[Technical Field]

[0001] The present disclosure relates to a lighting system, a lighting control method, and a program, and more particularly to a lighting system, a lighting control method, and a program for controlling a light source. [Background technology]

[0002] As a conventional example, an illumination device described in Patent Document 1 will be exemplified. The illumination device described in Patent Document 1 (hereinafter referred to as the conventional example) includes an illumination unit, an interface unit, a control unit that controls the output of the illumination unit according to a preset dimming schedule according to a set wake-up time, a sensor unit that detects body movements of a sleeping person and outputs the number of body movements detected to the control unit, and a clock unit.

[0003] The control unit has a light sleep determination unit that determines that the sleeper is in light sleep when the number of body movement detections of the sleeper output by the sensor unit per unit time is greater than a predetermined threshold. The control unit stops or reduces the gradual increase in output of the lighting unit when the light sleep determination unit determines that the sleeper is in light sleep between the start and end of the dimming schedule. Thereafter, the control unit gradually increases the output of the lighting unit again when a predetermined period or more has passed during which the light sleep determination unit determines that the sleeper is not in light sleep.

[0004] The above-described conventional example assists the sleeper in waking up comfortably at a timing as close as possible to the set wake-up time without causing discomfort to the sleeper. [Prior art documents] [Patent documents]

[0013] A lighting system, a lighting control method, and a program according to embodiments of the present disclosure will be described in detail below with reference to the drawings. However, the drawings described in the following embodiments are schematic diagrams, and the ratios of the sizes and thicknesses of the components do not necessarily reflect the actual dimensional ratios. Note that the configurations described in the following embodiments are merely examples of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

[0014] (1) Overview (1-1) Overview of the lighting system according to the embodiment The lighting system S1 according to the embodiment includes one or more light source units 10, a control unit 11 that controls the light source units 10, a detection unit 21 that detects the state of an exercising subject H1 (see FIG. 3), an analysis unit 201, and a lighting control unit 202 (see FIG. 1).

[0015] Here, in the present disclosure, the exercise performed by subject H1 refers to exercise consciously performed by subject H1 while awake, such as physical exercise (fitness) performed to promote health or maintain or improve physical strength, exercise (exercise) performed to maintain health or beauty, and exercise (training) to strengthen the body, and does not include unconscious exercise performed by a sleeper, such as turning over in bed.

[0016] The light source unit 10 is variable in at least one of the light intensity and light color. For example, the light source unit 10 has multiple types of LEDs (Light Emitting Diodes) that emit different light colors. As an example, the light source unit 10 has an LED that emits incandescent light and an LED that emits daylight light. However, the light source unit 10 may have light-emitting elements other than LEDs, such as organic EL (Electro Luminescence) elements or laser diodes.

[0017] The control unit 11 controls the light source unit 10 to change at least one of the light intensity and light color of the light source unit 10. The control unit 11 can change the light intensity and light color by increasing or decreasing the current supplied to the light source unit 10.

[0018] The detection unit 21 has, for example, a camera capable of capturing at least one of moving images and still images. The camera included in the detection unit 21 includes an imaging element such as a CMOS (Complementary Metal Oxide Semiconductor) image sensor or a CCD (Charge Coupled Device) image sensor, a lens for focusing light on the light receiving surface of the imaging element, and the like. The detection unit 21 performs so-called markerless motion capture measurement by capturing an image of the body of the subject H1 with the camera. Furthermore, the detection unit 21 detects skeletal information of the subject H1 (the state of the subject H1) based on the measurement results of the motion capture measurement, for example, by using machine learning.

[0019] The analysis unit 201 analyzes the exercise performed by the subject H1 based on the state (skeleton information) of the subject H1 detected by the detection unit 21. For example, the analysis unit 201 analyzes the accuracy of the exercise performed by the subject H1, the number of times the exercise was completed (the number of times the exercise was performed correctly), etc. based on the skeletal information of the subject H1. Then, the analysis unit 201 passes the analysis result of the exercise of the subject H1 to the lighting control unit 202.

[0020] The lighting control unit 202 controls the control unit 11 to change the light output of the light source unit 10 based on the results of the movement analysis by the analysis unit 201. For example, if the accuracy of the movement performed by the subject H1 exceeds a threshold, the lighting control unit 202 causes the control unit 11 to control the light source unit 10 to set the light intensity of the light source unit 10 to a rated value. On the other hand, if the accuracy of the movement performed by the subject H1 is equal to or less than the threshold, the lighting control unit 202 causes the control unit 11 to control the light source unit 10 to set the light intensity of the light source unit 10 to approximately half of the rated value. The subject H1 can recognize the accuracy of his or her movement, the number of times achieved, etc. from changes in the surrounding brightness (lighting environment) without looking directly at the light source unit 10. Note that the lighting control unit 202 may also cause the control unit 11 to control the light source unit 10 to change the light color instead of or in addition to the light intensity.

[0021] Therefore, the lighting system S1 according to the embodiment has the lighting control unit 202 control the control unit 11 to change the light output of the light source unit 10 based on the analysis results of the movement of the subject H1 by the analysis unit 201, thereby realizing a lighting environment that is beneficial to the awake person (subject H1).

[0022] (1-2) Overview of lighting control method according to embodiment The lighting control method according to the embodiment is a lighting control method for controlling the lighting environment of a place where a subject H1 is exercising.

[0023] The lighting control method according to the embodiment includes step ST1 of detecting the state of a subject H1 who is exercising, step ST2 of analyzing the exercise performed by the subject H1 based on the state (of the subject H1) detected in step ST1, and step ST3 of changing the light output of the light source unit 10 based on the analysis result of the exercise (see FIG. 6). According to the lighting control method according to the embodiment, the subject H1 can recognize the accuracy of his / her exercise, the number of times achieved, etc. from changes in the surrounding brightness (lighting environment) without looking directly at the light source unit 10.

[0024] Therefore, the lighting control method according to the embodiment changes the light output of the light source unit 10 based on the analysis result of the exercise performed by the subject H1, thereby realizing a lighting environment that is beneficial to the awake person (subject H1). Note that the lighting control method according to the embodiment may be realized by the lighting system according to the embodiment.

[0025] (1-3) Overview of the program according to the embodiment The program according to the embodiment is a so-called computer program that causes a computer to execute the following steps ST1 to ST3.

[0026] Step ST1 is a step of detecting the state of the exercising subject H1. Step ST2 is a step of analyzing the exercise performed by the subject H1 based on the state (of the subject H1) detected in step ST1. Step ST3 is a step of changing the light output of the light source unit 10 based on the results of the exercise analysis in step ST2. By executing the program according to the embodiment, the subject H1 can recognize the accuracy of his or her exercise, the number of times achieved, etc. from changes in the ambient brightness (lighting environment) without looking directly at the light source unit 10.

[0027] Therefore, the program according to the embodiment changes the light output of the light source unit 10 based on the analysis result of the exercise performed by the subject H1, and therefore, it is possible to realize a lighting environment that is beneficial to an awake person (subject H1).

[0028] (2)Details (2-1) Details of the lighting system according to the embodiment A lighting system S1 according to an embodiment (hereinafter simply referred to as lighting system S1) includes at least one lighting device 1 and a terminal device 2, as shown in FIG.

[0029] (2-1-1) Lighting equipment The lighting device 1 includes one or more light source units 10 and a control unit 11 that controls the light source units 10. The lighting device 1 further includes a sound reproduction unit 12 and a wireless communication unit 13.

[0030] The light source unit 10 includes an LED module having, for example, a plurality of LEDs that emit incandescent light (correlated color temperature of 2700K) and a plurality of LEDs that emit daylight light (correlated color temperature of 6500K). However, the light source unit 10 may also include an LED module that emits light of a color other than incandescent light and daylight light, for example, light of four colors: red, green, blue, and white.

[0031] The control unit 11 has a lighting circuit that lights up the LED module of the light source unit 10, and a control circuit that controls the lighting circuit to increase or decrease the current supplied to the LED module.

[0032] The lighting circuit includes a rectifier that rectifies the AC voltage supplied from the power grid, a power factor correction circuit that boosts and smooths the pulsating voltage output from the rectifier, and two step-down chopper circuits that step down the DC voltage output from the power factor correction circuit. One of the two step-down chopper circuits supplies DC current to multiple LEDs that emit incandescent light, and the other supplies DC current to multiple LEDs that emit daylight light. The control circuit controls the lighting circuit to individually increase or decrease the output current of these two step-down chopper circuits, thereby individually adjusting (dimming and toning) the intensity and color (correlated color temperature) of the light emitted from the light source unit 10.

[0033] As will be described later, the wireless communication unit 13 is configured to wirelessly communicate with the communication unit 26 of the terminal device 2. The wireless communication unit 13 can communicate bidirectionally with the terminal device 2 by performing wireless communication compliant with communication standards such as Wi-Fi (registered trademark) and / or BLE (Bluetooth (registered trademark) low energy).

[0034] The sound reproduction unit 12 includes a speaker unit 93 (see FIG. 2 ) and a drive circuit that drives the speaker unit 93 to reproduce sound (voice, music, etc.). The drive circuit is configured to convert sound data output from the control circuit of the control unit 11 into an analog signal, and then drive the speaker unit 93 with a drive signal obtained by amplifying the analog signal with an amplifier to output (reproduce) sound. However, the sound reproduction unit 12 may be configured with a speaker and drive circuit provided in the terminal device 2. Alternatively, the sound reproduction unit 12 may be a so-called wireless earphone or smart speaker that is wirelessly connected to the terminal device 2.

[0035] The lighting device 1 is, for example, a so-called ceiling light installed on the ceiling X1 of a living room (living room R1) of a house (see FIGS. 2 and 3). However, the lighting device 1 may also be a downlight embedded in the ceiling X1, a so-called desk lamp placed on a table, etc. Alternatively, the lighting device 1 may be a so-called bracket-type lighting device installed on a wall.

[0036] As shown in FIG. 2, the lighting device 1 includes a main body 90, a cover 91, a pair of panels 92, and a pair of speaker units 93.

[0037] The main body 90 is formed from a metal plate such as an aluminum plate into a long box shape with an open bottom. The light source unit 10 and the control unit 11 are housed inside the main body 90. The light source unit 10 is housed inside the main body 90 with the light-emitting surface of the LED module facing the bottom surface of the main body 90. The control unit 11 is housed inside the main body 90 between the light source unit 10 and the inner bottom surface of the main body 90.

[0038] The cover 91 is formed in a rectangular plate shape from a translucent synthetic resin such as acrylic resin or polycarbonate resin. The cover 91 is configured to diffuse the light emitted from the light source unit 10. Specifically, the synthetic resin forming the cover 91 is filled with a light-diffusing filler, thereby imparting light diffusion properties to the cover 91. The light emitted from the light source unit 10 (LED module) enters the cover 91 from the inner surface (top surface) of the cover 91, is diffused by the filler, and is emitted to the outside of the cover 91 from the outer surface (bottom surface) of the cover 91.

[0039] Each of the pair of panels 92 is formed into a rectangular plate shape using a translucent synthetic resin such as acrylic resin or polycarbonate resin. One of the pair of panels 92 is attached to each end of the main body 90 in the short direction. One longitudinal end of each panel 92 enters the main body 90 from the open end (bottom end) of the main body 90 and faces some of the LEDs in the light source unit 10 (LED module). Each panel 92 is configured to capture light emitted from some of the LEDs from the end that enters the main body 90 and guide the captured light to emit it, thereby causing the entire panel 92 to emit light. In other words, the lighting device 1 essentially has three light source units 10: a light source unit 10 that emits light through the cover 91 and a light source unit 10 that emits light from each of the pair of panels 92.

[0040] The pair of speaker units 93 are provided integrally with the main body 90, one at each end in the longitudinal direction of the main body 90. Each speaker unit 93 is, for example, an electrodynamic speaker unit. One speaker unit 93 outputs sound from the left channel of stereo playback, and the other speaker unit 93 outputs sound from the right channel of stereo playback.

[0041] The configuration of the lighting device 1 described above is an example, and one or more lighting devices having other configurations may be included in the lighting system S1.

[0042] (2-1-2) Terminal device The terminal device 2 is preferably a mobile device such as a smartphone. However, the terminal device 2 is not limited to a smartphone and may be a tablet, a notebook PC (Personal Computer), or a so-called smart TV. In the following description, a smartphone is used as the terminal device 2.

[0043] The terminal device 2 is equipped with a mobile device-oriented SoC (System on a chip). The mobile device-oriented SoC is configured by integrating a CPU (Central Processing Unit) 20, a GPU (Graphics Processing Unit), a memory, a communication circuit, various sensors, and the like into a single integrated circuit.

[0044] The terminal device 2 includes an analysis unit 201, a lighting control unit 202, a determination unit 203, a detection unit 21, a presentation unit 22, a notification unit 23, an input reception unit 24, a storage unit 25, a communication unit 26, and the like (see FIG. 1).

[0045] The presentation unit 22 and the notification unit 23 include a display (liquid crystal display or organic EL display) mounted on the terminal device 2 (smartphone). However, the presentation unit 22 and the notification unit 23 may include a speaker mounted on the terminal device 2 in addition to the display.

[0046] The presentation unit 22 and the notification unit 23 are configured to present and notify various pieces of information to the subject H1 by displaying visual information such as characters, figures, and images on the display.

[0047] The input receiving unit 24 includes a touch panel mounted on the terminal device 2 (smartphone). The touch panel is configured integrally with the display of the terminal device 2. When icons and buttons displayed on the display are touched, the input receiving unit 24 receives operation inputs corresponding to the icons and buttons. The operation inputs received by the input receiving unit 24 are input to the CPU 20 of the terminal device 2.

[0048] The communication unit 26 is configured to perform wireless communication in accordance with communication standards such as Wi-Fi (registered trademark) and / or BLE (Bluetooth (registered trademark) low energy). The communication unit 26 can also perform wireless communication in accordance with standards for mobile communication systems provided by telecommunications carriers.

[0049] The detection unit 21 includes a camera mounted on the terminal device 2 (smartphone). The camera of the detection unit 21 includes an imaging element such as a CMOS image sensor or a CCD image sensor, and a lens for focusing light on the light receiving surface of the imaging element. The detection unit 21 also includes an image processing circuit that performs image processing on an image captured by the camera. The image processing circuit performs so-called markerless motion capture measurement on the image captured by the camera (e.g., an image capturing the entire body of the subject H1 while exercising), and detects skeletal information of the subject H1 (the state of the subject H1) based on the measurement results of the motion capture measurement, for example, using machine learning. The motion capture measurement process and skeletal information detection process in the detection unit 21 can be executed by the CPU 20 of the smartphone, for example.

[0050] The analysis unit 201, the lighting control unit 202, and the determination unit 203 are realized by executing an application program for lighting control (hereinafter abbreviated as lighting control app), which corresponds to the program according to the embodiment, on the CPU 20 of the SoC.

[0051] The analysis unit 201 analyzes the exercise performed by the subject H1 based on the state of the subject H1 (skeletal information of the subject H1) detected by the detection unit 21. Specifically, the analysis unit 201 analyzes the skeletal information of the subject H1 detected by the detection unit 21 to determine the accuracy of the exercise performed by the subject H1, the number of times the exercise has been completed, and the like. For example, one type of core training is an exercise called the plank. The plank is a core training in which the subject lies face down with their forearms, elbows, and toes on the floor and maintains this position for a certain period of time (see FIG. 3). Note that core training is an exercise for strengthening the trunk (the body part excluding the neck, upper body, arms, and legs).

[0052] When subject H1 performs the plank, he needs to keep his head, upper body, and lower body aligned in a straight line; for example, if his upper and lower body are bent in a dogleg shape, it will not be effective (correct) core training.

[0053] Therefore, the analysis unit 201 determines the angles of the head, upper body, and lower body of the subject H1 by analyzing the skeletal information of the subject H1. For example, if the angle between the upper body and lower body is within a range of 0±2°, the analysis unit 201 determines the accuracy of the exercise (plank) as 5 (most accurate) on a 5-point scale, and as the angle between the upper body and lower body increases, the analysis unit 201 determines the numerical value of the 5-point scale as 4, 3, 2, and 1.

[0054] Furthermore, when subject H1 performs squats, the analysis unit 201 detects the posture of subject H1 from the skeletal information of subject H1 and determines the number of times that subject H1 was able to bend and straighten his / her knees in the correct posture (the number of squats achieved).

[0055] The analysis unit 201 sends the above-mentioned analysis results, for example, the accuracy of the exercise (the value of the plank on a five-point scale), the number of times achieved (the number of times the squat was achieved), and the like, to the lighting control unit 202.

[0056] The lighting control unit 202 controls the control unit 11 to change the light output of the light source unit 10 based on the analysis result of the exercise of the subject H1 by the analysis unit 201. For example, the lighting control unit 202 controls the control unit 11 to adjust the light color (color temperature) to correspond to the accuracy of the exercise performed by the subject H1 (the numerical value on a five-point scale of Planck's scale). Alternatively, the lighting control unit 202 controls the control unit 11 to blink or dim the light source unit 10 a number of times corresponding to the number of exercises performed by the subject H1 (the number of squats completed).

[0057] The lighting control patterns described above are stored in advance in storage unit 25. Storage unit 25 has an electrically rewritable non-volatile semiconductor memory and / or a memory card. Storage unit 25 stores a plurality of lighting control patterns, including the lighting control patterns described above. Lighting control unit 202 then reads out from storage unit 25 the lighting control pattern corresponding to the analysis result of analysis unit 201, and causes communication unit 26 to transmit data of the read lighting control pattern to lighting device 1.

[0058] The determination unit 203 determines the exercise load of the exercise to be performed by the subject H1. In this embodiment, the exercise load is the load that the exercise places on the body of the subject H1, in other words, the intensity of the exercise, and is indicated, for example, by three levels: strong, medium, and weak. The determination unit 203 determines the exercise load appropriate for the subject H1 based on the subject information (such as the age, sex, height, and weight of the subject H1) received by the input receiving unit 24. Furthermore, it is preferable that the determination unit 203 lowers the exercise load based on a change in the condition of the subject H1, for example, a decrease in the accuracy of the exercise or a decrease in the number of times the exercise is completed. Alternatively, the determination unit 203 may increase the exercise load if the accuracy of the exercise is high or the number of times the exercise is completed is sufficiently high.

[0059] (2-2) Operation of the lighting system according to the embodiment Next, the operation of the lighting system S1 will be described. In the following description, it is assumed that a subject H1, who is a resident, is exercising in a living room R1 of a house while taking a self-image with the camera of the terminal device 2 (see FIG. 3). However, the lighting device 1 is installed on the ceiling X1 of the living room R1. In addition, the terminal device 2 is placed on the floor X3 so that the whole body of the subject H1 can be photographed from the left side.

[0060] First, the subject H1 launches a lighting control app installed on the terminal device 2 (smartphone). The lighting control app is an application program for lighting control, which corresponds to the program according to the embodiment, and is executed by the CPU 20 of the terminal device 2. That is, the analysis unit 201, lighting control unit 202, and determination unit 203 of the terminal device 2 are realized by the lighting control app.

[0061] The lighting control app first displays a login screen (login screen) on the display of the terminal device 2. When a login ID and password are entered on the login screen, the lighting control app performs user authentication using the entered login ID and password. Note that, as will be described later, a server that distributes exercise videos may also perform user authentication. The server can communicate bidirectionally with the communication unit 26 of the terminal device 2 via a wide area communication network such as the Internet.

[0062] After user authentication is complete, the lighting control app displays a menu screen G1 on the presentation unit 22 (display) of the terminal device 2 (see FIG. 4). In the menu screen G1 shown in FIG. 4, "living room" is selected as the installation location of the lighting device 1, and "exercise" is selected from among multiple items (yoga, exercise, meditation, and record) selectable in "living room." Furthermore, the menu screen G1 displays multiple buttons B1 to which multiple courses included in "exercise" are assigned in a one-to-one correspondence. Note that a thumbnail image of a video corresponding to the course of each button B1 is displayed on the left side of each button B1.

[0063] When the lighting control app receives an operation input indicating that one of the buttons B1 has been touched through the input receiving unit 24, it determines that the course assigned to the touched button B1 has been selected. The lighting control app creates a control command requesting the delivery of a video (a video of a person exercising) corresponding to the selected course, and transmits a packet including the created control command from the communication unit 26 to the server. For example, when the subject H1 touches the fourth button B1 from the top, the lighting control app transmits a packet including a control command corresponding to the "core training" (plank) course assigned to the fourth button B1 from the communication unit 26 to the server.

[0064] The server receives the packet transmitted from the communication unit 26 of the terminal device 2. In accordance with the control command contained in the received packet, the server reads out video data corresponding to the "core training" (plank) course from video data stored in a non-transitory storage medium such as a hard disk.

[0065] On the other hand, the lighting control app transmits a packet including a control command corresponding to the "core training" (plank) course to the server, and then displays a playback screen G2 for playing (streaming) video data on the screen of the presentation unit 22 (display) (see FIG. 5). When the playback screen G2 is touched, the lighting control app transmits a packet including a command requesting streaming of the video data from the communication unit 26 to the server.

[0066] When the server receives a packet including a command requesting streaming of video data, it streams the video data to terminal device 2 in accordance with the command included in the packet. The lighting control app receives the video streamed from the server via communication unit 26 and displays the received video on the display of presentation unit 22 (see FIG. 5 ). However, the server may also distribute audio data including music, etc., to terminal device 2 along with the video data. The lighting control app outputs sound (such as music) corresponding to the audio data streamed from the server from the speaker of terminal device 2. However, the lighting control app may also transfer the audio data to wireless communication unit 13 of lighting device 1 and play it on sound playback unit 12 of lighting device 1.

[0067] Then, the subject H1 places the terminal device 2 on the floor X3 of the living room R1 and performs exercise (plank) (see FIG. 3). The lighting control app causes the detection unit 21, the analysis unit 201, and the lighting control unit 202 to execute the processes that they are responsible for (see steps ST1 to ST3 in the flowchart of FIG. 6).

[0068] The detection unit 21 detects the state (skeletal information) of the subject H1 during exercise (see step ST1 in the flowchart of FIG. 6). The analysis unit 201 analyzes the skeletal information of the subject H1 to determine the angles of the head, upper body, and lower body of the subject H1, and evaluates the accuracy of the exercise (plank) on a five-point scale (see step ST2 in the flowchart of FIG. 6).

[0069] The lighting control unit 202 reads out a lighting control pattern corresponding to the analysis result of the movement of the subject H1 by the analysis unit 201 (for example, the numerical value of the Planck's five-point scale) from the storage unit 25. Then, the lighting control unit 202 causes the communication unit 26 to transmit a packet including data of the lighting control pattern read out from the storage unit 25 to the lighting device 1 (see step ST3 in the flowchart of FIG. 6).

[0070] The wireless communication unit 13 of the lighting device 1 receives the packet transmitted from the communication unit 26 of the terminal device 2, and sends the lighting control pattern data contained in the received packet to the control unit 11. Based on the lighting control pattern data received from the wireless communication unit 13, the control unit 11 controls the light source unit 10 so that the light output emitted from the light source unit 10 matches the lighting control pattern.

[0071] When the subject H1 wants to stop or finish exercising, he or she touches the playback screen G2 to stop the playback of the video. The lighting control app determines whether the subject H1 has finished exercising based on whether the video is being played back (see step ST4 in the flowchart of FIG. 6). If the video playback has not stopped, the lighting control app continues to have the detection unit 21 detect the state of the subject H1. On the other hand, if the video playback has stopped, the lighting control app determines that the subject H1 has stopped or finished exercising, and ends the lighting control process.

[0072] Here, the subject H1 who is exercising may not be able to see the display of the terminal device 2. For example, when the subject H1 is doing planks, the terminal device 2 is placed to the left (or right) side of the subject H1 so that the whole body of the subject H1 can be imaged by the camera, and it is therefore difficult for the subject H1 who is exercising to see the display screen of the terminal device 2 (see FIG. 3). Therefore, it is difficult to inform the subject H1 who is exercising of the analysis results by simply displaying the analysis results of the analysis unit 201 on the display of the terminal device 2.

[0073] In response to this, the lighting system S1 causes the lighting control unit 202 to control the control unit 11 so that the light output of the light source unit 10 matches the lighting control pattern corresponding to the analysis result of the analysis unit 201. Then, the lighting system S1 changes the lighting environment of the living room R1 in accordance with the lighting control pattern, thereby making it possible to inform the subject H1 who is exercising of the analysis result of the exercise (such as the numerical value of the five-point Planck evaluation).

[0074] For example, when the subject H1 is doing a plank, the analysis unit 201 determines the direction (leftward, rightward, etc.) in which the subject H1's body is misaligned based on the skeletal information of the subject H1 detected by the detection unit 21. Then, the lighting control unit 202 may change at least one of the light intensity and light color of the light source unit 10 according to the direction in which the body is misaligned so as to inform the subject H1 of the direction in which the body is misaligned.

[0075] Therefore, the lighting system S1 causes the lighting control unit 202 to control the control unit 11 to change the light output of the light source unit 10 based on the analysis results of the movement of the subject H1 by the analysis unit 201, thereby realizing a lighting environment that is beneficial to the awake person (subject H1).

[0076] Furthermore, the lighting system S1 has the lighting control unit 202 control the control unit 11 to change either or both of the light intensity and light color of the light source unit 10 based on the analysis results, which has the advantage of making it easier to inform the subject H1 of the analysis results of the exercise.

[0077] Furthermore, the lighting system S1 includes a presentation unit 22 in the terminal device 2 that presents the exercise content of the subject H1 to the subject H1 (see FIG. 1). The presentation unit 22 presents the exercise content to the subject H1 through moving images or still images (see FIGS. 4 and 5). That is, the subject H1 can perform the exercise more accurately using the moving images or still images (thumbnail images) presented on the presentation unit 22. The presentation unit 22 may present the exercise content to the subject H1 through sound (e.g., voice) output from the speaker of the terminal device 2 or the sound reproduction unit 12 of the lighting device 1, together with the moving images or still images, or instead of at least one of the moving images and still images.

[0078] Thus, the lighting system S1 causes the presentation unit 22 to present the exercise content of the subject H1 to the subject H1 through at least one medium of moving images, still images, and sound, thereby helping the subject H1 to exercise correctly.

[0079] Incidentally, the lighting system S1 may notify the subject H1 of the analysis result, in addition to the change in the lighting environment, through at least one medium of a moving image, a still image, or sound from the notification unit 23 of the terminal device 2. Since the notification unit 23 includes a display of the terminal device 2, it can notify the subject H1 of the analysis result by displaying visual information such as characters, figures, and images on the display, or by sound output from a speaker, etc.

[0080] Thus, the lighting system S1 causes the notification unit 23 to notify the analysis result through at least one medium of a moving image, a still image, and sound, so that the analysis result can be made known to the subject H1 in a manner that is easier to understand.

[0081] Furthermore, the lighting system S1 has the lighting device 1 including the light source unit 10 installed on the ceiling X1 of the room (living room R1) where the subject H1 exercises, which has the advantage that the light source unit 10 can be used as general lighting when the subject H1 is not exercising. Note that the light source unit 10 (or a lighting device including the light source unit 10) may also be installed on the wall X2 of the room (living room R1).

[0082] The lighting device 1 essentially has three light source units 10, namely, a light source unit 10 that emits light through the cover 91 and a light source unit 10 that emits light from each of the pair of panels 92. Therefore, the lighting system S1 may have the lighting control unit 202 control the control unit 11 to change the light output of each of the three light source units 10 using different lighting control patterns. For example, the lighting control unit 202 may control the control unit 11 to turn on the light source unit 10 that emits light through the cover 91 in a steady state and turn on the light source units 10 that emit light from the pair of panels 92 using a lighting control pattern corresponding to the analysis results. Alternatively, the lighting control unit 202 may control the control unit 11 to turn on the light source unit 10 that emits light through the cover 91 using a lighting control pattern corresponding to the accuracy of the exercise and turn on the light source units 10 that emit light from the pair of panels 92 using a lighting control pattern corresponding to the number of exercises completed.

[0083] Therefore, the lighting system S1 causes the lighting control unit 202 to control the control unit 11 so as to change the light output of each of the multiple light source units 10 in a different pattern, making it easier for the subject H1 to recognize the analysis results from changes in the lighting environment.

[0084] (2-3) Details of the lighting control method according to the embodiment A lighting control method according to an embodiment (hereinafter simply referred to as the lighting control method) controls the lighting environment of a location where a subject H1 is exercising. Specifically, the lighting control method is realized by executing the following steps ST1-ST3 in the lighting system S1 described above.

[0085] That is, the lighting control method includes step ST1 of detecting the state of the exercising subject H1, step ST2 of analyzing the exercise performed by the subject H1 based on the state of the subject H1 detected in step ST1, and step ST3 of changing the light output of the light source unit 10 based on the analysis result of the exercise (see FIG. 6). Note that, according to the lighting control method, the subject H1 can recognize the accuracy of his / her exercise, the number of times he / she has achieved, etc. from changes in the surrounding brightness (lighting environment) without looking directly at the light source unit 10.

[0086] Thus, the lighting control method changes the light output of the light source unit 10 based on the analysis result of the movement performed by the subject H1, and therefore can realize a lighting environment that is beneficial to the awake person (subject H1).

[0087] (2-4) Details of the program according to the embodiment The program according to the embodiment is a program that causes a computer (the CPU 20 of the terminal device 2) to execute the following steps ST1 to ST3, that is, a lighting control application that is executed by the CPU 20 of the terminal device 2.

[0088] The program (lighting control application) according to the embodiment includes step ST1 of causing the detection unit 21 to detect the state of the exercising subject H1, step ST2 of causing the analysis unit 201 to analyze the exercise performed by the subject H1 based on the state of the subject H1, and step ST3 of causing the lighting control unit 202 to control the control unit 11 to change the light output of the light source unit 10 based on the analysis result of the exercise. That is, by causing a computer to execute the program according to the embodiment, the subject H1 can recognize the accuracy of his / her exercise, the number of times he / she has completed, and the like from changes in the surrounding brightness (lighting environment) without looking directly at the light source unit 10.

[0089] Therefore, the program according to the embodiment changes the light output of the light source unit 10 based on the analysis result of the exercise performed by the subject H1, and therefore, it is possible to realize a lighting environment that is beneficial to an awake person (subject H1).

[0090] (3) Modifications of the lighting system according to the embodiment Next, several modified examples of the lighting system S1 according to the embodiment will be described. However, the basic configuration of the lighting system S1 of each modified example described below is common to the basic configuration of the lighting system S1 according to the embodiment described above. Therefore, in the lighting system S1 of each modified example, illustrations and descriptions of configurations that are substantially common to the basic configuration of the lighting system S1 according to the embodiment will be omitted as appropriate. In the following description, "substantially common configuration" means a configuration that is slightly different in shape, size, etc. but has the same function.

[0091] (3-1) Variation 1 The lighting system S1 of the first modification includes a plurality of detectors 21. The plurality of detectors 21 in the first modification include a camera mounted on the terminal device 2 as well as various sensors mounted on a wearable terminal worn on the body of the subject H1. The wearable terminal is a smart watch worn on the wrist of the subject H1, a smart ring worn on the finger of the subject H1, or the like. These wearable terminals include a plurality of types of sensors, such as a pulse sensor, a respiration sensor, a blood pressure sensor, a body temperature sensor, an angular acceleration sensor (gyro sensor), and an acceleration sensor. The wearable terminal is configured to transmit the measurement values ​​of each sensor to the terminal device 2 (smartphone) by performing short-range wireless communication with the terminal device 2.

[0092] The analysis unit 201 in the first modification determines the accuracy of the exercise and the number of times it has been completed based on the skeletal information of the subject H1 detected by the detection unit 21, as in the embodiment. The analysis unit 201 in the first modification also determines the pulse rate, respiratory rate, blood pressure, body temperature, etc. of the subject H1 by analyzing the measured values ​​of each sensor in the wearable device. Furthermore, the analysis unit 201 in the first modification evaluates the inclination of the subject H1's body by analyzing the measured values ​​of the angular acceleration sensor and acceleration sensor.

[0093] The lighting control unit 202 in Modification 1 controls the control unit 11 to change the light output of the plurality of light source units 10 in different lighting control patterns based on the analysis results of the analysis unit 201. For example, the lighting control unit 202 in Modification 1 controls the control unit 11 to change the light output of the light source units 10 that emit light through the cover 91 in a lighting control pattern corresponding to the accuracy of the exercise, and controls the control unit 11 to change the light output of the light source units 10 that emit light from one of the panels 92 in a lighting control pattern corresponding to the number of exercises completed. Furthermore, the lighting control unit 202 in Modification 1 controls the control unit 11 to change the light output of the light source units 10 that emit light from the other panel 92 in a lighting control pattern corresponding to values ​​(vital signs) such as the pulse rate, respiratory rate, blood pressure, and body temperature of the subject H1, or a lighting control pattern corresponding to the body tilt of the subject H1.

[0094] Thus, the lighting system S1 of the first modification causes the lighting control unit 202 to control the control unit 11 to change the light output of each of the plurality of light source units 10 in a different lighting control pattern based on the analysis results by the analysis unit 201 for each of the plurality of detection units 21 as described above. As a result, the lighting system S1 of the first modification can easily notify the subject H1 of multiple types of analysis results regarding the movement of the subject H1.

[0095] (3-2) Variation 2 The lighting system S1 of the second modification is characterized in that the lighting control unit 202 controls the control unit 11 to change the light output of the light source unit 10 using a lighting control pattern corresponding to information about the exercise of the subject H1. Here, the information about the exercise of the subject H1 includes, for example, information about the pace of the exercise, the timing to switch the type of exercise, and the remaining time of the exercise. For example, if the subject H1 is doing squats, the pace of the exercise refers to the number of squats per minute. Furthermore, if the exercise course includes a combination of multiple types of exercise, the timing to switch the type of exercise refers to the timing to end one type of exercise and start another type of exercise. Furthermore, the remaining time of the exercise refers to the remaining time remaining after subtracting the time the subject H1 actually performed that exercise from the required time set for each type of exercise (the time to perform the same exercise continuously).

[0096] The lighting control unit 202 in Modification 2 controls the control unit 11 to change the light output of the light source unit 10 in a lighting control pattern corresponding to the information related to the exercise of the subject H1 as described above. For example, the lighting control unit 202 in Modification 2 controls the control unit 11 to gradually increase or decrease (fade in / fade out) the light output of the light source unit 10 in accordance with the pace of the exercise. Furthermore, the lighting control unit 202 in Modification 2 controls the control unit 11 to increase or decrease (blink) the light output of the light source unit 10 in short cycles in accordance with the timing of switching the type of exercise. Furthermore, the lighting control unit 202 in Modification 2 controls the control unit 11 to decrease the light output of the light source unit 10 in accordance with the remaining time of the exercise.

[0097] Therefore, the lighting system S1 of variant example 2 causes the lighting control unit 202 to control the control unit 11 so as to change the light output of the light source unit 10 in a lighting control pattern corresponding to information regarding the exercise of the subject H1, thereby making it possible to easily inform the subject H1 of information regarding the exercise.

[0098] In addition, the lighting system S1 of variant example 2 may have the presentation unit 22 present information regarding the movement of the subject H1 described above through at least one medium of moving images, still images, and sound, in addition to changes in the light output of the light source unit 10.

[0099] Therefore, the lighting system S1 of variant example 2 causes the presentation unit 22 to present information regarding the exercise of the subject H1 through at least one medium of moving images, still images, and sound, making it easier for the subject H1 to be informed of information regarding exercise.

[0100] (3-3) Variation 3 The lighting system S1 of the third modification is characterized in that the input of subject information about the subject H1 is received by the input receiving unit 24, and the determination unit 203 determines an exercise load suitable for the subject H1 based on the subject information received by the input receiving unit 24. Here, the subject information about the subject H1 includes, for example, age, sex, height, weight, body fat percentage, body mass index (BMI), etc.

[0101] The input accepting unit 24 in the third modification displays an input accepting screen on the display of the terminal device 2 and accepts input of the subject information based on a touch operation by the subject H1. However, if the subject information is stored in the memory of the smartphone (terminal device 2) owned by the subject H1, the input accepting unit 24 in the third modification may accept the subject information read out from the memory.

[0102] The determination unit 203 in the third modification determines an exercise load suitable for the subject H1 based on the subject information received by the input receiving unit 24. Here, the exercise load suitable for the subject H1 is the load that exercise places on the body of the subject H1, in other words, the intensity of the exercise. Exercise intensity is generally expressed in "METs (Met-Exercises)," "heart rate," etc. METs indicate the intensity of an activity by how many times more energy is consumed compared to when the energy consumed at rest is set to 1.

[0103] Furthermore, because heart rate increases linearly during exercise in almost proportion to oxygen intake, heart rate can be used to represent exercise intensity. Exercise intensity (exercise load) can be calculated from heart rate using, for example, the Karvonen method, which uses age and resting heart rate. The Karvonen method can be calculated using {(220 ​​- age) - resting heart rate} x exercise intensity (%) + resting heart rate.

[0104] For example, if subject H1 is 50 years old, has a resting heart rate of 60 beats / min, and is exercising at 50% intensity, then {(220-50)-60 beats / min)} x 50% + 60 beats / min = 115 beats / min. In this case, if subject H1's heart rate rises to 115 beats / min during exercise, then the exercise is at 50% intensity; if the heart rate does not rise to 115 beats / min, the exercise intensity needs to be higher (stronger) than 50%.

[0105] In the lighting system S1 of the third modification, the exercise load (exercise intensity) is displayed in three levels: strong, medium, and weak, to make it easier for the subject H1 to understand. For example, an exercise intensity of 60% or more is a strong level, an exercise intensity of 40% to less than 60% is a medium level, and an exercise intensity of less than 40% is a weak level. However, the relationship between these levels and the exercise load (exercise intensity) is merely an example. Indicators of exercise load are not limited to heart rate and METs.

[0106] Here, on the menu screen G1 displayed on the presentation unit 22 (display) by the lighting control app, the exercise load (exercise intensity) and standard exercise time for each course are displayed in the area of ​​a plurality of buttons B1 assigned one-to-one to a plurality of exercise courses. For example, the "Aerobic Exercise Beginner" course has a low exercise load (one star) and an exercise time of 11 minutes. The "Aerobic Exercise Advanced" course has a high exercise load (three stars) and an exercise time of 12 minutes. Furthermore, the "Core Training" (Plank) course has a medium exercise load (two stars) and an exercise time of 15 minutes.

[0107] For example, the determination unit 203 in Modification 3 determines an exercise (exercise course) with a high exercise load if the subject H1 is male and in his 30s or younger. Furthermore, the determination unit 203 in Modification 3 determines an exercise (exercise course) with a medium exercise load if the subject H1 is male and in his 40s to 50s, or female and in his 30s or younger. Furthermore, the determination unit 203 in Modification 3 determines an exercise (exercise course) with a low exercise load if the subject H1 is male and in his 60s or older, or female and in his 40s or older. However, the rules by which the determination unit 203 in Modification 3 determines an exercise suitable for the subject H1 are not limited to the above-described rules.

[0108] The presentation unit 22 in the third modification presents to the subject H1 the button B1 corresponding to the exercise content (exercise course) determined by the determination unit 203 in the third modification by highlighting or blinking the button B1. Therefore, the subject H1 can easily select the recommended exercise content (exercise course) based on his / her age, sex, etc.

[0109] Therefore, the lighting system S1 of variant example 3 has the determination unit 203 determine the exercise load appropriate for the subject H1 based on the subject information received by the input receiving unit 24, thereby improving usability compared to when the subject H1 is allowed to determine the exercise load.

[0110] Furthermore, the determination unit 203 in Modification 3 may change (determine) the exercise load based on a change in the condition of the subject H1. For example, if the heart rate of the subject H1 detected by the detection unit 21 in Modification 3 is lower than a reference value of the heart rate corresponding to the exercise load (exercise intensity) of the exercise being performed by the subject H1, it is preferable that the determination unit 203 in Modification 3 increase the exercise load. Alternatively, if the heart rate of the subject H1 detected by the detection unit 21 in Modification 3 is higher than a reference value of the heart rate corresponding to the exercise load (exercise intensity) of the exercise being performed by the subject H1, it is preferable that the determination unit 203 in Modification 3 decrease the exercise load.

[0111] Thus, the lighting system S1 of the third modification can suggest exercise with a more appropriate exercise load to the subject H1 by having the determination unit 203 determine an exercise load suitable for the subject H1 based on a change in the state of the subject H1.

[0112] In addition, the lighting system S1 of variant example 3 may have the analysis unit 201 analyze changes in the condition of the subject H1 before, during, or after exercise, and the lighting control unit 202 control the control unit 11 to change the light output of the light source unit 10 in accordance with the changes in the condition of the subject H1.

[0113] The analysis unit 201 in the third modification analyzes the state of the subject H1 before, during, or after exercise, detected by the detection unit 21, for example, changes in the posture of the subject H1 based on skeletal information, heart rate, etc. If a significant difference is found in the state of the subject H1 before, during, or after exercise, the analysis unit 201 in the third modification causes the illumination control unit 202 to control the control unit 11 to change the light output of the light source unit 10 in accordance with the change in the state of the subject H1, based on the difference in the state of the subject H1 (for example, a difference in heart rate).

[0114] Therefore, the lighting system S1 of variant example 3 causes the lighting control unit 202 to control the control unit 11 to change the light output of the light source unit 10 in accordance with changes in the condition of the subject H1 before, during, or after exercise, thereby making it possible to notify the subject H1 of changes in the condition of the subject H1.

[0115] However, the lighting system S1 of the third modification may have the presentation unit 22 present the change in the state of the subject H1 through at least one of a moving image, a still image, and sound in addition to the light output of the light source unit 10.

[0116] Therefore, the lighting system S1 of variant example 3 causes the presentation unit 22 to present changes in the condition of the subject H1 through at least one of moving images, still images, and sound, thereby making it possible to more clearly inform the subject H1 of changes in the condition of the subject H1.

[0117] (3-4) Variation 4 The lighting system S1 of the fourth modification includes a plurality of detectors 21, similar to the first modification. The plurality of detectors 21 in the fourth modification include a camera mounted on the terminal device 2, as well as various sensors mounted on a wearable terminal worn on the body of the subject H1 to measure the subject H1's vital signs (pulse, respiration, body temperature, blood pressure, etc.). The wearable terminal is a smart watch worn on the wrist of the subject H1, a smart ring worn on the finger of the subject H1, or the like. The wearable terminal is configured to transmit the measurement values ​​(vital signs) of each sensor to the terminal device 2 (smartphone) by performing short-range wireless communication with the terminal device 2.

[0118] The lighting system S1 of the fourth modification is characterized in that the determination unit 203 determines an exercise load suitable for the subject H1 based on the vital signs detected by the detection unit 21. The analysis unit 201 in the fourth modification estimates the physical condition of the subject H1 by analyzing the vital signs of the subject H1 detected by the detection unit 21. For example, if the analysis result of the analysis unit 201 in the fourth modification indicates that the maximum value of the resting blood pressure detected by the detection unit 21 is 110 mm / Hg or more or the minimum value is 70 mm / Hg or less, the determination unit 203 in the fourth modification determines that the physical condition of the subject H1 is not good and determines a relatively low exercise load (weak level exercise load). However, if the determination unit 203 in the fourth modification determines that the physical condition of the subject H1 is not good, it may decide to stop the exercise. Note that the determination unit 203 may determine the physical condition of the subject H1 based on the analysis results of vital signs other than blood pressure or multiple types of vital signs including blood pressure.

[0119] The lighting system S1 of variant example 4 causes the presentation unit 22 to present the content of the exercise or the cessation of the exercise determined by the determination unit 203 through a change in the light output of the light source unit 10 or a combination of a change in the light output of the light source unit 10 and at least one of a moving image, a still image, and sound.

[0120] Therefore, the lighting system S1 of variant example 4 has the determination unit 203 determine an exercise load suitable for the subject H1 based on the vital signs detected by the detection unit 21, so that an appropriate exercise load can be determined in accordance with the physical condition of the subject H1.

[0121] (3-5) Variation 5 The lighting system S1 of the fifth modification is characterized in that the storage unit 25 stores history information including the exercise performed by the subject H1 and the analysis results.

[0122] The storage unit 25 in the fifth modification stores the exercise performed by the subject H1 (such as the exercise content, exercise course, and exercise time) with a date. The storage unit 25 in the fifth modification also stores the analysis results of the exercise performed by the subject H1 by the analysis unit 201. The lighting system S1 in the fifth modification may read out the information stored in the storage unit 25 in the fifth modification (information on the exercise performed by the subject H1 and the analysis results of the exercise) and display it on the display unit 22 (see FIG. 7). FIG. 7 shows a screen G3 on which the display unit 22 displays the information stored in the storage unit 25. This screen G3 displays the exercise information of the subject H1, such as the number of times the subject H1 has performed the same exercise in a month.

[0123] Therefore, the lighting system S1 of variant example 5 stores historical information including the exercise performed by the subject H1 and the analysis results in the memory unit 25, so that historical information of past exercise can be presented to the subject H1, thereby improving usability.

[0124] (3-6) Variation 6 The lighting system S1 of the sixth modification is provided with a lighting device 1 and a fan 14 (see FIGS. 8 and 9). The fan 14 has a main body 140 attached to the ceiling and four blades 141 rotatably provided at the bottom of the main body 140 (see FIG. 9). A motor for rotating the blades 141 is built into the main body 140.

[0125] Four LED lamps 30 are attached to the bottom of the main body 140. Each LED lamp 30 is equipped with a light source unit 10. The control unit 11, sound reproduction unit 12, and wireless communication unit 13 are housed inside the main body 140. However, one control unit 11 may be provided for each LED lamp 30. The control unit 11 controls the blower 14 to blow air into the illumination area according to the lighting control pattern. The blower 14 does not need to be integrated with the lighting device 1, and may be a standalone device with the function of blowing air, such as an electric fan or air conditioner.

[0126] Therefore, the lighting system S1 of variant example 6 can send air from the blower 14 in accordance with the lighting control pattern, thereby providing information such as the analysis results of the exercise or the timing of switching exercises to the subject H1 exercising within the illumination range of the lighting light (living room R1).

[0127] (3-7) Variation 7 The lighting system S1 of the seventh modification includes a diffuser 15 that diffuses a scent in an illuminated area (see FIG. 10). The diffuser 15 is generally a device that atomizes and diffuses aromatic oil.

[0128] Control unit 11 controls diffuser 15 to diffuse the fragrance in the illumination area according to the lighting control pattern. Note that diffuser 15 does not need to be integrated with lighting device 1, and may be, for example, a standalone device as a diffuser.

[0129] Therefore, the lighting system S1 of variant example 7 can diffuse fragrance from the diffuser 15 in accordance with the lighting control pattern, thereby providing information such as the analysis results of the exercise or the timing of switching exercise to the subject H1 exercising within the illumination range of the lighting light (living room R1).

[0130] (4) Summary A lighting system (S1) according to a first aspect of the present disclosure includes one or more light source units (10), a control unit (11) that controls the light source units (10), a detection unit (21) that detects the state of an exercising subject (H1), an analysis unit (201), and a lighting control unit (202).
