Description

  The present invention relates to a bedroom lighting system that can wake up comfortably even when a plurality of sleeping beds are arranged side by side, even when the bedtime is different.

  Conventionally, awakening by controlling lighting is important for providing a comfortable awakening because the sleep rhythm and the wake-up rhythm can be matched. A system that wakes up by illumination control is proposed in Japanese Patent Application Laid-Open No. 07-318670 (Patent Document 1) and Japanese Utility Model Application Laid-Open No. 06-078895 (Patent Document 2).

  By the way, there is a high possibility that the timing of getting up is different when sleeping in the same room. However, the problem with conventional lighting control is that two people wake up simultaneously.

JP 07-318670 A Japanese Utility Model Publication No. 06-078895

  However, in a residential environment where multiple people live, the bedroom is often used by multiple people. However, the technique of Patent Document 2 induces comfortable awakening at each individual wake-up time in the same room. There is a problem that cannot be done.

  The present invention solves the above-mentioned problems, and an object of the present invention is to provide a bedroom lighting system that can be awakened comfortably by lighting control when sleeping in the same room, and can shift the wake-up timing. It is something to be done.

  In order to achieve the above object, a first configuration of a bedroom lighting system according to the present invention is provided between an awakening preparation lighting group provided on each headboard of a plurality of sleeping beds arranged side by side and the sleeping bed provided next to each other. A night table that shields light from awakening preparation lighting group from other sleeping beds provided on the headboard, and provided on both sides of the night table to wake up and wake up completely A wake-up illumination group for resetting the biological rhythm, and control means for controlling the wake-up preparation illumination group and the wake-up illumination group.

  Moreover, the 2nd structure of the bedroom lighting system which concerns on this invention is a body temperature measuring means which measures the body temperature of the person sleeping in the said bed in the said 1st structure, and the body temperature measured by the said body temperature measuring means. A sleep curve creating unit that creates a sleep curve based on the sleep curve created by the sleep curve creating unit, and the control unit generates the illumination group for awakening preparation at the time of transition from REM sleep to non-REM sleep in the sleep curve created by the sleep curve creating unit. It is set to ON.

  Further, a third configuration of the bedroom lighting system according to the present invention is characterized in that, in the first configuration, the bedroom lighting system includes body temperature raising means that is controlled by the control means in accordance with the timing of awakening and promotes an increase in body temperature. To do.

  Moreover, the 4th structure of the bedroom lighting system which concerns on this invention is a body temperature measurement sheet | seat laid in the said bed in the said 2nd structure, The said body temperature measurement means is characterized by the above-mentioned.

  According to the first configuration of the bedroom lighting system according to the present invention, the light from the wake-up preparation lighting group provided on the headboard of another adjacent sleeping bed can be shielded by the night table, and the wake-up time However, it is not affected by other wake-up preparation lighting groups that are different from each other, and does not suffer from sleep disturbance.

  Also, in response to a preset wake-up time, as a wake-up preparation stage, the control means turns on the wake-up preparation lighting group at the time of transition from REM sleep to non-REM sleep and responds to a predetermined time-illuminance curve. By gradually increasing the illuminance of the wake-up preparation illumination group and turning on the wake-up illumination at a predetermined timing before the wake-up time, the user can wake up comfortably.

  Here, REM sleep and non-REM sleep will be described. When sleep gradually becomes deep after falling asleep, REM (Rapid eye movement; REM) sleep appears next. The characteristics of REM sleep are similar to the stage of non-REM sleep on the electroencephalogram, but rapid eye movements are observed, and many people dream about such sleep periods. REM sleep is qualitatively different from non-REM sleep in various physiological phenomena and depth of sleep. Such REM sleep and non-REM sleep appear as 5 to 6 times until they wake up in the morning by repeating them alternately in an overnight sleep. In healthy adults, the length of one set of REM-NREM sleep is about 90 minutes.

  As features of REM sleep, (1) rapid eye movement appears. (2) The electroencephalogram shows a pattern resembling from sleep onset to light sleep. (3) There is almost no tension in the muscles that maintain the body posture (anti-gravity muscles, posture muscles). (4) It is difficult to wake up even if sensory stimulation is given. (5) Autonomic nerve functions such as pulse, respiration and blood pressure change irregularly. (6) When waking up a person who is asleep during REM sleep, more than 80% of people have a dream.

  On the other hand, the features of non-REM sleep are as follows: (1) Eye movements that sway slowly in the shallow sleep phase of sleep onset, but after that, when the sleep becomes deeper, the eye movement stops. (2) EEG activity decreases and the frequency slows down. (3) Body muscle tension is maintained. (4) Stable pulse, blood pressure and breathing. (5) If you wake up a person who is asleep during non-REM sleep, you will not be awake and rarely dream.

  Next, the awakening preparation illumination group will be described. While one day on the earth is 24 hours, the unit of one day that humans originally have is 25 hours. It is necessary to reset the biological rhythm to synchronize the cycle of the day by 1 hour in this 25 hours and to match the cycle of the day in 24 hours. It is known that it can be accelerated by one hour. The wake-up preparation illumination group according to the present invention replaces sunlight as a reset button of the biological clock. Since natural sunlight gradually increases its illuminance from sunrise and wakes it up, the control means gradually increases the illuminance of the wake-up preparation lighting group, and finally the high illuminance with the wake-up light It is intended to wake up by illuminating with.

  Moreover, according to the 2nd structure of the bedroom lighting system which concerns on this invention, a sleep curve can be created by a sleep curve creation means based on the body temperature during sleep measured by the body temperature measurement means. Since the body temperature during REM sleep that appears alternately and repeatedly in the overnight sleep rises and the body temperature during non-REM sleep falls, the body temperature curve during sleep matches the sleep curve.

  Then, in the sleep curve created by the sleep curve creating means, the control means turns on the wake-up preparation illumination group at the time when an inflection point appears that shifts from REM sleep where the body temperature rises to non-REM sleep where the body temperature falls. Comfortable awakening can be promoted.

  In addition, according to the third configuration of the bedroom lighting system according to the present invention, the body temperature that has been lowered during sleep rises by urging the body temperature to rise in accordance with the timing of awakening by means of body temperature raising means such as an electric fan. Can wake up comfortably.

  Moreover, according to the 4th structure of the bedroom lighting system which concerns on this invention, by measuring the body temperature during sleep with the body temperature measurement sheet | seat laid on the bed, body temperature can be reliably ensured irrespective of a sleep phase and without being conscious. It can be measured and sleep is maintained.
