Technical Field

[0001] This utility model relates to the field of phototherapy technology, and in particular to an LED phototherapy device. Background Technology

[0002] In the modern beauty industry, LED light therapy pads have become a very popular physiotherapy and beauty tool. These pads use LED light sources to emit light of specific wavelengths, which, through photobiological effects, can improve skin, relieve pain, promote wound healing, and promote hair growth.

[0003] For example, the US Patent No. 11109458B2, which is a patent in the existing patent literature, discloses a "Phototherapy system with dynamic drive for light-emitting diodes". Paragraphs 0205 to 0218 of the specification of this patent describe in detail the principle and application of phototherapy using specific light waves.

[0004] However, existing phototherapy pads have some shortcomings. First, they easily attract dust and are not resistant to dirt. During use, the surface of the pad will accumulate a large amount of dust, which not only affects its appearance but may also affect the output of the light source, thus reducing the therapeutic effect. Second, existing phototherapy pads have poor waterproof capabilities. If the therapy device comes into contact with moisture, it may cause a short circuit or even lead to electric shock. Furthermore, storing them in a humid environment may cause the circuit board to oxidize, affecting the product's lifespan.

[0005] Based on this, the present invention proposes an LED phototherapy device to solve the aforementioned technical problems. Utility Model Content

Therefore, the use of terms not limited to those described in the specification may be appropriately replaced as needed.

[0027] This utility model discloses an LED phototherapy device, such as Figure 1 As shown, it includes a main body 100, which includes a base layer 1000, a transparent layer 2000, and an LED light strip layer 3000 disposed between the base layer 1000 and the transparent layer 2000.

[0028] In this embodiment, as Figure 2 As shown, the base layer 1000 includes at least one first length side 1001 and at least one first width side 1002, the first length side 1001 and the first width side 1002 defining a first adhesive surface 1003 of the base layer 1000. The transparent layer 2000 includes at least one second length side 2001 and at least one second width side 2002, the second length side 2001 and the second width side 2002 defining a second adhesive surface 2003 of the transparent layer 2000, as... Figure 11 , Figure 12 As shown, the second adhesive surface 2003 is also provided with a focusing bump 2005, which is used to focus the light emitted by the LED strip layer 3000, so that the light emitted by the LED is more uniform and more concentrated.

[0029] These focusing bumps 2005 act like convex lenses, capturing light from the LED strip layer 3000 and directing it in a more concentrated direction through refraction and focusing. This process not only significantly improves light utilization and reduces light scattering and waste, but also ensures more uniform light intensity in the illuminated area, avoiding uneven brightness. By optimizing light distribution and enhancing light concentration, they achieve a more efficient and uniform lighting effect.

[0030] In this embodiment, the LED light strip layer 3000 includes an upper surface 3001 and a lower surface 3002. The lower surface 3002 is bonded to the first adhesive surface 1003 through a first adhesive layer 1004, and the upper surface 3001 is bonded to the second adhesive surface 2003 through a second adhesive layer 2004. The bonded base layer 1000, transparent layer 2000, and LED light strip layer 3000 are pressed together to form the main body 100. The LED light strip layer 3000 is located at the center of the base layer 1000, which allows the light from the LED light strip layer 3000 to be evenly distributed on the main body 100, thereby providing a more effective therapeutic effect. The transparent layer 2000 can effectively transmit the light emitted by the LED light strip layer 3000, making the light more uniform and improving the phototherapy effect of the main body 100. In addition, the main body 100 has a three-layer structure, which gives it strong stability and durability.

[0031] Light from light-emitting diodes (LEDs) can stimulate the metabolism of mitochondria in cells, especially when LED light stimulates photosensitive chemicals (such as chromophores and the cytochrome system). Further research shows that the light energy of cold-light LEDs can stimulate the activity of fibroblasts, thereby promoting the production of collagen and elastin cells, reducing dry and itchy skin, eliminating acne, and improving repair capabilities. The application of LEDs in phototherapy, beauty treatments, and body shaping primarily uses visible and near-infrared light of suitable wavelengths to act on abnormal cells on the skin surface and subcutaneous tissue, stimulating singlet oxygen. This singlet oxygen has a strong killing effect on abnormal cells and simultaneously lowers the pH gradient around the cells. In this environment, abnormal cells lose their vitality and are absorbed by surrounding normal cells and tissues, thus achieving the treatment of various skin diseases such as acne, eczema, and dermatitis. On the other hand, suitable soft LED light can promote the production of subcutaneous collagen and promote the decomposition and fading of subcutaneous pigmentation, thus achieving effects such as eliminating facial wrinkles, age spots, and skin rejuvenation and whitening.

[0032] In this embodiment, as Figure 3 As shown, the main body 100 also includes a power connection line 200, which is electrically connected to an external power supply or control board to power the LED light strip layer 3000 so that the main body 100 can work and provide physiotherapy services for the user.

[0033] In silicone pad production, silicone lamination is a method of manufacturing silicone products. Cut silicone material is placed into a high-temperature mold, and pressure is applied by a vulcanizing machine to vulcanize it into a solid at high temperature. At high temperature, the silicone material reacts with the vulcanizing agent to form vulcanized silicone. The vulcanized silicone product is then cooled to harden and maintain its shape.

[0034] In this embodiment, the bonded base layer 1000, transparent layer 2000, and LED strip layer 3000 are pressed together to form the main body 100. Through the pressing process, the base layer 1000, transparent layer 2000, and LED strip layer 3000 are tightly bonded together to form a whole. This can improve the stability and durability of the product. The transparent layer 2000 and base layer 1000 can effectively protect the LED strip layer 3000 from mechanical impact or environmental factors, thereby extending the service life of the LED strip. In addition, by pressing the base layer 1000, transparent layer 2000, and LED strip layer 3000 together, the entire main body 100 becomes more concise and aesthetically pleasing.

[0035] In other embodiments (not shown in the figures), the base layer 1000, transparent layer 2000, and LED strip layer 3000 can be bonded using a compression molding method. Compression molding involves placing solid silicone raw material with added vulcanizing agent into a high-temperature mold and applying pressure through a vulcanizing machine to bond them together. Compression molding can produce products with complex shapes and fine details. In other embodiments (not shown in the figures), the base layer 1000, transparent layer 2000, and LED strip layer 3000 can also be bonded using a casting mold method. Casting mold molding can produce products with smooth surfaces and simple shapes, and it has high production efficiency.

[0036] In other embodiments (not shown in the figure), a protective film can also be provided on the side of the substrate 1000 facing away from the LED strip layer 3000. Preferably, the protective film is a polycarbonate film, and the polycarbonate film is applied to the substrate 1000 by a pressing process. By providing a protective film, the substrate 1000 can be protected, providing waterproofing, stain resistance, and wear resistance, thus extending the service life of the substrate 1000. It also increases the toughness of the substrate 1000, allowing it to maintain its shape and spring back to a normal plane.

[0037] The side of the substrate layer 1000 facing the LED strip layer 3000 can also be processed using a dripping process. This dripping process makes the substrate layer 1000 thinner overall, maintaining its shape and providing better resilience.

[0038] By laminating a protective film onto the back of the substrate 1000 and performing an adhesive dispensing process on the front of the substrate 1000, a multi-layer structure can be formed in the substrate 1000. This improves the flexibility and elasticity of the substrate 1000, increases its lifespan, and consequently extends the lifespan of the phototherapy device.

[0039] In this embodiment, as Figure 4As shown, a protective layer 1005 is also provided on the outer surface of the main body 100. The protective layer 1005 is formed by spraying a tactile oil onto the main body 100. The tactile oil can make the surface of the main body 100 smoother and more comfortable to touch, thus improving the user experience. Since silicone is a highly absorbent material, it easily absorbs dust from the air. After spraying the tactile oil, a protective film can be formed to reduce static electricity, thereby reducing dust adsorption. At the same time, it can also prevent water from entering the LED light strip layer 3000 and causing circuit damage. The tactile oil also has a certain degree of wear resistance, which can improve the service life of the main body 100. In addition, the tactile oil can also improve the appearance and texture of the main body, making the product look more beautiful.

[0040] In this embodiment, both the base layer 1000 and the transparent layer 2000 are made of silicone material. The base layer 1000 helps dissipate heat from the LED strip layer 3000, preventing it from overheating and thus improving its stability and lifespan. The transparent layer 2000 transmits the light emitted by the LED strip layer 3000 without causing excessive light loss, ensuring the brightness and color of the LED strip layer 3000 are well maintained. Silicone has excellent high-temperature resistance and will not deform or be damaged due to high temperatures even under prolonged illumination and heat generation. Silicone also has good electrical insulation properties, preventing current leakage or short circuits. Furthermore, silicone is a soft and elastic material, allowing the body 100 to be adjusted to fit the user's body shape, providing excellent comfort.

[0041] In other embodiments (not shown in the figures), the base layer 1000 can be made of engineering plastics such as polycarbonate or polyoxymethylene, which has good mechanical properties and heat resistance. The transparent layer 2000 is made of transparent plastics such as polymethyl methacrylate or polycarbonate, which has good light transmittance and impact resistance. The LED strip layer 3000 can be made of high-performance plastics such as polyimide or polyetheretherketone, which has excellent electrical insulation and heat resistance.

[0042] In this embodiment, as Figure 5As shown, the base layer 1000, the transparent layer 2000, and the LED strip layer 3000 all have a cuboid structure. The length L1 and width H1 of the base layer 1000 are the same as the length L2 and width H2 of the transparent layer 2000. The length L3 and width H3 of the LED strip layer 3000 are smaller than the length L2 and width H2 of the transparent layer 2000. Since the length L3 and width H3 of the LED strip layer 3000 are smaller than the L2 and width H2 of the transparent layer 2000, this means that the LED strip layer 3000 is completely covered by the transparent layer 2000. When the LED 3007 emits light, the light will be evenly dispersed through the transparent layer 2000, thereby achieving a uniform light distribution.

[0043] In this embodiment, as Figure 6 As shown, the thickness T1 of the substrate layer 1000 is not less than the thickness T2 of the transparent layer 2000, and the thickness T3 of the LED strip layer 3000 is less than the thickness T2 of the transparent layer 2000. The substrate layer 1000 provides good support for the LED strip layer 3000 and protects it from the influence of the external environment. Since the thickness of the LED strip layer 3000 is less than the thickness of the transparent layer 2000, there is a certain space between the LED strip layer 3000 and the transparent layer 2000. This space can serve as a heat dissipation channel to help the LED 3007 dissipate heat, thereby improving the service life of the LED 3007.

[0044] In other embodiments (not shown in the figures), the substrate layer 1000, the transparent layer 2000, and the LED strip layer 3000 all have cylindrical structures. Because these structures are cylindrical, the light emitted by the LED 3007 can be evenly dispersed within a 360° range, thus achieving uniform light distribution. In other embodiments (not shown in the figures), the substrate layer 1000, the transparent layer 2000, and the LED strip layer 3000 can also have square, circular, or irregular shapes.

[0045] In other embodiments (not shown in the figures), the substrate layer 1000, the transparent layer 2000, and the LED strip layer 3000 have the same length, width, and thickness, making the overall product design simpler and more unified, and also making the production and assembly process simpler and more efficient.

[0046] In this embodiment, as Figure 7As shown, the LED light strip layer 3000 includes an upper end 3003 and a lower end 3004. Multiple LED light strips 3005 are located between the upper end 3003 and the lower end 3004. Specifically, there are seven LED light strips 3005 between the upper end 3003 and the lower end 3004. A gap 3006 is provided between adjacent LED light strips 3005. The lateral width of the gap 3006 is smaller than the lateral width of the LED light strip 3005. The gap 3006 between adjacent LED light strips 3005 helps dissipate heat, prevents overheating of the LED light strips 3005, and thus extends the product's lifespan.

[0047] In other embodiments (not shown in the figures), the LED light strip 3005 can be configured with eight strips or any other desired number, thereby providing a larger radiation area and making the light more uniform.

[0048] In this embodiment, the LED light strip 3005 is configured as a flexible light strip, which has good flexibility and can be freely bent, rolled or folded. It can be adjusted into any shape according to spatial layout requirements to meet different user needs and improve the user experience. In other embodiments (not shown in the figure), the LED light board 3005 can also be configured as a rigid light board, which facilitates subsequent fixing, processing and installation.

[0049] In other embodiments (not shown in the figures), the lateral width of the gap 3006 between adjacent LED light strips 3005 is the same as the lateral width of the LED light strip 3005, which can make the light more uniform and avoid glare caused by excessive light concentration. The fact that the lateral width of the gap 3006 is the same as the lateral width of the LED light strip 3005 can make the product more beautiful and improve the overall visual effect.

[0050] In other embodiments (not shown in the figures), the LED strip layer 3000 can be configured to have continuous LED strips 3005, wherein the LED strips 3005 are closely connected without gaps, thereby providing better structural integrity and stability, and providing better current continuity, effectively avoiding current interruption during use.

[0051] In this embodiment, the width A1 of the upper end 3003 is greater than the width A2 of the lower end 3004, thereby providing a larger area for the display lamp 3008 and making the whole product more aesthetically pleasing.

[0052] In other embodiments (not shown in the figures), the width of the upper end 3003 is the same as the width of the lower end 3004, thereby providing a position for mounting the indicator light 3006 at the lower end 3002, and also improving the overall aesthetics of the product.

[0053] In this embodiment, as Figure 8 As shown, each LED light strip 3005 also has several LED lights 3007 that correspond one-to-one with the focusing protrusions (2005). The LED lights 3007 are evenly distributed on the LED light strip 3005. Specifically, each LED light strip 3005 is equipped with 12 LED lights 3007. The evenly distributed LED lights 3007 can ensure the uniform distribution of light and provide a stable and consistent therapeutic effect.

[0054] In this embodiment, the upper end 3003 also includes two indicator lights 3008, which are arranged vertically and can provide the user with the working status information of the device.

[0055] In other embodiments (not shown in the figures), three indicator lights 3008 or any other desired number may be provided on the upper end 3003. By increasing the number of indicator lights 3008, richer operating status indications can be provided. In other embodiments (not shown in the figures), the indicator lights 3008 may also be arranged horizontally on the upper end 3003, which can provide more intuitive status indications and also improve the overall aesthetics of the product.

[0056] In another embodiment (not shown in the figure), the main body 100 adopts a design without display lights, thereby reducing product complexity, reducing energy consumption, and reducing costs.

[0057] In this embodiment, as Figure 9 As shown, a filling layer 3009 is provided between the LED light strip layer 3000 and the transparent layer 2000.

[0058] The size of the LED strip layer 3000 is smaller than that of the filler layer 3009. Therefore, the part of the bottom surface of the filler layer 3009 that is larger than the periphery of the LED strip layer 3000 and the gap between the LED strips 3005 are bonded to the base layer 1000.

[0059] The filling layer 3009 has several through holes 3010 corresponding to the LED lamp 3007, which allow the light emitted by the LED lamp 3007 to be transmitted directly through the through holes 3010, thereby reducing light loss during transmission and improving light efficiency. The filling layer 3009 can also serve as an effective heat dissipation layer to help the LED lamp 3007 dissipate heat, thereby improving the lifespan of the LED lamp 3007. In addition, the filling layer 3009 enhances the stability of the entire structure.

[0060] In this embodiment, as Figure 10As shown, the filling layer 3009 has a cuboid structure. The length L4, width H4, and thickness T4 of the filling layer 3009 are the same as the length L2, width H2, and thickness T2 of the transparent layer 2000. The presence of the filling layer 3009 can provide additional protection for the LED lamp 3007, preventing the LED lamp 3007 from being affected by the external environment. In addition, the filling layer 3009 can increase the heat dissipation surface area, which can help the LED lamp 3007 dissipate heat better, thereby improving the lifespan of the LED lamp 3007. Furthermore, the filling layer can be white, green, yellow, etc., and the design of different colors with the same appearance size can make the whole product more beautiful.

[0061] In other embodiments (not shown in the figures), the thickness T4 of the filler layer 3009 is greater than that of the transparent layer 2000 and the thickness T2. Increasing the thickness of the filler layer 3009 can provide stronger protection for the LED light strip layer 3000 and prevent the LED light strip layer 3000 from being affected by the external environment more severely.

[0062] In this embodiment, as Figure 11 As shown, the filler layer 3009 includes a first upper surface 3101 and a first lower surface 3102. The first lower surface 3102 is attached to the upper surface 3001 and bonded to the base layer 1000 through a third adhesive layer 3103. The first upper surface 3101 and the second adhesive surface 2003 are bonded to each other through a fourth adhesive layer 3104. The two surfaces of the filler layer 3009 are bonded to the base layer 1000 and the transparent layer 2000 respectively, providing a more stable structure and improving the durability of the product.

[0063] In this embodiment, the filler layer 3009 is made of silicone material. Silicone has good thermal conductivity, which can effectively conduct away the heat generated by the LED lamp 3007, thereby helping the LED lamp 3007 dissipate heat and improve its service life. In addition, silicone has excellent waterproof, dustproof, impact-resistant and anti-aging properties, which can effectively protect the LED lamp 3007 and enable it to work stably under various environmental conditions. Furthermore, silicone also has good light transmittance, which allows the light emitted by the LED lamp 3007 to be more evenly dispersed through the transparent layer 2000, thereby improving light efficiency.

[0064] In this embodiment, the first adhesive layer 1004, the second adhesive layer 2004, the third adhesive layer 3103 and the fourth adhesive layer 3104 are all made of adhesive, which is made of organic polymer compound.

[0065] In other embodiments (not shown in the figures), epoxy resin adhesive can be used as the adhesive used in the production process of this invention. Epoxy resin adhesive has low toxicity, low volatility, wide mixing ratio, simple operation, can be cured at room temperature, and has strong adhesion and good toughness, which can effectively save the loss of material and financial resources in the production process.

[0066] In other embodiments (not shown in the figures), polyurethane adhesive can be selected as the adhesive used in the production process of this invention. Polyurethane adhesive has excellent flexibility and weather resistance, and can maintain good bonding performance in various harsh environments. In addition, polyurethane adhesive also has good abrasion resistance and impact resistance.

[0067] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
