To increase skin elasticity and skin care such as acne treatment, massage creams or acne treatment cosmetics are used. However, there are limitations in performing skin care using cosmetics, especially for people living in urban areas with severe air pollution. Therefore, many devices for skin care have been developed and used. Recently, devices for treating skin diseases such as acne, pores, blackheads, and excessive sebum have been introduced to depilate arms, legs, armpits, forehead, and under the nose through laser.

Phototherapy for the treatment of such skin diseases is based on the fact that light promotes biochemical reactions within the skin, and is damaged through regeneration or destruction of skin tissue using various light sources such as sunlight, laser, fluorescent lamp, and UV lamp.

The embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described below. The present embodiments are provided to explain the present invention in more detail to those of ordinary skill in the art to which the present invention pertains.

1 is a perspective view of a photon therapy mask device having a wavelength tunable function according to an embodiment of the present invention. As shown in FIG. 1, a photon therapy mask apparatus according to an embodiment of the present invention can be largely divided into a mask unit (A) and a controller (B).

The mask part A is configured to correspond to the shape of a person's face as a whole, and a light emitting sheet 2 equipped with a wavelength changeable LED module 2'is installed therein. Accordingly, phototherapy can be performed with output light of an appropriate wavelength band by user manipulation. A specific configuration of the mask portion A will be described with reference to FIG. 2.

The controller B, as a power supply unit, is a device for supplying power to the mask unit A and generating an input signal for causing the mask unit A to operate properly. The controller B is provided with a user input unit that generates a selection signal capable of treating various types of skin diseases.

Hereinafter, the mask part A will be described in more detail with reference to FIG. 2.

2 is an exploded perspective view of a mask portion (A) of a photon therapy mask device having a wavelength tunable function according to an embodiment of the present invention. As shown in Fig. 2, the mask portion (A) of the photon therapy mask device according to an embodiment of the present invention includes an outer face cover 11, a light emitting sheet 2, an inner face cover 12, and an inner support. It may be configured to include (14) and an outer support (15).

The outer face cover 11 and the inner face cover 12 represent the overall shape of the mask portion (A). The outer face cover 11 may be made of an opaque material, and may be made of a synthetic resin material made of a flexible material. The inner face cover 12 is a component facing the user's face and may be made of a transparent material. A plurality of circular wrinkles are formed on the face cover, and the output light emitted from the light emitting sheet 2 may be refracted and scattered to irradiate uniform light to the skin. In addition, since a silicone coating layer having low thermal conductivity is applied to the face side of the face cover, it may be configured to prevent a user from getting burned by the light emitting sheet 2 in advance. Alternatively, the face cover is configured such that a transmission hole is formed at a position corresponding to the LED module 2', which is a component of the light emitting sheet 2, so that the light output from the LED module 2'is directly irradiated to the user's skin. May be.

The face cover has an eye through hole 13, a nose through hole 13 ′, and an mouth through hole 13 ″ so that the wearer can comfortably wear the mask device while receiving phototherapy.

A configuration including the outer face cover 11 and the inner face cover 12 is referred to as a face cover (1).

These light-emitting sheets 2, the inner cover and the inner cover are supported by the inner support 14 and the outer support 15.

The outer support 15 is formed on the outer edge of the mask part A to support the face cover and the light-emitting sheet 2, and the inner support 14 has an eye penetration hole 13 and a nose penetration hole. (13'), formed in an oval shape in the entrance hole 13", to support the face cover 1 and the light emitting sheet 2 together with the outer support 15. Here, the outer support 15 and the inner supporter ( 14) has the same thickness and has a shape that supports the light emitting sheet 2 and the face cover from both sides, so that the inner face cover 12 of the face cover 1 can be configured to be spaced apart so that it does not directly touch the face. have.

The light-emitting sheet 2 has a form in which a plurality of matrix-shaped LED modules 2'are attached to the sheet. The sheet is made of a soft material, is formed on a metal pattern layer thereon, and the LED modules 2 ′ are installed on the metal pattern layer so as to be independently controlled. The LED module 2'may be installed more densely around the nose and both cheeks where skin troubles occur.

Although the LED module 2'will be described with reference to FIGS. 3 and 4, as the piezoelectric element 22 is provided and power is supplied to the piezoelectric element 22, the piezoelectric element 22 is physically deformed. Accordingly, the wavelength band of the output light of the LED module 2'is also changed. This will be described in more detail in FIGS. 3 and 4.

3 is a cross-sectional view of a tunable LED module 2'according to another embodiment of the present invention. As shown in FIG. 3, the tunable LED module 2'is composed of a lead frame 21, a piezoelectric element 22, an LED chip 23, and an encapsulant 24.

The lead frame 21 forms the outer shape of the LED module 2', and a cup portion for installing the LED chip 23 is formed therein.

A piezoelectric element 22 and an LED chip 23 are installed in the cup portion.

The piezoelectric element 22 is an element whose shape changes according to the supply of electricity. In other words, the piezoelectric element 22 is an element using crystals or piezoelectric ceramics, etc., in which a voltage is generated when mechanical stress is applied and distortion occurs when a voltage is applied on the contrary. It refers to a device that expands or contracts when is applied. It is attached to the bottom of the cup portion of the lead frame 21 and is connected to a wire (not shown) to generate a mechanical stress to which a voltage is supplied. Here, the piezoelectric element 22 has a surface area larger than the surface area of the LED chip 23 as shown, so that mechanical stress is sufficiently transmitted to the LED chip 23.

The LED chip 23 is disposed on the piezoelectric element 22 as a component for irradiating output light. Accordingly, when a mechanical stress is generated in the piezoelectric element 22, the LED chip 23 receives the stress accordingly, thereby changing the output light.

Here, the LED chip 23 may have an output wavelength of at least one of 390nm, 450nm, 580nm, 630nm, 700nm.

For example, when the basic output light value is 630 nm, the wavelength of the output light of 630 ± 40 nm is changed according to the mechanical stress value of the piezoelectric element 22. For example, in the case of acne, the effective wavelength may be 415nm and 630nm, but depending on the person, the effective wavelength may be 405nm or 415nm, the effective wavelength for atopic dermatitis may be 617nm and 645nm, and in the case of erythema, the effective wavelength may be 595nm. For example, when the basic output wavelength of the LED chip 23 is set to 630 nm, an appropriate treatment is basically performed for acne, but an appropriate treatment is not performed for atopic dermatitis. Accordingly, in the present invention, by applying a voltage to the piezoelectric element 22, the output wavelength can be changed to 617 nm and 645 nm, and accordingly, not only acne but also atopy in the photon therapy mask device composed of one type of LED chip 23 You can expect a good treatment effect for dermatitis. In addition, since a plurality of LED chips 23 are independently controlled, it is possible to configure to simultaneously output light of different wavelengths, respectively, if necessary.

The encapsulant 24 is a component covering the cup portion of the lead frame 21 and is a component for protecting the LED chip 23. Since the encapsulant 24 contains a phosphor, it is possible to change the wavelength band of the output light generated from the LED chip 23. In this case, the output light emitted from the LED chip 23 may be changed firstly by the piezoelectric element 22 and secondly changed by the encapsulant 24.

Hereinafter, another embodiment of the tunable LED module 2'will be described with reference to FIG. 4.

4 is a diagram showing another embodiment of a tunable LED module 2', which is another embodiment of the present invention. In another embodiment of the tunable LED module 2 ′ illustrated in FIG. 4, the piezoelectric element 22 is, unlike the embodiment of FIG. 3, the piezoelectric element 22 is a plurality of strip-shaped sub-piezoelectric elements installed side by side. Consisting of 221, the LED chip 23 is installed in the form of a bridge on the sub-piezoelectric element 221. By configuring in this way, it is possible to transmit more stress of the piezoelectric element 22 to the LED chip 23, and accordingly, more wavelength shift occurs. When configured with four sub-piezoelectric elements 221 as shown in FIG. 4, wavelength shifting up to ±80 nm is possible.

According to an embodiment of the present invention having the above-described configuration, by changing the shape of the LED chip using a piezoelectric element, the output wavelength is changed, and accordingly, output light of a required wavelength band can be obtained.

In addition, according to an embodiment of the present invention, it is possible to output various types of wavelength bands from the same LED chip, so that the best light therapy can be provided when there are different types of skin problems for each location.
