Description

本発明は、植物に、害虫を駆除するための紫外線を照射する害虫駆除用照明装置に関する。   The present invention relates to a lighting device for controlling insects that irradiates plants with ultraviolet rays for controlling insects.

植物に寄生する害虫の駆除方法として、植物に化学農薬を散布する方法が一般的に用いられている。しかしながら、この方法によれば、害虫が化学農薬への耐性を持つようになる虞がある。また、害虫が居る箇所に化学農薬が適切に散布されなかったとき、害虫の駆除が不十分になる。特に、ハダニの場合、ハダニは葉の裏に居ることが多く、このような箇所にまで漏れなく化学農薬を散布するには、散布者に多大な労力を伴う。その他の駆除方法として挙げられる生物農薬は、効果を上げることのできる投入時期及び投入場所を選定することが難しく、また、定期的な投入が必要になるので、コスト高となる。   As a method for controlling pests parasitic on plants, a method of spraying chemical pesticides on plants is generally used. However, according to this method, there is a risk that pests become resistant to chemical pesticides. In addition, when chemical pesticides are not properly sprayed in places where pests are present, pest control is insufficient. In particular, in the case of spider mites, spider mites are often on the back of the leaves, and in order to spray chemical pesticides to such places without omission, it involves a great deal of labor for the sprayer. Biological pesticides listed as other extermination methods are difficult to select the timing and place where they can be effective, and require regular inputs, which increases costs.

そこで、害虫が耐性を持ち難く、且つ低コストで運用可能な駆除策として、害虫を駆除するための紫外線を放出する光源を備えた植物病害駆除用照明装置が知られている。この照明装置においては、光源による紫外線の放射照度が５０μＷ／ｃｍ２以下とされる（例えば、特許文献１を参照）。 Therefore, a plant disease extermination lighting device including a light source that emits ultraviolet rays for exterminating pests is known as an extermination measure that is less resistant to pests and can be operated at low cost. In this illumination device, the irradiance of ultraviolet rays from the light source is 50 μW / cm 2 or less (see, for example, Patent Document 1).

特開２００９−１５３３９７号公報JP 2009-153397 A

ところで、特許文献１に記載のような照明装置により、例えば、ハダニを十分に駆除するためには、２０μＷ／ｃｍ２以上の殺傷能力のある高放射強度の紫外線を連続してハダニに照射する必要がある。しかしながら、強度が２０μｗ／ｃｍ２以上の紫外線をハダニに突然に照射すると、ハダニは驚いて紫外線が照射されていない葉の裏側等に逃げてしまい、ハダニを十分に駆除することができないことがある。また、紫外線の放射強度を更に高めれば、ハダニが逃げる間もなくこれを殺傷できるが、紫外線の放射強度が強すぎると、植物の葉に悪影響を及ぼす虞がある。 By the way, for example, in order to sufficiently remove mites by the illumination device described in Patent Document 1, it is necessary to continuously irradiate mites with high radiation intensity ultraviolet rays having a killing ability of 20 μW / cm 2 or more. There is. However, if the spider mites are suddenly irradiated with ultraviolet rays having an intensity of 20 μw / cm 2 or more, the spider mites may be surprised to escape to the backside of the leaves that are not irradiated with the ultraviolet rays, and the spider mites may not be sufficiently removed. . Further, if the radiation intensity of the ultraviolet rays is further increased, the spider mites can be killed without escaping, but if the radiation intensity of the ultraviolet rays is too strong, there is a possibility of adversely affecting the leaves of the plant.

本発明は、上記課題を解決するためになされたものであり、害虫を効果的に駆除することができる害虫駆除用照明装置を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object thereof is to provide a lighting device for pest control that can effectively control pests.

上記課題を解決するために本発明は、紫外線を含む光を放射する光源と、前記光源を点灯制御する制御部と、を備えた害虫駆除用照明装置において、前記光源は、２６０〜３０５ｎｍの波長を含む紫外線又は２６０〜３０５ｎｍの波長範囲内にピーク波長を有する紫外線を放射し、前記制御部は、前記光源による前記紫外線の放射強度が０．１〜５０μＷ／ｃｍ２の範囲内で、前記害虫の動作を停止させることが可能な停止強度と、前記害虫を殺傷可能な殺傷強度と、を含む少なくとも２種の放射強度を、前記停止強度及び前記殺傷強度の順で段階的に変化させ、且つその変化を繰り返すように前記光源を調光制御することを特徴とする。 In order to solve the above-described problems, the present invention provides a lighting device for pest control comprising a light source that emits light including ultraviolet light, and a control unit that controls lighting of the light source, wherein the light source has a wavelength of 260 to 305 nm. Or ultraviolet light having a peak wavelength within a wavelength range of 260 to 305 nm, and the control unit has a radiation intensity of 0.1 to 50 μW / cm 2 by the light source , Changing at least two kinds of radiation intensities including stop intensity capable of stopping operation and killing intensity capable of killing the pest in order of the stop intensity and the killing intensity, and The light source is dimmed and controlled to repeat the change.

前記制御部は、前記光源による前記紫外線の放射強度が、少なくとも前記害虫の動作を停止させることが可能な停止強度と、前記害虫を殺傷可能な殺傷強度と、を含む複数の設定強度の中で、前記放射強度を段階的に変化させることが好ましい。   The control unit includes a set intensity including a stop intensity at which the radiation intensity of the ultraviolet light from the light source can stop at least the operation of the pest and a kill intensity capable of killing the pest. The radiation intensity is preferably changed stepwise.

前記停止強度は、５〜１５μＷ／ｃｍ２の範囲内にあり、前記殺傷強度は、２０〜５０μＷ／ｃｍ２の範囲内にあることが好ましい。 The stopping strength is preferably in the range of 5 to 15 μW / cm 2 , and the killing strength is preferably in the range of 20 to 50 μW / cm 2 .

前記複数の設定強度は、前記害虫を誘引可能な誘引強度を含むことが好ましい。   The plurality of set strengths preferably include an attractive strength capable of attracting the pests.

前記誘引強度は、０．１〜３μＷ／ｃｍ２の範囲内にあることが好ましい。 The attractive strength is preferably in the range of 0.1 to 3 μW / cm 2 .

前記制御部は、前記光源における前記殺傷強度での前記紫外線の放射期間を３０分以上とすることが好ましい。   It is preferable that the said control part sets the radiation | emission period of the said ultraviolet-ray with the said killing intensity in the said light source as 30 minutes or more.

前記光源は、複数、設けられ、前記制御部は、前記複数の光源における前記紫外線の放射強度の変化態様を互いに同じとすることが好ましい。   It is preferable that a plurality of the light sources are provided, and the control unit has the same change mode of the radiation intensity of the ultraviolet rays in the plurality of light sources.

前記光源は、複数、設けられ、前記制御部は、前記複数の光源の中で、前記紫外線の放射強度を変化させる対象の光源を切り替えることが好ましい。   It is preferable that a plurality of the light sources are provided, and the control unit switches among the plurality of light sources as a target light source for changing a radiation intensity of the ultraviolet rays.

本発明によれば、例えば、低強度での紫外線放射により害虫（例えば、ハダニ）の動作を鈍らせてから高強度で紫外線を放射することにより、害虫を逃がさずにこれに高強度の紫外線を連続して照射させることができ、効果的に害虫を殺傷することができる。また、紫外線の放射強度の変化が繰り返されるので、害虫の殺傷効率を向上させることができる。   According to the present invention, for example, by damaging the action of a pest (e.g. spider mite) by low-intensity ultraviolet radiation and then radiating high-intensity ultraviolet light, the high-intensity ultraviolet light can be applied to the pest without escaping it. Irradiation can be performed continuously, and pests can be effectively killed. Moreover, since the change of the radiation intensity of ultraviolet rays is repeated, the killing efficiency of pests can be improved.

本発明の一実施形態に係る害虫駆除用照明装置（以下、照明装置）について図面を参照して説明する。図１は、本実施形態の照明装置１の構成を示す。照明装置１は、植物Ｐに紫外線を照射するための灯体２と、灯体２を調光制御する調光器３と、を備える。照明装置１は、植物Ｐに寄生する害虫Ｂ１を駆除するため植物Ｐに紫外線を照射するものであり、駆除対象の害虫Ｂ１として、特にハダニ類を想定し、その他、アザミウマ類及びコナジラミ類等の微小昆虫を想定している。ハダニ類には、ナミハダニ、カンザワハダニ、ミカンハダニ等が含まれる。   A pest control lighting device (hereinafter referred to as a lighting device) according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a configuration of a lighting device 1 of the present embodiment. The lighting device 1 includes a lamp body 2 for irradiating the plant P with ultraviolet rays, and a dimmer 3 that performs dimming control on the lamp body 2. The illuminating device 1 irradiates the plant P with ultraviolet rays in order to control the pest B1 parasitic on the plant P. As the pest B1 to be controlled, especially spider mites, and other things such as thrips and whiteflies A small insect is assumed. Spider mites include spider mites, kanzawa spider mites, citrus spider mites, and the like.

灯体２は、紫外線を含む光を放射する光源２１と、光源２１を収容する筐体２２と、筐体２２を支持する支持部材２３とを有する。筐体２２は、光源２１による放射光を外部に出射するための光出射口２２ａを有する。   The lamp body 2 includes a light source 21 that emits light including ultraviolet rays, a housing 22 that houses the light source 21, and a support member 23 that supports the housing 22. The housing 22 has a light exit port 22a for emitting the light emitted from the light source 21 to the outside.

光源２１は、略２６０〜３０５ｎｍの波長を含む紫外線又は２６０〜３０５ｎｍの波長範囲内にピーク波長を有する紫外線を放射する。光源２１は、蛍光灯、メタルハライドランプ、キセノンランプ、又は紫外線ＬＥＤ等により構成できる。   The light source 21 emits ultraviolet light including a wavelength of approximately 260 to 305 nm or ultraviolet light having a peak wavelength within a wavelength range of 260 to 305 nm. The light source 21 can be composed of a fluorescent lamp, a metal halide lamp, a xenon lamp, an ultraviolet LED, or the like.

光源２１は、図２に示されるように、放射光における上記波長範囲内の成分割合が例えば９割以上であって、上記波長範囲外の成分が殆ど無いものにより構成される。光源２１は、図３に示されるように、少なくとも上記波長範囲内の波長成分の光を放射するものであり、その放射光には上記波長範囲外の波長成分が含まれていてもよい。この場合、光出射口２２ａには、上記波長範囲内の紫外線を透過し上記波長範囲外の光をカットする波長制御用の光学フィルタが設けられる。この光学フィルタは、例えば、石英ガラス又はフッ素樹脂等の紫外線を透過可能な基材と、その基材上に形成された上記波長範囲外の光をカットするための光学多層膜とにより構成される。なお、以下の説明では、図２に示したような略２６０〜３０５ｎｍの波長を含む紫外線又は２６０〜３０５ｎｍの波長範囲内にピーク波長を有する紫外線を、単に紫外線という。   As shown in FIG. 2, the light source 21 is configured by a component ratio of the emitted light within the wavelength range of, for example, 90% or more and almost no component outside the wavelength range. As shown in FIG. 3, the light source 21 emits light having a wavelength component within at least the above wavelength range, and the emitted light may include a wavelength component outside the above wavelength range. In this case, the light emission port 22a is provided with an optical filter for wavelength control that transmits ultraviolet rays within the wavelength range and cuts light outside the wavelength range. This optical filter includes, for example, a base material that can transmit ultraviolet rays such as quartz glass or fluororesin, and an optical multilayer film that is formed on the base material and cuts light outside the above wavelength range. . In the following description, ultraviolet rays having a wavelength of approximately 260 to 305 nm as shown in FIG. 2 or ultraviolet rays having a peak wavelength in the wavelength range of 260 to 305 nm are simply referred to as ultraviolet rays.

光源２１による紫外線の放射は、害虫Ｂ１が卵、幼虫、さなぎ、成虫のいずれの成長段階であっても実施することが望ましいが、いずれかの成長段階のときだけ実施してもよい。また、害虫Ｂ１がハダニである場合、ハダニは草花、野菜、ラン類、花木、庭木及び果樹等、殆どの植物に寄生するので、光源２１は、植物の種類を問わず、いずれの植物に対しても使用できる。   Although it is desirable that the ultraviolet light emitted from the light source 21 is in any growth stage of the insect pest B1 such as egg, larva, pupa, and adult, it may be executed only in any growth stage. In addition, when the pest B1 is a spider mite, the spider mite parasitizes most plants such as flowers, vegetables, orchids, flower trees, garden trees and fruit trees, so the light source 21 can be used for any plant regardless of the type of plant. Can also be used.

筐体２２には、板状又はシート状の反射部材が収納されていることが望ましい。この反射部材は、光源２１による放射光のうち、光出射口２２ａとは反対側に進む光を光出射口２２ａに向けて反射するように構成され、その材質は例えばアルミとされる。支持部材２３は、筐体２２の光出射口２２ａからの光出射方向を変更可能とするため、筐体２２を上下又は左右に首振り自在に支持していることが望ましい。また、支持部材２３は、植物Ｐの成長に応じて灯体２の高さを変更できるように伸縮自在に構成されていてもよい。   It is desirable that the casing 22 accommodates a plate-like or sheet-like reflecting member. The reflecting member is configured to reflect the light emitted from the light source 21 that travels to the side opposite to the light exit port 22a toward the light exit port 22a, and is made of, for example, aluminum. The support member 23 desirably supports the housing 22 so as to be swingable up and down or left and right so that the direction of light emission from the light exit port 22a of the housing 22 can be changed. Further, the support member 23 may be configured to be stretchable so that the height of the lamp body 2 can be changed according to the growth of the plant P.

調光器３は、タイマ３１と、タイマ３１による計時結果に基づいて光源２１を点灯制御する制御回路３２（制御部）とを有する。制御回路３２は、光源２１による紫外線の放射強度が０．１〜５０μＷ／ｃｍ２の範囲内で時間的に変化し、且つその変化を繰り返し、その変化が１日のうちで複数回生じるように光源２１を調光制御する。この調光制御処理において、制御回路３２は、光源２１による紫外線の放射強度が、少なくとも、後述の停止強度及び殺傷強度を含む複数の設定強度の中で、上記放射強度を段階的に変化させる。上記複数の設定強度には、害虫Ｂ１を誘引可能な誘引強度が含まれることが望ましい。そのような場合、制御回路３２は、光源２１による紫外線の放射強度を、誘引強度、停止強度、殺傷強度の順に変化させる。 The dimmer 3 includes a timer 31 and a control circuit 32 (control unit) that controls the lighting of the light source 21 based on the time measured by the timer 31. The control circuit 32 causes the ultraviolet radiation intensity from the light source 21 to change over time within a range of 0.1 to 50 μW / cm 2 and repeats the change, so that the change occurs a plurality of times in one day. The light source 21 is dimmed and controlled. In this dimming control process, the control circuit 32 changes the radiation intensity stepwise in a plurality of set intensities, including at least the later-described stop intensity and killing intensity, of the ultraviolet radiation intensity from the light source 21. The plurality of set intensities preferably include an attraction intensity that can attract the pest B1. In such a case, the control circuit 32 changes the radiation intensity of the ultraviolet rays from the light source 21 in the order of attraction intensity, stop intensity, and killing intensity.

誘引強度は、害虫Ｂ１を誘引可能な強度であり、例えば、略０．１〜３μＷ／ｃｍ２の範囲内にある。誘引強度の下限値は、０でなければよく、ここで略０．１μＷ／ｃｍ２以上としているのは、それ以下の調光制御が現実的でないことに基づく。誘引強度での紫外線の放射期間は、例えば、略１５〜３０分であり、誘虫のために０．０９〜５．４ｍＪの紫外線が放射される。停止強度は、害虫Ｂ１の動作を鈍らせて停止させることが可能な強度であり、例えば、略５〜１５μＷ／ｃｍ２の範囲内にある。停止強度での紫外線の放射期間は、例えば、略１０〜１５分であり、害虫Ｂ１の動きを停止させるために３．６〜１３．５ｍＪの紫外線が照射される。殺傷強度は、害虫Ｂ１を弱らせたり、物理的なダメージを与えたりして、害虫Ｂ１を殺傷可能な強度であり、例えば、略２０〜５０μＷ／ｃｍ２の範囲内にある。殺傷強度での紫外線の放射期間は、例えば、略３０分以上であり、殺虫のために３６ｍＪ以上の紫外線が放射される。誘引強度、停止強度及び殺傷強度での紫外線放射による効果については、ハダニを対象とした実験により確認済みである。 The attracting strength is a strength capable of attracting the pest B1 and is, for example, in a range of about 0.1 to 3 μW / cm 2 . The lower limit value of the attractive strength may not be 0, and the reason why the lower limit of about 0.1 μW / cm 2 is set here is that dimming control below that is not practical. The radiation period of the ultraviolet rays with the attractive intensity is, for example, approximately 15 to 30 minutes, and 0.09 to 5.4 mJ of ultraviolet rays are emitted for the attracting insects. The stop strength is a strength at which the operation of the pest B1 can be dulled and stopped, and is, for example, in a range of approximately 5 to 15 μW / cm 2 . The radiation period of ultraviolet rays at the stop intensity is, for example, about 10 to 15 minutes, and 3.6 to 13.5 mJ of ultraviolet rays are irradiated to stop the movement of the pest B1. The killing strength is a strength capable of killing the pest B1 by weakening the pest B1 or causing physical damage, and is, for example, in a range of about 20 to 50 μW / cm 2 . The ultraviolet radiation period at the killing intensity is, for example, approximately 30 minutes or more, and ultraviolet radiation of 36 mJ or more is emitted for insecticidal use. The effects of ultraviolet radiation on attracting strength, stopping strength and killing strength have been confirmed by experiments on spider mites.

次に、制御回路３２が後述するパターンに基づいて光源２１をそれぞれ調光制御したときの、害虫駆除効果を調べるために実施される実験について説明する。   Next, an experiment will be described that is carried out in order to examine the pest control effect when the control circuit 32 performs dimming control of the light source 21 based on a pattern to be described later.

図４に示すように、この実験では、植物Ｐとして胡瓜を１株用意し、その胡瓜を略１ｍ×１ｍ×１．５ｍの寸法の透明容器５０に入れて栽培し、栽培開始後、５〜７日目に害虫Ｂ１のハダニを５頭、胡瓜の下部の１葉に接種した。そして、光源２１による放射光が胡瓜の下方から照射されるように光源２１を配置した上で、ハダニを接種した日から３日後に光源２１を点灯させた。また、光源２１による紫外線の放射強度（以下、単に紫外線の放射強度という）を、以下に説明する第１〜第３変化パターンと第１〜第３比較パターンとでそれぞれ変化させた。このような実験の結果については、透明容器５０に入れた胡瓜とその胡瓜に紫外線を照射する照明装置１との組み合わせを３組用意し、これら３組の平均値で評価した。その評価項目は、栽培から１．５ヶ月後に拡大鏡を用いて目視で数えた、任意の２葉の表と裏に居るハダニの頭数である。   As shown in FIG. 4, in this experiment, one strain of pepper was prepared as the plant P, and the pepper was cultivated in a transparent container 50 having a size of about 1 m × 1 m × 1.5 m. On day 7, 5 spider mites of pest B1 were inoculated into one leaf at the bottom of pepper. And after arranging the light source 21 so that the emitted light by the light source 21 was irradiated from the bottom of pepper, the light source 21 was turned on 3 days after the day which inoculated the spider mite. In addition, the ultraviolet radiation intensity (hereinafter simply referred to as ultraviolet radiation intensity) from the light source 21 was changed between first to third change patterns and first to third comparison patterns described below. About the result of such an experiment, three sets of the combination of the pepper put in the transparent container 50 and the illuminating device 1 which irradiates ultraviolet rays to the pepper were prepared, and the average value of these three sets was evaluated. The evaluation item is the number of spider mites on the front and back of any two leaves, counted visually with a magnifying glass 1.5 months after cultivation.

以下、調光器３による光源２１の変化パターン（第１〜第３変化パターン）について詳述する。ここで、上述した誘引強度、停止強度及び殺傷強度を、それぞれｐ１、ｐ２、ｐ３とする。   Hereinafter, the change pattern (first to third change patterns) of the light source 21 by the dimmer 3 will be described in detail. Here, the above-described attracting strength, stopping strength, and killing strength are defined as p1, p2, and p3, respectively.

図５は、第１変化パターンを示し、図６は、第１変化パターンに基づく調光制御処理の手順を示す。制御回路３２は、タイマ３１によるカウント値をリセットし（図６のＳ１１）、タイマ３１による計時を開始する（Ｓ１２）。そのとき、制御回路３２は、紫外線の最小放射強度ｐ０を０．１μＷ／ｃｍ２とし（Ｓ１３）、タイマ３１による計時開始からの経過時間（以下、計時時間という）が第１期間ｔ１以内である間（Ｓ１４でＮｏ）、それを維持する。第１期間ｔ１は略１５分である。計時時間が第１期間ｔ１を過ぎると（Ｓ１４でＹｅｓ）、制御回路３２は、紫外線の放射強度を停止強度ｐ２に切り替える（Ｓ１５）。計時時間が第１期間ｔ１と第２期間ｔ２との合計期間以内である間、すなわち停止強度ｐ２への切替え後からの経過時間が第２期間ｔ２以内である間（Ｓ１６でＮｏ）、制御回路３２は、停止強度ｐ２を維持する。第２期間ｔ２は略１５分である。計時時間が上記合計期間を過ぎると（Ｓ１６でＹｅｓ）、制御回路３２は、紫外線の放射強度を殺傷強度ｐ３に切り替える（Ｓ１７）。その後、計時時間が第１期間ｔ１、第２期間ｔ２及び第３期間ｔ３の合計期間以内である間、すなわち殺傷強度ｐ３への切替え後からの経過時間が第３期間ｔ３以内である間（Ｓ１８でＮｏ）、制御回路３２は、殺傷強度ｐ３を維持する。計時時間が上記合計期間を過ぎると（Ｓ１８でＹｅｓ）、Ｓ１１の処理に戻る。第３期間は略３０分である。 FIG. 5 shows a first change pattern, and FIG. 6 shows a procedure of dimming control processing based on the first change pattern. The control circuit 32 resets the count value by the timer 31 (S11 in FIG. 6), and starts the time measurement by the timer 31 (S12). At that time, the control circuit 32 sets the minimum radiation intensity p0 of the ultraviolet ray to 0.1 μW / cm 2 (S13), and the elapsed time from the start of the time measurement by the timer 31 (hereinafter referred to as time measurement time) is within the first period t1. It is maintained for a while (No in S14). The first period t1 is approximately 15 minutes. When the time measured exceeds the first period t1 (Yes in S14), the control circuit 32 switches the ultraviolet radiation intensity to the stop intensity p2 (S15). While the measured time is within the total period of the first period t1 and the second period t2, that is, while the elapsed time after switching to the stop strength p2 is within the second period t2 (No in S16), the control circuit 32 maintains the stop strength p2. The second period t2 is approximately 15 minutes. When the time measured exceeds the total period (Yes in S16), the control circuit 32 switches the ultraviolet radiation intensity to the killing intensity p3 (S17). After that, while the measured time is within the total period of the first period t1, the second period t2, and the third period t3, that is, while the elapsed time after switching to the killing strength p3 is within the third period t3 (S18). No), the control circuit 32 maintains the killing strength p3. When the measured time exceeds the total period (Yes in S18), the process returns to S11. The third period is approximately 30 minutes.

図７は、第２変化パターンを示し、図８は、第２変化パターンに基づく調光制御処理の手順を示す。この調光制御処理は、上記第１変化パターンに基づく調光制御処理（図６を参照）において、Ｓ１３の処理を、紫外線の放射強度を誘引強度ｐ１とするＳ２１の処理（図８を参照）に変更したものである。   FIG. 7 shows a second change pattern, and FIG. 8 shows a procedure of dimming control processing based on the second change pattern. In the dimming control process, in the dimming control process based on the first change pattern (see FIG. 6), the process of S13 is performed as the process of S21 in which the radiation intensity of ultraviolet rays is the induced intensity p1 (see FIG. 8). It has been changed to.

図９は、第３変化パターンを示し、図１０は、第３変化パターンに基づく調光制御処理の手順を示す。この調光制御処理は、上記第１変化パターンに基づく調光制御処理（図６を参照）において、Ｓ１３〜Ｓ１８の処理をＳ３１〜Ｓ３４の処理（図１０を参照）に変更したものである。上記変更により、紫外線の放射強度を０とする第１期間ｔ１が省略され、その代わりに、紫外線の放射強度を殺傷強度ｐ３とする第３期間ｔ３が延長されてｔ３’≒４５分に変更される。   FIG. 9 shows a third change pattern, and FIG. 10 shows a procedure of dimming control processing based on the third change pattern. This dimming control process is obtained by changing the processes of S13 to S18 to the processes of S31 to S34 (see FIG. 10) in the dimming control process based on the first change pattern (see FIG. 6). With the above change, the first period t1 in which the ultraviolet radiation intensity is 0 is omitted, and instead, the third period t3 in which the ultraviolet radiation intensity is the killing intensity p3 is extended and changed to t3′≈45 minutes. The

Ｓ１２の処理後、制御回路３２は、紫外線の放射強度を停止強度ｐ２とし（Ｓ３１）、計時時間が第２期間ｔ２以内である間（Ｓ３２でＮｏ）、停止強度ｐ２を維持する。計時時間が第２期間ｔ２を過ぎると（Ｓ３２でＹｅｓ）、制御回路３２は、紫外線の放射強度を殺傷強度ｐ３に切り替える（Ｓ３３）。計時時間が第２期間ｔ２と第３期間ｔ３’との合計期間以内である間、すなわち殺傷強度ｐ３への切替え後からの経過時間が第３期間ｔ３’以内である間（Ｓ３４でＮｏ）、制御回路３２は、殺傷強度ｐ３を維持する。第３期間ｔ３’は略４５分である。計時時間が上記合計期間を過ぎると（Ｓ３４でＹｅｓ）、Ｓ１１の処理に戻る。   After the process of S12, the control circuit 32 sets the radiation intensity of the ultraviolet rays to the stop intensity p2 (S31), and maintains the stop intensity p2 while the measured time is within the second period t2 (No in S32). When the measured time has passed the second period t2 (Yes in S32), the control circuit 32 switches the ultraviolet radiation intensity to the killing intensity p3 (S33). While the measured time is within the total period of the second period t2 and the third period t3 ′, that is, while the elapsed time after switching to the killing strength p3 is within the third period t3 ′ (No in S34), The control circuit 32 maintains the killing strength p3. The third period t3 'is approximately 45 minutes. When the measured time exceeds the total period (Yes in S34), the process returns to S11.

次に、上記第１〜第３変化パターンと対比される第１〜第３比較パターンについて詳述する。図１１は、第１比較パターンを示す。本比較パターンでは、紫外線の放射強度が常に０とされ、紫外線が放射されない。図１２は、第２比較パターンを示す。本比較パターンは、上記第３変化パターン（図９を参照）において、紫外線の放射強度を停止強度ｐ２とする処理を、その放射強度を０とする処理に変更したものである。図１３は、第３比較パターンを示す。本比較パターンでは、紫外線の放射強度が常に殺傷強度ｐ３とされ、殺傷強度ｐ３の紫外線が連続的に放射される。   Next, the first to third comparison patterns compared with the first to third change patterns will be described in detail. FIG. 11 shows a first comparison pattern. In this comparative pattern, the ultraviolet radiation intensity is always 0, and no ultraviolet radiation is emitted. FIG. 12 shows a second comparison pattern. This comparison pattern is obtained by changing the process of setting the radiation intensity of ultraviolet rays to the stop intensity p2 in the third change pattern (see FIG. 9) to the process of setting the radiation intensity to 0. FIG. 13 shows a third comparison pattern. In this comparison pattern, the ultraviolet radiation intensity is always set to the killing intensity p3, and the ultraviolet radiation having the killing intensity p3 is continuously emitted.

第１変化パターン〜第３変化パターンと第１比較パターン〜第３比較パターンとによる害虫駆除効果の評価結果を下記表１に示す。なお、上述したように、各パターンにおいて、実験開始時に夫々５頭のハダニが接種された。

Figure 0006153109
Table 1 below shows the evaluation results of the pest control effect by the first change pattern to the third change pattern and the first comparison pattern to the third comparison pattern. As described above, in each pattern, 5 spider mites were inoculated at the start of the experiment.
Figure 0006153109

上記表１に示されるように、ハダニは繁殖力が非常に強く、第１比較パターンのように紫外線が照射されなければ、ハダニは１．５ヶ月で数十倍にまで増殖する。このような繁殖力に起因して、第１変化パターン〜第３変化パターン、第２比較パターン及び第３比較パターンのように紫外線が放射された場合であっても、ハダニの頭数が接種時よりも増える。しかしながら、第１変化パターン〜第３変化パターンでは、第２比較パターン及び第３比較パターンと比べて、ハダニの頭数が１／４以下に抑えられる。その理由を次に説明する。   As shown in Table 1 above, spider mites have a very strong fertility, and unless they are irradiated with ultraviolet rays as in the first comparative pattern, spider mites grow to tens of times in 1.5 months. Due to such fertility, even when ultraviolet rays are radiated as in the first change pattern to the third change pattern, the second comparison pattern, and the third comparison pattern, the number of spider mites is greater than that at the time of inoculation. Will also increase. However, in the first change pattern to the third change pattern, the number of spider mites is suppressed to ¼ or less compared to the second comparison pattern and the third comparison pattern. The reason will be described next.

第１変化パターン〜第３変化パターン、第２比較パターン及び第３比較パターンでは、ハダニの頭数は、紫外線が照射され易い葉の裏側よりも、紫外線が照射され難い表側の方が多くなっており、ハダニが葉の裏側から葉の表側に移動することがわかる。ハダニの移動速度は、基本的に遅いことから、胡瓜のように葉が大きい植物では、葉の裏側から表側に回るために２０分以上の時間を要する。そこで、余裕を持たせて例えば３０分間以上、殺傷強度ｐ３で紫外線を照射すればハダニを殺虫できると見込まれる。しかしながら、第３比較パターンの結果に示されるように、紫外線を連続照射しただけでは、十分な殺虫効果が得られないことが分かった。これは、ハダニが強力な紫外線に驚き、急いで逃げたためであると推測される。一方、殺傷強度ｐ３での紫外線放射を第２比較パターンのように断続的にすると、殺虫効果は僅かに向上するものの、その程度は限定的である。   In the 1st change pattern-the 3rd change pattern, the 2nd comparison pattern, and the 3rd comparison pattern, the number of spider mites is larger on the front side that is hard to be irradiated with ultraviolet rays than the back side of the leaves that are easily irradiated with ultraviolet rays. It can be seen that spider mites move from the back side of the leaf to the front side of the leaf. Spider mite movement speed is basically slow, so in plants with large leaves such as pepper, it takes 20 minutes or more to turn from the back side of the leaf to the front side. Therefore, it is expected that spider mites can be killed by irradiating with ultraviolet rays with a killing strength p3 for 30 minutes or more with a margin. However, as shown in the results of the third comparative pattern, it was found that sufficient insecticidal effect cannot be obtained only by continuously irradiating with ultraviolet rays. This is presumably because spider mites were surprised by the powerful ultraviolet rays and ran away in a hurry. On the other hand, when the ultraviolet radiation at the killing intensity p3 is intermittently as in the second comparative pattern, the insecticidal effect is slightly improved, but the degree is limited.

一方、第１変化パターン〜第３変化パターンではいずれも、上述した通り、ハダニの頭数が激減している。第１変化パターン〜第３変化パターンの共通点は、特に第２比較パターンと比べて、殺傷強度ｐ３で紫外線を放射する前に、停止強度ｐ２で紫外線を放射した点である。すなわち、停止強度ｐ２での紫外線放射によりハダニの動きを鈍らせ、その状態で殺傷強度ｐ３の紫外線を放射したことで、ハダニを逃がさずにハダニに殺傷強度ｐ３の紫外線を多量に浴びせることができ、殺虫効果を飛躍的に向上させることができた。   On the other hand, in all of the first change pattern to the third change pattern, the number of spider mites is drastically reduced as described above. The common point of the first change pattern to the third change pattern is that, compared with the second comparison pattern, the ultraviolet ray is emitted with the stop intensity p2 before the ultraviolet ray is emitted with the killing intensity p3. That is, the movement of the spider mite is slowed down by the ultraviolet radiation with the stop intensity p2, and the spider mite is irradiated with the ultraviolet light with the kill intensity p3 without letting the spider mite escape by radiating the ultraviolet light with the kill intensity p3 in that state. The insecticidal effect could be improved dramatically.

本実施形態では、特に害虫Ｂ１がハダニである場合、低強度での紫外線放射により害虫Ｂ１の動作を鈍らせてから高強度で紫外線を放射することにより、害虫Ｂ１を逃がさずに、害虫Ｂ１に高強度の紫外線を連続して照射させることができ、害虫Ｂ１を殺傷できる。従って、害虫Ｂ１が成虫であれば害虫Ｂ１の産卵を防ぐことで増殖を抑制することができ、たとえ産卵がなされても高強度の紫外線放射により孵化を防ぐことで害虫Ｂ１の発生を抑制することができ、そのため、害虫Ｂ１を確実に防除することができる。しかも、紫外線の放射強度の変化が繰り返されることで、害虫防除効果の確実性を高くすることができる。また、光源２１による紫外線の放射強度は、予め設定された複数の設定強度の中で段階的に切り替えるだけでよいので、放射強度を変化させるための構成は簡単なもので済む。   In this embodiment, in particular, when the pest B1 is a spider mite, the pest B1 is radiated with high intensity by slowing down the operation of the pest B1 by irradiating the low-intensity ultraviolet radiation, and without causing the pest B1 to escape. High-intensity ultraviolet rays can be continuously irradiated, and the pest B1 can be killed. Therefore, if the insect pest B1 is an adult, the growth can be suppressed by preventing the egg laying of the insect pest B1, and even if the egg is laid, the generation of the insect pest B1 is suppressed by preventing the hatching by high-intensity ultraviolet radiation. Therefore, the pest B1 can be reliably controlled. Moreover, the reliability of the pest control effect can be increased by repeating the change in the radiation intensity of the ultraviolet rays. In addition, since the ultraviolet radiation intensity from the light source 21 only needs to be switched in stages among a plurality of preset intensity settings, the configuration for changing the radiation intensity is simple.

また、第１、第２変化パターンの場合、第３変化パターンと比べて、誘引強度ｐ０，ｐ１による紫外線の放射期間が追加されるので、紫外線から逃げていた害虫Ｂ１が紫外線の照射領域に戻る可能性が出て来る。そのような場合、それらの害虫Ｂ１に停止強度ｐ２及び殺傷強度ｐ３で紫外線を浴びせることができ、従って、害虫Ｂ１の防除効果が向上する。また、紫外線放射の休止、害虫Ｂ１の動作停止及び殺傷という一連の流れにより、害虫Ｂ１の防除をより効果的に実施することができる。   Further, in the case of the first and second change patterns, an ultraviolet radiation period with the attractive intensities p0 and p1 is added as compared with the third change pattern, so that the pest B1 that has escaped from the ultraviolet light returns to the ultraviolet irradiation region. The possibility comes out. In such a case, those pests B1 can be exposed to ultraviolet rays with a stopping strength p2 and a killing strength p3, and thus the control effect of the pest B1 is improved. Further, the pest B1 can be more effectively controlled by a series of flows of ultraviolet radiation pause, pest B1 operation stop, and killing.

また、殺傷強度ｐ３での紫外線の放射期間が３０分以上とされる。従って、害虫Ｂ１がハダニである場合、ハダニが例えば紫外線の当たり難い葉の裏側から紫外線の当たり易い葉の表側に逃げようと移動しても、その移動期間中に殺傷強度ｐ３の紫外線を継続してハダニに照射し続けることができる。そのため、ハダニを確実に殺傷し駆除することができる。   Further, the ultraviolet radiation period at the killing strength p3 is set to 30 minutes or more. Therefore, when the pest B1 is a spider mite, even if the spider mite moves to escape from the back side of the leaf that is difficult to hit with ultraviolet rays to the front side of the leaf that is easily hit with ultraviolet rays, the ultraviolet ray with the killing strength p3 is continued during the moving period. Can continue to irradiate spider mites. Therefore, spider mites can be surely killed and exterminated.

次に、上記実施形態の変形例について図面を参照して説明する。以下の変形例において、上記実施形態と同一の構成が複数ある場合、それらを区別するため、上記実施形態の符号の末尾に個別のアルファベットを付加したものを用いる。   Next, a modification of the above embodiment will be described with reference to the drawings. In the following modified examples, when there are a plurality of configurations identical to those in the above embodiment, in order to distinguish them, those obtained by adding individual alphabets to the end of the reference numerals in the above embodiment are used.

図１４は、上記実施形態の一変形例に係る照明装置１の構成を示す。本変形例の照明装置１は、複数の灯体（図例では２つの灯体２Ａ、２Ｂ）を備える。灯体２Ａは、光源２１Ａ、筺体２２Ａ及び支持部材２３Ａを有し、灯体２Ｂは、光源２１Ｂ、筺体２２Ｂ及び支持部材２３Ｂを有する。本変形例の照明装置１における光源の数は、上記に限定されない。   FIG. 14 shows a configuration of the illumination device 1 according to a modification of the embodiment. The lighting device 1 of the present modification includes a plurality of lamps (two lamps 2A, 2B in the illustrated example). The lamp body 2A includes a light source 21A, a housing 22A, and a support member 23A, and the lamp body 2B includes a light source 21B, a housing 22B, and a support member 23B. The number of light sources in the illumination device 1 of the present modification is not limited to the above.

光源２１Ａ、２１Ｂは、植物Ｐの葉の表側と裏側の両方に紫外線を照射するため、植物Ｐの上方と下方にそれぞれ配置されている。この配置のため、支持部材２３Ａ、２３Ｂは、予め長さが相違するように構成されるか、又は伸縮自在な構成とされ、使用時に伸び縮みさせることにより、長さに差が設けられる。制御回路３２は、光源２１Ａ、２１Ｂにおける紫外線の放射強度の変化態様を互いに略同じとする。すなわち、制御回路３２は、光源２１Ａ、２１Ｂによる紫外線の放射強度を、略同じタイミングで、略同じ値に変化させる。   The light sources 21 </ b> A and 21 </ b> B are arranged above and below the plant P in order to irradiate both the front side and the back side of the leaves of the plant P with ultraviolet rays. Because of this arrangement, the support members 23A and 23B are configured to have different lengths in advance or are configured to be extendable and contracted, and a difference in length is provided by extending and contracting during use. The control circuit 32 makes the change modes of the ultraviolet radiation intensity in the light sources 21A and 21B substantially the same. That is, the control circuit 32 changes the radiation intensity of the ultraviolet rays from the light sources 21A and 21B to substantially the same value at substantially the same timing.

上記実施形態のように、紫外線を一方向から照射した場合、葉の裏側だけでなく、複数の葉が重なり合ったときに光源の奥方にある葉の表面側にも陰ができ、この陰が害虫Ｂ１の隠れ場所となることがある。これに対して、本変形例によれば、上述した陰ができ難いので、害虫Ｂ１の隠れ場所を少なくし、より効果的に害虫Ｂ１を殺傷することができる。また、植物Ｐの葉の表側と裏側の両方に紫外線を略同時に略同じ強度で照射することができ、特に殺傷強度ｐ３での紫外線放射期間には、害虫Ｂ１の逃げ場をより確実になくして、害虫Ｂ１の防除効果を向上させることができる。   When the ultraviolet rays are irradiated from one direction as in the above embodiment, not only the back side of the leaf but also the surface side of the leaf in the back of the light source when a plurality of leaves overlap, the shade is a pest. It may be a hidden place for B1. On the other hand, according to this modification, since the above-described shade is difficult to be formed, the hiding place of the pest B1 can be reduced, and the pest B1 can be killed more effectively. Moreover, both the front side and the back side of the leaves of the plant P can be irradiated with ultraviolet rays at substantially the same intensity at the same time, and in particular during the ultraviolet radiation period at the killing intensity p3, the escape place of the pest B1 is more reliably eliminated, The control effect of the pest B1 can be improved.

図１５は、上記実施形態の他の変形例に係る照明装置１の構成を示す。本変形例の照明装置は、複数用いられて、照明システムを構成する。図例では、２台の照明装置１Ａ、１Ｂを示すが、照明装置１の数は、これに限定されず、複数であればよい。照明装置１Ａは、灯体２Ａ（光源２１Ａ、筺体２２Ａ、支持部材２３Ａ）及び調光器３Ａを有し、照明装置１Ｂは、灯体２Ｂ（光源２１Ｂ、筺体２２Ｂ、支持部材２３Ｂ）及び調光器３Ｂを有する。   FIG. 15 shows a configuration of a lighting device 1 according to another modification of the embodiment. A plurality of lighting devices according to the present modification are used to constitute a lighting system. In the example of the figure, two lighting devices 1A and 1B are shown, but the number of lighting devices 1 is not limited to this and may be plural. The lighting device 1A includes a lamp body 2A (light source 21A, housing 22A, support member 23A) and a dimmer 3A, and the lighting device 1B includes a lamp body 2B (light source 21B, housing 22B, support member 23B) and light control. A container 3B.

光源２１Ａ、２１Ｂを用いた駆除方法として、又は光源２１Ａ、２１Ｂのうち、紫外線の放射強度を変化させる対象、すなわち調光制御対象の光源が切り替えられる。この切替え制御が行われる場合、調光制御対象とされる光源だけが点灯し、その他の光源は消灯する。本例においても、上記変形例と同等の効果が得られる。   As an extermination method using the light sources 21A and 21B, or among the light sources 21A and 21B, a target for changing the radiation intensity of ultraviolet rays, that is, a light source to be dimming controlled is switched. When this switching control is performed, only the light source to be dimmed is turned on and the other light sources are turned off. Also in this example, the same effect as the above modification can be obtained.

上述した図１４に示した葉の表側と裏側の両方に紫外線を照射する変形例（上下から同時照射）、及び図１５に示した調光制御対象の光源が切り替えられる変形例（切替照明）による害虫防除の評価結果を下記表２に示す。ここでも、各パターンにおいて、実験開始時に夫々５頭のハダニが接種された。また、これらの変形例における紫外線放射強度は、図７に示した第２変化パターンに準じ、また、切り替え照射の照射パターンは、図７におけるｔ１＋ｔ２の期間で殺傷期間を、ｔ３の期間で誘引・停止期間を設けた。なお、表２では、下方から紫外線を照射した実施例（図４参照）の結果（表１で示した第２変化パターンと同サンプル）を参考のために載せている。   According to the above-described modified example (simultaneous irradiation from above and below) that irradiates both the front side and the back side of the leaf shown in FIG. 14 and the modified example (switching illumination) in which the light source of the dimming control target shown in FIG. The evaluation results of pest control are shown in Table 2 below. Again, each pattern was inoculated with 5 spider mites at the start of the experiment. In addition, the ultraviolet radiation intensity in these modified examples conforms to the second change pattern shown in FIG. 7, and the irradiation pattern of switching irradiation induces a killing period in the period of t1 + t2 in FIG. A suspension period was established. In Table 2, the results of the example (see FIG. 4) irradiated with ultraviolet rays from below (the same sample as the second change pattern shown in Table 1) are listed for reference.

Figure 0006153109
Figure 0006153109

上記表２に示されるように、上下から同時照射、及び切替照明では、葉の裏側だけでなく、表側にも紫外線が照射されるので、下方から葉の裏側を中心に紫外線を照射して実施例に比べて、害虫予防効果を高くすることができる。特に、切替照明は、下方からの照射と電力消費量が同じであり、同時照射の半分とすることができ、しかもそれらを上回る害虫予防効果を得ることができた。   As shown in Table 2 above, in simultaneous illumination from the top and bottom and switching illumination, not only the back side of the leaves but also the front side is irradiated with ultraviolet rays. Compared to examples, the pest prevention effect can be increased. In particular, the switching illumination has the same power consumption as the irradiation from below, and can be reduced to half of the simultaneous irradiation, and moreover, it is possible to obtain a pest-preventing effect that exceeds those.

なお、本発明は、上記実施形態及び変形例の構成に限定されるものでなく、使用目的に応じ、様々な変形が可能である。例えば、制御回路３２は、光源２１による紫外線の放射強度の変化について、第１変化パターン乃至第３変化パターンのうちのいずれかとその他のものと組み合わせ、その組合せを繰り返してもよい。   In addition, this invention is not limited to the structure of the said embodiment and modification, A various deformation | transformation is possible according to a use purpose. For example, the control circuit 32 may combine any one of the first change pattern to the third change pattern with respect to the change in the radiation intensity of the ultraviolet rays by the light source 21 and repeat the combination.

また、上記変形例において、制御回路３２は、光源２１Ａ、２１Ｂの中で、紫外線の放射強度を変化させる対象の光源、すなわち調光制御対象の光源を切り替えてもよい。その場合、制御回路３２は、調光制御対象の光源だけを点灯し、その他の光源を消灯する。このような切替え制御によれば、消費電力を削減しつつ、害虫Ｂ１の防除効果の向上を図ることができる。   Moreover, in the said modification, the control circuit 32 may switch the light source of the object which changes the radiation intensity of an ultraviolet-ray among the light sources 21A and 21B, ie, the light source of light control object. In that case, the control circuit 32 turns on only the light source subject to dimming control, and turns off the other light sources. According to such switching control, it is possible to improve the control effect of the pest B1 while reducing power consumption.
