The present invention relates to a portable skin light therapy device, and more particularly, to a portable skin light therapy device having a structure in which therapeutic light is irradiated only when it comes into contact with the skin.

Acne, which is one of the representative skin diseases, appears mainly in men and women before and after puberty, and hormones that begin to be released during puberty stimulate sebaceous glands to enlarge sebaceous glands and promote sebum secretion. This acne is an inflammatory disease of the hair sebaceous glands, and the occlusion of hair follicles causes the formation of a scrim (i.e., black or white cotton) consisting of sebum, keratin and microorganisms.

In particular, the increased inflammation of the sebaceous glands attached to the hair follicles can cause serious skin damage, which is difficult to cure and more likely to develop into more serious conditions.

In addition, the skin treatment unit 120 is connected to the main body 110, the skin treatment unit 120 includes a housing 122, the light source 124 and the skin contact portion 125.

As shown in FIG. 2, the housing 122 is formed with an inner groove having a predetermined thickness to form an inner groove formed in a recess below the reference plane and a thickness thereof, when the surface in contact with the skin is viewed as a reference plane. . At this time, the shape of the opening may be circular as shown, but is not limited thereto.

The light source unit 124 is installed in the inner groove of the opening, and includes a plurality of light emitting devices 124a such as a light emission diode (LED) or a laser diode (LD). Since the light emitted from the light source unit 124 includes a blue light of the 410 nm wavelength band that treats infectious acne with an antiviral effect, and a red light of the 635 nm wavelength band having a cell regeneration effect, rapid wound recovery, and pain reduction effect, Depending on the purpose, namely whether acne treatment or skin care may be used to select the appropriate light, in some cases may be implemented so that the two light beams are irradiated at the same time.

Skin contact portion 125 is a portion of the portable skin light treatment device 100 to be in contact with the skin to be treated is formed on the upper end of the outer structure of the opening, the electricity supply module for supplying power to the light source unit 124 through contact with the skin It contains one or more (125b). That is, the power supply module 125b may be one, or two or more.

In particular, when some of the power supply modules 125b do not detect contact when there are two or more power supply modules 125b, the control unit sends an alarm signal to generate only an alarm sound or to stop irradiation of the light source at the same time as the alarm sound. Can be controlled.

For example, when there are four power supply modules 125b, the controller controls an operation of the light source unit 124. When two are not contacted, an alarm sounds and two are not contacted. Even when driven, the light emitting device 124a is turned off to block light irradiation, and when three are contacted, the light source unit 124 is driven and the light emitting device 124a is turned on to irradiate light to further improve the safety of the portable skin light treatment device. Can be.

With reference to Figures 3 and 4 will be described in more detail with respect to the power supply module (125b).

First, as shown in FIG. 3, in which an embodiment of the electricity supply module 125b included in the skin contact part 125 is illustrated, one embodiment of the electricity supply module 125b is a pair of contact parts that are surrounded by an insulator, that is, the first contact part. It may have a structure including a 102a and a second contact portion (102b). In this case, since the first contact portion 102a is connected to the ground portion 103 and the second contact portion 102b is connected to the light source portion 124 or to a control portion for controlling the driving of the light source portion 124, The light source unit 124 may be driven by energizing only when the contact portion is in contact with the skin at the same time. Therefore, it is preferable that the skin contact part 125 is made of an insulator 125a in all of the remaining areas except for the energization module 125b, that is, the pair of contact parts. As shown in FIG. 3, the pair of contact portions included in the energization module 125b may be, for example, a pin shape of a conductive material, but may be formed in the same manner as compared with the reference surface of the skin contact portion 125, but protrude more than the reference surface. And may be desirable for energizing both contact portions.

In addition, as shown in FIG. 4, which shows another embodiment of the energization module 125b included in the skin contact part 125, the energization module 125b is formed by being surrounded by an insulator 125a and its insulator. It may have a structure including a second contact portion 102b formed in the outer region.

Here, the first contact portion 102a is a predetermined region made of a conductive material, but is shown in a quadrangular shape in FIG. 4, but the shape is not limited. The insulator 125a surrounding the first contact portion 102a is preferably formed in a band shape having a predetermined width surrounding the first contact portion 102a. The second contact portion 102b may be formed of a conductor material in an outer region of the insulator, and may be formed in a band shape having a predetermined width surrounding the insulator 125a or as shown in FIG. 4. All of the remaining regions except for the insulator 125a surrounding the 102a may be made of a conductor.

In this case, since the first contact part 102a is connected to the ground part 103 and the second contact part 102b is connected to the light source part 124, the first contact part 102a is energized only when a pair of contact parts are in contact with the skin at the same time. 124 may be driven.

On the other hand, the plurality of light emitting elements 124a constituting the light source unit 124 and the at least one conduction module 125b may be implemented to match one another 1: one conduction module 125b to the plurality of light emitting elements 124a. May be implemented to match.

Referring to FIG. 5, which is a schematic rear view of a portable skin light therapy apparatus according to an embodiment of the present disclosure, the main body 120 may further include a control box 115. In some cases, an alarm sound is generated to generate an alarm sound. Light mode selection means (not shown) for selecting the means (not shown) and the type of light rays (red, blue, both, etc.) to be irradiated may be further included.

First, the control box 115 includes an operation unit including a time selection button 116 and a setting button 117 for selecting the duration of light emission of the light source unit 124. The time selection button 116 increases the time value. It may consist of a button for reducing and a button for decreasing. Here, the 'light emission duration' is a total cumulative time for continuously emitting light from the light source unit 124, that is, the light emitting element 124a when the energization module 125b is in contact with the skin 200, to protect the skin 200. For this reason, when a predetermined light emission duration is exceeded by setting a predetermined time, it means a time taken for the light emission by the light source unit 124 to be automatically stopped even if the power supply module 125b is in contact with the skin.

This light emission duration is when the part or the whole of the electricity supply module 125b is not in contact with the skin 200, the flow of time is stopped and at the same time the light emission of the light source unit 124 is stopped, for a certain time (for example 1 minute If the contact occurs again within), the flow of time is resumed at the same time as the light emission, otherwise it may be controlled to switch to the initial state.

In addition, the control box 115 may further include one or more of the display window 118 and the lamp 119. The display window 118 may be an operating state, a setting state, a remaining battery level, or the like of the portable skin phototherapy device 100. It performs a function of displaying a variety of information such as the remaining time of the light emission duration, the lamp 119 indicates the power ON and the charging state.

Looking at the operation sequence of the portable skin light therapy device 100 according to an embodiment of the present invention configured as described above are as follows.

First, when the power switch 114 of the portable skin light therapy device 100 is turned on, the control unit turns on the power ON indicator lamp among the lamps 119 of the control box 115 and automatically selects the value as the 'default emission duration' and waits for the operation. To be controlled. In this case, the user may select a desired light emission duration using the time selection button 116 for selecting the light emission duration, and may select a desired treatment light using the light beam mode selection means.

The basic light emission duration and the treatment light may be the treatment light set at a predetermined time and initialization stored inside the portable skin light treatment device 100, and in some cases, may be the time and treatment light set at the previous skin treatment. have. At this time, if the basic light emission duration and the treatment light is a predetermined time and the treatment light pre-stored in the interior of the treatment device, even if the light emission duration and the treatment light mode is changed as necessary, the light emission duration to the pre-stored time when the skin treatment is finished And therapeutic rays are initialized. In addition, when the basic luminescence duration and the treatment beam are the time and treatment beam set in the previous skin treatment, the luminescence duration and the treatment beam are respectively maintained until further modification is made.

After the light emission duration setting is completed, when the skin treatment unit 120 contacts the skin 200, power is supplied to the light source unit 124 by contacting the energization module 125b and the skin, and the controller controls the light source unit 124. The light emitting device 125 emits light to control the portable skin light therapy apparatus 100 to start the treatment of the skin 200. In addition, the countdown of the luminescence duration begins when treatment begins.

When the power supply module 125b is not in contact with the skin 200, light is not supplied to the light source unit 124, so that light emission from the light source unit 124 is stopped. In this case, the control unit stops the countdown of the light emission duration. When power is supplied to the light source unit 124 within a predetermined time (for example, 1 minute) after the light emission of the light source unit 124 is stopped, the light source unit 124 emits light again, and at the same time the countdown stopped at the same time is stopped. You can control the restart.

In addition, when a predetermined time is exceeded or the setting button 117 of the control box 115 is pressed after the light emission is stopped, it may be controlled to be selected as the 'default light emission duration' value and to be in the operation standby state. When the standby state lasts for a predetermined time, it is preferable that the power of the portable skin light therapy device 100 is automatically changed to the off state.

The present invention has been shown and described with reference to the preferred embodiments as described above, but is not limited to the above embodiments and those skilled in the art without departing from the spirit of the present invention.
