Description

Systems, methods and kits to prevent insects from entering a given area

The present invention relates to a system, a method, and a kit for preventing the invasion of insects into a predetermined area. More specifically, low insect or insect repellent light in which the wavelength region in which the insect exhibits phototaxis is excluded and insect light in the wavelength region in which the insect exhibits phototaxis are combined to prevent the insect from invading a predetermined region. Regarding systems, methods, and kits to prevent.

It is generally known that insects have the property of moving toward the stimulus of light, that is, phototaxis, and many methods and devices for attracting and exterminating insects using this property have been proposed, and sports facilities. , Stadiums, stores, factories, etc.
However, in recent years, it has been suggested that artificially exterminating insects is not desirable from the viewpoint of conservation of natural ecosystems.

On the other hand, an LED lamp (for example, Patent Document 1) that emits low insect attracting light that does not include wavelengths in the ultraviolet region or insectproof light that does not include wavelengths in the ultraviolet region and visible light region that insects are sensitive to, and insects are sensitive. Using a film, sheet, cover, yellow colorant, etc. that blocks light in the wavelength range, low insect attracting light or insect resistant light is extracted from the light emitted from fluorescent lamps, metal halide lamps, LED lamps, etc. (For example, Patent Documents 2 to 6) have been proposed and used.
Methods and devices that utilize these low insect attracting or insect repellent light sources are desirable means from the viewpoint of conservation of natural ecosystems because they prevent insects from being actively attracted and reduce the invasion of insects into a predetermined place. ..
However, in the methods and devices using these low insect repellent or insect repellent light sources, the insects react to a slight light stimulus when there is no other light source around the place where the low insect repellent or insect repellent light source is installed. There is a problem that the number of insects flying around the place where the low insect attracting or insect repellent light source is installed increases.

On the other hand, in the lighting system of the practice field for ball games, a low insect attracting discharge lamp is used as a light source for illuminating the area used by the user, and a blue light metal halide lamp is used as a light source for illuminating the area where the user's hit ball flies. A lighting system characterized by using the above has been proposed (Patent Documents 7 and 8). This system uses an ultraviolet radiation light source with a high insect attracting effect to actively attract and place insects outside the surroundings of the low insect attracting light source, and a method and device for installing only a low insect attracting or insect repellent light source. Provide one solution to the above problem.
However, the blue light metal halide lamp used as a light source for illumination in this system emits ultraviolet rays in all directions of 360 ° (without reflector) or in the range of 180 ° (with reflector), even a lamp having a reflector. It is installed so as to radiate ultraviolet rays toward the outside of the ball game practice area. Therefore, there is a problem of attracting insects unrelated to the purpose of reinforcing the insect attracting effect of the low insect attracting or insect repellent light source. In other words, not only insects that have flown around the low insect or insect repellent light source, but also insects that are outside the ball game practice field are attracted, so the number of insects that fly into the ball game practice field increases, and the metal halide lamp Insects may fly to the area where the user is located when the low insect repellent discharge lamp is in close proximity or when there are many insects in the ball game practice area. In addition, the number of insects flying into the ball game practice area increases, which causes discomfort to the user.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, it should be noted that the present invention is not limited to the embodiments described below, and the technical idea of the present invention may be applied to other embodiments.

As described above, the present invention relates to a system for preventing the invasion of insects into a predetermined area by combining a low insect repellent or insect repellent light source and an insect repellent light source.

The "predetermined area" in the specification of the present application means an area intended to prevent the invasion of insects by the system of the present invention (hereinafter, may be referred to as an "insect-proof area"), such as a factory or a store. In addition to the physical structures of, the surroundings of such structures (backyards, parking lots, etc.), play areas or spectator seating areas of sports facilities, fields, etc. are also included. Therefore, various facilities and spaces can be applied to the "predetermined area". For example, a store such as a supermarket, a convenience store, a restaurant or a part thereof (for example, an entrance / exit) or its surroundings, a facility of various factories such as a food factory or a semiconductor manufacturing factory or a part thereof (for example, an entrance / exit) or its surroundings (for example, a carry-in entrance / exit) For example, a track yard), a house or a part thereof (for example, a doorway) or its surroundings, a place where users of a golf practice field or a batting practice field may exist, a spectator area of a sports facility such as a baseball field or a soccer field. Includes any facility, location or space where it is desired to prevent the invasion of insects, such as fields, near airport runways, bus stops and surroundings, station platforms, etc.

When a physical structure such as a factory or store and the surrounding area of such a structure are designated as an insect repellent area, suppressing the invasion of insects into the surrounding area such as a factory or store means that the insects may enter the factory or store itself. There is a relationship to prevent intrusion more reliably. In this case, prevention of insects from invading the factory or the store itself is required at a higher level, which is different from the level required in the surrounding area. Therefore, in the "predetermined region", regions with different levels required to prevent the invasion of insects may coexist.

In the present specification, "low insect attracting light" means light containing little or no ultraviolet region having a wavelength of 340 nm to 400 nm, and "insect-proof light" means light having almost no ultraviolet region and visible light region having a wavelength of 340 nm to 480 nm. Or it means light that does not contain at all. For example, as shown in FIG. 16, "low insect attracting light" it does not include the 5 W / ^{m 2} or more peaks in the ultraviolet region of wavelength 340 nm ~ 400 nm, preferably free of 2μW / ^{m 2} or more peaks. Further, "insect light" does not include the 5 W / ^{m 2} or more peaks in the ultraviolet region and the visible light wavelength region of 340 nm ~ 480 nm, preferably free of 2μW / ^{m 2} or more peaks.
As a low insect attracting or insect repellent light source, for example,
A neutral white LED light source that emits light that contains little or no wavelength in the ultraviolet region, as shown in FIG. 4A, or emits light that emits light that contains little or no wavelength in the ultraviolet region and the visible light region that has an insect attracting effect. Yellow-green LED light sources (these are directional),
Light emitted from fluorescent lamps, metal halide lamps, LED light sources, etc., as shown in FIG. 4B, is passed through a filter or sheet that cuts the ultraviolet region or the visible light region that has an insect attracting effect, and has low insect attracting or insect repellent light. Light source system,
Fluorescent lamps, metal halide lamps, LED light sources, etc., as shown in FIG. 4C, are covered with a dye (for example, a yellowish dye) that cuts an ultraviolet region or a visible light region having an insect attracting effect to reduce insect attraction or A light source system that emits insect-proof light, and a fluorescent lamp, metal halide lamp, LED light source, etc. as shown in FIG. 4 (d) are covered with a film that cuts an ultraviolet region or a visible light region that has an insect attracting effect to reduce insect attraction. Alternatively, a light source system that emits insect-proof light can be mentioned.

Such a low insect attractant or insect repellent light source is commercially available, and examples of the low insect attractant light source include an ultraviolet radiation cut shatterproof fluorescent lamp FLR40SEX-N / M. Examples include P / NU (manufactured by NEC Lighting Co., Ltd.), Opto Energy Real Color (manufactured by Taisei Fine Chemical Co., Ltd.), and straight tube LED lamp neutral white (model number: LDF10ss ・ D / 6 / 6-U1, manufactured by Ohm Electric Co., Ltd.). Examples of the insect-proof light source include yellow, yellow-green or green lamps, and commercially available products include, for example, pure yellow fluorescent lamp low insect attractant FLR40SY-F / M (manufactured by NEC Lighting Co., Ltd.) and Magic Optron LED (Taisei). (Manufactured by Fine Chemical Co., Ltd.).

We also know a light source that enhances the intensity of low insect attracting light emitted from the phosphor by absorbing blue light or near-ultraviolet light with a peak wavelength of 370 nm to 480 nm into a phosphor that emits yellow light with a peak wavelength of 560 nm to 580 nm as excitation light. (Patent Document 1), and may be used as a low insect attractant light source of the present invention.

A low insect repellent or insect repellent light source provides light in areas where illumination of the insect repellent area is required, while preventing active attraction of insects to the insect repellent area. Therefore, "around the low insect repellent or insect repellent light source" is included in the insect repellent area.
The low insect attractant or insect proof light source can be installed in various places, for example, in a building such as a factory or a store (see (a) in FIG. 3), or in a part of a section or room in the building (Fig. 3 (b)), the boundary between the building and the space outside it (see (c) in Fig. 3), the area around the building (see (d) in Fig. 3), or a driving range or driving range. It can be installed in a specific range of space (see (e) in FIG. 3) that is open to the outside, such as a space used by athletes, a parking lot, and an outdoor sports facility.
In the example of FIG. 3A, the insect repellent area is a building such as a factory or a store, and in the example of FIG. 3B, the insect repellent area is a part or room of a building. Further, in the example of FIG. 3C and FIG. 3D, the insect repellent area is the building and its surroundings. In this example, it is assumed that the area around the building and / or the building is illuminated, but when the area around the building is illuminated with low insect or insect repellent light, the active attraction of insects to the area around the building is suppressed, and as a result. , Insects invasion into the building is suppressed. In this example, it is not essential to install a low insect repellent or insect repellent light source in the building, and there are cases where a low insect repellent or insect repellent light source is not installed in the building. Therefore, these correspond to an example in which a low insect repellent or insect repellent light source is installed in a part of the insect repellent area. Further, in the example (e) of FIG. 3, the insect repellent area is usually a place used by the user.

In the system or the like according to the embodiment of the present invention, the insect repellent light source is installed away from the insect repellent area, and the insect repellent light is emitted toward the insect repellent area. Further, in a system or the like according to another embodiment, the insect attracting light source is installed away from the low insect attracting or insect repellent light source, and the insect attracting light is radiated toward the low insect attracting or insect repellent light source.
As used herein, the term "insect light" means light in the ultraviolet region having a wavelength of 340 to 400 nm, preferably light having a maximum peak wavelength in the range of 340 to 400 nm. The insect attracting light source may be a light source that emits only the ultraviolet region, or may be a light source that emits ultraviolet rays and visible light. The insect attracting light source may also be a light source that is a combination of a light source that emits ultraviolet rays and a light source that emits visible light.
Some insects are highly sensitive to visible light, and by blending visible light with ultraviolet light, it may be possible to more effectively attract various types of insects toward the insect attracting light source.

It is preferable that the insect attracting light source is installed in a place away from the area or a low insect attracting or insect repellent light source so that the insects attracted by the insect attracting light source do not fly to the insect repellent area. From such a point, the distance between the insect attracting light source and the insect repellent region or the low insect attracting or insect repellent light source is preferably 5 m or more, and more preferably 10 m or more.
On the other hand, if the distance from the insect repellent area or the low insect repellent or low insect repellent light source is too large, the intensity of the insect repellent light becomes low and the attracting effect cannot be sufficiently exerted. It is necessary to install it at the distance you can get. In addition, as the distance from the insect repellent area increases, the irradiation range becomes wider even if the insect repellent light source with the same directivity angle is used. (This point will be explained in detail later).
From such a point, the distance between the insect repellent light source and the insect repellent region or the low insect repellent or insect repellent light source is preferably 30 m or less, more preferably 20 m or less, and particularly preferably 15 m or less. Further, depending on the installation environment, it may be 10 m or less.
The distance between the insect attractant light source and the insect repellent area or the low insect attractant or insect repellent light source also determines the reflectance or the intensity of the reflected light of the wall irradiated with the insect attractant light when the insect attractant light is radiated toward a structure such as a building. It is preferable to consider and decide. Specifically, when the intensity of the reflected light is high, the reflected insect attracting light may cause an insect attracting effect. Therefore, a structure such as a building having a reflectance of 10% or less is an object of the present invention. It is preferably selected. For the same viewpoint, when irradiated with insect attracting light to the structure of the building or the like, the peak wavelength intensity of the ultraviolet region of the reflected light at the position of 10cm from the wall 10 .mu.W / m ² or less, preferably 5 W / m ² or less It is preferable to install an insect attracting light source at such a distance.

Here, in the specification of the present application, the distance between the insect repellent light source and the insect repellent region can be determined based on the position closest to the insect repellent light source in the insect repellent region. However, when setting a structure such as a store or a factory and its surroundings as an insect repellent area, the position closest to the insect attracting light source of the structure may be used as a reference. The level of need to prevent the invasion of insects differs between structures such as stores and factories and their surroundings, and the distance to prevent the invasion of insects into the structure is based on the position of the structure with the highest demand. This is because it may be set.

In the system and the like of the present invention, a directional light source is used as the insect attracting light source in order to radiate the insect attracting light toward the whole or a part of the insect repellent area. However, it is sufficient that the directivity is such that the irradiation range can be controlled, and an insect attracting light source having various directivity angles can be used. Generally, an insect attracting light source having a directivity angle of less than 180 ° is selected, an insect attracting light source having a directivity angle of 120 ° or less is preferably selected, and an insect attracting light source having a directivity angle of 60 ° or less is more preferably selected, and 45 ° or less. It is particularly preferable to select the following insect attracting light sources. However, considering the use of commercially available products that are easily available, an insect attracting light source of 45 ° to 120 ° is preferable, and an insect attracting light source of 45 ° to 60 ° is more preferable.

For example, many LEDs having a directivity angle of 45 ° to 120 ° and emitting ultraviolet rays having a peak wavelength of 340 to 400 nm are commercially available, and it is convenient to use these. Examples of such an ultraviolet emitting LED include NVSU233B / NVSU233B-D4 (peak wavelength 365 nm or 385 nm, directivity angle 60 ° or 120 °, manufactured by Nichia Corporation), NCSU276C (peak wavelength 365 nm, directivity angle 120 °, day). Nichia Corporation), CUN66B1B (peak wavelength 365 nm, directional angle 45 °, manufactured by Soul Biosys), CUN66A1B (peak wavelength 365 nm, directional angle 120 °, manufactured by Soul Biosys), and these ultraviolet emitting LEDs Can be combined with one or more. Further, when combining a plurality of LEDs, a plurality of types of LEDs having different characteristics such as peak wavelength and directivity angle may be combined.

Further, as a commercially available insect attracting light source that emits ultraviolet rays and visible light, for example, Musi Hybrid (manufactured by Iida Lighting Co., Ltd.) can be mentioned. Further, as a commercially available light source that emits visible light, which can form an insect attracting light source in combination with a light source that emits ultraviolet rays, for example, the Nu series (manufactured by NEC Corporation) can be mentioned.

The insect attracting light is emitted toward the whole or a part of the insect repellent area, but as shown in FIGS. 7 and 10, the irradiation range of the insect attracting light emitted from one insect attracting light source is the insect attracting light source from the insect repellent area. It depends on the distance of the insect and the direction angle of the insect light source. Therefore, the directivity angle and installation position (distance from the area that prevents the invasion of insects) of the insect attracting light source are appropriately selected according to the target irradiation range so that the insect attracting light is irradiated to the planned range. It is desirable to. Further, the insect attracting light source may be one, but by combining a plurality of insect attracting light sources, it is possible to irradiate a wider area with the insect attracting light. For example, as shown in FIGS. 5, 6, 8 and 9, a plurality of insect attracting light sources can be arranged at predetermined intervals to irradiate the target range with the insect attracting light without omission. At this time, for example, when an insect attracting light source having a large pointing angle such as 120 ° is used as in the embodiments shown in FIGS. 8 and 9, there is an advantage that one light source can irradiate a wide range, but the irradiation range. The light intensity per area of the light source may be small, or it may be difficult to set an appropriate irradiation range. On the other hand, for example, when an insect attracting light source having a small pointing angle such as 45 ° is used as in the embodiments shown in FIGS. 5 and 6, various irradiation ranges including a narrow range can be easily set and the irradiation range can be set easily. There is an advantage that the light intensity per area of the irradiation range is increased, but since one light source cannot cover a wide irradiation range, a relatively large number of insect attracting light sources may be required.

When using a plurality of insect attracting light sources, each light source can be arranged at various positions according to the directivity angle, the target irradiation range, the installation environment, and the like. For example, when a plurality of insect attracting light sources having the same pointing angle are used, typically, as shown in FIGS. 5, 6, 8 and 9, the target irradiation range, and the pointing angle and insect prevention region of the insect attracting light source are used. The insect light source is irradiated in the same direction at regular intervals so that the insect light is irradiated as uniformly as possible without leaking to the target range (so as not to generate an unirradiated area) according to the distance from the target area. Can be arranged to be. In the embodiment shown in FIG. 5, a plurality of insect attracting light sources having a directivity angle of 45 ° at a position of 10 m from the insect repellent region are at equal intervals of 4.1 m (1/2 distance of the irradiation range of one insect attracting light source). It is installed in. As a result, there is no area around the insect repellent area where the insect light is not irradiated, and the insect light emitted from the adjacent insect light source is continuously and uniformly overlapped. Similarly, in the embodiment shown in FIG. 6, a plurality of insect attracting light sources having a directivity angle of 45 ° at a distance of 15 m from the insect repellent region are installed at equal intervals of 6.2 m, whereby the same irradiation is performed. Forming a situation. In the embodiment shown in FIGS. 8 and 9, a plurality of insect attracting light sources having a directivity angle of 120 ° are installed at positions 10 m and 15 m from the insect repellent region, respectively. In this case, since the irradiation ranges of one insect attracting light source are 34.6 m and 52.0 m, respectively, the insect attracting light sources are arranged at intervals of 17.3 m and 26.0 m, respectively. In this embodiment, there is one overlap of the attracting light from the adjacent insect attracting light source, and it is located in the center of the irradiation range. Since this portion has a high light intensity, a facility that particularly wants to prevent the arrival of insects, for example, a carry-in / exit port may be located in this portion.

On the other hand, the insect attracting light sources do not necessarily have to be arranged at equal intervals, and may be arranged at different intervals depending on the situation of the target irradiation range. Further, it is not always necessary to combine insect attracting light sources having the same directivity angle, and insect attracting light sources having different directivity angles may be combined. Therefore, for example, as shown in FIG. 11, it is possible to select an insect attracting light source having a directivity angle smaller than that of the other insect attracting light sources and arrange the insect attracting light sources at both ends at a smaller interval. Further, as shown in FIG. 12, the entire target range is irradiated with an insect attracting light source having a large directivity angle, and in particular, an insect attracting light source having a small directivity angle is used to superimpose the area where insects are to be prevented from flying. It can also be irradiated.

Also, the insect attracting light source does not necessarily have to face the same direction as long as it irradiates the target area. For example, as shown in FIG. 13, the insect attracting light sources at both ends may be installed inward from other insect attracting light sources.

In one embodiment of the present invention, the insect attracting light may be emitted toward the entire insect repellent area or a part thereof. However, even when radiating to a part, it is preferable to radiate to as wide a range as possible. In addition, when a structure such as a store or factory is included in the insect repellent area, it is not necessary to irradiate the structure such as a store or factory with insect attracting light, but even in this case, the insect repellent area is "directed". Corresponds to radiating. Also, in another embodiment of the invention, the insect attracting light is emitted towards a low insect attracting or insect repellent light source. The attracting light from one insect attracting light source emits "toward" the low insect attracting or insect repellent light source whether it is irradiated to one low insect attracting or insect repellent light source or to a plurality of low insect attracting or insect repellent light sources. , Corresponds to.
On the other hand, in the system of the present invention and the like, it is important to prevent the insect attracting light from being emitted toward the space other than the insect repellent area. When such a space increases, insects that have nothing to do with the purpose of reinforcing the insect repellent effect of low insect repellent or insect repellent light are attracted, and there is a possibility that insects may fly to the area intended to prevent invasion. It will be enhanced.

Here, a typical embodiment of the present invention will be described.
FIG. 1 shows an embodiment in which a factory and a truck yard area are set as areas for preventing the invasion of insects. In the embodiment shown in FIG. 1, a plurality of low insect attracting or insect repellent light sources are arranged at regular intervals on the wall having the entrance / exit of the factory, and the area around the factory including the truck yard area is illuminated with the low insect attracting light or the insect repellent light. .. As a result, we try not to actively attract insects around the factory. On the other hand, a plurality of insect attracting light sources are installed at a distance of about 10 to 15 m (7 to 12 m from the truck yard) from the wall having the entrance and exit of the factory. The installed insect attracting light sources all have the same (for example, 45 °) directivity angles and are installed at equal intervals, and emit insect attracting light toward a certain range in and around the factory. As a result, insects that have flown around the factory, including the truck yard area, are attracted to the insect light source in response to the insect light, creating an insect-free environment around the factory, which prevents insects from invading the inside of the factory. It can be prevented more reliably.

FIG. 2 shows an embodiment in which a clean booth provided in the building is set as an area for preventing the invasion of insects. In this embodiment, the inside of the building is an open space with respect to the outside of the building, but a low insect repellent or insect repellent light source and an insect repellent are used to prevent insects from invading the clean booth provided inside the building. The light source is arranged. Low insect attracting or insect repellent light sources are arranged in the clean booth at predetermined intervals to illuminate the inside of the clean booth. The clean booth is provided with an entrance and exit, and the light inside may leak from here, but since the exposed light is low insect attracting or insect repellent light, the exposed light does not actively attract insects. The insect attracting light source is installed 5 to 10 m away from the clean booth, and the insect attracting light is radiated toward the area of the entrance / exit of the clean booth. As a result, the insects that fly near the entrance / exit of the clean booth are attracted to the insect attracting light source in response to the insect attracting light, and it is possible to more reliably prevent the insects from invading the clean booth.

Hereinafter, the present invention will be described based on examples. However, it should be noted that the present invention is not limited to the following examples.

The system according to the present invention was subjected to an insect capture test in order to evaluate the effect of preventing insects from invading a predetermined place.

1. 2019 Insect Capture Test This test was conducted by combining a low insect attracting or insect repellent light source, and an insect attracting light source composed of a UV lamp having various pointing angles or a combination thereof and a neutral white LED, and each light source obtained. The insect repellent prevention rate and the insect repellent rate were calculated from the number of insects caught in the plant. The combinations of light sources in each example and comparative example are shown in the table below.

In the table, the "UV lamp with a directional angle of 45 °" and the "UV lamp with a directional angle of 120 °" are oriented toward an ultraviolet emitting LED lamp (straight tube UV-LED, manufactured by Iida Lighting Co., Ltd.) with a maximum peak wavelength of 365 nm. The lamp is adjusted to angles of 45 ° and 120 °. The "UV lamp with a directivity angle of 180 °" is an ultraviolet fluorescent fluorescent lamp (black light, manufactured by NEC) with a maximum peak wavelength of 365 nm, which is adjusted to a directivity angle of 180 °. It is a lamp that has been used. The wavelength spectrum of each UV lamp is shown in FIG.

In the table, the "neutral white LED" is a neutral white LED lamp (model number: LDF10ss ・ D / 6 / 6-U1, manufactured by Ohm Electric Co., Ltd.) that emits light in the visible light region. In Examples 3 and 4 and Comparative Example 2, a "UV lamp" and a "neutral white LED" are combined to form an "insect attracting light source". Each insect attracting light source is adjusted so that the light intensity at each wavelength measured at a position 10 m from the light source is substantially the same. The wavelength spectrum of each insect attracting light source is shown in FIG.

In the table, "UV cut neutral white LED" is a neutral white LED lamp (model number: LDF10ss ・ D / 6 / 6-U1, manufactured by Ohm Electric Co., Ltd.) that does not emit ultraviolet rays of 340 to 400 nm, and is used as a low insect attractant light source. Has been done. The "yellow-green insect-proof LED" is a yellow-green insect-proof LED lamp (Magic Optron LED, manufactured by Taisei Fine Chemicals Co., Ltd.) that emits almost no light in the visible light region and 340 to 480 nm ultraviolet rays, and is used as an insect-proof light source. There is. The wavelength spectra of the neutral white LED lamp and the insect-proof LED lamp are shown in FIG.

The insect capture test was carried out using the lighting device 12 shown in FIG. Each of the above-mentioned light sources 14 is incorporated in this device, and insects are captured by adhesive sheets 13 attached to both sides. In the test, the lighting device 12 was placed on the corrugated cardboard 17 and used.
As shown in FIG. 18, first, the above-mentioned low insect attracting or insect repellent light source (not shown) was incorporated into this lighting device, and two units were arranged in the field at intervals of 10 m. A blackout curtain 18 was set up at an intermediate point 5 m away from each lighting device 15 to prevent light from each lighting device 15 from leaking to the other lighting device side 15. Next, a lighting device 16 incorporating each insect attracting light source was arranged at a distance of 10 m or 15 m so as to face one of the two lighting devices 15. The other one did not confront the lighting device 16 incorporating the insect attracting light source. All the installed light sources were turned on for about 10 minutes, and insects were captured by the adhesive sheet attached to each lighting device. After that, the lighting device 16 having an insect attracting light source was moved and confronted with another lighting device incorporating a low insect attracting or insect repellent light source (the arrangement of each lighting device at the time of the first lighting is shown on the left side of FIG. 18; The arrangement of each lighting device at the time of the second lighting is shown on the right side of FIG. 18). All the installed light sources were turned on for about 10 minutes, and the number of insects captured by each lighting device was counted for a total of 20 minutes of the two lights. The test was conducted twice in July and September 2019, and the number of captured insects was calculated as an average value. The insect attraction prevention rate and the insect attraction rate were calculated by the following mathematical formulas.

[Number 1]
Insect attraction prevention rate (%) = [1- (A / B)] x 100
[Number 2]
Insect attraction rate (%) = (C / B) x 100
In the formula, A indicates the number of insects caught by the lighting device having a low insect attracting or insect repellent light source facing the lighting device having an insect attracting light source. B indicates the number of insects caught by the lighting device having a low insect attracting or insect repellent light source that does not confront the lighting device having the insect attracting light source. C indicates the number of insects caught by the lighting device equipped with the insect attracting light source.
The test results of each example and comparative example are summarized in the table below.

As shown in the above test results, it was confirmed that the insect attraction rate increased as the directivity angle of the UV lamp increased. It is understood that this is due to attracting more insects by increasing the range of irradiation with the insect attracting light. Further, even when a UV lamp having a directivity angle of 45 ° was used (Examples 1 and 7), the larger the distance from the low insect attracting or insect repellent light source, the higher the insect attracting rate, but this also increased the distance. Therefore, it is understood that more insects were attracted because the irradiation range became wider. On the other hand, looking at the insect repellent inhibition rate, the insect repellent inhibition rate is higher and lower when the UV lamps with directivity angles of 45 ° and 120 ° are used than when the UV lamps with directivity angles of 180 ° are used. Insect attracting or insect repellent Indicates that more insects near the light source can be attracted.

2. 2020 Insect capture test In this test, assuming that the insect repellent area contains a structure, the insect repellent prevention rate and the insect repellent rate were investigated for the installation conditions of the blackout curtain and the insect repellent light source provided assuming the structure. .. The test conditions in each Example and Comparative Example are as follows.

In the table, the "UV lamp with a directional angle of 45 °" and the "UV lamp with a directional angle of 80 °" are UV-radiating LED lamps (straight tube UV-LED, manufactured by Iida Lighting Co., Ltd.) with a maximum peak wavelength of 365 nm. The lamp is adjusted to 45 ° and 80 °. In addition, an insect repellent LED lamp (Magic Optron LED, manufactured by Taisei Fine Chemical Co., Ltd.) was used as a low insect repellent or insect repellent light source.
In addition, the test procedure of each Example and Comparative Example was basically the same as that of the 2019 test. When using the lighting device shown in FIG. 17 and first arranging two lighting devices incorporating the above-mentioned low insect attractant or insect repellent light source in the field at intervals of 10 m and installing a blackout curtain assuming a structure, Immediately behind each low insect or insect repellent light source, a 4.1 m or 8.2 m blackout was placed so that each low insect or insect repellent light source was located at the midpoint of the width of the blackout. Next, a blackout curtain was set up at an intermediate point 5 m away from each illuminating device on a straight line between the two illuminating devices to prevent light from each illuminating device from leaking to the other illuminating device side. Next, in Examples 8 to 14, lighting devices incorporating each insect attracting light source were arranged at a distance of 10 m or 5 m so as to face one of the two lighting devices. On the other hand, in Comparative Example 4, the lighting device incorporating the insect attractant light source was installed in the direction opposite to the low insect attractant or insect repellent light source without facing the low insect attractant or insect repellent light source. All the installed light sources were turned on for about 10 minutes, and insects were captured by the adhesive sheet attached to each lighting device. After that, the lighting device having the insect attracting light source was moved and confronted with another lighting device incorporating a low insect attracting or insect repellent light source (arrangement of each lighting device at the time of the first lighting and each lighting device at the time of the second lighting). The arrangement of is the same as the arrangement shown in FIG. 18). All the light sources installed in the same manner were turned on for about 10 minutes, and the number of insects captured by each lighting device was counted for a total of 20 minutes of the two lightings. The test was conducted twice in August 2020, and the number of captured insects was calculated as an average value. In addition, the insect attraction inhibition rate and the insect attraction rate were calculated by the above mathematical formulas in the same manner as in the 2019 test.
The test results of each example and comparative example are shown below.

From the above test results, the configuration of Example 8 in which the insect attracting light is irradiated within the range of the dark curtain provided assuming the structure is the configuration and structure of Example 9 in which the insect attracting light is irradiated even outside the range of the dark curtain. It is understood that the insect attraction prevention rate is slightly higher and the insect attraction rate is significantly reduced as compared with the configuration of Example 10 in which the blackout curtain is not provided assuming an object. Further, in the configuration of Comparative Example 4 in which the insect attracting light source is not confronted with the low insect attracting or insect repellent light source and is directed in the direction opposite to the low insect attracting or insect repellent light source, the insect attracting inhibition rate becomes a low value close to the control, and the insect attracting rate is high. It rose significantly.
Further, the configuration of Example 13 in which the insect attracting light source having a directivity angle of 80 ° irradiates the insect attracting light within a substantially range of a blackout curtain having a width of 8.2 m is an insect attracting light source having a directivity angle of 45 ° and a width of 4. Compared with the configuration of Example 11 in which the insect attracting light was irradiated within a substantially range of a 1 m dark curtain, the insect attracting inhibition rate was slightly reduced and the insect attracting rate was slightly increased. It is considered that this is because the directivity angle of the insect attracting light source is increased and the irradiation space of the insect attracting light is expanded. On the other hand, the configuration of Example 13 had the same insect attraction prevention rate as that of Example 14 having the same configuration as that of Example 13 except that a blackout curtain assuming a structure was not provided, but the insect attraction rate was higher. It has decreased. It was confirmed that the insect repellent effect can be enhanced by irradiating the structure with the insect attracting light even when the directivity angle of the insect attracting light source is increased.

These test results show that according to the system of the present invention, it is possible to more effectively prevent the invasion of insects into a predetermined area without attracting insects that do not originally need to be attracted as much as possible.
