[0036] Figure 1 is a schematic structural diagram of a phototherapy device provided by an embodiment of the present utility model. Refer to Figure 1 , the phototherapy device includes a transparent flexible lamp panel 10 and a control component 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 facing away from each other; the control component 20 is located on the first side of the transparent flexible lamp panel 10; a conductive circuit 11 with a preset path and a plurality of MiniLED lamp beads 12 are arranged on the second side of the transparent flexible lamp panel 10; the control component 20 is electrically connected to the plurality of MiniLED lamp beads 12 through the conductive circuit 11.

[0037] Specifically, when using the phototherapy device, the user needs to attach it to the part that requires phototherapy. At this time, the second side of the transparent flexible light board 10 is the side close to the skin. A conductive circuit 11 with a preset path and a plurality of MiniLED beads 12 are arranged on the second side of the transparent flexible light board 10; the control component 20 is electrically connected to the plurality of MiniLED beads 12 through the conductive circuit 11. The control component 20 supplies power to the plurality of MiniLED beads 12 through the conductive circuit 11 to control the plurality of MiniLED beads 12 to emit light and achieve the phototherapy function. During the phototherapy process, if you want to observe the phototherapy effect midway, a non-transparent phototherapy device needs to stop phototherapy and remove the phototherapy device. Therefore, by setting the transparent flexible light board 10, the phototherapy effect can be observed through the transparent flexible light board 10.

[0038] At the same time, in order to achieve a better phototherapy effect, it is necessary to distribute the MiniLED beads 12 at multiple positions on the second side surface of the transparent flexible light board 10. The plurality of MiniLED beads 12 are connected by the conductive circuit 11. Therefore, it is necessary to make the conductive circuit 11 distributed on the second side surface of the transparent flexible light board 10, that is, the distribution of the conductive circuit 11 needs to match the shape of the transparent flexible light board 10. Therefore, the conductive circuit 11 with a preset path is set. Among them, the overall conductive circuit 11 needs to match the shape of the transparent flexible light board 10, but the specific path can be set according to the actual situation, and the circuit does not need to be a single whole. Multiple paths can be set according to the shape of the transparent flexible light board 10, and all of them can be electrically connected to the control component 20. Exemplarily, if the shape of the transparent flexible light board 10 is in the shape of "butterfly wings", in order to ensure a better phototherapy effect, it is necessary to distribute the MiniLED beads 12 on the surface of the transparent flexible light board 10 in the shape of "butterfly wings". At this time, since the positions of the plurality of MiniLED beads 12 are relatively scattered, it is difficult to connect them with a single conductive circuit 11. Therefore, multiple conductive circuits 11 can be used, and all the multiple conductive circuits 11 are electrically connected to the control component 20.

[0039] It should be noted that the transparent flexible light board 10 is a double-sided board, and its first side and second side are conductively connected. Therefore, after the control component 20 is in electrical contact with the second side, the conductive circuit 11 and the MiniLED beads 12 on the first side can be controlled.

[0040] A light therapy device provided by the present utility model comprises a transparent flexible lamp panel and a control component; along the thickness direction of the transparent flexible lamp panel, the transparent flexible lamp panel includes a first side and a second side facing away from each other; the control component is located on the first side of the transparent flexible lamp panel; a conductive circuit with a preset path and a plurality of MiniLED lamp beads are arranged on the second side of the transparent flexible lamp panel; the control component is electrically connected to the plurality of MiniLED lamp beads through the conductive circuit; the above technical solution solves the problems that the existing light therapy devices are non-transparent in design, resulting in the inability to clearly observe the light therapy effect, and at the same time, the appearance of the non-transparent light therapy devices is not beautiful enough; by providing a transparent flexible lamp panel, the light therapy device is transparent in design, which can better observe the light therapy effect, and at the same time, the transparent design further improves the aesthetic degree.

[0041] Wherein, when the light therapy device is an eye patch, in order to ensure a good fitting effect around the eyes, the transparent lamp panel needs to be a flexible substrate, and the thickness range of the transparent flexible lamp panel 10 is set to be 0.05 - 0.5 mm to have good bending properties. In other embodiments of the present utility model, the light therapy device can also be a pimple patch, a face patch, a facial mask, etc., and the thickness of the transparent flexible lamp panel 10 can be determined according to the bending requirements of specific products, which is not limited herein.

[0042] Optionally, the light therapy device further comprises a first transparent flexible encapsulation layer 30; along the thickness direction of the transparent flexible lamp panel 10, the first transparent flexible encapsulation layer 30 is located on the second side 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.

[0043] Specifically, since the second side of the transparent flexible lamp panel 10 is the side close to the skin, and the skin is a moist environment, oils on the skin, wet skin care products, and device / skin interface materials such as gel patches may all penetrate into the device, that is, the light therapy device in this case. In order to prevent the transparent flexible lamp panel 10 from being damaged by moisture due to being close to the skin, a first transparent flexible encapsulation layer 30 is provided on the second side of the transparent flexible lamp panel 10, that is, the side in contact with the skin, to avoid the conductive circuit 11 and the plurality of MiniLED lamp beads 12 of the transparent flexible lamp panel 10 from being affected by moisture.

[0044] Optionally, the light therapy device further includes a second transparent flexible encapsulation layer 40; along the thickness direction of the transparent flexible lamp panel 10, the second transparent flexible encapsulation layer 40 is located on the side of the control component 20 away from the transparent flexible lamp 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 edges of the first transparent flexible encapsulation layer 30 and the second transparent flexible encapsulation layer 40 are connected, and an enclosed space is formed inside; the transparent flexible lamp panel 10 and the control component 20 are located in the enclosed space formed by the first transparent flexible encapsulation layer 30 and the second transparent flexible encapsulation layer 40.

[0045] Specifically, since the light therapy device often works in a humid environment, in order to prevent the transparent flexible lamp panel 10 and the control component 20 from being damaged by water ingress, a second transparent flexible encapsulation layer 40 is also provided. The shapes of the first transparent flexible encapsulation layer 30 and the second transparent flexible encapsulation layer 40 are the same as the shape of the transparent flexible lamp panel 10. The edges of the first transparent flexible encapsulation layer 30 and the second transparent flexible encapsulation layer 40 are connected, and an enclosed space is formed inside. The transparent flexible lamp panel 10 and the control component 20 are located in this enclosed space to achieve a further waterproof effect. Exemplarily, if the transparent flexible lamp panel 10 is in a half-moon shape, the corresponding first transparent flexible encapsulation layer 30 and second transparent flexible encapsulation layer 40 are both in a half-moon shape, and the transparent package formed by them is also in a half-moon shape.

[0046] It should be noted that the materials of the transparent flexible lamp panel 10 and the transparent flexible encapsulation layer can be one or several of polyimide (PI), polyethylene terephthalate (PET), and thermoplastic polyurethane rubber (TPU); at the same time, different transparency rates can be set according to different application scenarios of the light therapy device. Exemplarily, if the light therapy device is an eye patch, since the skin of the eye is relatively sensitive, 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 with a high transparency rate, that is, the transparency rate is greater than 95%. If the light therapy device is a face mask, at this time, in addition to the light therapy effect, the face mask also has a shielding effect on the face. Therefore, its transparency rate requirement is relatively low, and usually its transparency rate is set to be greater than or equal to 50% and less than 95%. Among them, the transparency rate of the light therapy device can be understood as the proportion of light transmitted through the light therapy device. After the user wears the light therapy device, a corresponding proportion of light can pass through. At this time, the light reflected from the user's skin surface passes through the light therapy device and enters the eyes of the observer, so that the light therapy effect can be observed.

[0047] Optionally, referring to Figure 1, the control component 20 includes a circuit board 21 and a power supply component 22; along the thickness direction of the transparent flexible light board 10, the circuit board 21 is connected between the power supply component 22 and the transparent flexible light board 10. The power supply component 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 an alternative embodiment of the present utility model, the power supply component 22 includes circuit elements and a battery, and is covered by a driving upper cover. Among them, the circuit board 21 can be a rigid circuit board or a flexible circuit board; for example, when the light therapy appliance is an eye patch, it needs to fit the user's face at this time, so it needs to have good bending performance, that is, a flexible circuit board is used.

[0048] Optionally, Figure 2 is a schematic diagram of the welding of a transparent flexible light board and a circuit board provided by an embodiment of the present utility model, Figure 3 is Figure 2 a side cross-sectional view of the shown welding schematic diagram; referring to Figure 2 、 Figure 3 , a solder pad 13 is provided on the surface of the transparent flexible light board 10 facing the circuit board 21; a plurality of first rivet through holes 201 are provided on the circuit board 21; a plurality of second rivet through holes 202 are provided on the solder pad 13; the plurality of first rivet through holes 201 and the plurality of second rivet through holes 202 are arranged in one-to-one alignment; a hollow rivet 203 sequentially passes through an aligned first rivet through hole 201 and a second rivet through hole 202 to fix the transparent flexible light board 10 and the circuit board 21, so that the solder pad 13 and the side of the circuit board 21 facing the transparent flexible light board 10 are in electrical contact.

[0049] Specifically, referring to Figure 3 , a plurality of first rivet through holes 201 are provided on the circuit board 21, and a plurality of second rivet through holes 202 aligned with the first rivet through holes 201 are provided on the solder pad 13. In this way, after the rivet sequentially passes through a first rivet through hole 201 and a second rivet through hole 202, the transparent flexible light board 10 and the circuit board 21 are fixed, so that the solder pad 13 and the side of the circuit board 21 facing the transparent flexible light board 10 are in electrical contact. Thereby, the power supply component 22, the circuit board 21 and the transparent flexible light board 10 are electrically connected. At the same time, rivet connection is adopted, and the rivet process is relatively mature, which can improve efficiency, reduce costs, and increase the reliability of the light therapy appliance in a high-temperature and high-pressure environment during production.

[0050] Optionally, Figure 4 is another schematic diagram of the welding of a transparent flexible light board and a circuit board provided by an embodiment of the present utility model, Figure 5 is Figure 4 a side cross-sectional view of the shown welding schematic diagram; referring to Figure 4 、 Figure 5, on one side surface of the transparent flexible light board 10 facing the circuit board 21, there are pads 13, and the circuit board 21 is welded to the transparent flexible light board 10 through the pads 13, so as to be electrically connected to the transparent flexible light board 10.

[0051] Exemplarily, on one side of the circuit board 21 far from the skin surface, there is a through hole 211. The circuit board 21 is welded to the pad 13 through the through hole 211, that is, the pad 13 is exposed through the through hole 211. Therefore, spot welding is performed on the surface of the exposed part of the pad 13 in the through hole 211. In this way, the solder joints can be located in the through holes, which not only realizes the welding and fixing, but also prevents direct welding between the transparent flexible light board 10 and the circuit board 21, and the solder joints form bulges on the contact surface, thus affecting the compactness of the phototherapy appliance.

[0052] Optionally, Figure 6 is another side cross-sectional view of the welding between the transparent flexible light board and the circuit board provided by the embodiment of the present invention. Refer to Figure 6 , the circuit board 21 is a double-sided board, and the two sides in the thickness direction are conductively connected; on one side surface of the transparent flexible light board 10 facing the circuit board 21, there are pads 13, and the circuit board 21 is thermally pressed and connected to the pads 13 through the conductive glue layer 14.

[0053] Specifically, in an optional embodiment of the present invention, the circuit board 21 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 21 is conductively connected to the power supply element 22, the other side in the thickness direction, that is, the second side to be connected to the transparent flexible light board 10, is also conductively connected to the power supply element 22. At this time, the transparent flexible light board 10 can also be connected to the circuit board 21 by a thermal pressing method, that is, a conductive glue is coated between the pad 13 of the transparent flexible light board 10 and the second side of the circuit board 21 to form a conductive glue layer 14, and then it is further fixed by a thermal pressing process, realizing the electrical connection between the power supply element 22, the circuit board 21 and the transparent flexible light board 10.

[0054] It should be noted that, Figure 3 、 Figure 5 and Figure 6Side cross-sectional view of the welding of the transparent flexible lamp board and the circuit board for different embodiments of the same phototherapy device. That is, according to actual requirements, the transparent flexible lamp board 10 and the circuit board 21 can be connected by through-hole electric welding, conductive glue hot pressing, or riveting, which is not limited herein. When the transparent flexible lamp board 10 and the circuit board 21 are connected by through-hole electric welding, since spot welding is a conventional technical means and the operation is simple, the manufacturing efficiency can be improved while reducing the process cost. However, since the manufacturing environment of the phototherapy device is a high-temperature and high-pressure environment, for example, the temperature in its mold is between 100-120 °C and the pressure is between 13-15 bar. However, the solder joints of through-hole spot welding are prone to cracking under a high-pressure environment above 10 bar, which may cause a risk of poor contact between the transparent flexible lamp board 10 and the circuit board 21. When the transparent flexible lamp board 10 and the circuit board 21 are connected by hot pressing with conductive glue, the conductive glue can not only reduce the process cost but also compress the thickness of the phototherapy device and increase the product compactness. However, the conductive glue layer also has poor reliability in a high-temperature and high-pressure environment, that is, the melting point of the conductive glue is usually between 60-80 °C, while the manufacturing environment of the phototherapy device is between 100-120 °C, so it is easy to cause the conductive glue to melt, thereby affecting the connection effect between the transparent flexible lamp board 10 and the circuit board 21. When the transparent flexible lamp board 10 and the circuit board 21 are connected by rivets, since rivet connection is a mature process and the mechanical connection operation is simple, the manufacturing efficiency of the phototherapy device can be increased; at the same time, the rivets are not affected by the high-temperature and high-pressure environment, and the connection is firm, which can ensure the reliability of the phototherapy device.

[0055] Optionally, Figure 7 is a partial structural schematic diagram of a phototherapy device provided by an embodiment of the present invention. Refer to Figure 7 , one or more magnetic metal sheets 15 are provided on the side of the transparent flexible lamp board 10 facing the second transparent flexible encapsulation layer 40; thus, when the phototherapy device is placed in the storage box, it can be automatically adsorbed and positioned through the magnetic metal sheets 15. Specifically, Figure 8 is a structural schematic diagram of a storage box for a phototherapy device provided by an embodiment of the present invention. Refer to Figure 8 , the storage box 100 includes an upper shell 110 and a lower shell 120. The lower shell 120 internally includes a groove for accommodating the phototherapy device, and the shape of the groove matches that of the phototherapy device; when the phototherapy device is placed in the groove of the storage box, the magnetic metal sheets 15 are located on the side in contact with the lower shell 120 of the storage box, thereby adsorbing and fixing the phototherapy device in the groove of the lower shell 120 of the storage box.

[0056] Optionally, the circuit board 21 is a double-sided board, conductively connected on both sides in the thickness direction; a battery management circuit (not shown in the figure) is provided on the side of the circuit board 21 in electrical contact with the power supply component 22, and two charging probes 212 are provided on the side of the circuit board 21 facing away from the power supply component 22; through holes 101 for the charging probes 212 to pass through are correspondingly provided on the transparent flexible light board 10. Continuing to refer to Figure 6 , a charging seat (not shown in the figure) is provided in the groove of the lower shell 120 of the storage box 100. When the light therapy device is placed in the storage box 100, it is magnetically 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 device are designed to match, that is, when the light therapy device is magnetically adsorbed and fixed in the storage box 100, its charging probe 212 can just pass through the through hole 101 to be electrically connected to the charging seat in the storage box, and the charging seat thus charges the power supply component 22.

[0057] In an optional embodiment of the present invention, the light therapy device is an eye patch, the transparent flexible light board 10 is in a half-moon shape, and the control component 20 is located at one end of the transparent flexible light board 10 in contact with the outer corner of the eye.

[0058] Specifically, the control component 20 of the existing eye patch is often arranged in the middle of the outside of the eye patch, which will block the user's line of sight and thus result in poor user experience. Referring to Figure 1 , in this application, the control component 20 is arranged at one end of the transparent flexible light board 10 in contact with the outer corner of the eye, which can avoid the control component 20 blocking the user's line of sight and thus improve the user experience.

[0059] The light therapy device according to the embodiment of the present utility model is provided with a transparent flexible lamp panel. On the side of the transparent flexible lamp panel that fits the skin, a conductive circuit with a preset path and a plurality of MiniLED lamp beads for realizing the light therapy effect are provided 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. At the same time, since the human eye can observe a plurality of MiniLED lamp beads through the transparent flexible lamp panel, and the distribution of the MiniLED lamp beads matches the shape of the flexible lamp panel, various arrangement shapes can be formed, thereby increasing the aesthetic degree. At the same time, a first transparent flexible encapsulation layer and a second transparent flexible encapsulation layer are provided, so that the transparent flexible lamp panel and the control component are located in the closed space formed by the first transparent flexible encapsulation layer and the second transparent flexible encapsulation layer, avoiding water ingress and damage of the transparent flexible lamp panel and the control component when working in a humid environment, and further improving the waterproof effect of the light therapy device. At the same time, since the transparent flexible lamp panel and the control component need to be placed in the closed space formed by the first transparent flexible encapsulation layer and the second transparent flexible encapsulation layer, it is necessary to make the transparent flexible lamp panel and the control component have a compact structure. Therefore, it is necessary to improve the welding method of the circuit board in the transparent flexible lamp panel and the control component, that is, through holes are provided on the side of the circuit board away from the skin surface, and the pads of the transparent flexible lamp panel are exposed through the through holes. Therefore, spot welding is performed on the surface of the pad portion exposed in the through holes, so that the solder joints are located in the through holes, preventing direct welding between the transparent flexible lamp panel and the circuit board, and the solder joints form bulges on the contact surface, thus affecting the compactness of the light therapy device. Or a conductive glue layer is used to connect the transparent flexible lamp panel and the circuit board, that is, a double-sided circuit board is used, which is electrically connected on both sides in the thickness direction. That is, after the first side of the circuit board is electrically connected to the power supply element, the other side in the thickness direction, that is, the second side to be connected to the transparent flexible lamp panel, is also electrically connected to the power supply element. At this time, a conductive glue is coated between the pad of the transparent flexible lamp panel and the second side of the circuit board to form a conductive glue layer, and then it is further fixed through a hot pressing process, realizing the electrical connection between the power supply element, the circuit board and the transparent flexible lamp panel. At the same time, since the conductive glue layer is a whole layer structure, the problem that the compactness of the light therapy device is poor due to the bulges formed by the scattered solder joints can be avoided.
