Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when light and warm air are simultaneously applied to the scalp, the scalp becomes too hot. Therefore, in order to prevent the scalp from becoming too hot, if the intensity of the light emitted by the LED is weakened, the intensity of the light irradiated on the scalp is weakened, and a sufficient hair growth effect cannot be expected. Therefore, in view of the above circumstances, the present disclosure aims to provide a light beauty device that can irradiate light with sufficient intensity while preventing the skin surface from becoming too hot.

Means for Solving the Problems

[0005] According to one aspect of the present invention, a light beauty device is provided. The light beauty device includes a light emitting means, a cooling means, and a control means. The light emitting means irradiates light onto the skin surface. The cooling means cools by supplying an air flow to the skin surface. The control means operates the cooling means so as to cool the skin surface irradiated with light by the air flow.

[0006] According to such an aspect, it is possible to irradiate light with sufficient intensity while preventing the skin surface from becoming too hot.

Embodiments for Carrying Out the Invention

[0008] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Various characteristic matters shown in the following embodiments can be combined with each other.

[0009] In addition, in this specification, the “section” may include, for example, hardware resources implemented by a circuit in a broad sense and information processing of software that can be specifically realized by these hardware resources. Also, in this embodiment, various information is handled, and these information can be communicated and calculated on a circuit in a broad sense regardless of whether they are represented by the high and low of signal values as a set of binary bits composed of 0 or 1, represented by physical numerical values of signal values, or represented by quantum superposition.

[0010] In addition, a circuit in a broad sense is a circuit realized by appropriately combining at least a circuit, circuitry, a processor, a memory, etc. That is, it includes an application specific integrated circuit (ASIC), a programmable logic device (for example, a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)), etc.

[0011] <Optical beauty device 1> First, the overall configuration of the optical beauty device 1 of the present disclosure will be described. FIG. 1 is a front perspective view of the optical beauty device. FIG. 2 is a rear perspective view of the optical beauty device. FIG. 3 is a perspective view showing a state where the light emitting means is removed from the hair dryer. FIG. 4 is a perspective view of the light emitting means viewed obliquely from below. FIG. 5 is an exploded perspective view of the light emitting means. FIG. 6 is a diagram (a) showing the internal configuration of the hair dryer and a diagram (b) showing the appearance of the hair dryer viewed from the same angle as (a). In the following description, the upper side in FIG. 1 will also be referred to as "upper", the lower side as "lower", the front left side as "front" and "front surface", and the rear right side as "rear" and "back surface".

[0012] The optical beauty device 1 shown in FIG. 1 etc. is used on the skin surface of a user. This optical beauty device 1 has a light emitting device (light emitting means) 2 and a hair dryer (cooling means) 3, and the light emitting device 2 and the hair dryer 3 are configured to be detachable from each other. The hair dryer (cooling means) 3 is provided with an air outlet 312a through which an air flow passes and is supplied to the skin surface, and the light emitting device 2 is provided above (laterally) and in the vicinity (proximate or adjacent) of the air outlet 312a. In the present disclosure, the optical beauty device 1 can be realized with such a simple configuration. Further, since the optical beauty device 1 is composed of the hair dryer 3 and the light emitting device 2 that is detachable from the hair dryer 3, after using the hair dryer 3, it can be used as the optical beauty device 1 by a simple operation of attaching the light emitting device 2. That is, it is easy to get used to using the optical beauty device 1.

[0013] The light emitting device (light emitting means) 2 is configured to irradiate light onto the skin surface. Here, the skin surface refers to the surface of the human body including the scalp, facial skin, body skin, and hair of a human. By appropriately setting the wavelength of the light irradiated by the light emitting device 2, the optical beauty device 1 can exhibit a desired beauty effect. On the other hand, the hair dryer (cooling means) 3 is configured to cool the skin surface by supplying an air flow.

[0014] When light is irradiated from the light emitting device 2, the temperature of the skin surface rises. However, if the temperature of the skin surface rises too much, for example, problems such as the skin becoming stuffy, proteins denaturing and hair being damaged may occur. Therefore, in conventionally disclosed optical beauty devices, in order to sufficiently lower the temperature of the skin surface or prevent the temperature of the skin surface from rising, many have had to reduce the irradiation intensity of the light. In the optical beauty device 1 of the present disclosure, the skin surface irradiated with light by the light emitting device 2 can be cooled by the air flow supplied by the hair dryer 3. Therefore, while preventing the temperature of the skin surface from rising too much, it is possible to irradiate light with a high intensity that could not be used conventionally.

[0015] Conventionally, there are also light beauty devices that lower the temperature of the member that directly touches the skin surface in order to cool the skin surface. In such light beauty devices, there is a risk of giving discomfort to the user because the skin surface is cooled too much. On the other hand, in the light beauty device 1 of the present disclosure, since an air flow is utilized, it is possible to moderately cool the skin surface, that is, prevent excessive cooling of the skin surface. Therefore, the user can use the light beauty device 1 without feeling discomfort.

[0016] As shown in FIGS. 3 and 4, in the light beauty device 1, the connection leg 215 provided on the light emitting device 2 is inserted into the connection hole 315 provided on the hair dryer 3, and the light emitting device 2 is placed so that the contact surface 214a of the pedestal 214 of the light emitting device 2 follows the upper surface of the hair dryer 3. Thereby, the light emitting device 2 can be attached to the hair dryer 3. Note that as long as the light emitting device 2 can be stably attached to the hair dryer 3, the shape for attaching the light emitting device 2 to the hair dryer 3 is not limited to the shape shown in FIG. 3. For example, instead of providing the pedestal 214, two sets of the combination of the connection leg 215 and the connection hole 315 may be arranged side by side in the front-rear or left-right direction. Further, instead of inserting the connection leg 215 into the connection hole 315 from above, for example, the connection leg may be inserted into a connection groove extending in the front-rear direction by sliding (sliding), and the light emitting device 2 and the hair dryer 3 may be fitted and connected, or the connection portion of the light emitting device 2 and the connection portion of the hair dryer 3 may be connected by magnetic force.

[0017] When using the light beauty device 1, the user holds, for example, the grip cover 311b of the hair dryer 3, and uses it by applying the front end portion of the wall portion 212a, which is a member protruding forward in the light emitting device 2, to the skin surface. By using it in this way, as will be described in detail below, it is possible to accurately perform an operation of cooling the skin surface by the air flow supplied by the hair dryer 3 while irradiating the skin surface with the light emitted by the light emitting device 2.

[0018] <Light emitting device 2> Next, the configuration of the light-emitting device 2 will be described. The light-emitting device 2 can be used as a light beauty device with a blowing function together with the hair dryer 3, or can be used alone as a light beauty device. The light-emitting device 2 has an exterior member 21 and various electrical components housed inside the exterior member 21. The exterior member 21 preferably has a sealed structure. Thereby, the light-emitting device 2 has waterproof and dustproof performance and can protect the electrical components housed inside it.

[0019] Among the exterior member 21, the main body cover 211, the front cover 212, and the rear cover 213 are made of a material with high thermal conductivity and low weight, such as a light alloy such as an aluminum alloy, a magnesium alloy, a titanium alloy, or a copper alloy. Therefore, the heat generated by the electrical components (such as the LED 224, the battery 28, and the control board 29 described later) housed inside the exterior member 21 can be efficiently released outside the light-emitting device 2. Thereby, while increasing the intensity of the light (the output of the LED 224) irradiated by the light-emitting device 2 on the skin surface, it is easy to simplify the heat dissipation mechanism. That is, it is easy to provide a light-emitting device 2 that is small and lightweight while improving the beauty effect by light. The main body cover 211, the front cover 212, and the rear cover 213 are particularly preferably made of a light alloy. Thereby, the light-emitting device 2 can easily balance both mechanical strength and lightness, and can exhibit good waterproof performance and usability. In particular, by ensuring the waterproof performance, it is easy to use the light-emitting device 2 in a wet space such as a bathroom.

[0020] Below the main body cover 211, a pedestal 214 and a connection leg 215 are provided. The contact surface 214a of the pedestal 214 is a surface that contacts the hair dryer 3 and is curved along the upper surface of the hair dryer 3. The connection leg 215 has a function of positioning the light-emitting device 2 with respect to the hair dryer 3 and is fitted into the connection hole 315 of the hair dryer 3 when the pedestal 214 is placed on the upper surface of the hair dryer 3. A contact point 215a1 is provided on the bottom surface 215a of the connection leg 215.

[0021] As shown in FIG. 2, the rear cover 213 is provided with a power button 213a and a power socket 213b. When the user presses the power button 213a, the power of the light-emitting device 2 is turned on. The power socket 213b can charge the light-emitting device 2 by inserting a power cord (not shown). The power socket 213b has a waterproof structure (not shown) inside.

[0022] The front cover 212 has an opening 212b which is a region through which the light emitted from inside the light-emitting device 2 passes, and a wall portion 212a which is provided so as to surround the opening 212b and protrudes forward. The wall portion 212a is provided so as to surround the direction in which the light passes, that is, in a direction orthogonal to the irradiation direction of the light. Thereby, the wall portion 212a is configured to be able to regulate the diffusion of light in a direction orthogonal to the irradiation direction of the light. By having such a wall portion 212a, the light can be concentrated on the skin surface located in the irradiation direction of the light, so that an improvement in the irradiation effect on the skin surface to which the light is to be applied can be expected. Furthermore, it is possible to prevent light from leaking to the surroundings other than the skin surface to which the light is to be applied. Thereby, it is possible to prevent light from entering the eyes of the user himself or other people around, and for example, the light beauty device 1 or the light-emitting device 2 can be used safely even in a shared space such as a household washroom. Note that the opening 212b is closed by a lens 221 which will be described later.

[0023] Specifically, the wall portion 212a is preferably configured to be able to irradiate a skin surface with an area of about 4 cm 2 or more and 20 cm 2 or less, about 5 cm 2 or more and 15 cm 2 or less, or about 6 cm 2 or more and 10 cm 2 or less at a time. By setting it in this way, for example, it is possible to selectively irradiate light on a concerned area such as a part in the hair parting or the hairline on the forehead. Therefore, it is possible to expect to perform an effective treatment in a short time. On the other hand, the wall portion 212a is 10 cm 2It may be configured to be able to irradiate a skin surface area of the above degree at once. In this case, since light can be irradiated onto a wide area of the skin surface at once, there is an advantage that irradiation can be completed in a short time, for example, when it is desired to apply light to the entire scalp.

[0024] Also, the wall portion 212a also has a function of defining the distance from the opening (light emitting means) 212b to the skin surface by protruding forward. That is, it is possible to prevent the skin surface from being irradiated with too strong light due to bringing the opening 212b too close to the skin surface, or the temperature of the skin surface from rising too much. Furthermore, below the wall portion 212a, that is, on the hair dryer 3 side of the wall portion 212a, a notch portion 212a1 through which the air flow supplied by the hair dryer 3 can pass is provided. By supplying the air flow that has passed through this notch portion 212a1 to the inside of the wall portion 212a, that is, to the skin surface being irradiated with light, it is possible to simultaneously perform irradiation of light on the skin surface and cooling by the air flow.

[0025] When the user uses the light beauty device 1 or the light emitting device 2, the front end portion of the wall portion 212a is brought into contact with the skin surface. At this time, since the wall portion 212a is made of an elastic material, it is possible to absorb the impact when contacting the skin surface. Thereby, physical damage to the skin surface can be preferably suppressed. Examples of the elastic material include rubber materials such as silicone rubber, fluorine rubber, and natural rubber, and resin materials having elasticity such as silicone resin. In particular, a medical grade silicone resin is preferably used. In this case, the wall portion 212a can be brought into soft contact with the skin surface. Also, by using a medical grade silicone resin with high chemical resistance, even if hair oil, lotion, etc. remaining on the skin surface adhere to the wall portion 212a, it is easy to prevent or suppress deterioration of the wall portion 212a.

[0026] Note that the wall portion 212a does not necessarily have to be composed only of an elastic material, and its whole or a part thereof may be composed of an elastic material and a rigid material (for example, a rigid resin material, a metal material, a ceramic material, etc.). For example, the wall portion 212a may be configured by coating a rigid material with an elastic material. Further, the rear portion (the side of the opening 212b) of the wall portion 212a may be composed of a rigid material, and the front portion (the skin surface side) thereof may be composed of an elastic material. Furthermore, a rigid portion composed of a rigid material may be provided on the inner peripheral side or the outer peripheral side of the wall portion 212a. In this case, the tip of the rigid portion is arranged so as to be located rearward (the side of the opening 212b) than the front end of the wall portion 212a. The rigid portion may be a wall portion arranged along the circumferential direction of the wall portion 212a, or may be a protrusion portion arranged in a part of the circumferential direction of the wall portion 212a. With the above configuration, even if the elastic portion in contact with the skin surface contracts and deforms, it is possible to prevent the skin surface from approaching the opening 212b (LED 224) beyond the rigid portion.

[0027] When both of the pair of contact portions (contact means) 212a2 of the wall portion 212a come into contact with an object such as the skin surface and are pressed rearward, the contact of the wall portion 212a with the skin surface is detected by the contact detection mechanism 23 arranged in the light emitting device 2. As shown in FIG. 1 and the like, the contact portion (contact means) 212a2 sandwiches the opening (light emitting means) 212b in the left-right direction and is arranged in the vicinity (so as to be close or adjacent). Note that the number of the contact portions 212a2 is not particularly limited as long as it is two or more. For example, in addition to the pair of contact portions 212a2 provided on the left and right of the opening 212b, a pair of contact portions 212a2 may also be provided vertically.

[0028] The light emitting device 2 has an intermediate accommodation portion 25 inside thereof. The intermediate accommodation portion 25 has an accommodation lid 251 and an accommodation body 252, and stably and compactly accommodates the temperature sensor 20, the light emitting portion 22, and the contact detection mechanism 23. As shown in FIGS. 1 and 4, the front end side of the temperature sensor 20 is exposed to the outside through a hole 251c provided in the housing lid 251 and a hole 212c provided in the front cover 212. The temperature sensor 20 is, for example, a radiation temperature sensor or the like, and is a non-contact temperature sensor capable of measuring the temperature of the skin surface by measuring the intensity of infrared rays, visible light, or the like radiated from the skin surface.

[0029] The light emitting unit 22 includes a support 223 fitted into the lens frame 251g of the housing lid 251 from the rear, a plurality of LEDs (light emitting elements) 224 collectively provided on the support 223, a lens 221 fitted into the lens frame 251g from the front, and a lens cover 222. In the housing lid 251, the plurality of LEDs (light emitting elements) 224 on the support 223 are arranged so as to be inclined with respect to the air outlet 312a (front cover 312) of the hair dryer 3. As a result, the air flow supplied from the air outlet 312a easily passes through the notch 212a1, so that both light and air flow can be effectively supplied to the skin surface. Specifically, it is preferable that the support 223 is inclined with respect to the air outlet 312a by about 3° or more and 45° or less, about 5° or more and 30° or less, or about 10° or more and 20° or less. Here, the dashed-dotted line A in FIG. 1 is a straight line orthogonal to the support 223, and the dashed-dotted line B is a straight line orthogonal to the air outlet 312a (front cover 312). Therefore, the angle θ between the dashed-dotted lines A and B is equal to the angle at which the support 223 is inclined with respect to the air outlet 312a (front cover 312).

[0030] The wavelength of the light emitted by the LED (light emitting means) 224 may be about 600 nm or more and 850 nm or less. That is, the light emitting device 2 may irradiate the skin surface with light including red light. Thereby, for example, effects such as promotion of hair growth and promotion of epidermal turnover can be expected. Note that the wavelength of the light emitted by the LED (light emitting means) 224 is not limited to this, and may be longer than 490 nm and about 525 nm or less. That is, the light emitting device 2 may irradiate the skin surface with light including green light. Thereby, for example, an effect of suppressing melanin production can be expected. In addition, the LED (light emitting means) 224 may be configured to irradiate the skin surface with red light and green light simultaneously or alternately, or may be configured to irradiate the skin surface with light of other wavelengths having a beauty effect.

[0031] The intensity of the light emitted by the light emitting means (LED 224) 2 is 6 mW / cm 2 or more, 100 mW / cm 2 or more, 150 mW / cm 2 or more, 200 mW / cm 2 or more, 250 mW / cm 2 or more, or 300 mW / cm 2 or more, which is preferable. Thereby, since light of sufficient intensity can be applied to cells such as hair follicles and dermis, for example, effects such as promotion of hair growth and improvement of skin condition can be expected. The intensity of the light emitted by the LED 224 is particularly 250 mW / cm 2 or more and 300 mW / cm 2 or less, it is easy to balance safety and beauty effects. In addition, on the support 223, instead of or together with a plurality of LEDs 224, for example, a fluorescent lamp, an HID lamp, a krypton lamp, a xenon lamp, a laser element, etc. may be provided. Furthermore, the light source provided in the light emitting device 2 does not necessarily have to be plural, and may be a single light source as long as it can apply light of the required intensity to the skin surface.

[0032] The light emitted by the LED 224 passes through the lens 221 provided in front of the LED 224. The lens 221 is fitted into the lens frame 251g together with the support 223 and is fixed to the lens frame 251g and the front cover 212 by the lens cover 222. The lens cover 222 is in close contact with the outer periphery of the lens frame 251g and the inner periphery of the opening 212b, and prevents the lens 221 from falling off and water from entering the inside of the light emitting device 2. Since the lens 221, the opening 251f, the opening 222a of the lens cover 222, and the opening 212b are positioned, the light that has passed through the lens 221 is emitted out of the light emitting device 2 from the opening 212b and irradiates the skin surface.

[0033] The contact detection mechanism 23 includes a pair of waterproof cones 231, a pair of touch pins 232, a sensor cover 233 having a pair of telescopic protrusions 233b, and a touch sensor 234 having a pair of detection portions 234b. When the contact portion 212a2 of the wall portion 212a is pressed rearward, the waterproof cone 231 located inside (rearward) the contact portion 212a2 is also pressed.

[0034] The waterproof cone 231 is tightly fitted into the hole 251b of the accommodation lid 251, thereby preferably preventing water from entering the inside of the light emitting device 2. By expanding and contracting, the waterproof cone 231 moves the touch pin 232 disposed inside thereof rearward. The rearwardly moved touch pin 232 presses the telescopic protrusion 233b of the sensor cover 233 rearward. The sensor cover 233 is configured to reliably prevent the intrusion of water, dust, etc. into the touch sensor 234. When the telescopic protrusion 233b is pressed rearward by the touch pin 232, it is configured to transmit the pressing force from the touch pin 232 to the detection portion 234b of the touch sensor 234 by contracting rearward.

[0035] Note that the number of each of the waterproof cone 231, the touch pin 232, the telescopic protrusion 233b, and the detection portion 234b is not limited to 2, and can be appropriately set according to the number of the contact portions 212a2. Such a light emitting portion 22 and a contact detection mechanism 23 are fixed to the intermediate accommodation portion 25 by screws 25a. The screw 25a is screwed into the hole 252a of the housing 252 through the hole 251a of the accommodation lid 251, the hole 233a of the sensor cover 233, and the hole 234a of the touch sensor 234.

[0036] A heat sink 24 is disposed behind the support 223 of the light emitting portion 22. The heat sink 24 is fixed to the accommodation lid 251 by a mount plate 24d. Specifically, a screw 24d2 is screwed into a hole (not shown) of the accommodation lid 251 through the hole 24d1 of the mount plate 24d. The heat receiving surface 24a of the heat sink 24 receives the heat generated by the LED 224 via the support 223 by being in close contact with the back surface of the support 223. This heat is transmitted to the heat dissipation fins 24b provided on the back side of the heat sink 24, and then transmitted from the heat dissipation fins 24b to the air in the ventilation holes 26a of the duct 26 provided behind the heat sink 24.

[0037] The light emitting device 2 further includes a battery 28, a control board 29, and a fan 27 inside thereof. The battery 28 stores the electric power supplied from a commercial power source or the like through the power supply hole 213b provided in the rear cover 213, and can supply electric power to the entire light emitting device 2. The control board 29 controls the operation of the entire light emitting device 2, and is configured to detect the connection of the hair dryer 3 or communicate with the hair dryer 3 via the contact 215a1. The fan 27 has a function of collecting the heat generated by the battery 28 and the control board 29 and the heat of the air in the ventilation holes 26a. Specifically, when the blades 271 of the fan 27 rotate, air is sucked into the ventilation holes 27a from the front and rear directions and exhausted in the direction of the arrow in FIG. 5 (downward). The heat of the exhausted air is absorbed by the main body cover 211 having a high thermal conductivity as described above and quickly released to the outside. Thus, since the light emitting device 2 does not require an exhaust heat hole, an excellent waterproof and dustproof structure can be configured.

[0038] <Hair dryer 3> Next, the hair dryer 3 will be described. The hair dryer 3 can be used as a light beauty device 1 together with the light emitting device 2 or as a blower device alone. When simply wanting to dry the hair, the hair dryer 3 can be used with the light emitting device 2 removed to reduce the weight. The hair dryer 3 includes an exterior member 31 and various electrical components housed inside the exterior member 31. The exterior member 31 includes a main body cover 311, a front cover 312, and a rear cover 313.

[0039] As shown in FIG. 2, the rear cover 313 has an air inlet 313a for sucking outside air into the hair dryer 3. Further, as shown in FIG. 1, the front cover 312 has an air outlet 312a for supplying an air flow from inside the hair dryer 3 to the outside. The air inlet 313a and the air outlet 312a are not limited to the illustrated shapes, and any shape can be used as long as these functions can be achieved. The front cover 312 has a shape that surrounds the periphery of the air outlet 312a and protrudes forward. This prevents the air flow supplied from the air outlet 312a from spreading and makes it easy to shape it linearly, so that hair or the like can be dried quickly.

[0040] On the other hand, on the upper side of the front cover 312, that is, on the side where the light emitting device 2 is mounted, a notch 312b through which the air flow supplied from the air outlet 312a can pass is provided. The air flow that has passed through the notch 312b passes through a notch 212a1 provided in the wall portion 212a of the light emitting device 2 and is supplied to the inside of the wall portion 212a. Thereby, an air flow can be supplied to and cooled on the skin surface inside the wall portion 212a, that is, the skin surface irradiated with light. In this way, the notch 312b and the notch 212a1 are secured as a passage capable of supplying a sufficient air flow into the wall portion 212a. Therefore, according to the light beauty device 1, the temperature of the skin surface can be sufficiently cooled to, for example, 53° C. or lower or 44° C. or lower, so that even when strong light is irradiated, an excessive rise in the temperature of the skin surface can be prevented. Therefore, it is possible to expect a high beauty effect while preventing skin troubles due to an increase in the temperature of the skin surface.

[0041] The main body cover 311 is composed of an air passage cover 311a and a grip cover 311b. The air passage cover 311a forms an air passage from the air inlet 313a until the air flow is supplied from the air outlet 312a. On the upper surface of the air passage cover 311a, a connection hole 315 into which the connection leg 215 of the light-emitting device 2 is inserted is provided. On the bottom surface 315a of the connection hole 315, a contact 315a1 that can detect the mounting of the light-emitting device 2 or communicate with the light-emitting device 2 by coming into contact with the contact 215a1 of the connection leg 215 is arranged. The hair dryer 3 may further have a lid body that can be fitted into the connection hole 315. The lid body is configured to be attachable to the connection hole 315 when the light-emitting device 2 is not attached to the hair dryer 3. Thereby, it is possible to prevent foreign matter from entering the hair dryer 3 (connection hole 315).

[0042] The grip cover 311b is a portion that can be gripped by the user. An interface portion 314 is provided on the front surface of the grip cover 311b. The interface portion 314 has a power button 314a, a warm air button 314b, and a cold air button 314c provided at positions where the user can easily press them. The power button 314a can turn on the power of the hair dryer 3 when pressed. The warm air button 314b and the cold air button 314c are buttons for making the air flow supplied from the air outlet 312a into warm air and normal temperature air (cold air) when pressed. The configuration of the interface portion 314 is not limited to this, and in addition to the buttons 314a, 314b, 314c, or instead of these, it may have other buttons such as an air volume change button for changing the air volume, or it may have a touch panel. At the lower end of the grip cover 311b, a power cord 34 for supplying power to the hair dryer 3 from a commercial power supply or the like is provided.

[0043] As shown in FIG. 6, inside the hair dryer 3, a motor 32, a control board 39, and a heater 35 are arranged. The motor 32 sucks outside air from the air inlet 313a of the rear cover 313 and generates an air flow by rotating the impeller 33 provided at the rear thereof. The heater 35 is configured to be able to heat the air flow generated by the motor 32 and passing through the air duct cover 311a. The heater 35 is connected to the connection portion 351 via the fitting portion 35a, and the connection portion 351 is fixed to the air outlet 312a of the front cover 312. The warm air, which is the air flow heated by the heater 35, or the air flow that remains at room temperature without being heated is supplied to the skin surface through the air outlet 312a. The control board 39 controls the operation of the entire hair dryer 3, and is configured to be able to detect the attachment of the light emitting device 2 or communicate with the light emitting device 2 via the contact point 315a1.

[0044] <Control means> Next, the control performed in the optical beauty device 1 will be described. The control board 29 and the control board 39 function as the control means of the optical beauty device 1. FIG. 7 is a block diagram showing the configuration of the control board of the light emitting device and the control board of the hair dryer. The control board 29 of the light emitting device 2 includes a control unit 291, a temperature detection unit 292, a contact detection unit 293, a timing timer 294, a notification unit 295, a light emission control unit 296, and a communication unit 297. The control unit 291 processes and controls the overall operation related to the light-emitting device 2. The control unit 291 is, for example, a processing circuit (not shown). The temperature detection unit (temperature detection means) 292 detects the temperature of the skin surface measured by the temperature sensor 20. The contact detection unit (contact determination means) 293 determines whether or not the pair of contact parts (contact means) 212a2 are in contact with the skin surface (object). The timing timer 294 measures the time elapsed since the LED 224 emitted light. The notification unit 295 causes, for example, a diaphragm (not shown) to vibrate to generate a buzzer sound. Note that the notification unit 295 only needs to be able to issue a notification to the user, and may cause, for example, the blinking of the light emitted by the LED 224, the stop of the light irradiation by the LED 224, vibration caused by vibrating a vibrator, etc. The light emission control unit 296 controls the LED 224, such as the irradiation and stop of the light of the LED 224 and the adjustment of the intensity. The communication unit (attachment / detachment detection means) 297 is configured to be able to detect that the hair dryer 3 has been attached or detached via the contact point 215a1.

[0045] Based on the detected temperature of the skin surface notified by the temperature detection unit 292, the control unit (control means) 291 causes at least one of the irradiation intensity, irradiation pattern, and wavelength of the light emitted by the LED (light-emitting means) 224 to be changed. The control unit 291 may change at least one of them so that the detected temperature becomes 53°C or lower, or 44°C or lower. Thereby, it is possible to more reliably prevent or suppress the skin surface from being overheated and the user from feeling pain or suffering burns. For example, when the temperature of the skin surface exceeds 53°C, the control unit 291 controls the power supply to the LED 224 by the light emission control unit 296 so as to reduce the irradiation intensity of the light emitted by the LED 224, make the irradiation pattern intermittent irradiation, and increase the wavelength. Alternatively, when the temperature of the skin surface exceeds 44°C but is 53°C or lower, the control unit 291 controls the power supply to the LED 224 by the light emission control unit 296 so that the irradiation pattern of the light emitted by the LED 224 is intermittent irradiation and the irradiation intensity and wavelength are not changed. This combination of temperature and control is merely an example, and at least one of the irradiation intensity, irradiation pattern, and wavelength of the light emitted by the LED 224 may be changed so as to lower the temperature of the skin surface.

[0046] On the contrary, when the detected temperature of the skin surface notified from the temperature detection unit 292 is lower than 53°C or 44°C, the control unit 291 may control the light emission control unit 296 so that at least one of an increase in the irradiation intensity of light, a change from intermittent irradiation to continuous irradiation, and a change to a shorter wavelength is executed. In such a manner, when the temperature of the skin surface rises, the amount of light irradiated onto the skin surface can be suppressed. Therefore, skin troubles caused by the skin surface temperature rising too much can be more effectively prevented. On the contrary, when the temperature of the skin surface has not risen, the effect such as hair growth can be increased by increasing the amount of light. That is, while preventing both overheating of the skin surface and insufficient light intensity, high-intensity light can be applied to the skin surface, so high effects can be expected even with short-term use.

[0047] Further, the control unit (control means) 291 is configured to issue a notification to the user of the light beauty device 1 based on the elapse of a predetermined time since the LED (light emission means) 224 notified from the timing timer 294 starts irradiating light. Specifically, when a predetermined time elapses since the LED 224 starts irradiating light, the control unit 291 causes the notification unit 295 to issue a notification to the user. The predetermined time may be set, for example, to about 2 seconds or more and 10 seconds or less, about 3 seconds or more and 8 seconds or less, or about 4 seconds or more and 6 seconds or less. Note that the predetermined time does not have to be fixed. For example, based on the irradiation intensity of the light emitted by the LED 224, the time during which sufficient-intensity light can be applied to the skin surface may be calculated, and the calculated time may be set as the predetermined time.

[0048] By the notification unit 295 notifying the user of the elapse of a predetermined time, the user can know that the skin surface has been irradiated with sufficient light. Then, the user can terminate the irradiation of light on the skin surface without worrying about insufficient light irradiation, and can then start irradiating light on the skin surface where the user wants to apply light next. Also, it is possible to prevent continuously irradiating light on a specific part of the skin surface for a long time, and the user can use the light beauty device 1 without worrying about skin troubles or the like caused by long-term irradiation. Furthermore, since the time for using the light beauty device 1 is short, it becomes even easier to get used to the daily use of the light beauty device 1.

[0049] Furthermore, the control unit 291 receives a notification from the contact detection unit 293 as to whether or not the contact portion 212a2 has contacted an object. The contact detection unit (contact determination means) 293 determines that the pair of contact portions (contact means) 212a2 has contacted the object when both of the pair of detection portions 234b of the touch sensor 234 are sufficiently pressed, that is, when it is determined that both (all) of the pair of contact portions (a plurality of contact portions) 212a2 have contacted the skin surface (object). When receiving a "no" notification from the contact detection unit 293, the control unit 291 causes the light emission control unit 296 to stop irradiating light from the LED 224. In other words, when the contact detection unit (contact determination means) 293 determines that the pair of contact portions (contact means) 212a2 is not in contact with the object, the control unit (control means) 291 prohibits (does not allow) the LED (light emission means) 224 from irradiating light.

[0050] Thereby, for example, when the wall portion 212a is not in contact with the skin surface, or when only one of the pair of contact portions 212a2 is pressed because the wall portion 212a is in contact with the skin surface while being inclined, it is possible to prevent the LED 224 from emitting light. In this way, when the wall portion 212a is not in sufficient contact with the skin surface, the LED 224 does not emit light, so that the risk of light entering the eyes of the user or the like can be preferably avoided.

[0051] Further, the control unit 291 receives a notification from the communication unit 297 as to whether or not the hair dryer 3 is attached. When the control unit (light emitting means) 291 receives (detects) from the communication unit (attachment / detachment detection means) 297 that the hair dryer (cooling means) 3 is not attached, it restricts the function of the LED (light emitting means) 224. Specifically, the control unit 291 controls the light emission control unit 296 to reduce the irradiation intensity of the light emitted by the LED (light emitting means) 224, make the irradiation pattern intermittent irradiation, or change it to a longer wavelength. The control unit 291 may control the light emission control unit 296 to apply all of these changes, or may apply any one or two of the changes. Thereby, when the hair dryer 3 is not attached, that is, when an air flow cannot be supplied to the skin surface, the intensity of the light applied to the skin surface can be reduced. Therefore, even when the hair dryer 3 is not attached, it is possible to suitably prevent or suppress the skin surface temperature from rising too much.

[0052] Note that the communication unit 297 may be configured to be able to transmit information such as the temperature of the skin surface acquired by the light emitting device 2, the presence or absence of contact between the skin surface and the contact portion 212a2, and the elapsed time since the start of light emission of the LED 224 to the hair dryer 3, in addition to detecting the presence or absence of attachment of the hair dryer 3. Further, the communication unit 297 may be configured to be able to receive information from the hair dryer 3. For example, the communication unit 297 may receive whether or not the hair dryer 3 is supplying an air flow and notify the control unit 291. Then, the control unit (control means) 291 may be configured to stop or restrict the light irradiation by the LED (light emitting means) 224 when the hair dryer (cooling means) 3 is not supplying an air flow. According to such a configuration, when the skin surface is not cooled by the air flow, it is possible to prevent or suppress applying strong light to the skin surface. Therefore, it is possible to suitably prevent the skin surface temperature from rising too much.

[0053] The control board 39 of the hair dryer 3 includes a control unit 391, an operation detection unit 392, a temperature control unit 393, a rotation control unit 394, and a communication unit 395. The control unit 391 processes and controls the overall operations related to the hair dryer 3. The control unit 391 is, for example, a processing circuit (not shown). The operation detection unit 392 detects whether any of the interface units 314 has been operated. The temperature control unit 393 controls the output to the heater 35 to adjust the temperature of the air flow. The rotation control unit 394 controls the rotation of the motor 32 to adjust the wind speed (air volume) of the air flow. The communication unit (attachment / detachment detection means) 395 is configured to be able to detect that the light emitting device 2 has been attached or detached via the contact 315a1.

[0054] The control unit 391 controls the temperature control unit 393 based on the operation on the interface unit 314 notified by the operation detection unit 392. For example, when notified that the warm air button 314b has been pressed, the control unit 393 operates the heater 35 and controls so that warm air is supplied from the air outlet 312a. Also, when notified that the cold air button 314c has been pressed, the control unit 393 stops the heater 35 and controls so that an air flow at room temperature is supplied from the air outlet 312a. Note that the hair dryer 3 may further have a cooling element such as a Peltier element, and when the cold air button is pressed, a current may flow through the cooling element and be configured to cool the air flow. Also, when the interface unit 314 has an air volume change button, when the control unit 391 is notified that the air volume change button has been pressed, the control unit 391 increases or decreases the rotation speed of the motor 32 in the rotation control unit 394, and increases or decreases the wind speed (air volume) of the air flow supplied from the air outlet 312a. The wind speed of the air flow can be changed in three steps, for example, to about 1 m / s or more, about 5 m / s or more, and about 10 m / s or more.

[0055] When the control unit 391 is notified by the communication unit 395 that the light-emitting device 2 is mounted and the light-emitting device 2 is operating, the control unit 391 stops the heater 35 in the temperature control unit 393 and rotates the motor 32 in the rotation control unit 394. That is, the control unit (control means) 391 operates the hair dryer (cooling means) 3 so as to cool the skin surface irradiated with light from the light-emitting device 2 by an air flow. Thereby, it is possible to prevent hot air from being supplied to the skin surface irradiated with light and prevent the air flow from not being supplied. For this reason, it is possible to prevent or suppress the temperature of the skin surface from rising too much. In this case, the air flow supplied to the skin surface may be continuous, intermittent, or a combination thereof.

[0056] The communication unit 395 may be further configured to receive from the light-emitting device 2 whether or not the irradiation of light has started and notify the control unit 391. In this case, even when the light-emitting device 2 is mounted, the control unit 391 does not stop the heater 35 in the temperature control unit 393 when the irradiation of light has not started. Then, when the irradiation of light starts, the temperature control unit 393 is controlled to stop the heater 35. Thereby, with the light-emitting device 2 mounted, the hair dryer 3 can be used as a normal hair dryer, and when starting to be used as the light beauty device 1, the skin surface can be surely cooled by the air flow.

[0057] By performing the above control, the light beauty device 1 can irradiate sufficient light while preventing the skin surface from becoming too hot. Hereinafter, a modified example of the above-described light beauty device 1 will be described. The above-described embodiment and the following modified examples can be combined with each other.

[0058] In the foregoing embodiment, it has been described that the optical beauty device 1 determines whether or not the pair of contact portions (contact means) 212a2 are in contact with the skin surface (object). However, the optical beauty device 1 may be configured to determine the distance between the skin surface (object) and the LED 224 instead of or in addition to the determination of the contact. When the skin surface is strongly pressed against the contact portion 212a2, the wall portion 212a made of an elastic material deforms, and the distance between the skin surface and the LED 224 becomes smaller. The optical beauty device 1 may determine the distance between the skin surface and the LED 224 based on the pressing strength against the contact portion 212a2, or may be provided with a separate contact sensor or a distance measurement sensor such as a laser, electrostatic, or LED light, and use this to determine the distance.

[0059] Then, the optical beauty device 1 may be configured to be able to determine the position of the skin surface in order from far (from the front) to the LED 224. The optical beauty device 1 may be configured to be able to detect, for example, a first measurement distance and a second measurement distance. Here, the first measurement distance is the distance between the skin surface and the LED 224 when the approaching skin surface from the front is in close contact with the front end of the wall portion 212a and the light emitted from the light emitting device 2 does not leak from between them. Specifically, when the distance between the skin surface and the LED 224 is the first measurement distance, the skin surface is located, for example, about 5 mm behind the front end of the wall portion 212a in the natural state (state where no external force is applied). That is, the first measurement distance is a distance at which light leakage to the surroundings can be prevented and the air flow supplied between the lens 221 and the skin surface is sufficiently convective with respect to the intensity of the light irradiated on the skin surface. On the other hand, the second measurement distance is the distance between the skin surface and the LED 224 such that the space between the skin surface and the lens 221 (inside the wall portion 212a) is not sufficiently secured. Specifically, when the distance between the skin surface and the LED 224 is the second measurement distance, the skin surface is located, for example, about 5 mm in front of the lens 221. That is, the second measurement distance is a distance at which the air flow cannot be sufficiently convective and the skin surface cannot be sufficiently cooled.

[0060] That is, the arrangement and settings of each part of the optical beauty device 1 are set so that, in order from the front, they are the front end of the wall portion 212a, the position of the skin surface when the first measurement distance is determined, the position of the skin surface when the second measurement distance is determined, the lens 221, and the air outlet 312a. When the optical beauty device 1 determines that the distance between the skin surface and the LED 224 exceeds the first measurement distance, it prohibits the irradiation of light from the LED 224. When the optical beauty device 1 determines that the distance between the skin surface and the LED 224 is equal to or less than the first measurement distance and exceeds the second measurement distance, it allows the irradiation of light from the LED 224. Further, when the optical beauty device 1 determines that the distance between the skin surface and the LED 224 is equal to or less than the second measurement distance, it prohibits or attenuates the irradiation of light from the LED 224, changes the irradiation pattern or wavelength, or enhances or cools the air flow supplied from the air outlet 312a.

[0061] Note that the control performed by the optical beauty device 1 is not limited to the above example. When the skin surface is in close contact with the wall portion 212a to such an extent that light does not leak to the surroundings, the optical beauty device 1 allows the irradiation of light from the LED 224. When the skin surface becomes unnecessarily hot due to the distance between the skin surface and the LED 224 being too close, it may control not to irradiate the skin surface with overly strong light or to increase the degree of cooling of the skin surface. In this way, by stepwise determining the distance between the skin surface and the LED 224 and controlling the irradiation of light or the supply of air flow based on the determination result, the safety of the optical beauty device 1 can be further improved.

[0062] Also, the optical beauty device 1 may be further configured to be able to detect one or more measurement distances. And as the distance between the skin surface and the LED 224 decreases, for example, the intensity of the light irradiated from the LED 224 may be attenuated, the irradiation pattern of the light may be changed to shorten the irradiation time, the irradiated light may be changed to a longer wavelength, the wind speed of the air flow supplied from the air outlet 312a may be increased, etc., and such controls may be performed step by step. The content of the control is not limited to this. Thereby, the safety of the optical beauty device 1 can be further improved. Note that the control based on the detection result of the measurement distance may be performed by either the control unit 291 or the control unit 391, or both may perform it.

[0063] In the above-described embodiment, it has been described that the light-emitting device 2 includes the temperature sensor 20. However, instead of the light-emitting device 2, the hair dryer 3 may include a temperature sensor. In this case, the detected temperature of the skin surface is notified to the control unit 391. Then, the control unit 391 is configured to change at least one of the wind speed, temperature, and wind direction of the air flow supplied by the hair dryer (cooling means) 3 based on the detected temperature of the skin surface. Specifically, for example, when the temperature of the skin surface exceeds 44°C or 53°C, the control unit 391 is configured to change at least one of the wind speed, temperature, and wind direction of the air flow.

[0064] As a method of changing the wind speed of the air flow, the rotation control unit 394 may increase the rotation speed of the motor 32 to increase the wind speed (air volume) of the air flow. As a method of changing the temperature of the air flow, the temperature control unit 393 may stop the heater 35, or when the hair dryer 3 has a cooling element such as a Peltier element, the cooling element may be operated to cool the air flow. Further, as a method of changing the wind direction of the air flow, for example, the angle of the air outlet 312a in the hair dryer 3 may be configured to be changeable, and the angle of the air outlet 312a may be changed so that the air flow is supplied upward (the skin surface irradiated with light).

[0065] Further, both the light-emitting device 2 and the hair dryer 3 may include a temperature sensor. In this case, when the temperature of the skin surface rises, control for cooling the skin surface can be performed by both the light-emitting device 2 and the hair dryer 3, so that overheating of the skin surface can be more efficiently prevented or suppressed. Furthermore, the temperature sensor may be provided in one of the light-emitting device 2 and the hair dryer 3 and configured to be transmitted to the other via the communication unit 297 and the communication unit 395.

[0066] In the foregoing embodiments, the case where both the light-emitting device 2 and the hair dryer 3 include a control unit has been described. However, only one of the light-emitting device (light-emitting means) 2 and the hair dryer (cooling means) 3 may include a control unit (control means). In this case, it is preferable that one of them executes the function as the control unit of the other and is configured to operate each unit via the communication unit 297 and the communication unit 395.

[0067] In the foregoing embodiments, the case where the hair dryer 3 operates as a cooling means has been described. However, the light-emitting device 2 may also include a cooling means. For example, an air outlet may be provided in the front cover 212 of the light-emitting device 2, and a fan may be provided inside the light-emitting device 2, so that both the light-emitting device 2 and the hair dryer 3, or the light-emitting device 2 alone, may be configured to supply an air flow to the skin surface.

[0068] In the foregoing embodiments, it has been described that the light-emitting device 2 and the hair dryer 3 are configured to be able to detect their mutual mounting states (whether they are mounted or not) by the contacts 215a1 and 315a1. However, the method for detecting this mounting is not particularly limited. For example, they may notify each other of their mutual mounting states by wireless communication or a change in magnetic force. Also, only one of the light-emitting device 2 and the hair dryer 3 may be able to detect the mounting state of the other. For example, when only the hair dryer 3 can detect the mounting state of the light-emitting device 2, the hair dryer 3 may detect the mounting state of the light-emitting device 2 by having a switch that is pressed when the light-emitting device 2 is mounted, or may detect the mounting of the light-emitting device 2 by detecting the weight of the light-emitting device 2.

[0069] In the foregoing embodiments, the case where the light-emitting device 2 is located above the air outlet 312a of the hair dryer 3 has been described. However, the light-emitting device 2 may be arranged, for example, laterally or below in the left-right direction of the air outlet 312a. However, it is preferable that the light-emitting device 2 is installed above the hair dryer 3 because a mechanism for preventing the light-emitting device 2 from falling off can be easily configured or omitted.

[0070] In the foregoing embodiments, the light-emitting device 2 has been described as having waterproof and dustproof performance. However, the light-emitting device 2 may not have waterproof and dustproof performance. In this case, the fan 27 does not have to be a sealed fan, and exhaust holes may be provided in the main body cover 211 of the light-emitting device 2. Further, the exterior member 21 may be made of a material with a low thermal conductivity such as resin.

[0071] In the foregoing embodiments, the case where the hair dryer 3 operates as a cooling means has been described. However, the cooling means is not limited to a hair dryer. FIG. 8 is an external view showing an example in which a portable fan operates as a cooling means. A connection hole 315' into which the connection leg 215 of the light-emitting device 2 can be inserted is formed in the upper part of the portable fan 3'. The connection hole 315' preferably has contacts (not shown) on the bottom surface. Note that the cooling means does not have to be the hair dryer 3 or the portable fan 3', and may be an air blower, a body dryer, or the like.
