Description

本発明は、肌の美容のために肌に対して光を照射する光照射美容器具に関するものである。   The present invention relates to a light-irradiated beauty instrument that irradiates light to the skin for skin beauty.

光を照射することで肌の美容を図る光照射美容器具には、照射する光としてレーザー光を用いるもの、低出力の非コヒーレント光を用いるもの等、各種存在しているが、この光照射に際し、皮膚の色を検出して肌の色に応じて光照射時間を制御するもの（特許文献１）があるとともに、皮膚表面の電磁波に対応するインレット信号によって光照射をフィードバック制御するもの（特許文献２）がある。   There are various types of light-irradiated beauty instruments that aim to beautify the skin by irradiating light, such as those that use laser light as the irradiating light and those that use low-power non-coherent light. In addition, there is one that detects the skin color and controls the light irradiation time according to the skin color (Patent Document 1), and the one that performs feedback control of light irradiation by an inlet signal corresponding to the electromagnetic wave on the skin surface (Patent Document 1) 2).

しかし、前者においては光照射中の皮膚の状態変化に応じた光照射制御を行うことができないという問題を有している。また、後者においてはフィードバック制御がなされるとはいえ、皮膚の熱的障害については考えられていない。
特開平５−１４６５１７号公報 特開平９−２８５５２０号公報 However, the former has a problem in that it cannot perform light irradiation control according to changes in the state of the skin during light irradiation.

JP-A-5-146517 JP-A-9-285520

本発明は上記の従来の問題点に鑑みて発明したものであって、熱的障害を招くことがない光照射美容を行うことができる光照射美容器具を提供することを課題とするものである。   The present invention has been invented in view of the above-described conventional problems, and an object of the present invention is to provide a light-irradiated beauty instrument capable of performing light-irradiation beauty without causing thermal failure. .

上記課題を解決するために本発明に係る光照射美容器具は、肌の美容のための光を皮膚に対して照射する光源部と、光源部からの光が照射される皮膚の温度を検出する皮膚温度検知手段と、皮膚温度検知手段で得られた皮膚温度データに基づいて光源部の光出力を制御する制御手段とを備えていることに特徴を有している。光照射による皮膚温度変化に応じて光照射が制御されるものである。   In order to solve the above-mentioned problems, a light-irradiation beauty instrument according to the present invention detects a temperature of a skin to which light from a light source unit is irradiated, and a light source unit that irradiates the skin with light for skin beauty. It is characterized by comprising a skin temperature detection means and a control means for controlling the light output of the light source unit based on the skin temperature data obtained by the skin temperature detection means. Light irradiation is controlled according to the skin temperature change by light irradiation.

上記制御手段には、光源部から出力する光出力をデューティ制御するものを好適に用いることができる。   As the control means, one that performs duty control on the light output output from the light source unit can be suitably used.

また制御手段は、検出された皮膚温度と光照射時間との積算値が所定値に達したならば光出力を低減乃至停止させるものが好ましい。   Further, the control means preferably reduces or stops the light output when the integrated value of the detected skin temperature and the light irradiation time reaches a predetermined value.

環境温度を測定する環境温度検知手段を備えて、制御手段は皮膚温度検知手段の出力と環境温度検知手段の出力とから皮膚温度検知手段が皮膚に接触しているか否かを判断して接触していないと判断された時に光源部からの光出力を停止させるものであってもよい。   An environmental temperature detection means for measuring the environmental temperature is provided, and the control means determines whether or not the skin temperature detection means is in contact with the skin from the output of the skin temperature detection means and the output of the environmental temperature detection means. The light output from the light source unit may be stopped when it is determined that it is not.

皮膚温度検知手段は皮膚温度を非接触で測定する非接触式のものを用いてもよく、更には皮膚を冷却する皮膚冷却手段を備えたものとするのも好ましい。   The skin temperature detecting means may be a non-contact type that measures the skin temperature in a non-contact manner, and further preferably includes a skin cooling means for cooling the skin.

本発明は、光照射による皮膚温度変化に応じて光照射が制御されるために、光照射による熱障害が皮膚に生じてしまうことを避けることができて、光照射による美容効果を安全に行うことができる。   In the present invention, since light irradiation is controlled in accordance with changes in skin temperature due to light irradiation, it is possible to avoid thermal damage caused by light irradiation on the skin, and to safely perform a cosmetic effect due to light irradiation. be able to.

以下、本発明を添付図面に示す実施形態に基いて説明すると、図１は手持ち式の光照射美容器具を示しており、手で持つことができるサイズに形成されているハウジング１の一端側には光源部２と皮膚温度検知手段である温度センサ３とが配設され、ハウジング１内には上記光源部２からの光出力を制御する制御部４と、報知部５とが配設されている。   Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. FIG. 1 shows a hand-held light-irradiating beauty instrument, and is attached to one end side of a housing 1 that is formed in a size that can be held by hand. A light source unit 2 and a temperature sensor 3 as a skin temperature detecting means are arranged, and a control unit 4 for controlling the light output from the light source unit 2 and a notification unit 5 are arranged in the housing 1. Yes.

上記光源部２は、光源２０と、その光照射用開口部に配した光透過性材からなるカバー２１とからなるもので、このカバー２１には、集光や光拡散といったレンズの機能や波長カットの機能をもたせたものを用いることができる。上記光源２０としてはどのようなものを用いるものであってもよいが、ここでは低出力の非コヒーレント光を出力するものを用いている。   The light source unit 2 includes a light source 20 and a cover 21 made of a light-transmitting material disposed in the light irradiation opening. The cover 21 has a lens function and wavelength such as condensing and light diffusion. Those having a cutting function can be used. Although what kind of thing may be used as the said light source 20, what outputs the low output non-coherent light is used here.

また、上記温度センサ３は、上記光照射用開口部の周縁に配置されて光照射用開口部（カバー２１）を皮膚に接触させた時に同時に皮膚に接触して皮膚の温度を検出するもので、図２に示すように、熱電対からなるセンサ部３０とこのセンサ３０を付勢するばね３１とからなり、皮膚に押し当てた時、センサ部３０と皮膚との接触圧がほぼ一定に保たれる。   The temperature sensor 3 is arranged at the periphery of the light irradiation opening and detects the temperature of the skin by simultaneously contacting the skin when the light irradiation opening (cover 21) is brought into contact with the skin. As shown in FIG. 2, the sensor unit 30 is composed of a thermocouple and a spring 31 that biases the sensor 30. When pressed against the skin, the contact pressure between the sensor unit 30 and the skin is kept almost constant. Be drunk.

光を照射したい部分の皮膚に光照射用開口部を押し当ててスイッチを投入すれば、光源部２の光源２０が点灯して皮膚に対する光照射を開始すると同時に、温度センサ３によって皮膚温度を測定し、測定された皮膚温度が例えば５０℃以上であれば、制御部４は光出力を低下させ、５５℃以上であれば光出力を停止させる。   If the light irradiation opening is pressed against the skin where light is to be irradiated and the switch is turned on, the light source 20 of the light source 2 is turned on to start light irradiation on the skin, and at the same time, the skin temperature is measured by the temperature sensor 3. And if the measured skin temperature is 50 degreeC or more, for example, the control part 4 will reduce light output, and if it is 55 degreeC or more, it will stop light output.

また制御部は、上記のような光出力制御に際し、上記報知部５（たとえばスピーカや報知ランプ）を作動させることで、光照射出力を変化させていることを使用者に対して報知する。   In addition, in the light output control as described above, the control unit notifies the user that the light irradiation output is changed by operating the notification unit 5 (for example, a speaker or a notification lamp).

照射完了時は再びスイッチを操作することで、制御部４を介して光源部２や温度センサ３の動作を停止させる。制御部４にタイマー機能を搭載して、使用開始から例えば２０分間で自動的に照射を停止させるようにしても良い。   When the irradiation is completed, the operation of the light source unit 2 and the temperature sensor 3 is stopped via the control unit 4 by operating the switch again. A timer function may be mounted on the control unit 4 so that irradiation is automatically stopped, for example, in 20 minutes from the start of use.

皮膚温度検知は１０秒間隔で行えばよいが、図３に示すように、環境温度を検出する温度センサ８を設けるとともに、皮膚温度検知の間隔を少なくとも１秒以下もしくは常時検出するものとし、検出される皮膚温度が環境温度とほぼ同じとなった時には、光照射出力を停止させるようにしてもよい。光照射用開口部が皮膚から離れた場合、光が漏れ出ることになるとともに、この光で目を痛めることがあるが、この時には光照射が停止されるために、安全性が増すものであり、また、別途安全装置のセンサを追加しなくても誤照射の危険を防ぐことができる。   The skin temperature may be detected at intervals of 10 seconds. However, as shown in FIG. 3, a temperature sensor 8 for detecting the environmental temperature is provided, and the skin temperature detection interval is at least 1 second or less or always detected. When the applied skin temperature becomes substantially the same as the environmental temperature, the light irradiation output may be stopped. If the light-irradiating opening is separated from the skin, light will leak out and this light may hurt your eyes. At this time, the light irradiation is stopped, which increases safety. In addition, the risk of mis-irradiation can be prevented without adding a separate safety device sensor.

また、上記制御部４は、皮膚温度と照射時間とを積算して予め設定された積算値を越えると光照射出力を低減するものであってもよい。圧迫などによって皮膚血流が滞り、この状態で皮膚温度が４５℃を超えた状態が係属すると低温火傷の危険が生じるが、上記積算値による制御を行うことで、熱の蓄積を検出することができて、低温火傷の発生を防ぐことができる。   Moreover, the said control part 4 may reduce light irradiation output, if the skin temperature and irradiation time are integrated and it exceeds the preset integrated value. If the skin blood flow stagnate due to compression or the like, and the state where the skin temperature exceeds 45 ° C. is involved in this state, there is a risk of low-temperature burns. And can prevent the occurrence of low temperature burns.

ところで光照射出力の制御にあたっては、光源部２０に流す電流値を制限したりすることで光出力を低下させるのではなく、図４に示すようにデューティ比制御で行うことが好ましい。例えば１００％の出力で照射していた光照射強度を半減させる場合、点灯１０ｍｓｅｃ、消灯１０ｍｓｅｃを繰り返すデューティ比５０％のパルス点灯により行うのである。光照射中に、光の照射が中断したり、光の照射強度があからさまに低下すると使用者のとしては美容施術を継続する意欲が低減してしまうが、短い周期のパルス点灯では、目の残像現象により連続点灯しているように認識されるためであり、使用者に認識されることなく光照射強度低下を行うことができる。   By the way, in controlling the light irradiation output, it is preferable not to reduce the light output by limiting the value of the current flowing through the light source unit 20, but to perform the duty ratio control as shown in FIG. For example, when the light irradiation intensity irradiated at 100% output is halved, it is performed by pulse lighting with a duty ratio of 50% that repeats lighting 10 msec and lighting 10 msec. During light irradiation, if the light irradiation is interrupted or the light irradiation intensity decreases clearly, the user's willingness to continue the cosmetic treatment will be reduced. This is because it is recognized as being continuously lit due to the phenomenon, and the light irradiation intensity can be reduced without being recognized by the user.

皮膚温度検出手段としては、皮膚に対して非接触で検出することができるもの、例えば赤外線放射センサを用いてもよい。図５はこのような非接触式温度センサ３を用いた光照射美容器具の一例を示しており、図中９は人体を示している。机上などに置いた状態で用いられる本体部１０に対して光源部２は可動式アーム１１でその光照射方向が可変となっていて、使用者は任意の姿勢で光源部２からの光照射を顔面等の皮膚に受けることができる。なお、上記温度センサ３は光源部２の表面に配設されている。可動式アーム１１を介さずに本体部１０に対して光源部２を角度調整自在に取り付けたものであってもよい。   As the skin temperature detecting means, a device that can detect the skin without contact, for example, an infrared radiation sensor may be used. FIG. 5 shows an example of a light irradiation beauty instrument using such a non-contact temperature sensor 3, and 9 in the figure shows a human body. The light source unit 2 is a movable arm 11 with respect to the main body unit 10 used in a state of being placed on a desk or the like, and its light irradiation direction is variable, and the user can irradiate light from the light source unit 2 in an arbitrary posture. Can be received on the skin such as the face. The temperature sensor 3 is disposed on the surface of the light source unit 2. The light source unit 2 may be attached to the main body unit 10 so as to freely adjust the angle without using the movable arm 11.

図６に示すものは、前記図１に示したものにおいて、皮膚を冷却するための冷却手段６を光照射用開口部の付近に設けたものを示している。皮膚の高温状態が検知された場合、冷却手段７によって皮膚を冷却することができるために、光照射の停止や光照射出力を低減したりしなくても、皮膚の熱障害を防ぐことができる。なお、皮膚に接触して皮膚を冷却する冷却手段６としては、ペルチェモジュールを用いることができる。   FIG. 6 shows that shown in FIG. 1 in which a cooling means 6 for cooling the skin is provided in the vicinity of the opening for light irradiation. Since the skin can be cooled by the cooling means 7 when a high temperature state of the skin is detected, it is possible to prevent thermal damage to the skin without stopping light irradiation or reducing the light irradiation output. . A Peltier module can be used as the cooling means 6 that cools the skin in contact with the skin.

皮膚の冷却は、送風によって行ってもよい。図７は図５に示したものにおける光源部２の両脇に送風用ファン６１を配したものを示しており、図８は図１に示したものに送風ファン６１と排気路６２とを設けたものを示している。   The skin may be cooled by blowing air. FIG. 7 shows a structure in which a blower fan 61 is arranged on both sides of the light source unit 2 in the structure shown in FIG. 5, and FIG. 8 shows that the blower fan 61 and the exhaust path 62 are provided in the structure shown in FIG. Is shown.

さらに皮膚の冷却は、ミストを皮膚に供給することで行ってもよい。図９は図５に示したものにおける光源部２の両脇にミスト発生手段６２を配したものを、図１０は図１に示したものにミスト発生手段６２を配したものを示している。このミスト発生手段６２としては、ベンリュリー効果によって吸い上げた水をミスト状にして吐出するもの、ボイラーを備えてスチームミストを吐出するもの、放電によって水をミスト化して吐出するもの、超音波を用いてミストを生成するもの等、どのようなものでもよい。この場合、皮膚の冷却に加えて、皮膚に水分を供給することができるために、皮膚の乾燥を防ぐことができる。   Furthermore, the skin may be cooled by supplying mist to the skin. FIG. 9 shows a structure in which mist generating means 62 is arranged on both sides of the light source unit 2 in the structure shown in FIG. 5, and FIG. 10 shows a structure in which mist generating means 62 is arranged in the structure shown in FIG. As the mist generating means 62, water that has been sucked up by the Ben-Lury effect is discharged in a mist form, a boiler is provided to discharge steam mist, water is discharged as mist by discharge, and ultrasonic waves are used. Anything may be used, such as one that generates mist. In this case, in addition to cooling the skin, moisture can be supplied to the skin, so that drying of the skin can be prevented.

このような皮膚冷却動作は、前記制御部４は前記報知部５をまず作動させて、使用者に対してこれから皮膚冷却動作を行うことを報知するようにしておくのが好ましい。使用者にしてみれば、冷却動作に驚くことがなくなる上に、故障と混同してしまうことがない。   In such a skin cooling operation, it is preferable that the control unit 4 first activates the notification unit 5 to notify the user that the skin cooling operation will be performed. From the user's point of view, the cooling operation is not surprising and is not confused with a failure.
