Summary of the Invention

Problems to be Solved by the Invention

[0005] In a skin treatment device, i.e., a beauty device, having an irradiation unit provided with a plurality of light sources composed of light-emitting diodes (LEDs), in order to enhance the skin treatment effect, i.e., the beauty effect, it is necessary to irradiate light at a predetermined irradiation level, i.e., irradiation amount, toward the skin to be treated such as the face. However, in a conventional skin treatment device, since light at a constant irradiation level is irradiated from the light-emitting diodes, in order to enhance the treatment effect, it is necessary to keep a predetermined distance between the skin to be treated and the irradiation unit, and further, it is necessary to oppose the skin to be treated to the irradiation unit so that the whole of the skin to be treated does not deviate from the irradiation unit.

[0006] As described in Patent Document 2, in a skin treatment device having a layered member, i.e., a sheet-like member, provided with a plurality of light-emitting diodes as the irradiation unit, since the irradiation unit is attached to the body, the distance between the skin to be treated and the irradiation unit can be kept constant, and the irradiation unit can be opposed to the skin to be treated. However, this type of skin treatment device cannot attach the irradiation unit to a plurality of sites according to the location of the skin to be treated.

[0007] When performing treatment by opposing a skin treatment device or a beauty device that irradiates light at a constant irradiation level from each light-emitting diode to a plurality of skins to be treated, there is a problem that an optimal treatment effect cannot be obtained according to the arrangement situation of the device with respect to the skin to be treated, such as the distance between the skin to be treated and the irradiation unit and the opposing position.

[0008] An object of the present invention is to provide a beauty device capable of enhancing the skin treatment effect according to the condition of the skin to be treated.

Means for Solving the Problems

[0009] The beauty device of the present invention includes an irradiation panel on which a plurality of light-emitting diodes for irradiating light onto the skin to be treated on the body are dispersedly arranged, a distance sensor provided on the irradiation panel for measuring the distance between the skin to be treated and the irradiation panel, and a control unit that calculates the distance between the irradiation panel and the skin to be treated according to the level of reflected light from the skin to be treated detected by the distance sensor and adjusts the irradiation intensity of the light-emitting diodes based on the calculation result.

[0010] The beauty device of the present invention includes an irradiation panel on which a plurality of light-emitting diodes for irradiating light onto the skin to be treated on the body are dispersedly arranged, a temperature sensor provided on the irradiation panel for measuring the temperature of the skin to be treated, and a control unit that calculates the temperature of the skin to be treated according to the detection signal from the skin to be treated detected by the temperature sensor and adjusts the irradiation intensity of the light-emitting diodes based on the calculation result.

Advantages of the Invention

[0011] When a distance sensor is provided on the irradiation panel, the irradiation level of the light-emitting diodes provided on the irradiation panel can be adjusted according to the distance between the irradiation panel and the skin to be treated. Therefore, even if the distance changes, the skin to be treated can be irradiated with light at an optimal irradiation level from the start to the end of irradiation, enhancing the skin treatment effect.

[0012] When a temperature sensor is provided on the irradiation panel, the irradiation level of the light-emitting diodes provided on the irradiation panel can be adjusted according to the temperature of the skin to be treated. Therefore, the skin to be treated can be irradiated with light at an optimal irradiation level, enhancing the skin treatment effect.

Mode for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The beauty device 10 shown in FIGS. 1 and 2 has a substantially rectangular device body 11, and the device body 11 includes a case member 12 and an irradiation panel 13 provided on the front surface side thereof. When this beauty device 10, that is, the skin treatment device, is used to enhance the beauty effect of the face as shown in FIG. 2, the irradiation panel 13 is arranged to face the face of the body so that the long side of the irradiation panel 13 is along the vertical direction of the face. In order to use the beauty device 10 by placing it on a table or the like or on a wall surface, a stand or the like is attached to the device body 11.

[0015] The long side of the irradiation panel 13 in the vertical direction is 295 mm, and the short side in the horizontal direction is 195 mm. A plurality of recesses 14 are formed in the irradiation panel 13, and a total of 56 recesses 14 are arranged in a matrix in a checkerboard pattern with 8 rows in the horizontal direction and 7 columns in the vertical direction. In each recess 14, either the first light-emitting diode unit (LED unit) 21 or the second light-emitting diode unit (LED unit) 22 is arranged. However, the size of the irradiation panel 13 is not limited to the above-described dimensions and may be a small size that can fit in the palm of the user's hand. Also, the number of each of the LED units 21 and 22 is not limited to the above-described number, and any number can be arranged in plural, and as long as the LED units 21 and 22 are arranged dispersedly on the irradiation panel 13, it is not limited to the matrix arrangement. In this specification, light-emitting diodes and LEDs synonymous with them are described in a mixed manner.

[0016] The first light-emitting diode unit 21 is an infrared LED unit. As shown in Fig. 3(A), it has one infrared light-emitting diode IR that irradiates infrared rays, two red light-emitting diodes R that emit red light, and two yellow light-emitting diodes Y that emit yellow light. The infrared light-emitting diode IR is arranged at the center of the first LED unit 21, and with the infrared light-emitting diode IR as the center, the red light-emitting diodes R and the yellow light-emitting diodes Y are alternately arranged in the circumferential direction at the same radial distance from it.

[0017] The second light-emitting diode unit 22 is a blue LED unit. As shown in Fig. 3(B), it has one blue light-emitting diode B that emits blue light, two red light-emitting diodes R that emit red light, and two yellow light-emitting diodes Y that emit yellow light. The blue light-emitting diode B is arranged at the center of the second LED unit 22, and with the blue light-emitting diode B as the center, the red light-emitting diodes R and the yellow light-emitting diodes Y are alternately arranged in the circumferential direction at the same radial distance from it.

[0018] Thus, in the first LED unit 21, an infrared light-emitting diode IR is arranged at the center, and red light-emitting diodes R and yellow light-emitting diodes Y are arranged around it. On the other hand, in the second LED unit 22, a blue light-emitting diode B is arranged at the center, and red light-emitting diodes R and yellow light-emitting diodes Y are arranged around it. As shown in FIGS. 1 and 2, both the first and second LED units 21 and 22 are alternately arranged in the row direction, that is, the horizontal direction, and are also alternately arranged in the vertical direction, that is, the column direction, on the irradiation panel 13, and are arranged in a matrix in a checkerboard pattern as a whole.

[0019] Each light-emitting diode in the LED units 21 and 22 comprises a semiconductor chip which is a diode, a reflector, and a lens to form a lamp, and is also called a light-emitting diode lamp.

[0020] The beauty effect, that is, the skin treatment effect, on the skin when the skin is irradiated with light from each light-emitting diode, that is, the light-emitting diode lamp, is as follows.

[0021] When the skin such as a person's face is irradiated with red light, the light reaches deep into the dermis to activate fibroblasts, has an effect of promoting collagen production, and is effective in improving dry skin and wrinkles.

[0022] When the skin is irradiated with yellow light, it is effective in treating skin that has aged due to general ultraviolet rays, and has effects such as reducing pigmentation, erythema, and wrinkles.

[0023] When the skin is irradiated with blue light, it has an effect of improving and treating inflammatory and non-inflammatory acne, and has an effect of suppressing the darkening of melanocytes by combined irradiation with red light.

[0024] Furthermore, when the skin is irradiated with infrared rays, it reaches deep into the skin and muscles, dilates blood vessels, has an effect of improving blood flow, a muscle relaxation effect, and an effect of improving metabolism, stimulates fibroblasts in the dermis layer, and has a collagen production effect and an effect of improving skin moisturization and elasticity.

[0025] The red light-emitting diode R emits light with a wavelength of 625 nm, but it is not limited to 625 nm as long as it is within the wavelength range of red light from 625 to 780 nm. The yellow light-emitting diode Y emits light with a wavelength of 590 nm, but it is not limited to 590 nm as long as it is within the wavelength range of yellow light from 565 to 590 nm. The blue light-emitting diode B emits light with a wavelength of 470 nm, but it is not limited to 470 nm as long as it is within the wavelength range from 450 to 485 nm. Similarly, the infrared light-emitting diode IR emits near-infrared light with a wavelength of 940 nm, but it is not limited to 940 nm as long as it is within the infrared range from 700 nm to 1 mm.

[0026] The lower end of the irradiation panel 13 serves as the operation display unit 15, and five treatment selection switches 23 to 27 are provided.

[0027] The selection switch 23 is a derma roller switch. The skin texture refers to the unevenness of the skin surface. Skin with fine texture appears transparent and beautiful. The main causes of reduced skin texture and firmness are aging and ultraviolet radiation. When this selection switch 23 is operated, the yellow light-emitting diode Y irradiates the skin with yellow light with a wavelength of 590 nm, which is effective for treating aging skin, at maximum output. Furthermore, by irradiating the skin with red light with a wavelength of 625 nm from the red light-emitting diode R, which has the effect of promoting the production of collagen in the dermis layer and reducing MMP-1 (an enzyme that destroys collagen), the production of collagen can be promoted. In addition, the skin is also irradiated with near-infrared light from the infrared light-emitting diode IR, which has the effect of promoting metabolism.

[0028] The selection switch 24 is an adolescent skin switch. Acne, which is common during adolescence, is a skin problem mainly caused by acne bacteria existing on the skin surface causing inflammation in pores and other areas. Acne bacteria cause inflammation while generating porphyrin. When this selection switch 24 is operated, blue light with a wavelength of 470 nm is irradiated onto the skin from the blue light-emitting diode B. Thereby, reactive oxygen species are generated by reacting with porphyrin to sterilize acne bacteria, and acne-prone skin and redness related to acne can be improved. At the same time, by irradiating red light with a wavelength of 625 nm with a high penetration rate, collagen production can be promoted, and a rapid skin repair effect can be obtained.

[0029] The selection switch 25 is a rough / dry skin switch. Skin roughness is closely related to skin dryness. When this selection switch 25 is operated, near-infrared light is irradiated from the infrared light-emitting diode IR at maximum output. Thereby, the metabolism of the skin can be promoted. When near-infrared light and red light with a wavelength of 625 nm with a high penetration rate of the skin are irradiated at the same time, collagen production can be promoted, and a rapid repair effect on rough skin can be obtained.

[0030] The selection switch 26 is a glowing skin switch. The causes of dullness and spots on the skin are due to the unevenness of the skin surface due to aging being seen as light and dark (fine shadows), or parts with poor blood circulation appearing blackened, or the darkening of melanocytes due to ultraviolet rays. Therefore, when the selection switch 26 is operated, yellow light with a wavelength of 590 nm, which is effective for treating skin aged by ultraviolet rays, is irradiated onto the skin at maximum output, and further, blue light with a wavelength of 470 nm and red light with a wavelength of 625 nm are irradiated at medium level, that is, medium intensity, so that the darkening of melanocytes can be suppressed.

[0031] The selection switch 27 is a scalp care switch. Hair loss and gray hair are caused in part by a decrease in blood circulation and metabolism of capillaries due to stress and aging. Therefore, when this selection switch 27 is operated, near-infrared light of 940 nm is irradiated at maximum output and red light of 625 nm is irradiated at maximum output to improve the scalp environment, thereby stimulating hair matrix cells, activating dermal papilla cells, and promoting hair growth. In addition, weak blue light is irradiated onto the scalp for the purpose of sterilizing the scalp.

[0032] In this way, when any one of the treatment selection switches 23 to 27 is operated, any one of the light-emitting diodes is irradiated and the irradiation intensity is set according to the selected treatment mode.

[0033] Below the treatment selection switch, a timer operation switch 28 and a timer display unit 29 are provided. The time set by operating the timer operation switch 28 is lit and displayed on the timer display unit 29. For example, with a minimum time of 5 minutes and a maximum time of 30 minutes, the treatment time can be set in 5-minute units each time the timer operation switch 28 is operated once. Reference numeral 30 is a start / stop switch for treatment. It is operated when executing the treatment program selected by the treatment selection switches 23 to 27, and when operated during execution, the treatment is stopped.

[0034] As shown in FIG. 1, the timer operation switch 28 and the start / stop switch 30 each have a pattern indicating their switch functions shown within a frame line. The treatment selection switches 23 to 27 are shown only by the frame line, and although the pattern is omitted, a pattern indicating the switch function is marked.

[0035] As shown in FIG. 1, two distance sensors 31 and 32 are provided at the vertical center of the irradiation panel 13 with a distance therebetween left and right. Each of the distance sensors 31 and 32 is a photodiode that operates as a light detector, has a window for receiving the reflected light of the light irradiated on the skin to be treated such as a face, and can measure the distance between the skin to be treated and the distance sensors 31 and 32 based on the level of the reflected light. The distance between the skin to be treated and the distance sensor 31 is substantially equal to the distance between the skin to be treated and the irradiation panel 13. As each of the distance sensors 31 and 32, a phototransistor may be used. As the phototransistor, for example, a type in which a bipolar transistor is enclosed in a case and light reaches the pn junction of its base-collector can be used.

[0036] By detecting the distance between the irradiation panel 13 and the skin to be treated by the distance sensors 31 and 32, the irradiation intensity of infrared rays and red, that is, the irradiation level can be automatically adjusted. That is, when the distance is farther than the set distance, the irradiation intensity can be increased, and when it is closer, the irradiation intensity can be decreased, so that an optimal irradiation amount can be irradiated on the skin to be treated. However, the irradiation levels of all the light emitting diodes may be adjusted according to the distance.

[0037] To measure the distance between the irradiation panel 13 and the skin to be treated, one distance sensor may be provided. As shown in FIGS. 1 and 2, when two distance sensors 31 and 32 are provided with a distance therebetween left and right, for example, when the face is the skin to be treated, the left-right balance can be detected according to the reflected light levels received by the two distance sensors 31 and 32, and it is possible to determine whether or not the face is facing the central portion of the irradiation panel 13 as described later. When it is detected that the face is facing the central portion of the irradiation panel 13, the temperature of the face as the skin to be treated can be detected.

[0038] Between the two distance sensors 31 and 32, a temperature sensor 33 for measuring the temperature of the skin to be treated is arranged. As the temperature sensor 33, a thermopile type infrared sensor is used. The higher the temperature of a person's skin, the stronger the infrared rays emitted, and the infrared sensor can measure the skin temperature by detecting the infrared rays from the skin. The temperature sensor 33 is not limited to an infrared sensor, that is, a radiation temperature sensor, and other types of sensors can be used as long as they are non-contact temperature sensors. The timing of temperature detection can be determined by the reflection levels and balance of the two distance sensors 31 and 32 as described later.

[0039] FIG. 4 is an enlarged cross-sectional view showing the internal structure of the temperature sensor 33. On a printed circuit board 34 incorporated inside a case member 12, a temperature sensor 33 composed of an infrared sensor is attached by a spacer 35, and a high-density polyethylene lens 36 having a Fresnel lens configuration is attached to an irradiation panel 13. In FIGS. 1 and 2, the portion of the lens 36 is shown as the temperature sensor 33.

[0040] On a display portion provided at the lower end of the irradiation panel 13, three irradiation mode switches, namely, a temperature measurement mode switch 41, a distance measurement mode switch 42, and a goggle mode switch 43, are provided. The temperature measurement mode switch 41 is a switch for setting whether to operate the temperature sensor 33. When the temperature measurement mode switch 41 is turned on, the skin temperature is detected and the light emission output of the light-emitting diode is adjusted. Further, when the temperature measurement mode switch 41 is turned on, the skin temperature measured during skin treatment by the temperature sensor 33 is compared with the history of detection values for a predetermined number of times obtained by the temperature sensor 33, for example, the average skin temperature of the detection values from about the past 10 to 100 times, or the skin temperature transition is compared, and thereby the irradiation amount is automatically adjusted. The detection values of the skin temperature for a predetermined number of times are stored in a memory. For example, when a skin temperature exceeding a certain threshold value is detected compared with the value of the average skin temperature, the irradiation amount is decreased, and when it is lower than the threshold value, the irradiation amount is increased for control.

[0041] The distance measurement mode switch 42 detects the distance between the skin to be treated and the irradiation panel 13, and is a switch for setting whether to automatically adjust the irradiation amount according to the distance or to irradiate the skin to be treated with a fixed amount of irradiation without measuring the distance. The user can select whether to adjust the irradiation amount according to the distance or to irradiate with a fixed amount of irradiation. Also, when both the temperature measurement mode switch 41 and the distance measurement mode switch 42 are turned on, the irradiation level, that is, the irradiation intensity, is adjusted according to both the skin temperature and the distance.

[0042] The goggle mode switch 43 is a switch for selecting whether to irradiate the face with the goggles on or without the goggles on. When the goggle mode switch 43 is operated to irradiate the face with light without wearing the goggles, the irradiation amount is automatically adjusted so that the irradiation level is lower than when wearing the goggles.

[0043] A power switch 44 is provided below the three mode switches. When this power switch 44 is turned on, all other switches can be operated. When the power is turned off, all the displays are turned off, and when it is turned off during the treatment, the irradiation is forcibly stopped. As the power switch, a logo mark or a trademark may be displayed within the range indicated by the frame so that the logo mark or the trademark also serves as the power switch.

[0044] FIG. 5 is a block diagram showing the control circuit of the beauty device 10. The detection signals of the distance sensors 31 and 32 and the temperature sensor 33 described above are sent to the control unit 45. Further, operation signals of the treatment selection switches 23 to 27 and the timer operation switch 28, and operation signals of the temperature measurement mode switch 41, the distance measurement mode switch 42, and the goggle mode switch 43 are sent to the control unit 45. The control unit 45 includes a memory storing a control program, data, etc., and a microprocessor (MPU) that calculates control signals. The light emission levels, that is, the light emission outputs of the light emitting diodes constituting the respective LED units 21 and 22 are controlled by the control signals from the control unit 45, and the operation display unit 15 and the timer display unit 29 are controlled to light up. As shown in FIG. 2, the DC jack 46 is provided on the side surface of the device main body 11, and the beauty device 10 is driven and controlled by the power supplied from the outside to the control circuit. The detection history of the skin temperature for a predetermined number of times is stored in the memory of the control unit 45.

[0045] FIG. 6 is a control diagram showing the output signal of the distance sensor and the timing of the light emission pulses to the light emitting diodes in the respective LED units. When the user operates the distance measurement mode switch 42 to select a mode in which the irradiation amount of each light emitting diode is automatically adjusted according to the distance between the skin to be treated and the irradiation panel 13, the detection signals of the distance sensors 31 and 32 are read by the control unit 45. When the detection signal is read by the control unit 45, the light emitting diodes are lit in synchronization with the reading timing P. The light emitting diodes to be lit and the irradiation intensity are set according to the treatment program set by the treatment selection switches 23 to 27.

[0046] When the mode for automatically adjusting the irradiation dose is selected, in the control unit 45, the distance between the irradiation panel 13 and the skin to be treated is calculated according to the reflection level of the reflected light from the skin to be treated received by the distance sensor, and the light emission output of the light-emitting diode is adjusted based on the calculation result. For example, when it is standard use to use in the range where the distance L between the irradiation panel 13 and the skin to be treated is 100 to 250 mm, the distance obtained by adding a certain allowable value to the intermediate value of this range is defined as the appropriate distance, and the irradiation dose of the light-emitting diode at that time is set to the reference value. When the distance L is closer than the appropriate distance, the level of the detection signal of the distance sensor becomes high, and accordingly, the irradiation dose of the light-emitting diode is set low. On the other hand, when the distance L is farther than the appropriate distance, the level of the detection signal of the distance sensor becomes low, and accordingly, the irradiation dose of the light-emitting diode is set high. Thereby, the irradiation intensity of the light-emitting diode irradiated on the skin such as the face during the treatment can be kept within a certain range. When the irradiation time set by the user operating the timer operation switch 28 elapses, the light-emitting diode is turned off.

[0047] Since two distance sensors 31 and 32 are provided, the detection of the distance L may be the intermediate value of the two distance sensors 31 and 32, or may be the value of either one. Also, the beauty device 10 may be configured with only one distance sensor.

[0048] The light emission output of each light-emitting diode is pulse light emission, and the light emission output intensity is adjusted by PWM (pulse width modulation) control or PFM (pulse frequency modulation) control. PFM control is a method of controlling the output voltage value to the light-emitting diode by changing the switching frequency while fixing the on-time or off-time to change the duty ratio. In contrast, PWM control is a method of controlling by fixing the on-time and increasing the frequency when increasing the duty ratio and decreasing the frequency when decreasing the duty ratio.

[0049] FIG. 7(A) to FIG. 7(F) are control diagrams showing control patterns in the case where the timing for detecting the skin temperature with the face as the skin to be processed is set by the output signals of two distance sensors 31 and 32. The left and right of the two distance sensors 31 and 32 are based on the position of the irradiation panel 13 shown in FIG. 1. The first distance sensor 31 is arranged on the left side of FIG. 1, and the second distance sensor 32 is arranged on the right side.

[0050] FIG. 7(A) shows the case where the distance between the irradiation panel 13 and the face is too close. In this case, the reflection level signals received by the two distance sensors 31 and 32 exceed the temperature reading threshold S. FIG. 7(B) shows the case where the face is too close to the right side of the irradiation panel 13. In this case, the reflection level signal of the left distance sensor 31 is within the range of the temperature reading threshold S, while the right distance sensor 32 exceeds the threshold S. Conversely, FIG. 7(C) shows the case where the face is too close to the left side of the irradiation panel 13. In this case, the reflection level signal of the right distance sensor 32 is within the range of the temperature reading threshold S, while the left distance sensor 31 exceeds the threshold S.

[0051] On the other hand, FIG. 7(D) shows the case where the face is slightly far to the right with respect to the irradiation panel 13. In this case, the reflection level signal of the right distance sensor 32 is within the range of the temperature reading threshold S, while the left distance sensor 31 is below the threshold S. Conversely, FIG. 7(E) shows the case where the face is slightly far to the left with respect to the irradiation panel 13. In this case, the reflection level signal of the left distance sensor 31 is within the range of the temperature reading threshold S, while the right distance sensor 32 is below the threshold S.

[0052] Figure 7(F) shows a case where the position and distance with respect to the irradiation panel of the face are appropriate. Both reflection signal levels are within the range of the threshold value S, and the skin temperature of the face is measured. When performing a treatment by directing the irradiation panel 13 toward the skin to be treated, it is not easy to always keep a constant distance and a constant position in the left - right direction with the skin to be treated facing the irradiation panel 13. However, by providing a plurality of distance sensors, it is possible to always irradiate the skin to be treated, such as the face, under constant conditions.

[0053] FIG. 8 is a front view showing a modified example of the operation display unit 15 provided at the lower end of the irradiation panel 13. FIG. 8(A) shows a state where the power switch 44 is turned on, and FIG. 8(B) shows a state where the power switch 44 is turned off. When the power switch 44 is turned on, the treatment selection switches 23 - 27, the temperature measurement mode switch 41, the distance measurement mode switch 42, the goggle mode switch 43, etc. shown in FIG. 1 are lit and displayed. On the other hand, when the power switch 44 is turned off and the beauty device 10 is not in use, as shown in FIG. 8(B), the display is turned off except for the part of the power switch 44.

[0054] The operation display unit 15 shown in FIG. 8 is provided at the lower end of the irradiation panel 13 in the same manner as that shown in FIG. 1. However, by providing a separate operation panel from the irradiation panel 13, only the LED units 21 and 22 may be provided on the irradiation panel 13, and the operation display unit 15 may be provided on the operation panel.

[0055] The present invention is not limited to the above - described embodiments, and various modifications can be made without departing from the gist thereof.
