Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of photobiomodulation, and in particular to a light therapy device. Background Art

[0002] In the current medical device field, devices that use light to treat certain diseases have emerged. Those skilled in the art refer to this as phototherapy, a method that uses visible and invisible light from sunlight and artificial light sources to prevent and treat diseases and promote recovery.

[0003] At present, most of the phototherapy products on the market use point light sources such as LED (Light-Emitting Diode) as light sources, but the luminous area of ​​point light sources is limited, and the energy utilization and uniformity are not ideal. In actual use, multiple point light sources need to be arranged to achieve a larger irradiation area. In addition, the light intensity in the area directly in front of each point light source is strong, and the light intensity in the area between two adjacent point light sources is weak. This inevitably causes the light of the phototherapy products using the point light source as the light source to be uneven, and even to have dark areas, thereby affecting the phototherapy effect. On the other hand, phototherapy products use surface light sources such as OLED (Organic Light Emitting Diode) as light sources. Surface light sources can emit light uniformly, but surface light sources are subject to the energy gap law, that is, as the energy gap difference between the excited state and the ground state decreases, the non-radiative transition rate constant increases exponentially, resulting in low luminous efficiency of the surface light source in the near-infrared light band. The development of high-efficiency organic near-infrared light-emitting elements has always been a huge challenge, and it has also severely restricted the development of phototherapy products using the surface light source as the light source.

[0039] Figure 1 This is a schematic diagram of the structure of a phototherapy device provided by an embodiment of the present invention. Figure 1 As shown, the phototherapy device includes a surface light source module 10 and a point light source module 20; the surface light source module 10 emits a first light beam, and the point light source module 20 emits a second light beam; at least part of the propagation path of the first light beam coincides with at least part of the propagation path of the second light beam, and on the overlapping propagation path of the first light beam and the second light beam, the first light beam and the second light beam merge to form a superimposed synthetic light beam.

[0040] Specifically, the phototherapy device includes a surface light source module 10 and a point light source module 20. Among them, the surface light source module 10 can emit light uniformly, but limited by the energy gap law, the surface light source module 10 has the problem of low luminous efficiency in the near-infrared band. The point light source module 20 can emit light in any band, but limited by the arrangement of the light sources, the point light source module 20 has the problem of limited luminous area and uneven illumination. Therefore, this embodiment combines the surface light source module 10 and the point light source module 20 to emit light, so that the luminous effects of the surface light source module 10 and the point light source module 20 compensate for each other, that is, the surface light source module 10 can improve the unevenness of the illumination of the point light source module 20, and the point light source module 20 can make up for the defect of low luminous efficiency in the near-infrared light band of the surface light source module 10. The light beam obtained by superimposing the two has the characteristics of suitable irradiation band, irradiation intensity and irradiation amount, and uniform irradiation.

[0041] The surface light source module 10 emits a first light beam, and the point light source module 20 emits a second light beam. At least part of the propagation path of the first light beam emitted by the surface light source module 10 overlaps with at least part of the propagation path of the second light beam emitted by the point light source module 20. In this way, on the propagation path where the first light beam emitted by the surface light source module 10 and the second light beam emitted by the point light source module 20 overlap, the first light beam and the second light beam can be merged into one beam, that is, a superimposed composite light beam is formed. It can be understood that the superimposed composite light beam formed by the first light beam and the second light beam merging together has the characteristics of suitable irradiation band, irradiation intensity and irradiation amount, and irradiation uniformity. In addition, there are also unmerged first light beams that propagate separately and unmerged second light beams that propagate separately. In addition, illustratively, the propagation path of the first light beam emitted by the surface light source module 10 can be adjusted by an optical element such as a reflector / semi-transparent mirror, and the propagation path of the second light beam emitted by the point light source module 20 can also be adjusted by an optical element such as a reflector / semi-transparent mirror, so that at least part of the propagation path of the first light beam emitted by the surface light source module 10 overlaps with at least part of the propagation path of the second light beam emitted by the point light source module 20. Alternatively, the point light source module 20 can be located on the propagation path of the first light beam emitted by the surface light source module 10, the first light beam emitted by the surface light source module 10 and the second light beam emitted by the point light source module 20 merge at the light-exiting side of the point light source module 20, and at least a portion of the propagation path of the first light beam emitted by the surface light source module 10 coincides with the propagation path of the second light beam emitted by the point light source module 20. Alternatively, the surface light source module 10 can be located on the propagation path of the second light beam emitted by the point light source module 20, the first light beam emitted by the surface light source module 10 and the second light beam emitted by the point light source module 20 merge at the light-exiting side of the surface light source module 10, and at least a portion of the propagation path of the second light beam emitted by the point light source module 20 coincides with the propagation path of the first light beam emitted by the surface light source module 10.

[0042] The superimposed synthetic light beam is the product of the combined superposition of the first light beam emitted by the surface light source module 10 and the second light beam emitted by the point light source module 20. The superimposed synthetic light beam has both the advantages of the first light beam emitted by the surface light source module 10 (for example, uniform light emission) and the advantages of the second light beam emitted by the point light source module 20 (for example, higher light emission efficiency in the near-infrared band). In this way, the superimposed synthetic light beam is used to stimulate the cells or tissues of the organism and thus change its physiological functions, thereby achieving a phototherapy effect of preventing and treating diseases and promoting the recovery of the body. In addition, it should be noted that the advantages of the first light beam emitted by the surface light source module 10 are only examples here and are not limited. The advantages of the second light beam emitted by the point light source module 20 are only examples here and are not limited. Other advantages are within the scope of protection of this embodiment. The superimposed synthetic light beam has all the advantages of the first light beam and the second light beam.

[0043] The superimposed composite light beam can be applied to the phototherapy process of the target treatment area. The phototherapy irradiation of the superimposed composite light beam at the target treatment area is uniformly distributed. The luminous efficiency of the superimposed composite light beam in the near-infrared light band meets the phototherapy irradiation requirements. The luminous efficiency of the superimposed composite light beam in the effective irradiation band also meets the phototherapy irradiation requirements. In a specific embodiment, the emission spectrum of the surface light source module 10 and the emission spectrum of the point light source module 20 can be determined according to the treatment site and treatment purpose during the phototherapy process. The emission spectrum of the surface light source module 10 and the emission spectrum of the point light source module 20 can be optimized and adjusted as the treatment site and treatment purpose change during the phototherapy process, so that the superimposed spectrum of the emission spectrum of the surface light source module 10 and the emission spectrum of the point light source module 20 at the target treatment area is required for the phototherapy process. In another specific embodiment, the irradiation intensity of the surface light source module 10 and the irradiation intensity of the point light source module 20 can be determined according to the treatment site, treatment purpose and treatment time during the phototherapy process. The irradiation intensity of the surface light source module 10 and the irradiation intensity of the point light source module 20 can be optimized and adjusted as the treatment site, treatment purpose and treatment time change during the phototherapy process, so that the superimposed irradiation intensity of the irradiation intensity of the surface light source module 10 and the irradiation intensity of the point light source module 20 at the target treatment area is what is required for the phototherapy process. For example, the irradiation intensity of the spectrum of different wavelength bands of the surface light source module 10 can be achieved by adjusting the light intensity corresponding to the wavelength band, and the irradiation intensity of the spectrum of different wavelength bands of the point light source module 20 can also be achieved by adjusting the light intensity corresponding to the wavelength band. In addition, after a certain phototherapy treatment time, the superimposed synthetic light beam required for the phototherapy process, within the effective irradiation wavelength band, within the sufficient irradiation energy range, and irradiated uniformly and flexibly after the surface light source module 10 and the point light source module 20 are superimposed can be irradiated to the target treatment area to achieve better treatment and rehabilitation effects. It can be understood that the emission spectra of the surface light source module 10 and the point light source module 20 can be the same or different, and the irradiation intensities of the surface light source module 10 and the point light source module 20 can be the same or different. Finally, the superimposed composite light beam formed by superimposing the first light beam emitted by the surface light source module 10 and the second light beam emitted by the point light source module 20 has an emission spectrum, irradiation intensity and irradiation amount at the target treatment area that are required for the phototherapy process. For example, according to the requirements of the phototherapy process, the first light beam emitted by the surface light source module 10 can be a red light beam, and the second light beam emitted by the point light source module 20 can be a near-infrared light beam. The superimposed composite light beam obtained by superposition can have the phototherapy effects of both the red light beam and the near-infrared light beam, and can be used for treatment processes such as fat reduction, skin regeneration, scar removal and wrinkle removal.

[0044] According to the technical solution in the embodiment of the present invention, the phototherapy device includes a surface light source module and a point light source module; the surface light source module emits a first light beam, and the point light source module emits a second light beam; at least part of the propagation path of the first light beam coincides with at least part of the propagation path of the second light beam, and on the propagation path where the first light beam and the second light beam coincide, the first light beam and the second light beam merge to form a superimposed synthetic light beam. The phototherapy device combines and superimposes the light beams emitted by the surface light source module and the point light source module. The surface light source module can improve the unevenness of the illumination of the point light source module, and the point light source module can make up for the defect of low luminous efficiency in the near-infrared light band of the surface light source module. In this way, the phototherapy device can not only ensure the uniformity of phototherapy irradiation in the target treatment area, but also make up for the defect of low luminous efficiency in the near-infrared light band of the surface light source module, realize the optimal spectral wavelength distribution in the target treatment area, and ensure that the irradiation beam is uniformly irradiated within the effective irradiation band and within the sufficient irradiation energy range. At the same time, the surface light source module or the point light source module is flexibly attached to the target treatment area, ensuring that the superimposed synthetic light beam is uniformly and effectively irradiated to the target treatment area, thereby achieving better treatment and rehabilitation effects.

[0045] In a specific embodiment, optionally, continue to refer to Figure 1 and Figure 2 The point light source module 20 includes at least one of a light emitting diode (LED), a micro-LED, a mini-LED, or a sub-millimeter light emitting diode (LED). The surface light source module 10 includes at least one of an organic light emitting diode (OLED), a quantum dot light emitting diode (QLED), or a perovskite light emitting diode (PeLED).

[0046] Optionally, continue to refer to Figure 1 The surface light source module 10 is located on the propagation path of the second light beam emitted by the point light source module 20. The surface light source module 10 transmits at least a portion of the second light beam. In the propagation path where the transmitted at least portion of the second light beam overlaps with the first light beam emitted by the surface light source module 10, the first light beam and the second light beam merge to form a superimposed composite light beam. Furthermore, the transmittance of the surface light source module 10 is greater than 80%.

[0047] Specifically, the surface light source module 10 can be located on the propagation path of the second light beam emitted by the point light source module 20, so that the first light beam emitted by the surface light source module 10 and the second light beam emitted by the point light source module 20 converge on the light-emitting side of the surface light source module 10, and at least part of the propagation path of the second light beam emitted by the point light source module 20 coincides with the propagation path of the first light beam emitted by the surface light source module 10. That is, the distance between the surface light source module 10 and the target treatment area is smaller than the distance between the point light source module 20 and the target treatment area. Exemplarily, the distance between the surface light source module 10 and the point light source module 20 can be determined according to the space of the phototherapy device and the irradiation intensity required for phototherapy. This embodiment only illustrates the structure in which the surface light source module 10 and the point light source module 20 are arranged side by side, and is not limited thereto. In addition, the surface light source module 10 can transmit at least part of the second light beam, and on the propagation path where the transmitted at least part of the second light beam coincides with the first light beam emitted by the surface light source module 10, the first light beam and the second light beam converge into one beam, that is, forming the superimposed synthetic light beam. For example, the propagation direction of the second light beam emitted by the point light source module 20 may be perpendicular to the plane where the target treatment area is located, and the first light beam emitted by the surface light source module 10 may be evenly distributed within the plane where the target treatment area is located.

[0048] It is understandable that, in the process of combining the first light beam emitted by the surface light source module 10 and the second light beam emitted by the point light source module 20, in order to reduce the energy loss of the second light beam emitted by the point light source module 20 during the propagation process, especially the loss during the process of passing through the surface light source module 10, the transmittance of the surface light source module 10 can be set to be greater than 80%, that is, the greater the proportion of the second light beam that can pass through the surface light source module 10, the better. Exemplarily, a transparent light-emitting device can be used in the surface light source module 10, and the substrate, electrode material, packaging material, etc. of the light-emitting device can all be made of transparent materials. Exemplarily, the substrate of the light-emitting device can be made of flexible transparent plastic, and the substrate of the light-emitting device can be made of transparent glass, polyester (PET), polyimide (PI), polycarbonate (PC), polyetheretherketone (PEEK) and other transparent materials.

[0049] Optionally, Figure 2 This is a schematic diagram of the structure of another phototherapy device provided by an embodiment of the present invention. Figure 2 As shown, point light source module 20 is located along the propagation path of the first light beam emitted by surface light source module 10. Point light source module 20 transmits at least a portion of the first light beam. At the point where the transmitted at least portion of the first light beam overlaps with the second light beam emitted by point light source module 20, the first and second light beams merge to form a superimposed composite light beam. Furthermore, point light source module 20 has a light transmittance greater than 80%.

[0050] Specifically, the point light source module 20 can be located on the propagation path of the first light beam emitted by the surface light source module 10, so that the first light beam emitted by the surface light source module 10 and the second light beam emitted by the point light source module 20 converge at the light-emitting side of the point light source module 20, and at least part of the propagation path of the first light beam emitted by the surface light source module 10 coincides with the propagation path of the second light beam emitted by the point light source module 20. That is, the distance between the point light source module 20 and the target treatment area is smaller than the distance between the surface light source module 10 and the target treatment area. Exemplarily, the distance between the surface light source module 10 and the point light source module 20 can be determined according to the space of the phototherapy device and the irradiation intensity required for phototherapy. This embodiment only illustrates the structure in which the surface light source module 10 and the point light source module 20 are arranged side by side, and is not limited thereto. In addition, the point light source module 20 can transmit at least part of the first light beam, and on the propagation path where the transmitted at least part of the first light beam coincides with the second light beam emitted by the point light source module 20, the first light beam and the second light beam converge into one beam, that is, forming the superimposed synthetic light beam. For example, the propagation direction of the second light beam emitted by the point light source module 20 may be perpendicular to the plane where the target treatment area is located, and the first light beam emitted by the surface light source module 10 may be evenly distributed within the plane where the target treatment area is located.

[0051] It is understandable that, in the process of combining the first light beam emitted by the surface light source module 10 and the second light beam emitted by the point light source module 20, in order to reduce the energy loss of the first light beam emitted by the surface light source module 10 during the propagation process, especially the loss during the process of passing through the point light source module 20, the transmittance of the point light source module 20 can be set to be greater than 80%. That is, the greater the proportion of the first light beam that can pass through the point light source module 20, the better. Exemplarily, a transparent light-emitting device can be used in the point light source module 20, and the substrate, electrode material, packaging material, etc. of the light-emitting device can all be made of transparent materials. Exemplarily, the substrate and packaging material of the light-emitting device can be made of flexible transparent plastic, and the substrate and packaging material of the light-emitting device can be made of transparent materials such as polyester (PET), polyimide (PI), polycarbonate (PC), polyetheretherketone (PEEK), silicone, etc.

[0052] Optionally, Figure 3-Figure 6 Schematic diagrams of the structures of four phototherapy devices provided by the embodiments of the present invention are shown in FIG. Figure 3-Figure 6 As shown, the surface light source module 10 includes at least one surface light source unit 11; each surface light source unit 11 is arranged according to a first preset path; and / or, the point light source module 20 includes at least one point light source unit 21; each point light source unit 21 is arranged according to a second preset path; wherein, the number of surface light source units 11 is the same as or different from the number of point light source units 21, and the first preset path is the same as or different from the second preset path.

[0053] Specifically, Figure 3The surface light source module 10 shown includes three surface light source units 11, each of which is arranged according to a first preset path. By way of example, this embodiment does not limit the first preset path, which can be determined based on the conditions of the treatment site. This embodiment only exemplifies the structure in which the three surface light source units 11 are arranged at intervals in the cross-sectional view. The point light source module 20 includes a point light source unit 21, and the three surface light source units 11 are all on the propagation path of the second light beam emitted by the point light source unit 21. Figure 4 The point light source module 20 shown includes three point light source units 21, each of which is arranged according to a second preset path. By way of example, this embodiment does not limit the second preset path, which can be determined based on the conditions of the treatment site. This embodiment only exemplifies the structure in which the three point light source units 21 are arranged at intervals in the cross-sectional view. The surface light source module 10 includes a surface light source unit 11, and the surface light source unit 11 is simultaneously located on the propagation path of the second light beams emitted by the three point light source units 21. Figure 5 The point light source module 20 shown includes three point light source units 21, each of which is arranged according to a second preset path. By way of example, this embodiment does not limit the second preset path, which can be determined based on the conditions of the treatment site. This embodiment only exemplifies the structure in which the three point light source units 21 are arranged at intervals in the cross-sectional view. The surface light source module 10 includes a surface light source unit 11, and the three point light source units 21 are all on the propagation path of the first light beam emitted by the surface light source unit 11. Figure 6 The surface light source module 10 shown includes three surface light source units 11, and each surface light source unit 11 is arranged according to a first preset path. For example, this embodiment does not limit the first preset path. The first preset path can be determined according to the situation of the treatment site. This embodiment only exemplifies the structure in which the three surface light source units 11 are arranged at intervals in the cross-sectional view. The point light source module 20 includes a point light source unit 21, and the point light source unit 21 is simultaneously located on the propagation path of the first light beam emitted by the three surface light source units 11.

[0054] It should be noted that Figure 3-Figure 6 The structure of the phototherapy device shown is for illustration only and is not limited here. The number of surface light source units 11 in the surface light source module 10 may be other, the number of point light source units 21 in the point light source module 20 may be other, the position setting of the surface light source unit 11 may be other, and the position setting of the point light source unit 21 may be other.

[0055] Further, Figure 7 This is a structural diagram of another phototherapy device provided by an embodiment of the present invention. Figure 7As shown, the surface light source module 10 includes at least two surface light source units 11, and the point light source module 20 includes at least two point light source units 21. The number of surface light source units 11 is the same as the number of point light source units 21 and is arranged accordingly; some of the surface light source units 11 are located on the propagation path of the second light beam emitted by the point light source unit 21, and another part of the point light source units 21 are located on the propagation path of the first light beam emitted by the surface light source unit 11.

[0056] Specifically, Figure 7 The surface light source module 10 shown includes three surface light source units 11, and the point light source module 20 includes three point light source units 21. A surface light source unit 11 and a point light source unit 21 can be defined as a group of sub-light sources. In any group of sub-light sources, the surface light source unit 11 can be located on the propagation path of the second light beam emitted by the point light source unit 21, or the point light source unit 21 can also be located on the propagation path of the first light beam emitted by the surface light source unit 11. That is, Figure 7 The two point light source units 21 are respectively located on the propagation paths of the first light beams emitted by the corresponding surface light source units 11. Figure 7 The surface light source unit 11 shown is located on the propagation path of the second light beam emitted by the point light source unit 21 corresponding to it. For example, in the target treatment area, the near-infrared band of the spectrum in the treatment spectrum of the light therapy required in some areas accounts for a higher proportion, then the area is more suitable for setting the point light source unit 21 on the propagation path of the first light beam emitted by the surface light source unit 11 corresponding to it, that is, the distance between the point light source unit 21 and the area is less than the distance between the corresponding surface light source unit 11 and the area, that is, the point light source unit 21 is closer to the area, effectively improving the treatment efficiency. And, if the red light band of the spectrum in the treatment spectrum of the light therapy required in another part of the area accounts for a higher proportion, then the surface light source unit 11 is more suitable for setting the surface light source unit 11 on the propagation path of the second light beam emitted by the point light source unit 21 corresponding to it, that is, the distance between the surface light source unit 11 and the area is less than the distance between the corresponding point light source unit 21 and the area, that is, the surface light source unit 11 is closer to the area, effectively improving the uniformity of the light beam.

[0057] It should be noted that Figure 7 The structure of the phototherapy device shown is for illustration only and is not limited here. The number of surface light source units 11 in the surface light source module 10 may be other, the number of point light source units 21 in the point light source module 20 may be other, the position setting of the surface light source units 11 may be other, the position setting of the point light source units 21 may be other, the surface light source units 11 arranged one by one may be located on the propagation path of the second light beam emitted by the point light source units 21, or the point light source units 21 arranged one by one may also be located on the propagation path of the first light beam emitted by the surface light source unit 11.

[0058] Optionally, Figures 8-10 This is a schematic diagram of the structure of three point light source modules provided by the embodiment of the present utility model. Figures 8-10 As shown, the point light source module 20 includes a plurality of point light sources 22 ; each point light source 22 is arranged according to a third preset path.

[0059] Specifically, each point light source 22 in the point light source module 20 is arranged according to a third preset path. Exemplarily, the point light source module 20 may include a point light source unit 21, and then each point light source 22 in the point light source unit 21 is arranged according to the third preset path, or, the point light source module 20 may include multiple point light source units 21, and then the number of point light sources 22 in each point light source unit 21 is the same or different, and the arrangement of the third preset path corresponding to the point light sources 22 in each point light source unit 21 is the same or different. This embodiment does not limit the number of point light source units 21, but only represents the arrangement of multiple point light sources 22 in any point light source unit 21. It can be understood that the arrangement rules of each point light source 22 in the point light source module 20 can be determined according to the distance between the point light source module 20 and the target treatment area, the shape of the treatment area, and the form of the treatment device, and the distance between two adjacent point light sources 22 can be determined according to the radiation intensity of the point light source 22, so as to avoid the appearance of a dark area in the target treatment area corresponding to the area between the two adjacent point light sources 22. Exemplarily, the projections of the point light sources 22 in the point light source module 20 on the first plane are evenly arranged. Exemplarily, Figure 8 The third preset path shown may be an array arrangement, and the shape of the first plane where the corresponding point light sources 22 are arranged may be a rectangle. Figure 9 The third preset path shown may be the ecological pattern of a butterfly wing, and the shape of the first plane where the corresponding point light sources 22 are arranged may be an ellipse. Figure 10 The third preset path shown can be a circular arrangement, and the shape of the first plane where the corresponding point light sources 22 are arranged can be circular. In addition, the third preset path can also be a technological circuit pattern, etc., and the shape of the first plane where the corresponding point light sources 22 are arranged can change accordingly.

[0060] Optionally, continue to refer to Figure 1 and Figure 2 The phototherapy device also includes a skin-friendly module 30 and an appearance module 40; the skin-friendly module 30 is located on the propagation path of the superimposed synthetic light beam; the transmittance of the skin-friendly module 30 is greater than 80%; the appearance module 40 is located on the side away from the light-emitting surface of the surface light source module 10; and / or, the appearance module 40 is located on the side away from the light-emitting surface of the point light source module 20.

[0061] Specifically, the skin-friendly module 30 is located on the propagation path of the superimposed composite light beam, so that the distance between the skin-friendly module 30 and the target treatment area is smaller than the distance between the surface light source module 10 and the target treatment area; and / or the distance between the skin-friendly module 30 and the target treatment area is smaller than the distance between the point light source module 20 and the target treatment area. The skin-friendly module 30 is close to the treatment site, or the skin-friendly module 30 can directly contact the treatment site. The skin-friendly module 30 can be made of a soft, skin-friendly material with high light transmittance to minimize the energy loss of the superimposed composite light beam obtained by superposition during the propagation process and to improve the user experience. Exemplarily, the light transmittance of the skin-friendly module 30 is greater than 80%. Exemplarily, the skin-friendly module 30 can be made of transparent materials such as transparent plastic and silicone. In addition, the skin-friendly module 30 can also play a sealing role to prevent the surface light source module 10 and the point light source module 20 inside the phototherapy device from being contaminated by external impurities, thereby affecting the phototherapy effect. For example, the skin-friendly module 30 may include an irradiation window, through which the superimposed composite light beams are emitted to the target treatment area. For example, the irradiation window may be larger than 200 mm x 200 mm. An irradiation window of this size allows most skin disease patients to complete large-area treatment with a single irradiation, saving time for patients and effectively improving treatment efficiency.

[0062] Specifically, the appearance module 40 is located on the side away from the light-emitting surface of the surface light source module 10. In this way, the appearance module 40 can play the role of encapsulating the surface light source module 10, preventing the surface light source module 10 from being contaminated by external impurities, etc., thereby affecting the phototherapy effect, and will not affect the normal light emission of the surface light source module 10. And / or, the appearance module 40 is located on the side away from the light-emitting surface of the point light source module 20. In this way, the appearance module 40 can play the role of encapsulating the point light source module 20, preventing the point light source module 20 from being contaminated by external impurities, etc., thereby affecting the phototherapy effect, and will not affect the normal light emission of the point light source module 20. Exemplarily, the appearance module 40 can use an encapsulation material. In addition, the appearance module 40 can also play a reflective role to change the propagation direction of the first light beam emitted by the surface light source module 10, and change the propagation direction of the second light beam emitted by the point light source module 20. The first light beam and / or the second light beam incident on the appearance module 40 can be reflected so that more of the first light beam and / or the second light beam are incident on the target treatment area, effectively reducing light loss. Exemplarily, the reflectivity of the appearance module 40 is greater than 80%. Exemplarily, the appearance module 40 may be made of reflective materials such as reflective film and luminescent coating. Of course, the material selection for the appearance module 40 can also be adjusted based on the specific requirements of the phototherapy product. Exemplarily, in phototherapy products such as phototherapy eye patches and phototherapy facial masks, the appearance module 40 may be made of transparent materials such as transparent plastic. This embodiment is merely an example and is not intended to be limiting. The appearance module 40 may also be made of other materials.

[0063] In addition, it should be noted that the phototherapy device provided by the embodiment of the present invention can be applied to the field of photobiomodulation, and the phototherapy device includes but is not limited to wearable devices (such as phototherapy patches, phototherapy films, phototherapy eye patches, phototherapy masks, phototherapy caps, phototherapy socks, etc.) and non-wearable devices (such as phototherapy beds, phototherapy lamps, etc.). Exemplarily, when the phototherapy device is applied to phototherapy eye patches, the phototherapy eye patches include an upper packaging cover (equivalent to the appearance module of the present application) and a lower packaging cover (equivalent to the skin-friendly module of the present application), and the surface light source module and the point light source module are arranged in the area sealed by the upper packaging cover and the lower packaging cover. Exemplarily, when the phototherapy device is applied to a phototherapy mask, the phototherapy mask includes an outer cover (equivalent to the appearance module of the present application) and a transparent layer (equivalent to the skin-friendly module of the present application), and the surface light source module and the point light source module are arranged in the area sealed by the outer cover and the transparent layer. For example, when the phototherapy device is used as a phototherapy hand mask, the phototherapy hand mask includes a housing (equivalent to the appearance module of this application) and a light-transmitting portion (equivalent to the skin-friendly module of this application), and the surface light source module and the point light source module are disposed in the area sealed between the housing and the light-transmitting portion. This embodiment will not be further illustrated here.
