Hereinafter, embodiments of the present invention will be described. The embodiments described below do not unduly limit the contents of the present invention described in the claims. In addition, all of the configurations described in the following embodiments are not necessarily essential components of the invention.

[1] First Embodiment [1.1] Overview First, a first embodiment of a biological rhythm adjustment device or a biological rhythm adjustment system according to the present application will be described with reference to FIG. 1 or FIG. FIG. 1 is a diagram showing the appearance of the biological rhythm adjusting device 1 of the present embodiment, and FIG. 2 is a block diagram showing the configuration of the biological rhythm adjusting device of the present embodiment.

The biological rhythm adjustment device 1 of the present embodiment irradiates the user's eyes with light within a predetermined wavelength range, forcibly adjusts the circadian rhythm of the user having an abnormality due to the living environment, etc. It is a device that adjusts the biological rhythm of the user, for example, by controlling the time zone of sleeping and the time zone of awakening according to the time.

In particular, the biological rhythm adjustment device 1 of the present embodiment
(1) At least a first light source that irradiates a first special light in a first wavelength range of 360 nm or more and 400 nm or less to a user's eye,
(2) acquiring condition data indicating conditions for irradiating the user's eyes with the first special light,
(3) controlling the irradiation of the first special light according to the acquired condition data;
It has a configuration.

Generally, “circadian rhythm” (also called circadian rhythm or biological clock) refers to a physiological phenomenon that fluctuates in a cycle of about 24 hours. When an abnormality occurs in the circadian rhythm, appetite, drowsiness, sleep, etc. Because of this, stress builds up and causes illness.

Therefore, it is necessary to stabilize the circadian rhythm by maintaining the circadian rhythm by being exposed to sunlight mainly during the daytime (during sunrise to sunset).

In addition, the human eye has cone cells and rod cells as visual cells, and performs not only visual perception but also non-visual work. For example, melanopsin-containing retinal ganglion cells (mRGC: melanopsin containing retinal ganglion cells) are known to act most strongly with light having a wavelength in the range of 460 nm ± 20 nm and affect circadian rhythm.

For example, recently, in order to improve this kind of sleep disorder, it is a therapeutic method that focuses on the relationship between melatonin secretion and light, and artificially emits strong light (5000 lux to 10000 lux) containing BL such as white light. By irradiating the patient to the patient, a treatment method (also called phototherapy or light therapy) that controls the timing of melatonin secretion and corrects the difference between the external environment and the sleep phase has also been proposed and implemented, and has been used for the treatment of late sleep phase syndrome. It is also effective against circadian rhythm sleep disorders and winter depression.

Specifically, when the mRGC receives light including 460 nm (hereinafter, also referred to as “blue light” or “BL”) within the wavelength range of 460 nm ± 20 nm, the brain ascends the chiasm that controls the biological clock. The nucleus transmits signals to the pineal gland via the superior cervical sympathetic ganglion.

Therefore, it is widely known that the suppression of melatonin secretion in the pineal gland results in an arousal state, which resets the circadian rhythm.

As a result, when sunlight is taken during the daytime (particularly, from morning to morning) and BL is received by the mRGC, the circadian rhythm is reset to a normal state (for example, 6:00). Circadian rhythm that awakens between 8:00 and 8:00 and is drowsy between 21:00 and 24:00, which is not a hindrance to normal social life.

In addition, as light for adjusting the circadian rhythm, not only BL but also light including 380 nm wavelength light within a wavelength range of 360 nm or more and 400 nm or less (hereinafter, referred to as “violet light” or “VL”) is irradiated. It has been found by experiments that the phase of the circadian rhythm also shifts in the same manner and the circadian rhythm can be reset and adjusted.

In particular, the present inventor, unlike the case of BL, irradiates VL including 380 nm wavelength light within the wavelength range of 360 nm or more and 400 nm or less, similarly to the case of irradiating BL, the phase of the circadian rhythm is changed. It shifted and confirmed that reset and adjustment of the circadian rhythm were possible.

実 験 In this experiment, the mice were irradiated with VL for a short period of time, so that the mice were irradiated with a small amount of energy VL and the change in the activity was monitored. FIG. 4 shows the change in the amount of mouse activity observed in the experiment.

分 か る As will be described later, it can be seen that the amount of activity of the mouse changes by irradiating VL, and the phase of the circadian rhythm is shifted. Further, from the experimental results, it was found that even if the amount of VL energy applied to the subject was low, it was effective in resetting and adjusting the circadian rhythm.

In addition to the above, the present inventors also investigated the effects on the human body when VL irradiation was performed.

Specifically, in the survey, the eye of the subject was irradiated with 310 μW / cm ² VL for 2 hours during the daytime, and the turnover frequency and movement of the subject during sleep on the irradiation day were measured. By detecting with a sensor, the cycles of REM sleep and non-REM sleep were monitored, and the effect of VL irradiation on the sleep quality of the subject was investigated.

Under the same conditions, a survey of a plurality of subjects was repeated daily for about six months, and the quality of sleep was improved in all subjects, and the next morning awakening was performed. Turned out to be better.

This indicates that the VL irradiation has the effect of adjusting the disturbance of the circadian rhythm of humans.

The mechanism by which VL influences circadian rhythm may be due to mRGC, as in BL, but mRGC has a sensitivity peak at 460 nm and is not highly sensitive in the VL wavelength region. . Therefore, it is presumed that retinal cells other than mRGC are likely to contribute to the circadian rhythm adjustment function of VL.

On the other hand, in the modern society, information communication terminal devices such as smartphones have become dramatically widespread, and we look at smartphones, game consoles, personal computers, or display devices such as televisions face-to-face regardless of day or night. Have a good lifestyle.

Since light emitted from this type of display device includes light in the wavelength band of BL, if this type of display device is used late in the night, even when it is time to sleep, the pineal body Melatonin secretion is suppressed.

Therefore, such lifestyle habits disrupt circadian rhythm and cause sleep disorders (circadian rhythm sleep disorders) caused by circadian rhythm such as delayed sleep phase syndrome.

Therefore, the biological rhythm adjustment device 1 of the present embodiment corrects the disturbance of the circadian rhythm of the user by utilizing the influence of the VL and BL on the circadian rhythm, and adjusts the sleep time and the awake time according to the living environment. Is controlled, and as a result, the physical and mental health of the user can be maintained and promoted.

Particularly, in order to reset or adjust the circadian rhythm of the user, it is ideal that the user actually takes the sunlight outdoors. Are irradiated with VL and BL to the user's eyes according to the ratio of VL and BL included in the image, and have a configuration of irradiating the user's eyes while reproducing light similar to sunlight.

Specifically, as shown in FIG. 1, the biological rhythm adjustment device 1 of the present embodiment is configured as a glasses-type wearable device that is worn close to the user's eyes. A light source 11 for the right eye and a light source 12 for the left eye are provided at positions facing the left and right eyes of the user when worn on the face.

Each of the light sources 11 and 12 is provided, for example, at the center of a portion where the lens is fixed in the spectacle frame, and has VL irradiation LEDs (light emitting diodes) 11V and 12V, respectively, and BL irradiation LEDs 11B and 11B. 12B.

The light sources 11 and 12 have a configuration in which the biological rhythm adjustment device 1 is attached to the user's face and irradiates the user's eyes with VL and BL with the user's eyes open.

Note that, in the biological rhythm adjustment device 1 of the present embodiment, as the light sources 11 and 12, a light source in which LEDs 11V and 12V for VL irradiation and LEDs 11B and 12B for BL irradiation are combined is used. However, a hybrid LED that can selectively emit VL and BL with one LED may be used.

Further, since both the VL and the BL have the ability to adjust the circadian rhythm as described above, even when only the BL or only the VL is irradiated to the user's eyes, it is possible to correct the disturbance of the circadian rhythm of the user. It is possible.

However, in the present embodiment, a description will be given assuming that a configuration for simultaneously irradiating VL and BL to the user's eye is employed in order to enhance the circadian rhythm adjustment function.

[1.2] Configuration of Biological Rhythm Adjusting Device Next, the configuration of functional blocks of the biological rhythm adjusting device 1 of the present embodiment will be described with reference to FIG. FIG. 2 is a block diagram illustrating a configuration of functional blocks of the biological rhythm adjustment device 1 of the present embodiment.

As shown in FIG. 2, the biological rhythm adjustment device 1 of the present embodiment includes a light source 11 for the right eye, a light source 12 for the left eye, and a right light source for driving the LEDs 11B and 11V built in the light source 11 for the right eye. An eye light source drive circuit 110 and a left eye light source drive circuit 120 for driving the LEDs 12B and 12V incorporated in the left eye light source 12 are provided.

The biological rhythm adjustment device 1 includes an operation unit 130 for the user to perform various input operations, a ROM / RAM 140, and a CPU (central processing unit) 150. The above-described units are mutually connected by a bus, and exchange various data and signals.

The light source 11 for the right eye and the light source 12 for the left eye include LEDs 11B and 12B for BL irradiation and LEDs 11V and 12V for VL irradiation, respectively.

The right-eye light source drive circuit 110 and the left-eye light source drive circuit 120 supply drive signals to the LEDs 11B, 11V, 12B, and 12V built in the corresponding light sources 11 or 12, respectively, under the control of the CPU 150. , LEDs 11B, 11V, 12B, and 12V emit light. The light source driving circuit 110 for the right eye and the light source driving circuit 120 for the left eye of the present embodiment cooperate with the light sources 11 and 12 to constitute, for example, an “irradiating unit” of the present invention.

In particular, the right-eye light source drive circuit 110 and the left-eye light source drive circuit 120 change the drive signals supplied to the LEDs 11B, 11V, 12B, 12V according to the control signals supplied from the CPU 150, and change the LEDs 11B, 11V, 12B, It has a function of adjusting the illuminance of VL and BL irradiated from 12V.

The method of adjusting the illuminance of VL and BL emitted from the LEDs 11B, 11V, 12B, and 12V by the right-eye light source driving circuit 110 and the left-eye light source driving circuit 120 is arbitrary. For example, the light source driving circuit 110 for the right eye and the light source driving circuit 120 for the left eye may change the driving signal supplied to the light sources 11 and 12 by a PWM (pulse wide modulation) method to adjust the illuminance. .

(4) The right-eye light source drive circuit 110 and the left-eye light source drive circuit 120 emit VL and BL from the LEDs 11V, 11B, 12V, and 12B with illuminance according to the control signal supplied from the CPU 150.

The operation unit 130 includes, for example, various buttons such as a power button, a cross-shaped operation button, and an enter button, and outputs an operation command corresponding to an input operation performed by the user to the CPU 150 via the bus.

Various buttons of the operation unit 130 are provided on the housing of the biological rhythm adjustment device 1 and can be operated by the user even when the biological rhythm adjustment device 1 is worn by the user. Position.

The ROM / RAM 140 has a nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read Only Memory) and a RAM (Random Access Memory) used as a work area.

The ROM / RAM 140 stores a control program for the biological rhythm adjustment device 1 and control data for controlling light emission of the light sources 11 and 12.

In particular, in the present embodiment, the ROM / RAM 140 stores condition data that defines the irradiance when irradiating VL and BL to the user's eyes.

For example, the ROM / RAM 140, in association with the modes (1) first mode: the irradiance irradiance 100μW / ^cm 2, VL of BL 50 W / ^cm 2,
(2) Second mode: BL irradiance is 120 μW / cm ² , VL irradiance is 60 μW / cm ² ,
(3) Third mode: BL irradiance is 140 μW / cm ² , VL irradiance is 70 μW / cm ² ,
For example, control data for irradiating VL and BL from the light sources 11 and 12 at the irradiance corresponding to each mode is stored.

The CPU 150 controls the light source driving circuit 110 for the right eye and the light source driving circuit 120 for the left eye so that VL and BL are irradiated to the user's eyes at the irradiance specified by the condition data.

In particular, the CPU 150 executes a process for irradiating the user's eyes with VL and BL at the irradiance indicated by the condition data according to the program stored in the ROM / RAM 140.

Further, the CPU 150 executes control for allowing the user to set the irradiation period and the irradiation mode as described above as condition data when the user's eyes are irradiated with VL and BL. The light source driving circuit 110 for the right eye and the light source driving circuit 120 for the left eye are controlled so that the user's eyes are irradiated with VL and BL at the ratio included in the above.

For example, the CPU 150 reads out one control data selected automatically from a control data stored in the ROM / RAM 140 by a timer (not shown) or by operating the operation unit 130.

Then, the CPU 150 uses the control data corresponding to the read mode to irradiate the user's eyes with VL and BL at the irradiance corresponding to the selected mode, and uses the right-eye light source drive circuit 110 and the left The eye light source drive circuit 120 is controlled.

The user can freely select not only the irradiation period but also the irradiance so that the circadian rhythm can be adjusted by irradiating VL and BL to the user's eyes while adjusting to the user's physical condition. I have.

{Circle around (5)} In conjunction with the operation unit 130, the CPU 150 allows the user to set the irradiation period according to a predetermined procedure. For example, in the setting mode, the CPU 150 increases the irradiation period for a predetermined time (for example, 5 minutes or 10 minutes) each time the upward direction of the cross key of the operation unit 130 is pressed once, and each time the downward direction is pressed. The irradiation period may be reduced by the time, and after selecting the period, the irradiation period may be set by pressing the enter key.

Further, in the present embodiment, the irradiance of VL and BL applied to the user's eyes needs to be the irradiance of VL and BL on the surface of the user's eyes. Since the light sources 11 and 12 are arranged close to the eyes of the user, there is almost no need to consider light attenuation due to the distance, so that this function can be realized without using a high-power LED.

[1.3] Animal Experiment on Effect of VL on Circadian Rhythm Next, the result of an animal experiment on the effect of VL on circadian rhythm in the present embodiment will be described with reference to FIGS.

FIG. 3 is a diagram showing experimental conditions of an animal experiment showing a change in the activity of a mouse in accordance with a change in the energy of VL given in a pulsed manner. FIG. 4 shows an animal experiment using the mouse. FIG. 9 is a diagram showing an actogram showing the measurement result of the activity amount of the mouse belonging to group A and an actogram showing the measurement result of the activity amount of the mouse belonging to group B. FIG. 5 is a graph showing the phase shift amount of circadian rhythm obtained by an animal experiment using a mouse.

(1) Experimental conditions First, experimental conditions will be described with reference to FIG.

In this experiment, 6-week-old male mice were divided into two groups (groups A and B), and each group was irradiated with light under the following conditions.

(A) Group A
The mice belonging to this group were irradiated with light having a spectrum as shown in FIG. 3A (hereinafter, referred to as “white light” or “WL”) using a normal white LED. Many white LEDs are modules that generate white by combining a blue LED as a light emitting body and a yellow phosphor, and FIG. 3A shows an emission spectrum of such a white LED.

At this time, as shown in FIG. 3C, between 8:00 and 20:00 (that is, 12 hours), the LED of the WL is turned on, and it becomes 100 to 300 lux at the bottom of the mouse cage. The mice were exposed to WL as described above, the LEDs were turned off at 20:00, and the situation was darkened for 12 hours (hereinafter referred to as “bright and dark situation”) for one week. Thereafter, 10 lux WL was continuously irradiated for 30 minutes in a dark state, and the amount of activity was measured (hereinafter, referred to as “constant dark condition”).

(B) Group B
The mice belonging to this group were irradiated with VL together with WL, and were irradiated with light having a spectrum as shown in FIG.

At this time, as shown in FIG. 3 (C), the mice belonging to group B were exposed to light containing both WL and VL under the light / dark condition for one week, similarly to the mice belonging to group A. After repeating the irradiation, 10 lux light including both WL and VL was continuously irradiated for 30 minutes under a constant dark condition, and the activity was measured.

(2) About experimental results The running wheel was used for the activity measurement in this experiment. Specifically, the mouse irradiated with light under the above conditions was put into a running wheel, and the amount of movement of the mouse was calculated based on the amount of rotation of the running wheel.

結果 As a result, the measurement results of the amount of activity as shown in FIG. 4A were obtained for the mice belonging to group A, and as shown in FIG. 4B for the mice belonging to group B.

4 (A) and 4 (B), the vertical axis indicates the amount of mouse activity every 30 minutes, and the horizontal axis indicates time. Each row has a time length of 48 hours, and the last 24 hours of each row and the first 24 hours of the next row are overlapped.

(4) Although the lines shown in FIGS. 4A and 4B are originally continuous, discontinuities are recognized as shown in FIGS. 4A and 4B.

The discontinuous portion (ie, the portion indicated by the arrow in FIGS. 4A and 4B) indicates the phase shift amount of the circadian rhythm.

グ ラ フ When the phase shift amount of the circadian rhythm thus obtained was graphed, the result as shown in FIG. 5 was obtained. The P value in the measurement result of the phase shift amount shown in FIG. 5 is 0.005. In FIG. 5, the vertical axis represents time (minute).

(5) As shown in FIG. 5, the amount of phase shift in group B was larger than that in group A. This means that by irradiating VL together with WL than in the case of irradiating only WL, the amount of phase shift is increased.

From the above experimental results, it has been newly found that the circadian rhythm can be adjusted by irradiating the living body with VL to change the phase of the circadian rhythm.

[1.4] Ratio of VL and BL Irradiated to User's Eye Next, the ratio of VL and BL irradiated to the user's eye by the biological rhythm adjustment device 1 in this embodiment will be described with reference to FIG.

FIG. 6 is a diagram showing the international standard data “AM1.5G” of sunlight with the horizontal axis representing the wavelength and the vertical axis representing the spectral irradiance, and the ratio of the spectral irradiance spectrum and the spectral irradiance in the international standard data. FIG. 3 is a diagram illustrating irradiance per unit wavelength of BL and VL included in sunlight.

Spectral irradiance of the VL and BL contained in sunlight, as shown in FIG. 6 (A), VL is about 70μW ^/ cm 2 ^/ nm, BL becomes approximately 153μW / ^cm 2 / nm. Therefore, the ratio between VL and BL contained in sunlight is VL: BL = 1: 2.2 with reference to spectral irradiance.

On the other hand, as shown in FIG. 6 (B), the irradiance per unit wavelength of the VL and BL contained in sunlight, VL is about 70.05μW ^/ cm 2 ^/ nm, BL is 128.875μW / cm ² / Nm. Therefore, the ratio between VL and BL contained in sunlight is VL: BL = 1: 1.8, based on the spectral irradiance per unit wavelength.

In the definition of the wavelength ranges of VL and BL, the width of the wavelength range of VL is 40 nm (= 400-360), while the width of the wavelength range of BL is 120 nm (= 500-380). Are different.

For this reason, since it is not appropriate to compare the irradiances of BL and VL (15465 μW / cm ² and 2802 μW / cm ² ), the irradiance per unit wavelength is divided by the width of the wavelength range (120 nm and 40 nm). Is calculated, and the comparison is performed using the calculated values.

That is, the irradiance of 128.875 μW / cm ² per unit wavelength of BL is 15465 μW / cm ² @ 120 nm, and the irradiance of 70.05 μW / cm ² per unit wavelength of VL is 2808 μW / cm ² ÷ 40 nm. A value is calculated.

(4) The ratio of VL to BL contained in sunlight is approximately 1: 2 ± 0.2 both on the basis of spectral irradiance and on the basis of spectral irradiance per unit wavelength. Based on the above considerations, the biological rhythm adjustment device 1 of the present embodiment employs a configuration in which VL and BL are irradiated at a ratio of about 1: 2.

On the other hand, if the user's eyes are irradiated with too strong VL and BL, the user may feel dazzling and feel uncomfortable.

Especially, irradiating too strong BL to the user's eyes is also undesirable from the viewpoint of the safety of the user's eyes. For example, irradiating the user's eye with too strong BL may cause discomfort and may affect the retina.

On the other hand, based on the wavelength characteristics of the BL LED used in the prototype, the present inventor calculated based on safety standards according to IEC (International Electrotechnical Commission) 62471 and JIS (Japanese Industrial Standards) C7550. , BL, the safety can be surely secured if the irradiance is 160 μW / cm ² or less.

Specifically, the value of the following expression defines the risk exposure of the retina caused by small BL light source in IEC62471 (1) definitive _{E B} (effective irradiance), while using a biological rhythm adjustment device 1 equipped with the LED BL The result value of the irradiance measured under predetermined conditions was 143 μW / cm ² . At this time, the effective irradiance calculated according to (Equation 1) is 89 μW / cm ² . In a situation where the wavelength dependence of light does not change and “E _λ ” in (Equation 1) does not change, the irradiance and the effective irradiance are in a proportional relationship, and the limit value of the effective irradiance is 100 μW / cm. ² (= 1 W / m ² ), the irradiance is about 143 × 100/89 = 160 μW / cm ² , and if the irradiance is up to 160 μW / cm ² , the light is irradiated to the user's eyes. In this case, safety can be ensured.

For this reason, in the present embodiment, the irradiance of the BL irradiated to the user's eyes is set to 160 μW / cm ² , which is the upper limit value for ensuring safety, and the irradiance of the VL is reduced to half of 80 μW / cm. cm ² (thus simulating sunlight by setting the irradiance ratio of VL and BL to 1: 2), and light emission control data indicating the irradiance is used as the above condition data. A configuration is pre-stored in the ROM / RAM 140 in advance.

As described above, the biological rhythm adjustment device 1 of the present embodiment can irradiate the user's eyes with VL and BL at a rate included in sunlight during the period set by the user while ensuring safety. The circadian rhythm can be adjusted reliably.

Further, since the upper limit of the irradiance of BL at which the safety can be reliably ensured is 160 μW / cm ² as described above, the VL: BL ratio is set to about 1: 2 within a range not exceeding this. If set, the circadian rhythm adjustment function can be performed while ensuring safety, because VL and BL can be applied to the user's eyes at a ratio included in sunlight regardless of which mode is selected. It can also be improved.

The same reference numerals are used for the same members, and the description is omitted.

In particular, as shown in FIG. 7, the biological rhythm adjustment system 100 according to the present embodiment includes a wearable device 10 having light sources 11 and 12, a smartphone and a tablet-type information communication terminal connected to the wearable device 10 by wire or wirelessly. And a communication terminal device 20 such as a device.

The wearable device 10 of the present embodiment has a configuration similar to that of FIG. 2 described above, and a wired interface such as USB (Universal Serial Bus) used for communication connection with the communication terminal device 20, Bluetooth (registered trademark), IEEE (registered trademark), or the like. (Institute of Electrical and Electronics Electronics Engineers) It has an I / O interface (not shown) composed of 802.11a, g, n, ac, and the like.

In addition, the CPU 150 controls the light source driving circuit 110 for the right eye and the light source driving circuit 120 for the left eye via the I / O interface according to a control command supplied from the communication terminal device 20, and controls the VL for the user's eye. And the irradiation of BL.

The communication terminal device 20 has a function of generating a control command and transmitting it to the wearable device 10 in order to control the light emission of the light sources 11 and 12 mounted on the wearable device 10 and realize a function of adjusting the circadian rhythm of the user. Have.

Specifically, the communication terminal device 20 realizes the functions of the ROM / RAM 140 and the CPU 150 in the biological rhythm adjustment device 1 of the first embodiment.

In particular, the communication terminal device 20 stores condition data in advance, receives a user setting regarding the irradiation period while displaying a predetermined setting screen, and based on the set irradiation period and the condition data, A control command for controlling the wearable device 10 is transmitted.

Note that the wearable device 10 of this embodiment constitutes, for example, an irradiation unit of the present invention, and the communication terminal device 20 constitutes a control device of the present invention in conjunction with the CPU 150 of the wearable device 10.

Further, the communication terminal device 20 prepares a plurality of modes related to the irradiance when the VL and BL are radiated to the user's eyes in the same manner as in the first embodiment, and automatically uses a timer, In accordance with the operation, the user's eyes are irradiated with VL and BL based on the selected mode.

[3] Third Embodiment Next, a third embodiment of the biological rhythm adjustment device or the biological rhythm adjustment system according to the present invention will be described.

The present embodiment is characterized in that only the VL is irradiated to the user's eye instead of the first and second embodiments, and the other components are common. Description is omitted.

In the biological rhythm adjustment device 1 or the biological rhythm adjustment system 100 of the present embodiment, it is sufficient that the light sources 11 and 12 have at least the VL irradiation LEDs 11V and 12V, and it is not always necessary to provide the BL irradiation LEDs 11B and 12B. Does not become sex.

On the other hand, in the present embodiment, the biological rhythm adjustment device 1 or the biological rhythm adjustment system 100 has a configuration for irradiating a VL close to actual sunlight to the user's eyes.

In particular, the present inventor measured the VL irradiance actually observed outdoors in Tokyo, and obtained the following results.

(A) Sunny day: 583 μW / cm ²
(B) Day with clouds: 271 μW / cm ²

In this measurement, the VL irradiance was measured a plurality of times in each of the horizontal directions of east, west, south and north in the time zone of 10 to 16:30, and the average of the measured values in four directions was calculated. The average value in the time period was calculated.

When the annual average irradiance of the VL in Tokyo is calculated from the above measurement results and the number of sunny days (46 days) in Tokyo, it is about 310 μW / cm ² . Therefore, when the user's eye is irradiated with VL of 310 μW / cm ² , the user's eye is irradiated with the same VL as actually exposed to sunlight outdoors in Tokyo, similar to outdoors in Tokyo. The environment can be reproduced.

Therefore, the biological rhythm adjustment device 1 or the biological rhythm adjustment system 100 of the present embodiment adopts a configuration in which only the VL is irradiated to the user's eyes at an irradiance of 310 μW / cm ² .

As for VL, the amount of attenuation in the eyeball is larger and the relative luminous efficiency is lower than that of BL, so that even if the surface of the eye is irradiated with light of 310 μW / cm ² , the user may feel discomfort. Sex is low and has little effect on the retina.

Therefore, by irradiating the VL with the irradiance of 310 μW / cm ² as in the present embodiment, it is possible to irradiate the VL at the same level as that of the outdoor environment while securing the safety of the user, and to reduce the circadian rhythm. It can be adjusted reliably.

Further, in the present embodiment, only the VL is irradiated, but only the LEDs 11B and 12B for BL may be provided on the light sources 11 and 12, and only the BL may be irradiated by the same configuration.

However, when a method of irradiating only the BL or a method of simultaneously irradiating the BL and the VL is adopted, the irradiance of the BL is set to the average annual irradiance of the VL in Tokyo (310 μW / cm ² ). It is preferable to set the above upper limit to 160 μW / cm ² or less, instead of 620 μW / cm ² , which is twice the value of the above, so that the user's eyes can be protected.

I do.

In such a case, since the user cannot secure sufficient sleep time, if no countermeasures are taken, work efficiency may be reduced due to drowsiness and a mistake may be induced. Has realized a function of preventing drowsiness during business execution by awakening function described later.

On the other hand, if the user's sleep is prohibited for a predetermined period by the awakening function, the circadian rhythm of the user is disturbed, and the mind and body may be affected. This requires adjusting bedtime and synchronizing circadian rhythm with everyday life.

In particular, for example, when business shifts such as two shifts and three shifts change, adjusting the bedtime according to the change in the situation and synchronizing the circadian rhythm with the new shift will maintain and improve health. It is desirable for improving work efficiency.

And a RAM 213e to be used.

The data configuration of the irradiation history data stored in the irradiation history data storage unit 213b is arbitrary, and may be, for example, data indicating an irradiation period during which the user's eyes are irradiated with VL and BL. The data may be energy amount data defined by the illuminance. In the present embodiment, the irradiation control data storage unit 213c stores condition data necessary for irradiating VL and BL at the ratio of sunlight (that is, irradiance of BL is 160 μW / cm ² , irradiance of VL Is defined as 80 μW / cm ² ).

The display unit 214 is configured by a liquid crystal panel or an organic EL display panel.

The display control unit 215 executes various controls for displaying a predetermined image on the display unit 214 including the image for the touch panel.

The sensor unit 222 includes, for example, various sensors such as an acceleration sensor, a gyro sensor, and an illuminance sensor that detects light (various lights including sunlight and illumination light) around the user.

[4.4] Application Execution Unit Next, the configuration of the application execution unit 219 in the communication terminal device 20 of the present embodiment will be described.

(Data acquisition unit)
In order to adjust the circadian rhythm, the data acquisition unit 219a acquires the location information of the user in conjunction with the current location detection unit 220, and specifies the location of the user. Then, the data acquisition unit 219a acquires sunshine information (that is, weather data) including the sunrise date and time and the sunset date and time at the specified location as information for setting the irradiation period.

In particular, the data acquisition unit 219a acquires the sunshine information from the information management server device 30 or a weather data management server device (not shown) via the network communication unit 211.

The method of acquiring the sunshine information is arbitrary. For example, the data acquisition unit 219a transmits the location of the user to a weather information management server device provided on the network N, and transmits the transmitted location information. , The sunshine information corresponding to the location may be acquired.

(Action schedule data generation unit)
The action schedule data generation unit 219b generates action schedule data of the user based on the scheduler of the user.

In particular, the action schedule data generation unit 219b displays a screen for inputting an action schedule including a desired bedtime and a sleep prohibition period on the display unit 214, and also performs an input performed on the operation unit 217 by the screen and the user. Based on the operation, action schedule data including a sleep prohibition period and a desired bedtime is generated.

{The action schedule data generation unit 219b stores the generated action schedule data in the action schedule data storage unit 213d.

For example, the action schedule data generation unit 219b
(1) By having the user specify the start date and time and the end date and time of the sleep prohibition period, the period from the start date and time to the end date and time specified by the user is set as the sleep prohibition period, or
(2) The user is allowed to specify only the end date and time of the sleep prohibition period, and automatically set a sleep prohibition period from a time limit specified by the user to a date and time a predetermined time (for example, 24 hours),
Generate action schedule data.

Regarding the setting of the sleep prohibition period in (2) above, it is desirable that the user can freely select how many hours before the end date and time of the sleep prohibition period to set the sleep prohibition period.

That is, for example, the action schedule data generation unit 219b determines that a user engaged in two-shift or three-shift work has a work period (8 hours in the case of three shifts, By setting in advance two shifts, for example, 12 hours) and inputting only the shift end date and time, the user's own working hours are automatically set as the sleep prohibition period by a simple operation.

(Irradiation period setting section)
The irradiation period setting unit 219c sets the irradiation period of BL and VL based on the generated action schedule data. At this time, the irradiation period setting unit 219c performs the following processing to set the irradiation period according to whether or not the sleep schedule period is included in the action schedule data.

(A) When the scheduled activity data includes a sleep prohibition period In this case, the irradiation period setting unit 219c ignores the desired bedtime information included in the activity schedule data and sets the sleep prohibition period as the irradiation period. Set. In this case, VL and BL are radiated to the user's eyes at the irradiance specified by the condition data over the entire sleep prohibition period, and the awakening function is realized.

(B) When Only the Desired Sleeping Date and Time Information is Included in the Action Schedule Data In this case, the irradiation period setting unit 219c sets the irradiation start time of the VL and BL to the user's eye and the irradiation end based on the desired sleeping time and date. Set the time.

For example, the irradiation period setting unit 219c specifies a time at which the user wakes up, calculates a period from the specified wake-up time to noon (hereinafter, also referred to as a “morning period after wake-up”), and calculates the calculated after wake-up. Set the morning period as the irradiation period.

In particular, in order to maintain and adjust the circadian rhythm to a normal state, it is desirable to irradiate the user's eyes with BL and VL by shining sunlight during the time period from wake up to noon, and more preferably from wake up. It is desirable to take sunlight and absorb BL and VL in all time periods until noon.

The irradiation period setting unit 219c detects, for example, a time at which the user performs a predetermined input operation on the operation unit 217 as the time at which the user wakes up, and specifies the detected time as the wake-up time. Alternatively, the wake-up alarm may be set by the user, and the time at which the alarm is canceled may be specified as the wake-up time.

However, in the present embodiment, in order to make the description concrete, the user keeps the communication terminal device 20 on the bedside, detects vibration when the user gets up with the sensor unit 222, and wakes up the user. The description will be made assuming that the date and time are specified.

For example, when the user wakes up at 7:45 on December 1, 2017, the communication terminal device 20 calculates the morning period after getting up as 4 hours and 15 minutes, and sets the irradiation period to 4 hours and 15 minutes.

In the human body, it is widely known that the melatonin concentration in the pineal gland increases about 13 to 15 hours after sun exposure after waking up, causing drowsiness. The irradiation period setting unit 219c of the embodiment may set the time 14 hours before the desired bedtime set by the user as the irradiation start time so as to cause drowsiness at the desired bedtime.

For example, when 24:00 on December 1, 2017 is set as the desired bedtime, the irradiation period setting unit 219c sets the irradiation start date and time 10:00 on December 1, 2017, 14 hours before that. Set to.

In addition, the irradiation period setting unit 219c of the present embodiment may set, as the irradiation end time, the date and time after the wake-up from the irradiation start date and time in the morning period.

For example, in the case where the morning period after getting up is 4 hours and 15 minutes as in the above example, and the desired bedtime is set to 24:00 on December 1, 2017, the irradiation period setting unit 219c The irradiation start date and time is set to 10:00 on December 1, 2017, 14 hours before, and the irradiation end date and time is 14:15 on December 1, 2017, 4 hours and 15 minutes after that.

On the other hand, in order to adjust the circadian rhythm to a normal state and maintain and improve mental and physical health, except for the case where a sleep prohibition period is set, the user's eyes are exposed to daylight hours (ie, sunrise). It is desirable to irradiate BL and VL during the time period from the time until sunset.

In particular, in the case of after-night work, etc., forcibly adjusting the circadian rhythm in a short period of time (for example, one day to several days) and returning to the normal rhythm of life will maintain and improve mental and physical health. Important above.

In such a case, if the user's eyes are irradiated with BL and VL after sunset, the amount of melatonin secretion does not increase at the usual bedtime, and it may be difficult to return to the normal rhythm in a short time. There is.

Therefore, in the present embodiment, the irradiation period setting unit 219c specifies the date and time of sunset at the location of the user based on the sunshine information acquired by the data acquisition unit 219a, and sets the morning period after waking up from the irradiation start date to sunset. If it is not possible to secure an irradiation period equal to, the sunset date and time are set as the irradiation end date and time, and the irradiation periods of BL and VL are shortened.

With this configuration, in the present embodiment, the irradiation period setting unit 219c can prevent the VL and BL from being irradiated to the user's eyes during a time period after sunset, so that the circadian rhythm is corrected in a short time. You can do it.

(Irradiation control unit)
When detecting the arrival of the irradiation start date and time set by the irradiation period setting unit 219c while interlocking with the timer 218, the irradiation control unit 219d transmits an irradiation start command to the wearable device 10 and controls the light sources 11 and 12. The LEDs 11B, 11V, 12B and 12V emit light.

At this time, the irradiation control unit 219d reads the condition data stored in the irradiation control data storage unit 213c, and stores the irradiance (that is, BL is 160 μW / cm ² and VL is 80 μW / cm ² ) defined by the condition data. The designated irradiation start command is transmitted to the wearable device 10 via the I / O interface unit 212.

(4) Upon detecting the arrival of the irradiation end date and time, the irradiation control unit 219d transmits an irradiation end command to the wearable device 10, and turns off the LEDs 11B, 11V, 12B, and 12V.

(4) The irradiation control unit 219d further generates irradiation history data based on the irradiation period and the condition data set by the irradiation period setting unit 219c, and stores the generated irradiation history data in the irradiation history data storage unit 213b.

(Transmission processing unit)
At a predetermined timing (for example, every day at 24:00, every Sunday at 24:00, etc.), the transmission processing unit 219e operates in conjunction with the irradiation history data stored in the irradiation history data storage unit 213b in cooperation with the network communication unit 211. A process for uploading the activity schedule data stored in the schedule data storage unit 213d to the information management server device 30 is executed.

At this time, the transmission processing unit 219e uploads a user ID for identifying each user in the communication system S in association with these data.

The information management server device 30 manages the irradiation history data and the action schedule data uploaded from the communication terminal device 20 in this manner in association with the user ID, and later provides advice from a doctor, a parent, or another protection officer. For example, when each data is used, it is managed to be able to specify which user each data corresponds to.

[4.5] Operation of Communication Terminal Device Next, processing executed in the communication terminal device 20 of the present embodiment will be described with reference to FIG. FIG. 10 is a flowchart illustrating processing executed by the application execution unit 219 of the communication terminal device 20 according to the present embodiment.

First, in the communication terminal device 20 of the present embodiment, the action schedule data generation unit 219b generates action schedule data by executing action schedule data generation processing, and stores the generated action schedule data in the action schedule data storage. It is stored in the unit 213d (step Sa1).

Next, the irradiation period setting section 219c extracts a desired bedtime and a sleep prohibition period included in the action schedule data (step Sa2).

Next, the irradiation period setting unit 219c executes an irradiation period setting process to set the irradiation periods of BL and VL (Step Sa3).

The operation at this time is the same as described above. When the sleep schedule is included in the action schedule data, the period is set as the irradiation period as it is, and when the irradiation period is not included. , The irradiation start time is set to 14 hours before the desired bedtime and the morning period after getting up is calculated, and the irradiation end time is set.

(5) At this time, the irradiation control unit 219d operates in conjunction with the timer 218 to detect the current time, and shifts to a state of waiting for the irradiation start time to arrive.
