[0013] <Embodiment> 1 shows an example of a functional configuration of a light source selection device 100 according to the present embodiment. The light source selection device 100 according to the present embodiment selects light source specifications capable of effectively suppressing attraction of insects for the light source of a lighting fixture to be used at a construction site. In this embodiment, the type of light source used in the lighting fixture is not particularly limited, but examples include LEDs, mercury lamps, and sodium lamps.

[0014] The functions of the light source selection device 100 in the figure are realized by causing a CPU (Central Processing Unit) included in the light source selection device 100 as hardware to execute a program. The light source selection device 100 in the figure includes a user interface unit 101, a control unit 102, and a storage unit 103.

[0015] The user interface unit 101 is a part that realizes a user interface function by a device corresponding to a user interface. The hardware corresponding to the user interface unit 101 may include, for example, input devices such as a mouse and a keyboard, and output devices such as a display device. The hardware corresponding to the user interface unit 101 may also include a touch panel that allows operations on the display surface of a display device.

[0016] The control unit 102 executes various controls in the light source selection device 100. The control unit 102 includes a specification unit 121 and a selection unit 122.

[0017] The identification unit 121 identifies the classification of insects that are most likely to be attracted to the lighting (amount of insects attracted) in the period when the construction work (target construction work) for which the light source is selected is being carried out, based on the time-corresponding insect attracting information (an example of first insect attracting information) stored in the time-corresponding insect attracting information storage unit 131. The amount of insects attracted indicates the amount of insects attracted to the lighting under a combination of a predetermined unit volume, unit time, and unit amount of light. The amount of insects attracted may indicate the weight of insects, or may indicate the number of insects. The classification of insects identified by the identification unit 121 is hereinafter also referred to as a "target insect classification" since it is a target for reducing the amount of insects attracted.

[0018] The selection unit 122 selects the specifications of the light source that can most effectively suppress the amount of insects attracted to the target insect classification. Specifically, the selection unit 122 selects the wavelength of the light source and the blinking frequency of the light source as the specifications of the light source that can most effectively suppress the amount of insects attracted.

[0019] The storage unit 103 stores various information corresponding to the light source selection device 100. The storage unit 103 includes a season-corresponding insect attracting information storage unit 131, a wavelength-corresponding insect attracting information storage unit 132, and a frequency-corresponding insect attracting information storage unit 133.

[0020] The time-corresponding insect attracting information storage unit 131 stores time-corresponding insect attracting information. The time-corresponding insect attracting information is information indicating the amount of insects attracted by each predetermined insect species according to the change in time in a year (yearly unit).

[0021] 2A shows an example of the time-based insect attracting information. The time-based insect attracting information in the figure shows the amount of insects attracted for each predetermined insect classification for each month from May to September. In addition, the seasonal insect attraction information in the figure shows an example in which the amount of insects attracted for each insect classification is treated as zero, since the amount of insects attracted for January to April and October to December is considerably small for each insect classification. For this reason, the seasonal insect attraction information in the figure does not show the amount of insects attracted for January to April and October to December. Specifically, in this embodiment, an example is given in which five insect classifications, "stink bugs and plant hoppers," "bees and winged ants," "flies and midges," and "butterflies," are defined. In the figure, for example, the amount of attracted insects for the five insect classifications "stink bugs / planthoppers," "bees / winged ants," "flies / midges," and "butterflies" in May is shown as S11, S21, S31, S41, and S51, respectively.

[0022] The amount of insects attracted by each insect classification shown in the time-based insect-attracting information may depend on the region. In other words, the time-based insect-attracting information may be created based on the amount of insects attracted measured in the region where the target construction work is performed. Alternatively, the time-based insect-attracting information may be created in accordance with the environmental type to which the region where the target construction work is performed corresponds.

[0023] Returning to Fig. 1 for explanation, the wavelength-corresponding insect attracting information storage unit 132 stores wavelength-corresponding insect attracting information (an example of second insect attracting information). The wavelength-corresponding insect attracting information is information indicating the amount of insects attracted for each insect classification in association with each predetermined wavelength for the light source.

[0024] Fig. 2(B) shows an example of wavelength-corresponding insect attracting information. The wavelength-corresponding insect attracting information in the figure shows an example of storing the amount of insects attracted by each insect classification corresponding to four wavelength ranges (wavelength regions): "400mm-500mm", "500mm-600mm", "600mm-700mm", and "700mm-800mm". In the figure, for example, the insect attraction amounts for five insect classifications, "stink bugs and plant hoppers," "bees and winged ants," "flies and midges," and "butterflies," corresponding to the wavelength range of "400 mm to 500 mm" are shown as L11, L21, L31, L41, and L51, respectively.

[0025] Returning to Fig. 1, the frequency-corresponding insect attracting information storage unit 133 stores frequency-corresponding insect attracting information (an example of third insect attracting information). The frequency-corresponding insect attracting information is information indicating the amount of insects attracted for each insect classification in association with each lighting frequency of the light source.

[0026] Fig. 2(C) shows an example of frequency-corresponding insect attracting information. The wavelength-corresponding insect attracting information in the figure shows an example in which the amount of insects attracted for each insect classification is stored in correspondence with six lighting frequencies, namely "1Hz", "2Hz", "5Hz", "10Hz", "20Hz", and "50Hz". Note that the frequency-corresponding insect attracting information may be made to indicate the amount of insects attracted for each insect classification in correspondence with a range of a predetermined lighting frequency. In the figure, for example, the insect attraction amounts for five insect classifications, "stink bugs and plant hoppers," "bees and winged ants," "flies and midges," and "butterflies," corresponding to a wavelength range of "1 Hz" are shown as F11, F21, F31, F41, and F51, respectively.

[0027] An example of a processing procedure executed by the light source selection device 100 of this embodiment in response to the selection of a light source will be described with reference to the flowchart of FIG. Step S100: In the light source selection device 100, the identification unit 121 acquires the time when the lighting fixture is used in the target construction (lighting use time). The lighting use time may be, for example, the construction period of the target construction (the period from the start date to the end date). Alternatively, the lighting use time may be, for example, a predetermined period during the construction period of the target construction when the amount of insects attracted is predicted to be the highest. The specifying unit 121 may acquire the lighting use time input to the light source selection device 100 by a user's operation on the user interface unit 101, for example.

[0028] Step S102: The identification unit 121 refers to the season-corresponding insect attracting information stored in the season-corresponding insect attracting information storage unit 131 to identify the insect classification that attracts the largest amount of insects during the lighting use period acquired in step S100 as the target insect classification.

[0029] Step S104: The selection unit 122 refers to the wavelength-corresponding insect attracting information stored in the wavelength-corresponding insect attracting information storage unit 132, identifies the wavelength that attracts the smallest amount of insects of the target insect classification identified in step S102, and sets the identified wavelength as the selected wavelength.

[0030] Step S106: The selection unit 122 refers to the frequency-corresponding insect attracting information stored in the frequency-corresponding insect attracting information memory unit 133, identifies the blinking frequency that attracts the least amount of insects of the target insect classification identified in step S102, and sets the identified blinking frequency as the selected frequency.

[0031] Step S108: The selection unit 122 outputs light source selection information. The light source selection information includes the selected wavelength identified in step S104 and the selected frequency identified in step S106. The light source selection information may further include the target insect classification identified in step S102. The selection unit 122 may output the light source selection information by, for example, displaying or printing.

[0032] According to the processing procedure example of FIG. 3, first, in step S102, an insect classification (target insect classification) that attracts the largest amount of insects during the target construction period is identified. Then, in steps S104 and S106, a wavelength and a lighting frequency that can most effectively suppress the amount of insects attracted to the target insect classification are selected. That is, depending on the processing procedure example of FIG. 3, it is possible to effectively suppress the attraction of insects included in the target insect classification that attracts the largest amount of insects during the period when the target construction is performed. As a result, the construction staff can grasp the specifications (wavelength, blinking frequency) of the light source that can effectively suppress the amount of insects attracted during the period (season) corresponding to the construction period. Then, at the actual site of the target construction, a light source with the specifications (wavelength, blinking frequency) indicated by the light source selection information is adopted for the lighting fixture, so that the amount of insects attracted during the construction period can be effectively suppressed.

[0033] <Modification> Modifications of the present embodiment will be described below. The modifications described below may be combined as appropriate.

[0034] [First Modification] In the above embodiment, the type of light source used in the lighting fixture is fixed to a certain type. For example, even if the insects are of the same insect classification, the amount of insects attracted may differ depending on the type of light source. Therefore, in this modification, the selected wavelength and the selected frequency can be specified corresponding to each of a plurality of predetermined light source types. In this modification, the light source selection device 100 may store season-corresponding insect attracting information, wavelength-corresponding insect attracting information, and frequency-corresponding insect attracting information for each predetermined light source type. In this modified example, in step S100, the identification unit 121 acquires the light source type (target light source type) used in the lighting fixture along with the lighting use time. In step S102, the selection unit 122 identifies, as the target insect classification, the insect attracting amount that is maximum and that is associated with the time period that corresponds to the lighting use time acquired in step S100, from the time-corresponding insect attracting information corresponding to the target light source type. In step S104, the selection unit 122 may identify, as the selected wavelength, the wavelength that attracts the minimum amount of insects of the target insect classification in the wavelength-corresponding insect attracting information corresponding to the target light source type, and in step S106, identify, as the selected frequency, the blinking frequency that attracts the minimum amount of insects of the target insect classification in the frequency-corresponding insect attracting information corresponding to the target light source type.

[0035] [Second modified example] The change in the amount of insects attracted according to the time of year depends specifically on the temperature during the corresponding time. In consideration of this point, it is also possible to classify the time periods in the time-based insect attracting information based on temperature, rather than classifying the time periods according to the calendar, such as by month, for example.

[0036] Fig. 4 shows an example of insect-attracting information corresponding to seasons, in which seasons are divided based on temperature. In the insect-attracting information corresponding to seasons in the figure, the seasons are divided into seven seasons: "pre-peak 1", "pre-peak 2", "pre-peak 3", "peak", "post-peak 1", "post-peak 2", and "post-peak 3". In the figure, the temperature divisions corresponding to each of the seven seasons are shown. The seasonal insect attraction information in the figure corresponds to the case where the amount of insects attracted to any category is zero at temperatures below 10°C. For this reason, the seasonal insect attraction information does not show the period corresponding to temperatures below 10°C. In this case, in step S100, the identification unit 121 obtains the predicted temperature corresponding to the period when the lighting is used, and in step S102, the selection unit 122 determines the period to which the temperature obtained in step S100 corresponds, and may determine as the target insect classification the insect classification that attracts the greatest amount of insects from among the insect classifications associated with the determined period.

[0037] [Third Modification] The time-corresponding insect attracting information storage unit 131 may store time-corresponding insect attracting information corresponding to various regions, environmental types, etc., and then use the time-corresponding insect attracting information corresponding to the region and environmental type of the target construction site when selecting a light source. Similarly, for the wavelength-corresponding insect attracting information and the frequency-corresponding insect attracting information, information corresponding to various regions, environmental types, etc. may be stored, and then the information corresponding to the region and environmental type of the target construction site may be used.

[0038] [Fourth Modification] In the above embodiment, the wavelength and the blinking frequency are selected as the specifications of the light source, but in this modified example, either the wavelength or the blinking frequency may be selected as the specifications of the light source.

[0039] [Fifth Modification] In the above example, the case where construction work is the target is taken as an example, but the configuration in the above embodiment may also be applied to a case where lighting equipment is used for an outdoor event, for example.

[0040] [Sixth Modification] The function of the light source selection device 100 may be configured as an insect attracting prediction system distributed among a plurality of devices or servers. For example, the light source selection device 100 may be distributed among a user terminal having a user interface unit 101 and a server having a control unit 102 and a storage unit 103. In this case, the light source selection device 100 may be distributed among a server having the function of the control unit 102 and a server having the function of the storage unit 103.

[0041] In addition, a program for realizing the functions of the light source selection device 100 described above may be recorded in a computer-readable recording medium, and the program recorded in the recording medium may be read into a computer system and executed to perform the processing of the light source selection device 100 described above. Here, "reading a program recorded in a recording medium into a computer system and executing it" includes installing the program into a computer system. The "computer system" here includes hardware such as an OS and peripheral devices. The "computer system" may also include a plurality of computer devices connected via a network including a communication line such as the Internet, a WAN, a LAN, or a dedicated line. The "computer-readable recording medium" refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, or a CD-ROM, and a storage device such as a hard disk built into a computer system. In this way, the recording medium storing the program may be a non-transient recording medium such as a CD-ROM. The recording medium also includes a recording medium provided inside or outside the computer system that can be accessed from a distribution server in order to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program in a format executable by a terminal device. That is, as long as it can be downloaded from a distribution server and installed in a form executable by a terminal device, the format in which it is stored in the distribution server does not matter. The program may be divided into multiple parts, downloaded at different times, and then combined on the terminal device, or each of the divided programs may be distributed by a different distribution server. Furthermore, the "computer-readable recording medium" includes a program that holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that becomes a server or a client when a program is transmitted via a network. The program may also be a program for realizing part of the above-mentioned functions. Furthermore, the program may be a so-called difference file (difference program) that can realize the above-mentioned functions in combination with a program already recorded in the computer system.

[0042] The "Sustainable Development Goals (SDGs)" are 17 international goals that were adopted at the United Nations Summit in September 2015. The light source selection device and insect attracting prediction system according to this embodiment can contribute to the achievement of the 17 SDGs, for example, goal 15, "Protect and preserve the richness of land."
