Description

本発明は、就寝者の睡眠改善を図る照明システムに関する。   The present invention relates to a lighting system for improving sleep of a sleeping person.

人の睡眠状態判定、睡眠評価などを目的として、就寝者の入床から起床までにおける状態を判定する技術が開発されている(特開平5−245148、特開平5−337103、特開平5−95934、特開平5−95935、特開平5−111474、特開平6−98863、特開2000−316832号公報など)。   For the purpose of determining the sleep state of a person, evaluating sleep, etc., techniques for determining the state of a sleeping person from entering the bed to getting up have been developed (Japanese Patent Laid-Open Nos. 5-245148, 5-337103, and 5-95934). JP-A-5-95935, JP-A-5-111474, JP-A-6-98863, JP-A-2000-316832, etc.).

また、夜間に脳から分泌される睡眠促進ホルモン「メラトニン」は光により抑制されることが知られており(非特許文献1参照)、その分泌抑制を低減するための照明装置が開発されている。また、入眠用ランプの照度を計時手段による経時とともに下げるように制御する装置が知られている(特許文献1参照)。   In addition, it is known that the sleep promoting hormone “melatonin” secreted from the brain at night is suppressed by light (see Non-Patent Document 1), and an illumination device for reducing the secretion suppression has been developed. . There is also known an apparatus for controlling the illuminance of the sleep lamp to be lowered with time by a time measuring means (see Patent Document 1).

上記、就寝者の入床から起床までにおける状態を判定する技術においては、ベッド上での体動量を圧電素子センサなどにより検出することにより、ベッド上で最初に検知された大きな体動が生じた時点で「入床」、その後、ベッド上での活動量が一定量以下となった時点で「睡眠」と判定している。   In the above-described technology for determining the state of a sleeping person from getting up to waking up, a large body movement first detected on the bed is generated by detecting the amount of body movement on the bed with a piezoelectric element sensor or the like. It is determined to be “sleeping” at the time of “entering the bed” at the time, and then when the amount of activity on the bed falls below a certain amount.

就寝時における睡眠にかけての就寝者の状態情報は、以下の2つの技術へ応用可能である。一つは、上記のメラトニン分泌抑制低減照明の制御への応用である。メラトニンは夜間の比較的遅い時間帯から分泌が開始されるため、夜間のある時刻を境として、従来の一般照明からメラトニン分泌抑制低減照明へと切り替えを行う必要がある。具体的には、就寝時刻の約2時間前、もしくは、起床時刻の14時間後からメラトニン分泌が顕著になることが示されており(非特許文献2参照)、それに合わせて、従来の一般照明からメラトニン分泌抑制低減照明へと切替えることが妥当であると思われるが、ユーザが自らの就床時刻を考慮して手動で切替えを行うことは、利便性に欠ける。従って、ユーザの就寝・起床時刻を検出して自動的に上記照明の切替えを行うことで、ユーザがその切替えを意識することなく、最適な照明環境を提供することが求められている。   The information on the sleeper's status during sleep at bedtime can be applied to the following two technologies. One is application to the control of the above-mentioned melatonin secretion suppression reduction lighting. Since melatonin starts to be secreted from a relatively late night time, it is necessary to switch from conventional general lighting to melatonin secretion-inhibiting reduced lighting at a certain time of the night. Specifically, it has been shown that melatonin secretion becomes prominent about 2 hours before bedtime or 14 hours after wake-up time (see Non-Patent Document 2). However, it is not convenient for the user to manually switch in consideration of his / her bedtime. Therefore, it is required to provide an optimal lighting environment by detecting the user's sleep / wake-up time and automatically switching the above-mentioned lighting without the user being aware of the switching.

もう一つは、睡眠評価への応用である。入眠が円滑かどうかは睡眠の健康度を表する一つの要素であると言え、その「入眠の円滑さ」を定量化することで、ユーザは睡眠の健康度の目安とすることができる。その定量化方法としては、入眠できるまでに要した時間(一般に、「睡眠潜時」と呼ばれている)の計測が容易であり、その測定には、ユーザが眠ろうとする意識を抱いた時刻情報と、実際に眠りについた時刻情報が必要となる。前者の時刻情報を取得するために、上述の特開平5−245148号などでは、入床のタイミングの検出を行っているが、実生活においては入床後に読書をしたり、テレビを見たりする場合も多いため、入床のタイミングをユーザが眠ろうとする意識を抱いたタイミングとするのは問題があり、これにより算出された睡眠潜時は正確でない。

Behav Sleep Med. 2003;1(2);102−14
The other is application to sleep evaluation. It can be said that whether sleep is smooth or not is one element that represents the health level of sleep. By quantifying the “smoothness of sleep”, the user can use it as a measure of the health level of sleep. As a quantification method, it is easy to measure the time required to fall asleep (generally referred to as “sleep latency”), and the time at which the user is conscious of going to sleep is included in the measurement. Information and time information about actually falling asleep are required. In order to obtain the former time information, the above-mentioned Japanese Patent Laid-Open No. 5-245148 etc. detects the timing of entering the floor, but in real life, reading or watching TV after entering the floor. Since there are many cases, there is a problem in setting the timing of entering the bed to the timing when the user is conscious of going to sleep, and the sleep latency calculated thereby is not accurate.

上記2つの応用を可能とするために、ユーザが眠ろうとする意識を抱いたタイミングを容易、かつ、より正確に検出する手段を提供する必要がある。そこで、本発明では、就寝者が眠ろうとする直前に、目覚し時計における起床時刻の設定や、照明装置の点灯状態の調整(例えば、消灯や調光)といった操作を行うことに着目した。つまり、それらの行動を行うタイミングは、上述のユーザが眠ろうとする意識を抱いたタイミングを近似しており、それを睡眠潜時の計測開始時期として検出し、睡眠潜時を計測すれば極めて正確な睡眠潜時を得ることができる。また、上記メラトニン分泌抑制低減照明への切替え時期についても、目覚し時計における起床時刻の設定や、照明装置の点灯状態の調整(例えば、消灯や調光)といった操作を行ったタイミングを基準として、その2時間前とすれば、より正確な制御が可能となる。   In order to enable the two applications described above, it is necessary to provide a means for easily and more accurately detecting the timing when the user is conscious of going to sleep. Therefore, in the present invention, attention is focused on performing operations such as setting the wake-up time in the alarm clock and adjusting the lighting state of the lighting device (for example, turning off or dimming) immediately before the sleeper tries to sleep. In other words, the timing of performing these actions approximates the timing when the above-mentioned user is conscious of going to sleep, and it is extremely accurate if it is detected as the measurement start time of sleep latency and the sleep latency is measured. A good sleep latency. In addition, the timing for switching to the above-described melatonin secretion-reducing illumination is also based on the timing of the operation such as setting the wake-up time in the alarm clock and adjusting the lighting state of the lighting device (for example, turning off or dimming). If it is two hours ago, more accurate control is possible.

このように、本発明は、就寝時にユーザが照明状態の調整や目覚まし時刻の操作を行ったタイミングを、睡眠潜時の測定開始時期として検出することで、睡眠潜時を正確に検出でき、メラトニン分泌抑制低減照明の制御が可能となり、睡眠の客観的評価と睡眠改善が図れる照明システムを提供することを目的とする。   As described above, the present invention can accurately detect the sleep latency by detecting the timing at which the user adjusts the lighting state or operates the wake-up time as the measurement start timing of the sleep latency at the time of going to bed. An object of the present invention is to provide an illumination system that can control the secretion suppression reduction illumination and can objectively evaluate sleep and improve sleep.

以下、本発明の各種実施形態に係る照明システムについて図面を参照して説明する。
(第1実施形態)
図1は、第1実施形態に係る照明システムの構成を示す。照明システム1は、照明制御を行う制御部2と、この制御部2により一般照明とメラトニン分泌抑制低減照明とを切替え制御される照明装置3と、この照明装置3の点灯・調光などをユーザ操作により指令する照明スイッチ6と、目覚し時計7と、表示部8とを備える。また、制御部2は、メラトニン分泌抑制低減照明の制御プログラム11と、前日の目覚し時計操作時間メモリ12(記憶部)とを備える。
Hereinafter, illumination systems according to various embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 shows a configuration of an illumination system according to the first embodiment. The illumination system 1 includes a control unit 2 that performs illumination control, an illumination device 3 that is controlled by the control unit 2 to switch between general illumination and melatonin secretion suppression reduction illumination, and lighting / dimming of the illumination device 3. The lighting switch 6 commanded by operation, an alarm clock 7 and a display unit 8 are provided. Moreover, the control part 2 is provided with the control program 11 of the melatonin secretion suppression reduction illumination, and the alarm clock operation time memory 12 (memory | storage part) of the previous day.

照明スイッチ6と目覚し時計7は、就寝者の就寝意思により操作される機器であって、就寝者が、眠ろうとする直前(就寝意思生起時)に、照明スイッチ6により照明装置3の点灯状態を調節し(消灯や減光など)、叉は、目覚し時計7の目覚し時刻設定を行うことで、その時刻をユーザの就寝時刻として制御部2はメモリ12に記憶し、翌日以降の一般照明からメラトニン分泌抑制低減照明への切替え時刻を、その時刻の、例えば約2時間前に設定する。ここに、制御部2は、照明装置制御部としての機能のほか、就寝者による照明スイッチ6や目覚し時計7の操作時刻(操作タイミング情報)から就寝者が眠ろうとする意識を抱いた時期、すなわち、就寝意思生起時から入眠に至る睡眠潜時の測定開始時期を検出する睡眠潜時検出部としての機能を持つ。   The lighting switch 6 and the alarm clock 7 are devices that are operated according to the sleep intention of the sleeper. The light switch 6 turns on the lighting device 3 immediately before the sleeper tries to sleep (when the sleep intention occurs). By adjusting (turning off, dimming, etc.) or setting the alarm time of the alarm clock 7, the control unit 2 stores the time in the memory 12 as the user's bedtime, and the melatonin from the general illumination on the following day The time for switching to the secretion suppression reducing illumination is set, for example, about 2 hours before that time. Here, in addition to the function as the lighting device control unit, the control unit 2 is a time when the sleeper is conscious of going to sleep from the operation time (operation timing information) of the lighting switch 6 and the alarm clock 7 by the sleeper, that is, In addition, it has a function as a sleep latency detection unit that detects the measurement start time of the sleep latency from sleep occurrence to sleep onset.

図2及び図3は、第1実施形態に係る照明システムにおける動作のタイムチャート及びフローチャートを示す。ここでは一般的な生活リズムを想定したときを示し、図2に示すように、時系列に、ユーザの入床時刻t1、目覚し時計7の操作叉は照明スイッチ6の消灯・調光操作時刻t2、入眠(睡眠)時刻t3としたとき、時刻t2が睡眠潜時の測定開始時期であり、その時期よりも約2時間前の時刻t0あたりから、メラトニン分泌量が増大し始めるので、この時点から、制御部2は、照明装置2を通常照明からメラトニン分泌抑制低減照明に切替える。メラトニンというホルモンは、睡眠を促進するとされており、睡眠の良し悪しは、このメラトニンの分泌量が影響していると考えられている。そこで、照明制御は、メラトニン分泌が促進されるようにする。   2 and 3 show a time chart and a flowchart of the operation in the illumination system according to the first embodiment. Here, it is assumed that a general life rhythm is assumed. As shown in FIG. 2, the user's entry time t1, the operation of the alarm clock 7, or the turn-off / dimming operation time t2 of the lighting switch 6 are shown in time series. When the sleep (sleep) time t3 is set, the time t2 is the measurement start time of the sleep latency, and the melatonin secretion starts to increase from about time t0 about 2 hours before that time. The control unit 2 switches the illumination device 2 from normal illumination to melatonin secretion suppression reduced illumination. The hormone melatonin is said to promote sleep, and it is thought that the amount of melatonin secretion affects the quality of sleep. Therefore, the lighting control promotes melatonin secretion.

制御部2は、図3に示すように、現在時刻がメラトニン分泌抑制低減照明時間かを調べて(#1)、NOであれば、目覚し時計7叉は照明スイッチ6が操作されたかを調べ(#2)、これがYESなら、その操作時刻(t2)をメモリ12に記憶し(#3)、メラトニン分泌抑制低減照明とする(#4)。#1で、YESのときも、#4の動作とする。メモリ12に操作時刻(t2)が記憶されていることで、睡眠潜時の測定開始時期の前からこのような照明制御が可能となる。本実施形態の照明システム1においては、このような動作により、就寝者の生活リズムに応じて、検出された睡眠潜時の測定開始時期に基づいて、同時期前に一般照明からメラトニン分泌抑制低減照明へ自動的に切替えることが可能となり、ユーザは面倒な手動切替えから解放される。なお、本第1実施形態では前日の目覚まし時計操作時間をメモリすることとしたが、メモリの内容については、前の週全体にわたる操作時間の平均値としたり、三交代勤務のように起床時間帯がシフトする場合に勤務日程を考慮したものとするように、就寝者の生活様式を考慮した任意のものを設定することができる。   As shown in FIG. 3, the control unit 2 checks whether the current time is the lighting time for melatonin secretion suppression reduction (# 1), and if NO, checks whether the alarm clock 7 or the lighting switch 6 is operated ( # 2) If this is YES, the operation time (t2) is stored in the memory 12 (# 3), and the melatonin secretion suppression reduced illumination is set (# 4). When # 1 is YES, the operation is # 4. Since the operation time (t2) is stored in the memory 12, such illumination control can be performed before the measurement start time of the sleep latency. In the lighting system 1 of the present embodiment, by such an operation, the melatonin secretion suppression reduction from the general lighting before the same period based on the measurement start time of the sleep latency detected according to the life rhythm of the sleeping person. It is possible to automatically switch to lighting, freeing the user from cumbersome manual switching. In the first embodiment, the alarm clock operation time of the previous day is stored in memory. However, the contents of the memory are the average value of the operation time over the previous week or the wake-up time zone as in the three shift work. Anything that takes into account the sleeper's lifestyle can be set so that the work schedule is taken into account when the shift occurs.

(第2実施形態)
図4は、第2実施形態に係る照明システムの構成を示す。この照明システム1は、就寝者が入眠したことを検出する睡眠検出部として、ユーザの体移動量を検出する、就寝ベッドに配置された圧電素子センサ4叉は赤外線センサ5から成る体動量検知センサを備えている。睡眠検出部は、体動量がある一定量まで減少した時点で入眠とする。赤外線センサ5は、照明装置3と一体型若しくは個別でもよい。睡眠検出部としては、脳波、心拍、血圧データなどを検出して入眠したと判定するようにしてもよい。
(Second Embodiment)
FIG. 4 shows a configuration of an illumination system according to the second embodiment. This lighting system 1 is a body movement amount detection sensor comprising a piezoelectric element sensor 4 or an infrared sensor 5 disposed on a sleeping bed, which detects a user's body movement amount as a sleep detection unit that detects that a sleeper has fallen asleep. It has. The sleep detection unit is set to fall asleep when the amount of body movement decreases to a certain amount. The infrared sensor 5 may be integrated with the lighting device 3 or may be individual. The sleep detection unit may be determined to have fallen asleep by detecting brain waves, heartbeats, blood pressure data, and the like.

制御部2は、就寝意思生起時から入眠までの睡眠潜時を算出するプログラム13(睡眠潜時検出部)を備え、この睡眠潜時から、就寝者の睡眠評価を行う機能をも持つ(睡眠評価手段)。また、制御部2は、照明スイッチ6叉は目覚し時計7の操作時刻からユーザが眠ろうとする意識を抱いた時期(就寝意思生起時)を検出し、さらに、圧電素子センサ4叉は赤外線センサ5による体動の減少を検出し、それらの検出結果から睡眠潜時を算出し、その結果を表示部8にてユーザへ提示し、また、照明装置3を制御する。なお、図示を省いているが、第2実施形態の照明システムは、第1実施形態と同等の構成を備えているが、以下では、第2実施形態特有の作用についてのみ説明する。   The control unit 2 includes a program 13 (sleep latency detection unit) that calculates a sleep latency from the time when the willingness to sleep until sleep onset occurs, and also has a function of performing sleep evaluation of the sleeper from this sleep latency (sleep). Evaluation means). In addition, the control unit 2 detects a time when the user is conscious of going to sleep (at the time of going to sleep) from the operation time of the lighting switch 6 or the alarm clock 7, and further, the piezoelectric element sensor 4 or the infrared sensor 5 The decrease in body movement due to the above is detected, the sleep latency is calculated from the detection results, the result is presented to the user on the display unit 8, and the lighting device 3 is controlled. Although not shown, the illumination system of the second embodiment has the same configuration as that of the first embodiment, but only the operation unique to the second embodiment will be described below.

図5及び図6は、第2実施形態に係る照明システムにおける動作のタイムチャート及びフローチャートを示す。図5に示すように、ユーザが入床t1の後、眠ろうとする直前に、照明スイッチ6により照明装置3の点灯状態を調節し(消灯や減光など)、叉は、目覚し時計7の目覚まし時刻設定を行う(t2)。その時刻をユーザの就寝時刻として制御部2は記憶し、次に、圧電素子センサ4叉は赤外線センサ5で成る睡眠検出部により検出した体動量の減少や、脳波、心拍、血圧データなどから判定された睡眠時期(入眠:t3)と前記就寝時刻(t2)との比較により、睡眠潜時を算出する。この睡眠潜時を表示部8に表示すれば、ユーザは自分の入眠状態の良し悪しを把握することができ、毎日の健康管理に役立てることができる。   5 and 6 show a time chart and a flowchart of the operation in the illumination system according to the second embodiment. As shown in FIG. 5, the lighting switch 6 adjusts the lighting state of the lighting device 3 (lights off, dimming, etc.) immediately after the user enters the bed t1 and immediately before going to sleep, or the alarm clock 7 wakes up. Time setting is performed (t2). The control unit 2 stores the time as the bedtime of the user, and then makes a determination based on a decrease in body movement detected by the sleep detection unit including the piezoelectric element sensor 4 or the infrared sensor 5, brain wave, heart rate, blood pressure data, and the like. The sleep latency is calculated by comparing the sleeping time (sleeping time: t3) and the sleeping time (t2). If this sleep latency is displayed on the display unit 8, the user can grasp whether his / her sleep state is good or bad and can be used for daily health management.

また、入眠状況に応じて照明を調整すればよい。夜間にメラトニンが多く分泌されれば入眠は円滑となるので、上記の睡眠潜時の算出結果から、睡眠までに比較的時間を要している場合には、メラトニン分泌が不十分であると推測でき、上述のメラトニン分泌抑制低減照明への切替え時間を早くするなどして、分泌量が増えやすくするように対処すればよい。   Moreover, what is necessary is just to adjust illumination according to a sleep state. If a lot of melatonin is secreted at night, sleep is smooth, so from the above calculation result of sleep latency, it is estimated that melatonin secretion is insufficient when it takes a relatively long time to sleep. This can be done by making the switching time to the above-mentioned melatonin secretion suppression reduced illumination faster, etc., so as to make the secretion amount easy to increase.

制御部2は、図6に示すように、目覚し時計7叉は照明スイッチ6が操作されると(#11でYES)、体動量を検知し(#12)、体動量が一定値以下になれば(#13でYES)、睡眠潜時を算出し(#14)、睡眠潜時より睡眠評価し、それを表示し(#15)、照明装置が調光されるように設定された場合に、照明装置を調光する(#16)。なお、図6においては、エンドからスタートに戻るループを設定することも当然にできる。本実施形態の照明システム1においては、このような動作により、体動量検出だけでの睡眠潜時検出に比べて、簡易な構成でもって正確な睡眠潜時検出が可能となり、また、それに基づいた就寝者の睡眠評価が可能となり、ユーザの健康管理に役立てることができる。   As shown in FIG. 6, when the alarm clock 7 or the illumination switch 6 is operated (YES in # 11), the control unit 2 detects the amount of body movement (# 12), and the amount of body movement becomes less than a certain value. If the sleep latency is calculated (# 14), the sleep is evaluated from the sleep latency, the sleep evaluation is displayed (# 15), and the lighting device is set to be dimmed The lighting device is dimmed (# 16). In FIG. 6, it is naturally possible to set a loop that returns from the end to the start. In the illumination system 1 of the present embodiment, such an operation enables accurate sleep latency detection with a simple configuration as compared to sleep latency detection based only on body movement amount detection. Sleep evaluation of a sleeping person is attained, and it can be used for a user's health management.

なお、本発明は、上記実施例の構成に限られることなく、発明の趣旨を変更しない範囲で種々の変形が可能である。照明スイッチ6と目覚し時計7は、兼用した形態でもよい。   The present invention is not limited to the configuration of the above embodiment, and various modifications can be made without departing from the spirit of the invention. The illumination switch 6 and the alarm clock 7 may be combined.
