that converges the light towards the central area, compensating for the problem of excessively rapid attenuation that easily occurs when the edge light propagates naturally. This allows the edge light, which may have been too dispersed, to complement and superimpose with the light diffused in the center, ultimately achieving a uniform light intensity across the entire light-emitting surface of the light-transmitting body 21.

[0035] In some embodiments, please continue reading Figure 4 To avoid sudden deflection or interruption of light propagation, the outer surface of the central region 221 of the light-diffusing convex portion 22 is set as a spherical surface, and the outer surface of the edge region 222 of the light-diffusing convex portion 22 is set as an arc surface; and the spherical surface and the arc surface are smoothly connected.

[0036] It is understandable that if there are steps, sharp edges, or obvious abrupt changes in angle at the junction, light will be abnormally deflected when passing through the junction due to the interface change, which may form local dark lines or bright spots and destroy the initial homogenization effect. On the other hand, a smooth transition allows the curvature of the surface to change continuously from a sphere to an arc, and the propagation path of light in the transition area is natural and smooth, without sudden deflection or interruption of propagation, ensuring that the diffusion effect of the entire uniform light convex part 22 on the light is continuous and uniform.

[0037] In some embodiments, please continue reading Figure 4 To further enhance the uniformity of light, the directional diffusion of light is further controlled. Specifically, the outer surface of the central region 221 of the light-diffusing convex portion 22 is set as a spherical surface, and the outer surface of the edge region 222 of the light-diffusing convex portion 22 is set as an arc surface; and the radius of curvature of the spherical surface is made larger than the radius of curvature of the arc surface.

[0038] From the perspective of optical principles, the radius of curvature is inversely proportional to the refractive intensity of the surface: the smaller the radius of curvature, the higher the curvature of the surface (the greater the curvature), and the stronger the refraction and scattering effect of light; conversely, the larger the radius of curvature, the smoother the surface (the smaller the curvature), the gentler the refraction effect, but the more uniform the diffusion range. The spherical surface in the middle of the uniform light convex part 22 corresponds to the high-intensity light at the center of the light-emitting element 11. Its large radius of curvature (gentle curved surface) can achieve uniform and non-excessive diffusion: when strong light is incident on the spherical surface, the gentle curved surface will not cause the light to be drastically deflected. Instead, it will diffuse the concentrated light smoothly to all sides through uniform refraction with a large area and low curvature. This avoids the formation of dark spots in the central area due to excessive dispersion of light caused by excessive refraction, and also ensures the uniformity of diffusion. The arc surface of the edge region 222 corresponds to the weak light at the edge of the light-emitting element 11. Its smaller radius of curvature (more curved surface) can provide stronger refraction guidance: the weak light itself has low energy. If the refraction is too weak, it is easy to form dark areas due to propagation attenuation. The arc surface with a smaller radius of curvature can actively change the propagation direction of the weak light through a stronger refraction effect, and guide some of the edge light to the central region 221 to fill the light density gap after the diffusion of strong light in the center, while avoiding dark areas at the edge caused by the natural attenuation of weak light.

[0039] That is, by setting the radius of curvature of the spherical surface to be greater than that of the arc surface, the light-monopolizing convex part 22 can differentiate the light of different intensities emitted by the light-emitting element 11: the central spherical surface treats strong light with gentle diffusion to avoid the center being too bright or too dark; the edge arc surface guides weak light with strong refraction to fill the gap in the central light. The two work together to further enhance the uniformity of light in the light-transmitting body 21.

[0040] It should be noted that the above embodiments can be combined arbitrarily to meet diverse needs. For example, in high-end ambient lighting where light uniformity is extremely important, the gradient height design of the light-averaging protrusion 22, the reverse bending structure of the spherical and arc surfaces, and the smooth transition connection can be used simultaneously to achieve a near-ideal light uniformity effect through multiple light-averaging optimization methods. In contrast, in cost-sensitive ordinary table lamps, only the basic light-averaging protrusion 22 and the light-transmitting main body 21 structure can be retained. Under the premise of cost control, the uniformity requirements of daily lighting can be ensured by reasonably designing the distribution density and protrusion height of the light-averaging protrusion 22. Furthermore, the combination of different embodiments can adapt to light-emitting elements 11 of different sizes and shapes. When the light-emitting element 11 is a long strip LED light strip, the light-diffusing protrusion 22 can be designed as a long strip structure consistent with the extension direction of the light strip. Combined with the design of gradual height and curvature radius differences, it can be ensured that the light emitted from each part of the light strip can be effectively uniform. If the light-emitting element 11 is an array of LED beads, an independent light-diffusing protrusion 22 can be set for each bead. By adjusting the spacing and shape of adjacent protrusions, dark areas are avoided at the gaps between the beads, thereby achieving uniform light emission from the entire light-emitting surface. This flexible combination method makes the lighting structure 100 widely applicable and scalable, and can be optimized according to the specific requirements of actual application scenarios.

[0041] In some embodiments, please refer to Figure 2 and Figure 3 Considering the scenario where multiple light-emitting elements 11 are arranged along a certain direction, to avoid the problems of "bright spots formed by overlapping light from adjacent light sources" or "dark areas formed by insufficient light between light sources," the spacing between the light-emitting elements 11 and the light-diffusing protrusion 22 has been optimized. Specifically, the light-emitting elements 11 are arranged along a first direction (this first direction can be a straight line, curve, broken line, ring, rectangular ring, etc., which can be understood as...). Figure 2 and Figure 3 The first direction shown is a ring. ) Each has multiple light-diffusing elements 2, including multiple light-diffusing protrusions 22 arranged along the first direction. The multiple light-diffusing protrusions 22 and the multiple light-emitting elements 11 are arranged in a one-to-one correspondence. The distance between the light-diffusing protrusion 22 and the corresponding light-emitting element 11 is equal to 0.7 to 0.8 times the distance between the light-emitting elements 11.

[0042] This spacing design is based on the optical superposition and attenuation principle: when the spacing is too small (less than 0.7 times the spacing of the light-emitting elements 11), the light diffused from adjacent light-averaging protrusions 22 superimposes prematurely during propagation, easily forming a bright band of superimposed light intensity in the middle area between the two protrusions, thus disrupting the overall uniformity; while when the spacing is too large (greater than 0.8 times the spacing of the light-emitting elements 11), the light diffused from the light-averaging protrusions 22 attenuates due to the excessive propagation distance, failing to effectively cover the gap area between the light-emitting elements 11, easily forming dark areas. By controlling the spacing to 0.7 to 0.8 times the spacing of the light-emitting elements 11, the light diffused from adjacent light-averaging protrusions 22 can achieve balanced superposition of intensity when it propagates to the center position of the gap between the light-emitting elements 11, avoiding bright spots caused by excessive superposition and filling the light gap in the gap area, ensuring that multiple light-emitting elements 11 arranged along the first direction form a continuous and uniform light band under the action of the light-averaging element 2. For example, when the light-emitting elements 11 are arranged at equal intervals along a straight line (with a spacing of 9.9 mm), the distance between the light-diffusing convex part 22 and the light-emitting element 11 can be set to 7.3 mm (i.e., a distance between 0.7 and 0.8 times 9.9 mm). At this time, when the light diffused by each light-diffusing convex part 22 reaches the middle position of the adjacent light-emitting element 11, the intensity is exactly attenuated to be equal to the intensity of the light diffused by the adjacent convex part. The two are superimposed to form a uniform light intensity, avoiding the generation of bright bands or dark areas.

[0043] Furthermore, for example, the radius of curvature of the sphere is 0.3 times the first spacing; the radius of curvature of the arc surface is 0.2 times the first spacing. For the high-intensity light from the center of the light-emitting element 11, the sphere with a radius of curvature of 0.3 times the first spacing can form a smooth and uniform refractive surface. Taking a first spacing of 7.3 mm (corresponding to a spacing of 9.9 mm between light-emitting elements 11) as an example, the radius of curvature of the sphere is approximately 2.2 mm. At this size, after strong light is incident, it will be deflected in multiple directions with low intensity along the sphere. This avoids excessive light dispersion due to an overly steep curvature (avoiding a dark spot in the center) and insufficient diffusion due to an overly smooth curvature (avoiding a bright spot in the center), thus achieving uniform dispersion of strong light. Arc surface (radius of curvature = 0.2 × first spacing): enhancing the directional guidance of weak light. For the weak light at the edge of the light-emitting element 11, the arc surface with a radius of curvature of 0.2 times the first spacing (approximately 1.5 mm in the same example above) makes the curvature of the surface more pronounced and the refractive intensity stronger. When weak light is incident, the stronger refraction effect can actively guide the light to the center of the uniform light convex part 22, accurately fill the light density gap that may occur after the strong light diffuses on the spherical surface, and at the same time avoid the formation of edge dark areas due to the natural attenuation of weak light, forming a synergistic effect of central diffusion and edge supplementation with the spherical surface.

[0044] In some embodiments, please refer to Figure 4In order to further enhance the uniformity of light during the light emission stage and avoid local brightness differences on the light emission surface of the light-transmitting body 21, the side of the light-transmitting body 21 away from the light-emitting element 11 is convex and concave to form a scattering texture 211, which corresponds to the light-averaging convex part 22.

[0045] These scattering textures 211 can be regularly arranged microprism structures, irregular frosted particles, or periodically varying concave-convex textures. Their density and depth can be adjusted according to the thickness of the light-transmitting body 21 and the size of the light-emitting surface. When the uniform light field, after secondary homogenization, shines from the interior of the light-transmitting body 21 onto the light-emitting surface, the scattering textures 211 perform a third fine homogenization of the light: as the light passes through the concave-convex interfaces at different depths and angles, it undergoes multi-directional and multi-angle micro-refraction and reflection, further smoothing out any potential subtle intensity differences and significantly improving the brightness uniformity of the light-emitting surface. Simultaneously, the design of the scattering textures 211 softens the light emission angle, making the emitted light more gentle and avoiding glare caused by directional reflections due to the flatness of the light-emitting surface, further enhancing the user's visual comfort. For example, in the design of children's eye-protection lamps, the scattering textures 211 can be set as dense, tiny arc-shaped protrusions, effectively scattering light while maintaining the soft texture of the light-emitting surface, reducing stimulation to children's eyes.

[0046] In some embodiments, please continue reading Figure 4 The diffuse reflection effect of light is further enhanced by the microstructure, which improves the softness and uniformity of the light surface. The scattering texture 211 includes multiple pearlescent dots, which are arc-shaped protrusions that are raised along the surface of the light-transmitting body 21 away from the light-diffusing protrusion 22.

[0047] The curved surfaces of these pearlescent dots can be designed as micro-convex structures with radii between 0.05 mm and 0.2 mm, and the spacing between adjacent pearlescent dots is controlled within the range of 0.1 mm to 0.3 mm, forming a dense and uniform distribution. When light shines from inside the light-transmitting body 21 onto the pearlescent dots, each curved protrusion is equivalent to a miniature diffuse reflection unit: the light undergoes multi-angle refraction and reflection at the curved interface, with some light rays perpendicularly pointing towards the light-emitting direction and others scattering in all directions. Through the synergistic effect of a large number of pearlescent dots, any subtle differences in brightness that might have existed are completely eliminated, and the light-emitting surface exhibits a soft texture similar to frosted glass. At the same time, the curved design of the pearlescent dots avoids the formation of sharp optical interfaces, reduces energy loss of light at the interface, and ensures the efficiency of light emission.

[0048] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4To make the light reflect laterally outward, a ring-shaped skirt cover 3 is added. The skirt cover 3 includes a reflective part 31, and the scattering texture 211 is arranged in a ring shape. The reflective part 31 extends from the inner ring area of ​​the scattering texture 211 in a direction away from the light-emitting element 11, and the outer periphery of the reflective part 31 is recessed inward.

[0049] The phrase "the outer periphery of the reflective part 31 is concave" can be understood as the outer periphery of the reflective part 31 having an arc-shaped concave structure. This design allows vertical light rays emitted from the inner ring region of the scattering texture 211 to be concentratedly reflected on the concave surface of the reflective part 31. When light rays strike the reflective part 31 at a large angle, the concave arc-shaped surface reflects them outward, effectively widening the lateral coverage of the light. Simultaneously, the curvature of the concave surface can be adjusted according to actual needs. By optimizing the radius of curvature, the diffusion angle of the reflected light can be controlled, avoiding the formation of local bright or dark areas due to excessive reflection and ensuring the uniformity of lateral light emission.

[0050] This recessed design makes the reflector 31 form a structure similar to a concave mirror. When light shines on the outer surface of the reflector 31, the recessed area can converge the light inward and reflect it laterally, guiding some of the light that might have propagated downward to the lateral light output direction, thereby enhancing the illumination range and intensity of the light structure 100 in the horizontal direction. At the same time, the reflector 31 works in conjunction with the annular arrangement of the scattering texture 211. After the light homogenized by the scattering texture 211 is reflected by the reflector 31, the lateral light output maintains uniformity, and the structural design of the reflector 31 avoids scattering of light to non-target areas, thus improving the efficiency of light utilization.

[0051] In some embodiments, please refer to Figure 1 and Figure 2 In order to concentrate the light in a specific area and improve the utilization rate of the light, a housing 4 for blocking the light is added. Specifically, the housing 4 is fitted around the light diffuser 2 and the light-emitting component 1 is hidden inside the housing 4; the reflective part 31 extends out relative to the housing 4.

[0052] The outer casing 4 not only effectively blocks the direct glare generated by the light-emitting component 1, improving the product's aesthetics and safety, but also, through the reflective treatment of the inner wall (such as using a high-reflectivity metal coating or a white matte material), reflects some stray light that is not utilized by the light-diffusing component 2 and the light-transmitting body 21 back into the light-transmitting body 21 for secondary utilization, further improving the efficiency of light utilization. The design of the reflector 31 extending out of the outer casing 4 ensures that the lateral light guided by it can be emitted towards the target area without being blocked by the outer casing 4, concentrating the light on the specific area requiring illumination and avoiding energy loss caused by unnecessary scattering of light into the inner casing 4.

[0053] In some embodiments, please refer to Figure 2and Figure 3 Considering that the light reflected by the reflector 31 into the air is rather monotonous, a light guide 5 is added. Specifically, the light guide 5 is connected to the end of the reflector 31 away from the light-emitting element 11 to receive the light emitted by the scattering texture 211 and emit it laterally.

[0054] The light guide 5 can be made of high-transmittance materials such as acrylic, PC, and silicone. Its interior can be set with continuous microstructured light guide dots or linear light guide stripes. These microstructures can directionally guide and homogenize the incident light. When the light emitted by the scattering texture 211 enters the light guide 5, the light guide 5 converts the axial transmission of the light into lateral emission through the principle of total internal reflection: when the light propagates inside the light guide 5, it will undergo local refraction and scattering when it encounters the microstructure dots or stripes, causing some of the light to change its propagation direction and be uniformly emitted from the side of the light guide 5; at the same time, the light not affected by the microstructure continues to propagate along the axial direction of the light guide 5 until it is guided out by subsequent microstructures, thus achieving a uniform distribution of light along the length of the light guide 5. Furthermore, the light-emitting surface of the light guide 5 can be further designed as a frosted surface or have a diffusion film layer added to finally homogenize the laterally emitted light, ensuring that the emitted light is both soft and uniform, avoiding local bright lines or dark areas.

[0055] This combination of light guide 5 and reflector 31 not only enriches the form of light emission, expanding the originally single reflected light into a composite light field with the synergistic effect of reflection and light guiding, but also allows for precise control of the range and angle of lateral light emission through the customization of the length and shape of light guide 5, meeting the specific needs of the illumination area in different scenarios.

[0056] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 To achieve a compact and stable structure for both the light guide 5 and the reflective portion 31 of the skirt 3 while fulfilling their respective functions, their structures have been optimized. Specifically, the skirt 3 also includes an annular mounting portion 32, the annular end face of which is in contact with the annular end face of the reflective portion 31 away from the light-emitting element 11; the light guide 5 is annular, with its inner annular surface attached to the outer annular surface of the mounting portion 32.

[0057] The mounting part 32 provides a stable assembly base for the light guide 5. The precise alignment of its annular end face with the reflector 31 ensures the structural continuity and stability of both, preventing light leakage or structural loosening due to assembly gaps. Simultaneously, the cooperation between the annular light guide 5 and the annular mounting part 32 enables the lateral light output to form a uniform 360-degree halo effect, further expanding the application possibilities of the light structure 100 in ambient lighting scenarios.

[0058] In some embodiments, please continue reading Figure 2 , Figure 3 and Figure 4 To improve the feel of the light guide 5, the light guide 5 is made of silicone.

[0059] Silicone material possesses excellent flexibility and a pleasant tactile feel. Its surface is smooth and delicate, providing a soft texture that users can experience upon touch, effectively avoiding the cold and harsh feel that traditional rigid light guide materials may provide. Simultaneously, the elastic properties of silicone allow the light guide component 5 to have a certain cushioning effect, enhancing the protection of the light structure 100.

[0060] This invention also provides a speaker.

[0061] Please see Figures 1 to 4 In any of the above figures, the speaker includes the lighting structure 100 in any of the above embodiments, combining the lighting structure 100 with the speaker's sound-emitting function to achieve an integrated audio-visual user experience. For example, when the speaker plays music, the lighting structure 100 can automatically adjust the color, brightness, flashing frequency, and uniformity of the light according to the rhythm, melody, or volume changes of the music, enhancing the music's appeal through dynamic changes in light and shadow. Specifically, when playing soothing light music, the lighting structure 100 can output soft and uniform warm-toned light through the synergistic effect of the uniform light protrusion 22 and the light-transmitting body 21, creating a warm and tranquil atmosphere; while when playing high-energy rock music, the lighting structure 100 can adjust the brightness change frequency of the light-emitting element 11, and in conjunction with the reflective part 31 of the skirt 3 and the light guide 5, make the horizontally emitted light present a dynamic flashing effect synchronized with the music beat, and through the homogenization treatment of the scattering texture 211 and pearlescent dots, ensure that the light remains uniform and soft during the flashing process, avoiding glare stimulation caused by frequent brightness changes. In addition, the speaker housing 4 can be integrated with the housing 4 of the lighting structure 100, hiding the light-emitting component 1, the light diffuser 2 and the light guide 5 inside the speaker, leaving only the reflector 31 and the light guide 5 exposed. This not only ensures the overall aesthetics of the speaker, but also further improves the light utilization efficiency through the shielding of the housing 4 and the reflection treatment of the inner wall.
