In another example, each light source array section 31-36 may include at least two light sources, such as at least one light emitting diode and at least one laser diode.

Each of the light source array units 31-36 includes at least one light emitting diode such as a red light emitting diode, a green light emitting diode, a blue light emitting diode, a yellow light emitting diode, and an infrared light emitting diode. At this time, the type of the light emitting diode used in each of the light source array units 31-36 can be changed depending on the treatment purpose, the skin condition of the user, and the like.

The operation state of the ventilation fan 37 changes according to the control signal output from the control unit 20. [

In this example, the operation state of the ventilation fan 37 is controlled according to the value of the internal humidity of the light irradiation skin management apparatus measured by the humidity amount sensing section 15. [

The ventilation fan 37 has a motor (not shown) that rotates the ventilation fan 37 according to a control signal output from the control unit 20. [

2 and 3, the light irradiation skin management apparatus includes a main body 100, a pedestal 300, and a connection part 200 for connecting the main body 100 and the pedestal 300.

The main body 100 has a predetermined thickness and its shape is designed based on the shape of a person's face so that the entire face of the user is located. Thus, the face of the person is easily and conveniently located in the main body 100. The main body 100 may have a hollow semi-elliptical shape.

The main body 100 includes a forehead support 51 protruding from a bottom surface of the main body 100 at a position where a user's forehead is located, that is, an upper end of the main body 100, A jaw support 52 protruding from the bottom surface of the main body 100 and located at the lower end of the main body 100 (i.e., a portion positioned on the opposite side of the upper end) And a blindfold 60 located at the center of the portion (i.e., between the upper and lower ends) and protruding from the bottom surface of the main body 100.

 The forehead support 51 supports the user's forehead and the jaw support 52 supports the user's jaw so that the user conveniently places his or her face within the body 100. [

And an ergonomic shape of an ergonomic design such as a curved shape of the surface of the forehead support 51 and the surface of the jaw support 52 which are in contact with the forehead and jaw of the user. Therefore, the convenience of the user is further improved.

The forehead support 51 and the jaw support 52 may be made of urethane or silicon.

The blindfold 60 blocks the light output from the first through sixth light source array units 31-36 to the user's eye to protect the user's eyes from the light and prevent the eyeshadow phenomenon.

3, the blindfold 60 has a protruding portion 61 projecting from the bottom surface of the main body 100 and a blindfold portion 62 connected to the protruding portion 61. [

The protruding portion 61 has a bar shape, and the blindfold portion 62 has a shape elongated in the transverse direction in consideration of the positions of both eyes positioned so as to be spaced apart from each other in the lateral direction in the human face. At this time, the blindfold portion 62 may have a rectangular shape or an elliptical shape.

The surface of the blindfold portion 62, which is in contact with the eyelid such that the user's eyes are positioned more comfortably on the blindfold portion 62, such as the forehead support stand 51 and the jaw support stand 52, has an ergonomic shape, .

At this time, when the user's eyelids come into direct contact with the blindfold portion 62, the user's inconvenience occurs due to the pressure caused by the blindfold portion 62, so that the face of the blindfold portion 62 and the eyelid are separated from each other by a predetermined distance have. Therefore, the blindfold portion 62 may have a structure in which only the edge portion of the blindfold portion 62 is in contact with the peripheral portion of the user's eyes.

The blindfold 60 may be made of silicon or urethane.

Since the forehead support 51 and the chin support 52 are located on the body 100, the eye blind 60 alone can reduce the pain and discomfort of the eyeball that may be felt during or after use, .

The main body 100 also has a plurality of ventilation openings 71-73 for controlling the user's breathing and humidity. At this time, the plurality of ventilation openings 71-73 are openings passing through the main body 100, and the forming position may be located at a portion where the nostrils and a mouth are located.

Thus, during the use of the light irradiation skin management apparatus, the humidity due to the user's breathing and the temperature increase due to the user's breathing and the heat generated during the operation of the light irradiation skin care apparatus are prevented.

Each of the ventilation openings 71-73 has a circular cross-sectional shape, but it is not limited thereto and a plurality of ventilation openings 71-73 having various shapes such as an elliptical shape and at least two mutually-shaped shapes can be located .

In addition, the number of the plurality of vent holes 71-73 and the forming position can be changed as necessary.

As shown in FIG. 2, a plurality of light source array units 31-36 are disposed on the body 100 so as to be spaced apart from each other.

At this time, the plurality of light emitting diodes located in the light source array units 31-36 are exposed to the outside, so that light output from each light emitting diode is output more stably and efficiently to the user's skin without loss.

The positions of the light source array units 31-36 are formed between the forehead support 51 and the blindfold 60 as well as between the blindfold 60 and the jaw support 52 as well as between the sides of the blindfold 60 (100).

Between the blindfold 60 and the chin support 52, the light source array units 32, 33, and 36 are spaced apart from each other in the lateral direction of the face so as to form a part corresponding to the user's nose, Lt; / RTI >

Light emitted from the light emitting diode is irradiated to the forehead portion, the cheek portion, the nose portion, the side portion of both eyes by the plurality of light source array portions 31-36, and light of the light emitting diode is irradiated to the entire face. As a result, portions where no light is irradiated do not occur.

The plurality of light emitting diodes arranged on the light source array units 31-36 are arranged in a matrix structure and arranged in a rectangular shape such as a rectangle. However, the light source array units 31-36 may be arranged at positions Accordingly, a plurality of light emitting diodes can be arranged in various shapes such as a circle or an ellipse.

However, the number of the plurality of light source array units 31-36, the arrangement position, the arrangement of the light emitting diodes, and the like can be efficiently and uniformly irradiated to the whole face of the user in consideration of the divergence angle of each light emitting diode .

As described above, one light emitting diode for emitting a single light or at least two kinds of light emitting diodes for outputting light having at least two different wavelengths may be used for each light source array unit 31-36.

The first through third reflectance sensing units 11-13 may be located at positions where the first through third light source array units 31-33 are located. As described above, the first through third light source array units 31 -36) and detects the amount of reflection of light reflected by the skin of the user, respectively, and outputs a signal of a corresponding size. Each reflection sensing unit 11-13 may be a photo sensor.

The drive switch 17 may be located at the protrusion 61 of the blindfold 60.

The driving switch 17 is turned on when the user pushes the blindfold 60 toward the bottom surface of the main body 100 and is turned off when the user further pushes the blindfold 60 toward the bottom surface of the main body 100, And outputs a corresponding signal.

Alternatively, the drive switch 17 may be turned on when a user moves the blindfold portion 62 to a predetermined position on the bottom surface side of the main body 100 by using an elastic member such as a spring or the like, And may be structured such that it is turned off when the portion 62 moves to the opposite side of the bottom surface and goes out of the predetermined position.

A part of the protruding portion 61 of the blindfold 60 moves to the opposite side of the main body 100 and the opposite direction as shown by an arrow in FIG. .

That is, when a force is applied to the blindfold 60 after the eyes are positioned on the blindfold 60, the corresponding portion of the blindfold 60 of the blindfold 60 is lowered toward the bottom surface of the main body 100 by the pressure The drive switch 17 is turned on, and can be turned off by repeating this operation again.

According to the installation and operation of the drive switch 17, the user easily operates the drive switch 17 while his / her face is in contact with the main body 100 of the light irradiation skin care device.

Therefore, the convenience of operation is improved and the drive switch 17 is operated when the user actually uses the light irradiation skin management device, such as when the face is located in the main body 100 of the light irradiation skin management device, Thereby preventing the light irradiation skin care device from being operated.

In addition, the skin condition sensing unit for measuring the skin condition of the user may be additionally disposed on the forehead and the cheeks of the body corresponding to the large area of the face.

Thus, the skin condition detection unit may be a detection unit that detects one of the user's oily state, water state, and elastic state.

Accordingly, when the skin condition detection unit is additionally provided, the controller 20 can accurately detect the skin condition using the signal state output from the first through third reflection units 11-13 and the skin condition detection unit Thereby grasping the skin condition of the user.

Accordingly, the control unit 20 can control the first through sixth light source array units 31 through 36 in a state more suitable for the skin of the user.

In an alternative example, when the skin condition sensing part is used, the first to third reflection sensing parts 11-13 may be omitted.

The connection unit 200 adjusts the position (i.e., angle) of the main body 100 at an angle most comfortable for the user to use the light irradiation skin management apparatus when the user's face is located in the main body 100 And an angle adjusting unit 210 may be provided. In this case, the downward or upward position of the main body 100 may be changed by the angle adjusting unit 210. Since the angle adjusting unit 210 can be implemented using a hinge or the like, the angle of the main body 100 can be changed by a pressure externally applied by the user's face or the like.

Further, the connection unit 200 may further include a structure capable of changing the length by using an operation switch (not shown) operated by a user. Accordingly, the connection portion 200 is adjusted according to the user's body length (for example, height or sitting height), thereby providing a more convenient posture to the user using the light irradiation skin management device.

The pedestal 300 allows the main body 100 to be stably positioned at the corresponding position.

On the surface of the pedestal 300, a display portion 38, a mode selection portion 16, and a drive switch 17 are located.

Next, with reference to Figs. 4A and 4B, a control method of the light irradiation skin management apparatus having such a structure will be described in detail.

The control unit 20 reads out the signal output from the drive switch 17 and outputs the drive signal to the drive switch 17 It is judged whether or not it is turned on (S11, S12).

Next, when it is determined by the user's operation that the drive switch 17 is in an on state, the control unit 20 sets the first to sixth light source array units 31 to 36 in the initial drive mode, (S13, S14).

In this case, the set time may be, for example, about 30 seconds to 1 minute. Thus, immediately after the drive switch S17 is turned on (i.e., at the time of initial drive), the first to sixth light source array units 31-36 ) Is the intensity of the light that helps the user absorb the light of the skin cells. The light intensities of the first to fifth light source array units 31 to 35 are set such that the pulse width or the duty ratio of the drive signals of the first to fifth light source array units 31 to 35 output from the control unit 20 is Can be changed and controlled.

As described above, the first to sixth light source array units 31 to 36 operate the first to sixth light source array units 31 to 36 in the initial driving mode during the initial driving time, Is more easily penetrated.

As a result, the pores of the user are expanded more quickly at the beginning of use, thereby improving skin care efficiency.

At this time, the driving time of the first to sixth light source array units 31 to 36 is determined using the signal output from the timer 21. [

However, when the drive switch 17 is not in the ON state, the control unit 20 determines the operation state of the drive switch 17 (S12).

The controller 20 controls the first to sixth light source array units 31 to 36 after controlling the states of the lights output from the first to sixth light source array units 31 to 36 in the initial driving mode for the set time, The operation mode of the first to sixth light source array units 31 to 36 is changed to the normal mode state (S15).

Accordingly, the first to sixth light source array units 31 to 36, which are finally determined using the mode selection unit 16 and the first to the first reflection sensing units 11 to 13, The first to sixth light source array units 31 to 36 are operated in the normal mode under the control of the control unit 20 until the operation of the sixth light source array units 31 to 36 is controlled.

After the first to sixth light source array units 31 to 36 are operated in the initial driving mode for a predetermined time, the control unit 20 reads the signal output from the mode selection unit 16 (S16) Determines the skin management mode selected by the user, and outputs the determined skin management mode to the display unit 38 (S17).

At this time, the user or the administrator can select a predetermined number of skin management modes (for example, normal mode, anti-aging mode, wrinkle improvement mode, elasticity enhancement mode, whitening increase mode).

Next, the control unit 20 reads the signals output from the first to third reflection sensors 11-13 (S18), and outputs the signals to the user's skin from the first to third light source array units 31-33 And determines the reflection amount of the light reflected on the skin and outputs the determined reflection amount to the display unit 38 (S19). Therefore, the display unit 38 displays the determined amount of reflection according to the signal output from the control unit 20, in numerical or graphical form.

At this time, the control unit 20 determines the skin condition of the user according to the reflection amount.

The first light source array unit 31 and the second and third light source units 32 and 33 that emit light to the forehead portion respectively emit light to both cheeks And the second and third light source array units 31 for irradiation.

Accordingly, the first reflection sensing part 31 senses the reflection amount reflected by the forehead part, and the second and third reflection sensing parts 31 and 32 sense the reflection amount reflected by the cheek part, respectively.

Accordingly, the control unit 20 determines the skin condition of the forehead portion using the output signal of the first reflectance sensing unit 31, and determines the amount of sunlight by using the output signals of the second and third reflectance sensing units 32 and 33 And the skin condition of the cheek portion, respectively.

Therefore, the positions and the numbers of the first and third reflection sensors 31-33 can be changed according to the portion of the user's skin to be grasped.

The controller 20 controls the display unit 38 to display the skin condition of the user such as a dry state, an intelligent state, a neutral state, a complexity state, etc. of each part (e.g., forehead and both cheeks) A signal can be output, and only the skin condition can be output to the display unit 38 instead of the reflection amount, so that the display unit 38 can display the skin condition instead of the reflection amount.

When the skin management mode selected by the mode selection unit 16 and the skin condition of the corresponding part of the user's face (e.g., forehead and both cheeks) are determined, the controller 20 controls the first To the sixth light source array unit 31-36, and outputs light having an intensity corresponding to the determined skin management mode (S20).

The intensity of the light output from the first to sixth light source array units 31 to 36 (for example, the magnitude of the amplitude of the wavelength of the light) is determined according to the skin condition (S20). The intensity of the light according to the skin condition is also already stored in the memory.

Therefore, the first through third light source array units 31-33, which emit light to the forehead and both cheeks using signals output from the first through third reflectance sensors 31-33, The intensity of light output from the fourth to fourth light source array units 34 to 36 controlling the intensity of light according to the skin condition and irradiating light to the remaining portion is uniformly controlled to a predetermined intensity.

As described above, in the case of this embodiment, when different skin conditions are provided depending on the part of the face, it is individually controlled according to the skin condition of each part, so that the skin care effect is further improved.

The control unit 20 outputs this operation state to the display unit 38 (S20), and allows the user or the administrator to easily grasp the state of the currently output light (i.e., the duty ratio or the amplitude).

After the operation of the first to sixth light source array units 31 to 36 is controlled according to the user's skin condition and the selected skin care mode, the controller 20 controls the skin temperature sensor 14, (S21), and determines the skin temperature of the user who is currently under control and the amount of humidity in the main body 100 of the light irradiation skin management apparatus (S22). At this time, the determined skin temperature and humidity amount can be stored in a memory or the like.

Then, the control unit 20 determines whether the determined skin temperature is higher than the set temperature (S23)

When the determined skin temperature is higher than the set temperature, the control unit 20 determines whether the first to sixth light source array units 31 to 36 are in the current operating state (S24).

Accordingly, when the plurality of light source array units 31 to 36 are in the operating state in a state where the skin temperature is higher than the set temperature, the control unit 20 outputs the drive signals to the plurality of light source array units 31 to 36 Stops the operation of the plurality of light source array units 31-36 (S25). As a result, the user's skin is protected from burns and skin damage due to excessive light output.

Then, the control unit 20 reads the signal output from the drive switch 17 and determines whether the drive switch 17 is in the ON state (S26, S27).

When the drive switch 17 is in the on state, the control unit 20 proceeds to step S16 to select the skin management mode selected by the mode selection unit 16 and the first through third reflection sensing units 11-13 And controls the operations of the first to sixth light source array units 31 to 36 according to the determined skin condition.

However, if it is determined that the state of the drive switch 17 determined in step S27 is in the ON state, it is determined that the skin care operation using the light irradiation skin management apparatus is stopped, and the control unit 20 ends the operation S100).

When the operation of the plurality of light source array units 31 to 36 is in the non-operating state, the control unit 20 proceeds to step S24 to return the skin temperature rises due to the operation of the plurality of light source array units 31 to 36 It is determined that there is no concern and the signal output from the drive switch 17 is read to determine the operation state of the drive switch 17. [

Since the operation states of the plurality of light source array units 31 to 36 are controlled according to the detected skin temperature of the user, the case where the user's skin is adversely affected by the operation of the plurality of light source array units 31 to 36 prevent.

When the determined skin temperature is equal to or lower than the set temperature in step S23, the control unit 20 compares the determined humidity with the set humidity (S28).

If the determined amount of humidity is greater than the set humidity, the control unit 20 determines the signal state output to the ventilation fan 37 and determines whether the ventilation fan 37 is currently operating (S29).

Accordingly, when the ventilation fan 37 is in operation, the amount of moisture in the main body 100 is reduced due to the operation of the ventilation fan 37. Therefore, the control unit 20 proceeds to step S26, It is determined whether the operation state of the switch 17 has been changed (S26, S27).

However, when the ventilation fan 37 is not operated in step S29, the control unit 20 determines that the ventilation fan 37 is not operating even when the humidity level in the main body 100 is equal to or higher than the set humidity And outputs a driving signal to the ventilation fan 37 to operate the ventilation fan 37. [

In this way, when the humidity in the main body 100 is higher than the set humidity, the ventilation fan 37 is driven to reduce the humidity in the main body 100, thereby preventing the user from breathing trouble or discomfort due to excessive humidity. do.

If the humidity level is equal to or lower than the set humidity level, the humidity state in the main body 100 is not in a state requiring additional control, so that the control unit 20 uses the signal state applied to the ventilation fan 37 It is determined whether the ventilation fan 37 is currently operating (S31).

The control unit 20 controls the signal to be applied to the ventilation fan 37 so that the ventilation fan 38 is turned on and the ventilation fan 38 is activated, ). Then, the process proceeds to step S26 to determine whether the drive switch 17 is in an ON state.

However, if it is determined in step S31 that the ventilation fan 37 is in the non-operating state, the control unit 20 immediately goes to step S26 to determine whether the drive switch 17 is in the ON state.

The operation of the first to sixth light source array units 31 to 36 is firstly investigated in a pulse type during the set time when the drive switch 17 is operated to depart from the adjustment of only the irradiation time and output of the single light source at a time, To make it more suitable for accepting light energy. Then, the operation of the first to sixth light source array units 31 to 36 is controlled using the mode or the reflection amount selected by the user. As a result, it is possible to minimize the damage to the skin while at the same time allowing the maximum skin improvement effect to be seen.

The total driving time for managing the user's face using the light irradiated skin managing apparatus according to this example may be about 5 minutes to 10 minutes. This driving time may be determined by the user using the hand- Is much shorter than when it is investigated.

Therefore, since the time for receiving the skin care is reduced, the fatigue of the user is reduced and the boredom is reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
