Description

SKIN CARE DEVICE}

The present invention relates to an apparatus for improving skin using light.

Light that is injected into the skin can damage the skin, but it can also improve the skin by promoting the metabolism of the skin.

A typical example of light that damages the skin is ultraviolet rays. When photographing the spectrum of sunlight, light that is not visible to the naked eye at shorter wavelengths than visible light is called ultraviolet light, which can burn and damage the skin. Excessive exposure of the skin can cause skin cancer due to these ultraviolet rays.

Unlike these ultraviolet rays, light of a certain wavelength is known to improve the skin by promoting metabolism of the skin. These light of some wavelengths can be used for low level laser treatment (LLLT). This LLLT changes the light reaching the living body into heat and the temperature of the living body is raised by this heat, so that the blood circulation in the living body becomes active, Is a technique to treat skin by using the principle that it is better.

Generally, when the light used in the LLLT is injected into the living body, heat is generated in the living body. At this time, the living body temperature is less than 40 degrees. These body temperatures not only activate cells and tissues, but also stimulate blood circulation and metabolism in the body.

Conventionally, LLLT has been implemented by a skin treatment device using a semiconductor laser.

Semiconductor lasers are semiconductors of potassium, aluminum, and arsenic, which generate various wavelengths from visible to near infrared. Conventional skin treatment devices use such semiconductor lasers to emit light with a low reaction level ranging from 1 mW to 400 mW, thereby promoting the activation of biomaterials without causing cell destruction.

However, in order to implement such a skin treatment apparatus, it is necessary to have not only the above-mentioned semiconductor laser but also a power supply device for supplying power to the semiconductor laser and a power control device for controlling the output of the power supply device.

Conventional skin treatment apparatuses have a problem that their manufacturing cost is high due to such structures, and they also involve a bulky and heavy structure like a power supply apparatus, which makes it difficult to carry them.

In view of the foregoing, an object of the present invention is, in one aspect, to provide a technique for an apparatus which improves the skin by using light and is low in manufacturing cost.

In another aspect, an object of the present invention is to provide a technique for a portable device as a device for improving skin using light.

In another aspect, an object of the present invention is to provide a technique for an apparatus for improving skin by using ambient light without separately generating light.

In order to achieve the above-mentioned object, in one aspect, the present invention provides a light source device comprising a first surface located in a direction in which natural light or artificial light is incident, a second surface positioned in a skin direction of the human body, And a phosphor material which absorbs light of a first wavelength from the natural light or artificial light and is excited and then relaxed to emit light of a second wavelength to the skin of the human body A phosphor layer; and the light of the second wavelength penetrates into the skin tissue of the human body to cause biological stimulation to the skin tissue.

As described above, according to the present invention, it is possible to manufacture a skin improving device which is cheap and easy to carry.

1 is a configuration diagram of a skin care apparatus 100 according to an embodiment of the present invention.

Hereinafter, an apparatus for improving skin according to an embodiment of the present invention will be described as a skin care device, but the present invention is not limited thereto.

1, the skin care apparatus 100 includes a first surface 110 positioned in a direction in which natural or artificial light is incident, a second surface 130 positioned in the skin direction of the human body, And a phosphor layer 120 positioned between the first surface 130 and the second surface 130.

Natural light or artificial light is incident on the first surface 110. Such natural or artificial light can be referred to as incident light 140. The incident light 140 is not generated by the skin care apparatus 100 as ambient light. For example, solar light or illumination can be such incident light 140.

Therapeutic light 150 is output to the second surface 130. Therapeutic light 150 penetrates into the skin of the human body and enables the cells and tissues in the skin to be activated.

Phosphor layer 120 is a layer containing a phosphor material 122.

The phosphorescent material is a material which emits light of one wavelength as a luminescent material and emits light of a different wavelength after being excited and relaxed. As such phosphor materials, Y ₂ O ₃ : Eu, (Y, Gd) BO ₃ : Eu and Gd ₂ O ₃ : Eu, Li and the like can be used.

The skin care apparatus 100 according to an embodiment of the present invention may convert incident light 140 transmitted through the first surface 110 into a curing light 150 after the phosphor material absorbs the curing light 150, It is a device that improves skin.

2 is a view showing the wavelength of light changed by a phosphor material.

Referring to FIG. 2, the phosphor material absorbs one wavelength of light and then emits light of another wavelength. The phosphorescent material shown in FIG. 2 absorbs light of wavelengths near 260 nm, 410 nm, and 570 nm, and then absorbs light having wavelengths near 700 nm, Of light.

FIG. 2 also shows a spectrum 230 of sunlight. Referring to FIG. 2, the sunlight represents a continuous spectrum including all the light ranging from 240 nm to 840 nm.

When the skin care apparatus 100 uses the solar light as the incident light 140, the phosphor material 122 included in the phosphor layer 120 absorbs the light of wavelengths near 260 nm, 410 nm, and 570 nm. The intensity of light of such a wavelength in the incident light 140 is reduced. In addition, since the phosphor material 122 emits light at a wavelength 220 near 700 nm, the light intensity at this wavelength increases. As a result, the intensity of the wavelength 210 around 260 nm, 410 nm and 570 nm decreases and the intensity of the wavelength 220 around 700 nm increases in the therapeutic light 150 emitted by the skin care apparatus 100. Accordingly, the treatment light 150 becomes a light having an enhanced intensity of light of a specific wavelength. In another aspect, the treatment light 150 is a light whose intensity of light of another specific wavelength is reduced.

In a stepwise manner, the phosphor material is in a low-energy state (first step) and absorbs light of a first wavelength in the light entering the incident light 140, resulting in a high-energy state (second step) . The phosphor material is then relaxed in the high energy state and emits light of the second wavelength (step 3). Then, the phosphor material is again turned into a low energy state and circulated through the first to third steps described above. Here, the first wavelength may be a wavelength 210 near 260 nm, 410 nm, and 570 nm as described above, and the second wavelength may be a wavelength 220 near 700 nm.

Meanwhile, the penetration depth into the skin differs according to the wavelength of light, and the skin care apparatus 100 can create various skin improvement effects according to the penetration depth of light according to such wavelengths.

Fig. 3 is a diagram showing the penetration depth into the skin for each wavelength of light.

Referring to FIG. 3, the skin is composed of an epidermis, a dermis, and a hypodermis, and has different penetration depths depending on wavelengths of light.

Generally, the longer the wavelength, the greater the penetration depth of light. However, this tendency is not consistent as can be seen from the fact that the penetration depth of light at 940-1100 nm wavelength is shorter than the penetration depth of light at 780-940 nm wavelength.

Depending on the penetration depth of the light, the area of the light that is affected by the skin also varies. For example, shorter wavelengths of light (150-380 nm and 390-470 nm in FIG. 3) mainly affect the epidermis , The middle wavelengths of light (475-545 nm and 545-500 nm in FIG. 3) mainly affect the dermis and long wavelengths of light (500-650 nm and 780-940 nm in FIG. 3) It affects Hypodermis. Here, short-wavelength lights (light of 150-380 nm and 390-470 nm in FIG. 3) correspond to ultraviolet light or purple visible light, and intermediate-wavelength lights (light of 475-545 nm and 545-500 nm in FIG. 3) Or yellow visible light, and long wavelengths of light (500-650 nm and 780-940 nm in FIG. 3) correspond to red visible light or near-infrared light.

The skin care apparatus 100 can emit the treatment light 150 having a strong intensity of light of a specific wavelength (a specific color depending on the wavelength) according to the skin improvement effect to be created. For example, the skin care device 100 may emit red light into the curing light 150 for metabolic, moisturizing, wrinkle-improving, elastic strengthening, and the like. In addition, the skin care apparatus 100 can emit blue light into the curing light 150 for bacteria sterilization, skin cleansing, skin activation, stimulation of wound healing, and the like. The skin care apparatus 100 can emit green light to the treatment light 150 for melanin pigment reduction and gland control, and can treat the yellow light for treatment of pigment degradation, lymphotoxin dissolution, skin roughness, (150). ≪ / RTI >

The skin care apparatus 100 may optionally include a phosphor material in the phosphor layer 120 that emits light of a specific color (a specific wavelength) to the treatment light 150 for creating a specific skin effect. For example, the skin care device 100 may include a phosphor material such as Zn ₃ SiO ₄ : Mn, YBO ₃ : Tb, and BaAl ₁₂ O ₁₉ : Mn to release green light into the curing light 150. These phosphor materials emit green light mainly when they are induced and relaxed.

As another example, the skin care device 100 may include a phosphor material such as Y ₂ O ₃ : Eu, (Y, Gd) BO ₃ : Eu, Gd ₂ O ₃ : Eu, ), And blue light can be emitted to the curing light 150 by including phosphor materials such as Sr ₃ Al ₁₆ O ₂₅ : Eu, Dy, Y ₂ O ₂ S: Eu, and ZnGa ₂ O ₄ , Zn ₃ Ga ₂ Ge ₂ O ₁₀ : 0.5% Cr ^{3 +,} and the like, so that the near-infrared light can be emitted as the treatment light 150.

On the other hand, some additional layers may be located above and below the phosphor layer 120. At this time, the first surface 110 becomes the uppermost surface in the direction of the incident light 140, and the second surface 130 becomes the lowest surface in the direction of the treatment light 140.

Figure 4 is a cross-sectional view of a skin care device according to an embodiment in which additional layers are further positioned in the phosphor layer.

Referring to FIG. 4, the skin care apparatus 100 may further include a prism layer 440 positioned between the first surface 110 and the phosphor layer 120.

The prism layer 440 may spectrally separate light (for example, natural light) incident on the first surface 110 in the direction of the first surface 110 and transmit the separated light to the phosphor layer 120. When the prism layer 440 spectrally separates the incident light, the light of a certain wavelength can be transmitted to the phosphors 122a, 122b and 122c of the phosphor layer 120, Lt; RTI ID = 0.0 > 120 < / RTI >

When the skin care device 100 desires to emit red visible light through the skin, the red visible light is directly transmitted through the prism layer 440 below the phosphor layer 120, and the remaining light is transmitted through the phosphor materials 122a, 122b, and 122c, and the phosphors 122a, 122b, and 122c emit red visible light according to the wavelength conversion of the light.

In addition, the skin care device 100 may include different phosphors 122a, 122b, and 122c, and may transmit light of different bands to the respective phosphors 122a, 122b, and 122c. For example, the first phosphor material 122a located in the phosphor layer 120 converts the blue light into red light, the second phosphor material 122b converts the green light to red light, and the third phosphor material The skin care apparatus 100 allows the blue light separated from the prism layer 440 to be transmitted to the first phosphor material 122a and the blue phosphor separated from the prism layer 440 The green light may be transmitted to the second phosphor material 122b and the yellow light separated from the prism layer 440 may be transmitted to the third phosphor material 122c.

On the other hand, the prism layer 440 can totally absorb light incident from the second surface 130. For example, a portion of the incident light 140 transmitted to the phosphor layer 120 may be reflected after it hits the phosphor layer 120 or a layer below it, and may be returned toward the first surface 110, The second light source 440 may totally return the returned light to the second surface 130 side. In addition, light emitted by the phosphors 122a, 122b and 122c in the phosphor layer 120 may be directed toward the first surface 110 without facing the second surface 130, The light directed toward the surface 110 may be totally reflected by the prism layer 440 toward the second surface 130.

On the other hand, the prism layer 440 may be in surface contact with the phosphor layer 120 to form total reflection. If the refractive index of the medium of one layer is smaller than the refractive index of the medium of the other layer, the refractive index of the prism layer 440 medium 454 is lower than the refractive index of the medium of the phosphor layer 120, The light directed from the phosphor layer 120 to the prism layer 440 may be totally reflected by the lower surface 456 of the prism layer 440. [

The prism layer 440 may include a plurality of triangular prisms 450. One side of the triangular prism 450 may be in contact with the phosphor layer 120. If the prism layer 440 is formed of a plurality of triangular prisms 450, the entire prism layer 440 can be flexibly bent even if the triangular prism 450 is made of a hard material.

On the other hand, the phosphor layer 120 may include one type of phosphor material, or may include two or more types of phosphor materials. Referring to FIG. 4, the phosphor layer 120 includes three phosphor materials 122a, 122b, and 122c of different kinds, each of which emits light of different wavelengths, ) Can emit light of three wavelengths as the treatment light 150. The phosphor layer 120 may emit a therapeutic light 150 that includes two or more phosphorescent materials and can simultaneously produce various skin-improving effects.

4, the skin care apparatus 100 may further include an ultraviolet barrier layer 460 positioned between the second surface 130 and the phosphor layer 120. [ When the incident light 140 entering the first surface 110 is sunlight, the incident light 140 may include ultraviolet rays. The ultraviolet ray blocking layer 460 may transmit ultraviolet rays passing through the phosphor layer 120, As shown in FIG.

The skin care apparatus 100 may further include a skin contact layer 470 having a first surface 130 and a bio-compatible material (e.g., collagen). The skin care apparatus 100 may be adhered to the skin according to an embodiment. At this time, the skin care apparatus 100 may further include a skin contact layer 470 made of a biocompatible material so as not to cause trouble to the skin.

The skin care device 100 may be implemented in various forms of embodiments. Shapes in which the one surface is in the ambient light direction and the other surface is in the skin direction may all be embodiments of the skin care device 100. For example, the hat is a form in which the skin care apparatus 100 can be applied because one side can receive sunlight in the sky direction and the other side is in the skin direction. Hereinafter, some forms in which the skin care apparatus 100 can be applied will be described.

Although several embodiments of the skin care device have been described above, the present invention is not limited thereto. As described above, it should be understood that the embodiments that include a phosphor material that emits the light of the first wavelength and emit the light of the second wavelength, and that produce the skin improvement effect, are all examples of the present invention.

The present invention attenuates the intensity of the first wavelength light and increases the intensity of the second wavelength light through the phosphor material. This makes it possible to produce light with enhanced intensity of light of a specific wavelength (second wavelength) in natural light or ambient light of artificial light. Also, on the other side, the intensity of another specific wavelength (first wavelength) can produce attenuated light. The fact that the light intensity of the specific wavelength (second wavelength) from the ambient light can be enhanced can make light of a desired wavelength without implementing a separate light source device. In addition, the ability to produce attenuated light of other specific wavelengths (first wavelength) from ambient light means that it is possible to block undesired wavelengths of light without a separate awning device.

As a result, the embodiments of the present invention can provide a skin improvement device having a low manufacturing cost and being portable.

Recently, the device for improving skin using light has been changed from a device for administering strong light to the skin in a short period of time and a device for administering light of low intensity to the skin for a long time. However, there has been a problem in that a method of administering light with low intensity to the skin for a long time consumes a lot of time by the user.

The skin care device according to the embodiment of the present invention is also an apparatus that can administer light of low intensity to the skin for a long time. However, the skin care device according to the embodiment of the present invention can be implemented in a form frequently used in everyday life, so that the skin improvement effect can be created without consuming the user's time separately. For example, if a user wears a skin care device in the form of a cap 500, light with low intensity can be administered to the skin for a long time. Therefore, the user can make a skin improvement effect without consuming time separately in daily life.
