(Knowledge that led to the invention)
For example, a user such as a designer embodies the lighting mode that he/she has in mind using a lighting device. In this case, as a step before realizing his or her own image, the user expresses the desired lighting mode that he or she has imagined as virtual space information on the virtual space displayed on the display screen of the conventional lighting control device. Then, based on the virtual space information displayed on the display screen, the user embodies the desired lighting mode that he or she has imagined using a plurality of lighting devices arranged in the real space.

However, when displaying the desired lighting mode imagined by oneself as virtual space information on a conventional display control device, the virtual space information is based on space information that imitates real space, so it is displayed on the display screen as a display means. The size of the plurality of lighting devices corresponds to the size of the real space, and the size of the plurality of lighting devices displayed on the display screen also becomes smaller.

Therefore, when a user's desired lighting mode is realized in the virtual space displayed on the display screen using multiple lighting devices arranged in the real space, the lighting mode in the real space is The impression given to the user may be weaker than the lighting mode of the space. In other words, the user changes the illumination mode of the lighting device via the display screen, but the illumination mode (or virtual space information) desired by the user deviates from the illumination mode in real space. The impression may be weakened.

Therefore, an object of the present disclosure is to provide a lighting control device, a lighting system, a terminal device, a lighting control method, and a program that can reproduce the lighting mode of a virtual space displayed on a display screen in the lighting mode of a real space. shall be.

<Configuration: Lighting system 1>
First, the configurations of the lighting control device 20a, the lighting system 1, and the terminal device 20 according to the present embodiment will be described.

FIG. 1 is a diagram showing a lighting system 1 according to an embodiment.

As shown in FIG. 1, the lighting system 1 controls lighting modes of the plurality of light sources 11 of the lighting device 2, such as turning on/off, lighting (irradiation) direction, brightness (brightness), light color, etc., according to control information. By doing so, the lighting mode of the lighting device 2 placed in real space can be controlled. Specifically, in this lighting system 1, the terminal device 20 is used to create a virtual space displayed on the display screen 24a of the display unit 24 of the terminal device 20, a virtual space imitating the real space, and a real space. The lighting mode of the lighting device 2 placed in the virtual space is set based on the lighting device 2 placed in the virtual space that imitates the lighting device 2 placed in the virtual space. Thereby, the lighting system 1 determines the lighting mode of the lighting device 2 in the real space, and controls the lighting device 2 based on the determined control information.

Note that this lighting system 1 can also acquire control information in which the lighting mode of the lighting device 2 in the real space is set from an external device via a network, and controls the lighting device 2 based on the acquired control information. Or, by changing the settings included in the control information, it is possible to control the lighting device 2 based on the changed control information. The external devices are systems other than the lighting system 1 and the terminal device 20.

The lighting system 1 includes a plurality of lighting devices 2 and a terminal device 20. In this embodiment, a plurality of lighting devices 2 are illustrated, but since each lighting device 2 has a similar configuration, unless otherwise mentioned, one lighting device 2 will be described.

[Lighting device 2]
The lighting device 2 is placed, for example, on the ceiling, floor, and wall of a building. The outer shape of the lighting device 2 is, for example, approximately spherical or polyhedral. The lighting device 2 has a plurality of light sources 11. The plurality of light sources 11 are arranged throughout the lighting device 2 . Therefore, the lighting device 2 can irradiate in all directions using the plurality of light sources 11. Specifically, the lighting device 2 is a lighting fixture that irradiates (illuminates) light in all directions of 360° using a plurality of light sources 11 that illuminate corresponding directions. The 360° omnidirectional direction refers to all directions from the center of the lighting device 2 to any point on the light emitting surface 2a, and when the light emitting surface 2a of the lighting device 2 is treated as a spherical surface in polar coordinates, the azimuth (declination angle), and any and all orientations defined by the polar angle (zenith angle). Thereby, the illumination device 2 can irradiate light in a spot in an arbitrary direction defined by the azimuth angle (declination angle) and the polar angle (zenith angle). In this embodiment, a case where light is emitted in spots from a part of the light emitting surface 2a of the illumination device 2 will be mainly illustrated and explained.

In this embodiment, a lighting device that emits light in all directions is illustrated as the lighting device 2, but the lighting device 2 is not limited to this, and may be a lighting device such as a ceiling light or a downlight.

The lighting device 2 irradiates light in any direction with the lighting device 2 as the center by selectively causing the plurality of light sources 11 to emit light. That is, the illumination direction of the light emitted from the illumination device 2 is arbitrary. For example, the lighting device 2 can emit light in all directions of 360° by emitting light from all the light sources 11 at the same time, or emit light in all directions of 360° by emitting light from some of the light sources 11. Shine light only on the object. In other words, the lighting device 2 not only functions as a 360° omnidirectional light but also functions as a spotlight.

The lighting device 2 functions as a spotlight, and causes the plurality of light sources 11 to selectively emit light so that the irradiated light moves. In this case, in this lighting device 2, the plurality of light sources 11 selectively emit light so that the shape of the irradiation area on the wall surface is approximately circular, but the invention is not limited thereto. For example, the shape of the irradiation area of the illumination device 2 may be rectangular or approximately elliptical.

Further, the lighting device 2 has a dimming control function and a color toning control function. Specifically, the lighting device 2 changes the luminance (brightness) and light color (color temperature or color) of the light that the lighting device 2 emits. In this embodiment, the lighting device 2 changes the luminance (brightness) and light color of light for each of the plurality of light sources 11.

Furthermore, the illumination device 2 in this embodiment irradiates a target object such as a wall surface with light in full color evenly. For this reason, as each light source 11, a three-color light source of RGB is used, as will be described later. Further, the plurality of light sources 11 are arranged with high density and uniformly distributed. Thereby, by controlling the light emitted by the lighting device 2, the space in which the lighting device 2 is arranged is created.

Furthermore, unlike a display that displays an image, the lighting device 2 in this embodiment needs to illuminate a wall surface, etc., so the light source 11 needs to have a high light output. Therefore, the brightness of each light source 11 is higher than that of an LED (Light Emitting Diode) light source used in a backlight of a liquid crystal display or an LED light source used in an LED display.

The lighting device 2 includes a plurality of light sources 11 , a lighting control section 12 , a power supply section 13 , a storage section, and a communication section 14 .

Each of the plurality of light sources 11 is a light emitting module having at least one light emitting element. In this embodiment, each light source 11 has a plurality of light emitting elements. Each light source 11 emits light in accordance with instructions from the illumination control section 12 based on control information.

The plurality of light sources 11 are arranged throughout the lighting device 2 . That is, the plurality of light sources 11 are scattered so that light can be emitted from the illumination device 2 in all directions. Each light source 11 illuminates a corresponding direction. The directions of light emitted by each light source 11 may be different. Each of the plurality of light sources 11 emits light toward the outside of the lighting device 2 . Specifically, the optical axis of each light source 11 is in a direction perpendicular to the tangent to the outer surface (light emitting surface) of the spherical exterior cover that covers the plurality of light sources 11 . The optical axis is a straight line along the main light emitted from each light source 11.

Further, each light source 11 emits light of two or more colors. Specifically, each light source 11 is a three-color light source of RGB, and emits three monochromatic lights of red light, blue light, and green light, and can dim these three monochromatic lights. It emits colored light or white light obtained by

Specifically, each light source 11 has a surface mount device (SMD) type LED element in which an LED is packaged, and specifically, includes a container (package) and a device mounted in the container. It has a plurality of LED chips and a sealing member that seals the plurality of LED chips. In this embodiment, a red LED chip that emits red light, a blue LED chip that emits blue light, and a green LED chip that emits green light are mounted as the plurality of LED chips. The sealing member is a translucent insulating resin material such as silicone resin. Note that a light diffusing material such as silica, a filler, and the like may be dispersed in the sealing member.

The lighting control unit 12 is a control circuit that controls each part of the lighting device 2. The lighting control unit 12 performs various controls by, for example, having a processor execute a program stored in a storage unit. The processor may be an MPU (Micro Processing Unit), a CPU (Central Processing Unit), a DSP (Digital Signal Processor), a GPU (Graphical Processing Unit), or an S It is configured by an OC (System on a Chip) or the like.

The lighting control unit 12 controls the plurality of light sources 11. Specifically, the lighting control unit 12 acquires (receives) control information from the lighting control device 20a, and controls each light source 11 to emit light in the lighting mode of the lighting device 2 according to the acquired control information. The light emitting mode (illumination mode) of light emitted by a predetermined light source 11 included in the control unit 11 is controlled. That is, the illumination control unit 12 individually controls the light emission mode of the light emitted by all the light sources 11 included in the illumination device 2. For example, the illumination control unit 12 controls the light emitted by all the light sources 11 to turn on and off (on, off), change the brightness, and change the light color.

Further, the lighting control unit 12 individually controls the light emission mode of each light source 11 according to the control information received from the lighting control device 20a.

Here, the control information includes an identifier of the light source 11 to emit light, a color emitted by the light source 11, a period during which the light source 11 emits light, and the like. That is, the control information includes information for lighting each light source 11 in a predetermined light emission mode (color of light emitted by the light source 11, period of time during which the light source 11 emits light, etc.). Further, the control information includes a plurality of light emitting steps for lighting each light source 11 in a predetermined light emitting mode.

The power supply section 13 has a function of supplying power to each section of the lighting device 2. The power supply unit 13 is, for example, a power supply circuit in which a plurality of electronic components are mounted on a printed circuit board. The power supply unit 13 generates, for example, driving power for causing each of the plurality of light sources 11 to emit light. Specifically, the power supply section 13 generates driving power for causing the light sources 11 to emit light, and supplies this driving power to each light source 11. That is, the power supply unit 13 converts commercial AC power into DC power, and supplies the DC power to each light source 11 as driving power for causing the light source 11 to emit light, thereby causing the light source 11 to emit light.

The communication unit 14 has a function of communicating with the terminal device 20. Specifically, the communication unit 14 receives control information for controlling the lighting mode of the lighting device 2 in real space from the terminal device 20. The control information received by the communication section 14 is output to the lighting control section 12. The communication method by the communication unit 14 is, for example, WAN (Wide Area Network), LAN (Local Area Network), power line communication, infrared communication, short-range wireless communication (for example, Bluetooth (registered trademark) communication), or mobile phone communication. This is a communication method such as mobile communication.

Control information and the like acquired by the lighting control unit 12 are periodically stored in the storage unit. The storage unit includes, for example, a primary storage device such as a RAM (Random Access Memory) and a ROM (Read Only Memory). Further, the storage unit may include a secondary storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and a tertiary storage device such as an optical disk and an SD card.

[Terminal device 20]
The terminal device 20 displays virtual space information corresponding to the real space information on the display unit 24 by acquiring real space information indicating the real space in which the lighting device 2 is placed. Here, the real space information includes information indicating the size and shape of the actual space (real space or actual space) where the lighting device 2 is placed, and the location of the lighting device 2 placed in the real space (described later). (coordinate data), size, shape, etc. The real space is a real space that actually exists, such as a room in a facility, a stage, etc. Further, the real space information may include the size, position, brightness, light color, etc. of the illumination mode of the lighting device 2 in the real space. Further, the virtual space information corresponds to the real space information, and includes information indicating a virtual space that is a virtual space imitating the real space shown in the real space information, and each of the plurality of lighting devices 2 arranged in the virtual space. , brightness information and color information of the light emitted from each of the plurality of lighting devices 2 (illumination mode such as dimming and color adjustment of each of the plurality of lighting devices 2). Upon acquiring such real space information, the terminal device 20 generates virtual space information based on the real space information, and displays the virtual space information on the display unit 24. Note that the virtual space information may only include information indicating the virtual space, information indicating the positions of each of the plurality of lighting devices 2 in the virtual space, and information indicating the size of the lighting mode of the lighting devices 2 in the virtual space.

The terminal device 20 includes a lighting control device 20a that controls the lighting mode of each of the plurality of lighting devices 2 in real space, and a power supply section (not shown).

The lighting control device 20a includes an acquisition section 21, an input section 22, a processing section 23, a display section 24, a communication section 26, and a storage section 25. Note that the lighting control device 20a may not include the input section 22, the display section 24, the communication section 26, and the storage section 25, and these are not essential components.

The acquisition unit 21 acquires real space information regarding the real space in which the plurality of lighting devices 2 are actually arranged and the arrangement positions. That is, the real space information is information regarding the real space where the plurality of lighting devices 2 are actually arranged and the arrangement position where the plurality of lighting devices 2 are actually arranged. The acquisition unit 21 acquires real space information based on input from the user to the terminal device 20 according to an operation. The acquisition unit 21 is, for example, an imaging device, a sensor, etc., and captures or senses real space and a plurality of illumination devices 2 arranged in the real space, thereby obtaining captured image data or sensed image data. Real space information such as sensor values may also be acquired. Note that the acquisition unit 21 may acquire the real space information, including the illumination mode of the illumination device 2 in the real space, by inputting, imaging, or sensing according to the operation. The acquisition unit 21 outputs the acquired real space information to the processing unit 23. Note that the acquisition unit 21 may acquire information input in response to an operation on the input unit 22, which will be described later, as real space information or the like.

The input unit 22 is an operation unit that receives input according to an operation on the terminal device 20 from a user. The input unit 22 is, for example, a character information input device such as a keyboard, a pointing device such as a mouse or a touch panel, a button, a touch sensor, a touch pad, or the like. The input unit 22 outputs instructions input by operation to the processing unit 23 . Specifically, when the input unit 22 receives an instruction to change the lighting mode of the plurality of lighting devices 2 in the virtual space, the input unit 22 outputs the input instruction to the processing unit 23 . That is, the user instructs, via the input unit 22, to set the illumination mode of the plurality of lighting devices 2 based on the virtual space information displayed on the display screen 24a. A plurality of lighting devices 2 in virtual space information are set.

The processing unit 23 generates virtual space information including a virtual space imitating the real space displayed on the display screen 24a. That is, when the processing unit 23 acquires the real space information from the acquisition unit 21, the processing unit 23 uses the real space indicated in the real space information and the coordinate data indicating the arrangement positions of the plurality of lighting devices 2 arranged in the real space, etc. and generate virtual space information. Specifically, the processing unit 23 generates a virtual space based on image data or sensor values of the real space indicated by the acquired real space information. Virtual space is expressed as if it were substantially the same space as real space, but it is expressed in a virtual two-dimensional plane or three-dimensional space. When converting real space information to generate virtual space information, the processing unit 23 performs image processing such as encoding processing, compression processing, decoding processing, enlargement/reduction processing (resizing), noise reduction processing, and color conversion processing. conduct. Furthermore, the processing unit 23 generates control information to be transmitted to the lighting device 2 in the real space from among the lighting modes in the virtual space, based on the respective positions of the plurality of lighting devices 2 arranged in the virtual space. The processing unit 23 transmits the generated control information to the lighting device 2 via the communication unit 26.

Further, the processing unit 23 adjusted the relative sizes of the plurality of lighting devices 2 virtually arranged in the virtual space according to the respective arrangement positions of the plurality of lighting devices 2 shown in the real space information. Generate virtual space information. In other words, the processing unit 23 determines the size of the real space, the size and position of each of the plurality of lighting devices 2 arranged in the real space, the size of each illumination mode of the plurality of lighting devices 2 in the real space, The size, position, etc. of each of the plurality of lighting devices 2 arranged in the virtual space are changed and adjusted according to the position, brightness, light color, etc. Therefore, the size (first relative size) of the lighting device 2 with respect to the size of the virtual space in the virtual space information is the size (second relative size) of the lighting device 2 in the real space of the real space information. s) is different. Here, the size of the lighting device 2 in the virtual space is the planar size when viewed on the display screen 24a, and is the planar area displayed on the display screen 24a. In the present embodiment, the processing unit 23 determines the second relative size of the plurality of illumination devices 2 in the virtual space, rather than the first relative size of the plurality of illumination devices 2 arranged in the real space information. Adjust to make it relatively large. By outputting the virtual space information generated by the processing unit 23 to the display unit 24, the presence of each of the plurality of lighting devices 2 is displayed on the display screen 24a of the display unit 24 as if it were exaggerated in the virtual space. displayed.

Further, the processing unit 23 may adjust the relative sizes of the plurality of lighting devices 2 so that their respective positions do not overlap. That is, when adjusting the size of each of the plurality of lighting devices 2 arranged in the virtual space to be larger, the processing unit 23 adjusts the size of the plurality of lighting devices 2 displayed on the display screen 24a of the display unit 24. Adjust the size so that their positions do not overlap. The respective positions and sizes of the plurality of lighting devices 2 are the respective positions and sizes of the plurality of lighting devices 2 in the virtual space, and the positions and sizes of the respective lighting modes of the plurality of lighting devices 2 in the virtual space. include. Therefore, if the respective positions of a plurality of lighting devices 2 overlap, if adjacent lighting devices 2 overlap, or if the illumination modes of adjacent lighting devices 2 overlap in the virtual space, a predetermined lighting device 2 may be placed on the display screen. If the lighting mode of a predetermined lighting device 2 overlaps with another lighting device 2 or the lighting mode of the lighting device 2 when moving in the vertical direction and horizontal direction in the virtual space displayed on the display screen 24a, the lighting mode of the predetermined lighting device 2 in the virtual space is This is a case where the illumination mode overlaps with another illumination device 2 or the illumination mode of the illumination device 2 when moving in the vertical and horizontal directions. The processing unit 23 outputs the generated virtual space information to the display unit 24, so that a plurality of lighting devices 2 whose positions with respect to the lighting devices 2 do not overlap are displayed on the display screen 24a of the display unit 24.

Further, the processing unit 23 controls the plurality of lighting devices 2 and the plurality of lighting devices in the virtual space so that the positions of two adjacent lighting devices 2 among the plurality of lighting devices 2 arranged in the virtual space do not overlap. The center position of at least one of the aspects may also be adjusted. In other words, the processing unit 23 not only simply increases the size of each of the plurality of lighting devices 2 arranged in the virtual space, but also handles the problem of overlapping lighting when the respective positions of the plurality of lighting devices 2 overlap after increasing the size. By moving the center position of the device 2, the position of the moved lighting device 2 is adjusted. The central position of the lighting device 2 mainly refers to the center of the lighting mode of the lighting device 2, but may also include the center of the lighting device 2. Since the display screen 24a of the display unit 24 is expressed in two-dimensional coordinates, the processing unit 23 moves the center position of the overlapping lighting devices 2 in the two-dimensional coordinates. For example, the processing unit 23 may move the center position of at least one lighting device 2 among the plurality of overlapping lighting devices 2. By outputting the virtual space information adjusted and generated by the processing unit 23 to the display unit 24, the display screen 24a of the display unit 24 displays a plurality of lighting devices 2 and lighting modes in the virtual space whose arrangement positions do not overlap. is displayed.

The display unit 24 has a display screen 24a that displays virtual space information. The display unit 24 displays the virtual space information generated by the processing unit 23 on the display screen 24a. The display unit 24 includes a touch panel that functions as the input unit 22 and the display screen 24a. A GUI (Graphical User Interface) screen suitable for touch operations by a user is displayed on the touch panel. Note that the user interface is not limited to the touch panel, and may include the display screen 24a and the input section 22 individually. The display screen 24a is a display device such as a liquid crystal display device or an organic EL device. The display section 24 is an example of an output section. Note that the display unit 24 does not need to be included in the configuration of the lighting control device 20a. In this case, the output interface of the lighting control device 20a is an example of an output section.

The communication unit 26 has a function of communicating with the terminal device 20. Specifically, when the communication unit 26 acquires control information for controlling the illumination mode of the illumination device 2 in real space from the processing unit 23, the communication unit 26 transmits the acquired control information to the illumination device 2. The communication method by the communication unit 26 is, for example, WAN, LAN, power line communication, infrared communication, short-range wireless communication (for example, Bluetooth (registered trademark) communication), or mobile communication for a mobile phone.

The storage unit 25 periodically stores virtual space information, control information, etc. generated by the processing unit 23. The storage unit 25 outputs virtual space information to the display unit 24 or control information in accordance with an operation input to the input unit 22 . The storage unit 25 includes, for example, a primary storage device such as a RAM and a ROM. Furthermore, the storage unit 25 may include a secondary storage device such as an HDD and an SSD, and a tertiary storage device such as an optical disk and an SD card.

The power supply section has a function of supplying power to each section of the terminal device 20. The power supply section includes a power supply circuit that generates drive power for driving each section, and a battery that supplies power necessary for each operation.

The processing unit 23 adjusts (enlarges/reduces) the size of each of the plurality of lighting devices 2 in the virtual space according to the arrangement position of each of the plurality of lighting devices 2 shown in the real space information. Generate spatial information. As shown in FIGS. 3A and 3B, the processing unit 23 determines the respective sizes (first relative sizes) of the plurality of lighting devices 2 actually arranged in the room with respect to the size of the room in FIG. 3A. Rather, the respective sizes (second relative sizes) of the plurality of lighting devices 2 in the virtual space with respect to the size of the virtual space displayed on the display screen 24a of the display unit 24 in FIG. 3B, Adjust to make it relatively large. This is because unless the respective sizes of the plurality of lighting devices 2 arranged in the virtual space are made relatively large with respect to the size of the lighting mode of the virtual space displayed on the display screen 24a, the illumination desired by the user cannot be achieved. Control information as an aspect cannot be sufficiently expressed by the illumination device 2 in real space. That is, the control information according to the lighting mode transmitted to the plurality of lighting devices 2 in the real space may become insufficient, and there is a possibility that the lighting mode desired by the user cannot be fully realized. Therefore, as shown by the broken line in FIG. 3B, the processing unit 23 determines the relative size of the illumination aspect 2a of the illumination device 2 in the virtual space than the illumination aspect 2b that is simply reduced and displayed on the display screen 24a. Adjust to make it larger. A lighting mode 2b indicated by a two-dot chain line in FIG. 3B is a case where the size of the lighting mode of the lighting device 2 placed in the room is reduced to match the size of the display screen 24a.

Further, the size of the lighting mode is preferably the maximum size when the display screen 24a is divided approximately equally into the number of lighting devices 2 in the width direction (vertically or horizontally) of the display screen 24a, for example. In this embodiment, since three lighting devices 2 are illustrated, the size of the lighting mode is defined by dividing the width of the display screen 24a into three equal parts as the diameter of the lighting mode. The processing unit 23 increases the size of the illumination mode 2a of the illumination device 2 up to about 40 times the size of the illumination device 2 in the uniformly reduced virtual space, preferably from 5 times to 40 times. Expand within the range. Therefore, the display screen 24a of the display unit 24 does not simply resize and display the real space and the plurality of lighting devices 2 in the real space. The processing unit 23 outputs the generated virtual space information to the display unit 24, as shown in FIG. 3B.

By outputting the virtual space information generated by the processing unit 23 to the display unit 24 of the terminal device 20 (S13), the display screen 24a of the display unit 24 of the terminal device 20 displays the virtual space indicated by the virtual space information, the virtual A plurality of lighting devices 2 in the space and lighting modes of the plurality of lighting devices 2 are displayed. The display screen 24a of the display unit 24 shows a virtual space including a virtual space and a plurality of lighting devices 2 arranged in the virtual space, which simulates the real space in FIG. 3A and the plurality of lighting devices 2 arranged in the real space. Displayed as information. Furthermore, the lighting modes of the plurality of lighting devices 2 are also expressed on this display screen 24a. Although the display screen 24a in FIG. 3B shows an example in which the back wall of the room and the lighting mode illuminating the back wall are displayed, the display screen 24a is not limited to this. For example, the display screen 24a may display the illumination mode in which the left and right side walls, the ceiling, and the floor of the room are illuminated.

By operating the input unit 22 of the terminal device 20, the user sets the lighting mode of each of the plurality of lighting devices 2 based on the virtual space information displayed on the display screen 24a. Thereby, the processing unit 23 of the terminal device 20 generates control information according to the set lighting mode. Once the control information is generated, the user transmits the generated control information to each of the plurality of lighting devices 2 via the communication unit 26 by operating the input unit 22 of the terminal device 20 .

Each of the plurality of lighting devices 2 acquires the control information transmitted from the terminal device 20 (S14). Specifically, when each of the plurality of lighting devices 2 receives the control information, the light source 11 included in each light source 11 emits light in a light emission mode according to the control information received by the lighting control unit 12. Controls the manner in which light is emitted. That is, each of the plurality of lighting devices 2 illuminates the room according to the control information (S15). Thereby, the room is illuminated according to the control information set on the terminal device 20. Then, in the lighting system 1, the process ends.

Here, if the relative size of the plurality of lighting devices 2 in the virtual space is increased, at the time of a certain performance, the plurality of lighting devices 2 arranged in the real space will produce a performance that is not intended by the user. Other discomfort may occur. For example, in FIGS. 3A and 3B, the effect intended by the user is performed, making it difficult for the user to feel uncomfortable, but in FIGS. 4A and 4B, which are different effects from those shown in FIGS. 3A and 3B, the effect is not intended by the user. The illumination mode of the plurality of lighting devices 2 in real space may give a sense of discomfort.

FIG. 4A is a diagram showing a real space as real space information, a plurality of lighting devices 2 arranged in the real space, and another lighting mode. FIG. 4B is a diagram showing a virtual space displayed on the display screen 24a as virtual space information and another illumination mode 2a in the virtual space.

Also in FIGS. 4A and 4B, the relative sizes of the plurality of lighting devices 2 in the virtual space are increased similarly to FIGS. 3A and 3B. When the real space information in FIG. 4A is displayed as virtual space information on the display screen 24a, for example, as shown in the display screen 24a in FIG. ing.

Specifically, as shown in FIG. 4A, on the display screen 24a of the terminal device 20, light emitted by the plurality of lighting devices 2 in the virtual space is displayed from one side of the display screen 24a to the other side on the opposite side. The virtual space information set to extend up to The plurality of lighting devices 2 arranged in the room perform illumination based on control information set based on the virtual space information in order to realize the lighting mode of this virtual space information in real space. In this case, even if a plurality of lighting devices 2 arranged in the room are illuminated, the actual illuminated position will shift and deviate from the virtual space information displayed on the display screen 24a, as shown in FIG. 4B. There are cases.

In this way, in the case where the illumination mode in the real space and the illumination mode in the virtual space shown in FIGS. 3A and 3B are composed of diagonal lines that are inclined with respect to the left-right direction, It is difficult to feel strange in the illumination modes of the plurality of lighting devices 2, but when the illumination modes of the real space and the virtual space shown in FIGS. 4A and 4B are composed of lines substantially parallel to the left-right direction, , the lighting conditions of the plurality of lighting devices 2 in the real space may give a sense of discomfort.

[Operation example 2]
This operation example will be explained using FIGS. 5A and 5B. FIG. 5A is a diagram showing a real space as real space information, a plurality of lighting devices 2 arranged in the real space, and yet another lighting mode. FIG. 5B is a diagram showing a virtual space and lighting modes 2a of yet another plurality of lighting devices 2 in the virtual space as virtual space information. 5A and 5B illustrate an illumination mode in which the color gradually changes from the left side to the right side (for example, a rainbow-colored illumination mode). In FIG. 5B, the color changes from the left end of the display screen 24a to red, yellow, green, blue, and purple at the right end are illustrated by dot hatching.

In this operation example, as shown in FIGS. 5A and 5B, the processing unit 23 adjusts the relative sizes of the plurality of lighting devices 2 so that their positions do not overlap. Specifically, the processing unit 23 adjusts the relative size so that the illumination modes 2a of the plurality of illumination devices 2 in the virtual space do not overlap. As shown by two-dot chain lines arranged in a grid pattern in the horizontal and vertical directions, the processing unit 23 selects adjacent lighting devices 2 in the lighting mode 2a of the plurality of lighting devices 2 in the virtual space displayed on the display screen 24a. Virtual space information is generated in which the illumination modes 2a are adjusted so that they do not overlap in the vertical and horizontal directions. Thereby, the processing unit 23 displays the illumination modes 2a of adjacent illumination devices 2 on the display screen 24a so that they do not overlap in the vertical and horizontal directions. At this time, the processing unit 23 adjusts the size of the illumination aspect 2a of the illumination device 2 so that the illumination aspect 2a of the illumination device 2 has a maximum size without overlapping in the vertical and horizontal directions. Note that the processing unit 23 may adjust the size of the lighting device 2.

In this operation example, the sense of discomfort as shown in FIGS. 4A and 4B does not occur. However, in this operation example, during a certain performance, the plurality of lighting devices 2 arranged in the real space may produce a performance that is not intended by the user, resulting in another sense of discomfort. For example, although the discomfort as shown in FIGS. 4A and 4B is less likely to occur, in FIG. 5A, the only changes from the left end of the display screen 24a to yellow, green, and blue at the right end of the display screen 24a are caused by the difference between the plurality of lighting devices 2 in real space. It is not embodied in the lighting aspect. That is, as shown in FIGS. 5A and 5B, the rainbow-colored illumination mode displayed on the display screen 24a is not realized. In this way, since the user is not intended by the effect, the illumination mode of the plurality of lighting devices 2 in the real space may give a further sense of discomfort.

[Operation example 3]
This operation example will be explained using FIGS. 6A and 6B. FIG. 6A is a diagram showing a real space as real space information, a plurality of lighting devices 2 in the real space, and another lighting mode. FIG. 6B is a diagram showing still another illumination mode of the virtual space and the plurality of lighting devices 2 in the virtual space as virtual space information.

In this operation example, as shown in FIGS. 6A and 6B, the processing unit 23 controls the plurality of lighting devices 2 so that the positions of adjacent lighting devices 2 among the plurality of lighting devices 2 arranged in the virtual space do not overlap. The respective center positions with respect to the lighting device 2 are adjusted. Specifically, the processing unit 23 adjusts the lighting modes 2a of the plurality of lighting devices 2 so that the positions of the lighting modes 2a of adjacent lighting devices 2 among the plurality of lighting devices 2 do not overlap in the virtual space. Adjust the center position of each. As shown by two-dot chain lines in the left-right direction and the up-down direction, the processing unit 23 determines that in the illumination mode 2a of the illumination device 2 in the virtual space displayed on the display screen 24a, the illumination mode 2a of the adjacent illumination device 2 is vertically Virtual space information is generated in which the center position of the illumination mode 2a of at least one of the illumination devices 2 among the illumination modes 2a of the plurality of illumination devices 2 is adjusted so as not to overlap in the direction and the left-right direction. Thereby, the processing unit 23 causes the display screen 24a to display the illumination aspect 2a of the illumination device 2 that has been moved so that the illumination aspect 2a of the adjacent illumination device 2 does not overlap in the vertical and horizontal directions. At this time, the processing unit 23 adjusts the illumination device 2 and the illumination aspect 2a of the illumination device 2 so that the illumination aspect 2a of the illumination device 2 has a maximum size in the virtual space without overlapping in the vertical and horizontal directions. Adjust the size. Note that the processing unit 23 may adjust the size of the lighting device 2.

In this operation example, the sense of discomfort as shown in FIGS. 5A and 5B does not occur. However, in this operation example, during a certain performance, the plurality of lighting devices 2 arranged in the real space may produce a performance that is not intended by the user, resulting in another sense of discomfort. For example, although the discomfort as shown in FIGS. 5A and 5B is less likely to occur, for example, the angle of the lower light L1 irradiated onto the back wall of the room in FIG. 6A with respect to the horizontal direction (or horizontal direction) is as shown in FIG. 6B. This angle is smaller than the angle of the lower light L2 displayed on the display screen 24a with respect to the horizontal direction. By adjusting the respective center positions of the plurality of lighting devices 2 arranged in the virtual space, in the illumination mode of the plurality of lighting devices 2 in the real space, the sense of discomfort in FIG. 4A compared to FIG. 4B and the sense of discomfort in FIG. 5A compared to FIG. 5B are reduced. becomes less likely to occur. However, as shown in FIGS. 6A and 6B, a sense of discomfort may occur due to the difference in aspect ratio, and the lighting mode of the plurality of lighting devices 2 in the real space may be affected due to unintended effects being produced. Other discomfort may occur.

In these operation examples 1 to 3, the user may feel uncomfortable due to the deviation from the actual image, that is, the overlap of the illumination modes 2a, during a certain specific performance. Further, during a certain performance, the aspect ratio of the display screen 24a changes, so that the lighting mode of the virtual space displayed on the display screen 24a may appear distorted in the lighting mode of the real space. However, by appropriately combining operation examples 1 to 3, even if the user feels strange due to the deviation from the actual image, that is, the overlap of the lighting modes 2a, in a certain specific performance, the lighting control device 20a can control the lighting device 2. Since the size of the illumination mode 2a is adjusted and displayed on the display screen 24a, it is expected that the user's discomfort will be suppressed.

Note that the lighting modes 2a of the plurality of lighting devices 2 in the virtual space may be allowed to overlap by less than about 30% in the vertical or horizontal direction of the display screen 24a.
