[Communication terminal]
The communication terminal 20 controls the plurality of lighting fixtures 10. Specifically, the communication terminal 20 transmits the lighting control information to each of the plurality of lighting fixtures 10 to control the dimming and toning of the plurality of lighting fixtures 10. In the present embodiment, as shown in FIG. 2, the space 50 is provided with six lighting fixtures 10a to 10f. For this reason, the communication terminal 20 controls the lighting state of the space 50 by controlling the dimming and toning of each of the six lighting fixtures 10a to 10f.

The communication terminal 20 is, for example, a mobile terminal such as a mobile phone, a smartphone, or a tablet terminal. As illustrated in FIG. 1, the communication terminal 20 includes an acquisition unit 21, a transmission unit 22, and a reception unit 23.

Hereinafter, each component included in the communication terminal 20 will be described in detail.

[Acquisition part]
The acquisition unit 21 acquires input information. The input information includes layout information, basic information, lighting information, and impression information. Details of each information will be described later.

The acquisition unit 21 specifically includes a camera and a user interface that receives an operation from the user. The user interface includes, for example, a GUI (Graphical User Interface), a touch panel, a physical operation button, a microphone, and the like. The acquisition unit 21 stores the acquired information in a storage unit (not shown).

The layout information is layout information of a space 50 in which a plurality of lighting fixtures 10 are arranged. Specifically, the layout information indicates the nature of the space 50 and the number and arrangement of the plurality of lighting fixtures 10. The property of the space 50 is, for example, the type (name of the room) and the size of the space 50.

FIG. 3 is a diagram showing an example of layout information according to the present embodiment. In the example shown in FIG. 3, the space 50 is a living / dining room of 20 m ² , and four, one, and one lighting fixture 10 are arranged on the ceiling 51, the floor 52, and the wall 53 or the wall 54, respectively. It has been shown.

Specifically, the layout information corresponds to a plan view (floor plan) showing a floor plan of the room (space 50). In the floor plan, the arrangement of the plurality of lighting fixtures 10 provided in the space 50 is shown.

For example, the user activates the lighting effect program (application) by operating the touch panel (acquisition unit 21) of the communication terminal 20. The lighting effect program displays on the touch panel a GUI for allowing the user to input the layout (room layout) of the space 50.

Thus, the acquisition unit 21 can acquire the input information as the layout information by allowing the user to input the size, property, and the like of the space 50. Note that the lighting effect program may allow the user to input an address indicating a location where an image file indicating a floor plan of the space 50 is stored.

Basic information is information indicating the performance of the plurality of lighting fixtures 10. The performance includes functions that the luminaire 10 can perform. Specifically, the basic information indicates whether or not the lighting fixture 10 can be dimmed and whether or not toning is possible.

FIG. 4 is a diagram showing an example of basic information according to the present embodiment. The basic information includes information indicating the name, model number, function, and arrangement of the lighting fixture. In the example shown in FIG. 4, the ceiling fixture A, the ceiling fixture C, the floor fixture A, and the wall fixture A can be dimmed and toned, whereas the ceiling fixture B and the ceiling fixture D are only dimmable. Is possible.

The name, model number, and arrangement of the lighting fixture are set based on an operation from the user, for example. The function of the luminaire may be set based on, for example, an operation from the user, or may be set by referring to an external database based on the set model number.

For example, the lighting effect program displays on the touch panel a GUI for allowing the user to input the name, model number, and arrangement of the lighting fixture. Thereby, the acquisition part 21 can acquire the input information as basic information by making a user input the name, model number, arrangement | positioning, etc. about each of the some lighting fixture 10. FIG.

The lighting information is information indicating the current lighting state by the plurality of lighting fixtures 10. Specifically, the illumination information is an image obtained by shooting the space 50 as shown in FIG. FIG. 5 is a diagram showing an image of the space 50 in which the current illumination state according to the present embodiment is realized.

“The current lighting state” is the lighting state of the space 50 before the lighting effect according to the present embodiment is performed. For example, the current lighting state is the lighting state of the space 50 when the user is operating the communication terminal 20 to perform lighting effects. Specifically, the current lighting state is shown in an image generated by the user shooting the space 50 using the camera of the communication terminal 20.

For example, the lighting effect program causes the user to photograph the space 50 using the camera of the communication terminal 20. For example, the lighting effect program prompts the user to shoot by displaying a message such as “Please take a picture of the room” on the display of the communication terminal 20 or by outputting it from a speaker or the like. When the user operates the camera to photograph the space 50, the acquisition unit 21 can acquire an image in which the space 50 is captured.

Note that the illumination information is not limited to the image, and may be the current setting values of the dimming rate and the color temperature of each of the plurality of lighting fixtures 10 arranged in the space 50.

The impression information is information indicating an impression of a space where a predetermined lighting state is realized. In the present embodiment, the impression information includes an image in which a space in which an ideal lighting state of the user is realized is captured. The impression information corresponds to information indicating the target setting values of the dimming rate and the color temperature of the plurality of lighting fixtures 10 arranged in the space 50.

The “ideal lighting state” of the user is a lighting state that the user wants to realize in the space 50. That is, the ideal lighting state corresponds to a lighting state that is a setting target for the dimming rate and the color temperature of the plurality of lighting fixtures 10. The acquisition unit 21 acquires an image input by the user as an image of the ideal space as a predetermined image included in the impression information.

FIG. 6 is a diagram showing an image of a space (ideal space 60) in which an ideal illumination state according to the present embodiment is realized.

The image obtained by photographing the ideal space 60 is acquired, for example, by the user photographing the ideal space 60 in advance, and stored in a storage unit (not shown) of the communication terminal 20. For example, when a user visits a friend's house, a model house, a showroom, or the like, it is acquired by photographing a room in which a favorite lighting state is realized as an ideal space 60.

Note that the image in which the ideal space 60 is photographed may not be an image photographed by the user. For example, an image included in a website or an image obtained by scanning or photographing a magazine or the like may be used. For example, when the user performs an operation of downloading an image in which the ideal space 60 is captured to the communication terminal 20, the acquisition unit 21 can also acquire the image.

Further, the impression information may further include a keyword (second keyword) indicating an impression that the user likes. Specifically, the keyword is a sensitivity word representing an impression felt by the user with respect to an ideal lighting state. The keyword is, for example, a word having directionality based on a predetermined scale. In the present embodiment, the keyword is a word based on the user's arousal level, such as “clean”, “easy”, “slightly relaxed”, “relaxed”, and the like. There is a difference in impression (distance) between “clean” and “relaxation”, and the keyword includes the word “slightly”, giving an intermediate impression between “clean” and “relaxation”. Can be represented.

[Transmitter and Receiver]
The transmission part 22 transmits several lighting control information to the control part 12 of the lighting fixture 10 corresponding to each. For example, when the illumination control information is received from the server device 30 by the reception unit 23, the transmission unit 22 transmits the received illumination control information to the control unit 12 of the corresponding lighting fixture 10.

The transmission unit 22 further transmits input information to the server device 30 via the network 40. For example, when input information is acquired by the acquisition unit 21, the transmission unit 22 transmits the acquired input information to the control information generation unit 31 of the server device 30.

In addition, the transmission part 22 may transmit illumination control information based on user operation. For example, when the receiving unit 23 receives the lighting control information, the transmitting unit 22 does not transmit the lighting control information. At this time, for example, the illumination control information is stored in a storage unit (not shown) of the communication terminal 20 or the like. The transmission unit 22 may read and transmit the illumination control information from the storage unit when receiving an instruction for illumination control from the user. Thereby, an illumination effect can be performed at an arbitrary timing.

The receiving unit 23 acquires lighting control information from the server device 30 via the network 40.

The transmission unit 22 and the reception unit 23 are communication interfaces that can communicate with each of the plurality of lighting fixtures 10 and the server device 30. Communication between the transmission part 22 and the control part 12 of the lighting fixture 10 is wireless communication, for example. The wireless communication is performed based on a predetermined wireless communication standard such as Bluetooth (registered trademark), ZigBee (registered trademark), or Wi-Fi (registered trademark). The communication between the transmission unit 22 and the control unit 12 may not be wireless communication but may be wired communication.

The network 40 is, for example, the Internet. The transmission unit 22 and the reception unit 23 communicate with the server device 30 by connecting to the network 40 via a router (not shown) or the like.

[Server device]
The server device 30 is a device that generates lighting control information for realizing an ideal lighting state for each user. The server device 30 is, for example, a computer arranged in a space different from the space 50. Specifically, the server apparatus 30 is provided outside the house, unlike the home of the user of the communication terminal 20.

As shown in FIG. 1, the server device 30 includes a control information generation unit 31 and a database 32. Hereinafter, each component of the server device 30 will be described in detail.

[Control information generator]
The control information generation unit 31 generates the lighting control information of each of the plurality of lighting fixtures 10 for bringing the current lighting information indicated by the lighting information close to the impression indicated by the impression information, based on the input information. In the present embodiment, the control information generation unit 31 generates illumination control information by referring to the database 32 based on the input information. Specifically, the control information generation unit 31 selects a dimming rate corresponding to an ideal lighting state from the database 32, and generates lighting control information based on the selected dimming rate.

In the present embodiment, the control information generation unit 31 grasps the current lighting state using basic information and lighting information included in the input information. Specifically, the control information generation unit 31 grasps the number of lighting fixtures 10 arranged in the space 50 and the arrangement thereof. Furthermore, the control information generation unit 31 extracts the color temperature and brightness (dimming rate) of the emitted light for each lighting fixture 10 arranged in the space 50 using the illumination information included in the input information. .

The illumination information includes, for example, an image of the space 50 (hereinafter referred to as “current image”). The control information generation unit 31 extracts the color temperature and brightness for each region by performing image processing on the current image.

For example, the control information generation unit 31 determines the areas of the ceiling 51, the floor 52, the wall 53, and the wall 54 from the current image. The control information generation unit 31 performs image processing such as edge detection or pattern matching on the current image, thereby determining each region of the ceiling 51, the floor 52, the wall 53, and the wall 54. The control information generation unit 31 extracts color temperature and brightness for each determined area. Since the control information generation unit 31 knows in which region each of the plurality of lighting fixtures 10 is arranged based on the layout information and the basic information, the color temperature and dimming currently set for each lighting fixture. The rate can be estimated.

In the present embodiment, the control information generation unit 31 extracts the color temperature and brightness of the ideal illumination state from the image included in the impression information (hereinafter referred to as “ideal image”). The control information generation unit 31 selects a dimming rate associated with a keyword corresponding to the color temperature and brightness extracted from the ideal image from the database 32. The control information generation unit 31 generates illumination control information based on the selected dimming rate and the extracted color temperature.

For example, the control information generation unit 31 extracts the color temperature and brightness by image processing for each region of the ideal image. Specifically, the control information generation unit 31 determines each area of the ceiling, floor, and wall from the ideal image. The specific processing is the same as the processing performed on the current image. Thereby, the control information generation part 31 can grasp | ascertain the color temperature and the brightness of the light from the lighting fixture provided in each of the ceiling in the ideal image, a floor, and a wall, for example.

For example, in the database 32, for each of a plurality of color temperatures, a dimming rate corresponding to each of a plurality of keywords is associated with each place in the space. The control information generation part 31 determines the light control rate according to each of the some lighting fixture 10 using layout information. Specifically, the control information generation unit 31 selects a combination of color temperature, brightness, and keyword that is most similar to the ideal image from the database 32 based on the color temperature and brightness of each region in the ideal image. To do. The control information generation unit 31 determines the color temperature and dimming rate of the emitted light from the plurality of lighting fixtures 10 arranged in the space 50 based on the selected combination. The control information generation unit 31 generates optimal illumination control information for lighting the plurality of lighting fixtures 10 with the determined color temperature and dimming rate.

At this time, the control information generation unit 31 adjusts the selected dimming rate within a range that can be realized with the performance indicated by the basic information. For example, it is assumed that a plurality of lighting fixtures 10 include lighting fixtures that cannot emit a sufficient amount of light. In this case, for example, the control information generation unit 31 generates illumination control information for increasing the dimming rate of the other lighting fixtures so that the other lighting fixtures compensate for the light flux that is insufficient for the lighting fixtures.

Further, for example, it is assumed that a plurality of lighting fixtures 10 include lighting fixtures that have a dimming function but do not have a toning function. In this case, the control information generation unit 31 generates illumination control information for setting the color temperature of another lighting fixture so that the color matching function that cannot be realized by the lighting fixture is supplemented by the other lighting fixture.

When the keyword (second keyword) is included in the impression information, the control information generation unit 31 responds to the difference in impression between the keyword (first keyword) in the database 32 and the second keyword included in the impression information. To adjust the selected dimming rate. Here, the first keyword is a keyword in the database 32 corresponding to the color temperature and brightness extracted from the ideal image. The control information generation unit 31 determines a weighting factor according to the impression difference, and adjusts the dimming rate by multiplying the selected dimming rate by the determined weighting factor.

[Database]
The database 32 is a database in which a plurality of color temperatures and a plurality of keywords (first keywords) indicating impressions of lighting conditions are associated with each other. In the database 32, a dimming rate corresponding to each of a plurality of keywords is associated with each of a plurality of color temperatures.

In the present embodiment, the database 32 includes a correspondence table of color temperature, keyword, and dimming rate for each combination of space type and size. The type of space is specifically “living room”, “dining room”, “bedroom”, and the like. The size of the space is, for example, the size of the room and the area of the room in the floor plan.

FIG. 7 is a diagram showing a part of the database 32 according to the present embodiment. Specifically, FIG. 7 shows a correspondence table corresponding to a living / dining room of 20 m ² to 30 m ² .

As shown in FIG. 7, in the database 32, a plurality of keywords are associated with each color temperature. Furthermore, a dimming rate corresponding to each of the plurality of lighting fixtures is associated with each of the plurality of keywords. The dimming rate at this time generally indicates the optimum brightness when an impression of the corresponding keyword is held at the corresponding color temperature.

Specifically, the brightness of light that feels “clean” differs for each color temperature. As shown in FIG. 7, the brightness of the light that feels “clean” is such that the lower the color temperature (ie, reddish light), the darker the color temperature is higher (ie, bluish light), bright. The same applies to “relaxation”. Thus, in the database 32, the optimal dimming rate is associated with each combination of color temperature and keyword.

In the example shown in FIG. 7, two keywords, “clean” and “relax”, are shown, but the present invention is not limited to this. For example, the two keywords are opposite sensitivity words among words having directionality based on a predetermined scale. For example, “clean” is the word with the highest awakening level, and “relaxing” is the word with the lowest awakening level. When an intermediate awakening degree keyword such as “slight relaxation” is acquired from the communication terminal 20, the control information generation unit 31 adjusts the “clean” dimming rate and the “relaxation” dimming according to the awakening degree. By interpolating (interpolating) the rate, the dimming rate corresponding to “slight relaxation” can be determined.

Thereby, when the color temperature and the keyword are acquired, the control information generation unit 31 can select the optimum dimming rate of each of the plurality of lighting fixtures. A detailed operation using the database 32 will be described later.

The database 32 is stored in a storage unit (not shown) provided in the server device 30. The storage unit is, for example, an HDD (Hard Disk Drive) or a flash memory. The server device 30 may not include the database 32. For example, the database 32 may be connected to the server device 30 via the network 40.

[Operation]
Subsequently, the operation of the lighting effect system 1 according to the present embodiment will be described with reference to FIG. FIG. 8 is a sequence diagram showing the operation of the lighting effect system 1 according to the present embodiment.

First, as shown in FIG. 8, the acquisition unit 21 of the communication terminal 20 acquires input information (S10). Specifically, the acquisition unit 21 acquires layout information, basic information, lighting information, and impression information based on a user operation. The acquisition unit 21 may acquire layout information and basic information stored in advance in a storage unit (not shown) of the communication terminal 20.

Next, the transmission unit 22 transmits the input information acquired by the acquisition unit 21 to the server device 30 (S20). The control information generation unit 31 of the server device 30 acquires the transmitted input information.

Next, the control information generation unit 31 generates illumination control information based on the acquired input information (S30). Specifically, the control information generation unit 31 generates illumination control information for realizing the illumination state desired by the user in the space 50 based on the input information. Details of this processing will be described later with reference to FIG.

The control information generation unit 31 transmits the generated illumination control information to the communication terminal 20 (S40). The receiving unit 23 of the communication terminal 20 receives the transmitted lighting control information.

Next, the transmission unit 22 of the communication terminal 20 transmits the illumination control information received by the reception unit 23 to each of the plurality of lighting fixtures 10 (S50). Each of the plurality of lighting fixtures 10 receives the lighting control information, and changes the lighting state according to the received lighting control information (S60). Specifically, each control unit 12 of the plurality of lighting fixtures 10 turns on the light source unit 11 with the color temperature and the dimming rate included in the illumination control information.

As described above, an illumination state corresponding to the illumination control information generated by the control information generation unit 31 can be realized in the space 50. Since the illumination control information is generated based on the ideal of the user, it is possible to realize an illumination state in which the space 50 is close to the ideal illumination state of the user.

Hereinafter, the details of the process of generating the illumination control information will be described with reference to FIG. FIG. 9 is a flowchart showing a process of generating illumination control information in the illumination effect system 1 according to the present embodiment.

As shown in FIG. 9, first, the control information generation unit 31 determines the characteristics of the space 50 (S31). The features of the space 50 include the nature of the space 50 and the number and arrangement of the plurality of lighting fixtures 10 arranged in the space 50.

Specifically, first, the control information generation unit 31 determines the type and size of the space 50 based on the layout information. For example, when the layout information shown in FIG. 3 is acquired, the control information generation unit 31 can grasp that the space 50 is a living / dining room of 20 m ² .

Furthermore, the control information generation unit 31 determines the arrangement and function of the plurality of lighting fixtures 10 based on the layout information and the basic information. For example, when the layout information illustrated in FIG. 3 and the basic information illustrated in FIG. 4 are acquired, the control information generation unit 31 includes four, one, and one illumination on the ceiling 51, the floor 52, and the wall 53 or the wall 54, respectively. It can be seen that the instrument 10 is arranged. It can also be seen that among the four luminaires 10a to 10d arranged on the ceiling 51, the two

luminaires

10b and 10d in the back do not have a toning function.

Next, the control information generation unit 31 determines the current lighting state (S32). For example, the control information generation unit 31 acquires an image (current image) captured from the space 50 and transmitted from the transmission unit 22 of the communication terminal 20 and determines the current lighting state based on the current image.

Specifically, the control information generation unit 31 first determines the areas of the ceiling 51, the floor 52, the wall 53, and the wall 54 from the current image. For example, the control information generation unit 31 performs image processing such as edge detection or pattern matching on the current image, thereby determining each region of the ceiling 51, the floor 52, the wall 53, and the wall 54.

The control information generation unit 31 extracts color temperature and brightness for each region. Thereby, since the color temperature and brightness of each of the ceiling 51, the floor 52, the wall 53, and the wall 54 are extracted, the control information generation unit 31 grasps the current lighting state by referring to the database 32. be able to. In the example shown in FIG. 7, it can be seen that the current illumination state is as follows, as indicated by the shading of the coarse dots.

That is, the lighting fixture on the ceiling 51 has a color temperature of 2000K, a dimming rate of 25%, and an impression on the relaxing side. The lighting fixture on the floor 52 has a color temperature of 2000K, a dimming rate of 25%, and an impression on the relaxing side. The lighting fixture of the wall 53 or the wall 54 has a color temperature of 3000K, a dimming rate of 50%, and an impression on the relaxing side.

Next, the control information generation unit 31 determines the illumination state of the ideal image (S33). For example, the control information generation unit 31 acquires an ideal image included in the impression information transmitted from the transmission unit 22 of the communication terminal 20 and determines the illumination state of the ideal image.

Specifically, the control information generation unit 31 first determines the areas of the ceiling, floor, and wall from the ideal image. For example, the image processing such as edge detection or pattern matching is performed on the ideal image to determine each area of the ceiling, floor, and wall.

The control information generation unit 31 extracts color temperature and brightness for each region. Thereby, since the color temperature and brightness of each of the ceiling, floor, and wall are extracted, the control information generation unit 31 can grasp the illumination state of the ideal image by referring to the database 32. In the example shown in FIG. 7, it can be seen that the illumination state of the ideal image is as follows, as indicated by the shading of dense dots.

That is, the lighting fixture on the ceiling has a color temperature of 5000K, a dimming rate of 75%, and the impression is on the relaxing side. The floor lighting fixture has a color temperature of 5000K, a dimming rate of 75%, and the impression is relaxed. The wall lighting fixture has a color temperature of 4000K, a dimming rate of 60%, and the impression is relaxed.

Next, the control information generation unit 31 determines whether or not a keyword is included in the impression information (S34). When the keyword is included (Yes in S34), the control information generation unit 31 estimates a sense of distance between the keyword and the keyword determined from the ideal image (S35). The sense of distance is a difference in impression between keywords, and specifically corresponds to a weighting coefficient used for weighting calculation.

For example, as shown in FIG. 7, the keyword determined from the ideal image is “relaxation”. At this time, when the keyword included in the impression information is “easy”, the control information generation unit 31 estimates a sense of distance between “relaxation” and “easy”. The sense of distance (weight coefficient) is determined by the ratio of the distance between “relaxation” and “easy” to the distance between “relaxation” and “clearness”. For example, the control information generation unit 31 estimates that “easy refreshing” indicates an impression of “refreshing” among “relaxing” and “refreshing”. For example, the control information generation unit 31 estimates that the weighting factor for “relaxation” is 1/3 and the weighting factor for “clean” is 2/3.

The control information generation unit 31 generates illumination control information based on the estimated sense of distance (S36). The control information generation unit 31 performs a weighting operation on the dimming rate associated with “clean” and the dimming rate associated with “relaxation” at the color temperature determined based on the ideal image. In FIG. 7, the numerical values used for the weighting calculation are shown enclosed in a square.

For example, for a lighting fixture on the ceiling, when the color temperature is 5000K, the dimming rate suitable for “clean” is 90%, and the dimming rate suitable for “relaxation” is 75%. Therefore, the dimming rate suitable for “slight relaxation” is 85% by weighting 90% (clean) with a weighting factor of 2/3 and 75% (relaxing) with a weighting factor of 1/3. It becomes. By performing the same calculation for the wall luminaire and the floor luminaire, the dimming rate of the wall luminaire is calculated as 73%, and the dimming rate of the floor luminaire is calculated as 85%.

Therefore, the control information generation unit 31 generates illumination control information for controlling the plurality of lighting fixtures 10 as follows. That is, the lighting fixture 10 on the ceiling 51 is turned on at a color temperature of 5000K and a dimming rate of 85%. The lighting fixture 10 on the floor 52 is lit at a color temperature of 5000K and a dimming rate of 85%. The lighting fixtures 10 on the

walls

53 and 54 are lit at a color temperature of 4000K and a dimming rate of 73%.

If no keyword is included (No in S34), the control information generation unit 31 generates illumination control information so as to bring the current illumination state closer to the illumination state of the ideal image (S36). For example, the control information generation unit 31 generates illumination control information that turns on the luminaire 10 with the color temperature and dimming rate of the ideal image.

When determining the dimming rate and color temperature, for example, the control information generation unit 31 may adjust the dimming rate and color temperature of the ideal image within a range that can be realized by the performance indicated by the basic information. Good.
