[0042] A technical solution of preferred embodiments according to the present invention is further described below with reference to the accompanying drawings and through preferred, nonlimiting, implementation methods .

[0043] As shown in Figures 1 to 9 , a speci fic embodiment of the present invention discloses a phototherapy mask, including a mask body 120 , comprising a plurality of lamp beads 100 . A plurality of protruding members 210 are disposed on one side of the lamp beads 100 for providing a predetermined distance , or increasing, the distance between the lamp beads 100 and a human face . Alternatively, a distance between light guides is extended by increasing the distance to the human face , providing conditions for implementing scattered light or focused light , thereby improving the phototherapy ef fect .

[0044] Preferably, the protrusion 210 is a light-transmit- ting structure . The light-transmitting structure provides support and provides the light-guiding spacing without affecting the normal transmission of light from the lamp beads , thereby achieving a predetermined and / or desired phototherapy ef fect .

[0045] Furthermore , the position of a protrusion 210 corresponds to a respective lamp bead 100 , and the protrusion corresponding to the lamp bead may advantageously guide light and provide the basic conditions for focusing or di ffusing light .

[0046] Further preferably, the protrusion 210 is a lens structure , and the si ze of the irradiated light spot on the face or the skin thereof may be defined on the basis of determining spacing of the light guide . Several light guide ef fects may be achieved according to the shape of the protrusion to meet preferred needs .

[0047] For example , when the protrusion is a convex lens structure , it may achieve an ef fective light focusing effect , which is used to achieve the ef fect of local higher intensity irradiation phototherapy .

[0048] With this , the phototherapy ef fect on the sides of the nose and the corners of the eyes are preferably achieved .

[0049] When the protrusion is a concave lens structure , it may achieve a diverging ef fect or otherwise an astigmatism ef fect , and the light spots overlap with each other, preventing an area to be missed and / or achieving a more comprehensive coverage . With this , an ef fective the phototherapy ef fect is advantageously achieved .

[0050] Alternatively, when both end surfaces of the protrusion are planar structures , the protrusion itsel f does not have the ef fect of diverging, astigmatism or focusing, and only has the ef fect of increasing the spacing . According to a law of light irradiation, a larger light spot may also be formed on the face , which has a similar ef fect to when the protrusion is a concave lens structure , reducing the missing area, expanding the irradiation coverage , and improving the phototherapy ef fect . Alternatively, when the protrusion plays the function of astigmatism, there is no need to expand the light spot coverage by densely arranging lamp beads , which means that the use of lamp beads may be reduced, and the production cost of the mask may be reduced .

[0051] It is mentioned that based on structures of the above-mentioned several lenses , and according to the illumination requirements of the actual layout , the lens type and structure are preferably predetermined so that the illumination angle formed by the light transmitting through the protrusions of the lamp beads is between 10 ° and 170 ° , thereby achieving targeted enhancement of the focus- ing / scattering coverage according to di f ferent parts , and adj usting the design to better adapt to the human face to ensure the phototherapy ef fect .

[0052] Further preferably, a groove is provided on the side of the protruding member 210 close to the lamp bead 100 , and the wall surface of the groove away from the lamp bead is an arc surface . The design of the groove may provide a receiving position, which may facilitate the protruding member cover to be arranged on the outside of the lamp bead, so that the overall structure may be more compact and prevent the protruding member from directly contacting the lamp bead .

[0053] Furthermore , it is mentioned that , on this basis , i f the protruding member is preferred to have a focusing effect , as shown in Figure A in Figure 1 , the depth of the groove is preferably reduced, and the wall surface of the protruding member away from the lamp bead is in an arc shape , or at least the edge portion needs to be cut , so that the protruding member as a whole provides an ef fect of being thick in the middle and thin on both sides , maintaining the structure of the convex lens and achieving the focusing ef fect ;

[0054] I f the raised part is preferred to have a di f fuse light ef fect , as shown in Figure 1 B, the wall away from the lamp bead includes but is not limited to a flat struc- ture / arc surface , but it is preferably provided that the raised part as a whole has a thin middle and thick edge structure , maintain the structure of the concave lens , and thereby achieve the di f fuse light ef fect .

[0055] Further preferably, the facemask includes a face contact member 200 , a protruding member 210 is arranged on the face contact member 200 , and the face contact member 200 is installed on the mask body 100 . The mask body includes a cover member 300 and a flexible circuit board 400 . The flexible circuit board is closely arranged on the cover member . The lamp bead 100 is protruded and arranged on the wall of the flexible circuit board 400 away from the cover member 300 . The edge of the face contact member 200 is closely arranged on the cover member 300 , and is detachably fastened by means of snap connection, bonding or magnetic connection, the face contact member is covered on the flexible circuit board, and the light of the lamp bead penetrates the face contact member to irradiate outward .

[0056] Furthermore , as a device for mask use , considering the layout and compactness of the overall structure , the lamp bead used is a flat and thin lamp bead body, preferably an LED lamp bead . S ide wings extending outward are provided on both sides of the cover member , and Velcro is provided at the end of the side wings , and the two side wings are connected by Velcro to achieve a wearing ef fect about the head of the face , thereby forming a complete light therapy mask structure for actual application . Other common structural components such as electrical components and remote control components and circuit connection methods are not described in detail .

[0057] First preferred embodiment .

[0058] In a first preferred embodiment , the face contact member 200 includes a first panel 220 , and a protrusion 210 is disposed on the first panel 220 . The protrusion 210 protrudes outward in a direction away from the lamp bead 100 and protrudes out of the wall of the first panel 220 away from the mask body .

[0059] The face contact member preferably has a single-layer structure , which may ef fectively ensure the light transmittance , so that the light may be advantageously transmitted outward . By preferably setting a protrusion protruding in the direction away from the mask body, the ef fect of increasing the light guide spacing is achieved, and the required focusing or di f fusing ef fect is also achieved .

[0060] As shown in Fig . 2 and Fig . 3 , in scheme A of the present embodiment , the protrusion 210 and the first panel 220 are an integral structure . The protrusion and the first panel are an integral structure , which ensures the overall continuity and suf ficient structural strength, and the overall light transmittance is relatively uni form . I t is also convenient for processing and production, and the protrusion and the first panel are an integral structure and are manufactured by an integrated molding method, such as one-time casting molding, two-time casting molding, etc .

[0061] Since the protrusion and the first panel are the parts that contact the human face , they may be made of flexible material, preferably a silicone; and the design of the groove not only serves the purpose of accommodating the parts, but also increases the extrusion deformable spacing of the protrusion, achieving soft contact with the human face, thereby providing an advantageous contact.

[0062] As shown in FIG. 4 and FIG. 5, in the scheme B of the present embodiment, the first panel 220 is provided with a plurality of through holes 230 corresponding to the lamp beads 100, and the protrusions 210 are installed at the through holes 230. Compared with the scheme A of the embodiment 1, a similar single-layer structure may be used, and the light guide spacing may be increased by the protrusions protruding outward, and the desired focusing or diffusing effect may also be achieved;

[0063] A difference is that the assembled structure adopted in this embodiment may be matched by clamping or bonding, and protrusions with different light transmittances may be selected according to different bone parts or facial acupuncture points to meet different irradiation intensities;

[0064] In addition, protrusions of different strengths may be selected according to different parts to achieve a combination of local strong support and local soft support, so that the mask may fit the face better and more adaptably; because it is a dispersed and independent protrusion structure, even if a harder structure is used, it will prevent excessively damage the deformation effect of the entire face-contacting part, and a normal bending and use of the mask is achieved.

[0065] Second embodiment.

[0066] As shown in Fig. 6 and Fig. 7, in this embodiment, the face contact member 200 includes a first panel 220 and a second panel 240. The protrusion 210 is disposed on the first panel 220. The second panel 240 is disposed on the wall of the first panel 220 adj acent to the mask body, covering the lamp bead 100 .

[0067] Compared with the scheme A of the embodiment 1 , it is similar that the light guide spacing may be increased by the outwardly protruding protrusions , and the required light focusing or light di f fusion ef fect may be achieved; and the protrusions and the first panel are an integrated structure of silicone material ;

[0068] A di f ference is that in this embodiment , a second panel is used, and the second panel is also made of a flexible material , preferably a silicone material . The second panel is arranged between the lamp bead and the protruding member, which may further increase the light guide spacing to meet the required ef fect . S ince the flexible circuit board and the lamp bead are electrical components , the added second panel may enhance the insulation ef fect to a certain extent , play a protective role , and improve the safety of use .

[0069] With using the second panel , the protruding part will also have a corresponding ef fect . The design of the groove may increase the extrusion deformable spacing of the protruding part , and the light-guiding spacing may be shortened when it is deformed by contact with the human face . The addition of the second panel may compensate for the shortened light-guiding spacing caused by the deformation to a certain extent , making its overall ef fect better than the method of supporting only by the protruding part with a groove in scheme a of embodiment 1 . Furthermore , its overall structure is less compact as the scheme of embodiment 1 .

[0070] Third embodiment .

[0071] As shown in Fig . 8 and Fig . 9 , in this preferred embodiment , the face contact member 200 includes a first panel 220 and a second panel 240 . The protrusion 210 is disposed on the first panel 220 , and the second panel 240 is disposed on a side of the first panel 220 directed away from the mask body and covers the protrusion 210 .

[0072] Compared with the solution of the above second preferred embodiment , similar points are that the light guide spacing may be increased by the outwardly protruding protrusions , and the desired light focusing or light di f fusion ef fect may be achieved . The protrusions and the first panel are an integrated structure of silicone material . A second panel is also provided, and the second panel is also made of a flexible material , preferably silicone material , which may further increase the light guide spacing and / or to a certain extent compensate for the light guide spacing shortened by the deformation of the protrusions and provide an insulating protection ef fect .

[0073] A di f ference is that the second panel in this embodiment is arranged on the raised side of the raised member, so that the portion in contact with the face is in a flat state as a whole , instead of a situation where multiple raised points of the raised member contact the face , which may further improve the tactile experience , and the ef fect may be preferred in relation to that of the above embodiments .

[0074] Furthermore , the groove is close to the lamp bead and the cover is arranged outside the lamp bead . Compared with Example 2 , the light guide spacing reduces the thickness of the first panel , and the structure is more compact while meeting the illumination range .

[0075] It is mentioned that in the above-mentioned multiple embodiments , the first panel , the second panel , and the protrusion are preferably transparent structures or translucent structures to achieve the desired light-guiding ef fect . The light-guiding spacing range to be achieved is between 2 and 7 mm . The thickness of the panel or the protruding thickness of the protrusion is adj usted according to the combination of di f ferent embodiments . The above-mentioned light-guiding spacing range is achieved through coordinated cooperation to achieve the desired focusing and scattering ef fects .

[0076] Furthermore , it is preferred to adapt the si ze of the protruding members to a respective area of the face it is arranged at . Also the length of the protruding members is thereto adapted . In this sense , the length is the distance between the light bead and the distant limit of the protruding member . At a location of the face where there is a larger distance between light bead and the skin of the face , parameters of the protruding members are adapted, such parameters including the strength of the lens , whether the lens is to be diverging or converging . Also whether the distance between the light bead and the face is to be determined by physical contact between the facemask and the respective area of the skin determines for instance the length and / or other parameters of the respective protruding member .

[0077] The present invention is described in the foregoing on the basis of preferred embodiments . Di f ferent aspects of di f ferent embodiments are expressly considered disclosed in combination with each other and in all combinations that on the basis of this document , when read by a skilled person of the area of skill , fall within the scope of the invention or are deemed to be read with the disclosure of this document . These preferred embodiments are not limitative for the scope of protection of this document . The rights sought are defined in the appended claims .
