[0003] [Patent Document 1] JP 2019-36400 A Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, lighting fixtures having a plurality of light-emitting elements arranged in an array have been developed. In such lighting fixtures, in order to illuminate only a specific location within the lighting range of the lighting fixture, only the light-emitting elements corresponding to that location are turned on. The selection of the specific location is performed by a control terminal separate from the lighting fixture, but performing the selection for each of the multiple lighting fixtures is one of the factors that hinders user convenience. The invention disclosed in Patent Document 1 is merely based on the technical idea of ​​how to illuminate one lighting fixture, and cannot be said to have been devised from the perspective of improving usability, such as allowing the user to focus on how to effectively manage the illuminated area. It is desired to reduce the burden on the user to be aware of the installation position of the lighting fixture and the settings for each lighting fixture, and to tailor the control so that the usability is limited to operating only how the illuminated surface is desired.

[0005] Therefore, the present invention aims to provide a lighting system, a control method, and a program that can improve user convenience by providing a service that improves usability by reducing the burden of having to be conscious of the installation position of lighting fixtures and the settings of each fixture, and allowing users to concentrate on how to effectively manage the illuminated area. [Means for solving the problem]

[0007] A control method according to one aspect of the present invention is a control method for a first lighting device and a second lighting device executed by a computer, wherein each of the first lighting device and the second lighting device has a plurality of light-emitting elements arranged in an array, and the control method includes: a display step of displaying an operated area having a shape corresponding to a third area that combines a first area to which the first lighting device emits light and a second area to which the second lighting device emits light; a reception step of receiving a selection operation to select a portion of the operated area; and an illumination step of illuminating at least a portion of the plurality of light-emitting elements of each of the first lighting device and the second lighting device based on the received selection operation, thereby illuminating a portion of the third area corresponding to the portion of the third area.

[0008] Moreover, one aspect of the present invention can be realized as a program for causing a computer to execute the above control method, or as a computer-readable non-transitory recording medium storing the program. Effect of the Invention

[0009] According to the present invention, it is possible to easily reorganize the illumination areas of multiple lighting fixtures into a single illumination area, thereby reducing the burden of having to be aware of the installation positions of the lighting fixtures and the settings of each fixture, and allowing the user to concentrate on how to effectively manage the illumination area. From the perspective of providing a service that improves usability, a lighting system, control method and program can be provided that can improve user convenience.

[0011] In the following, a lighting system, a control method, a program, etc. according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that each of the embodiments described below shows a specific example of the present invention. Therefore, the numerical values, shapes, materials, components, arrangement and connection forms of the components, steps, order of steps, etc. shown in the following embodiments are merely examples and are not intended to limit the present invention. Therefore, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0012] In addition, each figure is a schematic diagram and is not necessarily illustrated precisely. Therefore, for example, the scales in each figure do not necessarily match. In addition, in each figure, substantially the same configurations are given the same reference numerals, and duplicated explanations are omitted or simplified.

[0013] Furthermore, in this specification, terms indicating relationships between elements, terms indicating the shapes of elements such as rectangle or circle, and numerical ranges are not expressions that only express a strict meaning, but are expressions that include a substantially equivalent range, for example, a difference of about a few percent.

[0014] In addition, in this specification, ordinal numbers such as "first" and "second" do not refer to the number or order of components, unless otherwise specified, but are used for the purpose of avoiding confusion between and distinguishing between components of the same type.

[0015] (Embodiment) [Lighting system overview] First, an overview of a lighting system according to the present embodiment will be described with reference to FIG.

[0016] FIG. 1 is a block diagram showing a configuration of a lighting system 1 according to the present embodiment. As shown in FIG. 1, the lighting system 1 is a system that controls the lighting state of a lighting space. The lighting space is a space illuminated by one or more lighting fixtures, and is, for example, an indoor space such as a room in a building. A plurality of lighting fixtures are fixed to a ceiling, a wall, or the like of the lighting space. In the following description, a case in which a first lighting fixture 10 and a second lighting fixture 20 illuminate the lighting space will be illustrated as an example, but three or more lighting fixtures may illuminate the lighting space.

[0017] Lighting system 1 is capable of controlling each of first lighting fixture 10 and second lighting fixture 20 based on an operation input from a user via UI unit 101 of control terminal 100. For example, when a user wishes to illuminate a desired area, the user can set the area via UI unit 101 of control terminal 100 without specifically specifying a lighting fixture to illuminate the area.

[0018] Specifically, lighting system 1 has a control terminal 100, a first lighting fixture 10, and a second lighting fixture 20.

[0019] The control terminal 100 is a control device that performs lighting control of the first lighting fixture 10 and the second lighting fixture 20. Lighting control includes not only turning the lights on and off, but also control related to the lighting, such as dimming, adjusting the color, and changing the lighting area (lighting range). In this embodiment, the control terminal 100 performs lighting control based on operation input from a user. The control terminal 100 is connected to each of the first lighting fixture 10 and the second lighting fixture 20 via a network so that they can communicate with each other. The communication is wireless communication or wired communication.

[0020] The control terminal 100 is, for example, a mobile terminal such as a smartphone or a tablet terminal, etc. Alternatively, the control terminal 100 may be an operation terminal fixed to a wall or the like, or a stationary computer device, etc.

[0021] As shown in FIG. 1, the control terminal 100 includes a UI (user interface) unit 101, an acquisition unit 102, and a control unit 103.

[0022] The UI unit 101 is a part that displays an operation screen that can be operated by the user and accepts operation input from the user. That is, the UI unit 101 is an example of a display unit and an example of an operation reception unit. Specifically, the UI unit 101 is a touch panel display that performs both reception and display of operation input. Alternatively, the UI unit 101 may have a display dedicated to display (another example of a display unit) and input devices such as a keyboard, a mouse, and a microphone (another example of an operation reception unit).

[0023] The acquisition unit 102 receives and acquires position information indicating a partial area in the illumination space. The acquisition unit 102 may acquire a plurality of pieces of position information of a partial area in the illumination space. In this case, the plurality of pieces of position information may be represented in a two-dimensional area or in a three-dimensional area. The acquisition unit 102 may further acquire at least one target value of the brightness in the partial area, and the size, shape, and color of the illumination area that illuminates the partial area.

[0024] The brightness is represented by, for example, illuminance. Alternatively, the brightness may be represented by luminous intensity. The color is represented by, for example, color temperature. Alternatively, the color may be represented by color information such as RGB.

[0025] The acquiring unit 102 acquires, based on a selection operation received by the UI unit 101, position information indicating a position (part of an area) selected by the user.

[0026] The control unit 103 controls the UI unit 101, the acquisition unit 102, and the first and second lighting devices 10 and 20. Specifically, the control unit 103 causes at least some of the plurality of light-emitting elements 12 (described later) of each of the first and second lighting devices 10 and 20 to emit light based on the received selection operation, thereby irradiating light onto a portion corresponding to the partial area. Furthermore, the control unit 103 may cause at least some of the plurality of light-emitting elements 12 to emit light based on a target value acquired by the acquisition unit 102. A specific control method of the control unit 103 will be described later.

[0027] The acquisition unit 102 and the control unit 103 are each realized by, for example, an LSI (Large Scale Integration) which is an integrated circuit (IC). The integrated circuit is not limited to an LSI, and may be a dedicated circuit or a general-purpose processor. For example, the acquisition unit 102 and the control unit 103 may be one or more microcontrollers. The microcontroller includes, for example, a non-volatile memory in which a program is stored, a volatile memory which is a temporary storage area for executing the program, an input / output port, a processor for executing the program, and the like. The acquisition unit 102 and the control unit 103 may also be a programmable Field Programmable Gate Array (FPGA), or a reconfigurable processor that allows connection and setting of circuit cells in the LSI. The functions executed by the acquisition unit 102 and the control unit 103 may be realized by software or hardware.

[0028] The first lighting device 10 and the second lighting device 20 each have a plurality of light-emitting elements arranged in an array. Here, the specific configuration of the first lighting device 10 will be described as an example, but the same applies to the second lighting device 20.

[0029] The first lighting device 10 has a lighting circuit 11 and an array light source 13 including a plurality of light-emitting elements 12 arranged in an array (two-dimensionally).

[0030] The lighting circuit 11 controls the light emission of each of the multiple light-emitting elements 12. The lighting circuit 11 turns on, turns off, dims, and adjusts the color of each of the multiple light-emitting elements 12 based on a control command transmitted from the control unit 103. The lighting circuit 11 is realized, for example, by an ASIC. The lighting circuit 11 supplies a PWM-modulated current to each of the multiple light-emitting elements 12. By adjusting the pulse width of the current supplied to each light-emitting element 12, the light emission intensity of each light-emitting element 12 can be changed to realize a dimming function. The dimming method is not particularly limited, and may be an amplitude modulation method, a phase modulation method, or the like.

[0031] Each of the multiple light-emitting elements 12 is a μLED. A μLED is a minute LED with a maximum width of less than 100 μm. The light-emitting element 12 may be a miniLED, a laser light-emitting element, or an organic EL element. A miniLED is an LED with a maximum width of 100 μm or more and 200 μm or less. The multiple light-emitting elements 12 may be LEDs with a maximum width of more than 200 μm.

[0032] The light-emitting element 12 emits light by a current supplied from the lighting circuit 11. The light-emitting element 12 includes, for example, a blue LED and a yellow phosphor arranged on the light-emitting side of the blue LED. The yellow phosphor is excited by a portion of the blue light emitted by the blue LED to emit yellow light. The light-emitting element 12 emits white light as a mixture of the blue light and the yellow light.

[0033] The light emitting elements 12 are mounted on a substrate. The substrate is a rigid substrate, but may be a flexible substrate. The substrate is provided with pattern wiring for electrically connecting each of the light emitting elements 12 to the lighting circuit 11.

[0034] The plurality of light emitting elements 12 are arranged in a 256×256 array in a planar region of a predetermined size on the substrate. The planar region in which the light emitting elements 12 are arranged is, for example, a rectangular region of 3 mm×3 mm. Note that the number of light emitting elements 12 and the size of the region in which they are arranged are merely examples and are not particularly limited. By arranging the plurality of light emitting elements 12 in a narrow region, it is possible to reduce the size of the projection lens (not shown) or improve the light capture efficiency.

[0035] Furthermore, the array light source 13 has a dimming function and a color adjusting function. For example, each of the plurality of light-emitting elements 12 can change the light emission intensity according to the amount of current supplied from the lighting circuit 11. Furthermore, for example, the plurality of light-emitting elements 12 may include a plurality of types of light-emitting elements that emit white light with different color temperatures. By adjusting the light emission intensities of the plurality of types of light-emitting elements, the array light source 13 can emit white light with a desired color temperature.

[0036] The light emitting elements 12 may include a red LED for emitting red light, a green LED for emitting green light, and a blue LED for emitting blue light, so that the array light source 13 can emit colored light other than white light.

[0037] [Control method] Next, a description will be given of a method for controlling lighting system 1. In this control method, a third area formed by combining a first area to which first lighting device 10 emits light and a second area to which second lighting device 20 emits light is registered in advance in control terminal 100 as an area to be operated.

[0038] Fig. 2 is a schematic diagram showing an example of a first area 10A of a first lighting device 10 and an example of a second area 20A of a second lighting device 20 according to an embodiment. Fig. 3 is a schematic diagram showing a third area 30A in which the first area 10A and the second area 20A in Fig. 2 are integrated together.

[0039] As shown in Fig. 2, the first area 10A and the second area 20A are arranged in different ranges in the lighting space. The first area 10A and the second area 20A may overlap, be adjacent to each other, or be separated from each other. As shown in Fig. 3, the third area 30A controls the first area 10A and the second area 20A. In the control method of the lighting system 1, the first lighting device 10 and the second lighting device 20 are controlled collectively by making the coordinates of the first area 10A and the coordinates of the second area 20A common to each other.

[0040] Fig. 4 is a flowchart of a control method according to an embodiment. As shown in Fig. 4, in step S1, the control unit 103 recognizes lighting fixtures to be integrated. Fig. 5 is an explanatory diagram showing a first operation screen G1 displayed on the UI unit 101 according to the embodiment. In the following description, each component included in each screen is a GUI (Graphical User Interface) object that can be operated by the user. Examples of operations performed by the user on GUI objects include a touch operation, a long press operation, a drag operation, and a pinch-in / pinch-out operation.

[0041] As shown in FIG. 5, in step S1, the control unit 103 recognizes the lighting fixtures to be integrated. Specifically, the control unit 103 controls the UI unit 101 to display the first operation screen G1. In the first operation screen G1, four buttons B1 (light a, light b, light c, light d) indicating four lighting fixtures are displayed. By performing a touch operation or the like on the multiple buttons B1, it is possible to select multiple lighting fixtures to be integrated. The user selects multiple lighting fixtures to be integrated by performing a touch operation or the like on the multiple buttons B1 of the UI unit 101. For example, in FIG. 5, "light a" corresponds to the first lighting fixture 10, and "light b" corresponds to the second lighting fixture 20. Accordingly, the control unit 103 recognizes that the first area 10A of the first lighting fixture 10 and the second area 20A of the second lighting fixture 20 are to be integrated.

[0042] In step S2, the control unit 103 recognizes the layout of the first area 10A and the first area 10A. FIG. 6 is an explanatory diagram showing a second operation screen G2 displayed on the UI unit 101 according to the embodiment. As shown in FIG. 6, in step S2, the control unit 103 controls the UI unit 101 to display the second operation screen G2. In the second operation screen G2, the first layout B25, the second layout B26, and the free layout B27 are displayed. The first layout B25 is a layout in which the first area 10A and the first area 10A are vertically arranged. The second layout B26 is a layout in which the first area 10A and the first area 10A are horizontally arranged. The free layout B27 is a layout in which the layout of the first area 10A and the first area 10A can be arbitrarily input by the user. The user selects one of the first layout B25, the second layout B26, and the free layout B27 by touching the UI unit 101 (the first layout B25 in this embodiment). Accordingly, the control unit 103 recognizes that the first area 10A and the second area 20A are arranged in the first layout B25. Note that in the layout display in the free layout B27, it may be possible to try out enlargement, reduction, sliding movement, rotational movement, transformation, and the like, which will be described in step S3 below.

[0043] In step S3, the control unit 103 executes fine adjustment of the layout of the first area 10A and the second area 20A. FIG. 7A is an explanatory diagram showing a third operation screen G3 displayed on the UI unit 101 according to the embodiment. As shown in FIG. 7A, in step S3, the control unit 103 controls the UI unit 101 to display the third operation screen G3. In the third operation screen G3, a frame line L10 showing the outline of the first area 10A and a frame line L20 showing the outline of the second area 20A are displayed. Each of the frame lines L10 and L20 can be enlarged, reduced, slid, rotated, transformed, etc., by performing a touch operation or the like.

[0044] At this time, the control unit 103 controls the first lighting device 10 and the second lighting device 20 to turn on all the light-emitting elements 12 provided in each of the first lighting device 10 and the second lighting device 20. Alternatively, instead of turning on all the light-emitting elements 12, only the number of light-emitting elements 12 that can emit light beams of a visible thickness corresponding to each frame line L10, L20 is turned on. In other words, the first area 10A and the second area 20A are illuminated so that at least the boundary between them is visible. FIG. 7B is a schematic diagram showing a state in which the first area 10A and the second area 20A according to the embodiment are illuminated as a whole. In FIG. 7B, the outer part that is not illuminated is hatched with dots. The first area 10A and the second area 20A are also projected with a first frame line 10B and a second frame line 20B showing the outline of the first area 10A and the second area 20A, respectively. The three horizontally long recesses on the wall illuminated by the first area 10A and the second area 20A in FIG. 7B are illustrated as examples of bookshelves or product display areas on the wall of a store.

[0045] The user touches or operates each of the frame lines L10, L20 in the third operation screen G3 while visually checking the first area 10A and the second area 20A that are actually illuminated. This causes the shape, size, and positional relationship of each of the frame lines L10, L20 to be finely adjusted to match the shape, size, and positional relationship of the actual first area 10A and the second area 20A. Accordingly, the control unit 103 recognizes the shape, size, and positional relationship of the first area 10A and the second area 20A after fine adjustment.

[0046] In step S4, the control unit 103 corrects the relative distortion between the first area 10A and the second area 20A. Fig. 8A is an explanatory diagram showing a fourth operation screen G4 displayed on the UI unit 101 according to the embodiment. As shown in Fig. 8A, in step S4, the control unit 103 controls the UI unit 101 to display the fourth operation screen G4. In the fourth operation screen G4, a first reduce button B11 and a first enlarge button B12 are arranged within a frame line L10, and a second reduce button B21 and a second enlarge button B22 are arranged within a frame line L20.

[0047] At this time, the control unit 103 controls the first lighting device 10 and the second lighting device 20 to project the first frame line 10B and the second frame line 20B as well as the first square 10C and the second square 20C onto the first area 10A and the second area 20A. Fig. 8B is a schematic diagram showing a state in which the first area 10A and the second area 20A according to the embodiment are illuminated and the first frame line 10B and the second frame line 20B and the first square 10C and the second square 20C are projected.

[0048] For example, when first reduce button B11 is touched or otherwise operated, controller 103 controls first lighting device 10 so that the spacing between first squares 10C becomes narrower while maintaining the size of first area 10A. On the other hand, when first expand button B12 is touched or otherwise operated, controller 103 controls first lighting device 10 so that the spacing between first squares 10C becomes wider while maintaining the size of first area 10A.

[0049] Similarly, when the second reduction button B21 is touched or otherwise operated, the controller 103 controls the second lighting device 20 so that the spacing between the second squares 20C is narrowed while maintaining the size of the second area 20A. On the other hand, when the second expansion button B22 is touched or otherwise operated, the controller 103 controls the second lighting device 20 so that the spacing between the second squares 20C is widened while maintaining the size of the second area 20A. For example, with one touch operation, the spacing between the first squares 10C or the second squares 20C is reduced or expanded by a predetermined amount (for example, about several percent of the reference spacing). In other words, the more times the touch operation is performed, the greater the amount of reduction or expansion.

[0050] The user touches the first reduction button B11, the first enlargement button B12, the second reduction button B21, and the second enlargement button B22 while visually checking the projected first frame line 10B and the second frame line 20B, and the first square 10C and the second square 20C. As a result, the user corrects the interval between the first square 10C and the second square 20C so that they are equal. The reduction or enlargement amount of the first square 10C from before the correction to after the correction is the first correction value. Similarly, the reduction or enlargement amount of the second square 20C from before the correction to after the correction is the second correction value. In other words, the first reduction button B11 and the first enlargement button B12 are an example of a first correction unit to which the first correction value is input, and the second reduction button B21 and the second enlargement button B22 are an example of a second correction unit to which the second correction value is input.

[0051] In step S5, the control unit 103 creates the third area 30A by integrating the first area 10A and the second area 20A. Specifically, the control unit 103 creates the shape, size, and positional relationship of the third area 30A based on the shape, size, and positional relationship of the first area 10A and the second area 20A after fine adjustment. Thereafter, the control unit 103 converts the coordinates of the first area 10A and the coordinates of the second area 20A based on the coordinates of the third area 30A to make them common. Based on the conversion result, the control unit 103 calculates which coordinates in the third area 30A each of the light-emitting elements 12 of the first lighting device 10 and the second lighting device 20 corresponds to, and associates them. When this association is performed, the control unit 103 also reflects the first correction value and the second correction value, thereby correcting the relative distortion between the first area 10A and the second area 20A.

[0052] In step S6, the control unit 103 controls the UI unit 101 to display the operated region 50A having a shape corresponding to the third area 30A (display step). Specifically, the control unit 103 controls the UI unit 101 to display the fourth operation screen G4.

[0053] 9A is an explanatory diagram showing a fifth operation screen G5 displayed on the UI unit 101 according to the embodiment. In the fifth operation screen G5, an operated area 50A and an adjustment area 55A are displayed.

[0054] The outline of the operated area 50A corresponds to the outline of the third area 30A created in step S5. The operated area 50A is defined in a two-dimensional coordinate system. Two-dimensional coordinates in the operated area 50A correspond to positions in the third area 30A. In FIG. 9A, the area in the operated area 50A corresponding to the first area 10A (first lighting device 10) and the area corresponding to the second area 20A (second lighting device 20) are separated by a two-dot chain line. This two-dot chain line may or may not actually be displayed.

[0055] In step S7, the control unit 103 performs lighting corresponding to the operation on the operated area 50A. Specifically, when the user performs a touch operation or the like on a predetermined position on the operated area 50A, the control unit 103 controls the UI unit 101 to display the instruction lighting range H1 at the predetermined position. The shape, size, etc. of the instruction lighting range H1 may be determined, for example, by a touch operation, a long press operation, a drag operation, a pinch-in / pinch-out operation, etc. on the operated area 50A. The shape of the instruction lighting range H1 may be, for example, a circle, a polygon, a free curve, a character, a symbol, etc.

[0056] As the instructed illumination range H1 is displayed, the acquisition unit 102 acquires position information within the instructed illumination range H1. The control unit 103 obtains coordinates of the third area 30A corresponding to the position information within the instructed illumination range H1. The control unit 103 extracts only the light-emitting elements 12 that correspond to the coordinates of the third area 30A from among the light-emitting elements 12 of the first lighting device 10 and the light-emitting elements 12 of the second lighting device 20, and causes them to emit light. As a result, the portion of the third area 30A that corresponds to the instructed illumination range H1 is irradiated with light (control step).

[0057] Fig. 9B is a schematic diagram showing a case where a part of the third area 30A according to the embodiment is illuminated. In the operated area 50A in Fig. 9A, three horizontally long designated illumination ranges H1 are arranged vertically, but in Fig. 9B, three actual illumination ranges H2 are illuminated to correspond to the three designated illumination ranges H1.

[0058] The adjustment area 55A is an area for adjusting the instructed lighting range H1. A brightness adjustment object 551, a first shape adjustment object 552, a size adjustment object 553, and a second shape adjustment object 554 are provided in the adjustment area 55A.

[0059] The brightness adjustment object 551 is a GUI object for adjusting the brightness of the designated illumination range H1 and the actual illumination range H2. The brightness adjustment object 551 is a slider, but is not limited to this. The brightness adjustment object 551 may be a text box, a radio button, a drop-down list, or the like.

[0060] The first shape adjustment object 552 is a GUI object for adjusting the longitudinal direction of the designated illumination range H1 and the actual illumination range H2. The first shape adjustment object 552 is a slider, but is not limited to this. The first shape adjustment object 552 may be a text box, a radio button, a drop-down list, or the like.

[0061] The size adjustment object 553 is a GUI object for adjusting the size of the designated lighting range H1 and the actual lighting range H2. The size adjustment object 553 is a slider, but is not limited to this. The size adjustment object 553 may be a text box, a radio button, a drop-down list, or the like.

[0062] The second shape adjustment object 554 is a GUI object for adjusting the shapes of the designated lighting range H1 and the actual lighting range H2 between a circle and a square. The second shape adjustment object 554 is a slider, but is not limited to this. The second shape adjustment object 554 may be a text box, a radio button, a drop-down list, or the like.

[0063] When the user activates the instructed lighting range H1 by performing a touch operation or the like, the range switches to a state where operations can be performed on the brightness adjustment object 551, the first shape adjustment object 552, the size adjustment object 553, and the second shape adjustment object 554. When the user again performs a touch operation or the like on the instructed lighting range H1 in the active state, the range switches to a state where operations can not be performed on the brightness adjustment object 551, the first shape adjustment object 552, the size adjustment object 553, and the second shape adjustment object 554.

[0064] While viewing the actual illumination range H2, the user can adjust the actual illumination range H2 to any brightness, shape, or position by directly deforming and moving the designated illumination range H1 in the operated area 50A or by touching each object in the adjustment area 55A. In this way, the operation up to setting the designated illumination range H1 is an example of a selection operation for selecting a part of the operated area 50A. This selection operation is accepted by the UI unit 101 (acceptance step). In this embodiment, the acceptance step and the control step are included in step S7.

[0065] When the user touches the designated lighting range H1 to activate it and then touches the trash can icon, the control unit 103 controls the UI unit 101 to erase the designated lighting range H1. In conjunction with this, the control unit 103 controls the first lighting fixture 10 and the second lighting fixture 20 to turn off the light-emitting elements 12 corresponding to the designated lighting range H1. The processes from step S1 to step S5 may be performed only once after the first lighting fixture 10 and the second lighting fixture 20 are installed. The items set in this process are reflected in the subsequent control method.

[0066] [Variations] Next, a modified example of the embodiment will be described. In the following description, the same parts as those in the above embodiment will be denoted by the same reference numerals, and the description thereof will be omitted in some cases.

[0067] (Variation 1) In the first modification, a case will be described in which the operated area 50A is further divided. The division process is executed after step S5.

[0068] In the division process, the control unit 103 first recognizes the number of divisions of the operated area 50A. Specifically, the control unit 103 controls the UI unit 101 to display the sixth operation screen G6. FIG. 10 is an explanatory diagram showing the sixth operation screen G6 displayed on the UI unit 101 according to the first modification. In the sixth operation screen G6, buttons B31 to B35 indicating the number of divisions are displayed. The user selects one of the buttons B31 to B35 by touching the UI unit 101 or the like (button B32 (number of divisions=2) in this embodiment). This causes the control unit 103 to recognize the number of divisions of the operated area 50A. In the following description, one unit divided in the operated area 50A may be referred to as a "canvas". When the button B35 is selected, a text box is separately displayed, and the user inputs the number of divisions into the text box. In this way, the buttons B31 to B35 are an example of a division unit to which a division instruction to divide the operated area 50A into multiple parts is input. The dividing section may also be a text box, a drop-down list, or the like.

[0069] Next, the control unit 103 controls the UI unit 101 to display the sixth operation screen G6. Fig. 11A is an explanatory diagram showing the sixth operation screen G6 displayed on the UI unit 101 according to the first modification.

[0070] As shown in FIG. 11A, the sixth operation screen G6 displays the operated area 50A in advance. The sixth operation screen G6 also displays a line L15 indicating the boundary between the first area 10A and the second area 20A. The sixth operation screen G6 displays a first division frame line L31 so as to overlap the operated area 50A. The first division frame line L31 is a frame line for setting the first canvas 31A. The first division frame line L31 can be used to enlarge, reduce, slide, rotate, transform, and the like within the operated area 50A by performing a touch operation or the like.

[0071] At this time, the control unit 103 controls the first lighting fixture 10 and the second lighting fixture 20 to turn on only the light-emitting elements 12 that correspond to the first dividing frame line L31 among the light-emitting elements 12 of the first lighting fixture 10 and the second lighting fixture 20. This is illuminated in the lighting space as the first canvas 31A.

[0072] Fig. 11B is a schematic diagram showing an illumination state for the third area 30A according to Modification 1. As shown in Fig. 11B, a portion of the third area 30A that corresponds to the first canvas 31A is illuminated. In addition, the outline of the third area 30A and the canvas 31A, a line L15, may be projected.

[0073] While viewing the illuminated canvas 31A, the user adjusts the canvas 31A to any size, shape, and position by touching the first dividing frame line L31 in the sixth operation screen G6. In Fig. 11B, the canvas 31A is adjusted to fit on the wall surface.

[0074] Next, the control unit 103 controls the UI unit 101 to display the seventh operation screen G7. Fig. 12A is an explanatory diagram showing the seventh operation screen G7 displayed on the UI unit 101 according to the first modification.

[0075] 12A, the seventh operation screen G7 displays the operated area 50A and the first division frame line L31 in advance. The seventh operation screen G7 also displays a line L15 indicating the boundary between the first area 10A and the second area 20A. The word "SET" is displayed within the first division frame line L31 of the seventh operation screen G7, and the second division frame line L32 is displayed outside the first division frame line L31 so as to overlap the operated area 50A.

[0076] The second division frame line L32 is a frame line for setting the second canvas. The second division frame line L32 is set so that it cannot enter the first division frame line L31. The second division frame line L32 can be enlarged, reduced, slid, rotated, transformed, etc., outside the first division frame line L31 in the operated area 50A by performing a touch operation or the like.

[0077] At this time, the control unit 103 controls the first lighting fixture 10 and the second lighting fixture 20 to turn on only the light-emitting elements 12 that correspond to the second dividing frame line L32 among the light-emitting elements 12 of the first lighting fixture 10 and the second lighting fixture 20. This is illuminated in the lighting space as the second canvas 32A.

[0078] Fig. 12B is a schematic diagram showing an illumination state for the third area 30A according to Modification 1. As shown in Fig. 12B, a portion of the third area 30A that corresponds to the second canvas 32A is illuminated. In addition, the outlines and lines L15 of the third area 30A and the canvases 31A and 32A may be projected.

[0079] While visually checking the illuminated canvas 32A, the user adjusts the canvas 32A to any size, shape, and position by touching the second dividing frame line L32 in the seventh operation screen G7. In Fig. 11B, the canvas 32A is adjusted to fit on the tabletop surface.

[0080] Next, the control unit 103 controls the UI unit 101 to display a first operated area 51A having a shape corresponding to the canvas 31A and a second operated area (not shown) having a shape corresponding to the canvas 32A. Specifically, the control unit 103 controls the UI unit 101 to display an eighth operation screen G8.

[0081] Fig. 13A is an explanatory diagram showing an eighth operation screen G8 displayed on the UI unit 101 according to the embodiment. In the eighth operation screen G8, a first operated area 51A and an adjustment area 55A are displayed. The first operated area 51A and the second operated area can be switched by tabs. In Fig. 13A, the first operated area 51A corresponds to a wall tab, and the second operated area corresponds to a table tab.

[0082] The outline of the first operated area 51A corresponds to the outline of the canvas 31A. The first operated area 51A is defined in a two-dimensional coordinate system. The two-dimensional coordinates in the first operated area 51A correspond to positions on the canvas 31A.

[0083] Although not shown, when the tab is switched, the outer shape of the second operated area corresponds to the outer shape of the canvas 32A. The second operated area is defined in a two-dimensional coordinate system. The two-dimensional coordinates in the second operated area correspond to positions on the canvas 32A. Thus, the first operated area 51A and the second operated area are examples of areas divided based on a division instruction.

[0084] Next, the control unit 103 performs illumination corresponding to the operation on the first operated area 51A and the second operated area. For example, when the user performs a touch operation or the like on a predetermined position of the first operated area 51A, the control unit 103 controls the UI unit 101 to display the designated illumination range H1 at the predetermined position. In response to this, the acquisition unit 102 acquires position information within the designated illumination range H1. The control unit 103 obtains coordinates of the canvas 31A corresponding to the position information within the designated illumination range H1. The control unit 103 extracts only the light-emitting elements 12 corresponding to the coordinates of the canvas 31A from among the light-emitting elements 12 of the first lighting device 10 and the light-emitting elements 12 of the second lighting device 20, and causes them to emit light. As a result, light is irradiated onto the part of the canvas 31A corresponding to the designated illumination range H1. Here, a case where a touch operation or the like is not performed only on the first operated area 51A is illustrated, but the same applies to the second operated area.

[0085] Fig. 13B is a schematic diagram showing a case where a part of the third area 30A according to Modification Example 1 is illuminated. In the first operated area 51A in Fig. 13A, three horizontally long designated illumination ranges H1 are arranged vertically, but in Fig. 13B, three actual illumination ranges H2 are illuminated to correspond to the three designated illumination ranges H1.

[0086] In this way, since a selection operation is accepted for each of the first operated area 51A and the second operated area, the actual illumination range H2 of each of the canvases 31A and 32A can be easily set.

[0087] (Variation 2) In the above embodiment, when correcting the relative distortion between the first area 10A and the second area 20A, the first squares 10C and the second squares 20C are projected together with the first frame line 10B and the second frame line 20B onto the first area 10A and the second area 20A. However, any projection form may be used as long as the relative distortion between the first area 10A and the second area 20A can be corrected. FIGS. 14A to 14C are explanatory diagrams showing other projection forms according to the second modification. FIG. 14A shows a projection form in which some lines of the squares are displayed as auxiliary lines thinner than the other lines. FIG. 14B shows a projection form in which scales are added to the frame lines. FIG. 14C shows a projection form in which dots are added to the main parts. The dashed lines in FIG. 14C may or may not be projected.

[0088] [summary] As described above, the lighting system 1 according to the first aspect of the present invention includes the first lighting fixture 10 and the second lighting fixture 20 each having a plurality of light-emitting elements 12 arranged in an array, and the control terminal 100. The control terminal 100 includes a display unit (UI unit 101) that displays an operated area 50A having a shape corresponding to a third area 30A obtained by integrating a first area 10A to which the first lighting fixture 10 irradiates light and a second area 20A to which the second lighting fixture 20 irradiates light, an operation receiving unit (UI unit 101) that receives a selection operation for selecting a part of the operated area 50A, and a control unit 103 that causes at least a part of the plurality of light-emitting elements 12 of each of the first lighting fixture 10 and the second lighting fixture 20 to emit light based on the received selection operation, thereby irradiating light onto a part of the third area 30A corresponding to the part of the third area 30A.

[0089] According to this, when the user operates operated area 50A having a shape corresponding to third area 30A which is a combination of first area 10A and second area 20A, control unit 103 can collectively control first lighting device 10 and second lighting device 20. In other words, the user can cause any part of third area 30A to be illuminated by first lighting device 10 and second lighting device 20 with a simple operation. This improves user convenience.

[0090] A lighting system according to a second aspect of the present invention is the lighting system according to the first aspect, and the operation receiving unit (UI unit 101) includes a first correction unit (first reduction button B11 and first enlargement button B12) to which a first correction value for the first area 10A is input, and a second correction unit (second reduction button B21 and second enlargement button B22) to which a second correction value for the second area 20A is input. The control unit 103 corrects the relative distortion of the first area 10A and the second area 20A based on the first correction value and the second correction value.

[0091] According to this, the user inputs the first correction value and the second correction value from the first correction unit and the second correction unit, so that the relative distortion of the first area 10A and the second area 20A is corrected. Therefore, the operation on the operated region 50A can be more accurately reflected in the third area 30A.

[0092] A lighting system according to a third aspect of the present invention is a lighting system according to the first or second aspect, and the operation receiving unit (UI unit 101) has a division unit (buttons B31 to B35) into which a division instruction to divide the operated area 50A into multiple areas is input, and a selection operation is received for each area (first operated area 51A, second operated area) divided based on the division instruction.

[0093] According to this, a selection operation is accepted for each divided area based on a division instruction, so that it is possible to further improve user convenience.

[0094] A control method according to a fourth aspect of the present invention is a control method for the first lighting device 10 and the second lighting device 20 executed by a computer. Each of the first lighting device 10 and the second lighting device 20 has a plurality of light-emitting elements 12 arranged in an array. The control method includes a display step of displaying an operated area 50A having a shape corresponding to a third area 30A obtained by integrating a first area 10A to which the first lighting device 10 emits light and a second area 20A to which the second lighting device 20 emits light, a receiving step of receiving a selection operation for selecting a part of the operated area 50A, and an illumination step of illuminating a part of the third area 30A corresponding to the part of the third area 30A by causing at least a part of the plurality of light-emitting elements 12 of each of the first lighting device 10 and the second lighting device 20 to emit light based on the received selection operation.

[0095] According to this, when the user operates operated area 50A having a shape corresponding to third area 30A which is a combination of first area 10A and second area 20A, control unit 103 can collectively control first lighting device 10 and second lighting device 20. In other words, the user can cause any part of third area 30A to be illuminated by first lighting device 10 and second lighting device 20 with a simple operation. This improves user convenience.

[0096] A program according to a fifth aspect of the present invention is a program for causing a computer to execute the control method according to the fourth aspect.

[0097] This can improve user convenience in the same way as the above control method.

[0098] (others) Although the lighting system, control method, and the like according to the present invention have been described based on the above-mentioned embodiment, the present invention is not limited to the above-mentioned embodiment.

[0099] For example, in the above embodiment, the first reduction button B11 and the first enlargement button B12 are exemplified as the first correction unit to which the first correction value is input, and the second reduction button B21 and the second enlargement button B22 are exemplified as the second correction unit to which the second correction value is input. However, the first correction value and the second correction value may be automatically acquired. Specifically, the first frame line 10B and the second frame line 20B and the first square 10C and the second square 20C shown in FIG. 8 are photographed by a camera provided in the control terminal. Based on the photographed image, the control unit 103 calculates and acquires the first correction value and the second correction value that make the interval of the first square 10C equal to the interval of the second square 20C. In this case, the camera and the control unit 103 are the first correction unit and the second correction unit. In this way, the first correction unit and the second correction unit may be configured separately from the UI unit 103, which is the operation reception unit.

[0100] The wireless communication between the control terminal 100 and the first and second lighting fixtures 10 and 20 may be short-range wireless communication such as ZigBee (registered trademark) or wireless LAN (Local Area Network). Alternatively, the wireless communication method (communication standard) may be communication via a wide area communication network such as the Internet. Wired communication may be performed between the control terminal 100 and the first and second lighting fixtures 10 and 20 instead of or in addition to wireless communication. Specifically, the wired communication is communication using power line communication (PLC) or a wired LAN.

[0101] In the above embodiment, the process executed by a specific processing unit may be executed by another processing unit. The order of multiple processes may be changed, or multiple processes may be executed in parallel. The allocation of the components included in the lighting system 1 to multiple devices is just an example. For example, the components included in one device may be included in another device.

[0102] For example, the processes described in the above embodiments may be realized by centralized processing using a single device (system), or may be realized by distributed processing using multiple devices. Also, the processor that executes the above programs may be single or multiple. That is, centralized processing or distributed processing may be performed.

[0103] In the above embodiment, all or part of the components such as the control unit may be configured with dedicated hardware, or may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU (Central Processing Unit) or a processor reading and executing a software program recorded on a recording medium such as a HDD (Hard Disk Drive) or a semiconductor memory.

[0104] Furthermore, the components such as the control unit may be configured with one or more electronic circuits. Each of the one or more electronic circuits may be a general-purpose circuit or a dedicated circuit.

[0105] The one or more electronic circuits may include, for example, a semiconductor device, an IC, or an LSI. The IC or LSI may be integrated into one chip or into multiple chips. Here, we refer to it as an IC or an LSI, but depending on the degree of integration, it may be called a system LSI, a VLSI (Very Large Scale Integration), or an ULSI (Ultra Large Scale Integration). Also, an FPGA that is programmed after the LSI is manufactured can be used for the same purpose.

[0106] Furthermore, the general or specific aspects of the present invention may be realized as a system, an apparatus, a method, an integrated circuit, or a computer program. Alternatively, the present invention may be realized as a computer-readable non-transitory recording medium such as an optical disk, a HDD, or a semiconductor memory on which the computer program is stored. Furthermore, the present invention may be realized as any combination of a system, an apparatus, a method, an integrated circuit, a computer program, and a recording medium.

[0107] In addition, the present invention also includes forms obtained by applying various modifications to each embodiment that a person skilled in the art may think of, and forms realized by arbitrarily combining the components and functions of each embodiment within the scope that does not deviate from the spirit of the present invention.
