Description

Phototherapy device

Technical Field

The present invention relates to a phototherapy device. And more particularly, to a phototherapy device that integrates a light source and a sound player.

Background

Technologies such as Low Light Laser Treatment (Low Light Laser Treatment) and photobiological modulation (PBM) appear in the middle and later stages of the 20 th century, and both of them are applied to the medical field by using illumination as a means for treating diseases (Michael r. Several studies have shown that red to near infrared illumination is found to help promote regeneration of tissues such as collagen and skin cells, and can be applied in the fields of anti-wrinkle cosmetology, promotion of wound healing, depigmentation, hair growth, etc. (Chan Hee Nam et al, dermatologic Surgery,2017, 371-380, daniel barolet, semin Cutan Med surg,27, 227-238,2008, yongmin jeon, adv.

Both the LED and the OLED can achieve the phototherapy effect as the light source. Generally, an LED has advantages of high luminance, low voltage, and long life as a point light source, but it is a point light source of high intensity and generally generates heat. Therefore, the LED light source generally integrates a heat dissipation device to reduce the temperature, and the lamp beads must be arranged at a certain distance for heat dissipation when used in an array form. Sometimes a heat sink must be added and must be at a distance from the face for safety. In the array arrangement, the LEDs are independent at certain positions with a spacing between them, which results in non-uniform light emission. In cosmetic treatments, such uneven illumination may result in uneven treatment or require multiple treatments in different areas. Fig. 2a and 2b are physical diagrams of two commercially available LED eye films, and it can be seen that the light source is a series of independent and spaced LED lamp beads. In order to ensure that the illumination effect can be achieved at a position without a light source, the light emitting intensity of a single LED lamp bead needs to be increased, the increase of the light emitting intensity further brings about the temperature rise and local over-high brightness, and the over-high brightness (such as 100,000nits) seriously affects the vision and even has the risk of damaging the eyeballs. For example, the product shown in fig. 2a measures the brightness of light to be about 120,000nits, and because of no good light shielding component, the light beam emitted by the light source reaches the human eyes after being diffusely reflected, and the high brightness causes that the human eyes cannot be opened basically when the product is worn, which seriously affects the use experience. Finally, to cover a larger facial area, a large number of LEDs, sometimes as many as 80, need to be used, which increases the difficulty of screening, assembling and maintaining the beads.

In contrast, OLED is a surface light source, a cold light source, is not glaring, and has a light and thin property, making it very easy to integrate into a flexible substrate. This makes OLEDs ideal light source options for wearable applications, and the related patent applications also cover various fields in recent years. The applicant of the present invention discloses a phototherapy glasses in the prior patent CN111538171B, on which a series of near-infrared OLED light-emitting panels are arranged at intervals to implement phototherapy on the eye region, and at the same time, the phototherapy glasses have a certain transmittance without affecting normal vision, but do not have the function of a sound player.

Utility model CN216318367U discloses a sleep-aiding eye mask with earphone function, which is integrated with OLED screen, but functions as display, rather than phototherapy, and the direction of light emission (i.e. display) is towards the outside of human face. CN113577570A, CN113101493A, CN204484476U, US20090005837A1 discloses an eyeshade with therapeutic effect, which integrates light sources and a sound playing device, but these light sources all need to be driven by ac power, and the emitted light all emits at a certain frequency to the eyeball of human eye, so as to achieve the therapeutic effect of stimulating the brain, and both block the eye and cannot watch the external environment. Utility model CN211326091U discloses a take sleep eye-shade of earphone function, and it has integrateed the LED fluorescent tube in one side that people's eye was kept away from to the sunshading board to just give out light to people's eye when needs are awaken up. CN106454577B and US20150209597A1 both disclose a device combining an eyeshade and a headset, but the light source integrated thereon is directly irradiating to human eyes, and also because the eyeshade shields human eyes, the external environment cannot be observed when the device is used. The eyecup disclosed in CN104888359a also has a sound playing function, and an LED light source is provided around the eye to emit the eye. The disclosed devices are basically eyecups containing sound playing devices, which can block the normal sight when in use, and the light source of the eyecups emits light towards human eyes, even emits light with specific frequency, so as to achieve the purpose of treatment.

As mentioned above, the light source of the conventional eye mask integrated with a light source in the prior art generally plays a role of emitting light outwards, and due to the fact that the eye mask shields human eyes, the problem that the user cannot watch the external environment during use is solved, and the effect of a sound player is not achieved. And the emergent light of other devices integrating the light source and the sound player is emitted to the eyeball, so that the special effect of stimulating the brain is achieved, and the effect of phototherapy on the skin of a human body cannot be realized. Therefore, the development of an integrated and portable phototherapy device which can perform phototherapy on the skin of a human body and listen to audio without influencing normal sight has wide market prospect and application value.

A typical single layer OLED device is shown in figure 1 a. The OLED device 100 includes, among other things, 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. 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. The hole injection layer 102 may be a single layer of material, such as the commonly used 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 comprise multiple light emitting layers, and OLED device 110 as shown in fig. 1b may comprise a red light emitting layer 105a and a deep red light emitting layer 105b. The red light emitting layer 105a can be implemented by doping a red light host material with a red light emitting material; similarly, the deep red light emitting layer 105b can 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 region and realize color change caused by the drift of the light-emitting region under different electric driving. For example, at low current densities OLEDs may emit predominantly red light, stimulating collagen regeneration, and at high current densities OLEDs may emit deep red or even near infrared light, serving the moisturizing effect. Of course, a single-layer device having three light-emitting layers, such as a red light layer, a deep red light layer, and a near-infrared light-emitting layer, can also be prepared on the basis of the OLED device 110. 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 can also be implemented in a stacked structure, and a structural diagram of a stacked OLED device 200 is shown in fig. 1c, for example, and 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 by a charge generation layer 111, and an anode 101 and a cathode 109 are respectively disposed at the bottom and the top of the stacked OLED device 200. The charge generation layer 111 may further include an n-type material layer and a p-type material layer to conduct electrons and holes, respectively. The charge generation layer may further include a buffer layer material, and reference may be made to patent application CN112687811a, which is not the content of the important research in this application and is not described herein again. The stacked OLED device shown in fig. 1c is a dual-cell structure, where the

light emitting cells

201 and 202 can be two red light emitting cells, and the stacked device is advantageous for improving current efficiency and device lifetime, and is generally a structure commonly used in OLED lighting. Similarly, three red light emitting cells can also be stacked, as shown in the three-layer stacked OLED device 210 in fig. 1d, which comprises a first light emitting cell 201, a second light emitting cell 202 and a third light emitting cell 203, connected with charge generation layers 111 and 121 between them, with an anode 101 and a cathode 109 disposed across the device. Of course, the light emitting units can emit light with different colors, such as a first light emitting unit emitting red light with a wavelength between 600 nm and 640nm, a second light emitting unit emitting red light with a wavelength between 640nm and 700nm, and a third light emitting unit emitting near infrared light with a wavelength above 700 nm. Techniques for using stacked device structures are well known to those skilled in the art and will not be described in detail herein.

A cross-sectional view of an OLED light-emitting panel is shown in figures 3a-3d on the basis of the above-described device. In fig. 3a, 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, an encapsulating layer 302 exposing the contact electrodes 303, and a bonding 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, etc. In particular, the substrate 301 may be a material (e.g., polyimide 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 base plate by using a laser and is transferred to other flexible substrates according to requirements. 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 luminous efficiency. OLED device 310 can be a single layer structure or a stacked layer structure, with a stacked layer structure being preferred because it has a longer lifetime at the same brightness and because a thicker film layer is beneficial for increasing production yield. The organic materials 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 encapsulation layer 302 may be glass adhered to the device by UV curable adhesive, preferably a thin film encapsulation layer, generally having a thickness of 10 μm or more, such as a single inorganic layer, or a thin film organic-inorganic alternating multilayer structure, formed by PECVD, ALD, printing, spin coating, etc. If both the substrate 301 and the encapsulation layer 302 are flexible, 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 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 using an FPC board to drive an OLED light emitting panel can be found in chinese patent application CN110299349a, 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 various forms. Such an OLED light-emitting panel is one of the basic components of the OLED light source in the present invention.

Light in a plurality of different wavelength bands can be generated on one OLED light-emitting panel in several 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 millimetres, i.e. a minimum dimension greater than 1mm, preferably greater than 5mm. For example, an OLED light-emitting panel 500 shown in fig. 5a may include an 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 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. Different OLED devices are controlled through external electric drive, so that different devices can emit light with different colors, or the same device works under different currents, and multiple colors are realized. A variation of this is an OLED light emitting panel 510 as shown in fig. 5b comprising an OLED substrate 501, a series of OLED devices 502, but each device enjoys a separate encapsulating layer 513, and preferably 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 implement the colour change by means of the movement of the recombination zones at different operating points, using the same structure of independent unit multiple light-emitting layers, as described in patent applications CN111081892A and CN111081891 a. The OLED substrate 501 in both of the above schemes may be rigid or flexible, preferably flexible. 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 non-flexible OLED panels and/or non-flexible encapsulation layers can be used, provided that the area is small enough that the light source formed into the array still has some flexibility, but preferably each individual OLED panel is also 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 may be arranged and combined through an FPC or front and rear cover films, etc. as required to form a lattice that is physically connected to each other, and reference may be made to the method disclosed in CN208750423U specifically, which is not the focus of the research in this application and is not described again. Also, the panels may be independently controlled to apply different operating currents. The array arrangement can realize multicolor luminescence and partition control, and the phototherapy device can respectively start light with different wave bands for different parts or only carry out illumination treatment for specific parts by using the array arrangement, so that energy consumption is reduced.

Fig. 4a is a schematic structural diagram of a phototherapy apparatus 400 according to the present invention, and as shown in fig. 4a, the phototherapy apparatus 400 includes a housing 410, a driving device 420, a light source 430 and a sound player 440. The housing 410 includes an outer shell 411, an inner shell 412, and a fixing structure 413.
