Description

Luminous mask {LUMINOUS MASK}

The present invention relates to a light emitting mask, and more particularly, to a light emitting mask that can easily control the diffusion and concentration of light.

In general, a light emitting mask using a light source is used to improve skin such as wrinkle improvement, skin regeneration, and inflammation treatment by irradiating light generated from the light source to the user's skin.

Alternatively, after applying a photosensitive cosmetic material, which is chemically reacted by light, to the skin, a light sensitive mask is worn to make the photosensitive cosmetic material react to light. Through this, the photosensitive cosmetic material was allowed to react with light generated from the light emitting mask, thereby improving the skin of the user.

The conventional light emitting mask is a method in which a plurality of light sources are attached to a surface facing a user's skin, and then light emitted from the light source is directly irradiated to the skin. For this reason, the production cost has increased as additional light sources are provided, and the amount of heat energy generated from the light sources increases, so that a user may be injured by a low-temperature burn.

In addition, the existing luminous mask does not have a configuration that concentrates light in areas that require intensive management, such as the T-zone including the nose and eyebrows, or the butterfly zone containing the skin around the cheekbones. There was a problem that the light must be concentrated and irradiated.

The present invention can be implemented in many 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 attached to the same or similar elements throughout the specification.

1 is an exploded perspective view of a light emitting mask according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view showing a first modification of the light emitting mask shown in FIG. 1.

1 and 2, the light emitting mask 1 according to an embodiment of the present invention may include a first body part 10, a light emitting part 30, and a second body part 50.

In one embodiment of the present invention, the first body portion 10 may be formed in a curved shape corresponding to a protruding portion of the face such as a cheekbone, a chin, or forehead so as to surround the outer surface of the face. At this time, the first body portion 10 may be made of a non-transmissive material to prevent light emitted from the light emitting portion 30 from flowing out.

To this end, the first body portion 10 may be made of a polymer compound material such as polystyrene, polyethylene, or polycarbonate. Such a polymer compound has strong durability and is relatively light, so that a user can easily handle the light emitting mask 1 according to an embodiment of the present invention.

On the other hand, the first body portion 10 may be formed with an eye opening 11 on a surface in contact with the user's eye. The eye opening 11 prevents a user's field of view restriction using the light emitting mask 1 according to an embodiment of the present invention, and prevents the user's eyeball from being directly exposed to light generated by the light emitting unit 30. Can.

In addition, the first body portion 10 may be formed with a protrusion 15 that protrudes in a direction opposite to the direction of the user's face in the portion where the user's nose is located. The user may place the nose in the placement space 16 in which the protrusion 15 protrudes and is formed, so that the light emitting mask 1 according to an embodiment of the present invention is in close contact with the face.

Meanwhile, in an embodiment of the present invention, the light emitting unit 30 may be located on a surface facing the user's face of the first body unit 10, for example, on the inner surface of the first body unit 10. At this time, one or more light sources 35 may be provided in the light emitting unit.

The light source 35 may be disposed in correspondence with a skin location requiring intensive management, such as a T zone including skin between the user's eyebrows and the upper part of the nose or a butterfly zone including skin where the user's cheekbone is located. Can.

Through this, the light-emitting mask 1 according to an embodiment of the present invention can arrange a light source 35 on a skin area that needs to be managed, so that light can be irradiated to an area that requires intensive management.

Meanwhile, the light emitting unit 30 may be connected to the control unit 60. In one embodiment of the present invention, the control unit 60 may supply power to the light sources 35 of each light emitting unit 30, and may also adjust the amount of power supplied to the light sources 35.

The user may control the intensity of light generated by the light source 35 by operating the control unit 60 to adjust the amount of power supplied to the light source 35. In addition, by selectively emitting only the light source 35 located at a specific location, for example, the T zone or the butterfly zone, light can be intensively irradiated to a specific area of the user's skin.

As another example, the control unit 60 may be composed of a battery that supplies power and a timer circuit that passes current only for a certain period of time. In this case, the current generated in the battery moves to the light source 35 through a timer circuit. At this time, the timer circuit can supply a current to the light source 35 only for a certain time after operation, so that the user's skin can be irradiated only for a certain time.

Through this, the light emitting mask 1 can control the intensity of light generated from the light source 35, the skin region to which light is irradiated, and the time at which light is irradiated.

The light source 35 may be formed of, for example, a light emitting diode (LED). The light emitting diode generates less heat compared to the intensity of light generated, and thus, even if it is irradiated to the skin for a long period of time, it can prevent a user from being injured, such as a low temperature burn.

3 is a cross-sectional view of the light emitting mask shown in FIG. 2.

Referring to FIG. 3, in one embodiment of the present invention, the light source 35 may be combined with the substrate member 31 seated on the inner surface of the first body portion 10. In addition, the substrate member 31 may be formed of a conductive member 33 coated with a metal patterned on one side. The light source 35 is connected to the conductive member 33 formed on the substrate member 31, and may emit light with power supplied from the control unit 60 through the conductive member 33.

At this time, in one embodiment of the present invention, the substrate member 31 may be formed of a flexible substrate having elasticity. For example, the substrate member 31 may be formed of a flexible printed circuit board (FPCB) on which a conductive member 33 such as copper is printed.

That is, since the substrate member 31 is made of an elastic material, the substrate member 31 is bent by bending on the inner surface of the first body portion 10 formed to correspond to the user's face flexion, and the first body It can be in close contact with the part 10.

Through this, in one embodiment of the present invention, the light emitting part 30 is in close contact with the first body part 10 so that the user's skin and the light emitting mask 1 according to an embodiment of the present invention can be in close contact with each other. can do.

Meanwhile, referring to FIG. 3, the light emitting unit 30 may include a reflective member 37 formed between the plurality of light sources 35.

The reflective member 37 may be composed of a metal plate deposited or printed on the polished metal plate or substrate member 31 to reflect light. That is, the reflective member 37 reflects light traveling in a direction different from the user's skin direction among the light generated from the light source 35, so that it can proceed in the user's face direction.

Through this, the light emitting mask 1 according to an embodiment of the present invention can improve the efficiency of the light source 35 by increasing the amount of light irradiated to the user's face by adjusting the path of light to the reflective member 37. Can.

Meanwhile, referring to FIGS. 1 and 2, in an embodiment of the present invention, the second body portion 50 is positioned to cover the surfaces of the light emitting portion 30 and the first body portion 10 facing the user's face. can do.

In addition, the second body portion 50 is in direct contact with the cosmetic applied to the user's face and face, and has high chemical resistance and durability, such as polystyrene, polyethylene, and polycarbonate. It may be composed of a compound material.

At this time, the second body portion 50 may be made of a transmissive or semi-transmissive material capable of passing light. Light passing through the second body portion 50 may interact with particles constituting the second body portion 50 and be scattered. Through this, the second body portion 50 may be configured to transmit and scatter light generated from the light source 35 to reach the user's skin.

In addition, paint may be added to the second body portion 50 during the manufacturing process. That is, by adding a paint having a specific color to the second body portion, the second body portion 50 is selectively irradiated to the skin only the light of a specific wavelength band corresponding to the photosensitive cosmetic applied by the user, the work of the present invention The efficiency of the light emitting mask 1 according to the embodiment can be improved.

On the other hand, the second body portion 50 is positioned adjacent to the placement space 16, for example, the support protrusion 61 and the support protrusion protruding in the direction of the user's face on the left and right sides of the surface contacting the placement space 16 It may include a support member 63 is provided to be fitted to the (61). As another example, the support member 63 is formed to protrude on the surface of the second body portion 50 in contact with the arrangement space 16, and may be integrally provided with the second body portion 50.

When the user wears the light emitting mask 1, the support member 63 comes into contact with the left and right side surfaces of the user's nose. The support member 63 in contact with the nose presses the nose and supports the second body portion 50 to fix the position of the light emitting mask 1 according to an embodiment of the present invention. Through this, it is possible to prevent the light emitting mask 1 from deviating from the intended position.

Meanwhile, as illustrated in FIG. 1, the second body part 50 may have a transmission hole 55 formed on a surface of the light emitting part 30 that is in contact with the light source 35.

As shown in FIG. 3, some of the light L generated from the light source 35 is directly or reflected by the reflection member 37 one or more times and passes through the transmission hole 55. That is, the light L passing through the transmission hole 55 is not scattered by the second body portion 50, but proceeds directly toward the user's skin.

At this time, in one embodiment of the present invention, the transmission hole 55 may correspond to a plurality of light sources 35 and may be configured in a plurality. For example, a light emitting mask according to an embodiment of the present invention is configured by directly constructing a plurality of transmission holes 55 on skin requiring intensive management, such as a T zone or a butterfly zone, to directly irradiate light than other parts ( The efficiency of 1) can be increased.

Through this, the light emitting mask 1 according to an embodiment of the present invention allows the light L to pass through the transmission hole 55 directly without passing through the second body portion 50, thereby improving efficiency according to light irradiation. Can be increased.

4 is a cross-sectional view showing a second modified example of the light emitting mask shown in FIG. 2.

Referring to FIG. 4, the cross-sectional area of the transmissive hole 55 in the width direction may gradually increase from a surface contacting the light source 35 toward a surface facing the user's face.

The light L generated from the light source 35 proceeds in the form of a wave and passes through the transmission hole 55. At this time, at the end of the transmission hole 55, the light L diffuses around the end of the transmission hole 55 and a diffraction phenomenon occurs.

That is, the light L at the end of the transmission hole 55 is not straight, but diffracted and diffused around the transmission hole 55. That is, the diffracted light (L) is diffused and irradiated not only on the skin facing the light emitting unit 30, but also around it.

At this time, the degree of diffraction of light L due to the transmission hole 55 is inversely proportional to the size of the cross-sectional area of the transmission hole 55. That is, if the cross-sectional area in the width direction of the transmission hole 55 is large, the degree of diffraction of the light L may be small. Conversely, if the cross-sectional area in the width direction of the transmission hole 55 is small, the degree of diffraction of the light L may be increased.

In one embodiment of the present invention, the second body portion 50 configures the cross-sectional area of the transmission hole 55 toward the user's skin from the light source 35 toward the skin, thereby minimizing the degree of diffraction of the light L Thus, the light L can be irradiated to the skin requiring intensive irradiation such as the butterfly zone or the T zone.

Through this, the light emitting mask 1 according to an embodiment of the present invention can change the cross-sectional area of the transmission hole 55 to control the amount of light L that is intensively irradiated to a position in need of management.

5 is a cross-sectional view showing a third modified example of the light emitting mask shown in FIG. 2.

Referring to FIG. 5, in an embodiment of the present invention, the second body portion 50 may further include a diffusion member 51 formed at a position in contact with the light source 35.

The diffusion member 51 is, for example, formed in a plate shape, one side of which is coupled to the second body portion 50, and a plurality of diffusion protrusions on the opposite side of the surface that is coupled to the second body portion 50 ( 52) may be formed protruding.

The plurality of diffusion protrusions 52 are formed so that the diffusion member 51 generated from the light source 35 refracts the path of the light L from the light source 35 toward the skin, so that the light L is the diffusion member 51 ).

At this time, the degree of diffusion of the light L may be configured differently according to the protruding degree of the diffusion protrusion 52. If the protruding degree of the diffusion protrusion 52 is large, the degree of diffusion of the light L becomes large. Conversely, if the protruding degree of the diffusion member 51 is configured to be small, the degree to which the light L diffuses becomes small.

Through this, the light emitting mask 1 according to an embodiment of the present invention may irradiate the light L to a wide area of the user's face by refracting the light L with the diffusion member 51.

Meanwhile, the cross-sectional area of the diffusion member 51 on which the diffusion protrusion 52 is formed may be formed to be larger than the cross-sectional area of the light source 35. That is, the light generated by the light source 35, as well as the light of the diffusion member 51, the light generated by the light source 35 or reflected or refracted by the reflective member 37 or the second body portion 50, etc. also diffuse member ( 51).

Through this, the diffusion member 51 can improve the efficiency of diffusion by allowing not only the light source 35 but also the light refracted or reflected around the light source 35 to diffuse.

6 is a cross-sectional view showing a first modification of the diffusion member shown in FIG. 5.

Referring to FIG. 6, the second body portion 50 may have the diffusion member 51 and the transmission hole 55 at the same time.

In addition, the diffusion member 51 may further include a first fitting member 53.

The first fitting member 53 may be formed to protrude on a surface opposite to the surface on which the diffusion protrusions 52 of the diffusion member 51 are formed. At this time, the shape and cross-sectional area of the cross section in the width direction of the first fitting member 53 may correspond to the shape and cross-sectional area of the cross-section in the width direction of the transmission hole 55.

For example, as shown in FIG. 6, the diffusion member 51 has the same cross-sectional shape and cross-sectional area of the first fitting member 53 as the cross-sectional shape and cross-sectional area of the transmissive hole 55. By configuring, the diffusion member 51 may be coupled to the second body portion 50 through the fitting engagement in which the first fitting member 53 is fitted into the transmission hole 55.

As shown in FIG. 6, the second body portion 50 diffuses the light generated from the light source 35 by fitting the diffusion member 51 to the transmission hole 55, or is mounted to the transmission hole 55 By removing the diffused member 51 from the transmission hole 55, the method of applying the light can be easily adjusted by directly irradiating the light generated from the light source 35.

For example, when the area to which light is to be irradiated, such as the user's forehead or chin, is wide, the user spreads the light generated in the light source 35 by inserting the diffusion member 51 in the transmission hole 55 to irradiate the wide area It can be done. Conversely, in a region where it is necessary to intensively irradiate light such as a T zone or a butterfly zone, the diffusion member 51 may be removed from the transmission hole 55 so that light can be directly irradiated.

Through this, in one embodiment of the present invention, the light emitting mask 1 may select the diffusion or direct irradiation of light generated from the light source 35 through the transmission hole 55 and the diffusion member 51 as necessary.

At this time, the cross-sectional area of the first fitting member 53 in the width direction, that is, the cross-sectional area of the transmission hole 55 may be formed smaller than the cross-sectional area of the diffusion member 51.

The light generated from the light source 35 is not only light directed to the transmission hole 55 directly from the light source 35, but also light that is refracted or reflected in the second body portion 50 or reflected by the reflection member 37.

Therefore, the cross-sectional area of the diffusion member 51 is configured to be larger than the cross-sectional area of the transmission hole 55 and the first fitting member 53, so that the light passing through the transmission hole 55 as well as the reflection member 37 or the second body Light reflected or refracted by the unit 50 may also be configured to diffuse.

Meanwhile, referring to FIG. 6, the second body portion 50 may further include a light collecting member 57. In addition, the light collecting member 57 may include a light collecting lens 58 and a second fitting member 59.

The condenser lens 58 may be positioned at an end of the transmission hole 55 adjacent to the light source 35. In addition, the condenser lens 58 may be configured in a hemisphere shape in which the curved surface faces the user's face and the flat surface faces the transmission hole 55 and the light source 35.

As shown in FIG. 6, the hemisphere-shaped condensing lens 58 may collect light by refracting the light L generated from the light source 35. At this time, the focus of the condensed light L may correspond to the curvature of the curved surface of the condensing lens 58.

For example, as the curvature of the condenser lens 58 increases, the focus, which is the position where the light L is converged, is directed toward the condenser lens 58 and the light source 35. Conversely, when the curvature of the condensing lens 58 is small, the focus at which the light L is converged is directed to the opposite direction of the light source 35 and the condensing lens 58, that is, toward the user's skin.

That is, in the process of manufacturing the light collecting member 57, while wearing the light emitting mask 1, the distance between the second body portion 50 and the user's face is measured, and accordingly the curvature of the light collecting lens 58 is adjusted. By doing so, the light L passing through the light collecting member 57 can be focused on the skin.

Through this, in one embodiment of the present invention, the light emitting mask 1 can be irradiated by condensing the light L to an area requiring intensive irradiation of light, such as a butterfly zone or a T zone, through the light collecting member 57. .

The second fitting member 59 may be formed to protrude from the surface toward the light source 35 of the condenser lens 58. At this time, the shape and cross-sectional area of the cross-section in the width direction of the second fitting member 59 may correspond to the cross-sectional shape and cross-sectional area of the transmissive hole 55.

For example, as shown in FIG. 6, the shape and cross-sectional area of the cross-section in the width direction of the second fitting member 59 are configured to be the same as the cross-sectional shape and cross-sectional area of the transmissive hole 55, and the second The light collecting member 57 may be coupled to the second body portion 50 through the fitting coupling in which the fitting member 59 is fitted into the transmission hole 55.

At this time, the cross-sectional area of the second fitting member 59 in the width direction, that is, the cross-sectional area of the transmission hole 55 may be formed to be smaller than the cross-sectional area of the light collecting member 57.

The light generated from the light source 35 is not only light directed to the transmission hole 55 directly from the light source 35, but also light that is refracted or reflected in the second body portion 50 or reflected by the reflection member 37.

Therefore, the cross-sectional area of the light collecting member 57 is configured to be larger than the cross-sectional area of the transmission hole 55 and the second fitting member 59, so that not only the light passing through the transmission hole 55, but also the reflection member 37 or the second body Light reflected or refracted by the unit 50 may also be configured to be condensed.

7 is a cross-sectional view showing a second modification of the diffusion member and the light collecting member shown in FIG. 5.

Referring to FIG. 7, the light collecting member 57 or the diffusion member 51 of the light emitting mask 1 may be configured to cover the plurality of transmission holes 55.

The first fitting member 53 or the second fitting member 59 may be combined with the second body portion 50 by fitting the transmission hole 55.

The diffusion member 51 covering the plurality of transmission holes 55 may diffuse light generated from the plurality of light sources 35 and proceed to collectively, so that light is irradiated to a wide area of the face. In addition, the light collecting member 57 covering the plurality of transmission holes 55 can collectively collect light generated from the plurality of light sources 35 to irradiate light to the skin.

That is, the diffusion member 51 or the light collecting member 57 is configured to cover the plurality of transmission holes 55 without the need to manufacture the diffusion member 51 or the light collecting member 57 to correspond to the respective transmission holes 55 Thus, the user can be configured to easily separate or combine the diffusion member 51 or the light collecting member 57 from the second body portion 50.

In addition, the risk of loss during use is less than that of the diffusion member 51 or the light collecting member 57, which is made to correspond to each transmission hole 55 by making the diffusion member 51 or the light collecting member 57 large. Can.

Through this, the diffusion member 51 or the light collecting member 57 is configured to cover the plurality of light sources 35 and the transmission hole 55, thereby improving convenience of use.
