A single lighting device 200 may be arranged in the private room space, but a visual effect can be obtained by installing a plurality of lighting devices 200 .

The video output device 300 is a device that outputs a still image or a moving image in the private room space. For this purpose, the video output device 300 includes, for example, a display device such as an LCD (liquid crystal display) or an OLED (organic EL display) that is attached to the wall surface of the private room space, or a projector that projects video into the private room space. . There are no restrictions on the size of the display surface of the display device or the size of the image projected by the projector, but a large size that covers the entire visual field of the user can provide a better visual effect. Note that the video output device 300 may output sound related to the output video together with the video.

The control device 400 is a device that controls the illuminance or color temperature of the lighting device 200 and the output of still or moving image output from the image output device 300 . The control device 400 controls the lighting device 200 and the image output device 300 based on an operation instruction by the user to the operation device 500 or an automatic operation starting from detection by the user detection device 600 .

FIG. 3 is a diagram schematically showing a conceptual diagram of control executed by the control device in the environment control system for private room space according to the embodiment of the present invention. The refresh control executed by the control device of the present invention will be described below with reference to FIG.

The refresh control 460 executes the relaxation control 420 to put the user in a relaxed state once, and immediately after that, the awakening control 440 is executed to put the user in a concentration state in which the user can concentrate on work again. Control.

The relax control 420 comprises an illumination relax control 422 by the lighting device 200, a video relax control 424 by the video output device 300, and a combined relax control 426 that overlaps the periods during which the lighting relax control 422 and the video relax control 424 are performed.

The lighting relaxation control 422 reduces the visual stimulation given to the user in the private room space by changing the illuminance of the lighting device 200 to low illuminance or changing the color temperature to a low color temperature such as a warm color system. Control. As a result, the human mental state is guided to the relaxation side where the parasympathetic nerve is dominant, and the body is calmed down.

The video relaxation control 424 is for video (first video) in which the amount of appearance of alpha waves is small and the attenuation of alpha waves does not appear remarkably when an alpha attenuation test (AAT) is performed. This is control for causing the output device 300 to output. As a result, the person's mental state shifts to the relaxation side in which the parasympathetic nerves are dominant.

In addition, the alpha wave attenuation test utilizes the characteristic that the amount of alpha wave appearance when the eyes are closed at rest and the attenuation of alpha waves when the eyes are open fluctuate according to the activity level of the living body. This is an evaluation method that numerically indexes the activity level of the living body from the amount of appearance of alpha waves generated by repetition and the attenuation of alpha waves. For example, an image suitable for image relaxation control can be selected by performing this test after showing an arbitrary image for a predetermined period to determine the activity level of the living body.

As a result of this test, it was found that an image suitable as an image to be output in the image relaxation control 424 is, for example, an image of a natural forest, which has a low color temperature, has no movement, or has little movement, and is therefore visually stimulating. It was a video with little stress, and a video that evokes a psychophysiological reaction that leads the body to the relaxation side by reminding the average person of peace and tranquility.

The combined relaxation control 426 is control that overlaps the periods during which the lighting relaxation control 422 and the video relaxation control 424 are executed. Thereby, a plurality of different visual stimuli by the lighting device 200 and the video output device 300 are interlocked, and a synergistic effect can be obtained. Therefore, by executing the combined relaxation control 426, it is possible to calm the user's body in a shorter period of time than when only the lighting relaxation control 422 or the video relaxation control 424 is executed.

Awakening control 440 includes lighting wake-up control 442 by lighting device 200, video wake-up control 444 by video output device 300, and compound wake-up control 446 that overlaps the period of execution of lighting wake-up control 442 and video wake-up control 444.

The lighting awakening control 442 increases the visual stimulus given to the user in the private room space by changing the illuminance of the lighting device 200 to a high illuminance or changing the color temperature to a high color temperature such as a cool color system. Control. As a result, the human mental state is guided to the arousal side where the sympathetic nerve is dominant, and the living body is activated.

The video awakening control 444 outputs a video (second video) in which a large amount of alpha waves appear and the attenuation of the alpha waves is remarkable when an alpha attenuation test (AAT) is performed. This is the control to output to the device 300 . As a result, the person's mental state shifts to the arousal side in which the sympathetic nerves are dominant.

As a result of this test, it was found that an image suitable as an image to be output in the image arousal control 444 is, for example, an image of a natural sea, which has a high color temperature and motion, and therefore has a lot of visual stimulation. In other words, images that evoke tension, anxiety, curiosity, and inquisitiveness in the average person induce psychophysiological reactions that lead the body to the arousal side.

The compound awakening control 446 is a control that overlaps the periods during which the lighting awakening control 442 and the image awakening control 444 are executed. Thereby, a plurality of different visual stimuli by the lighting device 200 and the video output device 300 are interlocked, and a synergistic effect can be obtained. Therefore, by executing the combined awakening control 446, it is possible to activate the user's body in a shorter time than when only the lighting awakening control 442 or the image awakening control 444 is executed.

FIG. 4 is a flow chart showing an example of refresh control executed by the control device in the private room environment control system according to the embodiment of the present invention. The control flow in the private room space environment control system according to the embodiment of the present invention will be described below with reference to FIG.

In step S401, the user detection device 600 detects the presence of a user in the private room space. Accordingly, when it is detected that the user has entered the private room space, the process proceeds to the next step S402.

In step S402, if the control device 400 stores the control to be automatically executed based on the detection result of the user detection device 600 (step S402, Yes), the process proceeds to step S405, and the control is stored in the storage unit 404. See the control settings for each control.

In step S402, if control to be automatically executed based on the detection result of the user detection device 600 is not stored in the control device 400 (step S402, No), the process proceeds to steps S403 and S404, and the operation device 500 waits until it receives a control signal generated by

In step S403, when the first control signal for executing control based on the control settings stored in the storage unit 404 is generated from the user (step S403, Yes), the process proceeds to step S405 and is stored in the storage unit 404. See the control settings for each control specified.

In step S404, when a second control signal for performing control based on the user's operation on the operation device 500 is generated (step S404, Yes), the process proceeds to step S406, where the user's operation on the operation device 500 is performed. refer.

Refers to the control settings such as the contents of the video output when executing, the order of executing each control, and the length of the execution period of each control.

Then, the control device 400 starts executing the refresh control 460 based on the control settings referred to in step S405 (steps S407 to S414).

The refresh control 460 first executes the relaxation control 420 (steps S408 to S410), and then executes the awakening control 440 (steps S411 to S413).

If a second control signal for executing control based on the user's manipulation of the operation device 500 is generated during execution of the relaxation control 420 or the awakening control 440 (step S409 or step S412, Yes), the process proceeds to step S406. do.

In step S406, the lighting device 200 and the video output device 300 can be controlled by the user's operation on the operating device 500. FIG. As a result, for example, if the relaxation control 420 or the wakefulness control 440 based on the control settings stored in the storage unit 404 does not suit the user's preference, the user's mood of the day is stored in the storage unit 404. It is possible to end each control in the middle by executing control different from the control setting or cutting off the control instruction to the lighting device 200 or the video output device 300 in the middle.

FIG. 5 is a flowchart showing an example of relaxation control executed by the control device during refresh control in the private room environment control system according to the embodiment of the present invention.
FIG. 6 is a flowchart showing an example of awakening control executed by the control device during refresh control in the private room environment control system according to the embodiment of the present invention.
A control flow of relaxation control and awakening control in the environment control system for private room space according to the embodiment of the present invention will be described below with reference to FIGS. 5 and 6. FIG.

When executing the refresh control 460 based on the first control signal or automatic operation, the control device 400 sends a control instruction corresponding to the lighting relax control setting 421 to the lighting device 200 and executes the lighting relax control 422. (Step S502). After executing the relaxation control 420, the control device 400 transmits a control instruction corresponding to the lighting awakening control setting 441 to the lighting device 200, and executes the lighting awakening control 442 (step S602).

Then, when the illuminance or color temperature in the private room space changed by the lighting device 200 reaches the illuminance or color temperature stored in the relaxing lighting control setting 421 (step S503, Yes), the control device 400 The video content stored in the relaxation control setting 423 is transmitted to the video output device 300, and the video relaxation control 424 is executed (step S504).

Further, when the lighting device 200 causes the illuminance or color temperature in the private room space to reach the illuminance or color temperature stored in the lighting awakening control setting 441 (step S603, Yes), the control device 400 changes the visual awakening control setting. The video contents stored in 443 are transmitted to the video output device 300, and the video relaxation control 424 is executed (step S604).

The order in which control device 400 transmits control instructions to lighting device 200 and video output device 300 may be that video output device 300 is sent first and lighting device 200 is sent later.

After that, the control device 400 executes each control by the lighting device 200 and the video output device 300 over a predetermined period according to the control settings regarding the execution period of each control stored in the storage unit 404 (steps S505 and S605). ).

Then, after the execution period stored in the video relaxation control setting 423 or the video awakening control setting 443 has elapsed, the control device 400 transmits a stop instruction to the video output device 300 to perform the video relaxation control 424 or the video awakening control. 444 ends (step S506 or step S606).

Similarly, after the execution period stored in the video relaxation control setting 423 or the video awakening control setting 443 has elapsed, the control device 400 transmits a stop instruction to the lighting device 200 and controls the lighting relaxation control 422 or the lighting awakening control 442. is terminated (step S507 or step S607).

FIG. 7 is a diagram showing an example of a time chart of refresh control executed by the control device in the environment control system for private room space according to the embodiment of the present invention. Hereinafter, a time chart of refresh control in the space control system for private room space according to the embodiment of the present invention will be described with reference to FIG.

When the user performs an operation to turn on the lighting device 200 provided in the private room space, the lighting device 200 lights with the normal illuminance and color temperature (t ₀ ). The illuminance and color temperature in the private room space at this time are, for example, 160Lx (lux) and a color temperature of 4000K (Kelvin).

After that, when the first control signal is generated for the operating device 500, or when the user detection device 600 detects the presence of the user in the private room space, the automatic operation is stored. If so, the control device 400 refers to the control settings stored in the storage unit 404 and starts executing the refresh control 460 .

The control device 400 controls the illuminance or color temperature of the lighting device 200 by transmitting a control instruction based on the lighting relaxation control setting 421 to the lighting device 200, and performs lighting relaxation control 422 that lowers the illuminance or color temperature in the private room space. (t ₁ ). In lighting relaxation control 422 , control device 400 controls the illuminance or color temperature to be lower than the normal illuminance or color temperature before execution of relaxation control 420 . At this time, the illuminance and color temperature in the private room space lowered by the lighting device 200 are, for example, 60Lx and a color temperature of 2700K.

It should be noted that in the lighting relaxation control 422, it is preferable not to reduce the illuminance in the private room space to zero. The closer the illuminance in the private room is to zero, the less visual stimuli there will be and the more the effect of calming the living body can be enhanced. be.

Then, when the execution period of the relaxing lighting control 422 has passed a pre-programmed predetermined period, or the illuminance or color temperature in the private room space lowered by the relaxing lighting control 422 reaches the pre-programmed illuminance or color temperature. At this time, the control device 400 transmits a control instruction based on the video relaxation control setting 423 to the video output device 300 . Then, image relaxation control 424 for outputting an image with a low color temperature such as a warm color or an image that has the effect of inducing a psychophysiological reaction such as comfort and tranquility in a person is started (t ₂ ). At this time, the image output by the image output device 300 is, for example, an image of a forest.

After that, the control device 400 executes combined relaxation control 426 in which the lighting relaxation control 422 and the video relaxation control 424 are executed in overlapping periods based on the execution period of each control setting stored in the storage unit 404 ( t2 _{- t3} ). At this time, the compound relaxation control 426 is executed for 3.5 minutes, for example.

After executing the composite relaxation control 426 and after the execution period of each control stored in the storage unit 404 expires, the control device 400 transmits a stop instruction to the video output device 300 and terminates the video relaxation control 424 (t ₃ ). At this time, the control device 400 controls the illuminance or color temperature of the lighting device 200 by transmitting a control instruction based on the lighting awakening control setting 441 to the lighting device 200, thereby increasing the illuminance or color temperature in the private room space. Execution of wake-up control 442 is started.

Note that if the image awakening control 444 is executed during the execution period of the lighting relaxation control 422, the difference in illuminance between the illuminance in the private room space and the image output by the image output device 300 increases, causing the user to There is a risk of receiving too strong a visual stimulus. Therefore, it is preferable to set the execution period of the lighting relaxation control 422 stored in the lighting relaxation control setting 421 and the execution period of the visual awakening control 444 stored in the visual awakening control setting 443 so as not to overlap each other.

Then, when the execution period of the lighting awakening control 442 has passed a pre-programmed predetermined period, or the illuminance or color temperature in the private room space raised by the lighting awakening control 442 reaches the pre-programmed illuminance or color temperature. At this time, the control device 400 transmits a control instruction based on the video awakening control setting 443 to the video output device 300 . Then, image awakening control 444 for outputting an image with a high color temperature such as a cool color or an image that has the effect of causing a psychophysiological reaction such as tension, anxiety, curiosity, or inquisitiveness is started (t ₄ ). . At this time, the illuminance and color temperature in the private room space raised by the lighting device 200 are, for example, 400Lx and a color temperature of 4800K, and the image output by the image output device 300 is, for example, an image of the sea.

In addition, in the illumination awakening control 442, if the illuminance in the private room space is increased, the visual stimulus is increased, and the effect of activating the living body can be enhanced. Therefore, the illuminance stored in the lighting awakening control setting 441 is preferably set to be at least higher than the illuminance in the private room space during normal times. That is, it is preferable to set such that the illuminance of the private room space during normal times<the illuminance of the private room space during lighting awakening control 442 .

Furthermore, the relationship between the illuminances stored in the lighting relaxation control setting 421 and the lighting awakening control setting 441 is based on the first illuminance difference, which is the difference between the normal illuminance and the illuminance stored in the lighting relaxation control setting 421. is preferably set so that the second illuminance difference, which is the difference between the normal illuminance and the illuminance stored in the lighting awakening control setting 441, is larger. That is, the first illuminance difference (the illuminance in the private room space during normal times - the illuminance in the private room space during lighting relaxation control 422) < the second illuminance difference (the illuminance in the private room space during lighting awakening control 442 - during normal times illuminance in the private room space). This can enhance the refresh effect.

After that, the control device 400 executes the combined awakening control 446 that overlaps the period of executing the lighting awakening control 442 and the image awakening control 444 based on the execution period of each control setting stored in the storage unit 404 ( t4 _{- t5} ). At this time, the complex arousal control 446 is executed for 1.5 minutes, for example.

Note that the relationship between each control setting stored in the lighting relaxation control setting 421 and the lighting awakening control setting 441 is the difference between the illuminance in the private room space during normal times and the illuminance stored in the lighting relaxation control setting 421. The difference between the illuminance stored in the lighting relax control setting 421 and the illuminance stored in the lighting awakening control setting 441 is greater than the relaxation stimulus value, which is the result of multiplying the illuminance difference by the execution period stored in the lighting relax control setting 421 . It is preferable to set the awakening stimulus value, which is the result of multiplying the third illuminance difference, which is the difference, by the execution period stored in the lighting awakening control setting 441, to be larger. In other words, it is preferable to set the relaxation stimulus value (first illumination difference×execution period of lighting relaxation control 422)<wake stimulus value (third illumination difference×execution period of lighting awakening control 442). This can further enhance the refreshing effect.

In addition, the arousal control 440, which has the effect of activating the body, is a control that increases the visual stimulus to the user, so the body reacts immediately, whereas the relaxation control 420, which has the effect of calming the body, Since the control reduces the visual stimulus to the user, the body reacts slowly.

Therefore, the relationship between the execution periods stored in the lighting relaxation control setting 421 and the lighting awakening control setting 441 is such that the execution period of the lighting relaxation control 422 is equal to or shorter than the execution period of the lighting awakening control 442. It is preferable to set In other words, it is preferable to set the execution period of the lighting relaxation control 422≧the execution period of the lighting awakening control 442 . As a result, the period of application of the relaxation control 420, which requires a relatively long period of time, is lengthened, so that the user's body can be calmed down effectively in a short period of time.

After executing the compound awakening control 446 and after the execution period of each control stored in the storage unit 404 expires, the control device 400 transmits a stop instruction to the lighting device 200 and the video output device 300, and performs the lighting awakening control 442 and the video. Awaken control 444 ends (t ₅ ).

When the illuminance or color temperature in the private room space reaches the normal illuminance or color temperature, the refresh control 460 by the control device 400 ends (t ₆ ).

FIG. 8 is a diagram showing the results of physiological measurements of subjects with respect to the refresh control executed by the control device in the demonstration test of the environment control system for a private room space according to the present invention. The results of the demonstration test will be described below with reference to FIG.

In order to verify the effects of the refresh control 460 described above, the inventors performed physiological measurements based on pulse waves.

The inventors prepared a private room in which the illumination device 200 and the video output device 300 were installed as an environment for the demonstration test. Subjects were instructed to remain as still as possible during the test. Then, a pulse wave measuring instrument TN1012/ST manufactured by BRC Bio Research Center Co., Ltd. was attached to the fingertip of the subject to measure the pulse wave.

Physiological measurement based on the pulse wave divides the measured pulse wave into a low frequency component (LF) and a high frequency component (HF). It is said that the parasympathetic nervous system is dominant and is in a relaxed state.

The illuminance and color temperature in the private room space are measured by placing a spectral irradiance meter CL-500A manufactured by Konica Minolta Co., Ltd. on the floor vertically below the lighting device 200, and directing its light receiving part toward the lighting device 200. It was measured by

In the demonstration test, first, in order to have the subject reproduce the same mental state as when working in the office, a video with sound simulating the office was output outside the private room space, and from a predetermined number Subjects were tasked with answering orally for 5 minutes an arithmetic problem involving subtraction of two-digit numbers. At this time, the subject was asked to watch the video with the sound from inside the private room, which was made open by opening the door. The illuminance and color temperature in the private room space at this time were set to 160Lx and a color temperature of 3400K, imitating the illuminance and color temperature in the private room space during normal times.

Next, the private room space was closed by closing the door while stopping the output of the video with sound simulating the office. At this time, the illuminance and color temperature in the private room space were kept at 160Lx and a color temperature of 3400K.

In the subsequent demonstration test, when reproducing the user's mental state by executing the lighting relaxation control 422, the lighting device 200 was controlled to lower the illuminance in the private room space to 60Lx and the color temperature to 2700K. . When reproducing the mental state of the user by executing the image relaxation control 424, the image output device 300 was controlled to output the image of the forest in the private room space.

Also, when reproducing the mental state of the user by executing the lighting awakening control 442, the lighting device 200 was controlled to raise the illuminance in the private room space to 400Lx and the color temperature to 4800K. When reproducing the mental state of the user by executing the image awakening control 444, the image output device 300 was controlled to output the image of the sea in the private room space.

There were three evaluation conditions for the refresh control 460, and the relaxation control 420 and the awakening control 440 were executed for 5 minutes in all evaluation conditions. The details of the three conditions evaluated are as follows.
Under evaluation condition 1, only lighting relaxation control 422 was executed in relaxation control 420, and only lighting wakefulness control 442 was executed in wakefulness control 440. FIG.
