DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments 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, arrangements 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, the components not described in the independent claims are described as optional components.

[0013] Also, each figure is a schematic diagram and is not necessarily drawn precisely. Therefore, for example, the scales etc. in each figure do not necessarily match. Also, in each figure, substantially the same configuration is denoted by the same reference numeral, and overlapping explanations are omitted or simplified.

[0014] Also, in this specification, terms indicating the relationship between elements, terms indicating the shape of elements, and numerical ranges are not expressions representing only strict meanings, but are expressions meaning substantially equivalent ranges, for example, including differences of about several percent.

[0015] (Embodiment) <Configuration and Function> First, with reference to FIGS. 1 to 3B, the configuration and functions of the lighting system 100 according to the embodiment will be described.

[0016] FIG. 1 is a schematic perspective view of the lighting system 100 according to the embodiment. FIG. 2 is a block diagram showing the overall configuration including the lighting system 100 according to the embodiment. FIG. 3A is a diagram showing the lighting device 10 in the lighting system 100 according to the embodiment and the illumination light pattern of the spot illumination light emitted from the lighting device 10 to the irradiation target. FIG. 3B is a diagram combining a plurality of light-emitting elements 121 arranged in a two-dimensional array and the illumination image superimposed on the irradiation target image.

[0017] As shown in FIGS. 1 to 3A, the lighting system 100 is a system that controls the lighting mode of the lighting space. The lighting space is a space illuminated by one or more lighting devices 10, and is, for example, an indoor space such as a room in a building. A plurality of lighting devices 10 are fixed to the ceiling or wall of the lighting space.

[0018] The lighting system 100 includes a lighting device 10 and a terminal device 30. In FIG. 1 and the like, the case where the lighting system 100 includes a plurality of lighting devices 10 is illustrated. That is, the lighting system 100 may include one or more lighting devices 10.

[0019] As shown in FIG. 3A, the lighting device 10 is capable of emitting one or more spot illumination lights to the irradiation target. Therefore, one lighting device 10 can project a plurality of illumination light patterns onto the irradiation target simultaneously by emitting a plurality of spot illumination lights.

[0020] Here, the irradiation target may be a wall surface, a floor surface, a ceiling, a shelf, a table, etc. irradiated with the spot illumination light, or goods and items on display installed thereon.

[0021] Further, the lighting device 10 is, for example, a spotlight and is attached to a wiring fixture (e.g., a wiring duct or a hanging ceiling, etc.) provided on the ceiling or the wall. Note that the lighting device 10 is not limited to a spotlight and may be, for example, a downlight or a ceiling light, etc. The lighting device 10 may be an example of a light source.

[0022] As shown in FIGS. 1 to 3A, the lighting device 10 includes a housing 11, a light emitting module 12, a drive unit 13, a heat sink 14, a lens barrel 15, and a lighting control system 2.

[0023] The housing 11 is a container that houses the light emitting module 12, the drive unit 13, the heat sink 14, and the lens barrel 15. The housing 11 has a cylindrical first housing 111 that houses the light emitting module 12 and the drive unit 13, and a rectangular parallelepiped second housing 112 that houses the lighting control system 2. Note that the lighting control system 2 may be housed in the first housing 111. Also, the housing 11 may be composed of a single housing 11.

[0024] The light emitting module 12 emits, for example, white light. The light emitting module 12 is composed of a plurality of light emitting elements 121 arranged in an array. Specifically, the light emitting module 12 has a plurality of light emitting elements 121 arranged in a two-dimensional matrix and a wavelength converter. The plurality of light emitting elements 121 are regularly arranged in a matrix of M rows and N columns. Here, M and N are natural numbers where at least one of them is 2 or more. M may be equal to N, or M may not be equal to N. The arrangement intervals in the row direction and the column direction of the light emitting elements 121 may be the same or different. In the embodiment, the outer shape of the range where the plurality of light emitting elements 121 are arranged is rectangular, but may be other shapes such as circular. The light emitting module 12 may be an example of a light source, and the light emitting element 121 may be an example of a light source.

[0025] Each of the plurality of light-emitting elements 121 is, for example, a blue light-emitting element that emits blue light. Note that a green light-emitting element that emits green light and / or a red light-emitting element that emits red light can also be used. In each of the plurality of light-emitting elements 121, a yellow phosphor as an example of a wavelength converter is disposed on the light-emitting side of the blue light-emitting element. The blue light-emitting element is, for example, an LED (Light Emitting Diode). Specifically, the blue light-emitting element is a fine LED having a size on the order of several hundred μm, for example. The yellow phosphor is a phosphor that is excited by blue light and emits yellow light. Each light-emitting element 121 emits white light as a mixed light of blue light and yellow light. The yellow phosphor is, for example, a YAG (yttrium aluminum garnet) - based phosphor, but is not limited thereto.

[0026] Note that the yellow phosphor may be provided so as to cover the plurality of blue light-emitting elements. For example, with respect to the plurality of blue light-emitting elements arranged in a two-dimensional matrix, a yellow phosphor that entirely covers the plurality of blue light-emitting elements may be disposed.

[0027] The driving unit 13 supplies a current for driving the light-emitting module 12. Specifically, the driving unit 13 supplies a current for driving each of the plurality of light-emitting elements 121 independently of each other (that is, individually) according to the control information received from the control unit 222 of the lighting control system 2 described later. Thereby, lighting, extinguishing, light emission intensity, light emission time, etc. of the plurality of light-emitting elements 121 are individually controlled. For example, by individually controlling the lighting and extinguishing of the plurality of light-emitting elements 121, spot illumination light with light and dark can be emitted for each region. Then, when the spot illumination light is irradiated onto the irradiation object, an illumination light pattern corresponding to the light and dark can be imaged on the irradiation object.

[0028] Here, the illumination light pattern is a light effect pattern projected by the spot illumination light irradiated onto the irradiation object. When the illumination light pattern is projected onto the irradiation object, the illumination light pattern is produced on the irradiation object.

[0029] As described above, in the embodiment, since the driving unit 13 drives each of the plurality of light-emitting elements 121 independently of one another, it is not necessary to provide a liquid crystal device or a DMD (Digital Mirror Device) in the housing 11 like a general projector, and the size reduction of the lighting device 10 can be easily achieved.

[0030] The driving unit 13 is realized by, for example, an ASIC (Application Specific Integrated Circuit). The driving unit 13 supplies a PWM (Pulse Width Modulation) modulated current to each of the plurality of light-emitting elements 121. Then, the driving unit 13 can change the light emission intensity of each of the plurality of light-emitting elements 121 by adjusting the pulse width of the current supplied to each of the plurality of light-emitting elements 121, and realize a dimming function. Note that the dimming method is not limited to the PMW modulation method, and may be other modulation methods such as an amplitude modulation or a phase modulation method.

[0031] Also, in the embodiment, the driving unit 13 is mounted on one substrate (not shown) together with the light-emitting module 12. The substrate is, for example, a rigid substrate, but may be a flexible substrate. The substrate is provided with, for example, pattern wiring for supplying current from the driving unit 13 to each of the plurality of light-emitting elements 121. Note that the substrate on which the driving unit 13 is mounted and the substrate on which the light-emitting module 12 is mounted may be separate.

[0032] The heat sink 14 is made of, for example, metal and is integrally provided on the metal housing 11. On one surface of the heat sink 14, the substrate on which the light-emitting module 12 and the driving unit 13 are mounted is directly or indirectly fixed via an insulating member or the like. Thereby, since the heat sink 14 and the substrate are thermally connected, the heat generated by the light-emitting module 12 and the driving unit 13 is dissipated through the heat sink 14. For fixing the heat sink 14 to the substrate, fixing members such as an adhesive or a screw are used.

[0033] The lens barrel 15 is an optical member including one or more lenses 151. In the embodiment, the lens barrel 15 applies a predetermined optical effect to the light emitted from the light-emitting module 12 and emits it forward so that the spot illumination light serving as the illumination light pattern forms an image on the irradiation object located in the front. Specifically, the light emitted by the light-emitting element 121 becomes spot illumination light by passing through the lens barrel 15.

[0034] In the embodiment, the lens barrel 15 has a barrel main body and one or more lenses 151 fixed to the barrel main body. In FIG. 3A, two lenses 151 are illustrated. Note that the number, shape, outer diameter, etc. of the lenses 151 included in the lens barrel 15 are appropriately determined according to, for example, the functions required for the lens barrel 15. In the embodiment, the lens barrel 15 is movable in the front-rear direction with respect to the light-emitting module 12. Thereby, the position of the lens barrel 15 can be adjusted so that an illumination light pattern based on the spot illumination light forms an image on the irradiation object according to the distance between the illumination device 10 and the irradiation object irradiated with the spot illumination light. That is, in the embodiment, the illumination device 10 can adjust the focus of the illumination light pattern based on the spot illumination light.

[0035] The illumination control system 2 includes a first communication unit 21, a first processing unit 22, a first storage unit 23, and a power supply unit 24. Note that the illumination control system 2 only needs to include at least the first processing unit 22, and may not include the first communication unit 21, the first storage unit 23, and the power supply unit 24.

[0036] The first communication unit 21 performs wired or wireless communication with the terminal device 30. In this embodiment, the first communication unit 21 wirelessly communicates with the terminal device 30 via an access point AP. Specifically, when the first communication unit 21 performs wireless communication with the terminal device 30, the first communication unit 21 may use short-distance wireless communication such as ZigBee (registered trademark) or wireless LAN (Local Area Network). The wireless communication method (communication standard) may be communication via a wide area communication network such as the Internet. The communication between the first communication unit 21 and the terminal device 30 may be wired communication. The wired communication is, for example, communication using power line communication (PLC) or a wired LAN. The first communication unit 21 is realized by, for example, an antenna and a wireless processing circuit that processes a signal received by the antenna.

[0037] The first processing unit 22 is realized by, for example, an LSI (Large Scale Integration) integrated circuit (IC). Note that the integrated circuit is not limited to an LSI, and may be a dedicated Alternatively, the first processing unit 22 may be a programmable circuit or a general-purpose processor. In the embodiment, the first processing unit 22 is a microcontroller. 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, and a processor for executing the program. The first processing unit 22 may be a programmable FPGA (Field Programmable Gate Array) or a circuit in an LSI. The first processing unit 22 may be a reconfigurable processor in which the connections and settings of the path cells are reconfigurable. The functions executed by the first processing unit 22 may be realized by software or hardware.

[0038] The first processing unit 22 includes an acquisition unit 221 and a control unit 222 .

[0039] The acquisition unit 221 acquires, from the terminal device 30 via the first communication unit 21, a control instruction for controlling the lighting device 10 based on an instruction input to the input unit 32. The control instruction is an instruction input by the user to realize a lighting light pattern projected onto an irradiation object. The control instruction includes, for example, an instruction to project a lighting light pattern imitating a figure drawn by hand by the user onto the irradiation object, an instruction to project a lighting light pattern imitating a figure selected by the user onto the irradiation object, and the like.

[0040] In the embodiment, the acquisition unit 221 acquires a control instruction by detecting a user operation using an operating body with the terminal device 30 having an input unit 32 that accepts input by detecting the movement of the operating body. Specifically, when the terminal device 30 detects a user operation, a control instruction based on the operation is transmitted from the terminal device 30 to the first communication unit 21 of the lighting control system 2. Then, the acquisition unit 221 acquires the control instruction received by the first communication unit 21. Here, the operating body is a pointing device such as a user's finger, pen, or mouse.

[0041] The control unit 222 controls a plurality of individually controllable light emitting elements 121 based on the control instruction acquired by the acquisition unit 221, so as to emit light that forms a lighting light pattern from the light emitting module 12.

[0042] Specifically, the grid shown in FIG. 3B represents a plurality of light-emitting elements 121 arranged in a two-dimensional array. Also, the grid generally coincides with the irradiation range displayed on the terminal device 30 that issues control instructions. In other words, the control unit 222 normalizes the illumination image within the irradiation range so that the two-dimensional array in which the plurality of light-emitting elements 121 are arranged generally coincides with the irradiation range displayed on the terminal device 30 that issues control instructions. As a result, each of the plurality of pixels included in the illumination image and the plurality of light-emitting elements 121 in the two-dimensional array correspond one-to-one. For example, the pixel at the upper left corner in the irradiation range corresponds to the light-emitting element 121 at the upper left corner in the two-dimensional array. Here, the illumination image is an image (showing the illumination light pattern) that simulates the illumination light pattern formed when the actual spot illumination light is irradiated onto the actual irradiation object.

[0043] The control unit 222 determines the illumination light pattern based on the control instructions. Specifically, the control unit 222 identifies one or more pixels corresponding to the illumination image within the irradiation range and one or more light-emitting elements 121 respectively corresponding thereto. Also, the control unit 222 determines the luminance of each of the one or more light-emitting elements 121 based on the pixel values of the one or more pixels. Then, the control unit 222 generates control information based on the identified one or more light-emitting elements 121 and the luminance of each of the one or more light-emitting elements 121. Here, the control information includes information regarding the lighting, extinguishing, light emission intensity, and light emission time, etc. of each of the plurality of light-emitting elements 121.

[0044] Then, the control unit 222 outputs the generated control information to the driving unit 13. The driving unit 13 drives the plurality of light-emitting elements 121 individually according to the received control information. That is, the driving unit 13 supplies current to one or more light-emitting elements 121 indicated in the control information among the plurality of light-emitting elements 121 to turn them on, and does not supply current to the remaining light-emitting elements 121 indicated in the control information to turn them off. As a result, light that becomes spot illumination light is irradiated from the light-emitting module 12, and the spot illumination light irradiated from the lighting device 10 is irradiated onto the irradiation object, for example, so that the illumination light pattern can be imaged on the irradiation object.

[0045] The first storage unit 23 is a storage device that stores computer programs and the like executed by the first processing unit 22. The first storage unit 23 is realized by, for example, a semiconductor memory.

[0046] The power supply unit 24 supplies power for operation to the lighting control system 2 and the light emitting module 12. The power supply unit 24 has, for example, an AC-DC converter circuit, converts the AC power supplied from the commercial power supply 4 into DC power, and supplies the converted DC power to each part of the lighting control system 2 and the light emitting module 12.

[0047] Next, the terminal device 30 according to the embodiment will be described.

[0048] The terminal device 30 is a portable terminal such as a smartphone or a tablet terminal, for example. In the embodiment, the terminal device 30 is a tablet terminal. Note that the terminal device 30 may be a device fixed to a wall or the like, or a device such as a desktop or laptop personal computer.

[0049] As shown in FIG. 2, the terminal device 30 includes a display unit 31, an input unit 32, a second processing unit 33, a second storage unit 34, and a second communication unit 35.

[0050] The display unit 31 displays an irradiation target image indicating an irradiation target object, or displays an illumination image indicating an illumination light pattern irradiated on the irradiation target object. Further, the display unit 31 can also display a figure drawn by a user's handwriting when the user traces the display screen of the display unit 31.

[0051] The display unit 31 is realized by, for example, a liquid crystal display panel or an organic EL (Electroluminescence) display panel or the like. In the embodiment, the display unit 31 is realized by a touch panel display including a touch sensor as the input unit 32.

[0052] In the input unit 32, by detecting the operation of the user, the operation of the user is input. Specifically, the input unit 32 detects the movement of the operating body that touches the display screen of the display unit 31. Thereby, the input unit 32 acquires a control instruction based on the input of the user.

[0053] When the user wants to irradiate a desired illumination light pattern on the irradiation object, the user inputs a control instruction to execute the desired illumination light pattern for illuminating the irradiation object to the input unit 32, or the user inputs a control instruction to execute the illumination light pattern set in the input unit 32. The input unit 32 outputs a control instruction based on the setting input of the user to the illumination control unit 133 and the display control unit 134.

[0054] The second processing unit 33 is realized by, for example, an LSI which is an integrated circuit. Note that the integrated circuit is not limited to an LSI, and may be a dedicated circuit or a general-purpose processor. In the embodiment, the second processing unit 33 is a microcontroller. 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, and a processor for executing the program. Further, the second processing unit 33 may be a programmable FPGA, or a reconfigurable processor in which the connection and setting of circuit cells in the LSI can be reconfigured. The functions executed by the second processing unit 33 may be realized by software or by hardware.

[0055] The second processing unit 33 has a display control unit 134 and an illumination control unit 133.

[0056] The display control unit 134 acquires the irradiation target image by the first communication unit 21 receiving the irradiation target image transmitted from an external device. Further, the display control unit 134 can also acquire the irradiation target image from the secondary storage device when the user connects a secondary storage device such as a flash memory to the terminal device 30. The irradiation target image is an image showing the irradiation target object. For example, the irradiation target image may be an image of the irradiation target object itself, or may be a virtual image imitating the irradiation target object. Here, the external device is another mobile terminal, another device fixed to a wall or the like, or a device such as another personal computer.

[0057] The display control unit 134 controls the display unit 31. Specifically, the display control unit 134 acquires from the input unit 32 the control instruction input by the user to the input unit 32. The display control unit 134, in accordance with the control instruction, superimposes the acquired irradiation target image on an illumination image showing an illumination light pattern for illuminating the irradiation target object and then draws it. The display control unit 134 controls the display unit 31 to display the drawn image. That is, the display control unit 134 controls the display unit 31 to superimpose and display on the irradiation target image an illumination image simulating an irradiation range capable of irradiating the irradiation target object with one or more spot illumination lights. Thereby, the display unit 31 displays the irradiation target image and the illumination image. Since the illumination image is displayed on the display unit 31 in a state of being superimposed on the irradiation target image, the user can grasp the position, size, brightness, pattern, and shape of the illumination image based on the irradiation target image and the illumination image.

[0058] Also, by the user inputting a control instruction to the input unit 32, the position, size, brightness, pattern, and shape of the illumination image can be adjusted. Specifically, the display control unit 134 superimposes and draws an illumination image with adjusted position, size, brightness, pattern, and shape on the irradiation target image according to the control instruction by the user's operating body, and controls to display the drawn image on the display unit 31. In this way, by the user using the terminal device 30, the position, size, brightness, pattern, shape, etc. of the illumination image can be adjusted. Also, by using the terminal device 30, the position, size, brightness, pattern, shape, etc. of the illumination image can be adjusted so as to change periodically. That is, the display control unit 134 can display the illumination image on the display unit 31 as a still image and a moving image.

[0059] The illumination control unit 133 outputs a control instruction for controlling the plurality of illumination devices 10. Specifically, when a control instruction capable of controlling the illumination light pattern projected onto the irradiation target by one or more spot illumination lights by selectively controlling each of the plurality of light emitting elements 121 is input to the input unit 32, the illumination control unit 133 outputs the input control instruction. The control instruction is associated with the above-set illumination image. The illumination image simulates the illumination light pattern when the spot illumination light is irradiated from the illumination device 10 onto the irradiation target. Therefore, the illumination device 10 that emits the spot illumination light, the position, size, brightness, pattern, shape, etc. on the irradiation target image are associated with the illumination image. In the present embodiment, the illumination control unit 133 outputs the control instruction to the second communication unit 35, causing the second communication unit 35 to transmit the control instruction to the first communication unit 21 of the illumination device 10. Thereby, the illumination device 10 can form an illumination light pattern by emitting one or more spot illumination lights based on the control instruction onto the irradiation target.

[0060] The second storage unit 34 stores lighting control data for projecting the illumination light pattern onto the object to be irradiated. The lighting control data includes preset data and data set by the user. The second storage unit 34 is a storage device that stores a computer program or the like executed by the second processing unit 33. The second storage unit 34 is realized by, for example, a semiconductor memory. The second storage unit 34 is an example of a storage unit.

[0061] The second communication unit 35 communicates with the lighting device 10 and an external device. In the embodiment, the second communication unit 35 communicates wirelessly with the lighting device 10 and the external device. When the second communication unit 35 performs wireless communication with the lighting device 10 and the external device, it may be, for example, short-range wireless communication such as ZigBee (registered trademark) or wireless LAN (Local Area Network). Also, the wireless communication method (communication standard) may be communication via a wide-area communication network such as the Internet. Further, the communication between the second communication unit 35 and the lighting device 10 and the external device may be wired communication. The wired communication is, for example, power line carrier communication (PLC) or communication using a wired LAN. The second communication unit 35 is realized by, for example, an antenna and a wireless processing circuit that processes a signal received by the antenna.

[0062] In the present embodiment, by using the terminal device 30 having the above-described configuration and functions, it is possible to adjust the irradiation position, size, brightness, pattern, shape, etc. in the illumination light pattern. Also, by using the terminal device 30, it is possible to adjust the irradiation position, size, brightness, pattern, shape, etc. in the illumination light pattern so as to change dynamically or continuously. That is, in the present embodiment, not only still-image effects but also moving-image effects are possible with the illumination light pattern.

FIG. 8B is another diagram showing an illumination light pattern of spot illumination light emitted by the illumination system 100 according to the embodiment to an irradiation target.

[0065] Here, a case where the user sets a desired illumination light pattern using the terminal device 30 will be described.

[0066] As shown in FIGS. 4 to 8B, the display control unit 134 of the terminal device 30 can display a device selection screen and an irradiation range selection screen on the display unit 31.

[0067] As shown in FIG. 4, on the device selection screen, a plurality of device images A1 to A4 arranged so as to overlap the irradiation target image which is the background of the device selection screen, and the irradiation ranges within which the actual lighting devices 10 corresponding to the plurality of device images A1 to A4 can be irradiated with spot illumination light are shown. On the device selection screen, it is possible for the display control unit 134 to move the irradiation range or for the display control unit 134 to change the device images A1 to A4. In FIG. 4, the display control unit 134 causes the display unit 31 to display, on the device selection screen, the plurality of device images A1 to A4 and the dashed irradiation ranges within which the respective device images A1 to A4 can be irradiated. Here, the plurality of device images A1 to A4 are images imitating the lighting device 10. The plurality of device images A1 to A4 are associated so as to correspond one-to-one with the plurality of lighting devices 10. Further, the display control unit 134 can also display a lighting image on the device selection screen. On the device selection screen, an icon indicating the lighting device 10 and the lighting image are collectively displayed. Thereby, the user can visually recognize what kind of light pattern each lighting device 10 for spatial production projects onto the irradiation object.

[0068] Therefore, the user selects a desired irradiation range from among the plurality of irradiation ranges on the device selection screen displayed on the display unit 31.

[0069] As shown in FIGS. 4 and 5, on the device selection screen, the irradiation target image and the lighting image arranged so as to overlap the irradiation target image are shown. For example, the user selects the irradiation range including the device image A3 and the irradiation range including the device image A4. As shown in FIG. 5, the display control unit 134 may cause the display unit 31 to display a device selection screen showing the irradiation range including the circular lighting image corresponding to the device image A3 and the irradiation range including the rectangular lighting image corresponding to the device image A4 selected by the user.

[0070] On the device selection screen shown in FIG. 5, at least one of the illumination image and the irradiation range can be operated. That is, if the user inputs a control instruction to operate the illumination image on the display screen of the display unit 31 to change the illumination light pattern, the display control unit 134 controls the display unit 31 to change the illumination image imitating the illumination light pattern based on the control instruction input to the input unit 32. Also, if the user inputs a control instruction to operate the irradiation range on the display screen of the display unit 31 to change the position of the irradiation range, the display control unit 134 may control the display unit 31 so that the irradiation range moves within the irradiation target image corresponding to the control instruction input to the input unit 32.

[0071] At this time, the illumination control unit 133 transmits the control instruction to the illumination device 10 associated with the illumination image. As a result, the plurality of light emitting elements 121 of the illumination device 10 are selectively controlled according to the control instruction. By this control, since the irradiation direction of the spot illumination light emitted by the illumination device 10 associated with the illumination image is changed, the position of the illumination light pattern of the spot illumination light irradiated on the irradiation object can be changed. When the irradiation direction of the spot illumination light changes, the illumination light pattern may move (transition) continuously from the point before the change to the point after the change, or the illumination light pattern may instantaneously move from the point before the change to the point after the change.

[0072] Subsequently, when the user further selects (taps the input unit 32) the irradiation range displayed on the device selection screen, an irradiation range selection screen is displayed on the display unit 31 as shown in FIG. 6. In FIG. 6, the display control unit 134 displays the irradiation range selection screen and the device selection screen side by side on the display unit 31. Note that when the irradiation range displayed on the device selection screen is selected, the display control unit 134 may display the irradiation range selection screen on the display unit 31 as a separate screen from the device selection screen.

[0073] On the irradiation range selection screen, it is possible to set the size, brightness, pattern, color tone, shape, etc. of the illumination image corresponding to the irradiation range including the selected device image A3 and the irradiation range including the device image A4, set dynamic changes thereof, or set continuous changes thereof. Note that the irradiation range selection screen is not limited to the case of selecting the above two irradiation ranges. For example, on the irradiation range selection screen, the display control unit 134 can display a state in which one or more irradiation ranges are selected. Also, on the irradiation range selection screen, it is not limited to being displayed while maintaining the positional relationship shown on the device selection screen. For example, on the irradiation range selection screen, the display control unit 134 can display display modes such as list display and tile display. FIG. 6 shows the setting of the shape, brightness, pattern, and hue (for example, color temperature) of the illumination image.

[0074] Note that the shape of the illumination image is not limited to the circular shape and polygonal shape shown in FIGS. 5 and 6. For example, the shape of the illumination image may be other known shapes. The hue is not limited to the color temperature. The hue may be any color tone that can be expressed using at least one of red light, green light, and blue light.

[0075] Also, another example of setting the illumination light pattern will be described with reference to FIGS. 7A to 7E.

[0076] As shown in FIG. 7A, on the device selection screen, two irradiation ranges are exemplified. When the user selects (taps the input unit 32) the edit button displayed in one of the irradiation ranges, the display control unit 134 controls the display unit 31 to display the irradiation range selection screen of FIG. 7B. The user can set the position, size, brightness, pattern, color tone, shape, etc. of the illumination image, set dynamic changes thereof, or set continuous changes thereof on this irradiation range selection screen.

[0077] Also, as shown in FIG. 7C, when the user selects (drags the input unit 32) one of the two irradiation ranges displayed on the device selection screen, the selected irradiation range can be freely moved. In FIG. 7C, the selected irradiation range is moved closer to the other irradiation range. In FIG. 7C, the direction in which one irradiation range moves is indicated by an arrow.

[0078] Note that in FIGS. 7A to 7C, two irradiation ranges are described, but this is merely an example, and the same applies to three or more irradiation ranges.

[0079] As shown in FIG. 7D, a device image can be displayed on the device selection screen. Specifically, on the device selection screen, since the device image can be arranged in association with the irradiation range, when using a plurality of lighting devices 10, the device images corresponding to each lighting device 10 can be visually recognized. In FIG. 7D, one device image is shown on the device selection screen, but a plurality of device images can also be shown on the device selection screen. Furthermore, if the background of the device selection screen is an irradiation target image showing the installation location of each lighting device 10, the device images corresponding to each lighting device 10 can be more visually recognized.

[0080] As shown in FIG. 7E, on the device selection screen, the device image can be set. In the setting of the device image, options such as "Irradiation Setting", "Setting Copy", "Setting Write-Out", "Setting Read-In", "Delete Device", and "Cancel" are shown. In "Irradiation Setting", it is possible to transition to the input mode screen for performing operations such as finger operation, touch pen operation, mouse operation, or keyboard operation on the content to be set for various spot illumination lights. In "Setting Copy", the dialog shown in FIG. 7F is displayed, and the lighting device 10 for which the setting is to be copied can be selected. "Setting Write-Out" is a function that can save the data on the editing screen to the local download folder. The data written out in "Setting Write-Out" can be read in "Setting Read-In". "Setting Read-In" is a function that can read the data stored locally and read the irradiation setting content saved for other lighting devices 10 and scenes. In "Delete Device", the setting content of the lighting device 10 corresponding to the selected icon mark can be deleted together with the icon mark. In "Cancel", the current operation status can be canceled, and it is possible to return to the screen display where operations can be performed again.

[0081] As shown in FIG. 7F, on the device selection screen, when "Setting Copy" is selected in FIG. 7E, the lighting device 10 for which the setting is to be copied can be selected. In FIG. 7E, since "Lighting Device_1" and "Lighting Device_2" exist, it is possible to select the lighting device 10 for which the setting is to be copied from either of them.

[0082] When the user sets the size, brightness, pattern, color tone, shape, etc. of the illumination image on the irradiation range selection screen, or sets dynamic changes or continuous changes thereto, the illumination light pattern of the spot illumination light irradiated on the actual irradiation object also changes. For example, as shown in FIGS. 8A and 8B, when the user changes the shape of the illumination image on the right side from circular to rectangular on the irradiation range selection screen, the display control unit 134 causes the display unit 31 to display the illumination image changed to rectangular on the irradiation range selection screen, and the illumination control unit 133 transmits a control instruction indicating that the shape of the illumination image is rectangular to the illumination device 10 associated with the device image via the second communication unit 35, so that the illumination device 10 changes the illumination light pattern of the spot illumination light irradiated on the irradiation object to rectangular. As a result, the illumination light pattern of the irradiation object on the right side changes from circular to rectangular. Further, the illumination light pattern set in this way is stored in the second storage unit 34 by the second processing unit 33 as illumination control data.

[0083] In this way, in the illumination system 100, the change of the illumination image on the irradiation target image displayed on the display unit 31 can be linked with the change of the illumination light pattern formed on the actual irradiation object. That is, the display control unit 134 superimposes the illumination image on the irradiation target image and displays it on the display unit 31, and the illumination control unit 133 selectively controls each of the plurality of light emitting elements 121 according to the control instruction, so that the illumination light pattern can be projected onto the irradiation object in synchronization. As a result, the user can set the illumination light pattern for the irradiation object.

[0084] <Operation Example 2> Next, with reference to FIGS. 9A and 9B, etc., an operation example performed by the illumination system 100 will be described.

[0085] FIG. 9A is a diagram showing a grouping button displayed when setting grouping on the device selection screen. FIG. 9B is a diagram showing the device selection screen when setting grouping. (a) of FIG. 9B shows the state before setting grouping. (b) of FIG. 9B shows the state after setting grouping. In (a) and (b) of FIG. 9B, the plurality of lighting devices 10 include one or more first lighting devices and one or more second lighting devices. In the device selection screen of (b) of FIG. 9B, the first lighting device is indicated by the device image A1, the second lighting device is indicated by the device image A2, and the device images A1 and A2 are grouped.

[0086] Here, a case where a user sets a desired illumination light pattern by grouping a plurality of lighting devices 10 using the terminal device 30 will be described.

[0087] First, as shown in FIGS. 7A and 7C, the user selects (drags) one of the two irradiation ranges and moves the dragged one irradiation range to a predetermined position.

[0088] Next, the user selects a desired irradiation range for grouping from among the plurality of irradiation ranges in the device selection screen displayed on the display unit 31. At this time, as shown in FIG. 9A, the display control unit 134 controls the display unit 31 to display the grouping button on the device selection screen. That is, one irradiation range and the other irradiation range are in a state where they can be grouped. The grouping button is a button that can determine to group two or more target irradiation ranges into one group. Note that although FIG. 9A describes two irradiation ranges, this is merely an example, and the same applies to three or more irradiation ranges.

[0089] Next, as shown in FIG. 9A, when the user selects one irradiation range and the other irradiation range and turns on the grouping button (inputs to the input unit 32), the input unit 32 groups one irradiation range and the other irradiation range.

[0090] For example, as shown in FIGS. 4 and 9B(b), a grouping of an irradiation range including a device image A1 associated with a first illumination device that projects a first illumination light pattern onto an object to be irradiated and an irradiation range including a device image A2 associated with a second illumination device that projects a second illumination light pattern onto the object to be irradiated is determined. That is, when the user selects the irradiation range including the device image A1 and the irradiation range including the device image A2 and inputs the selected content to the input unit 32, the input unit 32 accepts the grouping of a first illumination image indicating the first illumination light pattern and a second illumination image indicating the second illumination light pattern. Thereby, the second processing unit 33 sets the first illumination image and the second illumination image as one group.

[0091] Note that in FIG. 9B(b), a case where the second processing unit 33 sets two first illumination images and the second illumination image as one group is illustrated. Since one illumination device 10 can simultaneously form a plurality of illumination light patterns, it is not limited to the grouping of one first illumination image and one second illumination image.

[0092] When the grouping is determined, as shown in FIG. 4, the display control unit 134 re-sets and displays on the display unit 31 in the device selection screen the grouped device images A1 and A2, the broken-line irradiation range of the device image A1, and the broken-line irradiation range of the device image A2 in an integrated range.

[0093] At this time, the second processing unit 33 stores the grouping information in the second storage unit 34. The grouping information includes (1) the grouped first illumination image and second illumination image, and (2) a set range obtained by integrating the irradiation range in which one or more first illumination devices can illuminate an object with spot illumination light and the irradiation range in which one or more second illumination devices can illuminate an object with spot illumination light.

[0094] When the user selects a group via the input unit 32, as shown in FIGS. 9B (a) and (b), on the device selection screen, the display control unit 134 controls the display unit 31 to superimpose and display a first illumination image showing a first illumination light pattern and a second illumination image showing a second illumination light pattern on the irradiation target image. On this device selection screen, the positions of the first illumination image showing the grouped first illumination light pattern and the second illumination image showing the second illumination light pattern can be set. For example, on the device selection screen, when the user selects (drags) the grouping displayed on the device selection screen, the integrated range including the grouped first illumination image and second illumination image can be moved. Note that on the device selection screen, it may be possible to move within the integrated range of the grouped first illumination image and second illumination image. That is, the display control unit 134 controls the display unit 31 so that the integrated range can be operated while superimposing and displaying the first illumination image and the second illumination image on the irradiation target image in response to a control instruction. At this time, the illumination control unit 133 transmits the control instruction to the first illumination device associated with the first illumination image and the second illumination device associated with the second illumination image. Thereby, the illumination control unit 133 controls the first illumination light pattern projected onto the irradiation target by the spot illumination light emitted by one or more first illumination devices and the second illumination light pattern projected onto the irradiation target by the spot illumination light emitted by one or more second illumination devices. By this control, since the irradiation directions of the spot illumination lights emitted by each of the first illumination device associated with the first illumination image and the second illumination device associated with the second illumination image can be changed, the positions of the first illumination light pattern and the second illumination light pattern of the spot illumination light irradiating the irradiation target can be changed collectively or individually.

[0095] On the irradiation range selection screen, it is possible to set the positions, sizes, brightness, patterns, color tones, shapes, etc. of the first illumination image and the second illumination image corresponding to the grouped device images A1 and A2, set dynamic changes thereof, or set continuous changes thereof.

[0096] When the user sets the position, size, brightness, pattern, color tone, shape, etc. of the first illumination image and the second illumination image on the irradiation range selection screen, or sets their dynamic changes, or sets continuous changes, the first illumination light pattern and the second illumination light pattern of the spot illumination light irradiated on the actual irradiation object also change. For example, although not shown in the figure, when the user changes the shapes of the first illumination image and the second illumination image from circular to rectangular on the irradiation range selection screen, the display control unit 134 causes the display unit 31 to display the first illumination image and the second illumination image changed to rectangular on the irradiation range selection screen, and the illumination control unit 133 transmits, via the second communication unit 35, a control instruction indicating that the shapes of the first illumination image and the second illumination image are rectangular to the first illumination device and the second illumination device associated with the device images A1 and A2, so that the first illumination device and the second illumination device change the first illumination light pattern and the second illumination light pattern of the spot illumination light irradiated on the irradiation object to rectangular. As a result, the first illumination light pattern and the second illumination light pattern of the irradiation object change from circular to rectangular.

[0097] That is, by grouping the first illumination image and the second illumination image by the display control unit 134, the illumination control unit 133 controls the first illumination device and the second illumination device so that the first illumination light pattern and the second illumination light pattern are projected onto the irradiation object in conjunction with each other.

[0098] In the lighting system 100, it is possible to link the changes in the grouped first illumination image and the second illumination image on the irradiation object image displayed on the display unit 31 with the changes in the first illumination light pattern and the second illumination light pattern formed on the actual irradiation object. As a result, the display control unit 134 superimposes the first illumination image and the second illumination image on the irradiation object image and causes the display unit 31 to display them, and the illumination control unit 133 controls the first illumination device and the second illumination device according to the control instruction, so that the projection of the first illumination light pattern and the second illumination light pattern onto the irradiation object can be synchronized. Also, the illumination light pattern set in this way is stored by the second processing unit 33 in the second storage unit 34 as illumination control data.

[0099] Note that although the grouping settings on the device selection screen have been mainly described here, it is not limited to this. By the input unit 32 accepting the grouping of the first illumination image and the second illumination image on the device selection screen, the grouping may be set for the first illumination image and the second illumination image. The grouping of the first illumination image and the second illumination image is the same as described above. Thereby, the user can set the illumination light pattern for the irradiation object.

[0100] <Operation Example 3> Next, with reference to FIGS. 10 and 11, operation examples performed by the control method and the program will be described.

[0101] FIG. 10 is a flowchart showing operation example 3 of the terminal device 30 according to the embodiment. FIG. 11 is another diagram showing the illumination light pattern of the spot illumination light emitted from the illumination device 10 of the illumination system 100 according to the embodiment to the irradiation object. In FIG. 11, spot illumination light is irradiated onto a specific irradiation object among a plurality of irradiation objects.

[0102] Here, the case where the user sets a desired illumination light pattern using the illumination control data will be described.

[0103] As shown in FIGS. 10 and 11, the user selects the illumination control data for lighting with a desired illumination light pattern from the database of the illumination control data stored in the terminal device 30. At this time, the user re-sets the illumination control data so that an illumination light pattern matching the shape of a specific irradiation object arranged at a predetermined position can be produced by inputting a control instruction to the input unit 32. Thereby, a control instruction from the user is input to the input unit 32 (S11).

[0104] Next, the lighting control unit 133 selectively controls each of the plurality of lighting devices 10 by outputting the control instruction input to the input unit 32 to each of the plurality of lighting devices 10 (S12). Specifically, the lighting control unit 133 transmits a control instruction based on the lighting control data to the lighting device 10 via the second communication unit 35. As a result, as shown in FIG. 11, the lighting device 10 can project a lighting light pattern onto a specific irradiation target by being controlled based on the control instruction using spot illumination light.

[0105] Next, in synchronization with the emission of the spot illumination light, the display control unit 134 controls the display unit 31 to superimpose and display a lighting image showing the lighting light pattern projected onto a specific irradiation target according to the lighting control data on the irradiation target image (S13). As a result, the user can recognize the lighting light pattern projected onto a specific irradiation target from step S12, and can also recognize the irradiation target image displayed on the display unit 31 and the lighting image superimposed on the irradiation target image from step S13.

[0106] Then, the control method and the program end the flowchart of FIG. 10.

[0107] <Operational Effects> Hereinafter, the operational effects of the terminal device 30, the lighting system 100, the control method, and the program in the present embodiment will be described.

[0108] As described above, the terminal device 30 of Technology 1 in the present embodiment includes an input unit 32 to which an instruction (control instruction) for controlling a plurality of light sources (lighting device 10, light emitting module 12, light emitting element 121) capable of emitting one or more spot illumination lights to an irradiation target is input, and in accordance with the instruction (control instruction) input to the input unit 32, each of the plurality of light sources (lighting device 10, light emitting module 12, light emitting element 121) is selectively controlled, thereby generating control information for controlling an illumination light pattern projected onto the irradiation target by the one or more spot illumination lights. The terminal device 30 also includes an illumination control unit 133, a display unit 31 for displaying an irradiation target image indicating the irradiation target, and a display control unit 134 for controlling the display unit 31 to superimpose and display an illumination image indicating the illumination light pattern for illuminating the irradiation target in accordance with the instruction (control instruction) on the irradiation target image.

[0109] According to this, by selectively controlling each of the plurality of light sources (lighting device 10, light emitting module 12, light emitting element 121) by the illumination control unit 133 in accordance with the control instruction, an illumination light pattern can be projected onto the irradiation target. Further, when the illumination light pattern is projected onto the irradiation target, the display control unit 134 can cause the display unit 31 to display the irradiation target image and the illumination image. Therefore, the user can recognize the illumination light pattern projected onto the irradiation target by inputting a control instruction to the input unit 32 while recognizing the irradiation target image and the illumination image displayed on the display unit 31.

[0110] Therefore, it becomes easier for the user to operate the terminal device 30 and to set the illumination light pattern. As a result, the user feels as if they are operating the illumination light pattern itself without having to recognize which lighting device 10 is projecting the illumination light pattern onto the irradiation target.

[0111] Also, the terminal device 30 of Technology 2 in the present embodiment is the terminal device 30 described in Technology 1. In this case, the display control unit 134 controls the display unit 31 to superimpose and display on the irradiation target image an irradiation range capable of irradiating the irradiation target with one or more spot illumination lights.

[0112] According to this, since it can be displayed on the display unit 31 in a state where the irradiation range is superimposed on the irradiation target image, the user can grasp the irradiation range in which the lighting device 10 can irradiate spot illumination light. Therefore, within the irradiation range via the screen, a lighting light pattern for illuminating the irradiation target can be set.

[0113] Also, the terminal device 30 of Technology 3 in the present embodiment is the terminal device 30 described in Technology 2. In this case, the display control unit 134 controls the display unit 31 so that at least one of the illumination image and the irradiation range can be operated in response to an instruction (control instruction) input to the input unit 32, whereby the illumination control unit 133 selectively controls each of a plurality of light sources (lighting device 10, light emitting module 12, light emitting element 121) according to the instruction (control instruction).

[0114] According to this, if it is set to change the illumination light pattern by operating the illumination image on the display screen of the terminal device 30, the illumination control unit 133 selectively controls each of a plurality of light sources (lighting device 10, light emitting module 12, light emitting element 121) in response to this operation. Also, if the irradiation range is moved on the display screen of the terminal device 30, the illumination control unit 133 can move the irradiation range on the display screen of the terminal device 30 so as to coincide with the irradiation range in the real space in response to this movement. Therefore, since the user can operate both the illumination image and the irradiation range, it becomes easier to set the illumination light pattern by operating the terminal device 30.

[0115] Also, the terminal device 30 of Technology 4 in the present embodiment is the terminal device 30 described in any one of Technologies 1 to 3. In this case, the display control unit 134 superimposes the illumination image on the irradiation target image and displays it on the display unit 31, and the illumination control unit 133 selectively controls each of a plurality of light sources (lighting device 10, light emitting module 12, light emitting element 121) according to an instruction (control instruction), thereby synchronizing the projection of the illumination light pattern on the irradiation target.

[0116] According to this, when changing the position, size, brightness, pattern, shape, etc. of the illumination image displayed on the display unit 31, the illumination light pattern projected onto the irradiation object can be changed according to the change of the illumination image.

[0117] Moreover, the terminal device 30 of Technology 5 in the present embodiment is the terminal device 30 described in any one of Technologies 1 to 4. In this case, the plurality of light sources (illumination device 10, light emitting module 12, light emitting element 121) include one or more first light sources (first illumination device, light emitting element 121) and one or more second light sources (second illumination device, light emitting element 121). Further, the illumination control unit 133 controls a first illumination light pattern projected onto the irradiation object by the spot illumination light emitted from one or more first light sources (first illumination device, light emitting element 121), and a second illumination light pattern projected onto the irradiation object by the spot illumination light emitted from one or more second light sources (second illumination device, light emitting element 121). Then, the display control unit 134 controls the display unit 31 to superimpose and display a first illumination image indicating the first illumination light pattern and a second illumination image indicating the second illumination light pattern on the irradiation target image.

[0118] According to this, since a plurality of illumination images can be superimposed and displayed on the irradiation target image, by setting a plurality of illumination images on the same screen, a plurality of illumination light patterns projected onto the irradiation object can be set. Therefore, it becomes easier for the user to operate the terminal device 30, and a plurality of illumination light patterns can be set simultaneously.

[0119] Moreover, the user can grasp a plurality of illumination light patterns simultaneously.

[0120] Further, the terminal device 30 of Technology 6 in the present embodiment is the terminal device 30 described in Technology 5. In this case, the display control unit 134 causes the display unit 31 to display, by superimposing, grouping information including (1) the grouped first illumination image and second illumination image, and (2) a set range obtained by integrating the irradiation ranges in which one or more first light sources (first illumination devices, light emitting elements 121) can illuminate an object with spot illumination light and the irradiation ranges in which one or more second light sources (second illumination devices, light emitting elements 121) can illuminate the object with spot illumination light, on the irradiation target image.

[0121] According to this, in the operation terminal, since a plurality of illumination images can be grouped, the grouped plurality of illumination images can be set collectively. Therefore, it becomes easier for the user to operate the terminal device 30.

[0122] Further, the terminal device 30 of Technology 7 in the present embodiment is the terminal device 30 described in Technology 6. In this case, by the display control unit 134 grouping the first illumination image and the second illumination image, the illumination control unit 133 controls the first light source and the second light source so that the first illumination light pattern and the second illumination light pattern are projected onto the object in conjunction with each other.

[0123] According to this, when the grouped plurality of illumination images are set collectively, the illumination light patterns of the spot illumination light emitted from the plurality of illumination devices 10 onto the object can be changed collectively. Therefore, it becomes easier for the user to operate the terminal device 30.

[0124] Further, the terminal device 30 of Technology 8 in the present embodiment is the terminal device 30 described in any one of Technologies 1 to 7. In this case, it includes a storage unit (second storage unit 34) that stores illumination control data for projecting an illumination light pattern onto an object. The illumination control unit 133 selectively controls each of the plurality of light sources based on the illumination control data. Then, the display control unit 134 controls the display unit 31 to display, by superimposing, an illumination image showing the illumination light pattern projected onto the object according to the illumination control data, on the irradiation target image.

[0125] According to this, it is possible to store the lighting control data set by the user. Therefore, the user can execute the lighting light pattern using the set lighting control data, or can set the lighting control data again. Therefore, it is possible to realize a lighting light pattern according to the user's request.

[0126] Also, the terminal device 30 of technology 9 in the present embodiment is the terminal device 30 described in any one of technologies 1 to 8. In this case, it includes an acquisition unit (first communication unit 21, acquisition unit 221) that acquires an irradiation target image.

[0127] According to this, it is possible to acquire an irradiation target image on which a lighting image can be superimposed. Therefore, since the user can set the lighting light pattern while viewing the irradiation target image and the lighting image, it becomes easier for the user to set the lighting light pattern compared to the case of operating the lighting image without the irradiation target image.

[0128] Also, the terminal device 30 of technology 10 in the present embodiment is the terminal device 30 described in any one of technologies 1 to 9. In this case, the plurality of light sources (lighting device 10, light emitting module 12, light emitting element 121) include a plurality of light emitting elements 121 arranged in an array.

[0129] According to this, by individually controlling the plurality of light emitting elements 121, the shape of the lighting light pattern can be easily changed.

[0130] Also, the lighting system 100 of technology 11 in the present embodiment includes the terminal device 30 described in any one of technologies 1 to 10, and a plurality of light sources capable of emitting one or more spot lighting lights to the irradiation target.

[0131] Also in this lighting system 100, the same operational effects as those of the above-described terminal device 30 are exhibited.

[0132] In addition, the control method of Technology 12 in the present embodiment includes: an instruction (control instruction) for controlling a plurality of light sources capable of emitting one or more spot illumination lights to an irradiation object is input to the input unit 32; the illumination control unit 133 controls the illumination light pattern projected onto the irradiation object by one or more spot illumination lights by selectively controlling each of the plurality of light sources according to the instruction (control instruction) input to the input unit 32; the display unit 31 displays an irradiation target image indicating the irradiation object; and the display control unit 134 controls the display unit 31 to superimpose and display an illumination image indicating the illumination light pattern for illuminating the irradiation object according to the instruction (control instruction) on the irradiation target image.

[0133] Also in this control method, the same operational effects as those of the terminal device 30 and the like described above are achieved.

[0135] (Other Modification Examples) As described above, the terminal device, illumination system, control method, and program according to the present disclosure have been described based on the above embodiments. However, the present disclosure is not limited to these embodiments. As long as the gist of the present disclosure is not deviated from, various modifications conceived by those skilled in the art applied to the embodiments may also be included within the scope of the present disclosure.

[0136] For example, in the device selection screen related to the terminal device, illumination system, control method, and program in the above embodiment, data obtained by a sensor such as a camera mounted on or connected to the terminal device 30 for moving the irradiation range may be utilized for automatic operation.

[0137] In addition, in the terminal device, lighting system, control method, and program according to the above embodiment, on the device selection screen and the irradiation range selection screen, it may be possible to set an illumination image that becomes an illumination light pattern within the irradiation range. That is, the display control unit 134 may be able to control the display unit 31 so that the illumination image (illumination light pattern) within the irradiation range can be operated in response to an instruction input to the input unit 32.

[0138] In addition, in the terminal device, lighting system, control method, and program according to the above embodiment, it may be superimposed and displayed on the display unit 31 so that each irradiation range can be identified. That is, the display control unit 134 may cause the display unit 31 to display such that a plurality of irradiation ranges overlap.

[0139] In addition, in the terminal device, lighting system, control method, and program according to the above embodiment, the input unit 32 may accept "name", "IP address", etc. as information that can specify each irradiation range. In this case, the display control unit 134 may control the display unit 31 to superimpose and display "name", "IP address", etc. as information that can specify each irradiation range on the irradiation target image. The information that can specify the irradiation range may control the display unit 31 to superimpose and display it on the irradiation target image so as to indicate (adhere to) the irradiation range. Thereby, for example, when replacing the lighting device 10 or correcting the position and orientation of the lighting device 10, the user can easily identify the actually installed lighting device 10 from the information that can specify the irradiation range displayed on the display unit 31.

[0140] In addition, in the terminal device, lighting system, control method, and program according to the above embodiment, when the user inputs to the terminal device 30, the display content of the display screen is aligned so as to match the range and position of the illumination light pattern irradiated by the lighting device 10 on the irradiation target. However, for example, when the imaging unit of the terminal device 30 images a plurality of illumination light patterns irradiated on the irradiation target, the display control unit 134 may automatically align the display content of the display screen based on the image captured by the imaging unit.

[0141] Further, the lighting device 10 used in the terminal device, lighting system, control method, and program in the above embodiment may be a movable lighting fixture including a drive mechanism for adjusting pan, tilt, and focus.

[0142] Also, the division of the functional blocks in the block diagram is an example, and a plurality of functional blocks may be realized as one functional block, one functional block may be divided into a plurality, or a part of the functions may be transferred to other functional blocks. Further, the functions of a plurality of functional blocks having similar functions may be processed by a single piece of hardware or software in parallel or in time division.

[0143] Also, the order in which each step in the flowchart is executed is for exemplification in order to specifically describe the present disclosure, and may be an order other than the above. Also, a part of the above steps may be executed simultaneously (in parallel) with other steps.

[0144] In addition, forms obtained by applying various modifications that can be conceived by those skilled in the art to the above embodiment, and forms realized by arbitrarily combining the components and functions in the embodiment without departing from the gist of the present disclosure are also included in the present disclosure.
