Description

Phototherapy shaping clothes

Technical Field

The invention relates to a phototherapy shaping garment. And more particularly to a phototherapy shaping garment that combines elastic fabric and an OLED light source.

Background

Reports of various treatments of diseases with sunlight have been made early in the 18 th century, and by the second half of the 19 th century, sun-light therapy has become widespread. Photodynamic Therapy (PDT) is more developed in the beginning of the last century, and is widely used in the treatment of tumor diseases by combining various medicines. After half a century, technologies such as Low Light Laser Treatment (Low Light Laser Treatment) and photobiological modulation (PBM) have appeared, and both of them are applied to the medical field by using Light as a means for treating diseases (Michael r. A plurality of researches show that red light to near infrared light is helpful for promoting the regeneration of tissues such as collagen and skin cells, and can be applied to the fields of anti-wrinkle beauty, promotion of wound healing, freckle removal and scar removal (Chan Hee Nam et al, Dermatologic Surgery, 2017; 43: 371-chnol.2018, 1700391). FIG. 1 shows the penetration depth of different wavelengths in human skin, and it can be seen that light with a wavelength of 600-. FIG. 2 shows the absorption of light of different wavelength bands by different physiological substances (such as water, hemoglobin, oxyhemoglobin and melanin), and it can be seen that the optimal wavelength band window capable of passing through the skin tissue without loss is approximately between 600 and 1400nm (the wavelength band window is approximatelyhttps://www.thepaleomom.com/ joovv-red-light-therapy-for-weight-loss/). By combining the above two points, the red light with the wavelength of 600-1400nm and the near infrared light are the best choice for non-invasive treatment.

In recent years, a large number of phototherapy experiments aiming at red light and near infrared light show that the light also has the efficacy of shaping and losing weight. It has been found that first, red and near infrared light can promote the production of adenosine triphosphate in cells, and that an increase in adenosine triphosphate can improve metabolism, which corresponds to more heat consumption. Secondly, red light and near infrared light can promote the cell wall of fat cells to generate pores to cause the leakage of grease, finally the fat cells are shriveled and shrunk, and the effect of reducing the grease is achieved. Finally, the red light and the near infrared light can promote the growth of fiber cells, and the fiber cells can stimulate the production of collagen and can push the collagen to move between cell walls, thereby playing a role in tightening the skin. In recent years, clinical tests of a large number of low-power-consumption laser treatments prove that red light and near infrared light have the effects of reducing fat, tightening skin, inhibiting obesity and the like.

There are numerous applications for phototherapy with integrated light sources on a garment, for example US20090105791a1 and US20130310904a1 describe wearable phototherapy products with LEDs and optical fibers as light sources, respectively, but no particular garment is described in detail. In the aspect of slimming application, patent applications CN206081342U and CN108113787A disclose intelligent wearable slimming devices, but both are based on an LED red light module and a specific circuit control architecture, and do not specifically teach how to make the slimming device, nor relate to the application in the aspect of shaping. CN203400244U discloses a beauty and slimming rehabilitation heat preservation blanket, which also uses a red LED as a light source, but the use of the blanket is greatly influenced by occasions and weather, and the blanket cannot be used as a wearable device, and the blanket cannot be attached to the skin, so that the blanket is not an ideal slimming product. US8430919 and CN210170392U both disclose weight reducing waist bands using LEDs as light sources, which may be worn during exercise in combination with near infrared or red light illumination to achieve a fat reducing effect. However, such a belt is worn only around the waist, and because of the cumbersome shape of the LED, most importantly, the LED is a point light source, and is not suitable for large-area illumination applications.

CN105212291A discloses an intelligent underwear for women, especially a light source cotton sheet is arranged in a bra for treating hyperplasia of mammary glands, no specific description is provided for the preparation of the light source and the intelligent underwear, and most importantly, the light source cotton sheet is in the area of breasts, which is different from the shaping clothes with weight-reducing and shaping effects explained in the present invention in the treatment purpose and treatment position. CN201139874Y discloses a health underwear using semiconductor far infrared LED as light source, and also such health underwear is mainly used for promoting blood circulation, which is different from the therapeutic purpose of shaping clothes with slimming and shaping effects explained in the present application; and due to the volume of the LED and the heat dissipation device, the underwear is thick and heavy, is not attractive and can influence the action.

With the rise of Organic Light Emitting Devices (OLEDs) in the last 90 s of the century, the use of OLEDs as light sources for phototherapy devices has also begun to become possible. The OLED is made into an electroluminescent device by adopting a plurality of layers of organic thin films with nanometer thickness, has the light and thin physical essence and the potential of making a flexible light source, the characteristics of a cold light source enable the OLED to become the best choice of wearing products close to the body, and the essence of a surface light source enables the OLED to have unique advantages in large-area phototherapy application. Most importantly, the luminous efficiency of only white OLED in illumination is as high as 139lm/W in recent years, and the theoretical value can approach 250lm/W, making it an ideal light source. In addition, unlike the ordinary band UV spectrum in fluorescent or LED light sources, OLEDs do not produce UV illumination, which can reduce the side effects of UV irradiation. Examples of implementing masks and other phototherapy products using OLEDs as light sources are mentioned in patent applications CN109173071A, CN203694423U, etc.

The present inventors have described in prior patent applications CN210009521U and CN108783778A methods of treatment using OLEDs as light sources to make wearable devices, including the specific description of weight-reducing belts made with red or near-infrared OLEDs, but this only allows treatment of specific waists, not all over the body, and does not involve shaping effects.

At present, a lot of body-beautifying underclothes with different prices are in tight constraint by using extremely elastic fabrics added with lycra components and the like, and some body-beautifying underclothes are more in line with the experience of beauty parlors and the like and are matched with a certain adjusting and poking method to achieve the shaping effect. However, such body-building underwear does not substantially eliminate fat, and only temporarily pushes fat to a place not to be noticed, and returns to its original shape once wearing is stopped. However, if a red or near infrared light source with fat reduction can be integrated into such a tight fitting body suit, long-term shaping can be achieved. However, the fabric of the body-building underwear has strong elasticity, and in order to be worn as underwear at ordinary times, the integrated light source cannot be thick and heavy, and must be light, thin and flexible, which is not mentioned in the prior art for achieving the purpose of losing weight by using the LED light source for irradiation.

In 2017, Seonil Kwon et al disclose an OLED fiber, and the outer surface of a PET fiber is subjected to dip dyeing and etching in different organic solutions and finally subjected to vapor deposition to form a cathode, so that the OLED fiber capable of emitting light is prepared, and further can be woven to form a wearable product. However, the lifetime of OLED fibers prepared by solution methods is very low and cannot be practically achieved without improvement (Seonil Kwon et al Nano Lett.2018,18,1, 347-. Recently, Myung Sub Lim et al published a two-dimensionally expandable OLED architecture on Nano Letters, building longitudinal PDMS columns and transverse PDMS bridges between a stretchable PDMS substrate and a rigid OLED substrate, which can stretch and contract to bear most of the stress when the bottom PDMS substrate is stretched, so that the OLED on the upper layer can still work normally under the stretching (Myung Sub Lim et al, Nano letter. 2020,20,3,1526, 1535; DOI:10.1021/acs. Nanolett. 9b03657). The microscopic ingenious structure can realize the stretchable OLED, but the process is complex, the yield is low, the process is only limited in the academic scope, and the practicability of the stretchable OLED is still required to be further explored.

On the basis, the invention provides a novel phototherapy shaping garment, which is made of elastic fabric, can cover upper arms, waist, abdomen, buttocks and thighs, can be worn daily without limitation to sex, and can achieve the effects of reducing fat and tightening skin by using red or/and near infrared light emitted by an OLED light source while shaping the body by using the elastic fabric.

One light source that may be used in phototherapy shaping garments is a flexible Organic Light Emitting Device (OLED). Cross-sectional views of a flexible OLED light-emitting panel are shown in fig. 3a-3 d. The flexible OLED light emitting panel 300 includes a flexible substrate 301, an OLED device 310, a pair of contact electrodes 303 electrically connected to the OLED device 310, a flexible encapsulation layer 302 exposing the contact electrodes 303, and an adhesive structure 304 connecting the pair of contact electrodes 303 to an external driving circuit. The flexible substrate 301 may be a rigid ultra-thin glass (typically less than 200 microns thick), preferably flexible, including but not limited to ultra-thin flexible glass, PET, PEN, PI, etc. In particular, the flexible substrate 301 may be a material (e.g., a polyimide-based material) that is coated on the supporting substrate in the form of a solution in advance, cured, and planarized for device fabrication. After the device is prepared, the device is peeled off from the supporting substrate by using a laser and is transferred to other flexible substrates according to requirements, such as a lycra or lycra-doped elastic fabric. OLED device 310 can be a bottom emitting device or a top emitting device, with a top emitting device being preferred because of its higher light emitting efficiency. OLED device 310 can be a single layer structure or a stacked layer structure, with a stacked layer structure being preferred because the lifetime of the stacked device is longer at the same luminance and because the film layer is thicker to improve the production yield. The organic material in OLED device 310 may be formed by evaporation in a vacuum chamber by thermal evaporation, or may be formed partially or even entirely using a solution process, including but not limited to ink jet printing (ink jet printing), spin coating, organic vapor spray printing (OVJP), and the like. The flexible encapsulating layer 302 may be ultra-thin glass adhered to the device by a UV curable adhesive, preferably a thin film encapsulating layer, with a thickness generally above 10 μm, such as a single inorganic layer, or a thin film organic-inorganic alternating multilayer structure, and is formed by PECVD, ALD, printing, spin coating, etc. The contact electrode 303 may comprise at least one anode contact and one cathode contact. A front cover film 305 may be added to the OLED light emitting panel described above as shown in fig. 3 b. The front cover film 305 may be a Flexible Printed Circuit (FPC) board on which a pre-designed circuit is printed and electrically connected to the OLED device 310 through the adhesive structure 304. In another alternative, the adhesive structure 304 may be an FPC frame and the front cover film 305 may be a sheet of plastic film to provide mechanical support. A specific description of the use of an FPC board to drive an OLED light-emitting panel can be found in chinese patent application CN201810572632.3, which is incorporated by reference in its entirety and is not within the scope of coverage of this application. The front cover film 305 may also include a light extraction layer. When OLED device 310 is top-emitting, front cover film 305 is transparent in the light-emitting area. The front cover film 305 may be a combination of the above. Additional thin film encapsulation layers 306 may be applied to one or both sides of the substrate 301 as shown in fig. 3 c. The front cover film may also be coated with an additional thin film encapsulation layer 306, but is not shown in this figure. In fig. 3d, a back cover film 307 is overlaid onto the substrate 301. The back cover film 307 may be used for mechanical support. When the OLED is a bottom-emitting device, the back cover film 307 may be a light extraction layer and transparent. The back cover film 307 may be a combination of the above. Such a flexible OLED light-emitting panel is one of the basic components in the present invention.

The flexible OLED light-emitting panel can emit red and near infrared light with the peak wavelength of 600-1400nm, preferably the peak wavelength of 600-1000nm, and more preferably the peak wavelength of 630-900 nm. The light with the wavelength of 635nm is proved to have the fat reducing effect by clinical experiments (as shown in figure 4, https:// www.thepaleomom.com/joovv-red-light-heat-for-weight-loss /), some light with the wavelength of 700-900nm near infrared can reach the deeper part under the skin, and in addition, the illumination with the wavelength of 630-660nm has the effects of regenerating the skin, eliminating scars and removing wrinkles. In some embodiments, some down-conversion materials may be coated on the light emitting face of the flexible OLED light emitting panel to down-convert red light to near-infrared radiation, common down-conversion materials including, but not limited to, organic dyes, quantum dot materials, and the like.

Different working points can be given to the flexible OLED light sources in different areas on the phototherapy shaping clothes, different flexible OLED light sources can emit different colors, or the flexible OLED light sources in the same area can work at different working points on different occasions. There are many ways to achieve this, the first being to design a pixelized layout on a flexible OLED light-emitting panel and then drive each pixel independently, or to group pixels and then drive different groups independently. The pixels here usually have a light-emitting area in the order of millimetres, i.e. a minimum area greater than 1mm²Preferably greater than 5mm². For example, a flexible OLED light emitting panel 500 shown in fig. 5a may include a flexible OLED substrate 501 on which a series of OLED devices 502 are patterned, and these devices share the same thin film encapsulation layer 503, in this case, each light emitting unit is an OLED device, and the whole flexible OLED light emitting panel is a light source. In this case, the metal wires may be arranged on the panel at the same time of preparing the anode or the cathode for electrically connecting the OLED devices 502, and the method of the metal wires is well known in the art and will not be described herein. Is electrically driven by external powerThe OLED device is controlled, so that different devices can emit light with different colors, or the same device works under different currents, and multiple colors can be realized. A variation of this is a flexible OLED light emitting panel 510 as shown in fig. 5b comprising a flexible OLED substrate 501, a series of OLED devices 502, but each device enjoys a separate encapsulating layer 513, and preferably the encapsulating layer is a thin film encapsulating layer. At this time, the different OLED devices 502 can be connected through metal wiring, and can also be electrically connected through an FPC circuit board, thereby greatly improving the possibility of conductivity and circuit complexity. Also, a single or multiple OLED devices 502 can be independently driven through these electrical connections. Under the two conditions, if light with different colors is emitted, different device structures can be evaporated on different OLED devices by using a metal mask, and particularly, the material of a light emitting layer is changed; it is also possible to refer to the structures described in applications CN2020100639006 and CN2020100571291, all of which use the same structure of independent unit multiple light emitting layers, with the variation of color being achieved by the movement of the recombination zone at different operating points. Alternatively, individual OLED light emitting panels may be arranged in an array, as shown in fig. 5c, where each light emitting panel comprises an individual substrate 521, an OLED device 502 and an individual encapsulating layer 513. The advantage of this arrangement is that a non-flexible OLED substrate and/or a non-flexible encapsulation layer can be used, as long as the area is small enough, and the light source formed into the array still has a certain flexibility, but preferably at least one of the substrate and the encapsulation layer is flexible. The individual OLED light emitting panels may be cut from the same motherboard, for example, using the same individual unit multi-light emitting layer structure, or may be reassembled by selecting different structures of devices from different motherboards. The scheme has the advantages that the device can be screened, the yield is improved, and the color diversity of products is also improved. The independent light-emitting panel shown in fig. 5c can be arranged and combined through FPC or front and back cover films, etc. to form a lattice physically connected with each other as required, and it is specifically referred to the method disclosed in CN208750423U, and it is not in the scope of the present invention. Also, the panels mayTo be independently controlled to give different operating currents. The array arrangement can realize multicolor light emission and zone control, for example, long-term phototherapy can be performed on waist and abdomen parts, and short-term phototherapy can be applied to parts with more muscles or less obesity on legs or upper arms. The local illumination can further reduce the power consumption and save energy.

Although the above-described OLED light-emitting panel is flexible, it cannot be intrinsically stretched. If the OLED device is directly fabricated on a stretchable substrate, the device itself (especially the cathode and anode) may be broken or damaged by strong stress during stretching, thereby affecting the normal operation of the device. On the other hand, a large part of the effects of shaping the underwear come from the tight effect of the elastic fabric, and the underwear can play roles in supporting the body, moving fat, shaping curves and the like. In fact, many body shaping underwear on the market contain elastic fabric components in different proportions, and elastic fabric refers to fabric with length of 1.5 times or more when the fabric is stretched but not stretched, and is called high-elasticity fabric if the fabric is stretched 4 times or more than the non-stretched length. The elastic fabric can be a fabric with elasticity of the fiber, and includes, but is not limited to, polyamide fiber (nylon or nylon), polyurethane fiber (spandex), polyester fiber (dacron), lycra fiber and the like, wherein especially lycra fabric has the highest elasticity and can be stretched to 4-6 times of the original length, and belongs to a high-elasticity fabric. The elastic material may be a material that is wholly stretchable by using a non-elastic material but by using a specific knitting method, for example, a knitted material having a certain elasticity. How to skillfully integrate the flexible OLED light-emitting panels on an elastic fabric is the core content of the invention.

The function of integral extension and retraction is achieved by adhering part of the flexible OLED light-emitting panel and the fabric of the shaping clothes. An example of such a method is illustrated in fig. 6a-6 b. Specifically, fig. 6a shows a cross-sectional view 100 of a shaping garment material before stretching, which includes an elastic material 101 in a non-stretched state, wherein the elastic material 101 has a first length or a first area, a plurality of flexible OLED light-emitting panels 102 are electrically connected 104 to each other, and the flexible OLED light-emitting panels 102 have a light-emitting surface (in the direction shown by the solid black arrows) and a non-light-emitting surface, and the light-emitting surface is far away from the elastic material 101, and the non-light-emitting surface faces the elastic material 101. Two ends of the electrical connection 104 are respectively fixed on electrical connection points of two adjacent flexible OLED light-emitting panels, and the electrical connection points may be electrical contacts or some welding point on an FPC. The electrical connections 104 may be metal wires, the actual length of which should be greater than the distance between the electrical connection points of two adjacent light-emitting panels to each other at the maximum stretch of the elastic fabric. Thus, in the unstretched state 100 of FIG. 6a, the electrical connection 104 shows a curved wire shape, indicating that the electrical connection points on two adjacent flexible OLED panels are at a distance shorter than the actual length of the electrical connection wire 104. Note that although shown in a bent state, the electrical connection 104 may be other conductive materials or structures that are stretchable, such as being straightened when in the unstretched state 100 and then stretched to a reduced width and increased length. The electrical connection 104 may be a metal film patterned in advance, for example, in a zigzag shape (fig. 7a), a great wall shape (fig. 7b), an S shape (fig. 7c), or a coil shape (fig. 7d), and may have a certain ductility when stretched. A portion of the non-light emitting surface of the flexible OLED light emitting panel 102 is connected to the elastic fabric 101 by an adhesive structure 103. The adhesive structure 103 includes, but is not limited to, viscose, velcro, elastic bands, buttons, straps, fibers made of the elastic fabric itself, and the like. It should be noted that although the adhesion structure 103 is illustrated as a dot, it may actually be a one-dimensional stripe or a two-dimensional surface along the bottom of the light-emitting panel. Furthermore, the adhesive structure 103 may have a plurality of lines or a surface, and a main purpose thereof is to fix a portion of the flexible OLED panel to the elastic fabric, while the remaining portion is not fixed and is in a free state. Preferably, the adhesive structure is a detachable structure such as a button, so that the flexible OLED light-emitting panels can be easily detached from the elastic fabric and then installed back when needed, and the elastic fabric with the light-emitting panels detached can be washed normally. The condition 110 is formed when the elastic material is stretched in one dimension (as shown by the hollow arrow in fig. 6 b), where the elastic material is in an extended state 1011 and has a second length or a second area, the second length being greater than the first length, and/or the second area being greater than or equal to the first area. The adhesive structures 103 on the elastic fabric 1011 are also stretched relative to each other, as are electrical connections 1041. In contrast, electrical connection 1041 in the stretched state 110 of FIG. 6b bends less than electrical connection 104 in the unstretched state 100, but the distance between the two electrical connection points is elongated, which is believed to be a change in the physical form of the electrical connection, from a bent state to a stretched state. Thus, in this case, the elastic material 1011 at the bottom drives the adhesive structure 103 to pull the distance between the flexible OLED lighting panel 102, but the flexible OLED lighting panel itself is not subjected to an external force. This allows stretching of the shaping garment without affecting the performance of the OLED itself.

Similarly, FIGS. 8a-8b illustrate another example of integrating a flexible OLED light emitting panel onto an elastic facing material. Fig. 8a shows an unstretched state 200 of an elastic material 201, on which a plurality of flexible OLED light-emitting panels 202 are also present, and which are electrically connected 204 to each other. The light emitted by the flexible OLED light-emitting panel is shown by the black solid arrows in the figure, namely the light-emitting surface is far away from the elastic fabric, and the non-light-emitting surface is towards the elastic fabric. A portion of the bottom of the flexible OLED light emitting panel 202 is connected to the elastic fabric 201 by an adhesive structure 203. The adhesive structure 203 may be a fibrous or malleable structure (as shown in fig. 7a-7 d). The elastic fabric has a first length or a first area. When the elastic panel is stretched to extend to the extended state 210 shown in fig. 8b, the elastic panel is extended to a 2011 state having a second length or a second area, and the second length is greater than the first length and/or the second area is greater than or equal to the first area. Some or all of the malleable adhesive structure 203 may also be elongated to a state 2031. Note that with respect to fig. 8a, the electrical connections 204 in fig. 8b are hardly deformed, i.e. have no or only a weak change in physical form, and likewise the distance of the flexible OLED light-emitting panels 202 from each other is hardly changed, which is different from the example of fig. 6a and 6 b. The method can still achieve the effect that the flexible OLED panel is not influenced at all while the elastic fabric is stretched.

The above examples can also be explained from the plan views 9a-9 c. Fig. 9a shows the unstretched condition 400, where it can be seen that there are a plurality of flexible OLED light emitting panels 402 on an elastic fabric 401 arranged in a 3x 4 matrix, with electrical connections 403 between the 4 flexible OLED light emitting panels 402 in each row, and one other electrical connection 404 for one flexible OLED panel in a row that may be further connected to an electrical drive. The electrical connection 403 is now in an unextended state and thus appears curved in fig. 9 a. The elastic fabric has a first area. When in the one-dimensional extended state 410 (as shown in fig. 9 b), the elastic material is stretched towards both sides along the hollow arrows to form a state 411, and the electrical connection thereon is also stretched into a straight line 413, so that the physical form is changed. At this time, the elastic fabric has a second area, and the second area may be greater than or equal to the first area. Note that here is merely illustrative, and the electrical connection 413 may be understood as being stretched to the limit, and the actual stretching may be between the unstretched condition 400 of fig. 9a and the limit stretched condition 410 of fig. 9b, i.e., the length of the electrical connection is between 403 and 413. At this point, the lateral distance (direction parallel to the stretching direction) of the flexible OLED light emitting panels 402 from each other is also pulled apart, but the panels themselves are not stretched. On this basis, fig. 9c further shows a state 420 when the elastic fabric is under two-dimensional stretch, i.e. stretched both up and down and left and right, when the elastic fabric 421 has a third area, the third area being larger than the first area. At this time, not only the column pitch of the flexible OLED light-emitting panel 402 is expanded, but also the line pitch thereof is extended. It will of course be appreciated that although there are blank areas between the rows in the figure, it is also possible to make electrical connections like 403 between different rows of the OLED panel.

In fig. 6-9, the flexible OLED light emitting panels before and after being stretched have a spacing therebetween, which may make the light emitting area discontinuous. One improvement is shown in figures 10a-10 c. In the unstretched state 600 (fig. 10a), the elastic material 601 is attached to a portion of the bottom of the flexible OLED lighting panel 602 by an adhesive structure 603, while the two OLED panels overlap each other with a portion 605. This overlap may be achieved by the flexible panels 602 being forced against each other to form a certain bend as shown in fig. 10a, or by the two panels 612 being slightly out of alignment 615 in a horizontal plane as shown in fig. 10b at 610, where a certain difference in height of the adhesive structures 613 is required. It is easy to overlap the two flexible light-emitting panels, and the description is omitted here. In both fig. 10a and 10b the elastic panel 601 has a first length or first area, in the extended state 620 shown in fig. 10c, where the elastic panel is extended to 6011 and has a second length or second area, the second length being greater than the first length, and/or the second area being greater than or equal to the first area. And the two flexible OLED light-emitting panels 622 are also pulled apart from each other and just extend to a state where the edges of each other meet. The advantage of this mode is that the illumination is substantially continuous before and after stretching.

This can likewise be seen in the plan views 11a-11 c. The unstretched state 700 in fig. 11a corresponds to the state in fig. 10a or 10b, when the elastic material 701 has a first area on which three flexible OLED light emitting panels 702 are provided and which are electrically connected 703 to each other, with overlapping portions 705 between each two OLED panels. The stretched state 710 of fig. 11b corresponds to the case of fig. 10c, where the elastic panel is in a stretched state 711, having a second area, the second area being equal to or greater than the first area. The three flexible OLED light-emitting panels 702 are just seamless from each other and the electrical connections are also in a half-stretched state 713, which is also different from 703 in physical form. When further stretched to the state 720 corresponding to fig. 11c, the elastic panel is further stretched to 721 degrees and has a third area, which is equal to or greater than the first area. Gaps begin to appear between the three flexible OLED panels 702 and the electrical connections are further stretched to the extreme state 723 as a straight line with a much larger change in physical form.

Fig. 12a-12c illustrate an example of a phototherapy shaping garment. Fig. 12a shows the overall upper body effect of the set of phototherapy shaping suit 800, which includes an upper garment portion 810 and a lower garment portion 820, and further includes

electric drivers

814 and 824 for respectively powering the upper garment portion 810 and the lower garment portion 820. The electric drives 814 and 824 may be batteries or other interfaces capable of providing power, such as a power plug, a USB interface (e.g., USB configuration, Micro-USB interface, Type-C interface, etc.), a wireless charging device (e.g., an electromagnetic induction charging device, a magnetic resonance charging device, a radio frequency wireless charging device, etc.), and so on. The electric driving device may further comprise a circuit control system for implementing zone control or working point control of the flexible OLED light source, and the circuit control system includes, but is not limited to, a CPU, a microprocessor, a chip, an FPC board, and a memory. In the detailed illustration of the jacket portion 810 of fig. 12b, it can be seen that the jacket 810 further comprises a harness portion 811, an upper arm portion 812 and a torso (or lumbo-abdominal back) portion 813. Strap portion 811 has a buckle structure 8111, and similarly, upper arm portion 812 has a buckle structure 8121, and body portion 813 has a buckle portion 8131. Note that while the

fastener structures

8111, 8121, and 8131 are shown in the figures as similar to hook and loop fastener forms, any other fastener structure may be used to secure and tightly wrap the body shaping garment, including, but not limited to, zippers, straps, buttons, and the like. The upper arm portion 812 also includes an elastomeric fabric 8120 having a first area in an unstretched state (812), and a flexible OLED lighting panel 8122 integrated thereon and electrical connections 8123 between the panels. In the enlarged view in the lower right corner we show the upper arm portion 812 in a stretched condition 8124, where the elastic fabric is seen to stretch into a plane 8125 and have a second area, which is equal to or greater than the first area, while the electrical connection between the panels is stretched to 8126, which changes the physical form. Similarly, the body portion 813 also contains an elastic fabric 8130 on which a flexible OLED light emitting panel 8132 and electrical connections 8133 to each other are integrated. The back of the torso also incorporates an electric drive 814, although the location and form of the particular electric drive may be adjusted according to the actual needs and is outside the scope of the present invention. It should be noted that although an array of flexible OLED light-emitting panels is shown, a single panel may be used, with only a portion of the non-light-emitting surface of the panel being adhered to the elastomeric facing. The number of the actual panels can be arranged according to the size of the shaping clothes, the wearing part, the OLED process and other aspects of comprehensive consideration. When wearing such a coat, the coat can be wrapped around the body like a backpack, the strap portions 811 are fixed by the buckle structure 8111, then the trunk portion 813 is wrapped around the waist and abdomen, fat at the position is allocated to be accumulated in the chest direction or the hip direction as required, then the fixing is performed by the buckle structure 8131, and finally the upper arm portion 812 is wrapped around the arm in sequence and fixed by the buckle structure 8121. Similarly, fig. 12c shows a detail of the bottom garment 820, wherein the left view shows the overall effect of the bottom garment 820 when opened and the right view is a half-sectional view in its stretched state. It can be seen that the bottom garment 820 comprises an elastic fabric 8210 in an unstretched state having a first area on which a flexible OLED lighting panel 8212 and electrical connections 8213 to each other (unstretched state) are integrated, the bottom garment 820 further comprising snap structures 8211 and electrical drivers 824. In the stretched state 8200 (right panel), the elastic fabric is stretched 8214 and has a second area, which is equal to or greater than the first area. The flexible OLED lighting panel 8212 thereon is not affected but the electrical connections between them are also elongated 8215, changing physical form. Similarly, when wearing, the lower garment is attached to the crotch from bottom to top and then sequentially wraps the legs (or can be seated to enhance stability), and then is fixed by the fastener structure 8211. It should be noted that the above designs are only examples, and the design of the shaping garment can be modified as needed, or even customized and designed differently according to the treatment requirements of the wearer. For example, the lower garment may further comprise a lower leg portion, or the lower garment may be formed in a high waist style, etc. In addition, the shaping clothes designed for women can further comprise a bra part or female elements such as lace and the like.

In order to avoid adverse reactions such as allergy caused by direct contact of skin with various artificial materials on the OLED light source, a skin-friendly protective layer can be further arranged on the flexible OLED light-emitting panel. Fig. 13 shows a partial cross-sectional structure 900 of a phototherapy shaping garment, which comprises an elastic fabric 902, a flexible OLED light source 901 (which may be a light-emitting panel or a plurality of panels arranged in an array) is disposed on the elastic fabric 902, the light-emitting surface of the flexible OLED light source 901 is far from the elastic fabric 902, and further, an optional down-conversion material 903 is disposed on the light-emitting surface of the OLED light source 901. An additional skin-friendly protective layer 904 may be disposed over the flexible OLED light source 901. The adhesion structure and electrical connections are not shown in fig. 13 due to the partial cross-sectional structure. In some embodiments, the elastic fabric 902 may also comprise all or part of the front cover film 305 in a bottom light emitting device or the back cover film 307 in a top light emitting device. The skin-friendly protective layer 904 may be made of common cloth, preferably natural textiles such as cotton, hemp, silk, etc., or may be made of the same material as the elastic fabric 902. In particular, in order to make the light emitted from the OLED light source 901 pass through the skin-friendly protective layer 904 as much as possible, the skin-friendly protective layer 904 uses a sparse weaving method or even a hollow-out method as much as possible to allow the light to pass through. In particular, the skin-friendly protective layer 904 may be sparsely textured in areas that coincide with the OLED light source 901 or light-emitting areas above the light source, allowing light to pass through, while the conventional texturing is used in areas where there is no OLED light source or no light-emitting areas (e.g., the areas between the OLED panels in fig. 6 and 8). The skin-friendly protective layer 904 may also comprise all or part of the front cover film 305 in a top emission device or the back cover film 307 in a bottom emission device. The skin-friendly protective layer 904 is required to shield the contact electrodes and the FPC board from direct contact with the human body.

The phototherapy shaping clothes described by the invention is light, thin and skin-friendly, and can be worn under outer clothes daily to achieve the shaping effect. Meanwhile, the OLED light source is powered to emit red or near infrared light, so that the effects of reducing fat and tightening the skin are achieved. Because the dark red and near infrared light which is insensitive to human eyes are mostly used, and the light emitting surface faces the inside of the human body, the visual interference can not be caused. The special adhesion structure can realize the random disassembly of the light source, so that the shaping clothes can be normally washed after the light source is disassembled.
