This invention pertains to a spontaneous emission type photo conversion substance for light therapy which outputs a specific wavelength, and a functional patch and functional mask pack comprising the same, which more specifically, absorbs sunlight and ambient light to perform a light therapy function, and is also an eco-friendly source of energy of a type close to spontaneous emission under the principle of the form of light emission. Furthermore, it is a substance which has been designed in a complex structure that uses a sapphire-based blue axial light fluorescent substance as exciting light in the core having a relatively long light emission time, and also absorbs exciting light by choosing a wavelength at the shell portion for light emission. It pertains to a photo conversion substance having a structure capable of selecting a wavelength in order to efficiently express the light therapy function, and the functional patch and functional mask pack having the light therapy function comprising the same.
Light therapy uses various artificial light sources which output the wavelength of the visible light area or the near infrared ray area (laser, fluorescent lamp, UV Lamp, etc.), and irradiates the human body with the light of a specific wavelength range, thereby penetrating light energy into the subcutaneous layer of the skin and using the principle of promoting biochemical reactions within cells. It facilitates blood circulation, increases the temperature of the skin, expands blood vessels, facilitates metabolism, helps to regenerate skin cells, and strengthens immunity to relieve pain and inflammation. Hence, it is preferred as a method for treating skin diseases or improving skin conditions, while serving the role of relieving muscle fatigue.
Light therapy is a method of improving or treating skin diseases by selectively using a wavelength of 400 nm to 1,300 nm which exerts a positive effect on the skin among the prescribed wavelengths which are output from the light source, and its scope of use is increasingly expanding.
Examining the verified skin improvement effect by each color wavelength according to the light therapy, a wavelength of 400 nm to 420 nm is effective for the cell growth and regeneration cell regeneration, whereas a wavelength of 440 nm to 500 nm is effective for removing acne bacteria, reducing acne inflammation and controlling sebaceous glands. In addition, a wavelength of 500 nm to 520 nm is effective for soothing irritated skin and reducing capillary dilatation, while a wavelength of 520 nm to 562 nm helps to manage complex skin problems and dark spots, and a wavelength of 565 nm to 590 nm is effective for redness and sunburn caused by inflammation. Furthermore, a wavelength of 590 nm to 620 nm is effective for skin vitality, skin improvement and radiance, and a wavelength of 620 nm to 700 nm is effective for improving wrinkles and skin regeneration via promoting collagen production. In addition, a wavelength of 750 nm to 1000 nm exerts the effect of amplifying the therapeutic effect by immersing into the deep layers of the skin.
As such, light therapy is based on the principle where light energy is changed into chemical, kinetic, or thermal energy for physiochemical treatment purposes within the cells, and hence, it is crucial that light is absorbed by elements or molecules within the cells. Furthermore, it is important that the light of a specific wavelength is efficiently absorbed by a specific chromophore in the cells.
For example, the red-based wavelength is used to activate the sebaceous glands in the deep layers of the skin. Furthermore, the blue-based wavelength may be used to regulate the surface conditions of the skin by activating the keratin in the epidermis by using the photodynamic therapy (PTD).
Meanwhile, most of the LED light emitting elements are used as the light source which outputs a prescribed light for the light therapy.
As an example of a previous technology which uses an LED light emitting element as a light source, a patch-type light therapy product of “patch-type skin treatment device (Registered Korean Patent No. 10-1829984)” has been commenced. Furthermore, the previous technology above requires multiple LED chips that irradiate light of a certain wavelength range on the skin when power is supplied. In addition, it comprises an LED patch unit having a zigzag pattern in order that the circuit pattern connecting the LED chip above is flexibly changed according to the changes of the form above.
Also, as another previous technology, a “photo mask device for skin beauty (Registered Korean Patent No. 10-1074882)” has been commenced. Furthermore, this requires a light emission unit which is mounted in the face mask to emit light onto the face of a user wearing the face mask, a light emission driver unit which drives the light emission unit on/off, and an operation unit which selects the driving of the light emission unit, and a control unit which controls the light emission driving unit according to the operation signals of the operation unit.
As in the above, the devices which exert light therapy effects by using the LED light emitting elements have limitations in applicable products and production costs are quite high due to the indispensable requirement of the electric circuits for driving the LED light emitting elements and the means of power supply.
Furthermore, there is an issue in the fact that it is inconvenient to use, ineffective in terms of portability, inconvenient due to standby for charging, and the risk of exposure to electromagnetic waves as devices used for the human body.
Meanwhile, in the case of a conventional spontaneous emission axial light fluorescent substance which absorbs ambient light and which is used as the principle of axial light, the light emission time is short and hence unsatisfactory since the blue light emission region is a high energy band, and the durability is weak.

This will describe in detail the spontaneous emission type photo conversion substance for light therapy and the preparing method according to this invention by making reference to the attached
As illustrated in
At which time, the blue light exciting core (12) is made of a sapphire-based blue axial light fluorescent substance, and the photo conversion shell above (14) is made of a photo conversion substance. Thus, in the case of the spontaneous emission type photo conversion substance for light therapy (10), it has a relatively long light emission time and absorbs sunlight and ambient light, absorbs the exciting light above in the photo conversion shell above (14) enveloping the blue light exciting core above (12) which outputs the exciting light, thereby executing the photo conversion with the wavelength selected for light emission as a matter of technical characteristic.
That is, in the case of the spontaneous emission type photo conversion substance for light therapy (10), the exciting light output from the blue light exciting core above (12) is absorbed by the photo conversion shell (14) and converted into a prescribed wavelength for light therapy, after which it outputs as the light of the wavelength having the light therapy effect, and hence, is a fluorescent substance which executes spontaneous emission.
As illustrated in
Specifically, in order to prepare the sapphire-based blue axial light fluorescent substance forming the blue light exciting core above (12) of the spontaneous emission type photo conversion substance for light therapy (10), the mixture generation step above (S10) produces the mixture by mixing raw materials made of inorganic oxides in line with the above chemical equivalence ratio with metals of 1 type or more of Ba, Sr, Ca, Mg, Eu, or Dy for M above of the chemical formula of Ma Al2O3.
At which time, the range according to the formula of the mixture generation step above (S10) is desirable to be 0≤a<1. Furthermore, the inorganic oxide raw materials may add Europium or Dysprosium for matrix as for Al2O3 which corresponds to aluminate, which is sapphire, or add Calcium or Strontium or Barium or Magnesium for formation.
In the heat treatment of the mixture above (S11), the mixture generated in the heat treatment of the mixture above (S10) is heated to perform the heat treatment.
In which event, the heat treatment of the mixture step above (S11) may be performed by heating at 1,000° C. to 1,500° C. for 2 to 12 hours, and the heat treatment of the mixture as such may be performed in a reducing atmosphere.
In the natural cooling of the mixture above (S12), the mixture which is heat treated through the heat treatment of the mixture above (S11) is gradually and naturally cooled at the room temperature.
In the mixture surface treatment step above (S13), the mixture naturally cooled through the mixture natural cooling step above (S12), and the alcohol and silicon nitride balls are mixed at the ratio of 2:1:2. Following which, the mixture is stirred at 1,000 rpm to 5,000 rpm for 1 hour to 5 hours, and the mixture above is crushed with physical force to treat the surface defects.
In the case of the mixture surface treatment step above (S13), the spontaneous emission type photo conversion substance for light therapy above (10) is performed in order to have a relatively longer afterglow characteristic. At which time, it is desirable to control the particle size of the crushed mixture to be formed in the range of 15 μm to 20 μm.
Meanwhile, in order to prepare the photo conversion substance forming the photo conversion shell (14), first, the photo conversion raw material mixture generation step above (S20) produces the photo conversion raw material mixture by mixing the photo conversion raw material and alcohol and silicon nitride ball which mix any one of or more than one of the substances belonging to the green conversion substance, which is identical to the photo conversion raw material listed in Table 1, yellow conversion substance, red conversion substance, and the near infrared ray conversion substance at the ratio of 1:3:2.
That is, in the case of the photo conversion raw material forming the photo conversion shell above (14), as provided in Table 1, any one of or more than one of the green conversion substance, yellow conversion substance, red conversion substance, and the near infrared ray conversion substance can be formed in combination. Furthermore, the green conversion substance and the yellow conversion substance may be YAG (Y3Al5012:Ce), LuAG (Lu3Al5O12:Ce), M=(Ca,Sr,Ba), M2SiO4:Eu, M3SiO5:Eu, MSi2O2N2:Eu, α-SiAlON, β-SiAlON, etc. In addition, the red conversion substance above may be, as an example of the red conversion substance as such, M=(Ca,Sr,Ba), MAlSiN3:Eu, M2Si5N8, K2SiF6:Mn, etc.
*94 Furthermore, the near infrared ray conversion substance above comprises zinc, gallium, and scandium oxides and manganese or chromium or neodymium as transition elements.
The crushing and surface treatment step above (S21) is a process intended for producing a slurry form by crushing and surface treating the photo conversion raw material mixture which is generated in the photo conversion raw material mixture generating step above (S20) by using a planetary ball mill method. At which time, it is desirable that the planetary ball mill be 5,000 rpm or more.
The photo conversion substance prepared as such forms the photo conversion shell above (14) outputs the proven wavelength for pain relief, sterilization, prevention of wound infection, and the vitamin D formation by taking the input of the wavelength of the ultraviolet to blue area output from the sapphire-based blue axial light fluorescent substance forming the blue light exciting core above (12).
For example, the red conversion substance above or the near infrared ray conversion substance outputs light of the wavelength which aids skin regeneration.
That is, the spontaneous emission type photo conversion substance for light therapy above (10) is formed from the sapphire-based blue axial light fluorescent substance and the photo conversion substance. Hence, while outputting the wavelength of the blue area of 400 nm to 500 nm, which exerts effects such as pain relief, sterilization, wound infection prevention, and vitamin D generation, it also outputs the near ultraviolet rays effective for atopy, or 780 nm, which are effective for skin regeneration, or can output the near infrared ray of 2.5 μm wavelength.
Meanwhile, in the case of the mixture solution generation step above (S30) to form the complex structure of the spontaneous emission type photo conversion substance for light therapy (10), a mixed solution is produced by mixing the sapphire-based blue axial light fluorescent substance prepared through the mixture generation step above (S10) or the photo conversion raw material mixture generation step (S20) and the photo conversion substance above in the form of a slurry prepared through the photo conversion raw material mixture generation step above (S20) or the crushing and surface treatment step above (S21).
Thereafter, through the photo conversion shell formation step above (S40), the mixed solution above generated in the mixed solution generation step (S30) is heat treated whereby the photo conversion shell above (14) made of the photo conversion substance above will be formed at the blue light exciting core above (12) made of the sapphire blue axial light fluorescent substance.
Specifically, in the case of the photo conversion shell formation step above (40), sodium oleate and dispersant for attaching the sapphire-based blue axial light fluorescent substance above and the photo conversion substance above to the mixed solution generated in the mixed solution generation step above (S30) will be added. After which, alcohol is removed by heating the mixed solution above stabilized through the stabilization step (S42) and the stabilization step above (S42) of letting the stirred mixed solution to be left at the room temperature for 1 to 3 hours after undergoing the mixed solution stirring step (S41) and the mixed solution stirring step (S41) for 30 to 120 minutes. In addition, this comprises a photo conversion shell formation step (S43) of forming a photo conversion shell made of a photo conversion substance on the blue light exciting core.
At which time, it is desirable that the stabilization step above (S42) further comprises the washing step of washing by using ethanol or ultrapure water.
In addition,
As compared through
This is intended to ensure that the spontaneous emission type photo conversion substance for light therapy above (10) has a relatively longer long afterglow characteristic, and it can be known that as for such characteristic, the light emission time is longer than before, as illustrated
In particular, the sapphire-based blue axial light fluorescent substance above absorbs ambient light by controlling the particle size of 15 to 20 μm by physical force and performing surface defect treatment through the mixture surface treatment step above (S13). Hence, as illustrated
As examined earlier, through the mixed solution generating step above (S30), the sapphire-based blue axial light fluorescent substance illustrated in
At which time, the photo conversion shell above (14) formed outside of the blue light exciting core above (12) in the photo conversion shell formation step (S40) is formed differently depending on the temperature and time. Furthermore, the higher the temperature and the longer it is heated, the photo conversion shell is formed while completely enveloping the blue light exciting core, as illustrated in
Furthermore, as verified through
Hence, since the photo conversion shell above (14) is completely or incompletely formed on the blue light exciting core above (12), the spontaneous emission wavelengths is generated differently from each other. In addition, when the spontaneous emission type photo conversion substance for light therapy above (10) is completely formed by being enveloped entirely by the photo conversion shell above (14) on the blue light exciting core above (12), the efficiency is high. Whereas, when the photo conversion shell above (14) is incompletely formed, the photo conversion substance is sparsely attached to the blue light exciting core, and hence, the conversion efficiency will decline.
However, when selecting the wavelength of light therapy, if it is necessary to select functions such as sterilization and disinfection, which are blue functions, with priority, it is desirable that the photo conversion shell above (14) use the spontaneous emission type photo conversion substance for light therapy above (10) which is incompletely formed as in
As illustrated in
Hence, the light emission color can be adjusted by regulating the content ratio of the photo conversion substance above to the sapphire-based blue axial light fluorescent substance above.
Meanwhile, the spontaneous emission type photo conversion substance for light therapy according to this invention can be applied as a means of light emission for various products to add light therapy effect without electrical energy. In particular, it can be applied as a means of light emission such as a skin cosmetic or medical patch or a skin cosmetic mask pack.
Hereinbelow, by making reference to the attached Drawings 10 through 12, as for the form of implementation of this invention, a functional patch comprising a spontaneous emission type photo conversion substance for light therapy will be described.
As illustrated in
At which time, the patch main unit above (101) can be formed in various shapes and sizes such as a square, a rectangle, a circle, and an oval so that it can be attached to and used on various parts of the body. In addition, it is made of a fibrous material, yet has a thickness of several mm and has an overall elasticity so that it can be easily adhered to a curved part of the skin.
Desirably, as an implementation example of the patch main unit above (101), it can be made of a fibrous material, and in particular, it is desirable that it be formed of a printable sheet of fibrous material such as a printable cotton sheet, non-woven sheet, and cellulose sheet, etc. Furthermore, more desirably, it can be made of TENCEL fabric.
As it is known, TENCEL fabric is a functional natural material developed by Lenzing, an Austrian textile company, and is also an eco-friendly material made of eucalyptus tree extracts, and hence, has excellent moisture contents and water absorption. Furthermore, it is effective for sensitive skin as the fiber structure is smooth and it does not irritate the skin.
Furthermore, as another implementation example of the patch main unit above (101), it can be made of a hydrogel, a material having a three-dimensional hydrophilic polymer network structure using purified water as a dispersion medium in order to improve adhesion to the skin and moisturizing ability. At which time, the hydrogel forming the patch main unit above (101) can be formed of various viscoelastic polymers known in the industry such as hyaluronic acid, agarose, alginate, chitosan, gelatin or collagen.
Furthermore, it is apparent that the patch main unit above (101) is not limited to the aforesaid implementation examples and can also be implemented in other forms.
In addition, an adhesive material is applied in the rear of the patch main unit above (101), that is, the inner surface of the patch main unit above (10) which directly contacts the skin, which makes attachment to the body easy.
Moreover, it is formed relatively wider than the patch main unit above (101) and an adhesive material is applied on one side. Hence, it may further include an adhesive fabric (102) attached to the body while covering the patch main unit (101) attached to the user's body to maintain the attachment state of the patch main unit (101). The adhesive fabric above (102) may generally be a conventional adhesive fabric used to maintain the attachment state of the patch and prevent contamination from against the outside, and may also be formed of the same material as the patch main unit above (101).
Meanwhile, when the functional patch (100) comprising the spontaneous emission type photo conversion substance for light therapy of this invention is used for the prescribed therapeutic purpose, it can comprise various pharmaceutical ingredients according to the therapeutic purpose.
As illustrated in
Specifically, the patch main unit above (101) can be printed in the entire rear surface of the patch main unit above (101), and can be printed in the entire rear surface of the patch main unit above (101) in a striped pattern, or can be printed in a grid pattern.
When the means of light emission above (110) is formed by printing in a stripe pattern or a grid pattern, the entire face may sufficiently be provided with the light therapy effect while reducing the raw materials required to form the means of light emission above (110) relative to the case where the means of light emission above (110) is printed across the entire rear surface.
Here, when the means of light emission above (110) is printed in the form of a stripe pattern or a grid pattern in the rear surface of the patch main unit above (101), it is desirable that the spacing between the lines and the lines or between the grids be made of a distance between 2 mm and 5 mm.
Furthermore, the means of light emission above (110) is not limited to the form illustrated in
Hereinbelow, by making reference to the attached

First, the mask sheet above (201) is formed in a shape corresponding to it, so as to be in close contact with the user's face to cover all or some part of the user's face.
Furthermore, the mask sheet above (201), as an implementation example, may be made of a fibrous material, and in particular, it is desirable that it be formed of a printable fibrous material sheet such as a printable cotton sheet, a non-woven sheet, a cellulose sheet, and more desirably, it can be made of TENCEL fabric.
As it is known, TENCEL fabric is a functional natural material developed by Lenzing, an Austrian textile company and is also an eco-friendly material made of eucalyptus tree extract. It has excellent moisture content and absorption, and its smooth fiber structure does not irritate the skin. Hence, it is effective for sensitive skin.
Furthermore, as another implementation example, the mask sheet above (201) may be made of a hydrogel, a material having a three-dimensional hydrophilic polymer network structure using purified water as a dispersion medium in order to improve adhesion and moisturizing ability with the skin. At which time, the hydrogel forming the mask sheet above (201) can be formed by comprising various viscoelastic polymers publicly known in the industry such as hyaluronic acid, agarose, alginate, chitosan, gelatin or collagen.
In addition, it is apparent that the mask sheet above (201) is not limited to the above-mentioned implementation examples and may be implemented in other forms.
Furthermore, the lotion immersed in the mask sheet above (201) can be a material of various natural or chemical components which are helpful for the skin, such as whitening, whitening, nutrition, and wrinkle improvement, depending on the component, and is not limited to a specific material.
In addition, the mask sheet above (201) may further comprise an extension unit (202) having a length and a width connected to a part covering the forehead of the face to cover the head.
The extension unit above (202) has a length and width that can cover the head, so that the functional mask pack (200) comprising the spontaneous emission type photo conversion substance for light therapy of this invention executes light therapy functions on not only the user's face, but also on the scalp of the head.
As illustrated in
Specifically, the mask sheet above (201) may be printed across the entire rear surface of the mask sheet above (201), and may also be printed on the entire rear surface of the mask sheet above (201) in a striped pattern or printed in a grid pattern.
When the means of light emission above (210) is formed by printing in a stripe pattern or a grid pattern, the light therapy effect can be provided sufficiently across the entire face while reducing the raw materials required to form the means of light emission above (210) relative to the case where the means of light emission above (210) is printed across the entire rear surface.
Here, when the means of light emission above (210) is printed in the form of a stripe pattern or a grid pattern in the rear of the patch main unit above (201), it is desirable that the spacing between the lines and the lines or between the grids be made in 5 mm to 10 mm.
Moreover, when intensive care is required on a specific area of the face such as around the eyes, around the lips, and the forehead, the means of light emission above (210) should ensure that rear area of the mask sheet above (201) corresponding to a specific area such as around the eyes, around the lips, and forehead is printed in a relatively large area relative to other areas such as cheeks and chin, so that a relatively large amount of light is supplied to the skin.
Various forms in which the means of light emission above (210) are printed in the rear surface of the mask sheet above (10) have been described through
