Description

Systems, methods and kits for preventing the infestation of insects into an area

The present invention relates to systems, methods, and kits for preventing the infestation of insects into an area. More specifically, a system for preventing the invasion of insects into a predetermined area by combining the low larvae or insect repellent light in which the wavelength region in which the insect main light is removed and the larva light in the wavelength region in which the insect exhibits the main light property , methods, and kits.

It is generally known that insects have the property of moving toward the stimulus of light, i.e., having a photoluminescence property, and many methods and devices for attracting and controlling insects using this property have been proposed. It is used in various places.

However, in recent years, the idea that artificially exterminating insects is undesirable from the viewpoint of conservation of natural ecosystems has appeared.

On the other hand, an LED lamp that emits low caterpillar light that does not contain a wavelength in the ultraviolet region or insecticide light that does not include a wavelength in the ultraviolet region and the visible region to which insects are sensitive (for example, Patent Document 1), and insects Using a film, sheet, cover, or a yellow colorant that blocks light in the sensitive wavelength region, low larvae or insect repellent light is extracted from light emitted from fluorescent lamps, metal halide lamps, LED lamps, etc., and this is used as a light source Methods and apparatuses (for example, Patent Documents 2 to 6) have been proposed and used.

The method and apparatus using these low larvae or insect repellent light sources are preferable from the viewpoint of conservation of the natural ecosystem, since they prevent insects from being actively attracted and thereby reduce the invasion of insects into a predetermined place.

However, in the method and apparatus using these small larvae or insect repellent light sources, when other light sources do not exist around the place where the small larvae or insect repellent light source is installed, the insect reacts to a minute light stimulus, There is a problem in that the number of insects flying around the place where the insect repellent light source is installed increases.

In contrast, in the lighting system of the ball game practice ground, a low larval discharge lamp is used as a light source for lighting the area used by the user, and a blue light metal halide lamp is used as a light source for lighting the area where the user's batted ball is flying, characterized in that A lighting system has been proposed (Patent Documents 7 and 8). This system is to actively attract and attract insects out of the surroundings of the low larval light source by using an ultraviolet radiation light source with high larval effect, and one solution to the above problem of the method and apparatus for installing only low larvae or insect repellent light source provide a solution

However, the blue light metal halide lamp used as a light source for lighting in this system emits ultraviolet rays in an omnidirectional range of 360° (without a reflector) or in a range of 180° (with a reflector), and even a lamp with a reflector is outside the ball game practice field It is installed to radiate ultraviolet rays toward the For this reason, there is a problem of attracting insects that are not related to the purpose of reinforcing the larval suppression effect by the low larvae or the insect repellent light source. That is, not only insects flying around the low larvae or insect repellent light source, but also insects outside the ball game practice area are attracted, so the number of insects flying in the ball game practice area increases, and the metal halide lamp and low larva discharge lamp In the case of proximity, or when there are many insects in the practice field for ball game, insects may fly to the area where the user is located. Moreover, since the insects flying in the practice field for ball games increase, it will cause discomfort to a user.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described, referring drawings. However, this invention is not limited to embodiment described below, It should be noted that the technical idea of this invention is applicable also to other embodiment.

The present invention, as described above, relates to a system and the like for preventing insects from entering a predetermined area by a combination of a low larva or insect repellent light source and a larval light source.

The "predetermined area" in this specification means the area where the prevention of insect invasion is intended by the system of this invention etc. (Hereinafter, it may be called "insect repellent area"), and a factory, a store, etc. In addition to the physical structure of the building, it includes the perimeter of such a structure (backyard, parking lot, etc.), the play area or audience area of a sports facility, and spaces such as pavement. Accordingly, the "predetermined area" may correspond to various facilities and spaces. For example, stores such as supermarkets, convenience stores, restaurants, or parts thereof (eg, entrances) or around them, facilities of various factories such as food factories or semiconductor manufacturing plants, or parts thereof (eg, entrances and exits) or Around it (eg a truck yard), a house or a part thereof (eg an entrance) or around it, a place where users of a golf driving range or batting driving range may exist, and the audience area of a sports facility such as a baseball field or a soccer field It includes all facilities, places and spaces where it is desirable to prevent insect infestation, such as , pavements, near runways at airports, bus stops and their surroundings, and station platforms.

When physical structures such as factories and stores and the periphery of such structures are used as insect repellent areas, suppressing the invasion of insects into the perimeter of factories and stores more reliably prevents insects from entering the factory or store itself. is in a relationship In this case, it is required at a higher level to prevent the invasion of insects into the factory or store itself, which is different from the level required for its surroundings. Therefore, in the "predetermined area", areas with different levels required to prevent insect invasion may coexist.

In the present specification, "low larvae light" means light that contains little or no ultraviolet region with a wavelength of 340 nm to 400 nm, and "insect light" refers to an ultraviolet region and visible light region with a wavelength of 340 nm to 480 nm. light that contains little or no For example, as shown in FIG. 16 , "low larval light" does not contain a peak of 5 μW/m or more in the ultraviolet region with a wavelength of 340 nm to 400 nm, and preferably contains a peak of 2 μW/m or more. I never do that. In addition, "insect light" does not contain a peak of 5 µW/m 2 or more in the ultraviolet region and the visible region with a wavelength of 340 nm to 480 nm, and preferably does not contain a peak of 2 µW/m 2 or more.

As a low larval or insect repellent light source, for example,

A main white LED light source emitting light that emits light containing little or no wavelength in the ultraviolet region, or light containing little or no wavelength in the ultraviolet region and visible region with a larval effect, as shown in Fig. 4(a) yellow-green LED light sources (they have directivity),

As shown in Fig. 4(b), light emitted from a fluorescent lamp, a metal halide lamp, an LED light source, etc. is passed through a filter or sheet that cuts the ultraviolet region or the visible region with a more larval effect, and low larvae or insect-repellent light radiating light system,

As shown in Fig. 4(c), a fluorescent lamp, a metal halide lamp, an LED light source, etc. is covered with a dye (for example, a yellow dye) that cuts an ultraviolet region or a visible light region having a further larval effect, a light source system that emits insecticide, and

As shown in Fig. 4(d), a light source system that emits low larvae or insect repellent light by covering a fluorescent lamp, a metal halide lamp, an LED light source, etc. with a film that cuts an ultraviolet region or a visible light region with a more larval effect can

Such a low larva or insect repellent light source is commercially available, and examples of the low larval light source include an ultraviolet radiation cut scattering prevention fluorescent lamp FLR40SEX-N/M.P/NU (manufactured by NEC Lighting Co., Ltd.), Opt Energy Real Color ( Daesung Fine Chemicals Co., Ltd. make), and a straight tube LED lamp main white (Model number: LDF10ss*D/6/6-U1, Omni Denki Co., Ltd. make) are mentioned. Moreover, as an insect repellent light source, a yellow, yellow-green, or green lamp is mentioned, As a commercial item, For example, a pure yellow fluorescent lamp low caterpillar FLR40SY-F/M (made by NEC Lighting), Magic Optron LED ( Daesung Fine Chemical Co., Ltd.) is mentioned.

A light source is also known that absorbs blue light or near-ultraviolet light with a peak wavelength of 370 nm to 480 nm to a phosphor emitting yellow light with a peak wavelength of 560 nm to 580 nm as excitation light, thereby increasing the intensity of low larval light emitted from the phosphor ( You may use it as patent document 1) and the low larval light source of this invention.

The low larvae or insect repellent light source brings light to a range where illumination of the insect repellent area is required while preventing active attraction of insects to the insect repelling area from occurring. Therefore, "a small larva or the periphery of the insect repellent light source" is included in the insect repellent area.

The low larvae or insect repellent light source can be installed in various places, and for example, in a building such as a factory or a store (see Fig. 3 (a)), a part of the building or a room (Fig. 3 (b)) )), the boundary between the building and other spaces (see Fig. 3 (c)), the perimeter of the building (refer to Fig. 3 (d)), or the player's use area of the golf driving range or batting driving range, parking lot, outdoor area It can be installed in a space (refer to FIG. 3 (e)) of a specific range that is open to the outside, such as an exercise facility.

In the example of Fig.3 (a), an insect-proof area is a building, such as a factory and a store, In the example of Fig.3(b), an insect-proof area is a part of a division or a room of a building. Moreover, in the example of FIG.3(c) and FIG.3(d), an insect repellent area is a building and its periphery. In this example, it is assumed to illuminate the perimeter of the building and/or the building, but when the perimeter of the building is illuminated with low caterpillars or insecticides, the active attraction of insects to the perimeter of the building is suppressed, and as a result, Intrusion is suppressed. In this example, installation of the low caterpillar or insect repellent light source in the building is not essential, and there is a case where the low caterpillar or insect repellent light source is not provided in the building. Therefore, these correspond to an example in which a low larva or an insect repellent light source is provided in a part of an insect repellent area. In addition, in the example of FIG.3(e), an insect repellent area is a place normally used by a user.

In the system or the like according to one embodiment of the present invention, the larvae light source is installed to be spaced apart from the insect-proof area, and the caterpillar light is radiated toward the insect-proof area. In addition, in the system or the like according to another embodiment, the larval light source is installed to be spaced apart from the low larva or insect repellent light source, and the larval light is emitted toward the low larva or the insect repellent light source.

In this specification, "larva light" means light in the ultraviolet region with a wavelength of 340 to 400 nm, preferably light having a maximum peak wavelength in the range of 340 to 400 nm. As a larval light source, the light source which radiates only the said ultraviolet region may be sufficient, and the light source which radiates ultraviolet and visible light may be sufficient. The larval light source may also be a light source in which a light source emitting ultraviolet light and a light source emitting visible light are combined.

Some insects have high sensitivity to visible light, and by blending visible light with ultraviolet light, various types of insects can be more effectively attracted to the larval light source in some cases.

The installation of the larval light source is preferably performed in a place spaced apart from the area or the small larvae or the insect repellent light source to such an extent that insects attracted to the larval light source do not fly to the insect repellent area. From such a point, it is preferable to set it as 5 m or more, and, as for the distance between a caterpillar light source and an insect repellent area, or a low larva or an insect repellent light source, it is more preferable to set it as 10 m or more.

On the other hand, if it is too far away from the insect repellent area or low larvae or light source, the intensity of the larval light is lowered and the attracting effect cannot be sufficiently exerted. need to install In addition, as the distance from the insect repellent area increases, the irradiation range expands even if a larval light source with the same directivity angle is used. This point will be explained in detail later).

From this point of view, the distance between the larvae light source and the insect repellent region or low larva or the insect light source is preferably 30 m or less, more preferably 20 m or less, and particularly preferably 15 m or less. Moreover, it is good also as 10 m or less depending on an installation environment.

The distance between the caterpillar light source and the insect-repellent area or low larvae or insect-repellent light source is also preferably determined in consideration of the reflectance of the wall to which the caterpillar light is irradiated or the intensity of the reflected light, when radiating the caterpillar light toward a structure such as a building. Specifically, when the intensity of the reflected light is high, there is a possibility that a larval effect may be caused by the reflected larval light, so a structure such as a building having a reflectance of 10% or less is preferably selected as an application target of the present invention. In addition, from the same viewpoint, when larval light is irradiated to a structure such as a building, the peak wavelength intensity of the ultraviolet region of the reflected light is 10 μW/m2 or less at a position of 10 cm from the wall, preferably 5 μW/m2 or less. It is desirable to install a larval light source on the street.

Here, in the present specification, the distance between the larvae light source and the insect repellent region may be determined based on the position closest to the larval light source of the insect repellent region. However, when a structure such as a store or factory and its surroundings are set as an insect repellent area, the determination may be made based on the position closest to the larval light source of the structure. In structures such as stores and factories and their surroundings, the level of necessity to prevent insect invasion is different, and the distance to prevent insect invasion into the structure may be set based on the location of the structure with the highest demand. Because.

In the system or the like of the present invention, a light source having a directivity is used for the caterpillar light source because the caterpillar light is emitted toward the whole or a part of the insect repellent area. Above all, a degree of directivity capable of controlling the irradiation range is sufficient, and a larval light source having various directivity angles can be used. In general, a larval light source with a directing angle of less than 180° is selected, preferably a larval light source with a directing angle of 120° or less, more preferably a larval light source of 60° or less, and a larva of 45° or less It is particularly preferred to select a light source. However, when the use of a commercially available product is considered, a larval light source of 45° to 120° is preferable, and a larval 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 them. Examples of such ultraviolet emitting LEDs include NVSU233B/NVSU233B-D4 (peak wavelength 365 nm or 385 nm, directivity angle 60° or 120°, manufactured by Nichia Chemical Industries, Ltd.), NCSU276C (peak wavelength 365 nm, directivity angle 120°, Nichia Chemical Co., Ltd.), CUN66B1B (peak wavelength 365 nm, directivity angle 45°, Seoul Viosys Corporation make), CUN66A1B (peak wavelength 365 nm, directivity angle 120°, Seoul Viosys Corporation make) are mentioned, These ultraviolet rays One or a plurality of radiating LEDs can be combined. Moreover, when combining several LED, you may combine several types of LED from which characteristics, such as a peak wavelength and a directivity angle, differ.

Moreover, as a commercially available larval light source which emits an ultraviolet-ray and visible light, a disregarding hybrid (made by Iida Illumination Co., Ltd.) is mentioned, for example. Moreover, as a commercially available light source which radiates visible light which can comprise a larval light source in combination with the light source which radiates an ultraviolet-ray, Nu series (made by Hotalux Corporation) is mentioned, for example.

The caterpillar 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 caterpillar light emitted from one caterpillar light source is the distance of the caterpillar light source from the insect repellent area and the caterpillar light source It is determined according to the orientation angle of Therefore, it is preferable to appropriately select the orientation angle and installation position (distance from the area where insect intrusion is prevented) of the larval light source according to the target irradiation range, so that the larval light is irradiated in the predetermined range. Moreover, although one larval light source may be sufficient, it can irradiate larval light to a wider area|region by combining two or more. For example, as shown in FIGS. 5, 6, 8 and 9 , a plurality of larval light sources can be arranged at predetermined intervals, and larval light can be irradiated without missing a target range. At this time, for example, as in the embodiment shown in FIGS. 8 and 9 , if a larval light source having a large directing angle such as 120° is used, there is an advantage that it can be irradiated widely with one light source, but irradiation When the light intensity per area of a range becomes small, or setting of an appropriate irradiation range may become difficult. On the other hand, for example, as in the embodiment shown in FIGS. 5 and 6 , when a larval light source having a small directing angle such as 45° is used, it is easy to set various irradiation ranges including a narrow range and Together, there is an advantage that the light intensity per area of the irradiation range becomes large, but since a single light source cannot cover a wide irradiation range, relatively many larval light sources are sometimes required.

In the case of using a plurality of larval light sources, each light source may be disposed at various positions depending on a directing angle, a target irradiation range, an installation environment, and the like. For example, when using a plurality of larval light sources having the same directing angle, typically, as shown in FIGS. 5, 6, 8 and 9 , the targeted irradiation range, and the directing angle and insect repelling of the larval light source According to the distance from the area, the caterpillar light source is arranged so that the caterpillar light is irradiated in the same direction at equal intervals so that the caterpillar light is irradiated as uniformly as possible within the target range (so as not to create an unirradiated area) can do. In the embodiment shown in FIG. 5 , a plurality of larval light sources having a directivity angle of 45° at a position where the distance from the insect repellent area is 10 m is 4.1 m (distance of 1/2 of the irradiation range of one larval light source) at equal intervals is installed with Thereby, there is no region to which larval light is not irradiated around the insect repellent area, and overlapping of the larval light irradiated from the adjacent larval light sources is continuously and uniformly generated. Similarly, in the embodiment shown in FIG. 6 , a plurality of larval light sources with a directivity angle of 45° are provided at equal intervals of 6.2 m at a position with a distance from the insect repellent area of 15 m, thereby forming the same irradiation situation are doing In the embodiment shown in FIGS. 8 and 9 , a plurality of larval light sources having an orientation angle of 120° are provided at positions 10 m and 15 m from the insect repellent area, respectively. In this case, since the irradiation ranges of one larval light source are 34.6 m and 52.0 m, respectively, the larval light sources are arranged at intervals of 17.3 m and 26.0 m, respectively. In this embodiment, one overlap of larval light from adjacent larval light sources is located at the center of the irradiation range. In this part, since the light intensity becomes large, you may place the facility which wants to prevent the flight of insects especially in this part, for example, a carry-out entrance.

On the other hand, the larval light sources are not necessarily arranged at equal intervals, and may be arranged at different intervals depending on the condition of the target irradiation range. In addition, it is not always necessary to combine the larval light sources of the same directivity angle, and the larval light sources of different directivity angles may be combined. Therefore, for example, as shown in FIG. 11 , it is possible to select a larval light source at both ends of a larval light source having a smaller directivity angle than the other larval light sources, and to arrange the larval light sources at smaller intervals. In addition, as shown in FIG. 12 , the entire target range is irradiated with a larval light source with a large directivity angle, and a larval light source with a small directivity angle is used in the area where you want to prevent the flying of insects in particular. It can also be overlapped.

In addition, when the larval light source is irradiated to the target range, it is not necessarily necessary to face the same direction. For example, as shown in FIG. 13 , the larval light sources at both ends may be provided inwardly rather than the other larval light sources.

In one embodiment of the present invention, larval light may be radiated toward the whole of the insect repellent area, or may be radiated toward a part thereof. However, even when radiating toward a part, it is preferable to radiate toward as wide a range as possible. In addition, when structures such as stores and factories are included in the insect repellent area, it is not necessary to cause caterpillar light to reach the structures such as stores and factories. Moreover, in another embodiment of this invention, caterpillar light is radiated toward a low caterpillar or an insect repellent light source. Even when the larva light from one caterpillar light source is irradiated to one small caterpillar or insect repellent light source, even when irradiated to a plurality of small caterpillars or insect repellent light sources, the small larva or insect repellent light source is emitted "towards", corresponding to do.

On the other hand, in the system or the like of the present invention, it is important to prevent larval light from being emitted toward a space other than the insect repellent area. When such a space increases, insects irrelevant to the purpose of reinforcing the larval deterrent effect of small larvae or insectivorous insects are attracted, thereby increasing the possibility of insects flying to the area intended to prevent intrusion.

Here, a typical embodiment of the present invention will be described.

Fig. 1 shows an embodiment in which factory and truck yard areas are set as areas for preventing insect intrusion. In the embodiment shown in Fig. 1, a plurality of low caterpillars or insect repellent light sources are arranged at regular intervals on the wall having the entrance and exit of the factory, and the periphery of the factory including the truck yard area is illuminated with low caterpillar or insect repellent light. . As a result, it is made not to actively attract insects around the factory. On the other hand, a plurality of larval 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 larval light sources all have the same (for example, 45°) directivity angle, are installed at equal intervals, and emit larval light toward a certain range of the factory and its surroundings. As a result, insects flying around the factory, including the truck yard area, are attracted to the larval light source in response to the caterpillar light, and a more insect-free environment is formed around the factory, thereby preventing insects from invading the inside of the factory. can definitely be prevented.

Fig. 2 shows an embodiment in which a clean booth formed in a building is set as an area for preventing insects from entering. In this embodiment, although the inside of a building is an open space with respect to the exterior of a building, a low larva or insect repellent light source and a larva light source are arrange|positioned so that invasion of insects into the clean booth formed in the building may be prevented. Low larvae or insect repellent light sources are arranged at predetermined intervals in the clean booth and illuminate the inside of the clean booth. In the clean booth, an entrance is formed, and light from the inside may leak from here, but since the light to be exposed is a low larva or insect repellent, insects are not actively attracted by the exposure light. The larval light source is installed 5 to 10 m apart from the clean booth, and larval light is emitted toward the area of the entrance of the clean booth. Thereby, insects flying near the entrance and exit of the clean booth are attracted to the larval light source in response to the larval light, and it is possible to more reliably prevent insects from entering 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.

Example

For the system according to the present invention, in order to evaluate the effect of preventing the invasion of insects into a predetermined place, an insect capture test was carried out.

1. 2019 Insect Capture Test

This test is conducted by combining a low larva or insect light source, and a larval light source composed of a UV lamp having various directivity angles or a combination of it and a main white LED, The arrest rate and larval rate were calculated. The combination of the light sources in each Example and the comparative example is shown in the following table|surface.

In the table, the "UV lamp with a directional angle of 45°" and "UV lamp with a directional angle of 120°" direct an ultraviolet emitting LED lamp (straight tube UV-LED, manufactured by Iida Illumination Co., Ltd.) having a maximum peak wavelength of 365 nm, respectively. A lamp adjusted to an angle of 45° and 120°, and the “UV lamp with a directing angle of 180°” is an ultraviolet emitting fluorescent lamp (Blacklight, manufactured by NEC) having a maximum peak wavelength of 365 nm, adjusted to a directivity angle of 180° one lamp The wavelength spectrum of each UV lamp is shown in FIG.

In the table, "main white LED" is a main white LED lamp (model number: LDF10ss·D/6/6-U1, manufactured by Ohm Electric Co., Ltd.) that emits light in the visible region. In Examples 3 and 4, and Comparative Example 2, "a UV lamp" and a "main white LED" were combined to constitute a "larval light source". Each larval light source is adjusted so that the light intensity at each wavelength measured at a position 10 m from the light source becomes substantially the same. The wavelength spectrum of each larval light source is shown in FIG. 15 .

In the table, "UV cut main white LED" is a main white LED lamp (model number: LDF10ss·D/6/6-U1, manufactured by Ohm Electric Corporation) that does not emit ultraviolet rays of 340 to 400 nm, and is used as a low larval light source. have. In addition, "yellow-green insect repellent LED" is a yellow-green insect repellent LED lamp (Magic Optron LED, manufactured by Daesung Fine Chemicals) that hardly emits light in the 340 to 480 nm ultraviolet and visible region, and is used as an insect repellent light source. The wavelength spectrum of the main white LED lamp and the insect repellent LED lamp is shown in FIG.

The insect capture test was performed using the lighting device 12 shown in FIG. Each of the above-mentioned light sources 14 is attached to this apparatus, and insects are captured by the adhesive sheets 13 laid on both sides. In the test, the lighting device 12 was placed on the corrugated cardboard box 17 and used.

As shown in FIG. 18, first, the above-mentioned low larva or insect repellent light source (not shown) was attached to this lighting device, and it arrange|positioned 2 units|sets at intervals of 10 m during pavement. A blackout curtain 18 was set at an intermediate point 5 m away from each lighting device 15 so that light from each lighting device 15 did not leak to the other lighting device 15 side. Next, one of the two lighting devices 15 was placed opposite to one another, and a lighting device 16 equipped with each larval light source was placed at a distance of 10 m or 15 m. The other one was not replaced with the lighting device 16 equipped with the larval light source. All of the installed light sources were turned on for about 10 minutes, and insects were captured by an adhesive sheet attached to each lighting device. Thereafter, the lighting device 16 having a larval light source was moved and replaced with another lighting device equipped with a low larva 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 ) and the arrangement of each lighting device at the time of the second lighting is shown on the right side of FIG. 18). All of the installed light sources were turned on for about 10 minutes, and the number of insects captured by each lighting device was counted in a total of 20 minutes of the two lightings. The test was conducted twice in July and September of 2019, and the number of captured insects was calculated as an average value. The larval inhibition rate and the larval rate were calculated|required by the formula shown below.

[Equation 1]

Larvae inhibition rate (%) = [1 - (A/B)] × 100

[Equation 2]

Larvae rate (%) = (C/B) × 100

In the formula, A represents the number of insects captured by a lighting device having a low larvae or insect repellent light source substituted for a lighting device having a larval light source. B shows the number of insect catches by the lighting device with the low larvae or the insect repellent light source which did not replace the lighting device with the larval light source. C shows the number of insects captured by a lighting device equipped with a larval light source.

The test results of each Example and the comparative example are put together in the following table|surface and are shown.

As with the above test results, it was confirmed that the larval rate increased as the directivity angle of the UV lamp increased. It is understood that this is due to the fact that the irradiated range of the caterpillar light is widened, thereby attracting more insects. In addition, even when a UV lamp having a directivity angle of 45° is used (Examples 1 and 7), the larger the distance from the low larva or insect repellent light source, the higher the larval rate, but this also increases the distance to be irradiated by the distance. It is understood that because it is wide, it attracts more insects. On the other hand, if you look at the larvae blocking rate, compared to the case of using a UV lamp with a direct angle of 180 °, when UV lamps with direct angles of 45 ° and 120 ° are used, the larval barrier rate is larger, This indicates that it can attract more insects.

2. 2020 Insect Capture Test

In this test, it is assumed that a structure is included in the insect repellent area, and the larvae blocking rate and the larvae rate were investigated for the installation conditions of the dark screen and the larval light source formed assuming the structure. The test conditions in each Example and a comparative example are as follows.

In the table, the “UV lamp with a directional angle of 45°” and “UV lamp with an directional angle of 80°” refer to an ultraviolet emitting LED lamp (straight tube UV-LED, manufactured by Iida Illumination Co., Ltd.) having a maximum peak wavelength of 365 nm, respectively. It is a ramp adjusted to 45° and 80°. In addition, an insect repellent LED lamp (Magic Optron LED, manufactured by Daesung Fine Chemicals) was used as a low larva or insect repellent light source.

In addition, the test procedure of each Example and the comparative example was basically carried out similarly to the test in 2019, and was implemented. When using the lighting device shown in Fig. 17, first, two lighting devices equipped with the low larvae or insect repellent light source described above are arranged at intervals of 10 m in the pavement, and a blackout is provided assuming a structure, A 4.1 m or 8.2 m dark screen was installed immediately after each small caterpillar or insect repellent light source so that each small caterpillar or insect repellent light source was positioned at the midpoint of the width of the black screen. Next, on a straight line between the two lighting devices, at a midpoint spaced 5 m away from each lighting device, a blackout was applied so that light from each lighting device did not leak to the other lighting device side. Next, in Examples 8 to 14, one of the two lighting devices was placed opposite to one another, and a lighting device equipped with each larval light source was placed at a distance of 10 m or 5 m. On the other hand, in Comparative Example 4, the lighting device equipped with the caterpillar light source was installed in the opposite direction to the low caterpillar or insect repellent light source without replacing the light source for the small caterpillars or the insect repellent light source. All of the installed light sources were turned on for about 10 minutes, and insects were captured by an adhesive sheet attached to each lighting device. Thereafter, the lighting device having the larval light source was moved and replaced with another lighting device equipped with a low larva or insect repellent light source (disposition of each lighting device at the time of the first lighting and the lighting at the second lighting) The arrangement of each lighting device is the same as the arrangement shown in FIG. 18). All of 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 in 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 larval inhibition rate and the larval rate were calculated|required by the said Formula 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 caterpillar light is irradiated within the range of the dark film formed assuming a structure is the configuration of Example 9 in which caterpillar light is irradiated other than the range of the dark film or the dark film assuming the structure It is understood that compared with the configuration of Example 10 without formation, the larval arrest rate is slightly higher, and the larval rate is significantly reduced. In addition, in the configuration of Comparative Example 4, in which the larva light source is not replaced with the low larva or insect light source and is directed in the opposite direction to the low larva or insect light source, the larval suppression rate becomes a low value close to the control, and the larval rate is large rose.

Further, the configuration of Example 13 in which the larval light source having an orientation angle of 80° and larval light is irradiated within the approximate range of a blackout having a width of 8.2 m is a larval light source having an orientation angle of 45°, a larval light source having a width of 4.1 m Compared with the configuration of Example 11 in which larval light was irradiated within the approximate range of the blackout, the larval blocking rate was slightly lowered, and the larval rate was slightly increased. It is considered that this is because the irradiation space of the larval light is enlarged as the directivity angle of the larval light source becomes large. On the other hand, in the configuration of Example 13, compared to the configuration of Example 14 having the same configuration as Example 13, except that a dark film assuming a structure was not formed, the larval inhibition rate was about the same, but the larval rate was decreased. It was confirmed that the insect repellent effect could be enhanced by irradiating the caterpillar light toward the structure even when the directing angle of the larval light source was increased.

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