[0010] A preferred embodiment of the present invention will now be described.

[0011] Each light source of the optical cosmetic device of the present invention may have multiple light-emitting elements that emit visible light of different wavelengths. Visible light of different wavelengths has different effects on the irradiated skin. Therefore, by emitting visible light of different wavelengths toward the user's face, this optical cosmetic device can achieve different cosmetic effects depending on each wavelength.

[0012] The light source of the optical cosmetic device of the present invention may have a light-emitting element that emits invisible light of different wavelengths depending on the position on the mask. In this case, the optical cosmetic device can achieve a cosmetic effect appropriate for each part of the user's face by arranging the light sources that emit invisible light of wavelengths appropriate for each part of the face at positions corresponding to each part of the face.

[0013] The mask of the optical cosmetic device of the present invention may have a light source disposed opposite the forehead of the wearer, the light source having a light-emitting element that emits invisible light of a wavelength whose energy reaches the deep dermis. In this case, the optical cosmetic device delivers invisible light energy to the deep dermis of the wearer's forehead, increasing the thickness of the dermis, collagen fiber density, and fibroblast count, thereby achieving cosmetic effects such as repairing aged dermis, plumping the lower skin layer, and reducing wrinkles.

[0014] The mask of the optical cosmetic device of the present invention may be provided with a light source having a light-emitting element that emits invisible light of a wavelength whose energy reaches the subcutaneous tissue, positioned opposite the area around the nasolabial folds of the user when the mask is worn. In this case, the invisible light energy of the optical cosmetic device reaches the subcutaneous tissue around the nasolabial folds of the user, promoting cell repair and regeneration and increasing fibroblast activity, thereby activating collagen regeneration and providing three-dimensional support for elastic collagen, thereby achieving cosmetic effects.

[0015] The mask of the optical cosmetic device of the present invention may have a light source disposed opposite the cheek of the user wearing the mask, the light source having a light-emitting element that emits invisible light of a wavelength whose energy reaches deep into the dermis. In this case, the optical cosmetic device delivers invisible light energy to the skin of the user's cheek, increasing the number of fibroblasts and thereby repairing damaged skin and reducing edema and redness, thereby achieving cosmetic effects.

[0016] Example 1 Next, Example 1 embodying the optical cosmetic device of the present invention will be described with reference to the drawings. For ease of explanation, the up-down direction of the mask 3 when worn by a user is referred to as the up-down direction, the direction in which the mask 3 is attached to the user's face when worn by a user is referred to as the rearward direction, the opposite direction is referred to as the forward direction, and the left-right direction when viewed from the front is referred to as the left-right direction. In the three-dimensional Cartesian coordinate system shown in Figures 1 to 3, the positive direction of the X-axis is the "forward direction," the negative direction of the X-axis is the "backward direction," the positive direction of the Y-axis is the "leftward direction," the negative direction of the Y-axis is the "rightward direction," the positive direction of the Z-axis is the "upward direction," and the negative direction of the Z-axis is the "downward direction."

[0017] As shown in Figures 1 to 3, the optical cosmetic device 1 of Example 1 includes a mask 3 and a remote controller 5. The mask 3 includes a mask body 10, a plurality of light sources 30, and an eyeglass unit 50. The mask body 10 is formed with a curved surface so as to cover the entire face of a user wearing the mask 3, and has a generally elliptical shape that is elongated in the vertical direction when viewed from the front.

[0018] As shown in FIG. 3, the mask body 10 includes an outer shell 110, a flexible substrate 130, a concealment film 150, and an inner shell 170. The outer shell 110 is made of PET (polyethylene terephthalate) resin. The outer shell 110 forms the front surface of the mask body 10. The outer shell 110 is opaque. A substantially T-shaped pattern P is formed on the front surface of the outer shell 110. The substantially T-shaped pattern P has a mirrored surface when viewed from the front. A horizontal portion (hereinafter referred to as "horizontal portion P1") extending in the left-right direction of the substantially T-shaped pattern P extends to the eye height of a user wearing the mask 3. This horizontal portion P1 is located in front of the eyeglasses body 510 of the eyeglasses 50, which will be described later. The upper edge of this horizontal portion P1 protrudes slightly forward relative to a surface above the horizontal portion P1. The horizontal portion P1 is a half mirror that transmits light traveling from the rear to the front and reflects light traveling from the front to the rear. In other words, a user wearing the mask 3 can see ahead of the mask 3 through the outer shell 110 of the mask body 10. On the other hand, the face of the user wearing the mask 3 cannot be seen from in front of the mask 3. The portion extending in the vertical direction of the approximately T-shaped pattern P (hereinafter referred to as the "vertical portion P2") gradually narrows in width downward. The lower end of the vertical portion P2 extends to the bottom of the outer shell 110.

[0019] As shown in FIGS. 3 and 4, the flexible substrate 130 is made of a thin insulating material in a substantially circular shape and is bendable. A plurality of notches 131 are formed in the flexible substrate 130. Each notch 131 is substantially slit-shaped. The flexible substrate 130 is bent into a curved shape while overlapping the portions where the notches 131 are formed. The flexible substrate 130 is deformed into a shape that conforms to the rear surface of the outer shell 110 and is placed in contact with the rear surface of the outer shell 110. When placed on the rear surface of the outer shell 110, the flexible substrate 130 has an opening 133 formed in it that corresponds to a horizontal portion P1 of the substantially T-shaped pattern P of the outer shell 110 and that conforms to the outer edge of the front end of the eyeglasses main body 510, which will be described later.

[0020] As shown in FIG. 4, the flexible substrate 130 has 126 light sources 30 arranged on the rear side. As shown in FIG. 5, each light source 30 has a first LED element 31 and a second LED element 32 that emit visible light of different wavelengths, and a third LED element 33 that emits invisible light. Each light source 30 is arranged in the order of the first LED element 31, the second LED element 32, and the third LED element 33. The first to third LED elements 31, 32, and 33 correspond to light-emitting elements. The first to third LED elements 31, 32, and 33 emit light when power is supplied from the remote controller 5 via a connector 175 provided in an inner shell portion 170, which will be described later.

[0021] The first LED element 31 emits yellow light with a wavelength of 590 nm. The second LED element 32 emits red light with a wavelength of 660 nm. The third LED element 33 is selected from four types of LED elements that emit near-infrared light with a wavelength of 850 nm, near-infrared light with a wavelength of 940 nm, short-wave infrared light with a wavelength of 1064 nm, and short-wave infrared light with a wavelength of 1320 nm, depending on the position on the mask 3. That is, the third LED element 33 is selected from four types of LED elements and arranged. More specifically, as shown in FIG. 4 , the third LED element 33 of the light source 30A arranged in area A is an LED element that emits short-wave infrared light with a wavelength of 1064 nm. Area A is located opposite the forehead of a user wearing the mask 3. The third LED elements 33 of the light source 30B arranged in areas B1 and B2 are LED elements that emit near-infrared light with a wavelength of 940 nm. Area B2 is located opposite the cheeks of a user wearing the mask 3. The third LED element 33 of the light source 30C placed in area C is an LED element that emits short-wave infrared light with a wavelength of 1320 nm. Area C is a position facing the nasolabial folds of a user wearing the mask 3. The third LED element 33 of the light source 30 placed in areas other than areas A, B1, B2, and C is an LED element that emits near-infrared light with a wavelength of 850 nm.

[0022] The energy of the light emitted from the first to third LED elements 31, 32, and 33 acts on different layers of the skin, as shown in Figure 6. Specifically, the energy of the yellow light with a wavelength of 590 nm emitted from the first LED element 31 reaches the epidermis and acts directly on the basal layer, the lowest layer of the epidermis, suppressing melanin production, which is the cause of the first step of darkening. In this way, yellow light with a wavelength of 590 nm has cosmetic effects such as improving pigmentation, lightening blemishes, reducing darkness, and improving skin luster.

[0023] The red light with a wavelength of 660 nm emitted from the second LED element 32 reaches the epidermis, increasing cell activity and promoting collagen production. In this way, red light with a wavelength of 660 nm has the cosmetic effect of improving and repairing wrinkles by providing firmness and making wrinkles less noticeable.

[0024] The near-infrared light with a wavelength of 850 nm emitted from the third LED element 33 of the light source 30, which is located in areas other than areas A, B1, B2, and C, has energy that reaches the surface of the dermis, improving the appearance of skin damaged by light and promoting collagen production. Thus, the near-infrared light with a wavelength of 850 nm has the cosmetic effect of improving and repairing wrinkles by providing firmness and making wrinkles less noticeable.

[0025] The near-infrared light with a wavelength of 940 nm emitted from the third LED element 33 of the light source 30B placed in the B1 and B2 areas has energy that reaches the dermis and increases the number of fibroblasts. Thus, the near-infrared light with a wavelength of 940 nm has the cosmetic effect of repairing damaged skin and reducing edema and redness.

[0026] The short-wave infrared light with a wavelength of 1064 nm emitted from the third LED element 33 of the light source 30A located in Area A penetrates deep into the dermis, increasing the thickness of the dermis, collagen fiber density, and fibroblast count. Thus, the short-wave infrared light with a wavelength of 1064 nm has the cosmetic effects of repairing aging dermis, plumping the lower layers of skin, and reducing facial wrinkles.

[0027] The short-wave infrared light with a wavelength of 1320 nm emitted from the third LED element 33 of the light source 30C located in area C has energy that reaches the subcutaneous tissue, promoting cell repair and regeneration and increasing fibroblast activity. In this way, the short-wave infrared light with a wavelength of 1320 nm has the cosmetic effect of activating collagen regeneration and providing three-dimensional support for elastic collagen.

[0028] As shown in FIG. 3, the concealing film 150 is made of PS (polystyrene) resin. The concealing film 150 has a curved shape that conforms to the rear surface of the outer shell 110. The concealing film 150 has circular holes 151 formed in positions corresponding to the 126 light sources 30 arranged on the flexible substrate 130. The concealing film 150 is arranged behind the flexible substrate 130, with the light sources 30, 30A, 30B, and 30C arranged in each hole 151. The concealing film 150 conceals all but the light sources 30, 30A, 30B, and 30C on the flexible substrate 130, making them invisible from behind. The concealing film 150 has an opening 153 formed in a position corresponding to a horizontal portion P1 of the substantially T-shaped pattern P on the outer shell 110, along the outer edge of the front end of the eyeglasses main body 510 (described later).

[0029] The inner shell portion 170 is made of PC (polycarbonate) resin. The inner shell portion 170 has an outer shape that is slightly larger than the outer shape of the outer shell portion 110. The inner shell portion 170 is integrated with the outer shell portion 110 by fitting the outer peripheral edge of the outer shell portion 110 inside the outer peripheral frame portion 171. The inner shell portion 170 forms the rear surface of the mask body 10. The flexible substrate 130 and the concealment film 150 are sandwiched between the inner shell portion 170 and the outer shell portion 110, in this order from the outer shell portion 110 side. The inner shell portion 170 has an opening 173 formed along the outer edge of the front end of the eyeglasses main body 510, which will be described later, at a position corresponding to the horizontal portion P1 of the approximately T-shaped pattern P of the outer shell portion 110. The inner shell portion 170 has a front end 511 of the eyeglasses main body 510, which will be described later, attached and fixed to the opening 173. The inner shell portion 170 has a connector portion 175 at its lower end to which one end of a cable 5C extending from the remote controller 5 is detachably attached.

[0030] As shown in FIGS. 2 and 3, the eyeglasses 50 comprises an eyeglasses body 510 and a pair of temples 530. The eyeglasses body 510 is made of silicone rubber. The eyeglasses body 510 comprises a front end 511, a tube portion 513, and a contact portion 515. The front end 511 of the eyeglasses body 510 has a pair of openings 511A that are long in the left-right direction, formed side by side. A user wearing the mask 3 can see their surroundings through the openings 511A formed in the front end 511 of the eyeglasses body 510 and the half mirror of the outer shell 110 of the mask 3. The front end 511 of the eyeglasses body 510 has a recessed upper portion at the center of the left-right portion.

[0031] The tubular portion 513 of the eyeglasses main body 510 extends rearward from the outer periphery of the front end 511 of the eyeglasses main body 510. The left-right central portion of the lower side of the tubular portion 513 of the eyeglasses main body 510 is recessed upward and extends in the front-to-rear direction. The contact portion 515 of the eyeglasses main body 510 spreads outward from the rear end peripheral edge of the tubular portion 513 of the eyeglasses main body 510. The rear surface of the contact portion 515 of the eyeglasses main body 510 comes into contact with the face around the eyes of the user when the mask 3 is worn by the user. The left-right central portion of the lower side of the contact portion 515 of the eyeglasses main body 510 is recessed upward, and supports the mask 3 by pinching the user's nose from both the left and right sides when the mask 3 is worn by the user.

[0032] Each temple 530 is connected to both ends of the eyeglass body 510 via a hinge. The left and right inner sides of each temple 530 are made of silicone rubber, and the left and right outer sides are made of ABS resin. When the user wears the mask 3, each temple 530 is placed over the user's ears to support the mask 3. Each temple 530 can be folded at the hinge. By making the edges of each temple 530 curved, it is possible to increase the strength against breakage due to dropping, etc.

[0033] As shown in FIG. 1, the remote controller 5 has a main body 5A and an operation button 5B. The other end of a cable 5C, which is connected to the mask body 10, is detachably attached to the main body 5A. The main body 5A contains a storage battery (not shown). The storage battery can be charged via the cable 5C. The operation button 5B is a push button that can be pressed and held down for a certain period of time to turn the power of the light cosmetic device 1 on and off. Each short press of the operation button 5B repeatedly switches between three light emission modes, which will be described later.

[0034] This light-emitting cosmetic device 1 has three light-emitting modes: tightening mode, repair mode, and radiance mode. In the tightening mode, the second LED element 32 and the third LED element 33 of each light source 30, 30A, 30B, and 30C are activated. That is, in the tightening mode, this light-emitting cosmetic device 1 emits red light with a wavelength of 660 nm, near-infrared light with a wavelength of 850 nm, near-infrared light with a wavelength of 940 nm, short-wave infrared light with a wavelength of 1064 nm, and short-wave infrared light with a wavelength of 1320 nm. This tightening mode has the cosmetic effect of regenerating collagen for anti-aging, eliminating excess fat and sagging skin, and reducing the appearance of fine wrinkles to prevent future wrinkles.

[0035] In the repair mode, the first to third LED elements 31, 32, and 33 of the light sources 30, 30A, 30B, and 30C emit light. In other words, in the repair mode, the light-based cosmetic device 1 emits yellow light with a wavelength of 590 nm, red light with a wavelength of 660 nm, near-infrared light with a wavelength of 850 nm, near-infrared light with a wavelength of 940 nm, short-wave infrared light with a wavelength of 1064 nm, and short-wave infrared light with a wavelength of 1320 nm. This repair mode has the cosmetic effect of relieving discomfort during seasonal changes, repairing sensitive redness, and soothing and stabilizing skin after cosmetic surgery.

[0036] In the gloss mode, the first LED element 31 and the third LED element 33 of each light source 30, 30A, 30B, and 30C emit light. In other words, in the gloss mode, the light beauty device 1 emits yellow light with a wavelength of 590 nm, near-infrared light with a wavelength of 850 nm, near-infrared light with a wavelength of 940 nm, short-wave infrared light with a wavelength of 1064 nm, and short-wave infrared light with a wavelength of 1320 nm. This gloss mode eliminates dark yellowing caused by staying up all night, reduces acne scars and sun spots, improves skin discoloration, and provides the beauty benefits of daily whitening care.

[0037] As described above, the optical beauty device 1 of Example 1 is equipped with a mask 3 that covers the user's face. The mask 3 has 126 light sources 30, 30A, 30B, 30C that emit light toward the face of the user wearing it. Each light source 30, 30A, 30B, 30C has a first and second LED element 31, 32 that emits visible light, and a third LED element 33 that emits invisible light.

[0038] This optical beauty device 1 includes light sources 30, 30A, 30B, and 30C each equipped with first and second LED elements 31 and 32 that emit visible light and a third LED element 33 that emits invisible light. Visible light and invisible light have different wavelengths and act on different skin layers, resulting in different effects. Therefore, by emitting visible light and invisible light from each light source 30, 30A, 30B, and 30C, this optical beauty device 1 allows the energy of each light to act on different skin layers, and the synergistic effect of these light sources enhances the beauty effect.

[0039] Therefore, the optical cosmetic device 1 of Example 1 has a high cosmetic effect.

[0040] Each light source 30, 30A, 30B, and 30C of the optical cosmetic device 1 in Example 1 includes a first LED element 31 that emits visible light with a wavelength of 590 nm and a second LED element 32 that emits visible light with a wavelength of 660 nm. Visible light of different wavelengths has different effects on the irradiated skin. Therefore, by emitting visible light of different wavelengths toward the user's face, the optical cosmetic device 1 can achieve different cosmetic effects depending on the wavelength.

[0041] The light sources 30, 30A, 30B, and 30C of the optical cosmetic device 1 of Example 1 each have a third LED element 33 that emits invisible light of different wavelengths (850 nm, 940 nm, 1064 nm, and 1320 nm) depending on their positions on the mask 3. Therefore, by arranging the light sources 30 that emit invisible light of wavelengths appropriate for each part of the user's face at positions corresponding to each part of the face, the optical cosmetic device 1 can achieve a cosmetic effect appropriate for each part of the face.

[0042] The mask 3 of the optical cosmetic device 1 in Example 1 is provided with a light source 30 having a third LED element 33 that emits invisible light with a wavelength of 1064 nm, the energy of which reaches the deep dermis, in area A, which faces the forehead of the wearer. As a result, this optical cosmetic device 1 delivers invisible light energy to the deep dermis of the user's forehead, increasing the thickness of the dermis, collagen fiber density, and the number of fibroblasts, thereby achieving the cosmetic effects of repairing aged dermis, plumping the lower layers of skin, and reducing wrinkles.

[0043] The mask 3 of the optical cosmetic device 1 in Example 1 is provided with a light source 30 having a third LED element 33 that emits invisible light with a wavelength of 1320 nm, the energy of which reaches the subcutaneous tissue, in area C, which faces the nasolabial folds of the user. As a result, this optical cosmetic device 1 allows the invisible light energy to reach the subcutaneous tissue around the user's nasolabial folds, promoting cell repair and regeneration and increasing fibroblast activity, thereby activating collagen regeneration and providing three-dimensional support for elastic collagen, achieving a cosmetic effect.

[0044] The mask 3 of the optical cosmetic device 1 in Example 1 is provided with a light source 30 having a third LED element 33 that emits invisible light with a wavelength of 940 nm, the energy of which reaches deep into the dermis, in area B2, which faces the cheek of the user wearing it. As a result, this optical cosmetic device 1 allows the invisible light energy to reach deep into the dermis of the skin on the user's cheek, increasing the number of fibroblasts and achieving the cosmetic effect of repairing damaged skin and reducing edema and redness.

[0045] The present invention is not limited to the first embodiment described above with reference to the drawings, and the following embodiments are also included within the technical scope of the present invention. (1) The mask does not have to cover the entire face of the user. For example, it may cover only the area above the eyes or only the area below the eyes. (2) Each light source may have one light-emitting element that emits visible light, or three or more light-emitting elements. Each light source may have two or more elements that emit invisible light. The number of light-emitting elements in each light source is not important. (3) The light-emitting element that emits visible light may be of another color. For example, it may be a light-emitting element that emits blue light with a wavelength of 420 nm. A light-emitting cosmetic device using this light-emitting element has the cosmetic effect of killing acne bacteria, tightening pores, and leading to firmer, smoother skin. (4) The wavelength of light emitted by the first LED element may be approximately 590 nm. The wavelength of light emitted by the second LED element may be approximately 660 nm. The wavelength of light emitted by the third LED element may be approximately 850 nm, 940 nm, 1064 nm, or 1320 nm. (5) The number of light sources is not limited to 126. (6) The third LED element does not need to emit light of different wavelengths depending on its position on the mask.
