Description

Technical Field

[0001] This invention relates to the field of physiotherapy products technology, and in particular to a lamp panel structure and a physiotherapy waist belt. Background Technology

[0002] Red and blue light therapy is a non-invasive treatment commonly used to relieve muscle soreness, promote blood circulation, and assist in the treatment of inflammation. It is widely applied in healthcare and home therapy devices. Among these, red and blue light therapy belts, as portable therapeutic products, are popular due to their ease of use and comfortable wear. These products typically achieve therapeutic effects through the alternating or synergistic effects of red and blue light, providing deep skin irradiation and tissue stimulation.

[0003] To accommodate the curvature of the human waist and improve wearing comfort, existing red and blue light therapy waist belts generally use flexible printed circuit boards (FPCs) as the carrier for red and blue light emitting components (such as LED beads). FPCs are lightweight, thin, and flexible, and can conform well to the curves of the human body, making them particularly suitable for active areas such as the waist and neck.

[0004] However, due to the lack of sufficient structural support, flexible circuit boards (FPCs) are frequently bent, twisted, or stretched during actual use. When the FPC is subjected to repeated mechanical deformation, stress concentration easily occurs at the solder joints between the LED beads soldered to it and the FPC, leading to fatigue, cracks, or detachment of the soldered structure. This not only reduces the luminous efficiency of the physiotherapy equipment but may also cause some LED beads to fail, resulting in poor therapeutic effects, or even causing the entire circuit to fail, seriously affecting the product's lifespan and user experience. Summary of the Invention

[0005] The primary objective of this invention is to provide a lamp panel structure to ensure the product's lifespan.

[0006] Another objective of this invention is to provide a physiotherapy waist belt employing the above-described lamp panel structure.

[0007] To address the aforementioned technical problems, the present invention provides the following technical solution:

[0008] A lamp panel structure having a first direction and a second direction that intersect perpendicularly includes a flexible circuit board, a support plate, a light-transmitting cover, and red and blue light-emitting components. The flexible circuit board is attached to one side of the support plate, and at least two of the red and blue light-emitting components are spaced apart along the first direction on the flexible circuit board.

[0009] The red and blue light-emitting components include a horizontal light-emitting group and a vertical light-emitting group. At least one horizontal light-emitting group is provided along the second direction, and the horizontal light-emitting group extends along the first direction. The vertical light-emitting group is provided at both ends of the horizontal light-emitting group in the first direction. The vertical light-emitting group extends along the second direction. The flexible circuit board is provided with multiple welding areas. Each welding area is welded with one horizontal light-emitting group or one vertical light-emitting group. The flexible circuit board is also provided with a light-transmitting cover. Each welding area is covered with a light-transmitting cover. The light-transmitting cover is used to restrict the bending of the welding area of ​​the flexible circuit board. There is a gap between two adjacent light-transmitting covers.

[0010] In some embodiments, the support plate has a groove on at least one side in the second direction, and the groove corresponds to the area between two adjacent red and blue light-emitting components.

[0011] In some embodiments, the groove is an arc-shaped groove, and the arc-shaped groove transitions arc-shapedly with the side of the support plate in the second direction.

[0012] In some embodiments, the support plate is provided with grooves on both sides in the second direction, and the groove on one side of the support plate in the second direction corresponds one-to-one with the groove on the other side of the support plate in the second direction. The distance between the bottoms of the two opposite grooves in the second direction is A, in mm, and the distance between the two sides of the support plate in the second direction is B, in mm, wherein 1 / 3≤A / B≤3 / 4.

[0013] In some embodiments, three horizontal light-emitting groups are spaced apart along the second direction, and the two outermost horizontal light-emitting groups located in the second direction are spaced apart from each other on both sides, corresponding to the two ends of the vertical light-emitting group in the second direction.

[0014] In some embodiments, the light-transmitting cover includes a cover body and a connecting plate. The connecting plate is formed by extending outward from the outer periphery of the cover body, and the cover body protrudes from the side of the connecting plate away from the support plate. The connecting plate is attached to the side of the flexible circuit board away from the support plate. The cover body is used to cover the horizontal light-emitting group or the vertical light-emitting group.

[0015] In some embodiments, the lamp panel structure further includes a buffer pad, which is attached to the side of the flexible circuit board away from the support plate, and the buffer pad has clearance openings corresponding to the positions of the horizontal light-emitting group and the vertical light-emitting group.

[0016] In some embodiments, the side of the cushioning pad away from the support plate is flush with the side of the connecting plate away from the support plate.

[0017] In some embodiments, the cushioning pad is a rubber pad, a silicone pad, or a sponge pad.

[0018] In some embodiments, both ends of the light-transmitting cover along its length are arc-shaped.

[0019] In some embodiments, the lamp panel structure further includes a transparent sealing sleeve and a power connection line. The flexible circuit board and the support plate are both located inside the transparent sealing sleeve. One end of the power connection line enters the transparent sealing sleeve and is electrically connected to the flexible circuit board, while the other end of the power connection line extends out of the transparent sealing sleeve.

[0020] In some embodiments, the transparent sealing sleeve is made of PVC material.

[0021] In some embodiments, the support plate is made of PC material.

[0022] In some embodiments, the light-transmitting cover is made of PVC material.

[0023] The present invention also relates to a physiotherapy waist belt, comprising a connecting strap and the aforementioned lamp panel structure. The connecting strap comprises a main body and a connecting part. The main body is provided with the connecting part at both ends along the first direction. One end of each of the two connecting parts is connected to the main body, and the other ends of the two connecting parts are detachably connected together. The main body has a placement space inside. The side of the main body for attaching to the user's body is provided with a light-transmitting element. The lamp panel structure is disposed in the placement space, and the red and blue light-emitting components of the lamp panel structure face the light-transmitting element.

[0024] In some embodiments, the main body portion is further provided with an opening, and a zipper is provided at the opening for opening or closing the opening via the zipper.

[0025] Compared with the prior art, the lamp panel structure of this invention has the following advantages:

[0026] In this invention, by attaching the flexible circuit board to the support plate, the flexible circuit board is supported, thereby restraining its bending, twisting, and stretching, preventing excessive mechanical deformation and reducing the impact on the stability of the connection between the red and blue light-emitting components and the flexible circuit board. Furthermore, each horizontal and vertical light-emitting group of the red and blue light-emitting components is covered with a light-transmitting cover. This serves two purposes: firstly, it protects the horizontal and vertical light-emitting groups from impacts by external objects; secondly, the light-transmitting cover further restrains the deformation of the flexible circuit board, particularly in the areas where the horizontal and vertical light-emitting groups are located, further ensuring the stability of the connection between the flexible circuit board and the red and blue light-emitting components, and ensuring the lifespan of the lamp board structure. It should be emphasized that, since the horizontal light-emitting group extends along the first direction, and at least one horizontal light-emitting group is provided along the second direction, and the horizontal light-emitting group is covered by the light-transmitting cover, the mechanical deformation of the lamp board structure along the first direction can be limited. Furthermore, since the horizontal light-emitting group is provided with vertical light-emitting groups at both ends of the first direction, and the vertical light-emitting groups extend along the second direction, and the vertical light-emitting groups are covered by the light-transmitting cover, the mechanical deformation of the lamp board structure along the second direction can be limited. Therefore, through the layout and arrangement of the horizontal light-emitting group, the vertical light-emitting group, and the light-transmitting cover, the deformation resistance of the area of ​​the flexible circuit board where the red and blue light-emitting components are provided can be enhanced, ensuring the connection stability between the red and blue light-emitting components and the flexible circuit board, and ensuring the service life of the lamp board structure.

Detailed Implementation

[0037] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0038] In the description of this invention, it should be understood that the term "comprising" as used in this specification means the presence of the stated features, integers, steps, operations, parts, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, parts, components, and / or groups thereof. It should be understood that when we say a part is "connected" to another part, it can be directly connected to the other part, or there may be intermediate parts. The term "and / or" as used herein includes all or any unit and all combinations of one or more associated listed items.

[0039] With the fast pace of modern life, prolonged desk work, sitting for long periods, or improper posture have led to a year-on-year increase in the incidence of lower back discomfort. Traditional physical therapies include massage, heat therapy, and traction, but these methods suffer from drawbacks such as reliance on manual operation, poor controllability, and lack of portability. However, with the development of wearable medical devices and smart physiotherapy equipment, red and blue light therapy is gradually being widely adopted due to its non-contact nature, lack of side effects, and significant efficacy. While some phototherapy products are available on the market, they generally suffer from issues such as easily damaged flexible circuit boards and detached LED beads, affecting their lifespan and efficacy, and failing to adequately meet the needs of lower back physiotherapy.

[0040] Red and blue light therapy is a non-invasive, safe, and widely used light therapy technique in medical rehabilitation, home therapy, and beauty care. By irradiating specific areas of the body with light of specific wavelengths, it activates photoreceptors within cells, triggering a series of beneficial physiological responses that can relieve pain, improve microcirculation, and repair tissues.

[0041] The red and blue light therapy belt combines the synergistic effect of red light irradiation to provide precise light energy treatment for common problems in the lower back, such as muscle strain, chronic soreness, and lumbar fatigue. It is a model of the integration of modern physical therapy and wearable devices.

[0042] Red light, with a wavelength of 630nm to 660nm, possesses strong penetrability, reaching 3 to 5 millimeters into the skin and acting on the dermis, subcutaneous capillaries, and superficial muscle tissue. After irradiation, red light is absorbed by cytochrome C oxidase in mitochondria, stimulating respiratory chain activity and increasing the efficiency of adenosine triphosphate (ATP) production, thereby enhancing cellular metabolism and promoting tissue repair. Furthermore, red light can dilate local capillaries, improve blood circulation, and enhance local oxygen supply and the efficiency of metabolic waste removal, thus providing some degree of analgesia and anti-inflammation.

[0043] Blue light, with wavelengths between 405nm and 470nm, has a shallow penetration depth, primarily affecting the skin's surface and superficial dermis. It possesses significant antibacterial and anti-inflammatory properties, particularly exhibiting photosensitivity to endogenous porphyrins produced during bacterial metabolism. Blue light irradiation can stimulate porphyrins to generate reactive oxygen species (ROS), thereby disrupting bacterial cell structure and achieving non-pharmacological photo-sterilization. Furthermore, blue light has a regulatory effect on the sympathetic nervous system, providing a calming and muscle-relaxing effect, which can help alleviate neurogenic lower back discomfort.

[0044] The combined irradiation of red and blue light creates a multi-layered biological treatment mechanism. Red light acts on deep tissues, promoting tissue repair and blood circulation, while blue light acts on the surface of the skin, achieving antibacterial and anti-inflammatory effects. Through the synergistic effect of different wavelengths in different spatial layers, a composite treatment pathway can be formed for problems such as lumbar muscle strain, chronic inflammation, and neurogenic pain, thereby improving the efficiency of physical therapy and the user experience.

[0045] Red light targets deep tissues, while blue light targets superficial tissues, working synergistically to achieve a combined treatment pathway. The greatest advantage of synergistic red and blue light irradiation lies in its ability to intervene at all levels, from the skin surface and dermis to superficial muscles, through layered tissue action. Blue light first rapidly "clears" the localized infected or inflamed areas, reducing interference from inflammatory bacteria and mediators; subsequently, red light deeply stimulates microcirculation and initiates repair mechanisms, thus achieving a complete "clearance + repair" chain treatment. Furthermore, the calming effect of blue light helps alleviate the slight heat or burning sensation that may occur during the initial stages of red light irradiation, improving treatment acceptance and tolerance. This synergistic mechanism possesses a complete process of "pretreatment—interventional treatment—continuous recovery," which is unattainable with traditional physiotherapy methods.

[0046] This invention is widely applicable to home rehabilitation, hospital-assisted treatment, office workers who sit for long periods, recovery from exercise fatigue, and postoperative rehabilitation care. It is particularly suitable for those suffering from chronic lumbar muscle strain, postoperative recovery from lumbar disc herniation, neuropathic pain caused by prolonged sitting, and circulatory disorders caused by coldness in the lower back. Through short-duration, high-frequency, targeted irradiation, it can effectively improve rehabilitation efficiency and reduce patients' dependence on pain medication.

[0047] like Figures 1 to 9 As shown, the present invention relates to a lamp panel structure having a first direction and a second direction that intersect perpendicularly, including a flexible circuit board 1, a support plate 2, a light-transmitting cover 3, and red and blue light-emitting components 4. The flexible circuit board 1 is attached to one side of the support plate 2, and at least two of the red and blue light-emitting components 4 are spaced apart along the first direction on the flexible circuit board 1.

[0048] The red and blue light-emitting component 4 includes a horizontal light-emitting group 41 and a vertical light-emitting group 42. At least one horizontal light-emitting group 41 is provided along the second direction, and the horizontal light-emitting group 41 extends along the first direction. Vertical light-emitting groups 42 are spaced apart at both ends of the horizontal light-emitting group 41 in the first direction. The vertical light-emitting groups 42 extend along the second direction. The flexible circuit board 1 has multiple welding areas, and each welding area is welded with one horizontal light-emitting group 41 or one vertical light-emitting group 42. The flexible circuit board 1 also has a light-transmitting cover 3, which covers each welding area. The light-transmitting cover 3 is used to restrict bending of the welding area of ​​the flexible circuit board 1, and there is a gap between adjacent light-transmitting covers 3. The first direction is the length direction of the support plate 2, and the second direction is the width direction of the support plate 2.

[0049] In existing physiotherapy belts, due to prolonged bending, twisting, or stretching during daily use, the flexible circuit board 1 is repeatedly subjected to mechanical deformation. Since neither the flexible circuit board 1 nor the LED beads are supported, the LED beads soldered to the flexible circuit board 1 are prone to detachment, affecting their lifespan. Therefore, in this invention, by attaching the flexible circuit board 1 to the support plate 2, a supporting function is provided for the flexible circuit board 1, thereby restraining its bending, twisting, and stretching, preventing excessive mechanical deformation, and reducing the impact on the stability of the connection between the red and blue light-emitting components 4 and the flexible circuit board 1. Furthermore, each of the welding areas is covered by a light-transmitting cover 3. That is, each of the horizontal light-emitting groups 41 and the vertical light-emitting groups 42 of the red and blue light-emitting components 4 is covered by the light-transmitting cover 3. This serves two purposes: firstly, it protects each of the horizontal light-emitting groups 41 and the vertical light-emitting groups 42 from being bumped by external objects; secondly, the light-transmitting cover 3 further constrains the deformation of the flexible circuit board 1, especially the welding areas of the flexible circuit board 1 where the horizontal light-emitting groups 41 and the vertical light-emitting groups 42 are located. This further ensures the stability of the welding between the flexible circuit board 1 and the red and blue light-emitting components 4, and ensures the service life of the lamp board structure. It should be emphasized that, since the horizontal light-emitting group 41 extends along the first direction, and at least one horizontal light-emitting group 41 is provided along the second direction, and the horizontal light-emitting group 41 is covered by the light-transmitting cover 3, the mechanical deformation of the lamp panel structure along the first direction can be limited. Furthermore, since the horizontal light-emitting group 41 is provided with vertical light-emitting groups 42 at both ends in the first direction, and the vertical light-emitting groups 42 extend along the second direction, and the vertical light-emitting groups 42 are covered by the light-transmitting cover 3, the mechanical deformation of the lamp panel structure along the second direction can be limited. Therefore, through the layout and arrangement of the horizontal light-emitting group 41, the vertical light-emitting group 42, and the light-transmitting cover 3, the deformation resistance of the area of ​​the flexible circuit board 1 where the red and blue light-emitting components 4 are provided can be enhanced, ensuring the connection stability between the red and blue light-emitting components 4 and the flexible circuit board 1, and ensuring the service life of the lamp panel structure.

[0050] In some embodiments, the support plate 2 has a groove 21 on at least one side in the second direction, and the groove 21 corresponds to the area between two adjacent red and blue light-emitting components 4.

[0051] In other words, by setting the groove 21, the structural strength of the support plate 2 can be weakened. Therefore, the area with the groove 21 makes the support plate 2 easier to bend, which is more convenient during use. Moreover, since the groove 21 corresponds to the area between two adjacent red and blue light-emitting components 4, bending in this area will not affect the connection between the flexible circuit board 1 and the red and blue light-emitting components 4.

[0052] Preferably, the groove 21 is an arc-shaped groove, and the arc-shaped groove transitions smoothly with the side surface of the support plate 2 in the second direction. This reduces stress concentration and prevents the support plate 2 from tearing at the location of the groove 21 even after repeated bending over a long period, thus improving its service life.

[0053] Furthermore, the support plate 2 is provided with grooves 21 on both sides in the second direction. The groove 21 on one side of the support plate 2 in the second direction corresponds one-to-one with the groove 21 on the other side of the support plate 2 in the second direction. The distance between the bottoms of the two opposite grooves 21 in the second direction is A, in mm. The distance between the two sides of the support plate 2 in the second direction is B, in mm. Wherein, 1 / 3≤A / B≤3 / 4.

[0054] That is, by providing the grooves 21 on both sides of the support plate 2 in the second direction, and the groove 21 on one side of the support plate 2 in the second direction corresponds one-to-one with the groove 21 on the other side of the support plate 2 in the second direction, the lamp board structure can be bent more easily for convenient use. At the same time, the area between the two grooves 21 does not contain the red and blue light-emitting components 4, so bending will not affect the connection between the red and blue light-emitting components 4 and the flexible circuit board 1.

[0055] Furthermore, the depth of the groove 21 is kept at 1 / 3 ≤ A / B ≤ 3 / 4, that is, the depth of the groove 21 is not too large to ensure the structural strength of the support plate 2 and prevent it from breaking easily after repeated bending. At the same time, the depth of the groove 21 is not too small so that the support plate 2 can be easily bent, making it easy for the lamp panel structure to be attached to the user's waist for convenient use.

[0056] In some embodiments, three horizontal light-emitting groups 41 are spaced apart along the second direction, and the two outermost horizontal light-emitting groups 41 located in the second direction are spaced apart from each other on both sides, corresponding to the two ends of the vertical light-emitting group 42 in the second direction.

[0057] That is, the two ends of the vertical light-emitting group 42 in the second direction will not extend beyond the two outermost horizontal light-emitting groups 41 in the second direction, so that the vertical light-emitting group 42 and the support plate 2 have sufficient distance in the second direction, so as not to affect the opening of the groove 21. At the same time, the distance between the two red and blue light-emitting components 4 in the first direction will not be too large, so as to maintain the compactness of the red and blue light-emitting components 4 on the lamp board structure.

[0058] In some embodiments, the light-transmitting cover 3 includes a cover body 31 and a connecting plate 32. The outer periphery of the cover body 31 extends outward to form the connecting plate 32, and the cover body 31 protrudes from the side of the connecting plate 32 away from the support plate 2. The connecting plate 32 is attached to the side of the flexible circuit board 1 away from the support plate 2. The cover body 31 is used to cover the horizontal light-emitting group 41 or the vertical light-emitting group 42.

[0059] The light-transmitting cover 3 includes a cover body 31 and a connecting plate 32. The connecting plate 32 is attached to the flexible circuit board 1, which increases the connection area between the light-transmitting cover 3 and the flexible circuit board 1, thereby strengthening the stability of the light-transmitting cover 3 on the flexible circuit board 1. At the same time, the cover body 31 protrudes from the side of the connecting plate 32 away from the support plate 2 to form a step, which can enhance the structural strength of the light-transmitting cover 3, making it more resistant to bending, and thus providing better protection for the horizontal light-emitting group 41 and the vertical light-emitting group 42.

[0060] Preferably, the lamp panel structure further includes a buffer pad 5, which is attached to the side of the flexible circuit board 1 away from the support plate 2, and the buffer pad 5 has clearance openings corresponding to the positions of the horizontal light-emitting group 41 and the vertical light-emitting group 42.

[0061] The buffer pad 5 can also cushion the entire lamp panel structure and improve the user's comfort when wearing it.

[0062] Furthermore, the side of the buffer pad 5 away from the support plate 2 is flush with the side of the connecting plate 32 away from the support plate 2, thereby increasing the flatness of the lamp panel structure on the side closest to the user when worn, thus improving the comfort after wearing.

[0063] Specifically, the buffer pad 5 is a rubber pad, a silicone pad, or a sponge pad.

[0064] In some embodiments, both ends of the light-transmitting cover 3 are arc-shaped along its length. This eliminates the sharp corners of the light-transmitting cover 3, preventing damage to the flexible circuit board 1 when the lamp panel structure is bent, and also improving the comfort of using the lamp panel structure.

[0065] In some embodiments, the lamp panel structure further includes a transparent sealing sleeve 6 and a power connection line 7. The flexible circuit board 1 and the support plate 2 are both located inside the transparent sealing sleeve 6. One end of the power connection line 7 enters the transparent sealing sleeve 6 and is electrically connected to the flexible circuit board 1. The other end of the power connection line 7 extends out of the transparent sealing sleeve 6.

[0066] That is, the support plate 2, the flexible circuit board 1, the light-transmitting cover 3, and the red and blue light-emitting components 4 are all housed within the transparent sealing sleeve 6 to protect the flexible circuit board 1 and prevent sweat from seeping onto the flexible circuit board 1 and the red and blue light-emitting components 4 during use, thus extending the lifespan of the lamp board structure. Then, one end of the power connection cable 7 enters the transparent sealing sleeve 6 and is electrically connected to the flexible circuit board 1, while the other end of the power connection cable 7 extends outside the transparent sealing sleeve 6 to smoothly supply power to the flexible circuit board 1.

[0067] In some embodiments, the transparent sealing sleeve 6 is made of PVC material.

[0068] The transparent sealing sleeve 6, made of PVC material, possesses transparency, sealing properties, and flexibility, thus not affecting the light transmission of the red and blue light-emitting components 4. Furthermore, PVC itself has good water resistance and chemical resistance, effectively preventing moisture and dust from entering, thereby improving the sealing effect and ensuring protection for the flexible circuit board 1 and the red and blue light-emitting components 4. Moreover, it allows the transparent sealing sleeve 6 to fit tightly against the flexible circuit board 1, the support plate 2, and the red and blue light-emitting components 4, enhancing assembly sealing performance.

[0069] In some embodiments, the support plate 2 is made of PC material.

[0070] The support plate 2, made of PC material, has high structural strength, enabling it to withstand greater external forces or compression without easily breaking, thus improving the overall stability and durability of the structure. Furthermore, the support plate 2 has excellent high-temperature resistance, ensuring it does not deform or degrade during long-term operation. Additionally, the support plate 2 exhibits strong flame retardancy and electrical insulation properties, providing fire protection and insulation protection, thus guaranteeing the lifespan of the lamp panel structure.

[0071] In some embodiments, the light-transmitting cover 3 is made of PVC material. The light-transmitting cover 3 is made of rigid PVC (Shore D50-80), which has a strong structure, does not block the passage of light sources, and is easy to manufacture and has a lower cost.

[0072] In some embodiments, both the horizontal light-emitting group 41 and the vertical light-emitting group 42 include a plurality of red and blue LED beads 43, which are soldered onto the flexible circuit board 1 to emit red and blue light to achieve a therapeutic effect.

[0073] Combination Figure 4 and Figure 5 As shown, in some embodiments, a graphite heat-conducting sheet 9 is provided between the support plate 2 and the flexible circuit board 1. The thickness of the graphite heat-conducting sheet 9 is 20-100μm, which can help the flexible circuit board 1 conduct heat evenly and prevent local overheating.

[0074] Specifically, since the horizontal light-emitting group 41 and the vertical light-emitting group 42 on the flexible circuit board 1 of this application are modularly connected on the flexible circuit board 1, the temperature of the area on the flexible circuit board 1 where the horizontal light-emitting group 41 and the vertical light-emitting group 42 are located will be relatively high during use. Therefore, the graphite heat-conducting sheet 9 can help the flexible circuit board 1 to conduct heat evenly and prevent local overheating. At the same time, the graphite heat-conducting sheet 9 is flexible so that it is not affected when the lamp board structure is bent.

[0075] In some embodiments, thermally conductive silicone can also be provided between the support plate 2 and the flexible circuit board 1 to provide both thermal conductivity and a certain buffering effect.

[0076] Combination Figure 7 As shown, in some embodiments, the support plate 2 has a deformation groove 22 on the side opposite to the flexible circuit board 1. The deformation groove 22 extends along the second direction, and the two ends of the deformation groove 22 extend to the two sides of the support plate 2 in the second direction.

[0077] That is, by opening a deformation groove 22 on the side of the support plate 2 facing away from the flexible circuit board 1, and extending the deformation groove 22 along the second direction, the support plate 2 can be bent to a certain extent along the first direction for easier use. At the same time, it does not affect the support of the support plate 2 on the flexible circuit board 1. In addition, since the deformation groove 22 is set on the side of the support plate 2 facing away from the flexible circuit board 1, it does not affect the flatness of the side of the support plate 2 close to the flexible circuit board 1, so the flexible circuit board 1 can be more stable when it is attached to the support plate 2.

[0078] Specifically, the support plate 2 has a deformation groove 22 on the side facing away from the flexible circuit board 1 and corresponding to the area of ​​the red and blue light-emitting component 4. That is, since the support plate 2 has grooves 21 on both sides in the second direction, if the deformation groove 22 is located in the corresponding area of ​​the groove 21, it will have a significant impact on the structural strength of the support plate 2 in the area where the groove 21 is provided. Therefore, by setting the deformation groove 22 on the side of the support plate 2 facing away from the flexible circuit board 1 and corresponding to the area of ​​the red and blue light-emitting component 4, it is possible to facilitate the bending of the lamp board structure and ensure that the support plate 2 can stably support the flexible circuit board 1.

[0079] Furthermore, the support plate 2 has a deformation groove 22 on the side facing away from the flexible circuit board 1 and in the area between the horizontal light-emitting group 41 and the vertical light-emitting group 42. That is, the deformation groove 22 further avoids the positions of the horizontal light-emitting group 41 and the vertical light-emitting group 42, so that the support plate 2 can be easily bent in the first direction without affecting the connection stability of the horizontal light-emitting group 41 and the vertical light-emitting group 42 with the flexible circuit board 1, making it easier for the lamp board structure to fit better against the user's waist.

[0080] In addition, the thickness of the support plate 2 is T, in mm, and the depth of the deformation groove 22 is H, in mm, wherein T≥2H.

[0081] That is, T≥2H is set to prevent the depth of the deformation groove 22 from having a significant impact on the structural strength of the support plate 2, thereby ensuring the structural strength of the lamp panel structure and its service life.

[0082] In the lamp panel structure of this invention, the horizontal light-emitting group 41 and the vertical light-emitting group 42 are arranged alternately, which not only improves the uniformity of illumination but also significantly reduces "treatment blind spots" caused by body movement. In actual use, the waist may experience wrinkles or tension changes due to different body positions (such as standing, sitting, and bending over), which may result in insufficient illumination in some areas. The alternate arrangement structure ensures that the light source can cover key areas under any deformation state. In addition, this structure reinforces the welding points with a light-transmitting cover, reducing circuit fatigue and solder joint breakage caused by bending and stretching during use, effectively improving the reliability and long-lasting therapeutic effect of the product.

[0083] The present invention also relates to a physiotherapy waist belt, including a connecting strap 8 and the lamp panel structure. The connecting strap 8 includes a main body 81 and a connecting part 82. The main body 81 has the connecting part 82 at both ends along the first direction. One end of each of the two connecting parts 82 is connected to the main body 81, and the other ends of the two connecting parts 82 are detachably connected together. The main body 81 has a placement space inside. The side of the main body 81 that is attached to the user's body has a light-transmitting element 83. The lamp panel structure is located in the placement space, and the red and blue light-emitting components 4 of the lamp panel structure face the light-transmitting element 83.

[0084] When the physiotherapy waist belt of the present invention is used, the main body 81 is attached to the user's waist, and then the connecting parts 82 located at both ends of the main body 81 are wrapped around the user's waist. The two ends of the two connecting parts 82 away from the main body 81 can be connected together, thereby wrapping the physiotherapy waist belt around the user's waist. The lamp panel structure is provided in the placement space, and the main body 81 is provided with a light-transmitting element 83 on one side of the user's body. Then the light emitted by the lamp panel structure can pass through the light-transmitting element 83 and shine on the user's body to achieve a physiotherapy effect.

[0085] In some embodiments, the light-transmitting element 83 is a transparent mesh PVC sheet, which provides good light transmittance and good mechanical strength and tear resistance, ensuring structural stability even after repeated bending of the therapeutic waist belt over a long period. Simultaneously, the light-transmitting element 83 also provides a seal to prevent sweat from seeping into the lamp panel structure during use.

[0086] In some embodiments, the main body 81 is further provided with an opening 84, and a zipper 85 is provided at the opening 84 for opening or closing the opening 84 by means of the zipper 85.

[0087] That is, the opening 84 on the main body 81 can be opened by the zipper 85 to place the lamp panel structure in the placement space, and the opening 84 can also be closed by the zipper 85 to secure the lamp panel structure in the placement space of the main body 81. Therefore, it is convenient to assemble and disassemble the lamp panel structure.

[0088] In some embodiments, the two ends of the two connecting portions 82 away from the main body portion 81 are connected together by Velcro 86 for user convenience.

[0089] In some embodiments, the connecting portion 82 is an elastic band to improve the applicability and practicality of the physiotherapy belt.

[0090] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
