Description

[Technical field]

[0001] The present invention relates to a lighting device and a lighting device control program. [Background technology]

[0002] Melatonin is a sleep hormone secreted from the pineal gland in the brain. Secretion of melatonin promotes the onset of sleep. On the other hand, when secretion of melatonin is suppressed, the onset of sleep is inhibited.

[0003] It is known that melatonin secretion is affected by light. Technologies related to lighting devices that emit light that does not suppress melatonin secretion and promote sleepiness in users have been proposed (see, for example, Patent Documents 1 and 2). The proposed lighting devices change the color temperature of the light they emit from a high color temperature to a low color temperature. As a result, the effect of light suppressing melatonin secretion is reduced. In other words, the lighting device promotes melatonin secretion and promotes smooth sleep onset.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a lighting device (hereinafter referred to as "the device") and a lighting device control program (hereinafter referred to as "the program") according to the present invention will be described below with reference to the drawings.

[0010] ●Network configuration of this device● FIG. 1 is a network configuration diagram showing an embodiment of the present device and the present program. The figure shows that the device 1, a user terminal 2, and an external sensor 3 are mutually connected via a communication network N so as to be able to communicate with each other.

[0011] The device 1 includes two light sources (hereinafter collectively referred to as "light sources"). The device 1 is a bedside light. The device 1 controls the light emission mode of each light source individually. The light emission mode is a characteristic of the light emitted by each light source. The light emission mode is at least one of the light emission amount and the color temperature.

[0012] The device is not limited to a bedside light, but may also be a ceiling light.

[0013] Furthermore, the number of light sources included in the present device is not limited to two. That is, for example, the present device may include three or more light sources.

[0014] The user terminal 2 is an information processing terminal operated by a user of the present device 1, that is, a person who wishes to use the present device 1 to obtain effects such as promoting sleep. The user terminal 2 generates information necessary for the operation of the present device 1 (hereinafter referred to as "operation information"). Alternatively, the user terminal 2 transmits and receives information between the present device 1 and each of the external sensors 3. The user terminal 2 is a smartphone. The user terminal 2 executes the present program. The present program operating on the user terminal 2 cooperates with the hardware resources of the user terminal 2 to realize control of the light emission amount of each of the two light sources equipped in the present device 1.

[0015] The hardware resources of the user terminal 2 are, for example, processors such as a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), etc. The processor executes instructions written in the program to realize each of the means, which will be described later, provided in the user terminal 2.

[0016] The user terminal may be any device capable of controlling the operation of each of the multiple light sources provided in the device (described later), and may be, for example, a personal computer, a tablet terminal, or a wristwatch-type portable information terminal.

[0017] The external sensor 3 detects at least one of a user state and an external environmental state. The external sensor 3 outputs (transmits) detection information indicating the result of detection by the external sensor 3 to the device 1 and the user terminal 2. The user state and the external environmental state will be described in detail later.

[0018] The external sensor is the first sensor in the present invention. The first sensor is, for example, a Doppler sensor, a temperature sensor, an air pressure sensor, a sound sensor, a light sensor, an acceleration sensor, a position sensor, a positioning sensor, an odor sensor, or the like. The first sensor may include a plurality of sensors.

[0019] The communication network N is a communication line in the present invention. The communication line is, for example, the Internet or a LAN (Local Area Network).

[0020] ●Light emission mode● The light emission modes include a first light emission mode and a second light emission mode (hereinafter collectively referred to as "plural light emission modes"). The first light emission mode is the light emission mode of the first light source (11α). The second light emission mode is the light emission mode of the second light source (11β). The light emission modes are controlled by the control unit (17) based on a control amount. Here, numbers in parentheses (such as "11α") indicate the symbols of each component included in the device 1 or user terminal 2 shown in FIG. 3 (the same applies below).

[0021] When the light emission mode is the amount of light emitted, the light emission mode can be controlled to, for example, turn off all the lights, dim the light, brighten the light, turn on all the lights, change the cycle of increasing and decreasing the amount of light emitted, maintain the amount of light emitted, and so on.

[0022] When the light emission mode is color temperature, the control of the light emission mode is, for example, increasing the color temperature or decreasing the color temperature.

[0023] The color temperature is, for example, daylight color, natural white, warm white, incandescent color, etc., which are approximately 6500K, approximately 5000K, approximately 4200K, approximately 3500K, and approximately 3000K, respectively. The color temperature includes a first color temperature and a second color temperature. The first color temperature is the color temperature of the light emitted by the first light source (11α). The second color temperature is the color temperature of the light emitted by the second light source (11β). The first color temperature is different from the second color temperature.

[0024] Furthermore, the color temperature of light that is less effective in suppressing melatonin secretion is, for example, about 2800K to about 3000K. The color temperature of light that is more effective in suppressing melatonin secretion is, for example, about 4500K to about 7500K. Light with a high color temperature (for example, daylight white of about 5000K) suppresses melatonin secretion more than light with a low color temperature (for example, incandescent light of about 3000K). A user's sleep may be disturbed if the user is exposed to light with a high color temperature at night.

[0025] In the following description, the light emission mode in this embodiment is the amount of light emitted, that is, the device 1 controls only the amount of light emitted, and does not control the color temperature.

[0026] ● Operation information ● FIG. 2 is a schematic diagram showing the relationship between pieces of information included in the operation information. The operation information includes detection information, storage information, operation information, light emission information, a change amount, and a control amount. This figure shows that the light emission information is generated based on the detection information, the storage information, and the operation information. This figure shows that the light emission information is updated based on the detection information and the stored information. This figure shows that the first change amount and the second change amount are determined based on light emission information. The figure shows that the first control amount is determined based on the first change amount, and that the second control amount is determined based on the second change amount. The figure shows that a first light emission manner is controlled based on a first controlled variable, and a second light emission manner is controlled based on a second controlled variable.

[0027] ●Light emission information The light emission information is information related to the amount of light emitted by the light source (11). The light emission information is, for example, a rate of change in the amount of light emitted, a control time, and the like. The light emission information is generated by the light emission information generation unit (14) based on at least one of the detection information, the storage information, and the operation information. The light emission information is updated by the light emission information update unit (15) based on at least one of the detection information and the storage information.

[0028] The light emission amount is the amount of light emitted by the light source (11). The light emission amount includes a first light emission amount and a second light emission amount. The first light emission amount is the light emission amount of the first light source (11α). The second light emission amount is the light emission amount of the second light source (11β).

[0029] The rate of change in the amount of light emitted is the ratio of the amount of light emitted after the increase or decrease to the amount of light emitted before the increase or decrease. When the amount of light emitted becomes 1.5 times, the rate of change in the amount of light emitted is 50%. When the amount of light emitted becomes 0.25 times, the rate of change in the amount of light emitted is -75%.

[0030] The control time is the time during which the amount of light emitted is controlled so as to change. The control time is the time from when the control of the amount of light emitted starts until the light source (11) is turned on at a specified darkness or completely turned off. That is, for example, the control time is the time from when the user operates the operation unit (23) of the user terminal (2) until the light source (11) is completely turned off. The control time is also the time from when the control of the amount of light emitted starts until the light source (11) is turned on at a specified brightness or completely turned on. Furthermore, the control time is a time that is determined based on information related to the heart rate detected by a sensor (22) that detects information related to the user's heart rate. The control time includes a standby time.

[0031] It should be noted that the start of the control time in the present invention is not limited to when the user operates the operation unit (23) of the user terminal (2). That is, for example, the start of the control time in the present invention may be determined based on past light emission information stored in the storage units (10, 21). For example, the start of the control time in the present invention may be determined based on detection information indicating the results of detection by the external sensor (3) and the sensors (12, 22).

[0032] The standby time is the time from when the control of the amount of light emitted starts to when the amount of light emitted starts to change. That is, for example, the standby time is the time from when the user operates the operation unit (23) of the user terminal (2) to when the amount of light emitted by the light source (11) starts to decrease. The standby time is included in the control time. The standby time is included in the control time that is generated based on the detection information that indicates the result of detection by the sensor (22).

[0033] The sensor that outputs the detection information used to generate the control time including the standby time in the present invention is not limited to the sensor included in the user terminal. That is, for example, the sensor that outputs the detection information used to generate the control time including the standby time in the present invention may be the external sensor (3) or the sensor (12).

[0034] ●Control amount The control amount is a physical amount related to the control of the amount of light emitted. The control amount is a current value of a current supplied to the light source (11). The control amount includes a first control amount and a second control amount (hereinafter collectively referred to as "multiple control amounts"). The first control amount is a control amount related to the control of the first amount of light emitted. The first control amount is a current value (first current value) of a current supplied to the first light source (11α). The second control amount is a control amount related to the control of the second amount of light emitted. The second control amount is a current value (second current value) of a current supplied to the second light source (11β). The control amount is determined by the control unit (17) based on the change amount.

[0035] In this way, the current value of the current supplied to each light source is determined by the control unit (17) based on the amount of increase or decrease in the current value of the current supplied to each light source.

[0036] The controlled variable in the present invention is not limited to the current value. That is, for example, the controlled variable in the present invention may be a voltage value supplied to each light source, a signal related to the wavelength of light from each light source, a signal related to the frequency of light from each light source, etc.

[0037] ●Amount of change The change amount is the difference between the control amount before the change and the control amount after the change. The change amount is the amount of increase or decrease in the current value of the current supplied to the light source (11). The change amount is the amount of increase in the current value of the current supplied to the light source (11) when the rate of change in the amount of light emitted, which is the light emission information, is positive. The change amount is the amount of decrease in the current value of the current supplied to the light source (11) when the rate of change in the amount of light emitted, which is the light emission information, is negative. The change amount includes a first change amount and a second change amount (hereinafter collectively referred to as "multiple change amounts"). The first change amount is the change amount of the first control amount (the amount of increase or decrease in the first current value). The second change amount is the change amount of the second control amount (the amount of increase or decrease in the second current value). The change amount is determined by the change amount determination unit (16) based on the light emission information. The multiple change amounts are different from each other.

[0038] In this way, the amount of increase or decrease in the current value of the current supplied to each light source is determined by the change amount determination unit (16) based on the common light emission information. The amount of increase or decrease in the current value of the current supplied to each light source is different.

[0039] The amount of change in the present invention is not limited to the amount of increase or decrease in the current value. That is, for example, the amount of change in the present invention may be the amount of increase or decrease in the voltage value supplied to each light source, the amount of change in the signal related to the wavelength from each light source, the amount of change in the signal related to the frequency from each light source, etc.

[0040] Detection information The detection information is information indicating the results of detection output (transmitted) by the external sensor (3) and the sensors (12, 22) that detect at least one of the user state and the external environmental state.

[0041] The user status is the status of the user, such as body movement, heart rate, body temperature, vocalization, pulse rate, and the like.

[0042] The external environmental condition is the condition of the environment in which the device 1 is installed for the user. The external environmental condition is, for example, temperature, humidity, air pressure, brightness, sound, smell, and the like.

[0043] The environment may be, for example, indoors, outdoors, or any other surrounding space.

[0044] Memory information The stored information includes at least one of the detection information stored in the storage unit (10, 21) and the light emission information stored in the storage unit (10, 21).

[0045] ●Operation information The operation information is information indicating the content of an operation performed by a user on the operation unit (13, 23) and information indicating the result of information processing executed by the device 1 or the user terminal 2 in response to the operation.

[0046] Here, the content and result of the operation may be, for example, that the operation unit has been operated by the user.

[0047] ●Configuration of this device● FIG. 3 is a functional block diagram of the device 1 and the user terminal 2. As shown in FIG.

[0048] The device 1 includes a memory unit 10, a light source 11, a sensor 12, an operation unit 13, an illumination information generation unit 14, an illumination information update unit 15, a change amount determination unit 16, a control unit 17, a detection change unit 18, and a communication unit 19.

[0049] The storage unit 10 stores the operation information. Of the information included in the operation information, at least one of the detection information and the light emission information is stored in the storage unit 10 as storage information.

[0050] The light source 11 is a semiconductor light-emitting element such as a light-emitting diode (LED), etc. The light source 11 includes a first light source 11α and a second light source 11β.

[0051] The sensor 12 detects at least one of a user state and an external environmental state. The sensor 12 outputs (transmits) detection information indicating the result of detection by the sensor 12 to a predetermined output destination. The predetermined output destinations are the storage unit 10, the light emission information generation unit 14, the light emission information update unit 15, the detection change unit 18, and the communication unit 19.

[0052] The sensor included in this device is the second sensor of the present invention. The second sensor is, for example, a Doppler sensor, a temperature sensor, an air pressure sensor, a sound sensor, a light sensor, a speed sensor, a position sensor, a positioning sensor, an odor sensor, or the like.

[0053] It should be noted that the second sensor may include a plurality of sensors.

[0054] The operation unit 13 is a means operated by a user (for example, to input information, perform a selection operation, etc.). The operation unit 13 outputs (transmits) operation information based on the operation of the operation unit 13 to the light emission information generation unit 14. The operation unit 13 is a touch panel.

[0055] The operation unit of the device may include a plurality of operation units. The operation unit of the device may output (transmit) operation information based on a user's operation to a storage unit, a light emission information update unit, a communication unit, or the like of the device.

[0056] The light emission information generating unit 14 acquires at least one of the detection information, the storage information, and the operation information. The light emission information generating unit 14 generates light emission information based on at least one of the detection information, the storage information, and the operation information acquired by the light emission information generating unit 14. The light emission information generating unit 14 generates light emission information including a standby time.

[0057] The light emission information update unit 15 acquires at least one of the detection information and the stored information. When it is necessary to update the light emission information to promote the user's falling asleep, the light emission information update unit 15 updates the light emission information based on at least one of the detection information and the stored information acquired by the light emission information update unit 15.

[0058] The change amount determination unit 16 determines the change amount (the amount of increase or decrease in the current value of the current supplied to the light source 11) based on the light emission information. The change amount determination unit 16 includes a first change amount determination unit 161 and a second change amount determination unit 162.

[0059] The first change amount determination section 161 determines the first change amount based on the light emission information.

[0060] The second change amount determination section 162 determines the second change amount based on the light emission information.

[0061] In other words, the change amount determination unit 16 determines each of the multiple change amounts based on the common light emission information. That is, for example, the first change amount determination unit 161 determines the amount of increase or decrease in the first current value based on the light emission information. The second change amount determination unit 162 determines the amount of increase or decrease in the second current value based on the light emission information.

[0062] In this way, the change amount determination unit 16 determines the amount of increase or decrease in the current value of the current supplied to each light source based on the common light emission information.

[0063] The control unit 17 determines a control amount (a current value of a current supplied to the light source 11) based on the change amount. The control unit 17 controls the light emission amount based on the determined control amount. The control unit 17 includes a first control unit 171 and a second control unit 172.

[0064] The first control unit 171 determines a first control amount based on the first change amount. The first control unit 171 controls the first light emission amount based on the determined first control amount.

[0065] The second control unit 172 determines a second control amount based on the second change amount. The second control unit 172 controls the second light emission amount based on the determined second control amount.

[0066] In other words, the control unit 17 controls the light emission amount of each light source based on the common light emission information. That is, for example, the first control unit 171 determines the first current value based on the increase / decrease amount of the first current value. The first control unit 171 controls the first light emission amount based on the determined first current value. The second control unit 172 determines the second current value based on the increase / decrease amount of the second current value. The second control unit 172 controls the second light emission amount based on the determined second current value.

[0067] In this way, the control unit 17 determines the current value of the current supplied to each light source based on the common light emission information, and controls the light emission amount of each light source based on the common light emission information.

[0068] The detection change unit 18 acquires detection information output (transmitted) from at least one of the external sensor 3 and the sensors 12 and 22 (hereinafter collectively referred to as "each sensor") The detection change unit 18 determines whether or not it is necessary to change the operation of each sensor for a predetermined purpose based on the acquired detection information.

[0069] The predetermined purpose is, for example, reducing the power consumption of the sensor, reducing the amount of communication, improving the detection accuracy, optimizing for each user, etc. The detection change unit 18 changes the operation of each sensor.

[0070] The operation of each sensor is, for example, detection once per second, output of detection information once per second, detection once per minute, detection stop, output stop, detection restart, etc. For example, the detection change unit 18 changes the detection once per second by the external sensor 3 to detection stop based on the detection information.

[0071] When it is determined that the operation of each sensor needs to be changed for a predetermined purpose, the detection change unit 18 changes the operation of each sensor based on the acquired detection information. When the detection change unit 18 determines that it is not necessary to change the operation of each sensor for a predetermined purpose, it does not change the operation of each sensor, i.e., the operation of each sensor is maintained. The detection change unit 18 may change the operation of all or only a part of the sensors based on the detection information.

[0072] The communication unit 19 is a wireless communication circuit that realizes communication using a wireless communication method such as radio waves. The communication unit 19 transmits and receives operation information between the communication unit 24 and the external sensor 3. The communication unit 19 receives operation information of the device 1 from a predetermined transmission source and transmits it to the communication unit 24. The predetermined transmission sources are the memory unit 10, the sensor 12, the operation unit 13, the light emission information generation unit 14, and the light emission information update unit 15. The communication unit 19 receives the operation information transmitted by the communication unit 24. The details of the communication unit 24 will be described later.

[0073] ●User device configuration● The user terminal 2 includes a memory unit 21, a sensor 22, an operation unit 23, and a communication unit 24.

[0074] The storage unit 21 stores the operation information.

[0075] Here, at least one of the detection information and the light emission information included in the operation information is stored in the storage unit 21 as storage information.

[0076] The sensor 22 detects at least one of a user state and an external environmental state. The sensor 22 outputs (transmits) detection information indicating a result of the detection by the sensor 22 to the communication unit 24.

[0077] The sensor provided in the user terminal is the third sensor in the present invention. The third sensor is, for example, a Doppler sensor, a temperature sensor, an air pressure sensor, a sound sensor, a light sensor, an acceleration sensor, a position sensor, a positioning sensor, an odor sensor, or the like.

[0078] It should be noted that the third sensor may include a plurality of sensors.

[0079] Furthermore, the third sensor may output (transmit) detection information indicating the result of detection by the third sensor to a storage unit included in the user terminal.

[0080] The operation unit 23 is a device that is operated by a user (for example, to input information, perform a selection operation, etc.). The operation unit 23 outputs (transmits) operation information based on the operation of the operation unit 23 to the communication unit 24. The operation unit 23 is a touch panel.

[0081] The operation unit included in the user terminal may include a plurality of operation units. The operation unit included in the user terminal may output (transmit) operation information based on the user's operation to a storage unit included in the user terminal.

[0082] The communication unit 24 is a wireless communication circuit capable of communication using a wireless communication method such as radio waves.

The communication unit 24 receives operation information output (transmitted) by the sensor 22 and transmits it to the communication unit 19. The communication unit 24 receives operation information transmitted by the communication unit 19.

[0083] The communication unit of the user terminal may receive the stored information stored in the memory unit of the user terminal and transmit it to the communication unit of the device. The operation unit of the user terminal may receive the detection information output (transmitted) by the sensor.

[0084] ●Lighting and control modes of this device● The device 1 has, as its operation modes, a lighting mode and a control mode.

[0085] Lighting Mode The lighting mode is a mode selected by a user when the device 1 is used. The lighting modes include a sleep mode and a wake-up mode. The user selects one of the two lighting modes (sleep mode and wake-up mode).

[0086] The sleep mode is a lighting mode selected by a user when the user wishes to facilitate smooth sleep onset. In the sleep mode, the device 1 controls the amount of light emitted so as to facilitate the user's falling asleep. The amount of change in the sleep mode is the amount of reduction in the current value of the current supplied to the light source 11. That is, in the sleep mode, the device 1 reduces the amount of light emitted so that the light source 11 is turned on at a specified dimness or completely turned off.

[0087] The wake-up mode is a lighting mode selected by a user when the user wishes to promote smooth awakening. In the wake-up mode, the device 1 controls the amount of light emitted so as to promote the user's awakening. The amount of change in the wake-up mode is the amount of increase in the current value of the current supplied to the light source 11. That is, in the wake-up mode, the device 1 increases the amount of light emitted so that the light source 11 is turned on at a predetermined brightness or fully turned on.

[0088] The sleep mode and wake-up mode each include two control modes: heart rate mode and timer mode.

[0089] Control mode The control mode is a mode selected by the user when the user sets the method for determining the control time in the selected lighting mode. The control modes include a heart rate mode and a timer mode. The user selects one of the two control modes (heart rate mode and timer mode).

[0090] The heart rate mode is a control mode in which the control time is determined based on information related to the user's heart rate. When the heart rate mode is selected, the device 1 controls the amount of light emitted for a period of time from when a predetermined standby time has elapsed until a suitable time for the end of a change in the amount of light emitted calculated from the heart rate detected by the sensor 22. The predetermined standby time is the period of time from when the user operates the user terminal 2 to a suitable time for the start of a change in the amount of light emitted calculated from the heart rate detected by the sensor 22. That is, for example, in the heart rate mode of the sleep mode, the device 1 is turned on with a constant light emission amount from the time the user operates the user terminal 2 until the standby time has elapsed at 22:30. After that, the device 1 reduces the light emission amount so that the light source 11 is completely turned off during the period from 22:30 to 23:15, which is the appropriate time for turning off the light calculated from the heart rate detected by the sensor 22.

[0091] The timer mode is a control mode in which the control time is determined based on the user's operation. When the timer mode is selected, the device 1 controls the amount of light emitted for the time from when the user operates the user terminal 2 to the time specified by the user. That is, for example, the device 1 in the timer mode of the sleep mode reduces the amount of light emitted so that the light source 11 is completely turned off between 10 p.m., when the user operates the user terminal 2, and 11 p.m., which is the time specified by the user.

[0092] ●Select lighting mode and control mode FIG. 4-7 is a schematic diagram of a screen displayed on the user terminal 2. As shown in FIG. In each figure, selection of the button images displayed on screens P1, P2, P3, and P4 (hereinafter collectively referred to as "each screen") is achieved by each screen being displayed on a touch panel and the user touching the display area of ​​each image on each screen. The button images M11, M12, M21, M22, 231, 232, 233, and 234 displayed on each screen constitute an operation unit in the present invention.

[0093] FIG. 4 is a schematic diagram of a selection screen displayed on the user terminal 2 for selecting a lighting mode (sleep mode / wake-up mode) and a control mode (heart rate mode / timer mode). The figure shows that button images M11, M12, M21, and M22 are displayed selectably on a screen P1. The figure shows that button image M11 has been selected.

[0094] ●Example of settings when the user selects sleep mode The following description is an example when the device 1 is controlled based on the sleep mode. That is, in the following description, the change amount is the amount of decrease in the current value of the current supplied to the light source 11. The control of the light emission amount of each of the first light source 11α and the second light source 11β ends when the first light source 11α and the second light source 11β are turned off. The light emission information generation unit 14 generates light emission information based on the operation information. The light emission information update unit 15 updates the light emission information based on the detection information. The first color temperature is higher than the second color temperature. The first light source 11α emits light that is highly effective in suppressing the secretion of melatonin. The second light source 11β emits light that is less effective in suppressing the secretion of melatonin.

[0095] When the button image M11 is selected, the user terminal 2 displays a setting screen for the heart rate mode in the sleep mode (screen P2 in FIG. 5, which will be described later).

[0096] When the button image M12 is selected, the user terminal 2 displays a setting screen for the timer mode of the sleep mode (screen P4 in FIG. 7, which will be described later).

[0097] When the button image M21 is selected, the user terminal 2 displays a setting screen for the heart rate mode of the wake-up mode.

[0098] When the button image M22 is selected, the user terminal 2 displays a setting screen for the timer mode of the wake-up mode.

[0099] FIG. 5 is a schematic diagram of a setting screen for the heart rate mode in the sleep mode displayed on the user terminal 2. As shown in FIG. The figure shows that the user's current heart rate detected by the sensor 22 and the scheduled time when dimming of the light source 11 will start (hereinafter referred to as the "dimming start time") are displayed on the screen P2. The figure shows that a button image 231 is displayed selectably on the screen P2. The figure shows that button image 231 has been selected.

[0100] When the button image 231 is selected, the user terminal 2 transmits to the device 1 information indicating that the button image 231 has been selected by the user.

[0101] That is, operation unit 23 outputs (transmits) operation information based on the user's operation to communication unit 24. Communication unit 24 transmits the output (transmitted) operation information to communication unit 19. This device 1 is controlled in a heart rate mode of a sleep mode (FIG. 14 described later).

[0102] FIG. 6 is a schematic diagram of a notification screen displayed on the user terminal 2. As shown in FIG. The notification screen is a screen that notifies (makes visible to) the user of the start of dimming in the heart rate mode of the sleep mode. The figure shows that the screen P3 displays a notification that dimming has begun due to the heart rate mode of the sleep mode selected in Figure 5, and that the lights are scheduled to be turned off at 11:15 p.m.

[0103] FIG. 7 is a schematic diagram of a setting screen for the timer mode of the sleep mode displayed on the user terminal 2. As shown in FIG. The figure shows that the time when the device 1 is turned off and the amount of light emitted at the time when the dimming starts (the ratio of the amount of light emitted to the maximum amount that the light source 11 can achieve) are displayed on the screen P4. The figure shows that button images 232, 233, and 234 are displayed selectably on a screen P4. The figure shows that button image 232 has been selected.

[0104] When the button image 232 is operated and moved to any position within a predetermined range on the screen P4, the turn-off time of the device 1 displayed on the screen P4 is changed. Similarly, when the button image 233 is operated and moved to an arbitrary position within a predetermined range on the screen P4, the light emission amount at the dimming start time displayed on the screen P4 is changed. When button image 234 is selected after button image 232 and button image 233 have been moved to any position, user terminal 2 transmits to device 1 information indicating that button image 234 has been selected by the user.

[0105] That is, operation unit 23 outputs (transmits) operation information based on the user's operation to communication unit 24. Communication unit 24 transmits the output (transmitted) operation information to communication unit 19. Device 1 is controlled in a timer mode of the sleep mode (FIG. 8 described later).

[0106] ● Timer mode for sleep mode FIG. 8 is a graph showing the change in the amount of light emitted by the device 1 in the timer mode of the sleep mode. In Figures 8-14, the vertical axis indicates the amount of light emitted (lm), and the horizontal axis indicates the elapsed time (s).

[0107] A1 is the light emission amount (first light emission amount) of the first light source 11α.

[0108] B1 is the light emission amount (second light emission amount) of the second light source 11β.

[0109] A1+B1 is the total amount of light emitted of the first amount of light emitted and the second amount of light emitted (hereinafter referred to as the "total amount of light emitted").

[0110] T0 is the start time of the control period of each light source.

[0111] T1 is the time when the first light source 11α is turned off.

[0112] T2 is the time when the second light source 11β is turned off.

[0113] Tx is the time from time T0 to time T2 (control time).

[0114] L0 is the total amount of light emitted at time T2.

[0115] L1 is the first light emission amount at time T0.

[0116] L2 is the second light emission amount at time T0.

[0117] Ls is the total amount of light emitted at time T0.

[0118] The amount of decrease in the value of the current supplied to the first light source 11α determined by the first change amount determination unit 161 is different from the amount of decrease in the value of the current supplied to the second light source 11β determined by the second change amount determination unit 162. The ratio of the amount of decrease in the value of the current supplied to the first light source 11α to the current value supplied before the decrease (hereinafter referred to as the "decrease rate") is greater than the decrease rate of the value of the current supplied to the second light source.

[0119] That is, the ratio of the second light emission amount to the total light emission amount increases as the elapsed time increases. In other words, the effect of suppressing the secretion of melatonin by the light emitted by the light source 11 gradually decreases during the control time Tx. The device 1 gradually reduces the light that suppresses the secretion of melatonin in the user. As a result, the device 1 promotes the user's falling asleep.

[0120] FIG. 9 is a graph showing the change in the amount of light emitted in FIG. 8 superimposed on the change in brightness felt by the user.

[0121] Luminance is the brightness of light as perceived by a user.

[0122] C is the sum of the luminance of the first light source 11α and the luminance of the second light source 11β (the brightness perceived by the user).

[0123] The Weber-Fechner law states that "the magnitude of human sensation is proportional to the logarithm of the intensity of the stimulus received." For example, luminance is proportional to the logarithm of the amount of light emitted. In other words, when the amount of light emitted by the light source 11 decreases based on the Weber-Fechner law, the user feels that the light source 11 is dimming linearly.

[0124] The light source 11 gradually dims during the control time Tx. The light source 11 is turned off at time T2. At this time, the amount of decrease in the total light emission amount becomes smaller with increasing elapsed time. That is, the amount of decrease in the current value of the current supplied to the light source 11 determined by the change amount determination unit 16 becomes smaller with increasing elapsed time.

[0125] Specifically, the total light emission amount decreases so that the logarithm of the total light emission amount is proportional to the luminance based on the Weber-Fechner law. That is, the change amount determination unit 16 determines the amount of decrease in the current value supplied to the light source 11 so that the change in luminance becomes constant. In other words, the present device 1 allows the user to perceive light that decreases steadily with increasing elapsed time. As a result, the present device 1 promotes the user's falling asleep without causing the user to perceive a sudden decrease in light.

[0126] In the present invention, the amount of light emitted does not necessarily have to increase or decrease based on the Weber-Fechner law.

[0127] Timer mode for sleep mode when lighting information is updated FIG. 10 is a graph showing changes in the amount of light emission controlled based on updated light emission information in the timer mode of the sleep mode shown in the graph of FIG.

[0128] FIG. 11 is a graph showing the total amount of light emitted shown in the graph of FIG. 10 superimposed on the total amount of light emitted shown in the graph of FIG.

[0129] FIG. 12 is a graph showing the first amount of light emission shown in the graph of FIG. 10 and the first amount of light emission shown in the graph of FIG. 8 superimposed on each other.

[0130] FIG. 13 is a graph showing the second amount of light emission shown in the graph of FIG. 10 and the second amount of light emission shown in the graph of FIG. 8 superimposed on each other.

[0131] A2 is the first light emission amount when the light emission information is updated.

[0132] B2 is the second light emission amount when the light emission information is updated.

[0133] A2+B2 is the total amount of light emitted when the light emission information is updated.

[0134] Tu is the time when the light emission amount of each light source is controlled based on the updated light emission information.

[0135] T1' is the time when the first light source 11α is turned off when the light emission information is updated.

[0136] T2' is the time when the second light source 11β is turned off when the light emission information is updated.

[0137] Tx' is the time (control time) from time T0 to time T2' when the light emission information is updated.

[0138] As a result of controlling the first light source 11α based on the updated light-emitting information, the turn-off time of the first light source 11α is advanced from time T1 to time T1'. As a result of controlling the second light source 11β based on the updated light-emitting information, the turn-off time of the second light source 11β is advanced from time T2 to time T2'. Therefore, as a result of controlling the light source 11 based on the updated light-emitting information, the turn-off time of the light source 11 is advanced from time T2 to time T2'. That is, the light emission information updated at time Tu includes information regarding shortening the control time Tx determined in FIG. 8 to Tx' (for example, information indicating that the user has started to transition to a sleep state).

[0139] The amount of decrease in the amount of light emitted with respect to the increase in the elapsed time from time Tu to time T2' is greater than the amount of decrease in the total amount of light emitted with respect to the increase in the elapsed time from time Tu to time T2 when the light emission information is not changed (Figure 8). That is, in the period from time Tu to time T2', the amount of decrease in the value of the current supplied to the light source 11 determined by the change amount determination unit 16 is greater than in the case where the light emission information is not changed (FIG. 8).

[0140] In other words, in the period from time Tu to time T2', the effect of suppressing melatonin secretion by the light emitted by the light source 11 decreases more quickly than when the light emission information is not changed (FIG. 8). After time Tu and during the period from time T2', the device 1 quickly reduces the light that suppresses the user's melatonin secretion. In other words, the device 1 updates the light emission information and advances the control time Tx to Tx', thereby further promoting the user's falling asleep.

[0141] ● Heart rate mode in bedtime mode FIG. 14 is a graph showing changes in the amount of light emitted by the device 1 in the heart rate mode of the sleep mode.

[0142] A3 is the first light emission amount in the heart rate mode of the sleep mode.

[0143] B3 is the second light emission amount in the heart rate mode of the sleep mode.

[0144] A3+B3 is the total light output in heart rate mode in sleep mode.

[0145] Ts is the time when the total amount of light emitted starts to change (for example, the time when a heart rate appropriate for falling asleep is detected).

[0146] Ty is the time from time T0 to time Ts (standby time).

[0147] The total amount of light emitted is constant during the standby time Ty, and decreases during the period from time Ts to time T2.

[0148] During the standby time Ty, there is no change in the suppressive effect of the light emitted by the light source 11 on the secretion of melatonin. During the period from time Ts to time T2, the suppressive effect of the light emitted by the light source 11 on the secretion of melatonin decreases. That is, the device 1 determines the control time including the waiting time Ty based on the user's heart rate detected by the sensor 22. In other words, the device 1 promotes the user's falling asleep at a time appropriate for the user. ● Operation of this device ●

[0149] The operation of the device is described below.

[0150] ●Generation of luminescence information by this device FIG. 15 is a flowchart showing the operation of the device 1 when the light emission information generating unit 14 generates light emission information in the timer mode of the sleep mode shown in FIG.

[0151] First, the light emission information generating unit 14 acquires the operation information output (transmitted) from the operation unit 23 (S1).

[0152] Next, the light emission information generating unit 14 generates light emission information based on the acquired operation information (S2).

[0153] Next, the operation of the device 1 branches into an operation of the first change amount determination section 161 (S3) and an operation of the second change amount determination section 162 (S7). The first change amount determination section 161 determines the amount of decrease in the first current value based on the generated light emission information (S3).

[0154] Next, the first control unit 171 determines the first current value based on the determined amount of decrease in the first current value (S4).

[0155] Next, the first control unit 171 controls the first light emission amount based on the determined first current value (S5).

[0156] Next, the first light source 11α is turned off (S6).

[0157] On the other hand, the second change amount determination section 162 determines the amount of decrease in the second current value based on the generated light emission information (S7).

[0158] Next, the second control unit 172 determines the second current value based on the determined amount of decrease in the second current value (S8).

[0159] Next, the second control unit 172 controls the second light emission amount based on the determined second current value (S9).

[0160] Next, the second light source 11β is turned off (S10).

[0161] In this way, when the light emission information generating unit 14 generates the light emission information, the light emission amount of each light source is controlled by the control unit 17 based on the generated common light emission information.

[0162] ● Update of light emission information by this device FIG. 16 is a flowchart showing the operation of the device 1 when the light emission information update section 15 updates the light emission information. This figure shows the operation of the device 1 when already generated light emission information is updated by the operation of the device 1 shown in FIG.

[0163] First, the light emission information update unit 15 acquires the detection information output (transmitted) from the sensor 22 that detects the heart rate of the user (S11).

[0164] Next, the light emission information update unit 15 updates the light emission information based on the detection information acquired by the light emission information update unit 15 in order to promote the user's falling asleep (S12).

[0165] Next, the operation of the device 1 branches into an operation of the first change amount determination section 161 (S13) and an operation of the second change amount determination section 162 (S17). The first change amount determination unit 161 determines the amount of decrease in the first current value based on the updated light emission information (S13).

[0166] Next, the first control unit 171 determines the first current value based on the determined amount of decrease in the first current value (S14).

[0167] Next, the first control unit 171 controls the first light emission amount based on the determined first current value (S15).

[0168] Next, the first light source 11α is turned off (S16).

[0169] On the other hand, the second change amount determination section 162 determines the amount of decrease in the second current value based on the updated light emission information (S17).

[0170] Next, the second control unit 172 determines the second current value based on the determined amount of decrease in the second current value (S18).

[0171] Next, the second control unit 172 controls the second light emission amount based on the current of the determined second current value (S19).

[0172] Next, the second light source 11β is turned off (S20).

[0173] In this manner, when the light emission information update unit 15 updates the light emission information, the light emission amount of each light source is controlled by the control unit 17 based on the updated common light emission information.

[0174] ● Change the operation of the third sensor using this device FIG. 17 is a flowchart showing the operation of the device 1 when the detection change section 18 changes the operation of the sensor 22.

[0175] First, the detection change unit 18 acquires the detection information output (transmitted) from the sensor 22 that detects the heart rate of the user (S21).

[0176] Next, the detection change unit 18 determines whether or not it is necessary to change the operation of the sensor 22 (S22).

[0177] When the result of the determination in S22 is "YES", the detection change unit 18 changes the operation of the sensor 22 based on the acquired detection information (S23).

[0178] On the other hand, when the result of the determination in S22 is "NO", the detection change unit 18 does not change the operation of the sensor 22. In other words, the operation of the sensor 22 is maintained (S24).

[0179] In this manner, when the sensing modifier 18 obtains sensing information, the operation of the sensor 22 is modified for a predetermined purpose.

[0180] ●Summary● As described above, the device 1 determines the first and second change amounts so that the first change amount used to determine the first light emission mode of one light source 11α of the two light sources included in the device 1 is different from the second change amount used to determine the second light emission mode of the other light source 11β. That is, the device 1 can control the light emission amounts of the two light sources based on common light emission information so that the degree of dimming of the first light emission amount is different from the degree of dimming of the second light emission amount. That is, the device 1 can control the light emission amounts of the two light sources so that the degree of dimming of the first light source 11α with a high color temperature is greater than the degree of dimming of the second light source 11β with a low color temperature so that the sleep-promoting effect is enhanced after dimming starts. As a result, the device 1 can promote the user's sleep compared to controlling the light emission amounts of the two light sources so that the degree of dimming of the light emission amounts of the two light sources is the same.

[0181] In addition, the control of the amount of light emitted in the present invention is not limited to the reduction (dimming) of the amount of light emitted. That is, for example, the present device may control the amount of light emitted so that the amount of light emitted by each of the multiple light sources provided in the present device increases (brightens). In this case, the present device can promote the awakening of the user.

[0182] Furthermore, the light emission aspect in the present invention is not limited to the light emission amount alone. That is, for example, the light emission aspect in the present invention may be the color temperature of each of the multiple light sources included in the device alone, or both the light emission amount and the color temperature.
