Description

Phototherapy hair-growing lamp assembly and application thereof

Technical Field

The application relates to the technical field of phototherapy, in particular to a phototherapy hair-growing lamp component and application thereof.

Background

In the middle and late 20 th century, techniques such as micro-light therapy (Low Light Laser Treatment) and photo bio-modulation (PBM) have been developed, and light is used as a means for treating diseases in the medical field (Michael r.hamulin, ying-Ying Huang, handbook of Photomedicine, CRC Press). Several studies have shown that red to near infrared illumination has been found to help promote regeneration of collagen and skin cells and other tissues, and can be used in the fields of anti-wrinkle cosmetology, promotion of wound healing, spot and scar removal, hair growth and the like (Chan Hee Nam et al Dermatologic Surgery,2017;43:371-380,Daniel Barolet,Semin Cutan Med Surg,27:227-238,2008,Yongmin Jeon,Adv.Mater.Technol.2018,1700391).

There are currently some hair growing cap products (https:// good. Kalla. Com/product/9018726. Html) that use an array of LEDs (fig. 2 a) or lasers (fig. 2 b) as light sources. There are also some patent applications on hair growing caps, such as the use of laser as a light source, for example, patent applications CN102015021a, CN110038231a, etc., as well as the use of semiconductor light emitting diodes LEDs as a light source, for example, CA2683090A1, CN106139413a, CN107676638A, etc., and the use of LEDs or laser as a light source but conducted by optical fibers, for example, CN108553765A, CN109173075A, etc. These products or patent applications are all arranged in an array of LED or laser light sources inside a housing. Both the LED and the laser are high-intensity point light sources which generate heat during use, so that the light sources generally need to be integrated with a heat dissipation device to reduce the temperature, and the lamp beads need to be arranged at a certain distance for heat dissipation when used in an array form. This results in three disadvantages of this type of pilatory cap. First, such a hair growing cap is thick and heavy because it must incorporate a heat sink in view of heat dissipation, and must be located at a distance from the scalp for safety, which is uncomfortable to wear on the head. Second, in an array arrangement, the LEDs or lasers are all independent at a certain position, and there is a space between them, which results in uneven light emission, so that uneven illumination may be uneven with phototherapy or multiple phototherapy is required in different areas. Third, to cover the entire head, a large number of light sources, sometimes up to 200 beads, are required, which increases the difficulty of screening, assembling and maintaining the beads. Finally, the hair growing caps are generally fixed in shape, cannot be adapted to various head shapes, so that the phototherapy effect and experience feel are poor for partial users, and the products are generally used only in fixed places and are not portable.

Patent application CN111601459a discloses a build circuit board of a hair growing cap, two circuit boards can build a cap-shaped circuit board, wherein the build circuit board comprises a circuit board body, the circuit board body comprises a butt joint edge and a circumferential edge, the butt joint edge corresponds to the butt joint edge of the other build circuit board, the circumferential edge corresponds to the edge of the open end of the shell of the hair growing cap, and two ends of the circumferential edge are respectively connected with two ends of the butt joint edge; the peripheral edge of the circuit board is provided with a shear notch which is V-shaped and has a first shear angle which is 31-41 degrees when the cap-shaped circuit board is not constructed and is 0-2 degrees when the cap-shaped circuit board is constructed. Meanwhile, the application also discloses that the phototherapy hair growing cap is further manufactured by integrating a laser light source on the circuit board. First, the application requires that two circuit boards be butted to construct a cap circuit board, which must have a butted edge, which results in a gap in the constructed cap circuit board and increases the difficulty of assembly. Secondly, the application makes the plane circuit board into a curved surface by forming the V-shaped shear notch on the circumferential edge to form the cap-shaped circuit board, and further the lap joint part can be used for enclosing and fixing the shear notch, but the enclosing angle and the shape of the cap-shaped circuit board actually prepared by the application are fixed, and the shape can not be randomly adjusted at any time according to various head shapes. And the cap in this application is adapted to different sized heads by selecting the use or non-use of the pad. Finally, the light source in this application uses a laser light source, which also suffers from the problems of heating and uneven illumination as stated above.

In contrast, an OLED is a surface light source, a cold light source, is not dazzling, and has a light and thin nature, so that it is very easily integrated onto a flexible substrate. This makes OLEDs an ideal light source choice for wearable applications, and patent applications related thereto have also covered various fields in recent years. Patent application CN205108772U, CN204951964U and CN102481456a both mention that an OLED light source can be used as a wearing product for phototherapy. Application CN203694423U and application CN109173071a before the present inventors mention the use of OLED for the preparation of phototherapy masks; the prior patent applications CN111481833a, CN111514466a, CN111544774A and CN112754764A of the present inventors respectively mention the use of OLED for the preparation of hair growing caps, slimming plastomer, phototherapy socks and band-aid. Although patent application CN111481833a also mentions the use of OLED light emitting panels for the preparation of hair growing caps, it requires that they must be used in combination with photovoltaic devices and that the OLED light emitting panels must be integrated on a fixed hair growing cap.

Based on the above-mentioned practical problems, the present application provides a phototherapy hair-growing lamp assembly and a phototherapy cap comprising the same.

A typical single layer OLED device structure is shown in fig. 1 a. Among them, the OLED device 100 includes an anode layer 101, a Hole Injection Layer (HIL) 102, a Hole Transport Layer (HTL) 103, an Electron Blocking Layer (EBL) 104, an emission layer (EML) 105, a Hole Blocking Layer (HBL) 106, an Electron Transport Layer (ETL) 107, an Electron Injection Layer (EIL) 108, and a cathode layer 109. Wherein the light emitting layer 105 typically further comprises at least one host material and at least one light emitting material, and the electron blocking layer 104 and the hole blocking layer 106 are optional layers. Hole injection layer 102 may be a single material layer, such as a conventional HAT-CN; the hole injection layer 102 may also be a hole transport material doped with a proportion of a p-type conductivity dopant material. A single-layer OLED device may also include multiple light-emitting layers, and OLED device 110 as shown in fig. 1b may include one red light-emitting layer 105a and one deep red light-emitting layer 105b. Wherein, the red light emitting layer 105a may be realized by doping a red light emitting material with a red light host material; similarly, the deep red light emitting layer 105b may be implemented by doping a red host material with a deep red light emitting material. Note that although OLED device 110 has two light emitting layers, it is still considered a single layer device because it has only one set of transport material systems. An adjusting layer can be added between the two light-emitting layers to control the position of the composite light-emitting area, so that the color change caused by the drift of the light-emitting area under different electric driving is realized. For example, at low current densities, OLEDs may emit predominantly red light, promoting wound healing, and at high current densities, OLEDs may emit deep red light, playing a hair-growing role. It is of course also possible to produce a single-layer device with three light-emitting layers on the basis of the OLED device 110, for example by continuously superimposing a red light, a deep red light, a near-infrared light-emitting layer. Techniques for fabricating OLEDs using single layer device structures are well known to those skilled in the art and are not described in detail herein.

The OLED device may also be implemented in a stacked structure, a schematic structure of a stacked OLED device 200 is shown in fig. 1c, which includes a first light emitting unit 201 and a second light emitting unit 202, wherein the light emitting units 201 and 202 include organic layers similar to those of the OLED device 100, and the two light emitting units are connected with a charge generating layer 111, and an anode 101 and a cathode 109 are disposed at the bottom and the top of the stacked OLED device 200, respectively. The charge generation layer 111 may further include an n-type material layer and a p-type material layer for conducting electrons and holes, respectively. The charge generation layer may further comprise a buffer layer material, and reference may be made in particular to patent application US2021119162A1. The stacked OLED device shown in fig. 1c is a dual cell structure, where the light emitting cells 201 and 202 may be two red light emitting cells, and the stacked device is advantageous for improving current efficiency and device lifetime, which is typically the structure commonly used in OLED lighting. Similarly, three red light emitting units may also be stacked, as shown in a three-layer stacked OLED device 210 in fig. 1d, comprising a first light emitting unit 201, a second light emitting unit 202 and a third light emitting unit 203, each connected by charge generating layers 111 and 121, with an anode 101 and a cathode 109 disposed at both ends of the device. Of course, each light emitting unit may emit light of a different color, for example, the first light emitting unit emits red light having a wavelength of 610-640nm, the second light emitting unit emits red light having a wavelength of 640-700nm, and the third light emitting unit emits near infrared light having a wavelength of 700nm or more. Techniques for using stacked device structures are well known to those skilled in the art and are not described in detail herein.

On the basis of the above device, a cross-sectional view of an OLED light-emitting panel is shown in fig. 3 a. The OLED light-emitting panel 300 includes a substrate 301, an OLED device 310, a pair of contact electrodes 303 electrically connected to the OLED device 310, a package 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 substrate 301 may be rigid such as glass, preferably flexible, including but not limited to ultra thin flexible glass, PET, PEN, PI, and the like. In particular, the substrate 301 may be a material (e.g., a Polyimide material) that has been previously applied to the support base in solution form, and cured and planarized for device fabrication. After the device is prepared, the device is peeled off from the supporting base plate by using laser and is transferred onto other flexible substrates according to the requirement. The OLED device 310 may be a bottom light emitting device or a top light emitting device, which is preferable because of its higher light emitting efficiency. The OLED device 310 may have a single layer structure or a stacked structure, which is preferable because it has a longer lifetime at the same brightness and because the thicker film layer is advantageous for improving the production yield. The organic material in OLED device 310 may be vapor deposited in a vacuum chamber in a thermal vapor form, or may be partially or even entirely formed 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 encapsulation layer 302 may be glass adhered to the device by UV curing glue, preferably a thin film encapsulation layer, and the thickness of the encapsulation layer is 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. If both the substrate 301 and the encapsulation layer 302 are flexible, then the entire OLED light-emitting panel is flexible; 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 version, the adhesive structure 304 may be an FPC bezel and the front cover film 305 may be a sheet of plastic film that provides mechanical support. A specific description of the use of FPC boards to drive OLED light emitting panels can be found in patent application US20190376650A1, which is incorporated by reference in its entirety, which is not within the scope of coverage of the present 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 region. The front cover film 305 may be a combination of the above. Additional thin film encapsulation layers 306 may be coated on 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 here. In fig. 3d, the rear cover film 307 is covered onto the substrate 301. The rear cover membrane 307 may be used for mechanical support. When the OLED is a bottom light emitting device, the rear cover film 307 may be a light extraction layer and transparent. The rear cover film 307 may be a combination of the above. Such an OLED light-emitting panel is one of the basic constituent elements in the present application.

Light of a plurality of different wavelength bands can be generated on one OLED light emitting panel in the following ways. The first is to design a pixelized layout on the same OLED light emitting panel and then drive each pixel independently, or group pixels and then drive different groups independently. The pixels here typically have a light emitting area in the order of millimeters, i.e. a minimum size of more than 1mm, preferably more than 5mm. For example, an OLED light-emitting panel 500 shown in fig. 4a may include an OLED substrate 501 on which a series of OLED devices 502 are patterned, where the devices share the same thin film encapsulation layer 503, and each light-emitting unit is an OLED device, and the whole OLED light-emitting panel is a light source. In this case, metal wires may be arranged on the panel while preparing the anode or the cathode, so as to electrically connect the OLED devices 502, and the method of metal wires is well known to those skilled in the art and will not be described herein. Different OLED devices are controlled through an external driving device, so that different devices emit light with different colors, or the same device works under different currents, and multiple colors are realized. A variation of this approach is an OLED light-emitting panel 510 as shown in fig. 4b, comprising one OLED substrate 501, a series of OLED devices 502, but each sharing a separate encapsulation layer 513, and preferably a thin film encapsulation layer. At this time, different OLED devices 502 can be connected not only through metal wires, but also through FPC circuit boards, so that the electrical conductivity and the complexity of the circuit are greatly improved. Also, single or multiple OLED devices 502 can be independently driven through these electrical connections. In both cases, if light of different colors is to be emitted, a metal mask can be used to vapor deposit different device structures for different OLED devices, especially to change the material of the light emitting layer; reference may also be made to applications CN111081892a and CN111081891a, all of which use the same structure of independent unit multiple light emitting layers, with the color change being achieved by the movement of the compound region at different operating points. The OLED substrate 501 in the two schemes may be hard or flexible, and is preferably flexible. Alternatively, the individual OLED light emitting panels may be arranged in an array, as shown in fig. 4c, where each light emitting panel comprises an individual substrate 521, an OLED device 502 and an individual encapsulation layer 513. The advantage of this arrangement is that an inflexible OLED light-emitting panel and/or an inflexible encapsulation layer can be chosen, as long as the area is small enough, the light source after forming the array can still have a certain flexibility. The individual OLED light emitting panels may be cut from the same motherboard, for example, all using the same individual unit multiple light emitting layer structure, or may be reassembled by selecting devices of different structures from different motherboards. The scheme has the advantages that devices can be screened, the yield is improved, and the color diversity of products is also increased. The independent light emitting panels shown in fig. 4c may be arranged and combined through FPC or front and rear cover films, etc. according to the requirement to form a lattice physically connected to each other, and specific reference may be made to the method disclosed in CN208750423U, which is not the content of the study of the present application and will not be described herein. Also, the panels may be independently controlled to give different operating currents. The array arrangement can realize multicolor light emission and zonal control.

Fig. 5a-5d show a schematic view of a phototherapy hair-growing lamp assembly 600 comprising a housing 601, an OLED light-emitting panel 602, a connection structure 603, a driving means 604. The housing 601 is preferably flexible and can be further divided into a central area a and two wing areas B, but the whole housing is continuously unified, instead of being formed by splicing several parts, wherein a plurality of OLED light emitting panels 6022 can be arranged on the central area a, as shown in fig. 5a, or only one OLED light emitting panel 6022 can be arranged, as shown in fig. 5 c. A plurality of OLED light emitting panels 6021 are provided on each wing of the both wing regions B. Preferably, the plurality of OLED light emitting panels have the same effective light emitting area, and more preferably, the plurality of OLED light emitting panels have the same layout, as shown in fig. 6a and 6c, which facilitates manufacturing and reduces costs. The OLED light emitting panel may emit light having a wavelength of 600-1400nm, preferably 630-1000 nm. The plurality of OLED light-emitting panels can emit light of different colors, for example, one of every two adjacent OLED light-emitting panels emits dark red light of 600-750nm and one emits near infrared light of 750-1400nm, so that light of different wave bands can be emitted to different areas of the head according to the needs of a user.
