Structure

< integral Structure >

First, the configuration of the illumination system according to the embodiment will be described.

Fig. 1 is a block diagram showing a functional configuration of an illumination system 300 according to an embodiment.

The illumination system 300 is the following: the operation terminal 100 controls the lighting modes such as on/off (on or off), color, and/or light distribution of light emitted from the lighting fixture 200 disposed in a predetermined space such as a building. In the lighting system 300, the operation terminal 100 receives a selection of the color of light to be emitted from the lighting fixture 200 from the user.

The lighting system 300 includes the operation terminal 100 and the plurality of lighting fixtures 200.

The number of the lighting fixtures 200 included in the lighting system 300 may be one or a plurality of the lighting fixtures, and is not particularly limited.

The operation terminal 100 is an information terminal operated by a user. The operation terminal 100 is implemented by, for example, a smart phone or a tablet terminal. The operation terminal 100 is connected to each of the plurality of lighting fixtures 200 so as to be capable of wireless communication.

The operation terminal 100 may be implemented by a fixed personal computer or the like.

The operation terminal 100 includes a communication unit 110, a display unit 120, a reception unit 130, a storage unit 140, and an information processing unit 150.

The communication unit 110 is a communication interface for communicating with the lighting fixture 200. For example, the communication unit 110 is implemented by a communication module (communication circuit) for performing communication. The communication unit 110 is implemented by a communication module such as a wireless communication circuit, for example. The communication performed by the communication unit 110 is, for example, wireless communication, but may be wired communication. The communication standard used for communication is not particularly limited either.

The display unit 120 is a device for displaying an image such as a color panel. The display unit 120 is implemented by a display panel such as a liquid crystal panel or an organic EL (Electro Luminescence: electroluminescence) panel.

The color panel is an image (palette) configured with a plurality of colors and used to accept designation of colors from a user. Coordinate information corresponding to each color on the chromaticity diagram is set for each color of the color panel.

The receiving unit 130 is a device for receiving a user operation. The receiving unit 130 is implemented by a touch panel, a mouse, a keyboard, or the like, for example. In the present embodiment, the display unit 120 and the receiving unit 130 are integrally implemented by a touch panel display.

The storage unit 140 is a storage device capable of storing a computer program or the like executed by the information processing unit 150. The storage unit 140 is implemented by, for example, a semiconductor memory or the like. The storage unit 140 may be implemented by an HDD (Hard Disk Drive) or the like.

The information processing unit 150 is a processing unit that performs various processes executed by the operation terminal 100. The information processing section 150 is implemented by a microcomputer, for example, but may be implemented by a processor. The functions of the information processing unit 150 are realized by executing a computer program stored in the storage unit 140 by, for example, a microcomputer, a processor, or the like constituting the information processing unit 150.

The information processing unit 150 includes, for example, an acquisition unit 151, a first control unit 152, a second control unit 153, and a setting unit 154.

The acquisition unit 151 is a processing unit that acquires various information such as color information. For example, the acquisition unit 151 acquires various information such as color information via the communication unit 110.

The color information is information indicating a color selected by a user among a plurality of colors arranged in the color panel. The acquisition section 151 acquires color information indicating a color selected by a user among a plurality of colors arranged in a color panel. That is, the color information is information indicating a color selected by the user, which is received by the receiving unit 130.

The first control unit 152 is a processing unit that controls the display of the display unit 120 (specifically, the image displayed on the display unit 120). More specifically, the first control unit 152 causes the display unit 120 to display a color panel in which different colors are arranged in each of a plurality of areas arranged in a matrix. In the present embodiment, each of the plurality of regions is rectangular (rectangular region 540 (see fig. 3)).

In the present embodiment, the first control unit 152 causes the display unit 120 to display one of the representative color panel 500 (see fig. 3) and the detailed color panel 510 (see fig. 4) in a switchable manner, and the representative color panel 500 and the detailed color panel 510 are color panels in which different colors are arranged in each of a plurality of areas (for example, rectangular areas 540) arranged in a matrix. In the present embodiment, the acquisition unit 151 acquires color information indicating a color selected by the user among a plurality of colors arranged in at least one of the representative color panel 500 and the detailed color panel 510.

The arrangement of the colors in a matrix means that the colors are arranged in a first direction D1 and a second direction D2 (see fig. 3, in other words, vertically and horizontally) which will be described later, and the number of colors arranged in the vertical direction and/or the number of colors arranged in the horizontal direction may be the same or different in each column and/or each row.

The representative color panel 500 is an example of a color panel, and is an image for displaying colors that divide hues and chroma in chromaticity coordinates and are respectively assigned to each rectangular region arranged in the first direction D1 and the second direction D2.

The detailed color panel 510 is an example of a color panel, and is an image for displaying colors that are divided into hue and chroma in chromaticity coordinates more finely than the representative color panel 500 and are respectively assigned to each rectangular region arranged in the first direction D1 and the second direction D2.

In the following description, the content of the description may be applied to the representative color panel 500 or the detailed color panel 510 in the case of describing the color panel.

The second control unit 153 is a processing unit that controls the lighting apparatus 200. Specifically, the second control unit 153 controls the lighting system of the lighting apparatus 200. More specifically, the second control unit 153 controls the lighting fixture 200 so that the lighting fixture 200 emits light having a color indicated by the color information. For example, the second control unit 153 controls the lighting fixture 200 so that the lighting fixture 200 emits light of a color indicated by the color information.

For example, the second control unit 153 transmits chromaticity coordinates of a color selected by the user from the color panel to the lighting fixture 200 as a control value, thereby controlling the lighting system of the lighting fixture 200.

The setting unit 154 is a processing unit that stores information indicating the lighting fixture 200 (specifically, fixture identification information uniquely indicating the lighting fixture 200) in association with color information (that is, information indicating a color selected by a user in correspondence with the lighting fixture 200) in the storage unit 140.

As described above, the operation terminal 100 displays the color panel, and stores the selection result of the lighting fixture 200 received from the user in association with the selection result of the color. The operation terminal 100 controls the lighting system of the lighting fixture 200 such that, for example, the lighting fixture 200 emits light of a color associated with the lighting fixture 200 at a time designated by a user. The time is not particularly limited, and may be any. The time may be set by a timer or the like when the receiving unit 130 receives an instruction to cause the lighting fixture 200 to emit light, for example. For example, the second control unit 153 may control the lighting fixture 200 so that the lighting fixture 200 is turned on in the color indicated by the color information when the acquisition unit 151 acquires the color information. Specifically, the second control unit 153 may control the lighting fixture 200 so that the lighting fixture 200 is immediately turned on in the color indicated by the color information when the acquisition unit 151 acquires the color information. The second control unit 153 may switch whether to control the lighting fixture 200 so that the lighting fixture 200 is immediately turned on in the color indicated by the color information when the acquisition unit 151 acquires the color information, based on the lighting information indicating whether to immediately turn on the lighting fixture 200 in the color indicated by the color information. For example, the acquisition unit 151 acquires the lighting information based on whether or not the user inputs via the reception unit 130 that the lighting fixture 200 is immediately lighted with the color indicated by the color information.

In addition, there are the following cases: the lighting fixture 200 includes a plurality of light sources that can be individually controlled. In this case, the second control unit 153 controls each of the plurality of light sources so that each of the plurality of light sources emits light of the color indicated by the color information for each of the plurality of light sources based on the color information indicating the color of each of the plurality of light sources. In this case, for example, the acquisition unit 151 acquires color information indicating the color of each of the plurality of light sources from the user via the reception unit 130. For example, in the case where the lighting fixture 200 includes a plurality of light sources that can be controlled independently, such as a light source that emits light upward Fang Shechu and a light source that emits light downward, the color of each light source is set by the user when the light sources are controlled in a centralized manner.

The second control unit 153 controls the lighting fixture 200 such that the lighting fixture 200 emits light of a color indicated by the color information, for example. Here, the second control unit 153 may control the lighting fixture 200 based on the structural information indicating at least any one of the color, the irregularities, and the material of the surface of the structure so that the surface appears to have the same color as the color indicated by the color information when the light emitted from the lighting fixture 200 is irradiated to the surface. In this case, for example, the acquisition unit 151 acquires the structure information from the user via the reception unit 130. When the lighting fixture 200 (color fixture) capable of emitting light of a plurality of colors emits light, the color of the irradiation surface appears to be different depending on the color or the unevenness of the irradiation surface. For example, in order to make the entire wall look the same color using a plurality of lighting fixtures 200, it is sometimes necessary to adjust the color of light emitted from each lighting fixture 200. Accordingly, the second control portion 153 adjusts the control value of the color assignment in the color panel for each lighting fixture 200, for example, based on the configuration information.

The operation terminal 100 may further include a timer such as an RTC (Real Time Clock) to measure Time and/or acquire date and Time information described later. The operation terminal 100 may acquire time (for example, date and time information) by communicating with an external server or the like.

For example, various information acquired from a user or the like may be acquired from the server device via the communication unit 110, or may be acquired from the storage unit 140 when the information is stored in the storage unit 140 in advance.

The lighting fixture 200 is a lighting fixture capable of wirelessly communicating with the operation terminal 100 and emitting light. In the present embodiment, the lighting fixture 200 includes a red LED (Light Emitting Diode: light emitting diode) that emits red light, a blue LED that emits blue light, and a green LED that emits green light.

For example, the lighting fixture 200 may include a plurality of white LEDs that emit white light having different color temperatures. That is, the lighting fixture 200 may be a lighting fixture in which the color temperature of the emitted light is variable.

The plurality of lighting fixtures 200 may be lighting fixtures having the same functions as each other or may be lighting fixtures having different functions from each other (for example, different lighting systems that can be adopted such as different colors of light emitted).

< acceptance of color selection >

Next, a process of accepting a user selection of a color will be described.

Fig. 2 to 5 are diagrams each showing a specific example of an image displayed on the display unit 120. Specifically, fig. 2 is a diagram showing a setting image 400 according to the embodiment. Fig. 3 is a diagram showing a representative color panel image 410 according to the embodiment. Fig. 4 is a diagram showing a detailed color panel image 420 according to the embodiment. Fig. 5 is a diagram showing a map image 440 according to the embodiment.

The first control unit 152 causes the display unit 120 to display any one of the setting image 400, the representative color panel image 410, the detailed color panel image 420, and the map image 440, for example, based on the instruction received by the reception unit 130 from the user.

For example, when a mark of any one of the plurality of pens corresponding to the plurality of lighting fixtures 200 included in the setting image 400 is tapped by the user, the first control section 152 causes the display section 120 to display the representative color panel image 410. In addition, for example, when the "select from all colors" button included in the representative color panel image 410 is tapped by the user, the first control section 152 causes the detailed color panel image 420 to be displayed on the display section 120. Further, for example, when the "decision" button included in the detailed color panel image 420 is tapped, the first control section 152 causes the display section 120 to display the representative color panel image 410. In addition, for example, when the "decision" button included in the representative color panel image 410 is tapped by the user, the first control section 152 causes the setting image 400 to be displayed on the display section 120. At this time, for example, the setting unit 154 stores the color selected by the user in the storage unit 140 in association with appliance information indicating the lighting appliance 200 (the lighting appliance 200 corresponding to the mark of the pen tapped by the user).

As shown in fig. 2, the setting image 400 is an image for displaying information (setting information 580) related to the luminaire 200. For example, the storage unit 140 stores appliance information uniquely indicating each of the plurality of lighting appliances 200. The setting unit 154 stores, for example, lighting system information indicating lighting systems of the plurality of lighting fixtures 200 in association with the fixture information in the storage unit 140 based on the input from the user received by the receiving unit 130. The first control unit 152 causes the display unit 120 to display a setting image 400 including setting information 580 indicating the appliance information, the lighting system information, and the like stored in the storage unit 140. Specifically, the first control unit 152 causes the display unit 120 to display a scene name indicating the lighting system (scene) of the lighting fixture 200, the color of the light emitted from the lighting fixture 200 in the lighting system, and the identification information 570 set for the color. By displaying the setting image 400, the user can confirm the number (color number) and color set for the scene together with the scene name in the lighting fixture 200 in which the lighting state is defined. For example, in the scene name display section 581 shown in fig. 2, the scene name is displayed like "scene 1" or "scene 2". For example, the set color display section 582 shown in fig. 2 displays the color of light as "5000K" or the like. For example, in the identification information display unit 583 shown in fig. 2, the identification information 570 is displayed as "h03" or the like. As shown in fig. 2, for example, a color corresponding to "h03" is displayed on the setting color display section 582 adjacent to "h 03". Thus, the information indicating the color may be displayed by a character or the like, or may be displayed by a color. Details of the numbering will be described later.

The scene information is information for defining a lighting pattern (lighting state). For example, the user operates the operation terminal 100 to designate arbitrary scene information, thereby setting the lighting fixture 200 to a desired lighting state. The scene information is transmitted to the lighting fixture 200 when the user operates the operation terminal 100 to designate arbitrary scene information, for example.

The user selects (e.g., touches) an icon or the like representing a desired lighting fixture 200 displayed on the display unit 120 by operating the operation terminal 100 on which the setting image 400 is displayed, for example, so that the desired lighting fixture 200 emits light of a desired color. For example, when the reception unit 130 receives the selection, the first control unit 152 causes the display unit 120 to display the representative color panel image 410.

As shown in fig. 3, the representative color panel image 410 is an image for displaying the representative color panel 500.

The user selects a desired color from among a plurality of colors configured in the representative color panel 500. Thereby, the setting unit 154 stores color information indicating the color selected by the user in the storage unit 140 in association with appliance information indicating the lighting appliance selected by the user.

Here, for example, it is assumed that the user wants to select a color from colors other than the colors arranged in the representative color panel 500. In this case, for example, the user selects a button (icon) displayed as "select from all colors". For example, when the reception unit 130 receives the selection, the first control unit 152 causes the display unit 120 to display the detailed color panel image 420.

As shown in fig. 4, the detailed color panel image 420 is an image for displaying the detailed color panel 510.

As shown in fig. 3 and 4, the number of colors (included) configured in the representative color panel 500 is smaller than the number of colors configured in the detailed color panel 510.

The number of colors arranged in the detailed color panel 510 and the number of colors arranged in the representative color panel 500 are not particularly limited as long as the number of colors arranged in the representative color panel 500 is smaller than the number of colors arranged in the detailed color panel 510.

For example, the first control unit 152 causes the display unit 120 to display identification information 570 including at least one of a character (character string) and a symbol uniquely representing each of a plurality of colors arranged in the color panel, together with the color panel.

For example, the first control unit 152 causes the display unit 120 to display the identification information 570 so as to correspond to a plurality of rows and a plurality of columns of a plurality of areas (for example, rectangular areas 540) arranged in a matrix. Specifically, for example, the first control unit 152 displays the respective rows of numerals of the plurality of rectangular areas 540 as identification information on the display unit 120 together with the detailed color panel image 420 so as to correspond to the detailed color panel 510, and displays the respective columns of letters as identification information on the display unit 120 together with the detailed color panel image 420. For example, the first control unit 152 causes the display unit 120 to display the serial numbers of the rows and columns of the plurality of rectangular areas and/or the arbitrary determined names of the detailed color panel 510 or the representative color panel 500 and the detailed color panel 510. For example, the first control unit 152 causes the display unit 120 to display the identification information 570 so as to overlap with each color of the representative color panel 500.

The identification information may be any symbol or the like that is set as long as it uniquely indicates each color. In the present embodiment, the identification information is a number (character or number) uniquely representing each of a plurality of colors arranged in the color panel. For example, the first control unit 152 assigns a number to each color panel to the detailed color panel 510 or the representative color panel 500 and the detailed color panel 510, and displays the assigned number together with the color panel.

For example, the user inputs a number (identification information 570) indicating a desired color to the selected color number receiving unit 600. Thus, for example, the acquisition unit 151 acquires, as the color information, identification information 570 indicating any one of a plurality of colors among identification information 570 uniquely indicating each of the plurality of colors arranged in the color panel (for example, the detailed color panel 510). That is, color numbers are assigned to the respective colors in advance, and the assigned color numbers are input, so that the color corresponding to the input color number in the color panel (for example, both the representative color panel 500 and the detailed color panel 510) is brought into a state selected by the user.

Here, for example, when the color panel (for example, both the detailed color panel 510 and the representative color panel 500) is displayed on the display unit 120, the first control unit 152 causes the display unit 120 to display information indicating that the color indicated by the color information is selected (for example, the selected color display unit 590). The selected color display 590 displays, for example, a color indicated by color information. In this way, the first control unit 152 causes the identification information 570 indicating the color indicated by the color information to be displayed on the outside of the color panel in the display unit 120. Specifically, the first control unit 152 causes the color currently selected by the user to be displayed outside the frame of the representative color panel 500 or the detailed color panel 510 in the display unit 120 in a character or graphic or the like.

For example, an instruction to switch the display of the color panel to the detailed color panel 510 is input by the user in a state where the color is selected in the representative color panel 500. In this case, for example, the first control unit 152 causes the display unit 120 to display information indicating the selected color and the detailed color panel 510. That is, for example, when the color information is acquired by the acquisition unit 151 in a state in which the representative color panel 500 is displayed on the display unit 120, the first control unit 152 switches the display of the display unit 120 from the display of the representative color panel 500 to the display of the color information and the display of the detailed color panel 510. Similarly, for example, in a state where the user selects a color in the detailed color panel 510, an instruction to switch the display of the color panel to the representative color panel 500 is input. In this case, the first control unit 152 may cause the display unit 120 to display information indicating the selected color and the representative color panel 500. In this way, the display of the display unit 120 may be shifted from the representative color panel image 410 to the detailed color panel image 420 while maintaining the information of the color selected by the user. For example, the initial color selected by the user at the time of image migration becomes the color selected by the user in the image before migration.

The detailed color panel 510 may be set so as not to be displayed on the display unit 120. For example, when the acquisition unit 151 acquires display information indicating whether or not to display the detailed color panel 510 from the user via the reception unit 130, the first control unit 152 switches whether or not to display the detailed color panel 510 based on the display information. The setting image 400 or the representative color panel image 410 may include a button or the like for receiving display information. For example, the first control unit 152 may not cause the display unit 120 to display a button (image) of "select from all colors" included in the representative color panel image 410 for switching the display of the display unit 120 to the detailed color panel image 420.

For example, the first control unit 152 may change the identification information indicating any one of the plurality of colors arranged in the color panel to the character string acquired by the acquisition unit 151 and display the character string on the display unit 120. That is, the color number may be set to an arbitrary character string desired by the user. For example, the acquisition unit 151 acquires the character string from the user via the reception unit 130. The setting image 400, the representative color panel image 410, or the detailed color panel image 420 may include a display for receiving the character string.

Further, for example, the first control unit 152 causes the display unit 120 to display operation buttons 560 for receiving input from the user. The operation button 560 is a button for a user to operate when selecting a color.

For example, when the acquisition unit 151 acquires color information, the setting unit 154 may store information indicating (vi) a color having the same color hue as that indicated by the color information and different in chroma, or (vii) a color having the same color chroma as that indicated by the color information and different in hue in the storage unit 140 in association with information indicating another lighting fixture 200 different from the lighting fixture 200. For example, information indicating other lighting fixtures 200 associated with color information according to the color information associated with the lighting fixture 200 is acquired from the user via the reception unit 130. For example, in the plurality of lighting fixtures 200 that operate in conjunction with each other, when a color is selected for some of the plurality of lighting fixtures 200, a color that is equal to the selected color hue and different in chroma, or a color that is equal to the selected color chroma and different in hue is automatically set as the color for the other lighting fixtures 200. For example, the colors at the same position in the second direction D2 (in other words, the colors aligned in the first direction D1) are colors having the same hue and different chroma. For example, the colors at the same position in the first direction D1 (in other words, the colors aligned in a line in the second direction D2) are colors having equal saturation and different hues. For example, when light is emitted to the wall surface in a gradual manner by two lighting fixtures of one lighting fixture 200 and the other lighting fixtures 200, which are different from each other in light distribution angle, the color of one lighting fixture 200 is automatically selected when the color of the other lighting fixture 200 is selected. The color to be automatically selected may be any color having the same hue as the selected color and different from each other, or may be any color having the same hue and different from each other. The combination of the lighting fixtures 200 whose colors are automatically set in this way may be determined arbitrarily in advance.

As shown in fig. 5, the map image 440 is an image representing a map of a place where the lighting fixture 200 is disposed. The user selects, for example, an icon (e.g., appliance icon 520) representing the lighting appliance 200 included in the map image 440. In this case, for example, the second control unit 153 performs control to turn on the lighting fixture 200.

Here, for example, the first control unit 152 causes the display unit 120 to display a map (map image 440) in which the appliance icon 520 indicating the lighting appliance 200 and the explanatory text 530 (information indicating the state of the lighting appliance 200, such as the color temperature of the light emitted from the lighting appliance 200) are superimposed. At this time, for example, the first control unit 152 displays the color of the appliance icon 520 and the color of the explanatory character 530 on the display unit 120 in the color indicated by the color information (specifically, the color information associated with the appliance information indicating the lighting appliance 200 corresponding to the appliance icon 520).

The first control unit 152 may display information indicating the color of the light currently emitted from the lighting fixture 200 on the display unit 120 based on the state information indicating the current lighting system of the lighting fixture 200. In fig. 5, for example, information indicating the color of light currently emitted from the lighting fixture 200 is displayed as "6500K".

For example, the status information is acquired from the lighting fixture 200 via the communication section 110. The information indicating the color of the light currently emitted from the lighting fixture 200 may be included in the setting image 400, the representative color panel image 410, the detailed color panel image 420, the map image 440, or another image other than these images. For example, the first control unit 152 causes the display unit 120 to display a color closest to the color of the light currently emitted from the lighting fixture 200 and/or a color number of the color, based on the status information acquired from the lighting fixture 200 by the acquisition unit 151 via the communication unit 110.

Fig. 6 is a diagram showing a detailed color panel image 421 according to a modification of the embodiment.

In the modification, the operation terminal 100 receives color fade information from the user.

The color-fade information is information indicating the color at the time of fading in and fading out the color of the light emitted from the lighting fixture 200.

For example, the detailed color panel image 421 is provided with a selection color number receiving unit 600 for receiving a color at the start and a color at the end of the fade-in fade-out of the color of the light emitted from the lighting fixture 200.

For example, when the acquisition unit 151 acquires color fade information indicating the color of the start point of the color fade and the color of the end point of the color fade, the second control unit 153 controls the illumination appliance 200 so that the color of the emitted light changes from the color of the start point to the color of the end point based on the color fade information. In this way, for example, the user can define a scene (specifically, a change in lighting system) having a variation in color such as blue sky→gamer sky by setting the start point and the end point of the fade-in fade-out of the color of the lighting fixture 200.

Here, the color fade-in and fade-out information may include information indicating a color of a relay point set between a color of the start point and a color of the end point. In this case, for example, the second control unit 153 controls the lighting fixture 200 so that the color of the emitted light changes from the color of the start point to the color of the end point via the color of the relay point based on the color fade information. That is, the user may set a point through which the color of the lighting fixture 200 fades in and out, in addition to the start point and the end point. For example, the state of the color migrates as follows: the color changes on lines in the chromaticity diagram, each of which is obtained by connecting a start point, a relay point, and an end point with a straight line.

Further, for example, the first control unit 152 causes the display unit 120 to display the color based on the color fade information (the gradually changing color as displayed on the color fade display unit 550) gradually so as to change from the color of the start point to the color of the end point continuously. For example, the color to be displayed is displayed such that the color changes on a line in which the start point, the intermediate point, and the end point are connected by a straight line in the chromaticity diagram.

Further, these displays related to the color fades may also be made in the representative color panel image 410.

The detailed color panel image 421 may be provided with a selected color number receiving unit 600 for receiving the color of the relay point.

< setting of color Panel >

Next, a method for setting the colors arranged in the color panel will be described.

The plurality of colors arranged in the representative color panel 500 and the detailed color panel 510 are predetermined, for example. For example, the first control unit 152 causes the plurality of colors arranged in the color panel to be arranged in the first direction D1 on the surface of the display unit 120 (that is, in the screen of the display unit 120) in the saturation order and to be displayed on the display unit 120 in the hue order in the second direction D2 orthogonal to the first direction D1 on the surface of the display unit 120. In addition, the plurality of colors arranged in the color panel are set such that the higher the saturation, the larger the color difference of the hues adjacent in the second direction D2 (that is, the difference of the colors in the second direction D2). Specifically, for example, the first control unit 152 causes the display unit 120 to display a plurality of colors arranged in at least one of the representative color panel 500 and the detailed color panel 510 in such a manner that the colors are arranged in the at least one color panel in the color saturation order in the first direction D1 and in the hue order in the second direction D2 orthogonal to the first direction D1. Further, the plurality of colors arranged in the one color panel are set such that at least one of a color difference in hue adjacent in the second direction D2 and a color difference between the adjacent colors in the first direction D1 (that is, a difference in color in the first direction D1) is larger as the chroma is higher.

Fig. 7 is a diagram for explaining chroma and hue. Specifically, fig. 7 is a chromaticity diagram (xy chromaticity diagram) for explaining changes in chroma and color phase.

The chroma increases as going outward from a white region (a region containing white surrounded by a dot-dash line in fig. 7) located at the center of the chromaticity diagram.

In addition, the hue varies in a direction around the outer periphery of the chromaticity diagram.

Fig. 8 is a diagram for explaining colors arranged in a color panel. Specifically, fig. 8 is a chromaticity diagram (u 'v' chromaticity diagram) for explaining colors arranged in the color panel.

The lighting fixture 200 includes, for example, a blue LED that emits blue light (light of the color of the blue dot in fig. 7 and 8), a green LED that emits green light (light of the color of the green dot in fig. 7 and 8), and a red LED that emits red light (light of the color of the red dot in fig. 7 and 8). In this case, the lighting fixture 200 can emit light of a color of a region (an illuminable region) shown by a dotted line in fig. 7 and 8 by controlling the intensity (light amount) of light emitted from each LED. As for the color panel for the user to select the color of such light emitted from the lighting fixture 200, for example, a plurality of line segments (straight lines) are drawn so as to go from the white point at the center of the white region to the broken line indicating the illuminable region. Since the line segments have a substantially fixed hue, the user can select a color with a fixed hue impression. A plurality of extraction points are extracted at predetermined intervals from each of the plurality of line segments. The colors of the plurality of extraction points extracted in this way are arranged on the color panel. The plurality of line segments are radially provided from the white point, and a plurality of extraction points are extracted at predetermined intervals from each of the plurality of line segments, whereby the farther the extraction points are from the white point, that is, the higher the chroma, the wider the distance between adjacent colors. Thus, the plurality of colors arranged in the color panel are set so that the higher the chroma, the larger the chromatic aberration of the adjacent hues in the second direction D2. On the other hand, the lower the saturation of the plurality of colors arranged in the color panel is, the smaller the distance between the plurality of colors and the adjacent color in the second direction D2 is.

As shown in fig. 8, for example, a radial line segment centered on the white point is used, whereby the extraction point on the line segment is a substantially fixed hue, and the extraction point is determined to be lower in chroma as approaching the white point and higher in chroma as separating from the white point.

The number of the plurality of line segments and the intervals between the line segments, the number of the extraction points to be extracted, and the predetermined intervals may be arbitrarily determined. For example, the first control unit 152 may determine the color arranged in the color panel based on the information acquired from the user by the acquisition unit 151 via the reception unit 130 and the information indicating the color of the light that can be emitted from the lighting fixture 200.

The number of extraction points extracted on each line segment is, for example, the same number on each line segment, but may be different.

The predetermined intervals may be the same or different for each line segment.

The predetermined interval may be a fixed interval, or may be set so that the interval becomes shorter as the interval gets closer to the white region and so that the interval becomes longer as the interval gets farther from the white region.

For example, the first control unit 152 may display on the display unit 120 a color panel in which a plurality of colors are arranged in the first direction D1 on the surface of the display unit 120 in the order of saturation and in the second direction D2 orthogonal to the first direction D1 on the surface of the display unit 120 in the order of hue, and red, blue, and green are arranged as the colors of light that can be emitted from the lighting fixture 200.

Here, the red, blue, and green are, for example, colors of light emitted from LEDs included in the lighting fixture 200. For example, red is the color of red light emitted from a red LED included in the lighting fixture 200 (for example, the color of light having the center wavelength of the light). For example, the green color is a color of green light emitted from a green LED included in the lighting fixture 200 (for example, a color of light having a center wavelength of the light). For example, blue is a color of blue light emitted from a blue LED included in the lighting fixture 200 (for example, a color of light having a center wavelength of the light). For example, in the color panel, the colors are configured based on specification information of the lighting fixture 200.

The colors of red, blue, and green may be predetermined colors and may be arranged on the color panel.

The specification information is information indicating the performance of the lighting fixture 200, such as a color that the lighting fixture 200 can emit. For example, the acquisition unit 151 acquires specification information via the communication unit 110 by communicating with the lighting fixture 200.

The specification information may be stored in the storage unit 140 in advance.

For example, the first control unit 152 changes the color arranged in the color panel so that the color of the light which the lighting fixture 200 cannot emit is not arranged in the color panel, based on the specification information indicating the color of the light which the lighting fixture 200 can emit; (ii) The color panel displayed on the display unit 120 is changed to a color panel in which the color of the light that cannot be emitted by the lighting fixture 200 is not arranged, among a plurality of color panels in which at least a part of the arranged colors are different; or (iii) append the color of light that the luminaire 200 is capable of emitting to a color panel. That is, the first control unit 152 does not display the color that cannot be lighted on the display unit 120 through the color panel based on the specification information of the lighting fixture 200 that is the control target. For example, when the color range that can be lighted differs depending on the lighting fixture 200, the first control unit 152 determines the color disposed in the color panel based on the product number that is one example of the specification information determined for each lighting fixture 200.

The plurality of color panels are, for example, detailed color panels 510 in which at least some of the colors are different from each other. The representative color panel 500 and the detailed color panel 510 may be provided in plurality, respectively. The information of these color panels may be stored in the storage unit 140 in advance. The display unit 120 displays these multiple color panels in a switchable manner, for example. For example, when a user selects an arbitrary color from among the colors arranged in one of the representative color panel 500 and the detailed color panel 510, the first control unit 152 may select a color panel from among a plurality of color panels in the other of the representative color panel 500 and the detailed color panel 510 based on the arbitrary color, and cause the display unit 120 to display the selected color panel.

In addition, for example, when the acquisition unit 151 acquires color information when the detailed color panel 510 is displayed on the display unit 120, the first control unit 152 configures the color indicated by the color information to the representative color panel 500. That is, the color selected in the detailed color panel 510 may also be reflected in such a manner that the color is configured to the representative color panel 500.

Further, for example, the first control unit 152 causes the display unit 120 to display any one of a plurality of color panels having at least some different colors among the disposed colors, based on an operation history of the user operating the illumination system 300 (more specifically, an operation history of the operation terminal 100). For example, the first control unit 152 causes the display unit 120 to preferentially display a color panel including a color most frequently selected by the user among the plurality of color panels. In this way, for example, the first control unit 152 changes a part of the colors of the representative color panel 500 or the detailed color panel 510 according to the operation history of the user operating the operation terminal 100. Alternatively, for example, the first control unit 152 determines the color panel displayed on the display unit 120 from among the plurality of color panels based on the operation history of the user operating the operation terminal 100. Alternatively, for example, the first control unit 152 causes information (for example, a color selected in the past) indicating the operation history to be displayed on the outside of the color panel in the display unit 120, based on the operation history of the user operating the operation terminal 100.

Further, for example, the first control unit 152 causes the display unit 120 to display any one of a plurality of color panels having at least some of the colors arranged different from each other, based on the date and time information.

The date and time information is, for example, information indicating the current time when the user operates the operation terminal 100. The first control unit 152 selects, for example, a color panel that is preferentially displayed on the display unit 120 according to time, date, season, or the like, from among the plurality of color panels, for example, a color panel that includes a lot of colors having high chroma in the daytime, a color panel that includes a lot of colors having low chroma in the nighttime, a color panel that includes a lot of colors of the cold color system in the summer, a color panel that includes a lot of colors of the warm color system in the winter, or the like. For example, the first control unit 152 causes the display unit 120 to display the color (for example, a plurality of colors of the green series) selected in this way as the recommended color in the leftmost column of the color panel.

For example, the first control unit 152 may determine the color to be arranged in the color panel based on the information acquired by the acquisition unit 151, such as the information acquired from the user via the reception unit 130.

For example, the first control unit 152 divides the chromaticity diagram into a plurality of areas based on division number information indicating the division number, determines a plurality of colors arranged in the color panel based on the plurality of areas, and causes the display unit 120 to display the color panel on which the determined plurality of colors are arranged. For example, the acquisition unit 151 acquires the division number information from the user via the reception unit 130. That is, the number of divisions of chromaticity coordinates in the color panel may also be arbitrarily set by the user.

Fig. 9 is a diagram for explaining an example of a user's selection of colors arranged in a color panel. Specifically, fig. 9 is a diagram showing a chromaticity diagram image 430 displayed on the display unit 120 when a selection of a color arranged in the color panel is received from the user.

The chromaticity diagram image 430 is an image containing chromaticity diagrams. For example, the first control unit 152 causes the display unit 120 to display the chromaticity diagram image 430 so as to receive a designation of a color arranged in the color panel from the user. For example, the first control unit 152 causes the display unit 120 to display the setting image 400 including the button for causing the chromaticity diagram image 430 to be displayed on the display unit 120. For example, when the button is tapped by the user, the first control unit 152 causes the chromaticity diagram image 430 to be displayed on the display unit 120.

The user inputs color range information indicating a range of colors by drawing on a chromaticity diagram in the chromaticity diagram image 430 with a finger, for example. And, the user also inputs the division number information. The acquisition unit 151 acquires these pieces of information, and the first control unit 152 divides the range indicated by the color range information by the division number indicated by the division number information, and arranges a plurality of colors determined by the division on the color panel. In the example shown in fig. 9, for example, the first control unit 152 extracts the number of colors indicated by the divided number information on the line indicated by the broken line at predetermined intervals, and arranges the extracted colors on the color panel.

The first control unit 152 may extract the colors at equal intervals based on the division number information, for example, may extract the colors at shorter intervals as the chroma is lower than in the case of the chroma being higher.

Alternatively, information indicating the interval may be acquired from the user, and the interval may be determined based on the information.

For example, when the first control unit 152 causes the display unit 120 to display a chromaticity diagram (chromaticity diagram image 430) and the acquisition unit 151 acquires color selection information indicating two points in the chromaticity diagram displayed on the display unit 120, the first control unit 152 extracts colors on a straight line connecting the two points in the chromaticity diagram at predetermined intervals and arranges the extracted colors on the color panel. That is, the color on the straight line between any two points selected on the chromaticity diagram is reflected to the color panel.

For example, the user inputs the first point and the second point as shown in fig. 10 by tapping (selecting) a desired position (color) of the chromaticity diagram displayed on the display section 120. In this case, for example, the first control unit 152 extracts colors on a straight line connecting the first point and the second point at predetermined intervals, and arranges the extracted colors on the color panel.

For example, when the acquisition unit 151 acquires color selection information indicating one point in the chromaticity diagram displayed on the display unit 120, the first control unit 152 extracts a color on a straight line connecting the one point in the chromaticity diagram and a predetermined white point indicating white in the chromaticity diagram at a predetermined interval, and places the extracted color on the color panel. That is, the color on the straight line between any one point selected on the chromaticity diagram and the predetermined white point is reflected on a part of the color panel.

For example, the user inputs the first point as shown in fig. 10 as described above. In this case, for example, the first control unit 152 extracts colors on a straight line connecting the first point and the white point at predetermined intervals, and arranges the extracted colors on the color panel.

The chromaticity coordinates of the white point are stored in the storage unit 140 in advance, for example.

For example, when the acquisition unit 151 acquires color selection information indicating two points in the chromaticity diagram displayed on the display unit 120, the first control unit 152 creates a circle centered on one of the two points and having a radius from the one point to the other of the two points, creates a plurality of line segments from the one point to the circle provided at predetermined rotation angles with the one point as a rotation center, extracts colors on at least one line segment in the plurality of line segments in the chromaticity diagram at predetermined intervals, and arranges the extracted colors on the color panel. That is, a circle is created with a radius around any one point selected on the chromaticity diagram and with a distance from the one point to any one point selected differently from the one point, a plurality of straight lines are radially generated at predetermined angles, colors on the straight lines are extracted, and colors on at least one straight line among the straight lines are reflected on a part of the color panel.

For example, the user inputs the first point and the second point as shown in fig. 10 as described above. In this case, for example, the first control unit 152 creates a circle centered at the first point and having a radius from the first point to the second point. Next, the first control unit 152 creates a plurality of line segments from the first point to the circle, which are provided at predetermined rotation angles with the first point as the rotation center. In fig. 10, the line segment is shown with 6 broken lines. Next, the first control unit 152 extracts colors on each line segment in the chromaticity diagram at predetermined intervals, and arranges the extracted colors on the color panel.

The color determined based on the operation history, date and time information, and the like may be replaced with the color already arranged in the color panel, and the color specified by the user may be additionally arranged on the color already arranged in the color panel. When a new color is arranged on the color panel, the first control unit 152 may rearrange the colors arranged on the color panel so that the colors are arranged in the color panel in the first direction D1 in the saturation order and in the second direction D2 orthogonal to the first direction D1 in the hue order for a plurality of colors arranged on the panel. Alternatively, when a new color is arranged on the color panel, the first control unit 152 may be arranged on the color panel so as to add a row or a column of the new color.

[ procedure ]

Next, the processing performed by the operation terminal 100 will be described.

Fig. 11 is a flowchart for explaining a processing procedure of the operation terminal 100 according to the embodiment.

First, the first control unit 152 causes the display unit 120 to display a color panel in which different colors are arranged in each of the rectangular areas 540 of the plurality of rectangular areas 540 arranged in a matrix (S110).

Next, the acquisition unit 151 acquires color information indicating a color selected by the user among the plurality of colors arranged in the color panel (S120).

Next, the second control unit 153 controls the lighting fixture 200 so that the lighting fixture 200 emits light having a color indicated by the color information (S130).

For example, the setting unit 154 stores appliance information indicating the lighting appliance 200 in the storage unit 140 in association with the color information between step S120 and step S130. Next, the second control unit 153 controls the lighting fixture 200 so that the lighting fixture 200 associated with the color information stored in the storage unit 140 emits light having a color based on the color indicated by the color information at a predetermined timing. As described above, the second control unit 153 may control the lighting fixture 200 so that the lighting fixture 200 emits light whose color is the color indicated by the color information immediately after step S120.

In step S110, for example, the first control unit 152 causes the plurality of colors arranged in the color panel to be arranged in the color sequence in the first direction D1 on the surface of the display unit 120 and to be displayed on the display unit 120 in the hue sequence in the second direction D2 orthogonal to the first direction D1 on the surface of the display unit 120. Here, for example, the higher the saturation is set for a plurality of colors arranged in the color panel, the larger the color difference of the hues adjacent in the second direction D2 is.

In step S110, for example, the first control unit 152 causes the display unit 120 to display one of the representative color panel 500 and the detailed color panel 510, which are color panels having different colors arranged in a switchable manner. Specifically, for example, the first control unit 152 first displays the representative color panel 500, and when the reception unit 130 receives an instruction to switch the display of the color panel, switches the display of the display unit 120 from the representative color panel 500 to the detailed color panel 510. Here, for example, the number of colors arranged in the representative color panel 500 is smaller than the number of colors arranged in the detailed color panel 510.

In addition, for example, in step S110, the first control unit 152 causes the display unit 120 to display identification information composed of at least one of characters and symbols uniquely representing each of a plurality of colors arranged in the color panel together with the color panel. In the present embodiment, the first control unit 152 displays the respective rows of numerals of the plurality of rectangular areas 540 arranged in a matrix on the display unit 120 together with the detailed color panel image 420 as identification information so as to correspond to the detailed color panel 510, and displays the respective columns of letters on the display unit 120 together with the detailed color panel image 420 as identification information. In the present embodiment, the first control unit 152 causes the display unit 120 to display the identification information 570 so as to overlap with each color of the representative color panel 500.

The first control unit 152 may cause the plurality of colors arranged in the color panel representing at least one of the color panel 500 and the detailed color panel 510 to be arranged in the first direction D1 on the surface of the display unit 120 in the saturation order and to be displayed on the display unit 120 in the second direction D2 orthogonal to the first direction D1 on the surface of the display unit 120 in the hue order. For example, the plurality of colors arranged in the at least one color panel may be set such that at least one of a color difference between the hue adjacent to the color panel in the second direction D2 and a color difference between the color panel and the color adjacent to the color panel in the first direction D1 increases as the color density increases. For example, the first control unit 152 causes the plurality of colors arranged in the detailed color panel 510 to be arranged in the first direction D1 in the order of saturation and to be displayed on the display unit 120 in the order of hue in the second direction D2 orthogonal to the first direction D1, and sets the plurality of colors arranged in the detailed color panel 510 such that the higher the saturation, the larger the color difference between the adjacent hues in the second direction D2 and/or the higher the saturation, the larger the saturation difference between the adjacent colors in the first direction D1. For example, the first control unit 152 may extract a predetermined number of colors from the plurality of colors of the detailed color panel 510 obtained by arranging the plurality of colors in this way, and create the representative color panel 500.

[ modification of color Panel ]

The representative color panel 500 and the detailed color panel 510 may be displayed on different screens or may be displayed on the same screen.

Fig. 12 is a diagram showing a color panel image 700 according to the embodiment.

The color panel image 700 is an image including a representative color panel 501 and a detailed color panel 511.

In this way, the shape (outer edge shape) of the representative color panel may be rectangular as in the representative color panel 500 or may be non-rectangular as in the representative color panel 501.

The detailed color panel may or may not have a rectangular shape (outer edge shape).

For example, the first control unit 152 assigns a number to each of the detailed color panel 511 or the representative color panel 501 and the detailed color panel 511, and displays the assigned number on each color panel. Specifically, for example, in the detailed color panel 511 or the representative color panel 501 and the detailed color panel 511, the first control unit 152 assigns numbers to the respective colors of the plurality of colors arranged in the panel for each panel, and causes the assigned numbers to be displayed on the respective color panels. For example, even for panels of different colors, the same color is assigned the same number.

The assigned number may be arbitrarily determined, and is not particularly limited. For example, the assigned number may be determined arbitrarily in advance, or in the case where the user sets a color arranged in the color panel, the first control unit 152 may assign numbers to the respective colors of the plurality of colors to be set, for example, in the order of saturation.

In addition, when the display unit 120 can display a plurality of color panels, such as the representative color panel 501 and the detailed color panel 511, a unique number may be determined for each color panel. The number may be determined arbitrarily in advance or by the first control unit 152.

For example, when the user selects one color among the plurality of colors arranged in the representative color panel 501, the first control unit 152 causes the display unit 120 to display a detailed color panel 511 of the plurality of colors arranged in the periphery of the one color. For example, when the color corresponding to the color number C02 is selected by the user, the first control unit 152 causes the display unit 120 to display the detailed color panel 511 in which the color corresponding to C02 and the color corresponding to the color numbers a01 to E03 as the color around the color corresponding to C02 are arranged.

Further, the number of colors displayed in the detailed color panel 511 is not particularly limited. The number of colors that can be displayed on the detailed color panel 511 may be larger than the number of colors that can be displayed on the representative color panel 501, or the number of colors that can be actually displayed may be smaller than the number of colors that can be actually displayed on the representative color panel 501. For example, when an operation of an arrow positioned around the detailed color panel 511 is received from a user while the color panel image 700 is displayed or an operation of sliding the detailed color panel 511 is received, the first control unit 152 changes the color displayed on the detailed color panel 511 in response to the operation.

[ Effect etc. ]

The invention based on the disclosure of the present specification will be exemplified below, and effects and the like obtained based on the exemplified invention will be described.

In recent years, the number of colors that can be displayed on a display by a computer has become enormous. For example, when a plurality of colors are displayed on a display and a user selects an arbitrary color from among the plurality of colors displayed, when a large number of colors are displayed on the display, the display size of each color may be reduced due to the limitation of the size of the display. Thus, there is a problem in that it is difficult for the user to select a color. In this case, for example, when a large number of colors are displayed on a display, there is a problem that it is difficult for a user to distinguish between the colors. Thus, for example, there are the following problems: although the user wants to repeatedly select the same color, other colors are erroneously selected.

Accordingly, in the present invention, there is provided an illumination system 300 in which a predetermined number of colors are arranged on a color panel and displayed on the display unit 120, whereby the number of colors to be displayed is suppressed from becoming large, and a user can easily select a color.

The invention 1 is an illumination system 300, comprising: a first control unit 152 that causes the display unit 120 to display a color panel in which different colors are arranged in each of a plurality of areas (for example, rectangular areas 540) arranged in a matrix; an acquisition unit 151 that acquires color information indicating a color selected by a user among a plurality of colors arranged in a color panel; and a second control unit 153 that controls the lighting fixture 200 such that the lighting fixture 200 emits light having a color indicated by the color information, wherein the first control unit 152 causes the plurality of colors arranged in the color panel to be arranged in a color sequence in a first direction D1 on the surface of the display unit 120 and in a second direction D2 orthogonal to the first direction D1 on the surface of the display unit 120 and to be displayed on the display unit 120, and wherein the plurality of colors arranged in the color panel are arranged such that at least one of a color difference of adjacent colors in the second direction D2 and a color difference between adjacent colors in the first direction D1 increases as the color is set to be higher in color.

The color panel is, for example, at least one of the representative color panel 500 and the detailed color panel 510.

In addition, for example, the plurality of colors arranged in the color panel are set such that at least one of the color difference of the hues adjacent in the second direction D2 and the chroma difference between the colors adjacent in the first direction D1 is larger as the maximum chroma included in the first direction D1 is higher. More specifically, with respect to the colors arranged in the color panel, the farther the maximum chroma is from the white region (that is, the higher the maximum chroma is), the larger the color difference of the hue is, and the closer the maximum chroma is to the white region (that is, the lower the maximum chroma is), the smaller the color difference of the hue is.

According to the illumination system 300 of the invention 1, the farther the plurality of colors arranged in the color panel are set to be from the white color in the chromaticity diagram, that is, the higher the chroma, the wider the color difference of adjacent hues or the interval of the chroma. The higher the chroma, the smaller the change in color in appearance with respect to the color difference or change in chroma of the adjacent hue. Therefore, a plurality of colors having relatively large changes in appearance are selected and arranged on the color panel. Thus, the color panel can be reduced in the number of colors similar in appearance, and thus it is possible to suppress the arrangement of many unnecessary colors in the color panel. Therefore, according to the illumination system 300 according to the invention 1, the user can simply select the color.

The invention 2 is an illumination system 300, comprising: a first control unit 152 that causes the display unit 120 to display one of the representative color panel 500 and the detailed color panel 510 in a switchable manner, the representative color panel 500 and the detailed color panel 510 being color panels in which different colors are arranged in each of a plurality of areas arranged in a matrix; an acquisition unit 151 that acquires color information indicating a color selected by a user among a plurality of colors arranged in a color panel representing at least one of the color panel 500 and the detailed color panel 510; and a second control unit 153 that controls the lighting fixture 200 such that the lighting fixture 200 emits light having a color that is based on the color indicated by the color information, wherein the number of colors arranged in the representative color panel 500 is smaller than the number of colors arranged in the detailed color panel 510.

The representative color panel 500 and the detailed color panel 510 are examples of color panels, respectively.

According to the illumination system 300 according to the invention 2, the representative color panel 500 in which the number of colors is limited can be displayed. Therefore, according to the illumination system 300 according to the invention 2, the user can easily perform color selection by confirming the representative color panel 500. Further, since the detailed color panel 510 having a large number of colors can be displayed, the user can select a finer color.

In the invention 3, it is provided that: a first control unit 152 for displaying a color panel, which is obtained by disposing different colors in each of a plurality of areas arranged in a matrix, on the display unit 120; an acquisition unit 151 that acquires color information indicating a color selected by a user among a plurality of colors arranged in a color panel; and a second control unit 153 for controlling the lighting fixture 200 so that the lighting fixture 200 emits light having a color indicated by the color information, wherein the first control unit 152 causes the display unit 120 to display, together with the color panel, identification information composed of at least one of characters and symbols uniquely indicating each of a plurality of colors arranged in the color panel.

According to the illumination system 300 of the invention 3, for example, by receiving a user selection of a color by inputting a character or a symbol corresponding to a desired color, the user can easily select a color as compared with a case where a plurality of colors are displayed on a touch panel display or the like and the displayed color is directly tapped by the user to receive the user selection of a color. In addition, for example, when the user repeatedly selects the same color, the user can manage the color using the identification information, and thus, it is possible to suppress that the user cannot recognize the color and erroneously selects another color. Therefore, according to the illumination system 300 of the invention 3, the user can simply select the color.

The invention 4 is the lighting system 300 according to the invention 3, wherein the identification information is a number uniquely indicating each of a plurality of colors arranged in the color panel.

Accordingly, for example, the user inputs a number corresponding to a desired color to accept a user selection of the color, whereby the user can easily select the desired color.

The invention 5 is the illumination system 300 according to the invention 3 or the invention 4, wherein the first control unit 152 causes the display unit 120 to display the identification information 570 so as to correspond to a plurality of rows and a plurality of columns of a plurality of areas arranged in a matrix.

The invention 6 is the lighting system according to any one of the inventions 3 to 5, wherein the first control unit 152 causes the display unit 120 to display a scene name indicating an illumination system of the lighting fixture 200, a color of light emitted from the lighting fixture 200 in the illumination system, and identification information 570 set for the color.

Accordingly, the user can easily confirm the illumination mode set by the illumination appliance 200.

The invention 7 is the lighting system 300 according to the invention 3, wherein the acquisition unit 151 acquires, as the color information, identification information 570 indicating any one of a plurality of colors among identification information 570 uniquely indicating each of the plurality of colors arranged in the color panel, and the first control unit 152 causes the display unit 120 to display information indicating that the color indicated by the color information is selected when the color panel is displayed on the display unit 120.

Accordingly, for example, by inputting a number corresponding to a desired color by the user, the user can accept the selection of the color, and thus the user can easily select the desired color regardless of which color panel of the detailed color panel 510 and the representative color panel 500 is seen.

The invention 8 is the lighting system according to the invention 3, wherein the first control unit 152 causes the identification information 570 indicating the color indicated by the color information to be displayed on the outside of the color panel in the display unit 120.

Accordingly, the user can simply confirm the selected color. For example, some of the colors configured in the detailed color panel 510 are sometimes not configured to represent the color panel 500. According to the invention 8, for example, even when the user selects a color not arranged on the representative color panel 500 from the detailed color panel 510, the user can easily confirm the selected color when the display of the display unit 120 is switched from the detailed color panel 510 to the representative color panel 500.

The invention 9 is the lighting system 300 according to any one of the inventions 3 to 8, wherein the first control unit 152 changes the identification information indicating any one of the plurality of colors arranged in the color panel to the character string acquired by the acquisition unit 151 and displays the character string on the display unit 120.

Accordingly, the user can simply set a plurality of colors arranged in the color panel. That is, usability improves.

The invention 11 is the lighting system 300 according to the invention 2 or 7, wherein the first control unit 152 switches whether to display the detailed color panel 510 based on display information indicating whether to display the detailed color panel 510.

Accordingly, the user who does not need to display the detailed color panel 510 any more, and thus, the user can cut down the unnecessary display from the image displayed on the display unit 120, and for example, the button for switching from the display of the representative color panel 500 to the display of the detailed color panel 510 does not need to be displayed on the display unit 120, and thus, the usability is improved.

The invention 12 is the illumination system 300 according to any one of inventions 2, 7, and 11, wherein when the acquisition unit 151 acquires color information in a state in which the representative color panel 500 is displayed on the display unit 120, the first control unit 152 switches the display of the display unit 120 from the display of the representative color panel 500 to the display of the color information and the display of the detailed color panel 510.

Accordingly, since the switching from the display of the representative color panel 500 to the display of the detailed color panel 510 is automatically performed, it is possible to reduce the display unnecessary for the user from the image displayed on the display unit 120, for example, it is no longer necessary to display a button for switching from the display of the representative color panel 500 to the display of the detailed color panel 510 on the display unit 120 or the like, and thus usability improves.

The invention 13 is the lighting system 300 according to any one of the inventions 1 to 12, wherein the second control unit 153 controls the lighting fixture 200 so that the lighting fixture 200 is lighted with a color indicated by the color information when the acquisition unit 151 acquires the color information.

That is, at the time when the user selects a color, the lighting fixture 200 is lighted to the selected color. Accordingly, the user can select the color while checking the actual state of the lighting fixture 200 when it is turned on.

The invention 14 is the lighting system 300 according to any one of the inventions 1 to 13, wherein the second control unit 153 switches whether to control the lighting fixture 200 so that the lighting fixture 200 is turned on in the color indicated by the color information immediately when the acquisition unit 151 acquires the color information, based on the lighting information indicating whether to turn on the lighting fixture 200 in the color indicated by the color information immediately.

For example, the setting unit 154 stores the color indicated by the color information received from the user in the storage unit 140 in association with the lighting fixture 200. For example, when receiving an instruction from the user, the second control unit 153 controls the lighting fixture 200 so that the lighting fixture 200 emits light of a color associated with the information indicating the lighting fixture 200 based on the information stored in the storage unit 140. Accordingly, even when the current lighting state of the lighting fixture 200 is not to be changed immediately, the user can select the color at an arbitrary timing.

The invention 15 is the lighting system according to any one of the inventions 1 to 14, wherein the first control unit 152 changes the color arranged in the color panel based on specification information indicating the color of light that can be emitted from the lighting fixture 200, (i) so that the color of light that cannot be emitted from the lighting fixture 200 is not arranged in the color panel; (ii) The color panel displayed on the display unit 120 is changed to a color panel in which the color of the light that cannot be emitted by the lighting fixture 200 is not arranged, among a plurality of color panels in which at least a part of the arranged colors are different; or (iii) append the color of light that the luminaire 200 is capable of emitting to a color panel.

The plurality of color panels are, for example, the representative color panel 500 and the detailed color panel 510, but may be other color panels. The information indicating the other color panel may be stored in the storage unit 140 in advance, or may be generated by the first control unit 152 so that at least some of the plurality of colors arranged in the representative color panel 500 or the detailed color panel 510 can be changed.

Accordingly, the color arranged in the color panel is set to the color existing in the specification of the lighting fixture 200. Therefore, for example, the occurrence of a problem that the light of the color selected by the user cannot be emitted from the lighting fixture 200 can be suppressed.

The invention 16 is the lighting system 300 according to any one of the inventions 1 to 15, wherein the first control unit 152 causes the display unit 120 to display any one of a plurality of color panels having at least a part of different colors among the arranged colors, based on an operation history of the lighting system 300 by a user (more specifically, an operation history of the operation terminal 100).

For example, the first control section 152 changes the color arranged in the representative color panel 500 based on the operation history. Specifically, the first control unit 152 changes the color arranged in the representative color panel 500 so that the color selected by the user with a high frequency in the detailed color panel 510 is arranged in the representative color panel 500. Accordingly, the user can easily select a color frequently selected by the user.

The invention 17 is the lighting system 300 according to any one of the inventions 1 to 16, wherein the first control unit 152 causes the display unit 120 to display any one of a plurality of color panels having at least some of the different colors on the basis of the date-time information.

For example, if summer is the case, the first control unit 152 arranges a plurality of colors of the cold color system in the color panel, and if winter is the case, the first control unit 152 arranges a plurality of colors of the warm color system in the color panel. The ease with which these colors are selected by the user varies, for example, depending on the season. Therefore, for example, by changing the color arranged in the color panel so that the colors that are easily selected become larger according to seasons, the user can easily select the color that is highly likely to be selected by the user.

The invention 18 is the lighting system 300 according to any one of the inventions 1 to 17, wherein when the acquisition unit 151 acquires color fade information indicating a color of a start point of a color fade and a color of an end point of a color fade, the second control unit 153 controls the lighting fixture 200 so that a color of the emitted light changes from the color of the start point to the color of the end point based on the color fade information.

Accordingly, for example, when a scene having a variation in color such as a blue sky to an alizarine sky is defined, the user can simply select the color of the start point and the color of the end point, and can control the illumination apparatus 200 so that the color of the emitted light is faded in and out according to the color of the start point and the color of the end point.

The second control unit 153 may control the lighting fixture 200 so that the lighting fixture 200 irradiates light of a color determined by moving a color of the start point and a color of the end point by an amount corresponding to information of the information on a straight line obtained by connecting the color of the start point and the color of the end point in the chromaticity diagram based on the information indicating the fade-in fade-out time. For example, the acquisition unit 151 acquires the information from the user via the reception unit 130. The information may be determined in advance.

The invention 19 is the lighting system 300 according to the invention 18, wherein the color fade information includes information indicating a color of a relay point set between a color of a start point and a color of an end point, and the second control unit 153 controls the lighting fixture 200 so that the color of the emitted light changes from the color of the start point to the color of the end point via the color of the relay point based on the color fade information.

Accordingly, by adding the relay point, for example, when the user wants to control the color of the light emitted from the lighting fixture 200 to be blue to green to yellow without passing through the white point, the user can set a more desired color fade-in and fade-out.

The invention 20 is the illumination system 300 according to the invention 18 or 19, wherein the first control unit 152 causes the display unit 120 to display the color based on the color fade information in a gradation manner such that the color continuously changes from the color of the start point to the color of the end point.

Accordingly, the user can simply confirm a specific color change based on the color fade information.

The invention 21 is the lighting system according to any one of the inventions 1 to 20, wherein the lighting fixture 200 includes a plurality of light sources that can be individually controlled, and the second control unit 153 controls each of the plurality of light sources based on color information indicating a color of each of the plurality of light sources so that each of the plurality of light sources emits light of the color indicated by the color information for each of the plurality of light sources.

Accordingly, the user can simply cause the lighting fixture 200 to emit light of the corresponding color by selecting the color of each of the plurality of light sources.

The invention 22 is the lighting system according to any one of the inventions 1 to 21, wherein the second control unit 153 controls the lighting fixture 200 based on structural information indicating at least any one of a color, a concavity and convexity, and a material of a surface of the structure so that the surface looks the same as a color indicated by the color information when light emitted from the lighting fixture 200 is irradiated to the surface.

The structure is, for example, a wall, floor, ceiling, or the like of a building or the like.

The following situations exist: the color displayed on the display unit 120 and the color of the surface of the structure to which the light from the lighting fixture 200 is irradiated appear different depending on the state of the surface. For example, in the case where light of the same color is irradiated to a black wall and the case where light is irradiated to a white wall, the colors of the respective walls look different. For example, when light is irradiated to the entire wall by a plurality of lighting fixtures 200, the surface state of the structure such as the irregularities and the color is different, and therefore the color appears to be different depending on the position of the light irradiated to the lighting fixtures 200. For example, when the plurality of lighting fixtures 200 are caused to emit light to different positions, even if the plurality of lighting fixtures 200 are caused to emit light of the same color, the color may appear to be different depending on the position of the surface of the structure. Accordingly, for example, the second control unit 153 corrects the color selected by the user based on the configuration information, and thereby can make the color look the same when light is irradiated from the plurality of lighting fixtures 200 to the wall surface.

The invention 23 is the lighting system 300 according to any one of the inventions 1 to 22, wherein the first control unit 152 causes the display unit 120 to display information indicating the color of light currently emitted from the lighting fixture 200 based on state information indicating the current lighting system of the lighting fixture 200.

Accordingly, the user can simply select the color of the light currently emitted from the lighting fixture 200, for example.

The invention 24 is the lighting system 300 according to any one of the inventions 1 to 23, wherein the first control unit 152 causes the display unit 120 to display an operation button 560 for receiving an input from a user.

Accordingly, the user can simply select a color using the operation button 560.

The invention 25 is the illumination system 300 according to any one of the inventions 1 to 24, wherein the first control unit 152 causes the display unit 120 to display a plurality of color panels in which red, blue, and green, which are the colors of light that can be emitted from the illumination device 200, are arranged in a hue order in a first direction D1 on the surface of the display unit 120 and in a second direction D2 orthogonal to the first direction D1 on the surface of the display unit 120.

Accordingly, the first control unit 152 can display a color panel on which the color of light that can be emitted from the lighting fixture 200 is arranged on the display unit 120. For example, only the colors of light that can be emitted from the lighting fixture 200 can be arranged on the color panel by determining a plurality of colors arranged on the color panel only from the area surrounded by the red dot, the blue dot, and the green dot on the chromaticity diagram.

The invention 26 is the illumination system 300 according to any one of the inventions 2 to 9, 11, and 12, wherein the first control unit 152 causes the plurality of colors arranged in the color panel to be arranged in a color sequence in a first direction D1 on the surface of the display unit 120 and to be displayed on the display unit 120 in a hue sequence in a second direction D2 orthogonal to the first direction D1 on the surface of the display unit 120, and wherein the plurality of colors arranged in the color panel are arranged such that at least one of a color difference of a hue adjacent to the second direction D2 and a color difference between colors adjacent to the first direction D1 is larger as the color is higher.

For example, in the chromaticity diagram, the change in the hue direction and the change in the chroma direction can be separately operated, and the closer the color of the white region, that is, the lower the chroma, the denser the color is extracted, and the farther the color is extracted, that is, the higher the chroma, the more sparsely the color is extracted, whereby the hue can be changed in equal steps regardless of the difference in the chroma. Thereby, a plurality of colors arranged in the color panel can be easily selected.

The invention 27 is the lighting system 300 according to any one of the inventions 1 to 26, wherein the first control unit 152 causes the display unit 120 to display a map (map image 440) in which the appliance icon 520 and the explanatory text 530 representing the lighting appliance 200 are superimposed, and causes the display unit 120 to display the color of the appliance icon 520 and the color of the explanatory text 530 in a color indicated by color information.
