DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, a lighting system, a lighting device, a lighting control method, and a program according to embodiments of the present disclosure will be described in detail with reference to the drawings. However, each diagram described in the following embodiments is a schematic diagram, 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 1, a control unit 3 that controls the light source units 1, a lighting control unit 2 that controls the control unit 3, and a display unit 4 that displays moving images (see FIG. 1).

[0015] At least one of the light intensity and light color of the light source unit 1 is variable. For example, the light source unit 1 has multiple types of LEDs (Light Emitting Diodes) that emit light of different colors. However, the light source unit 1 may also have light-emitting elements other than LEDs, such as organic EL (Electro Luminescence) elements or laser diodes.

[0016] The control unit 3 controls the light source unit 1 to change at least one of the light intensity and light color of the light source unit 1. The control unit 3 can change the light intensity and light color by increasing or decreasing the current supplied to the light source unit 1.

[0017] The display unit 4 includes, for example, a display device such as a liquid crystal display or an organic EL display, a driver circuit that drives the display device to display moving images, still images, characters, symbols, and the like, and the like.

[0018] The lighting control unit 2 controls the control unit 3 to change at least one of the light intensity and light color in conjunction with the video displayed on the display unit 4. For example, when a video of physical exercise (such as exercise or yoga) is displayed on the display unit 4, the lighting control unit 2 controls the control unit 3 to increase the light intensity as the intensity of the physical exercise performed in the video increases and to decrease the light intensity as the intensity of the physical exercise decreases. Alternatively, the lighting control unit 2 controls the control unit 3 to increase the light color (color temperature) as the physical exercise speed increases and to decrease the light color (color temperature) as the physical exercise speed decreases. However, the lighting control unit 2 may increase or decrease the light intensity (dimming) according to the intensity of the physical exercise and adjust the light color (color temperature) according to the speed of the physical exercise.

[0019] Therefore, the lighting system S1 according to the embodiment has the lighting control unit 2 control the control unit 3 to change at least one of the light intensity and light color in conjunction with the video displayed on the display unit 4, which has the advantage of promoting utilization of the lighting control function compared to, for example, a case where the light intensity and color are simply adjusted by the user's operation.

[0020] (1-2) Overview of the lighting device according to the embodiment An illumination device A1 according to the embodiment includes one or more light source units 1 and a control unit 3 that controls the light source units 1 (see FIG. 1).

[0021] At least one of the light intensity and light color of the light source unit 1 is variable. For example, the light source unit 1 has multiple types of LEDs that emit light of different colors. However, the light source unit 1 may also have light-emitting elements other than LEDs, such as organic EL elements or laser diodes.

[0022] Under the control of the lighting control unit 2, the control unit 3 controls the light source unit 1 to change at least one of the light intensity and the light color in conjunction with the video displayed on the display unit 4. For example, when a video of physical exercise (such as exercise or yoga) is displayed on the display unit 4, the control unit 3 controls the light source unit 1 to increase the light intensity as the intensity of the physical exercise performed in the video increases and to decrease the light intensity as the intensity of the physical exercise decreases. Alternatively, the control unit 3 controls the light source unit 1 to increase the light color (color temperature) as the physical exercise speed increases and to decrease the light color (color temperature) as the physical exercise speed decreases. However, the control unit 3 may increase or decrease the light intensity (dimming) according to the intensity of the physical exercise and adjust the light color (color temperature) according to the speed of the physical exercise.

[0023] Therefore, the lighting device A1 according to the embodiment has the control unit 3 control the light source unit 1 to change at least one of the light intensity and light color in conjunction with the video displayed on the display unit 4, which has the advantage of promoting utilization of the lighting control function compared to, for example, a case where the light intensity and color are simply adjusted by the user's operation.

[0024] (1-3) Overview of lighting control method according to embodiment The illumination control method according to the embodiment is a method for controlling a light source unit 1 in which at least one of the light intensity and light color is variable.

[0025] The illumination control method according to the embodiment controls the light source unit 1 so as to change at least one of the light intensity and the light color in conjunction with the moving image displayed on the display unit 4.

[0026] Therefore, the lighting control method according to the embodiment controls the light source unit 1 to change at least one of the light intensity and light color in conjunction with the video displayed on the display unit 4, and therefore has the advantage of promoting utilization of the lighting control function compared to, for example, a case where the light intensity and color are simply adjusted by the user's operation.

[0027] (1-4) Overview of the program according to the embodiment The program according to the embodiment is a so-called computer program that causes a computer system to execute the lighting control method according to the embodiment.

[0028] Therefore, the program according to the embodiment causes a computer system to execute the lighting control method according to the embodiment, which has the advantage of promoting utilization of the lighting control function compared to, for example, simply adjusting the brightness and color through user operation.

[0029] (2)Details (2-1) Details of the lighting system and lighting device according to the embodiment A lighting system S1 according to an embodiment (hereinafter simply referred to as lighting system S1) includes one or more light source units 1, a control unit 3 that controls the light source units 1, a lighting control unit 2 that controls the control unit 3, and a display unit 4 that displays moving images (see FIG. 1). The lighting system S1 also includes a server 6. The server 6 is capable of bidirectional communication with the lighting control units 2 and 3 via a wide area communication network (the Internet N1).

[0030] The display unit 4 includes a liquid crystal display or an organic EL display included in a communication terminal 7 (see FIG. 1 ), such as a smartphone, tablet, or laptop PC (Personal Computer). However, the display unit 4 may also be a television receiver equipped with a wireless LAN communication function. The communication terminal 7 performs bidirectional wireless communication with the lighting device A1 and the server 6 via a wireless router 8. The wireless router 8 is capable of bidirectional communication with the server 6 via the Internet N1. In other words, the communication terminal 7 can perform bidirectional communication with the server 6 via the Internet N1 by wirelessly communicating with the wireless router 8. However, if the distance between the communication terminal 7 and the lighting device A1 is short (e.g., a distance of several meters to several tens of meters), the communication terminal 7 may perform wireless communication directly with the lighting device A1 without using the wireless router 8. For example, the communication terminal 7 and the lighting device A1 may perform wireless communication in accordance with the BLE (Bluetooth (registered trademark) low energy) communication standard.

[0031] The communication terminal 7 is equipped with an SoC (System on a Chip) for mobile devices. The SoC for mobile devices is configured by integrating a processor, a GPU (Graphics Processing Unit), a memory, a communication circuit, various sensors, etc. into a single integrated circuit. The lighting control unit 2 is realized by executing an application program for lighting control (hereinafter abbreviated as a lighting control app), which corresponds to the program according to the embodiment, on the SoC processor.

[0032] An illumination device A1 according to this embodiment (hereinafter simply referred to as illumination device A1) includes, among the components of the illumination system S1, a light source unit 1 and a control unit 3 (see FIG. 1). The illumination device A1 further includes a sound reproduction unit 5.

[0033] The light source unit 1 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 1 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.

[0034] The control unit 3 has a lighting circuit that lights up the LED module of the light source unit 1, and a control circuit that controls the lighting circuit to increase or decrease the current supplied to the LED module.

[0035] 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 adjusting) the intensity and color (correlated color temperature) of the light emitted from the light source unit 1. The control circuit also has a communication function that enables wireless communication with the wireless router 8. That is, the control circuit (control unit 3) can use its communication function to communicate bidirectionally with the communication terminal 7 and the server 6 via the wireless router 8. However, the control circuit (control unit 3) may also communicate directly and bidirectionally with the communication terminal 7 by performing wireless communication conforming to a communication standard such as BLE (Bluetooth (registered trademark) low energy).

[0036] The sound reproduction unit 5 includes a speaker unit 93 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 3 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 5 may be configured with a speaker and drive circuit provided in the communication terminal 7. Alternatively, the sound reproduction unit 5 may be a so-called wireless earphone that is wirelessly connected to the communication terminal 7.

[0037] The lighting device A1 is, for example, a so-called ceiling light installed on the ceiling of a living room of a house, but the lighting device A1 may also be a downlight embedded in the ceiling or a so-called desk lamp placed on a table.

[0038] As shown in FIG. 2, the lighting device A1 includes a main body 90, a cover 91, a pair of panels 92, and a pair of speaker units 93.

[0039] 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 1 and the control unit 3 are housed inside the main body 90. The light source unit 1 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 3 is housed inside the main body 90 between the light source unit 1 and the inner bottom surface of the main body 90.

[0040] 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 1. 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 1 (LED module) enters the cover 91 from the inner surface (top surface) of the cover 91, is diffused by the filler, and then exits the cover 91 from the outer surface (bottom surface) of the cover 91.

[0041] 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 opening end (bottom end) of the main body 90 and faces some of the LEDs of the light source unit 1 (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 A1 essentially has three light source units 1: a light source unit 1 that emits light through the cover 91 and a light source unit 1 that emits light from each of the pair of panels 92.

[0042] 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.

[0043] The server 6 of the lighting system S1 includes a non-transitory storage medium (a storage medium that retains its contents even when power is not supplied), such as a non-volatile semiconductor memory, a hard disk drive (HDD), a solid state drive (SSD), etc. The server 6 stores video data (video data) to be displayed on the display unit 4 and sound (music) data (audio data) to be output from the sound playback unit 5 in the non-transitory storage medium.

[0044] The server 6 also stores lighting control patterns (described later) in a non-transitory storage medium. The lighting control patterns include a dimming control pattern that changes the light intensity in conjunction with a video, and a color adjustment control pattern that changes the light color in conjunction with a video. The server 6 is configured to transmit control data including the lighting control patterns stored in the non-transitory storage medium to the control unit 3 of the lighting device A1 based on an instruction from the lighting control unit 2 of the communication terminal 7.

[0045] (2-2) Operation of the lighting system and lighting device according to the embodiment Next, the operation of the lighting system S1 and the lighting device A1 will be described. In the following description, it is assumed that a user (resident) is playing a video of a person exercising in the living room of a house and exercising in sync with the video.

[0046] First, the user launches the lighting control app installed on the communication terminal 7 (smartphone or tablet). The lighting control app displays a login screen (login screen) on the screen of the communication terminal 7 (the liquid crystal display screen of the display unit 4). When a login ID and password are entered on the login screen, the lighting control app sends the entered login ID and password to the server 6 for authentication. The server 6 compares the login ID and password received from the communication terminal 7 with the user registration information stored in the database, and if they match the user registration information, it sends a reply to the communication terminal 7 indicating that authentication has been completed.

[0047] When the lighting control app receives a reply indicating that authentication has been completed from the server 6, it displays a menu screen G1 on the display unit 4 of the communication terminal 7 (see FIG. 3). In the menu screen G1 shown in FIG. 3, "living room" is selected as the installation location of the lighting device A1, and "yoga" is selected from among the multiple items (yoga, exercise, meditation, and recording) selectable in "living room." Furthermore, the menu screen G1 displays multiple buttons B1 to which multiple courses included in "yoga" 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.

[0048] When any of the buttons B1 is touched, the lighting control app interprets this as the selection of the course assigned to the touched button B1, and creates a control command to play a video corresponding to the selected course and to call up a lighting control pattern. The lighting control app uses the SoC's communication function to send a packet containing the created control command to server 6. For example, if the user touches the second button B1 from the top, the lighting control app sends to server 6 a packet containing a control command corresponding to the "Easy Yoga" course assigned to the second button B1.

[0049] The server 6 receives a packet transmitted from the communication terminal 7 by the lighting control app. In accordance with the control command contained in the received packet, the server 6 reads video data, audio data, and a lighting control pattern corresponding to the "Easy Yoga" course from the video data stored in the non-transitory storage medium. The server 6 transmits a packet containing the read lighting control pattern to the lighting device A1 associated with the communication terminal 7 that sent the control command. The correspondence between the communication terminal 7 and the lighting device A1 is stored as user registration information in the non-transitory storage medium of the server 6.

[0050] On the other hand, the lighting control app transmits a packet including a control command corresponding to the "Easy Yoga" course to the server 6, and then displays a playback screen G2 for playing (streaming) video data on the screen of the display unit 4 (see FIG. 4). When the playback screen G2 is touched, the lighting control app transmits a packet including a command requesting streaming of the video data to the server 6.

[0051] When the server 6 receives a packet including a command requesting streaming of video data, it streams the video data and audio data to the communication terminal 7 in accordance with the command included in the packet.

[0052] The lighting control app displays video streamed from the server 6 on the display unit 4, and transfers audio data streamed from the server 6 to the control unit 3 of the lighting device A1 to be played on the sound playback unit 5 of the lighting device A1. However, the lighting control app may output sound from the speaker of the communication terminal 7 in addition to or instead of the sound playback unit 5 of the lighting device A1.

[0053] Furthermore, the lighting control application causes the control unit 3 of the lighting device A1 to control the light source unit 1 in conjunction with the video displayed on the display unit 4, based on the lighting control pattern included in the packet received from the server 6.

[0054] The control unit 3 of the lighting device A1 controls the light source unit 1 to reproduce the dimming control pattern and the color adjustment control pattern included in the lighting control pattern. The dimming control pattern is, for example, a pattern that gradually reduces the light amount of the light source unit 1 as the video progresses. The color adjustment control pattern is, for example, a pattern that gradually lowers the light color (correlated color temperature) of the light source unit 1 as the video progresses. However, these patterns are examples of dimming control and color adjustment control patterns, and are not limited to the above-mentioned patterns. Note that "reproducing" means that the control unit 3 controls the light source unit 1 according to the lighting control pattern to perform the lighting effect set in the lighting control pattern.

[0055] Thus, the user can relax by watching the video displayed on the display unit 4 and performing several yoga poses shown in the video. The lighting system S1 causes the lighting control unit 2 to control the control unit 3 so as to change the light intensity and light color of the light source unit 1 in conjunction with the yoga video, thereby further relaxing the user. Therefore, the lighting system S1 has the advantage of promoting the use of the lighting control function compared to, for example, a case where the light intensity and color are simply adjusted by the user's operation.

[0056] By the way, when an item other than "Yoga" is selected by the user's touch operation, i.e., "Exercise," "Meditation," or "Record," the lighting control app displays menu screens G3, G4, and G5 corresponding to each item on the display unit 4.

[0057] 5, "living room" is selected as the installation location of the lighting device A1, and "exercise" is selected in "living room." Furthermore, menu screen G3 displays a plurality of buttons B2 to which a plurality of 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 B2 is displayed on the left side of each button B2.

[0058] 6, "Living Room" is selected as the installation location of the lighting device A1, and "Meditation" is selected in "Living Room." Furthermore, menu screen G4 displays a plurality of buttons B3 to which a plurality of courses included in "Meditation" are assigned in a one-to-one correspondence. A thumbnail image of a video corresponding to the course of each button B3 is displayed on the left side of each button B3.

[0059] Menu screen G5 shown in Figure 7 displays the results of tallying the number of times users have selected and performed multiple courses included in "Yoga," "Exercise," and "Meditation" under "Fitness" in the form of numbers, graphs, etc.

[0060] (2-3) Details of the lighting control method according to the embodiment The lighting control method according to the embodiment (hereinafter simply referred to as the lighting control method) controls the light source unit 1 so as to change at least one of the light intensity and the light color in conjunction with the video displayed on the display unit 4. Specifically, the lighting control method is a method in which, in the above-described lighting system S1, the lighting control unit 2 (lighting control application) causes the control unit 3 to control the light source unit 1 so as to change at least one of the light intensity and the light color in conjunction with the video displayed on the display unit 4.

[0061] Therefore, the lighting control method causes the control unit 3 to control the light source unit 1 to change at least one of the light intensity and light color in conjunction with the video displayed on the display unit 4, which has the advantage of promoting utilization of the lighting control function compared to, for example, a case where the light intensity and color are simply adjusted by the user's operation.

[0062] (2-4) Details of the program according to the embodiment The program according to the embodiment is a lighting control application that causes a computer system (SoC of the communication terminal 7) to execute the lighting control method according to the embodiment.

[0063] Therefore, when lighting control is performed using the program (lighting control application) according to the embodiment, there is an advantage that the utilization of the lighting control function can be promoted compared to, for example, when the brightness and color are simply adjusted by the user's operation.

[0064] (2-5) Other advantages of the lighting system according to the embodiment In lighting system S1, lighting control unit 2 controls control unit 3 to reproduce lighting control patterns linked to video. Therefore, lighting system S1 has the advantage that lighting control patterns can be created in advance, which saves users the trouble of creating lighting control patterns themselves, thereby further promoting utilization of the lighting control function.

[0065] Here, the lighting control patterns include a dimming control pattern that changes the light amount and a color adjustment control pattern that changes the light color. Therefore, the lighting system S1 changes the light amount and light color of the light source unit 1 in conjunction with the video, which has the advantage of further promoting the use of the lighting control function.

[0066] Furthermore, it is preferable that the lighting control pattern changes at least one of the light intensity and light color in conjunction with a video of a person performing physical exercise. That is, when a user performs physical exercise in conjunction with a video, the lighting system S1 changes at least one of the light intensity and light color of the light emitted from the light source unit 1 in conjunction with the video, thereby providing a visual effect that can relax the user.

[0067] Furthermore, it is preferable that the lighting control pattern changes at least one of the light intensity and light color in conjunction with a video of a person striking one or more poses (for example, yoga poses). That is, when a user strikes a pose in accordance with the video, the lighting system S1 changes at least one of the light intensity and light color of the light emitted from the light source unit 1 in conjunction with the video, thereby providing a visual effect that can further relax the user.

[0068] Here, the lighting system S1 further includes a sound playback unit 5 that plays sounds combined with the video. The lighting control unit 2 controls the control unit 3 to change at least one of the light intensity and light color in conjunction with the video and sound. Therefore, the lighting system S1 can further relax the user through acoustic effects in addition to the visual effects.

[0069] The lighting system S1 further includes a server 6 that distributes moving images to the display unit 4. Therefore, the lighting system S1 can store moving images to be displayed on the display unit 4 in the server 6, thereby reducing memory consumption of the communication terminal 7 equipped with the display unit 4, for example.

[0070] Furthermore, the server 6 stores lighting control patterns linked to the video, and transmits the lighting control patterns to the control unit 3 based on instructions from the lighting control unit. The lighting control unit 2 then controls the control unit 3 to reproduce the lighting control patterns transmitted from the server 6. Specifically, the lighting control unit 2 causes the control unit 3 to control the light source unit 1 to reproduce the lighting control patterns received from the server 6. Therefore, the lighting system S1 can store lighting control patterns in the server 6, which can reduce memory consumption in the communication terminal 7 equipped with the display unit 4, for example.

[0071] Here, the lighting device A1 is equipped with a sound reproduction unit 5, and causes the control unit 3 to control the light source unit 1 so as to change at least one of the light intensity and light color in conjunction with the video and sound, so that in addition to the visual effect, the acoustic effect can further relax the user.

[0072] Furthermore, the lighting control method controls the light source unit 1 to change at least one of the light intensity and light color in conjunction with the video and the sound combined with the video, so that in addition to the visual effect, the acoustic effect can further relax the user.

[0074] The lighting system (S1) according to the first aspect causes the lighting control unit (2) to control the control unit (3) to change at least one of the light intensity and light color in conjunction with the video displayed on the display unit (4), thereby promoting utilization of the lighting control function compared to, for example, a case where the light intensity and color are simply adjusted by the user's operation.

[0075] A lighting system (S1) according to a second aspect of the present disclosure can be realized by combining it with the first aspect.
