Description

Technical Field

[0001] This utility model relates to the field of light therapy technology, and in particular to a therapy lens and a therapy lamp. Background Technology

[0002] Physiotherapy lamps are lighting fixtures used in the fields of physiotherapy, health care, and beauty. These lamps emit light of different wavelengths, such as red light at 630nm and 660nm, and infrared light at 810nm and 850nm. Different wavelengths provide different amounts of light energy, thus achieving therapeutic effects. For example, the aforementioned 630nm and 660nm red light and 810nm and 850nm infrared light have high radiation frequencies and good penetrability. When irradiated on the human body, they can stimulate cell activity, promote cell repair, accelerate blood circulation, and improve metabolism, thereby achieving anti-inflammatory, antibacterial, and wound-healing therapeutic effects.

[0003] Physiotherapy lenses are used in physiotherapy lamps. Physiotherapy lenses can reshape the light emitted by the lamp beads in the physiotherapy lamps and then emit it, so that the light emitted by the lamp beads can be more concentrated on the target human body parts.

[0004] Therapeutic lamps commonly use LEDs (Light-emitting Diodes). Due to the design limitations of LEDs, a single LED typically has only one emission wavelength. Therefore, to emit light of different wavelengths, a therapeutic lamp needs to be equipped with a corresponding therapeutic lens for each LED. Multiple therapeutic lenses and their corresponding LEDs are arranged in an array to form a common light-emitting surface. Light emitted by LEDs with different emission wavelengths exits from this surface, thus illuminating the human body with light of different wavelengths.

[0005] However, in practice, it's sometimes unnecessary to emit all wavelengths of light. This is because different wavelengths of light have different therapeutic effects, and users may only need to achieve some of these effects, thus turning off the additional LEDs. In this case, the therapeutic lenses corresponding to the non-emitting LEDs will also not emit light, but they will still occupy part of the light-emitting surface, resulting in dark areas on the light-emitting surface (i.e., the areas occupied by the therapeutic lenses corresponding to the off LEDs). The appearance of these dark areas reduces the effective light-emitting area of ​​the light-emitting surface, thus reducing the overall illumination range of the therapeutic lamp and diminishing its therapeutic effect. Utility Model Content

[0006] The main purpose of this utility model is to provide a physiotherapy lens and a physiotherapy lamp, which aims to improve the physiotherapy effect of the physiotherapy lamp.

[0007] To achieve the above objectives, the present invention proposes a physiotherapy lens for use in a physiotherapy lamp. The physiotherapy lamp includes at least two LEDs, and the physiotherapy lens includes a substrate. At least two placement slots are provided on one side of the substrate. One of the placement slots is used to accommodate the light-emitting part of one LED. The substrate is made of a light-guiding material and is used to guide the light emitted by the LED from the placement slot along the tangential direction of the substrate.

[0008] In some embodiments, the physiotherapy lens further includes at least two lamp holders disposed on one side of the substrate and extending away from the substrate.

[0009] The placement groove is formed on the end of the lamp holder away from the substrate and is recessed towards the substrate;

[0010] The lamp holder is used to guide the emitted light from the lamp bead into the substrate and emit it from the side of the substrate facing away from the lamp holder.

[0011] In some embodiments, the outer side of the lamp holder facing away from the placement slot is a total reflection surface; the total reflection surface is used to totally reflect at least a portion of the emitted light from the lamp bead so that it can be incident on the substrate.

[0012] In some embodiments, the total reflection surface is configured such that the propagation direction of the reflected light from at least a portion of the total reflection surface is at an angle to the normal direction of the substrate.

[0013] In some embodiments, the bottom of the placement slot is an optical surface, which has positive or negative optical power; the optical surface is used to shape the emitted light of at least a portion of the lamp beads before it is incident on the substrate.

[0014] In some embodiments, the optical surface is configured such that at least a portion of the emitted light from the optical surface propagates at an angle to the normal direction of the substrate.

[0015] In some embodiments, the number of lamp holders disposed on one substrate is four; the four lamp holders on one substrate are arranged in a square array and are disposed adjacent to each other.

[0016] In some embodiments, a light-scattering portion is provided on the side of the substrate near the placement groove; the light-scattering portion is a protrusion protruding from the surface of the substrate and / or a groove recessed into the surface of the substrate; there are multiple light-scattering portions, and the multiple light-scattering portions are distributed in an array on the substrate; the light-scattering portion is used to scatter light propagating in the substrate and along the tangential direction of the substrate.

[0017] In some embodiments, the physiotherapy lens further includes a mounting post disposed on the side of the substrate near the placement groove and extending from the substrate in a direction away from the substrate; the mounting post is used to mount the physiotherapy lens on a preset mounting position on the physiotherapy lamp.

[0018] This utility model also proposes a physiotherapy lamp, including the aforementioned physiotherapy lens.

[0019] In this invention, because two placement slots are provided on the substrate, one substrate can correspond to two LED beads. These two LED beads can emit light of different wavelengths. Thus, when an LED bead emitting one wavelength is turned off, an LED bead emitting another wavelength is turned on (at least one wavelength LED bead is lit during use). This ensures that at least one LED bead corresponding to a therapeutic lens is always on. Furthermore, because the substrate allows the light emitted by the LED beads to propagate along the tangent of the substrate, the light gradually exits from various parts of the side of the substrate facing away from the placement slots, ensuring that light can be emitted from the entire side of the substrate facing away from the placement slots. When the therapeutic lenses are arranged in a row, even if only one wavelength LED bead is turned on, the light-emitting surfaces of all therapeutic lenses, i.e., the side of the substrate facing away from the placement slots, can emit light completely. There are no non-emitting therapeutic lenses, therefore there are no dark areas on the light-emitting surfaces of the therapeutic lens array, increasing the illumination range of the therapeutic lamp and thus improving its therapeutic effect.

[0042] This utility model proposes a physiotherapy lens.

[0043] Please see Figure 1 , Figure 2 and Figure 9 The therapeutic lens 10 proposed in this invention is applied to a therapeutic lamp 100, which includes at least two LED beads 102. The therapeutic lens 10 includes a substrate 11. At least two placement slots 121 are provided on one side of the substrate 11. One placement slot 121 is used to accommodate the light-emitting part 1021 of one LED bead 102. The substrate 11 is made of a light-guiding material and is used to conduct the light emitted by the LED bead 102 from the placement slot 121 along the tangential direction of the substrate 11.

[0044] like Figure 1As shown, a therapeutic lens 10 is disposed on the housing 101 of the therapeutic lamp 100. At least two LED beads 102 are disposed within the housing 101 of the therapeutic lamp 100. Each therapeutic lens 10 corresponds to at least two LED beads 102, and the two LED beads 102 can emit light of different wavelengths. Specifically, the number of LED beads 102 corresponding to one therapeutic lens 10 can be set according to the types of wavelengths required to be emitted by the therapeutic lamp 100. For example, if the therapeutic lamp 100 needs to emit approximately three different wavelengths of light, one therapeutic lens 10 can correspond to three LED beads 102, and the three LED beads 102 corresponding to one therapeutic lens 10 can respectively emit the three wavelengths of light required by the therapeutic lamp 100. Thus, whenever the therapeutic lamp 100 is in operation, at least one of the LED beads 102 corresponding to one therapeutic lens 10 is lit.

[0045] The aforementioned correspondence between the physiotherapy lens 10 and the LED beads 102 means that the placement slot 121 on one physiotherapy lens 10 is correspondingly set to one LED bead 102. For example, when the physiotherapy lens 10 is correspondingly set to four LED beads 102, then one physiotherapy lens 10 is provided with four placement slots 121, and the light-emitting parts 1021 of the four LED beads 102 are respectively placed in the four placement slots 121.

[0046] The light-emitting part 1021 of the lamp bead 102 refers to the part of the lamp bead 102 used to emit light. The placement groove 121 accommodates the light-emitting part 1021 of the lamp bead 102, so that the light emitted by the lamp bead 102 can be basically projected onto the groove wall of the placement groove 121. Since the placement groove 121 is provided on the substrate 11, the light emitted by the lamp bead 102 can enter the substrate 11 through the groove wall of the placement groove 121.

[0047] The placement slot 121 can be directly formed on the substrate 11, or it can be... Figure 2 As shown, a lamp holder 12 is provided on the substrate 11 so as to be indirectly provided on the substrate 11.

[0048] The substrate 11 is basically plate-shaped. On the one hand, this allows the substrate 11 to have a certain degree of curvature (or it can be completely flat); on the other hand, it allows the substrate 11 to have other structures that do not disrupt the plate-shaped configuration, such as... Figure 3 In the illustrated embodiment, the substrate 11 is divided into two layers. The layer closer to the lamp holder 12 has a larger surface area than the layer farther from the lamp holder 12. This allows the larger layer of the substrate 11 to be easily pressed against the housing 101 of the physiotherapy lamp 100, while the smaller layer is exposed through holes in the housing 101 for light emission. Please refer to the reference. Figure 1 ,when Figure 3 The implementation methods in the document are applied to Figure 1 The therapeutic lamp shown is 100. Figure 1 The layer shown is the one with a smaller surface area of ​​substrate 11.

[0049] Of course, in different implementations, the physiotherapy lamp 100 may not have a housing 101, but may simply use a bracket structure to fix the lamp beads 102 and the physiotherapy lens 10.

[0050] The substrate 11 is made of a light-guiding material, meaning it is essentially transparent and has a different refractive index than the medium surrounding the therapeutic lens 10. Since the therapeutic lens 10 is typically placed in air, the refractive index of the substrate 11 differs from that of air. The substrate 11 is essentially transparent; it can be completely transparent or have a certain color to optimize for different wavelengths of the LED beads 102. Common light-guiding materials include glass, optical resin, and transparent (or colored) plastics.

[0051] The principle of light transmission on substrate 11 can be found in [reference]. Figure 10 When light is incident on substrate 11, it can propagate in a zigzag pattern within substrate 11 (e.g., Figure 10 As shown in the light path in the substrate 11 on the right side, each time light comes into contact with the substrate 11, it is refracted and exits the substrate 11. However, the refractive index is not 100%, so the remaining light continues to propagate and is refracted again when it encounters the substrate 11 again. This forms light rays that continuously propagate in the tangential direction of the substrate 11 and gradually exit from the substrate 11, so that light is emitted from the entire exit surface of the physiotherapy lens 10. Therefore, as long as one lamp bead 102 is lit, the entire lens will emit light.

[0052] As can be seen, the physiotherapy lens 10 in the technical solution disclosed in this application allows light to be emitted from the entire emission surface (i.e., the emission surface formed by the collection of emission surfaces of all physiotherapy lenses 10) of the physiotherapy lamp 100 even when some wavelengths of the lamp beads 102 are turned off. There are no dark areas (i.e., the areas occupied by the physiotherapy lenses 10 that do not emit light) on the emission surface, which increases the illumination range of the physiotherapy lamp 100 and thus improves the physiotherapy effect of the physiotherapy lens 10.

[0053] Furthermore, from a visual perspective, users will intuitively notice that the therapeutic lamp 100 is always lit. According to the inventors' observations of users, the appearance of dark areas on the light-emitting surface of the therapeutic lamp 100 creates a negative psychological suggestion for the user, leading them to subjectively perceive a decrease in therapeutic efficacy (which is indeed the case). This psychological effect also reduces the therapeutic efficacy of the therapeutic lamp 100. Therefore, the therapeutic lamp provided in this application, by ensuring that the entire light-emitting surface of the therapeutic lamp 100 is always lit, can provide users with a positive psychological suggestion, further enhancing the therapeutic effect of the therapeutic lamp 100.

[0054] Since the light-emitting part 1021 of the lamp bead 102 is placed in the placement slot 121, it also has a fixing function for the lamp bead 102. At least two lamp beads 102 are accommodated in the placement slot 121 of the substrate 11. In this way, multiple lamp beads 102 can be fixed by installing one physiotherapy lens 10. This eliminates the need to set up a physiotherapy lens 10 for each lamp bead 102, thus saving the overall volume of multiple physiotherapy lenses 10 and multiple lamp beads 102 (the installation structure is more simplified and does not occupy too much space), which is conducive to the miniaturization of the physiotherapy lamp 100.

[0055] Please refer to Figure 2 and Figure 3 In some embodiments, the physiotherapy lens 10 further includes at least two lamp holders 12, which are disposed on one side of the substrate 11 and extend away from the substrate 11. A placement groove 121 is formed on the end of the lamp holder 12 away from the substrate 11 and is recessed towards the substrate 11. The lamp holder 12 is used to guide the emitted light from the lamp bead 102 into the substrate 11 and emit it from the side of the substrate 11 opposite to the lamp holder 12.

[0056] like Figure 10 As shown, it can be seen that for light propagating along the tangential direction of substrate 11 (for light directly transmitted through substrate 11, the following statement is not true; for light directly transmitted as...), Figure 9 The light shown, and Figure 10 (As shown in the left-hand side of the diagram), the thickness of substrate 11 affects the speed at which light diverges as it propagates within substrate 11. That is, the more times light is emitted to the emitting surface of substrate 11 per unit distance, the faster the light is emitted from substrate 11. Therefore, if rapid light emission from substrate 11 is required, the thickness of substrate 11 needs to be reduced; conversely, if slower light emission from substrate 11 is required, the thickness of substrate 11 needs to be increased.

[0057] Because of the lamp holder 12, the substrate 11 does not need to reserve thickness for opening the placement slot 121, so the thickness setting of the substrate 11 is more flexible and more conducive to optimizing the substrate 11.

[0058] like Figure 2 and Figure 3 In the embodiment shown, the lamp holder 12 is cup-shaped, but in other embodiments not shown, the lamp holder 12 may be column-shaped or other shapes.

[0059] The lamp holder 12 and the substrate 11 can be integrally molded, allowing them to be made of the same material. However, if a secondary injection molding process is used, even if the lamp holder 12 and the substrate 11 are integrally molded, they may not be made of the same material. The lamp holder 12 and the substrate 11 can also be connected by abutment alone or by optical adhesive.

[0060] Since the lamp holder 12 needs to conduct light, it can also be made of a light-guiding material. The lamp holder 12 also needs to be substantially transparent. In addition, the light guiding of the lamp holder 12 can rely on reflection (i.e., the embodiment with total reflection surface 122 described below), or it can rely on focusing light by optical surface 1211 (see below for details). Of course, the lamp holder 12 can also rely on both reflection and focusing by optical surface 1211, so that light can be conducted in the lamp holder 12.

[0061] Please refer to Figure 7 , Figure 8 and Figure 9 In some embodiments, the outer side of the lamp holder 12 facing away from the placement groove 121 is a total reflection surface 122; the total reflection surface 122 is used to total reflect at least part of the emitted light from the lamp bead 102 so that it can be incident on the substrate 11.

[0062] The formation of the total internal reflection surface 122 requires that the refractive index of the lamp holder 12 be greater than the refractive index of the surrounding medium when the therapeutic lens 10 is working. Since the therapeutic lens 10 typically operates in air, the refractive index of the lamp holder 12 only needs to be greater than 1. The lamp bead 102 can typically be an LED or similar lamp bead 102. Because the lamp bead 102 emits light divergingly, when at least a portion of the light is incident on the surface of the lamp holder 12, which is the total internal reflection surface 122, the angle of incidence can be greater than the critical angle for total internal reflection (i.e., the angle of incidence of total internal reflection). Figure 9 When the angle θ is greater than the critical angle, total internal reflection occurs, allowing the light emitted from the LED 102 to be focused and emitted in the direction of the substrate 11. For details, please refer to... Figure 9 The light path shown is designed to concentrate the light from the LED 102, preventing it from being diffused and failing to reach the human body, thus improving the therapeutic effect of the therapeutic lamp 100.

[0063] In the embodiment where the total reflection surface 122 is provided, the outer surface of the lamp holder 12 (i.e., the total reflection surface 122) can be cup-shaped and inverted on the substrate 11 to concentrate the light emitted by the lamp bead 102.

[0064] Please refer to Figure 8 , Figure 9 and Figure 10 In some embodiments, the total reflection surface 122 is configured such that the propagation direction of the reflected light from at least a portion of the total reflection surface 122 is at an angle to the normal direction of the substrate 11.

[0065] This requires that the light reflected by the total internal reflection surface 122 is not parallel, so that at least a portion of the light rays can be incident at an angle onto the exit surface of the substrate 11, and of this portion of light rays, at least a portion can be as... Figure 10 As shown in the optical path on the right, the light propagates along the tangent of the substrate 11 within the substrate 11 and gradually exits, so that the entire therapeutic lens 10 is lit up during operation. Figure 9The process of propagation along the tangent direction of the substrate 11 is not shown in the figure, but it can be seen that the reflected light through the total reflection surface 122 is not parallel light. Therefore, at least part of the light can propagate along the tangent direction of the substrate 11, ensuring that the entire emitting surface of the physiotherapy lens 10 is in a light-emitting state during operation.

[0066] Please refer to Figure 8 and Figure 10 In some embodiments, the bottom of the placement slot 121 is an optical surface 1211, which has positive or negative optical power; the optical surface 1211 is used to shape the emitted light of at least a portion of the lamp beads 102 before it is incident on the substrate 11.

[0067] The optical surface 1211 shapes the emitted light from the lamp bead 102. The optical surface 1211 can be a spherical, aspherical, or freeform surface, and the aforementioned optical power can be the equivalent optical power of a spherical surface, an aspherical surface, or a freeform surface. The optical surface 1211 can both diffuse the emitted light from the lamp bead 102, thereby increasing the irradiation area, and converge the emitted light from the lamp bead 102, thereby increasing the energy flux density of light irradiating the human body, thus improving therapeutic efficacy.

[0068] Please refer to Figure 10 In some embodiments, the optical surface 1211 is configured such that the propagation direction of at least a portion of the emitted light is at an angle to the normal direction of the substrate 11.

[0069] This requires that the light emitted from optical surface 1211 is not parallel, such as... Figure 10 As shown, the light emitted from at least a portion of the optical surface 1211 can be incident at an angle onto the light-emitting surface of the substrate 11, thereby achieving the desired effect. Figure 10 The light path shown on the right propagates along the tangential direction of the substrate 11, ensuring that the exit surface of the physiotherapy lens 10 is in a light-emitting state throughout the entire working process of the physiotherapy lens 10.

[0070] Please refer to Figure 2 and Figure 4 ,or Figure 5 and Figure 7 In some embodiments, the number of lamp holders 12 provided on a substrate 11 is four; the four lamp holders 12 on a substrate 11 are arranged in a square array and are arranged adjacent to each other.

[0071] When the number of lamp holders 12 is too large, the surface area of ​​the substrate 11 will also increase due to the limitation of the size of the lamp beads 102. This makes it difficult to light up the entire substrate 11 even if there is light propagating along the tangential direction of the substrate 11, forming a weak light area similar to a dark area. When the number of lamp holders 12 is too small, it is difficult to meet the user's needs for multiple wavelengths of emitted light. Therefore, when the number of lamp holders 12 is four, it can ensure that the area of ​​the substrate 11 is not too large, that the entire therapeutic lens 10 is lit, and that a sufficient number of different wavelengths can be emitted from the same therapeutic lens 10.

[0072] Furthermore, when a substrate 11 is provided with four lamp holders 12, the four lamp holders 12 are arranged adjacently in a square row, which can minimize the surface area of ​​the substrate 11 occupied by the four lamp holders 12, which is beneficial to reducing the volume of the therapeutic lens 10 of the substrate 11.

[0073] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 In some embodiments, a light-diffusing portion 111 is provided on the side of the substrate 11 near the placement groove 121; the light-diffusing portion 111 is a protrusion protruding from the surface of the substrate 11 and / or a groove recessed into the surface of the substrate 11; there are multiple light-diffusing portions 111, and the multiple light-diffusing portions 111 are arranged in an array on the substrate 11; the light-diffusing portion 111 is used to scatter light that propagates in the substrate 11 and along the tangential direction of the substrate 11.

[0074] As can be seen, the light-scattering section 111 makes the surface of the substrate 11 irregular. The light-scattering section 111 arranged in an array can scatter the light propagating in the substrate 11, thereby improving the uniformity of the light emitted from the substrate 11.

[0075] exist Figure 6 In the illustrated embodiment, the light-diffusing portion 111 is a protrusion, but it can also be a recess, and its shape is not fixed; in the same embodiment, both protrusions and recesses can be provided simultaneously. The arrangement of multiple light-diffusing portions 111 can be an irregular array or a regular array. Furthermore, the light-diffusing portion 111 can be provided at any position on the substrate 11 where the lamp holder 12 is not provided.

[0076] Please refer to Figure 2 and Figure 5 In some embodiments, the physiotherapy lens 10 further includes a mounting post 13, which is disposed on the side of the substrate 11 near the placement groove 121 and extends from the substrate 11 in a direction away from the substrate 11; the mounting post 13 is used to mount the physiotherapy lens 10 on a preset mounting position on the physiotherapy lamp 100.

[0077] The mounting post 13 can have different shapes to fit the mounting structure on the therapeutic lamp 100. For example, the mounting post 13 can be snap-fitted into the mounting structure on the therapeutic lamp 100. The mounting post 13 can also simply serve as a retaining and limiting element. For example... Figure 5 The mounting post 13 shown has a protrusion at the end away from the substrate 11. Figure 3 The mounting post 13 shown also has a protrusion at the corresponding position. The protrusion can mate with the positioning hole on the physiotherapy lamp to fix the physiotherapy lens 10 in a preset position. As mentioned above, the substrate 11 can also abut against the housing 101 (or panel or other structures). In this way, the structure that mates with the protrusion and the housing 101 can clamp and fix the physiotherapy lens 10 from both sides.

[0078] Mounting column 13 can also be connected to physiotherapy lamp 100 by welding or bonding.

[0079] The mounting post 13 allows multiple LED beads 102 (as mentioned earlier, the installation of the physiotherapy lens 10 also has a fixing effect on the LED beads 102, so installing the physiotherapy lens 10 is also installing the LED beads 102) to share the same mounting post 13 of the physiotherapy lens 10, thereby simplifying the overall installation structure of the physiotherapy lens 10 and the lamp assembly, which is beneficial to the miniaturization of the physiotherapy lamp.

[0080] Please refer to Figure 1 This utility model also proposes a physiotherapy lamp 100, which includes the aforementioned physiotherapy lens 10. The specific structure of the physiotherapy lens 10 is as described in the above embodiments. Since this physiotherapy lamp 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0081] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
