Description

[Technical Field]

[0001] The present invention relates to a technique for inputting lighting setting information. [Background technology]

[0002] Lighting has been used in a variety of places for a long time. While it is rare for the light intensity and color tone of lighting used in ordinary homes to be precisely adjusted, the illuminance and color tone of lighting used in art galleries and museums are often precisely adjusted. However, adjusting the illuminance and color tone of lighting is not an easy task, placing a significant burden on the person setting it up. One example of a technology for reducing this burden is disclosed in Patent Document 1. The technology disclosed in Patent Document 1 aims to provide a lighting control device that allows the user to easily change the dimming level and color adjustment level, and provides multiple operating modes, namely a dimming mode and a color adjustment mode, making it possible to perform dimming and color adjustment with a single lighting control device.

[0004] However, in art galleries and museums, for example, a large number of lights are installed due to their size. Therefore, even if the technology disclosed in Patent Document 1 is used, individually setting the light intensity and color tone for each light is a huge burden. Furthermore, in art galleries and museums, exhibits change for each exhibition held several times a year. Each time, it is necessary to reset the setting information for each light, such as the light intensity and color tone, to the optimum setting, which places a heavy burden on the workers. This problem is not limited to art galleries and museums, but is a common problem in facilities that use multiple lights. In view of the above circumstances, the present invention aims to provide a technology that can reduce the effort required to set up lighting in facilities that use multiple lights. [Means for solving the problem]

[0007] One aspect of the present invention is a setting support method in which a computer receives an instruction to change the light intensity information for a combination of multiple lighting devices, and sets the changed light intensity information for each lighting device in accordance with the instruction while maintaining the relative relationships between the light intensity information defined for the multiple lighting devices.

[0008] One aspect of the present invention is a setting support method comprising the steps of: a step in which a computer reads out template information from a template information storage unit that stores template information that indicates the relative relationships of light intensity information of each lighting fixture for a combination of multiple lighting fixtures; and a control step in which the computer sets the light intensity information of each lighting fixture for the combination of multiple lighting fixtures to which the template is assigned, while maintaining the relative relationships indicated by the template information.

[Figure 6] FIG. 10 is a diagram showing a specific example of a template generation screen. DETAILED DESCRIPTION OF THE INVENTION

[0012] Specific configuration examples of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram showing the system configuration of a dimming control system 100 of the present invention. The dimming control system 100 includes multiple lighting fixtures 10, a dimming control device 20, and a setting information input device 30. The dimming control system 100 is a system for setting and controlling the light intensity and color tone of multiple lighting fixtures 10. In the following description, illuminance values ​​are used as one piece of information indicating the light intensity of the lighting fixtures 10. However, other values ​​may be used as the information indicating the light intensity. For example, the information indicating the light intensity may be information indicating a percentage of maximum lighting output or information indicating dimming value steps. The multiple lighting fixtures 10, the dimming control device 20, and the setting information input device 30 are communicatively connected via a network 90. ​​The network 90 may be a network using wireless communication or a network using wired communication. The network 90 may be a combination of multiple networks. The network through which the lighting fixtures 10 and the dimming control device 20 communicate may be configured using different networks from the network through which the dimming control device 20 and the setting information input device 30 communicate.

[0013] Lighting fixture 10 is a lighting device that can change the illuminance and color tone between multiple levels. The power to lighting fixture 10 is turned on and off in response to a control signal transmitted from dimming control device 20. Lighting fixture 10 changes its illuminance and color tone in response to the control signal transmitted from dimming control device 20. Each lighting fixture 10 may be fixedly installed in a predetermined position.

[0014] Dimming control device 20 controls the operation of each lighting fixture 10 included in dimming control system 100. For example, dimming control device 20 controls the illuminance and color tone of each lighting fixture 10. Dimming control device 20 may control each lighting fixture 10 using, for example, a proprietary communication protocol, or may control each lighting fixture 10 using a specific existing communication protocol. Specific examples of existing communication protocols include DALI (registered trademark), DMX512, and DALI2.

[0015] The dimming control device 20 is configured using information equipment such as a personal computer or dedicated equipment. Fig. 2 is a diagram showing a specific example of the functional configuration of the dimming control device 20. The dimming control device 20 includes a communication unit 21, a storage unit 22, and a control unit 23. Each functional unit of the dimming control device 20 will be described below.

[0016] The communication unit 21 is a communication device that communicates with other devices. The communication unit 21 communicates with other devices (for example, lighting fixtures 10 and setting information input devices 30) via a network 90, for example.

[0017] The storage unit 22 is configured using a storage device such as a magnetic hard disk drive, a semiconductor storage device, etc. The storage unit 22 functions as, for example, a map information storage unit 221, a template information storage unit 222, a group information storage unit 223, and a setting information storage unit 224.

[0018] The map information storage unit 221 stores information (hereinafter referred to as "map information") related to a map of a facility in which lighting fixtures 10 are installed (hereinafter referred to as "target facility"). The map information stores, for example, a map of the area in the target facility where at least lighting fixtures 10 are installed, information indicating the locations of each lighting fixture 10, and destination information (e.g., device identification information, address information, etc.) used when transmitting control information to each lighting fixture 10. By referencing the map information stored in the map information storage unit 221, the computer can display on the map the locations of each lighting fixture 10 in the target facility. Furthermore, by referencing the map information stored in the map information storage unit 221, the computer can obtain destination information for transmitting control signals to each lighting fixture 10 specified on the map by the user.

[0019] The template information storage unit 222 stores template information. The template information includes illuminance information for each lighting fixture 10 for each predetermined unit (hereinafter referred to as a "lighting set") that includes multiple lighting fixtures. The illuminance information for each lighting fixture defined in the template information may be, for example, the relative illuminance value of each lighting fixture 10 (hereinafter referred to as "relative illuminance") or the absolute illuminance value of each lighting fixture 10. The template information may also include information related to color tone (e.g., color temperature).

[0020] FIG. 3 is a diagram showing a specific example of a lighting set. One lighting set includes multiple lighting fixtures 10, and the installation position of each lighting fixture 10 is determined. For example, the lighting set in FIG. 3 includes four lighting fixtures 10 (10_1 to 10_4) that are provided to illuminate an exhibition space 50. In the lighting set, the relative value (ratio) of illuminance between each lighting fixture 10 at each position and the other lighting fixtures included in the same lighting set is determined as relative illuminance. For example, the relative illuminance for the lighting set shown in FIG. 3 may be determined as follows: Lighting fixture 10_1:5 Lighting fixture 10_2:20 Lighting fixture 10_3:10 Lighting fixture 10_4:2

[0021] When the relative illuminance of a lighting set is determined in this way, the ratio of the illuminance of the four lighting fixtures 10 is changed while maintaining the above-mentioned relative illuminance relationship. For example, when an operation to increase the illuminance of this lighting set is performed, the setting is updated so that the illuminance value of each lighting fixture 10 is increased while maintaining the above-mentioned relative illuminance relationship. For example, if the four lighting fixtures 10 used in the lighting set of Figure 3 have the same maximum illuminance value, Lighting fixture 10_1: 10% of maximum illumination Lighting fixture 10_2: 40% of maximum illumination Lighting fixture 10_3: 20% of maximum illumination Lighting fixture 10_4: 4% of maximum illumination

[0022] The illuminance of each lighting fixture may be set as follows. After this, if an operation to lower the illuminance of this lighting set is performed, Lighting fixture 10_1: 5% of maximum illumination Lighting fixture 10_2: 20% of maximum illumination Lighting fixture 10_3: 10% of maximum illumination Lighting fixture 10_4: 2% of maximum illumination

[0023] The illuminance of each lighting device may be set as shown below. Note that although the illuminance of each lighting device 10 is shown here as a percentage of the maximum illuminance, it may be expressed in other ways. For example, it may be expressed as a number of steps separated by a predetermined width from the minimum illuminance to the maximum illuminance, or it may be expressed as an absolute value of illuminance.

[0024] The lighting set shown in FIG. 3 is merely one specific example, and other lighting sets may be defined. Furthermore, multiple types of lighting sets may be defined in one target facility. The template information may further include label information in addition to the relative illuminance for each lighting set. Label information is information indicating the situation in which the template is used. For example, information indicating the type of exhibit for which the template is used may be provided as label information. Specific examples of the type of exhibit may include values ​​such as hanging scroll, folding screen, and kimono. Information indicating the center of gravity of the light may also be defined as label information. For example, label information such as the entire wall surface or the center of the eyeline (gaze line) may be defined.

[0025] The group information storage unit 223 stores group information. Group information is information about a group that includes one or more lighting devices 10. The group information may be defined, for example, in units of one or more lighting sets. The group information includes information about the lighting devices 10 included in the group. The group information may be defined, for example, by the user or may be predetermined. The group information may be deleted or updated, for example, by the user.

[0026] The setting information storage unit 224 stores setting information, which includes setting values ​​such as illuminance and color tone for each lighting device 10.

[0027] The control unit 23 is configured using a processor such as a CPU (Central Processing Unit) and a memory. The control unit 23 functions as a recording control unit 231, a setting support unit 232, and a lighting control unit 233 by the processor executing a program. Note that all or part of the functions of the control unit 23 may be realized using hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The above program may be recorded on a computer-readable recording medium. Examples of computer-readable recording media include portable media such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, and a semiconductor storage device (e.g., an SSD: Solid State Drive), as well as storage devices such as a hard disk or semiconductor storage device built into a computer system. The above program may be transmitted via a telecommunications line.

[0028] The recording control unit 231 acquires predefined map information and template information from another device (for example, the setting information input device 30 or another device) and records it in the storage unit 22. For example, when the dimming control system 100 is introduced into the target facility, the recording control unit 231 may receive map information to be registered at initial setting from another device and record it in the map information storage unit 221.

[0029] The setting support unit 232 supports the user in setting the illuminance and color tone of each lighting fixture 10. For example, the setting support unit 232 provides information required for setting to the setting information input device 30 used by the user. For example, the setting support unit 232 may provide template information or group information to the setting information input device 30. For example, the setting support unit 232 receives information set based on the template information or group information (information on settings assigned to each lighting set or each group) from the setting information input device 30, calculates setting values ​​for each lighting fixture 10 included in each lighting set or each group based on the received information, and records the calculated values ​​in the setting information storage unit 224. Note that the setting values ​​for each lighting fixture 10 included in each lighting set or each group may be calculated in the setting information input device 30. In this case, the setting support unit 232 receives setting values ​​for each lighting fixture 10 from the setting information input device 30 and records the received values ​​in the setting information storage unit 224.

[0030] The setting support unit 232 may transmit, to the setting information input device 30, graphical user interface data for changing the illuminance for each lighting set or each group, for example. In this case, the setting support unit 232 may receive information indicating a change in the settings caused by a user operation on the graphical user interface (information about the settings assigned for each lighting set or each group) from the setting information input device 30. The setting support unit 232 calculates the setting values ​​for each lighting set or each individual lighting fixture 10 included in each group based on the received information and records the calculated values ​​in the setting information storage unit 224. Note that the setting values ​​for each lighting set or each individual lighting fixture 10 included in each lighting set or each group may be calculated in the setting information input device 30. In this case, the setting support unit 232 receives the setting values ​​for each lighting fixture 10 from the setting information input device 30 and records the received values ​​in the setting information storage unit 224.

[0031] The lighting control unit 233 controls the illuminance and color tone of each lighting fixture 10 based on the setting information stored in the setting information storage unit 224. When setting information input device 30 or a switch (not shown) inputs information indicating whether a lighting fixture 10 should be powered on or off, the lighting control unit 233 controls the power on or off of each lighting fixture 10 based on the input information.

[0032] 4 is a diagram showing a specific example of the functional configuration of the setting information input device 30. The setting information input device 30 is configured using information equipment such as a smartphone, tablet, personal computer, dedicated device, etc. The setting information input device 30 includes a communication unit 31, an operation unit 32, a display unit 33, a storage unit 34, and a control unit 35.

[0033] The communication unit 31 is a communication device. The communication unit 31 may be configured as, for example, a network interface. The communication unit 31 communicates data with other devices via the network 90 in accordance with the control of the control unit 35. The communication unit 31 may be a device that performs wireless communication or a device that performs wired communication.

[0034] The operation unit 32 is configured using existing input devices such as a keyboard, a pointing device (mouse, tablet, etc.), buttons, a touch panel, etc. The operation unit 32 is operated by a user when inputting user instructions to the setting information input device 30. The operation unit 32 may be an interface for connecting an input device to the setting information input device 30. In this case, the operation unit 32 inputs an input signal generated in the input device in response to a user input to the setting information input device 30. The operation unit 32 may be configured using a microphone and a voice recognition device. In this case, the operation unit 32 performs voice recognition on words spoken by the user and inputs character string information of the recognition result to the setting information input device 30. The operation unit 32 may be configured in any way as long as it is capable of inputting user instructions to the setting information input device 30.

[0035] Display unit 33 is an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. Display unit 33 displays a graphical user interface for setting the illuminance and color tone of lighting device 10. Data for the displayed graphical user interface may be pre-stored in storage unit 34 or may be provided from dimming control device 20 via network 90. ​​Display unit 33 may also be an interface for connecting an image display device to setting information input device 30. In this case, display unit 33 generates a video signal for displaying image data and outputs the video signal to the image display device connected to display unit 33.

[0036] The storage unit 34 is configured using a storage device such as a magnetic hard disk drive, a semiconductor storage device, etc. The storage unit 34 stores information used by the control unit 35.

[0037] The control unit 35 is configured using a processor such as a CPU and a memory. The control unit 35 functions as a communication control unit 351 and a display control unit 352 when the processor executes a program. All or part of the functions of the control unit 35 may be realized using hardware such as an ASIC, PLD, or FPGA. The above program may be recorded on a computer-readable recording medium. Examples of computer-readable recording media include portable media such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, and a semiconductor storage device (e.g., an SSD), as well as storage devices such as a hard disk or semiconductor storage device built into a computer system. The above program may be transmitted via a telecommunications line.

[0038] The communication control unit 351 controls communication with the dimming control device 20 via the communication unit 31. For example, the communication control unit 351 receives data from the dimming control device 20 and passes the received data to the display control unit 352. For example, the communication control unit 351 transmits the data passed from the display control unit 352 to the dimming control device 20.

[0039] The display control unit 352 displays a user interface screen on the display unit 33 based on graphical user interface data obtained from the storage unit 34 or the dimming control device 20. The display control unit 352 obtains operation information indicating the results of operations performed by the user on the displayed user interface via the operation unit 32, and passes information obtained in response to the operation information to the communication control unit 351. This information is transmitted to the dimming control device 20 by the communication control unit 351. The display control unit 352 may calculate individual setting values ​​for each lighting fixture 10 in response to input values ​​for each lighting set or each group input in response to user operations. In this case, the calculated values ​​are transmitted to the dimming control device 20 by the communication control unit 351.

[0040] 5 is a diagram showing a specific example of a graphical user interface displayed on the display unit 33. The screen displays one or more template buttons 41, a map image 42, multiple lighting set images 43, a lighting set management button group 45, a group management button group 46, an illuminance operation area 47, a color tone operation area 48, and a save button 49.

[0041] Each template button 41 is an image that indicates a template. For example, in the example of Fig. 5, a character string indicated by the label information of each template is displayed in an area within each template button 41. Each template button 41 has a different display mode. For example, the color of the area within each template button 41 may be different.

[0042] The map image 42 displays an image showing a map of part or all of the target facility. Images showing lighting fixtures 10 corresponding to their installation locations and images showing lighting sets are displayed within the map image 42. In this embodiment, a lighting set image 43 is displayed for each lighting set. Each lighting set is given a label (identification information), and the label is also displayed within the lighting set image 43. For example, the four lighting fixtures 10 of the lighting set labeled L1 are installed at the position of the lighting set image 43 indicated as L1. The display mode of each lighting set image 43 corresponds to the template set for that lighting set. For example, the lighting set located at the position of the lighting set image 43 displayed in the same display mode as the hanging scroll of the template button 41 has a hanging scroll template set.

[0043] The user can easily set a template for each lighting set by operating the template button 41 and the lighting set image 43. Any specific operation method may be implemented. For example, a template may be set for the lighting set at a position on the lighting set image 43 by dragging the template button 41 to be applied to that position. In this case, the display control unit 352 transmits operation information related to the dragging and information related to the combination of the template and the lighting set to the dimming control device 20 via the communication control unit 351. In response to the received information, the setting support unit 232 of the dimming control device 20 records in the template information storage unit 222 that the specified template will be applied to the specified lighting set.

[0044] The lighting set management button group 45 includes a user interface for performing operations to set multiple lighting sets as a group. For example, the lighting set management button group 45 includes buttons indicating some or all of the lighting sets displayed on the map image 42 (buttons L1 to L8 in FIG. 5), a select all check box, and a create group button. When setting a new group, the user operates the buttons indicating the lighting sets they want to include in the group to select them, and then operates the create group button to create a group that includes the multiple lighting sets that were selected at that time. When the select all check box is selected, all lighting sets displayed on the map image 42 can be selected at once.

[0045] The group management button group 46 includes a user interface for performing operations to manage multiple groups. For example, the group management button group 46 includes buttons (in FIG. 5, buttons G1 to G4) that indicate some or all of the groups displayed on the map image 42, and a group deletion button. When the user wants to delete a group, the user operates the button for the group to be deleted to select it, and then operates the group deletion button to delete one or more groups that were selected at that time.

[0046] Illuminance operation area 47 displays a user interface for operating the illuminance of lighting device 10. For example, a user can set the illuminance of the lighting device 10 being operated by operating operation bar 471, operation bar 472, up button 473, or down button 474. The illuminance value determined by operating the operation bar or button (473, 474) is displayed in illuminance value display area 475. For example, the illuminance may be displayed as a percentage of the maximum illuminance of lighting device 10 (e.g., 0% to 100%), or as an absolute value of the illuminance (gradation value). In the example of FIG. 5, both the percentage and the absolute value are shown. However, only one of the percentage and the absolute value may be displayed.

[0047] The color tone operation area 48 displays a user interface for operating the color tone of the lighting device 10. For example, a user can set the color tone of the lighting device 10 by operating the operation bar 481 or the up button or down button. The color tone value determined in response to the operation of the operation bar or button is displayed in the color tone value display area 482. For example, the color tone may be represented by a color temperature value or another value.

[0048] The save button 49 is a button for setting the illuminance and color tone values ​​currently indicated in the illuminance operation area 47 and color tone operation area 48 for the lighting fixture 10 that is currently being operated. In response to the save button 49 being operated, the display control unit 352 sends information indicating the setting target and information indicating the setting value to the dimming control device 20. The information indicating the setting target may be information indicating an individual lighting fixture 10, a lighting set, or a group. The information indicating the setting value may be a setting value for an individual lighting fixture 10, a value set for the lighting set, or a value set for the group.

[0049] By selecting one or more lighting fixtures 10, one or more lighting sets, or one or more groups, the user can collectively operate (change or set) the illuminance and color tone of the selected lighting fixtures 10, or all the lighting fixtures 10 included in the selected lighting set or group. For example, the user selects a button indicating the lighting fixture, lighting set, or group for which the user wants to set the illuminance and color tone in the map image 42, lighting set management button group 45, or group management button group 46. This operation selects the setting target. The user then operates the illuminance operation area 47 or color tone operation image 48. This operation collectively sets the illuminance for all the lighting fixtures 10 included in the selected lighting set or group. At this time, the relative illuminance relationships (ratios) of all the lighting fixtures 10 included in the selected lighting set or group remain fixed, while the illuminance values ​​are changed. For example, downlights (lighting fixtures 10) may be distributed in a plane, with the illuminance changed at each location, and then the illuminance values ​​may be changed while maintaining the relative relationships (ratios) of each. For example, the illuminance value may be set by fine-tuning each of the lighting fixtures 10 arranged in a line, taking into account the presence or absence of walls or beams for indirect lighting, and then the illuminance value may be changed while maintaining the relative relationship (ratio) between each.

[0050] FIG. 6 is a diagram showing a specific example of a template generation screen. In the example shown in FIG. 6, the left side displays images of each lighting fixture 10 included in a lighting set according to its installation position. The right side displays an illuminance operation area 61 for setting the illuminance and color tone of each lighting fixture 10, a general illuminance operation area 62 for collectively setting the illuminance of all lighting fixtures included in a lighting set, and a general color tone operation area 63 for collectively setting the color tone of all lighting fixtures included in a lighting set. Template information can be generated on this template generation screen. Note that the operation area for setting the color tone (color tone operation area 63) does not necessarily have to be displayed on the template generation screen. In other words, the template generation screen may be configured so that only the illuminance of the lighting fixtures can be collectively set.

[0051] For example, illuminance operation area 61_1 is an illuminance operation area 61 for setting the illuminance of lighting fixture 10_1, illuminance operation area 61_2 is an illuminance operation area 61 for setting the illuminance of lighting fixture 10_2, illuminance operation area 61_3 is an illuminance operation area 61 for setting the illuminance of lighting fixture 10_3, and illuminance operation area 61_4 is an illuminance operation area 61 for setting the illuminance of lighting fixture 10_4. By operating the operation bar in each illuminance operation area 61, it is possible to set the illuminance of lighting fixture 10 corresponding to each illuminance operation area 61. By operating these illuminance operation areas 61, it is possible to set the relative illuminance relationship between each lighting fixture 10 included in the lighting set of the template being generated.

[0052] The overall illuminance operation area 62 is an operation area for changing the overall brightness while maintaining the relative illuminance relationships currently set by each illuminance operation area 61. The overall color tone operation area 63 is an operation area for setting the color tone of each lighting fixture 10 included in the lighting set of this template. By operating the overall color tone operation area 63, the color tone of each lighting fixture 10 included in the lighting set is set to the same value.

[0053] Dimming control system 100 configured in this manner can change the illuminance values ​​of multiple lighting fixtures 10 collectively while maintaining the relative relationships (ratios) between the illuminance values. For example, it is possible to change the illuminance values ​​of each lighting fixture 10 included in a lighting set while maintaining the relative relationships between the illuminance values ​​of each lighting fixture 10. Generally, an optimal lighting environment is achieved by combining multiple lighting fixtures. As described above, the illuminance of multiple lighting fixtures 10 can be changed collectively while maintaining the relative relationships (ratios) between the multiple lighting fixtures in the combination, reducing the labor required for the work and enabling appropriate illuminance settings.

[0054] Furthermore, in the dimming control system 100, by defining a template, it is possible to easily set the illuminance and color tone of each lighting fixture 10 by applying the template to each combination of multiple lighting fixtures (e.g., a lighting set). Furthermore, information indicating the situation in which the template is used can be defined as label information for the template. For example, information indicating the type of exhibit may be provided. Defining templates in this manner makes it possible to easily select a template appropriate for the purpose and set the illuminance of multiple lighting fixtures. Generally, the illuminance of each lighting fixture needs to be adjusted according to the detailed lighting presentation (appearance) of the exhibit. Furthermore, the illuminance of the exhibit is strictly controlled, and detailed illuminance adjustment based on the appearance of the exhibit is essential. Even in such an environment, applying the template of the dimming control system 100 makes it possible to easily set the illuminance according to the exhibit. Note that the specific example of the template shown in FIG. 6 is merely an example, and other types of templates may be defined. For example, a template for wall washer lighting may be defined.

[0055] (Variation) The dimming control device 20 does not necessarily have to be configured as a single device. For example, the dimming control device 20 may be configured using multiple information processing devices. The multiple information processing devices that make up the dimming control device 20 may be communicably connected via a communication path such as a network 90 and configured as a system such as a cluster machine or a cloud. For example, the recording control unit 231 and the setting assistance unit 232 may be realized in a computer installed at a location remote from the target facility via a communication path such as the network 90, and the lighting control unit 233 may be realized in a computer installed in the target facility. In this case, the computer that functions as the lighting control unit 233 may be an information processing device such as a personal computer, or may be realized using a simple information processing device such as a single-board computer. The dimming control device 20 and the setting information input device 30 may be configured as an integrated information processing device.

[0056] When manipulating (changing or setting) the illuminance of multiple lighting devices 10 collectively, the relative illuminance relationships (ratios) of the illuminance of all lighting devices 10 may be fixed, but the relative magnitude relationships between the illuminance of each lighting device 10 may be fixed. For example, the magnitude relationships may be maintained, but the extent or ratio of the change in illuminance of each lighting device 10 may vary depending on the values ​​before and after the change. This will be explained using a specific example. Lighting fixture 10_1: 100% of maximum illumination Lighting fixture 10_2: 80% of maximum illumination Lighting fixture 10_3: 30% of maximum illumination Lighting fixture 10_4: 10% of maximum illumination

[0057] When the illuminance of each lighting fixture is set as shown above, the ratio of 10:8:3:1 may be changed while maintaining the relative magnitude. For example, if the illuminance of these four lighting fixtures 10 is lowered, the values ​​may be changed as follows: Lighting fixture 10_1: 50% of maximum illumination Lighting fixture 10_2: 45% of maximum illumination Lighting fixture 10_3: 22% of maximum illumination Lighting fixture 10_4: 8% of maximum illumination

[0058] Although an embodiment of the present invention has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and includes designs within the scope of the gist of the present invention. [Explanation of symbols]
