Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art can easily implement the present invention. The present invention may be implemented in various different forms, and is not limited to the embodiments described herein. In the drawings, parts not related to the description are omitted in order to clearly describe the present invention, and the same reference numerals are added to the same or similar components throughout the specification.

The LED patches 100, 100 ′, 200 for skin care devices according to an embodiment of the present invention may irradiate light of a predetermined wavelength band toward the user's skin through a light source while attached to the user's skin.

Through this, the user can obtain a beneficial effect by using the light irradiated from the skin care device LED patch (100, 100', 200) according to an embodiment of the present invention.

As an example, the LED patch for a skin care device according to an embodiment of the present invention (100, 100', 200) is attached to the user's skin through a liquid or gel material such as ampoules, essences, and cosmetics applied to the user's skin. Can be.

Further, in the LED patch 100, 100', 200 for a skin care device according to an embodiment of the present invention, one surface facing the user's skin may be directly attached to the user's skin even if a separate member or material is not used.

To this end, the LED patches 100, 100', 200 for skin care devices according to an embodiment of the present invention are light source units 110, 110' as shown in Figs. 1, 2, 5, 6, 9, and 10. ) And a cover part 120 may be included.

The light source units 110 and 110 ′ may generate light in a predetermined wavelength band when power is supplied. To this end, the light source units 110 and 110 ′ include a substrate unit 111 and circuit pattern units 113 and 113 ′ formed on the substrate unit 111 and the circuit pattern units as shown in FIGS. 3, 7 and 11. It may include at least one LED 112 mounted on one surface of the substrate 111 through (113, 113').

In this case, the substrate part 111 may be a plate-shaped member having a predetermined area, and a plurality of the LEDs 112 may be provided, and the plurality of LEDs 112 may include the circuit pattern parts 113 and 113 ′. Through this, it may be mounted on one surface of the substrate part 111.

Through this, the plurality of LEDs 112 may be arranged on one surface of the substrate part 111 in a predetermined pattern, and may be electrically connected to each other through the circuit pattern parts 113 and 113 ′.

Accordingly, the light source units 110 and 110 ′ may form a surface light source through a plurality of LEDs 112 arranged on one surface of the substrate unit 111, and the LED for a skin care device according to an embodiment of the present invention The patches 100, 100 ′ and 200 may irradiate light onto the user's skin over a large area by using light generated in the form of a surface light source from the light source units 110 and 110 ′.

In this case, the substrate part 111 may have flexibility and elasticity. Through this, even if the LED patches 100, 100', 200 for skin care devices according to an embodiment of the present invention are attached to a curved body part such as a face, the LED patches 100, 100', 200 for skin care devices are curved. The shape of the surface light source can be maintained by being deformed in response to the body part.

To this end, the substrate part 111 may be formed of a porous substrate having pores.

For example, the porous substrate may be fabric, fabric, nonwoven fabric, porous film, membrane, or the like. However, the porous substrate is not limited to the above-described material, and may be used without limitation as long as it has elasticity and flexibility and pores of a predetermined size are formed.

As a specific example, the substrate part 111 may be a nanofiber web accumulated in a three-dimensional network structure so that the nanofibers 111a including the synthetic polymer have pores 111b as shown in FIG. 14.

In this case, the circuit pattern portions 113 and 113 ′ may be formed on at least one surface of the substrate portion 111. Accordingly, the substrate part 111 may serve as a circuit board capable of mounting electronic components such as the LED 112.

Through this, in the case where the substrate portion 111 is formed of a nanofiber web in the LED patch (100, 100', 200) for a skin care device according to an embodiment of the present invention, the substrate portion 111 is a conventional flexible circuit Compared to the polyimide film used as a substrate, the curvature may be significantly superior, and even if it is folded or wrinkled, it may have excellent restoration properties that can be restored to its original state.

As a non-limiting example, the substrate part 111 may be a single-layer or multi-layer nanofiber web accumulated to have pores 111b by electrospinning a spinning solution in which a synthetic polymer and a solvent are mixed. Here, the solvent may be water or alcohol, and an organic solvent such as dimethylacetamide or acetone may be used alone or in a mixed form in addition to water or alcohol.

In this case, the synthetic polymer may be a fiber-forming polymer capable of implementing a nanofiber web through electrospinning while having elasticity and elasticity. As a specific example, the synthetic polymer may be polyvinylidene fluoride (PVDF) alone, but PVDF and PES (polyethersulfone) are used in a predetermined ratio to ensure heat resistance to high temperatures during soldering of the LED 112. May be mixed.

However, the material of the synthetic polymer is not limited thereto, and any fiber-forming polymer having flexibility and elasticity while implementing a nanofiber web through electrospinning may be used without limitation.

As described above, in the LED patch 100, 100', 200 for a skin care device according to an embodiment of the present invention, flexibility and elasticity can be secured by the substrate part 111 being formed of a porous substrate having flexibility and elasticity. . Accordingly, even if the LED patches 100, 100 ′, 200 for skin care devices according to an embodiment of the present invention are attached to a curved body part such as a face, it can be deformed to fit the curved body part, thereby increasing adhesion with the skin. Can be increased.

In addition, the substrate portion 111 for mounting the LED 112 in the LED patch 100, 100', 200 for a skin care device according to an embodiment of the present invention is formed of a nanofiber web to have a very thin thickness. Therefore, the LED patches 100, 100 ′, 200 for skin care devices according to an embodiment of the present invention may be implemented in a slim shape.

Through this, even if the LED patch (100, 100', 200) for a skin care device according to an embodiment of the present invention is attached to the user's skin through a material such as cosmetics or ampoules, the skin of the user can be applied to an embodiment of the present invention. Accordingly, the possibility of separation of the LED patches 100, 100', 200 for skin care devices may be significantly reduced.

The circuit pattern portions 113 and 113 ′ may be formed in a predetermined pattern on at least one surface of the substrate portion 111, and electronic components mounted on the substrate portion 111 may be electrically connected to each other.

For example, the circuit pattern parts 113 and 113 ′ may be formed of a plurality of patterns that are not electrically connected to each other. Here, a plurality of patterns that are not electrically connected to each other may be electrically connected to each other through an electronic component such as an LED 112 or a temperature sensor 115 mounted on one surface of the substrate part 111.

In addition, the plurality of patterns may be formed linearly as shown in FIGS. 1 to 4, or may be formed in a plane having a predetermined area as shown in FIGS. 5 to 11.

In this case, the circuit pattern portions 113 and 113 ′ may be configured to maintain electrical stability even if the substrate portion 111 is made of a material having elasticity and flexibility.

That is, the circuit pattern portions 113 and 113 ′ may include at least two layers stacked on each other to maintain electrical stability even when the substrate portion 111 is stretched and contracted.

For example, the circuit pattern portions 113 and 113 ′ include first patterns 113a and 113a ′ directly formed on the substrate 111 and the first patterns as shown in FIGS. 4, 8 and 11. The second patterns 113b and 113b' attached to one surface of the (113a, 113a') may be included, and the LED 112 may be mounted on one surface of the second patterns 113b and 113b'.

Specifically, the first patterns 113a and 113a ′ are printed patterns formed directly on the substrate 111 so that a conductive material fills the pores 111b of the substrate 111 as shown in FIG. 14. I can.

That is, the first patterns 113a and 113a ′ may be printed patterns directly formed on the substrate part 111 through a printing method using a conductive paste, and the conductive paste together with the surface of the substrate part 111 The pores 111b formed in the substrate part 111 may be completely filled or partially filled. Here, the conductive paste may be an Ag paste, but is not limited thereto, and all known conductive pastes may be applied.

Further, the second patterns 113b and 113b' may be a conductive microfiber web in which a conductive material (C) is plated on a microfiber web formed so that the microfibers (A) have pores (B). That is, the second patterns 113b and 113b' are formed of a conductive microfiber web plated so that a conductive material (C) surrounds the surface of the microfibers (A) constituting the microfiber web, as shown in FIG. Can be.

Accordingly, the second patterns 113b and 113b' may have elasticity and flexibility similar to the substrate part 111, and when the substrate part 111 is stretched or contracted by an external force, the substrate part ( It can be stretched or contracted in the same way as 111).

In this case, the second patterns 113b and 113b' are formed directly on the substrate 111 from a conductive microfiber web plated so that a conductive material surrounds the surface of the microfibers A constituting the microfiber web. It may be punched to have the same pattern shape as the patterns 113a and 113a'.

Such second patterns 113b and 113b' may be attached to one surface of the first patterns 113a and 113a' through a conductive adhesive layer. Here, the conductive adhesive layer may be an adhesive layer including a vertical conductive filler such as Ni.

Accordingly, the first patterns 113a and 113a' and the second patterns 113b and 113b' may have the same pattern shape, and the first patterns 113a and 113a' and the second patterns 113b, 113b') may be energized to each other through the conductive adhesive layer.

In this way, the LED patches 100, 100', 200 for skin care devices according to an embodiment of the present invention stack the first patterns 113a, 113a' and the second patterns 113b, 113b' formed in different ways. Thus, by configuring the circuit pattern portions 113 and 113 ′, the conduction stability of the circuit pattern portions 113 and 113 ′ can be improved.

That is, when the substrate portion 111 having elasticity and flexibility is stretched or contracted during the use process, the first patterns 113a and 113a' and the second patterns 113b and 113b' formed in different ways are short-circuited. By supplementing, the LED 112 can be stably operated.

If the circuit pattern parts 113 and 113 ′ are composed only of the first patterns 113a and 113a ′ directly formed on the substrate part 111 and the LED 112 is mounted on the first patterns 113a and 113a ′ In this case, if the substrate part 111 is bent or wrinkled by an external force, a crack may occur on the side of the first patterns 113a and 113a'. Accordingly, the LED 112 mounted on the first patterns 113a and 113a' may not be stably supplied with power due to cracks generated in the first patterns 113a and 113a'.

On the other hand, when the circuit pattern portions 113 and 113 ′ are composed of only the second patterns 113b and 113b ′ formed of a conductive microfiber web, and the LED 112 is mounted on the second patterns 113b and 113b ′ If the substrate part 111 is stretched or contracted by an external force, the cross-sectional areas of the second patterns 113b and 113b' may be reduced or increased. Accordingly, the resistance applied to the circuit pattern portion may be varied by changing the cross-sectional area of the second patterns 113b and 113b'. Accordingly, since the resistance applied to the LED 112 is also variable, the LED 112 may not emit uniformly.

In the present invention, the second patterns 113b and 113b' are formed by stacking the first patterns 113a and 113a' and the second patterns 113b and 113b' formed in different ways to form the circuit pattern portions 113 and 113'. ) To reduce the likelihood of an electrical short, and offset a change in resistance through the first patterns 113a and 113a'.

Through this, the LED patches 100, 100 ′ and 200 for skin care devices according to an exemplary embodiment of the present invention may maintain conduction stability of the circuit pattern parts 113 and 113 ′.

Accordingly, the LED patches 100, 100', 200 for skin care devices according to an embodiment of the present invention are reliable because the LEDs 112 mounted on the second patterns 113b and 113b' can be operated stably. Can increase.

In addition, the LED patches 100 ′ and 200 for skin care devices according to an embodiment of the present invention include a first pattern 113a ′ formed in a plane having a predetermined area and a first pattern as shown in FIGS. 5 to 11. When the circuit pattern part 113 ′ is formed by stacking the two patterns 113b ′, the contact area between the first pattern 113a ′ and the second pattern 113b ′ may be increased. Through this, the LED patches 100 ′ and 200 for skin care devices according to the present embodiment may further increase conduction stability.

However, the configuration of the circuit pattern units 113 and 113 ′ in the LED patches 100, 100 ′ and 200 for skin care devices according to an embodiment of the present invention is not limited thereto, and the first patterns 113a and 113a ′ or the second It may be composed of only the patterns 113b and 113b'.

Meanwhile, in the LED patches 100, 100', 200 for skin care devices according to an embodiment of the present invention, the average pores of the microfiber web constituting the second patterns 113b, 113b' are the substrate portion 111. It may have a size relatively larger than the average pore size of the porous substrate.

Through this, when the LED 112 is mounted on the second patterns 113b and 113b', the solder paste for mounting the LED 112 is conductive microfibers constituting the second patterns 113b and 113b'. While sufficiently penetrating the pores B of the web, it may not penetrate into the pores 111b of the substrate portion 111 on which the first patterns 113a and 113a' are formed.

For this reason, the LED 112 mounted on the second patterns 113b and 113b' can form a strong bond with the second patterns 113b and 113b' through a solder paste.

As an example, the average pores of the microfiber web constituting the second patterns 113b and 113b' may be 5 to 15 μm, and the average pores of the substrate part 111 may be 0.1 to 2 μm. However, the size of the average pores is not limited thereto, and if the average pores of the microfiber web constituting the second patterns 113b and 113b' have a relatively larger size than the average pores of the substrate portion 111 It can be appropriately changed according to design conditions.

When the LED 112 is supplied with power, the LED 112 may generate light having a predetermined wavelength band.

One or more such LEDs 112 may be provided, and preferably, a plurality of LEDs 112 may be provided to form a surface light source. In addition, the plurality of LEDs 112 may be spaced apart from each other.

Through this, in the LED patches 100, 100', 200 for skin care devices according to an embodiment of the present invention, a plurality of LEDs 112 are disposed in a form dispersed on one surface of the plate-shaped substrate portion 111 to generate a surface light source. Can be implemented. For this reason, the LED patches 100, 100 ′, 200 for skin care devices according to an embodiment of the present invention can irradiate light onto the user's skin over a large area.

In this case, the LED 112 may emit light with one wavelength band. For example, the LED 112 may destroy bacteria and treat acne by emitting light in the 405 to 420 nm band that can be absorbed by the skin epithelial tissue.

However, the wavelength band of the LED 112 is not limited thereto, and the LED 112 may irradiate light in a selected arbitrary wavelength band suitable for a desired skin improvement effect among the 405 to 970 nm band.

In addition, the LED 112 may irradiate one wavelength band, but may be provided to irradiate light in different wavelength bands. As a non-limiting example, the LED 112 may be integrally formed with a plurality of light emitting devices that irradiate light of different wavelength bands. Alternatively, the LED 112 may be composed of a plurality of LEDs, and the plurality of LEDs may be composed of two or more LEDs that irradiate light of different wavelength bands.

Meanwhile, the light source unit 110 may further include at least one temperature sensor 115 mounted on one surface of the substrate unit 111. The temperature sensor 115 may measure the temperature generated when the LED 112 emits light.

Here, the temperature sensors 115 may be mounted on one surface of the substrate 111 in an appropriate number, and may be distributedly arranged to measure temperatures at various locations.

The cover part 120 may cover at least one surface of the substrate part 111. As an example, the cover part 120 may be provided on at least one surface of the substrate part 111 to surround the light source parts 110 and 110 ′.

Through this, the cover unit 120 can prevent external exposure of the light source units 110 and 110 ′, and block a liquid substance such as moisture applied to the user's skin from moving toward the light source unit 110 and 110 ′. have.

To this end, the cover part 120 may be a plate-shaped sheet having a predetermined area so as to cover the light source parts 110 and 110 ′.

Such a cover 120 may be made of a material such as a polymer resin such as PU, PET, PP, PE, PVDF, release paper, fabric, leather, etc., and may be made of a molding body covered by a resin material made of an insulator.

In addition, the cover part 120 may be made of a silicon material.

Here, when the cover part 120 is made of a silicon material, the cover part forming a contact surface in contact with the user's skin may have a hardness of 5-20.

Typically, silicones with a hardness of 5-20 can have a very sticky surface. In the present invention, the cover part that forms the contact surface in contact with the user's skin is composed of a silicone material having a hardness of 5 to 20, so that even if a liquid or gel material such as a separate adhesive, adhesive, ampoule, essence, or cosmetic is not used, Can be attached directly.

Meanwhile, the cover part 120 may be made of a material having flexibility and flexibility. In addition, the cover unit 120 may be made of a material having flexibility and flexibility and moisture-proof properties so as to block the movement of moisture.

As a specific example, the cover unit 120 may include a pair of cover members 121 and 122 as shown in Figs. 1, 5, and 9, and the pair of cover members 121 and 122 is the substrate It may include a first cover member 121 and a second cover member 122 respectively disposed on both sides of the portion 111.

The first cover member 121 and the second cover member 122 may be attached via an adhesive layer or fixed to each other through heat fusion. Here, the adhesive layer may be a liquid or gel inorganic material type, or may be a substrate type in which an adhesive material is applied to both surfaces of the substrate.

In addition, the first cover member 121 may be a cover member covering one surface of the substrate portion 111 on which the LED 112 is mounted, and the second cover member 122 includes the LED 112 It may be a cover member covering one surface of the substrate portion 111 that is not. In this case, the outer surface of the first cover member 121 may be a contact surface that contacts the user's skin.

In this case, the LED patches 100 and 100 ′ for skin care devices according to an embodiment of the present invention may be configured to limit the irradiation direction of light generated from the LED 112. In addition, the LED patch for a skin care device according to an embodiment of the present invention (100, 100') scatters or diffuses the light generated from the LED 112, which is a point light source, so that the light generated from the LED 112 It can be released to the outside in a form.

That is, the first cover member 121 may have a translucent property to transmit light, and the second cover member 122 may have a translucent or opaque property to block the passage of light. In addition, the first cover member 121 may include a light diffusion material such as TiO ₂ .
