[0039] FIG. 1 is a structural schematic diagram of a light therapy appliance provided by an embodiment of the present application. Referring to FIG. 1, the light therapy appliance includes a transparent flexible lamp panel 10 and a control assembly 20. Along the thickness direction of the transparent flexible lamp panel 10, the transparent flexible lamp panel 10 includes a first side and a second side which are away from each other. The control assembly 20 is located on the first side of the transparent flexible lamp panel 10. The second side of the transparent flexible lamp panel 10 is provided with a conductive circuit 11 with a preset path and a plurality of Mini Light Emitting Diode (MiniLED) lamp beads 12. The control assembly 20 is electrically connected with the plurality of MiniLED lamp beads 12 through the conductive circuit 11.

[0040] Exemplarily, when the user uses the light therapy appliance, he needs to attach it to the part that needs light therapy, at this time, the second side of the transparent flexible lamp panel 10 is the side close to the skin, and the second side of the transparent flexible lamp panel 10 is provided with the conductive circuit 11 with a preset path and a plurality of MiniLED lamp beads 12; the control assembly 20 is electrically connected with the plurality of MiniLED lamp beads 12 through the conductive circuit 11, and the control assembly 20 supplies power to the plurality of MiniLED lamp beads 12 through the conductive circuit 11 to control the plurality of MiniLED lamp beads 12 to emit light, thereby realizing the light therapy function. During the light therapy, if the user wants to observe the effect of the light therapy in the middle of the light therapy, the non-transparent light therapy appliance needs to stop the light therapy and remove the light therapy appliance, so the transparent flexible lamp panel 10 is provided, and the effect of the light therapy can be observed through the transparent flexible lamp panel 10.

[0041] At the same time, in order to achieve better light therapy effect, it is necessary to make the MiniLED lamp beads 12 distributed at multiple positions on the second side surface of the transparent flexible lamp panel 10, and the plurality of MiniLED lamp beads 12 are connected through the conductive circuit 11, so it is necessary to make the conductive circuit 11 distributed on the second side surface of the transparent flexible lamp panel 10, that is, the distribution of the conductive circuit 11 needs to match the shape of the transparent flexible lamp panel 10, so the conductive circuit 11 with a preset path is set. The overall conductive circuit 11 needs to match the shape of the transparent flexible lamp panel 10, but the actual path of the conductive circuit 11 can be set according to actual needs, and the circuit does not need to be a whole one, but can be set as multiple ones according to the shape of the transparent flexible lamp panel 10, and they are all electrically connected with the control assembly 20. Exemplarily, if the shape of the transparent flexible lamp panel 10 is "butterfly wing" shape, in order to ensure better light therapy effect, it is necessary to make the MiniLED lamp beads 12 distributed on the surface of the "butterfly wing" shaped transparent flexible lamp panel 10, at this time, since the positions of the plurality of MiniLED lamp beads 12 are relatively dispersed, it is difficult to use a conductive circuit 11 to connect them, so multiple conductive circuits 11 can be used, and the multiple conductive circuits 11 are all electrically connected with the control assembly 20.

[0042] It should be noted that the transparent flexible lamp panel 10 is a double-sided panel, and the first side and the second side are conductively connected, so after the control assembly 20 is electrically connected with the second side, it can further control the conductive circuit 11 and the MiniLED lamp beads 12 on the first side.

[0043] The application provides a light therapy tool, which comprises a transparent flexible lamp panel and a control component; the transparent flexible lamp panel comprises a first side and a second side which are opposite to each other along the thickness direction of the transparent flexible lamp panel; the control component is located on the first side of the transparent flexible lamp panel; the second side of the transparent flexible lamp panel is provided with a conductive circuit with a preset path and a plurality of MiniLED lamp beads; the control component is electrically connected with the plurality of MiniLED lamp beads through the conductive circuit; the above embodiment solves the problem that the light therapy tool in the related art is non-transparent, which leads to the fact that the light therapy effect cannot be clearly observed, and the appearance of the light therapy tool with non-transparent design is not beautiful enough; the transparent flexible lamp panel is arranged, so that the light therapy tool is transparent, and the light therapy effect can be better observed, and the transparent design improves the degree of beauty.

[0044] In an embodiment, when the light therapy tool is an eye patch, in order to ensure good fitting effect around the eyes, the transparent lamp panel needs to be a flexible substrate, and the thickness of the transparent flexible lamp panel 10 is arranged to be 0.05-0.5 millimeters (mm) to have good bending property. In other embodiments of the application, the light therapy tool can also be a pimple patch, a face patch, a mask and the like, and the thickness of the transparent flexible lamp panel 10 can be determined according to the bending requirement of the actual product.

[0045] In some embodiments, the light therapy tool further comprises a first transparent flexible encapsulation layer 30; the first transparent flexible encapsulation layer 30 is located on the second side of the transparent flexible lamp panel 10 along the thickness direction of the transparent flexible lamp panel 10; the projection of the first transparent flexible encapsulation layer 30 on the first plane is the same as the shape of the transparent flexible lamp panel 10 and covers the transparent flexible lamp panel 10; the first plane is the plane where the transparent flexible lamp panel 10 is located.

[0046] For example, since the second side of the transparent flexible lamp panel 10 is the side close to the skin, and the skin is a humid environment, the oil, wet skin care products and gel patches and other skin interface materials on the skin can penetrate into the device, i.e., the light therapy tool of the application. In order to prevent the transparent flexible lamp panel 10 from being damaged due to close contact with the skin, the first transparent flexible encapsulation layer 30 is arranged on the second side of the transparent flexible lamp panel 10, i.e., the side in contact with the skin, so as to prevent the conductive circuit 11 and the plurality of MiniLED lamp beads 12 of the transparent flexible lamp panel 10 from being damp.

[0047] In some embodiments, the light therapy device further comprises a second transparent flexible encapsulation layer 40; the second transparent flexible encapsulation layer 40 is located on the side of the control component 20 away from the transparent flexible light panel 10 along the thickness direction of the transparent flexible light panel 10; the projection of the second transparent flexible encapsulation layer 40 on the first plane completely coincides with the projection of the first transparent flexible encapsulation layer 30 on the first plane; the first transparent flexible encapsulation layer 30 and the second transparent flexible encapsulation layer 40 are edge-connected and form a closed space inside; the transparent flexible light panel 10 and the control component 20 are located in the closed space formed by the first transparent flexible encapsulation layer 30 and the second transparent flexible encapsulation layer 40.

[0048] For example, since the light therapy device often works in a humid environment, in order to avoid water damage to the transparent flexible light panel 10 and the control component 20, a second transparent flexible encapsulation layer 40 is also provided. The first transparent flexible encapsulation layer 30 and the second transparent flexible encapsulation layer 40 have the same shape as the transparent flexible light panel 10, the first transparent flexible encapsulation layer 30 and the second transparent flexible encapsulation layer 40 are edge-connected and form a closed space inside, and the transparent flexible light panel 10 and the control component 20 are located in the closed space to achieve a waterproof effect. For example, if the transparent flexible light panel 10 is half-moon shaped, the corresponding first transparent flexible encapsulation layer 30 and second transparent flexible encapsulation layer 40 are also half-moon shaped, and the transparent encapsulation body formed thereby is also half-moon shaped.

[0049] It should be noted that the material of the transparent flexible light panel 10 and the transparent flexible encapsulation layer can be one or more of polyimide (PI), polyethylene terephthalate (PET), and thermoplastic polyurethane rubber (TPU). At the same time, different transparency can be set according to different application scenarios of the light therapy device. For example, if the light therapy device is an eye patch, the eye skin is relatively sensitive, so it is necessary to monitor the light therapy effect of the eye in real time. At this time, the eye patch needs to be set to have a high transparency, i.e., the transparency is greater than 95%. If the light therapy device is a mask, at this time, the mask has a shielding effect on the face in addition to the light therapy effect, so the transparency requirement is relatively low, and the transparency is usually set to be greater than or equal to 50% and less than 95%. The transparency of the light therapy device can be understood as the proportion of light transmitted by the light therapy device. After the user wears the light therapy device, a corresponding proportion of light can be transmitted, at this time, the light reflected by the user's skin surface can pass through the light therapy device and enter the observer's eye, and the light therapy effect can be observed.

[0050] In some embodiments, referring to FIG. 1, the control assembly 20 comprises a circuit board 21 and a power supply element 22; the circuit board 21 is connected between the power supply element 22 and the transparent flexible lamp panel 10 along the thickness direction of the transparent flexible lamp panel 10. The power supply element 22 supplies power to the circuit board 21, so as to drive the MiniLED lamp beads 12 to emit light through the conductive circuit 11. In some embodiments of the present application, the power supply element 22 comprises a circuit element and a battery, and is covered by a driving cover. Among them, the circuit board 21 can be a rigid circuit board or a flexible circuit board; for example, when the phototherapy device is an eye patch, it is necessary to be attached to the face of the user, so it is necessary to have good bending performance, that is, a flexible circuit board is used.

[0051] In some embodiments, FIG. 2 is a schematic diagram of welding a transparent flexible lamp panel and a circuit board according to an embodiment of the present application, and FIG. 3 is a side sectional view of the welding schematic diagram shown in FIG. 2; referring to FIGS. 2 and 3, the transparent flexible lamp panel 10 is provided with a solder pad 13 on the side surface facing the circuit board 21; the circuit board 21 is provided with a plurality of first rivet through holes 201; the solder pad 13 is provided with a plurality of second rivet through holes 202; the plurality of first rivet through holes 201 and the plurality of second rivet through holes 202 are arranged in alignment; a hollow rivet 203 penetrates a first rivet through hole 201 and a second rivet through hole 202 arranged in alignment in sequence, so as to fix the transparent flexible lamp panel 10 and the circuit board 21, and make the solder pad 13 and the circuit board 21 electrically contact with the side of the transparent flexible lamp panel 10.

[0052] For example, referring to FIG. 3, the circuit board 21 is provided with a plurality of first rivet through holes 201, and the solder pad 13 is provided with a plurality of second rivet through holes 202 aligned with the first rivet through holes 201, so that after the hollow rivet penetrates a first rivet through hole 201 and a second rivet through hole 202 in sequence, the transparent flexible lamp panel 10 and the circuit board 21 are fixed, and the solder pad 13 and the circuit board 21 electrically contact with the side of the transparent flexible lamp panel 10. Thus, the power supply element 22, the circuit board 21 and the transparent flexible lamp panel 10 are electrically connected. At the same time, rivet connection is adopted, and the rivet process is relatively mature, which can improve the efficiency, reduce the cost, and increase the reliability of the phototherapy device in the high-temperature and high-pressure environment during production.

[0053] In some embodiments, FIG. 4 is another schematic diagram of welding a transparent flexible lamp panel and a circuit board according to an embodiment of the present application, and FIG. 5 is a side sectional view of the welding schematic diagram shown in FIG. 4; referring to FIGS. 4 and 5, the transparent flexible lamp panel 10 is provided with a solder pad 13 on the side surface facing the circuit board 21, and the circuit board 21 is welded with the transparent flexible lamp panel 10 through the solder pad 13, so as to be electrically connected with the transparent flexible lamp panel 10.

[0054] For example, the circuit board 21 is provided with a through hole 211 on the side away from the skin surface, the circuit board 21 is welded with the solder pad 13 through the through hole 211, that is, the solder pad 13 is exposed through the through hole 211, thus the surface of the exposed part of the solder pad 13 in the through hole 211 is spot welded, so that the welding spot is located in the through hole 211, which not only realizes the welding fixation, but also prevents the welding between the transparent flexible lamp plate 10 and the circuit board 21, and the welding spot forms a bump on the contact surface, which affects the compactness of the phototherapy tool.

[0055] In some embodiments, FIG. 6 is another side view of the welding of the transparent flexible lamp plate and the circuit board according to the embodiments of the present application. Referring to FIG. 6, the circuit board 21 is a double-sided board, which is conductive on both sides in the thickness direction; the transparent flexible lamp plate 10 is provided with a solder pad 13 on the side surface facing the circuit board 21, and the circuit board 21 is hot-pressed and connected with the solder pad 13 through the conductive glue layer 14.

[0056] In some embodiments of the present application, the circuit board 21 is a double-sided board, which is conductive on both sides in the thickness direction, that is, after the first side of the circuit board 21 is conductively connected with the power supply element 22, the second side in the thickness direction, which needs to be connected with the transparent flexible lamp plate 10, is also conductively connected with the power supply element 22, at this time, the transparent flexible lamp plate 10 can also be connected with the circuit board 21 through the hot-pressing mode, that is, the conductive glue layer 14 is coated between the solder pad 13 of the transparent flexible lamp plate 10 and the second side of the circuit board 21, and then fixed through the hot-pressing process, so as to realize the electrical connection among the power supply element 22, the circuit board 21 and the transparent flexible lamp plate 10.

[0057] It should be noted that Figures 3, 5 and 6 are the transparent flexible lamp panel and the circuit board welding side view of different embodiments of the same light therapy appliance. That is, the transparent flexible lamp panel 10 and the circuit board 21 can be connected by through-hole electric welding, conductive glue hot-press connection or rivet connection according to actual needs. When the transparent flexible lamp panel 10 and the circuit board 21 are connected by through-hole electric welding, spot welding is a conventional technical means and easy to operate, so as to reduce the process cost and improve the production efficiency. However, the welding spot of the through-hole electric welding is easy to crack under the high pressure environment of more than 10 bar, so as to cause the risk of poor contact between the transparent flexible lamp panel 10 and the circuit board 21. When the transparent flexible lamp panel 10 and the circuit board 21 are connected by conductive glue hot-press connection, the conductive glue can not only reduce the process cost, but also compress the thickness of the light therapy appliance and increase the compactness of the product. However, the conductive glue layer 14 is also poor in reliability under the high temperature and high pressure environment, that is, the melting point of the conductive glue is usually 60-80°C, and the production environment of the light therapy appliance is between 100-120°C, so the conductive glue is easy to melt, thereby affecting the connection effect of the transparent flexible lamp panel 10 and the circuit board 21. When the transparent flexible lamp panel 10 and the circuit board 21 are connected by rivet connection, the rivet connection is a mature process and the mechanical connection is easy to operate, so as to increase the production efficiency of the light therapy appliance. At the same time, the rivet is not affected by the high temperature and high pressure environment, the connection is firm, and the reliability of the light therapy appliance can be ensured.

[0058] In some embodiments, Figure 7 is a partial structure diagram of a light therapy appliance provided by the embodiments of the present application. Referring to Figure 7, the transparent flexible lamp panel 10 is provided with at least one magnetic metal sheet 15 on the side facing the second transparent flexible encapsulating layer 40; so that when the light therapy appliance is placed in the storage box, the magnetic metal sheet 15 can be automatically attracted and positioned. For example, Figure 8 is a structure diagram of a light therapy appliance storage box provided by the embodiments of the present application. Referring to Figure 8, the storage box 100 includes an upper shell 110 and a lower shell 120, wherein the inside of the lower shell 120 includes a recess for accommodating the light therapy appliance, and the shape of the recess matches the light therapy appliance; when the light therapy appliance is placed in the recess of the storage box, the magnetic metal sheet 15 is located on the side in contact with the lower shell 120 of the storage box, so as to attract and fix the light therapy appliance in the recess of the lower shell 120 of the storage box.

[0059] In some embodiments, the circuit board 21 is a double-sided board, and both sides are conductive in the thickness direction; the side of the circuit board 21 in electrical contact with the power supply element 22 is provided with a battery management circuit, and the side of the circuit board 21 away from the power supply element 22 is provided with two charging probes 212; the transparent flexible lamp panel 10 is correspondingly provided with through holes 101 for the charging probes 212 to pass through. Referring to FIG. 6, the lower shell 120 of the storage box 100 is provided with a charging seat in the groove; when the light therapy tool is placed in the storage box 100, it is adsorbed and fixed in the groove by the magnetic metal sheet 15; since the magnetic adsorption position and the charging position of the light therapy tool are well matched, when the light therapy tool is adsorbed and fixed in the storage box 100, the charging probes 212 can pass through the through holes 101 and be electrically connected with the charging seat in the storage box, so that the charging seat charges the power supply element 22.

[0060] In some embodiments of the present application, the light therapy tool is an eye patch, and the transparent flexible lamp panel 10 is half-moon shaped, and the control assembly 20 is located at the end of the transparent flexible lamp panel 10 in contact with the tail of the eye.

[0061] For example, the control assembly 20 of the eye patch in the related art is often arranged at the middle of the outer side of the eye patch, which blocks the user's line of sight and causes poor user experience; referring to FIG. 1, in the present application, the control assembly 20 is arranged at the end of the transparent flexible lamp panel 10 in contact with the tail of the eye, which can avoid blocking the user's line of sight and improve the user experience.

[0062] The light therapy appliance of the embodiment of the application is provided with a transparent flexible lamp panel, the side of the transparent flexible lamp panel that is attached to the skin is provided with a conductive circuit with a preset path and a plurality of MiniLED lamp beads that realize the light therapy function, so as to perform light therapy on the skin surface; at this time, the light therapy effect on the skin surface can be observed in real time through the transparent flexible lamp panel, and at the same time, the human eye can observe the plurality of MiniLED lamp beads through the transparent flexible lamp panel, the distribution of the MiniLED lamp beads matches the shape of the flexible lamp panel, a plurality of arrangement shapes can be formed, and the aesthetic degree is thus increased; meanwhile, the first transparent flexible encapsulating layer and the second transparent flexible encapsulating layer are provided, so that the transparent flexible lamp panel and the control assembly are located in the closed space formed by the first transparent flexible encapsulating layer and the second transparent flexible encapsulating layer, and the transparent flexible lamp panel and the control assembly are prevented from being damaged by water when working in a humid environment, and the waterproof effect of the light therapy appliance is thus improved; meanwhile, since the transparent flexible lamp panel and the control assembly need to be placed in the closed space formed by the first transparent flexible encapsulating layer and the second transparent flexible encapsulating layer, the transparent flexible lamp panel and the control assembly need to have a compact structure, and therefore the welding mode of the circuit board in the transparent flexible lamp panel and the control assembly needs to be adjusted, that is, a through hole is provided on the side of the circuit board that is away from the skin surface, and the pads of the transparent flexible lamp panel are exposed through the through hole, so that the pads exposed in the through hole are spot-welded, so that the welding points are located in the through hole, and welding between the transparent flexible lamp panel and the circuit board is prevented, and the welding points form bumps on the contact surface, thereby affecting the compactness of the light therapy appliance; or the conductive glue layer is used to connect the transparent flexible lamp panel and the circuit board, that is, the circuit board is a double-sided board, and the two sides in the thickness direction are conductively connected, that is, after the first side of the circuit board is conductively connected with the power supply element, the second side in the thickness direction, that is, the side that needs to be connected with the transparent flexible lamp panel, is also conductively connected with the power supply element, at this time, the pads of the transparent flexible lamp panel and the second side of the circuit board are coated with conductive glue, a conductive glue layer is formed, and then the electrical connection between the power supply element, the circuit board and the transparent flexible lamp panel is realized through the hot-pressing process; meanwhile, since the conductive glue layer is an integral structure, the problem of poor compactness of the light therapy appliance caused by the bumps formed by the dispersed welding points can be avoided.
