Description

【0001】
【発明の属する分野】
本発明は、紫外線を面発光させて虫を誘引し、発光面上の粘着捕虫シートに虫を付着させる捕虫器に関するものである。
【0002】
【従来の技術及び発明が解決しようとする課題】
従来から、紫外線で虫を誘引し、紫外線の前方に配備した金網に電流を流して、金網に接した虫を感電死させる電撃捕虫器が実用されている。
上記電撃捕虫器は、電流が通じている金網が露出しているため、危険であった。
本発明は、上記問題を解決できる捕虫器を明らかにするものである。
【0003】
【課題を解決する手段】
本発明は紫外線で虫を誘引し、粘着剤層を有するシートで虫を捕獲する光誘引粘着捕虫器であって、透明導光板 (11) の端面に対向して紫外線ランプ (12) が配備され該導光板の前面から斑なく紫外線を面発光する紫外線面発光装置(1)と、該紫外線面発光装置(1)の発光面の前側に交換可能に配備され表面に粘着剤層(81)を有する紫外線透過性捕虫シート(8)とからなる。
【0004】
紫外線捕虫器の前方に、捕虫シート(8)との間に虫が飛来することが可能な間隔を存して該捕虫シート(8)を隠す様に装飾板(4)を配備しても可い。
【0005】
矩形枠状の導光板(11)を挟んで、該導光板(11)の端面に対向して紫外線ランプ(12)(12)を配置して紫外線面発光装置(1)を構成し、該該紫外線面発光装置(1)の導光板(11)の開口(10)内に、装飾板(4)を配備しても可い。
【0006】
普通光面発光装置(2)と、該面発光装置(2)の発光面に配備され図柄、文字等の意匠を施した透光性装飾シート(9)とによって装飾板(4)を構成することができる。
【0007】
【作用及び効果】
紫外線が虫を誘引する効果があることは周知であり、紫外線透過性捕虫シート(8)を通じて紫外線が面発光することにより、虫が捕虫シート(8)の近傍に集まり、捕虫シート(8)の粘着剤層(81)に付着する。
粘着剤層(81)に多量に虫が付着すれば、新規の捕虫シート(8)と交換する。
紫外線ランプの回りに、該ランプから離して粘着捕虫シートを配備した場合の誘引粘着捕虫器と本発明の捕虫器と比較したところ、本発明の捕虫器の方が捕虫率が高いことが判った。この理由は、前者の誘引粘着捕虫器では、虫がランプに接しても粘着捕獲されることはないのに対し、本発明の捕虫器は、捕虫シート(8)を通じて紫外線が面発光するから、即ち、誘引される虫にとっては捕虫シート(8)上の粘着剤層(81)そのものから紫外線が面発光しているのと同じであり、発光面が広く、発光面そのものが粘着剤層(81)であるから、紫外線に誘引されて粘着剤層(81)に接近した虫は、身体の一部でも粘着層に接すると捕獲されることになるからである。
【0008】
【発明の実施の形態】
第1実施例 ( 図1乃至図3 )
紫外線面発光装置(1)の前方(図1、図2では上方)に、紫外線面発光装置(1)との間に虫が飛来することが可能な間隔を存して装飾板(4)を配備している。
紫外線面発光装置(1)は、前面開口(31)の浅底の縦長矩形のケース(3)に収容されている。
【0009】
紫外線面発光装置(1)は、アクリル樹脂等の透明度の高い合成樹脂製の導光板(11)と、該導光板(11)の長手方向に沿う両端面の内、一方の端面に対向し且つ該端面に近接して配備された細棒状の冷陰極紫外線ランプ(12)とによって構成される。
紫外線ランプ(12)は「すう光性」(虫が光に集まってくる性質)の良い近紫外線(300〜400nm、実施例では、特に「すう光性」が良いとされている370〜380nm)を発する。

導光板(11)の背面には、レーザ加工等により紫外線ランプ(12)と平行にV溝列(図示せず)が形成されている。該V溝列は、導光板(11)の紫外線ランプ(12)から遠い側の端部にも光が十分に届いて導光板(11)の前面から斑なく面発光させる役割を成すもので、紫外線ランプ(12)から遠ざかる程、隣り合う溝の間隔は狭まっている。
導光板(11)の紫外線入射端面を除く3方の端面及び背面に反射シート(14)(14)が被さっている。
【0010】
ケース(3)の開口(31)に透明カバー板(15)が被せられる。
ケース(3)は開口縁に外向きフランジ(32)を有し、フランジ(32)上に、上辺を除く3辺にU字状に連続する枠板(33)を取り付けている。
枠板(33)の内縁側は、フランジ(32)側が凹んだ凹み段部(34)が形成されている。
ケース(3)の上端に壁掛け用のフック(38)(38)が突設されている。
【0011】
上記ケース(3)の枠板(33)の凹み段部(34)に紫外線透過性捕虫シート(8)の3辺を嵌めて透明カバー板(15)上に捕虫シート(8)が交換可能に配備される。
図3に示す如く、捕虫シート(8)は、ポリエチレンテレフタレート等の透明樹脂シートの片面に粘着剤層(81)を形成したものである。但し、捕虫シート(8)の枠板(33)に嵌まる3縁には粘着剤層は形成されていない。
粘着剤層(81)は透明でなくても紫外線を通すことができるもの、或いは紫外線を通す厚みであれば、従前の斯種捕虫器に使用される粘着剤で形成することができる。
実施例では、捕虫シート(8)を外した場合と、捕虫シート(8)を枠板(33)にセットした状態での面発光の紫外線の波長、照度、輝度に大きな変化がないことを確認した。
粘着剤層(81)には、剥離紙(図示せず)が被さっており、剥離紙を剥がして使用する。
【0012】
上記紫外線面発光装置 ( ) の前方に、昼光色、白光色等の普通光を面発光させる普通光面発光装置(2)が、浅底の縦長矩形のケース ( ) に収容して配備されている。
普通光面発光装置(2)は、アクリル樹脂等の透明度の高い合成樹脂製の導光板(21)と、該導光板(21)の長手方向に沿う両端面の内、一方の端面に対向し且つ該端面に近接して配備された細棒状の冷陰極ランプ(22)とによって構成される。該ランプ(22)は、昼光色、白光色等の普通光を発する
導光板(21)の背面には、前記紫外線面発光装置(1)の導光板(11)と同様にしてV溝列(図示せず)が施され、反射シート(24)が貼り付けられる。
導光板(21)の光入射側端面を除く3つの端面にも反射シート(24)が貼り付けられる。
ランプ(22)には光を導光板(21)の端面へ案内するリフレクター(23)が装着されている。
【0013】
ケース(5)の開口(51)に透明カバー板(25)が被せられる。
ケース(5)は開口縁に外向きフランジ(52)を有し、フランジ(52)上に、上辺を除く3辺にU字状に連続する枠板(53)を取り付けている。
枠板(53)の上からケース全体に被さる表板(16)を被せる。
表板(16)と透明カバー板(25)との間に装飾シート(9)を挿入するシート挿入空間(17)が形成される。
表板(16)は、シート挿入空間(17)の輪郭より少し小さい矩形部分が透明で、外周部は着色等より不透明となっている。
【0014】
装飾シート(9)は、透明シートに文字、図柄等の意匠を施したもので、背面からのランプ(22)の光を透過させることができる。
【0015】
紫外線面発光装置(1)のケース(3)と普通光面発光装置(2)ケース(5)との間に遮蔽板(6)を介在させ、ケース(3)()と遮蔽板(6)の四隅をステー(72)(73)を介してボルト(7)とナット(71)で固定する。
遮蔽板(6)は、紫外線面発光装置(1)からの紫外線が、面発光装置(2)のケース(5)を照射して劣化することを防止するもので、実施例ではアルミニューム板である。
遮蔽板(6)は普通光面発光装置(2)のケース(5)に接近しており、紫外線面発光装置(1)のケース(3)と遮蔽板(6)との間は、虫が飛来するのに十分に余裕がある。
【0016】
然して、紫外線面発光装置(1)のケース(3)上のフック(38)(38)で、捕虫器を壁に掛け、紫外線ランプ(12)及びランプ(22)に通電する。
装飾シート(9)は面発光装置(2)による面発光をバックライトしてその意匠を美しく引き立てる。
紫外線面発光装置(1)からの紫外線の面発光は、装飾シート ( ) を含む装飾板 ( ) に隠れて捕虫器の正面からは見えず、人体に悪影響を与えることはない。
【0017】
普通光面発光装置(2)からの光及び、紫外線面発光装置(1)と普通光面発光装置(2)との間から側部へ洩れる紫外線によって虫が誘引され、捕虫器の近傍に虫が集まる。
昼光色や白色光等の普通光より紫外線が虫を誘引する効果があることは周知であり、捕虫器近傍に集まった虫は、紫外線を面発光させている捕虫シート(8)側に誘引され、捕虫シート(8)の粘着剤層(81)に触れて捕獲される。虫が紫外線発光面側に誘引されることにより、捕虫器の前面である普通光面発光装置(2)の発光面に虫が静止して、糞等で発光面を汚すことはなく、装飾シート(9)の装飾性が損なわれることを防止できる。

図4は、本発明の捕虫器Aと、比較例B、Cの捕虫器の捕虫効果を比較する実験装置を示している。

【0019】
試験方法:供試虫が逃げださない様に作られた試験箱(幅1800mm×高さ600mm×奥行 き600mm)の底面に捕虫器を対向させて設置した。
供試虫の光源間距離は1500mmとした。
光源間の中心に供試虫容器を置いた。供試虫容器はガラス製90mm径シャ ーレで、無作為に選んだ供試虫100固体がはいっている。
光源を点灯させ、10分経過後に供試虫容器の蓋を開けた。供試虫容器の蓋 を開けてから30分経過後に試験を終了して、夫々の粘着面の固体数を計数 した。
捕虫固体数の比較は、以下の組合せで3回づつ行った。

試験ロ…捕虫器Bと捕虫器C
【0020】
結果 :下記の表の通りである。

【表2】
Figure 0003567150
※試験イ、ロにおいて、静止固体数とは捕虫器B、Cの網の近傍で羽ばたいて静止(空中静止)している固体数を目視によって計数したものである。
【0021】
試験イにおいて
供試虫投入30分後、捕虫器A(本発明)の捕獲平均個体数は39.7、捕虫器Cの 捕獲固体数は0で、捕虫器Aは比較品Cより圧倒的に捕獲個体数が多かった。
捕虫器Cでの静止個体数を捕虫器Cにおける誘引固体数とすれば、全体の2割であ る20固体が昼光色蛍光灯に誘引されたことになる。
捕虫器Aでの平均捕獲数を誘引固体数とし、捕虫器Cでの誘引個体数(静止個体数) と比較すれば、39.7:20となり、誘引個体数でも捕虫器Aは捕虫器Cの約2 倍である。
試験ロにおいて
捕虫器Bは、平均1.7固体の捕獲数であり、捕虫器Cは0であった。
供試虫は捕虫器Cの光源側にも飛来したが、粘着剤層に付着するまで接近する固体 は認められなかった。同様に補虫器Bにも供試虫はよく飛来していたが、粘着剤層 に付着するまで接近する固体は少なかった。
誘引固体数(静止固体数)は、捕虫器Bと捕虫器Cを合わせても、投入数の1割強で あったが、捕虫器Bにやや多かった。
【0022】
所見 :捕虫器Aと捕虫器Cとでは、捕虫器Aの方が捕虫器Cの2倍程度の誘引固体数 があったが、捕虫器Cにも全体の2割の誘引固体数が認められた。しかし、捕 虫器Cの昼光色蛍光灯から10cm以内には、逆にあまり供試虫が接近しなく なることが認められ、蛍光灯の付近に配置された粘着シートには供試虫が付着 しない結果となった。
捕虫器Aの方は、光源の表面にまで接近して粘着シートに付着する固体が多か った。
これは、捕虫器Aは、捕虫シート(8)を通じて紫外線が面発光するから、即 ち、誘引される虫にとっては捕虫シート(8)上の粘着剤層(81)から紫外線が面発 光していると同じであるため、発光面が広く、発光面そのものが粘着剤層(81)で あるから、紫外線に誘引されて粘着剤層(81)に接近した虫は、身体の一部でも粘 着層に接すると捕獲されるからと考えられる。
又、捕虫器Aの紫外線ランプ(12)からは、学術文献等で、誘虫効果が高いとさ れる370〜380nmの波長が強く出ていること。面発光の照度、輝度が誘虫 効果を高めていること、特に、導光板(11)の背面がレーザによってV溝加工され ており、これが特有の高い輝度の紫外線を発して誘虫効果を高めると考えられる。
【0023】
実施例2 ( 図5乃至図8 )
紫外線面発光装置(1)と、装飾板(4)を構成する普通光面発光装置(2)を同一平面に配置している。
図6に示す如く、紫外線面発光装置(1)の導光板(11)は、中央部に面発光装置(2)を嵌める矩形の開口(10)を有し、矩形枠状に形成されている。
導光板(11)を挟んで、導光板(11)の長手方向に沿う両側に紫外線ランプ(12)(12)を対向配備し、該紫外線ランプ(12)にリフレクター(13)(13)を被せてケース(3)に収容する。

[Field of the Invention]
TECHNICAL FIELD The present invention relates to an insect trap that emits surface light with ultraviolet light to attract insects and attaches the insects to a sticky insect trap sheet on a light emitting surface.
[0002]
Problems to be solved by the prior art and the invention
2. Description of the Related Art Conventionally, an electric trap that attracts insects by ultraviolet rays, causes a current to flow through a wire mesh disposed in front of the ultraviolet rays, and electrocuts insects in contact with the wire mesh has been used.
The electric shock trap was dangerous because the wire mesh through which the electric current passed was exposed.
The present invention is to clarify an insect trap that can solve the above problem.
[0003]
[Means to solve the problem]
The present invention is a light-induced adhesive insect trap that attracts insects with ultraviolet rays and captures the insects with a sheet having an adhesive layer, wherein an ultraviolet lamp (12) is provided facing an end surface of the transparent light guide plate (11). An ultraviolet light emitting device (1) that emits ultraviolet light from the front surface of the light guide plate without unevenness , and a pressure-sensitive adhesive layer (81) that is exchangeably disposed on the front side of the light emitting surface of the ultraviolet light emitting device (1). And an ultraviolet-permeable insect trap sheet (8).
[0004]
In front of the UV trap, also acceptable to deploy insects at intervals that can fly該捕insect sheet (8) decorative panel so as to hide the (4) between the insect trapping sheet (8) No.
[0005]
Ultraviolet lamps (12) and (12) are arranged opposite to the end surface of the light guide plate (11) with the rectangular frame-shaped light guide plate (11) interposed therebetween to constitute an ultraviolet surface light emitting device (1). A decorative plate (4) may be provided in the opening (10) of the light guide plate (11) of the ultraviolet light emitting device (1).
[0006]
A decorative plate (4) is composed of a normal light surface light emitting device (2) and a translucent decorative sheet (9) provided on the light emitting surface of the surface light emitting device (2) and having designs such as designs and characters. be able to.
[0007]
[Action and effect]
It is well known that ultraviolet rays have an effect of attracting insects, and the ultraviolet rays emit surface light through the ultraviolet-permeable insect trapping sheet (8), so that the insects gather near the insect trapping sheet (8), and the insect trapping sheet (8) It adheres to the pressure-sensitive adhesive layer (81).
If a large amount of insects adhere to the adhesive layer (81), the insect trap sheet (8) is replaced.
Around the ultraviolet lamp, a comparison was made between the attracting insect trap of the present invention and the insect trap of the present invention in which the sticky insect trapping sheet was provided apart from the lamp, and it was found that the insect trap of the present invention had a higher insect catch rate. . The reason for this is that in the former attracting sticky insect trap, the insects are not caught and trapped even when the insects come into contact with the lamp, whereas the insect trap of the present invention emits surface light with ultraviolet light through the insect catching sheet (8). That is, for the insects to be attracted, the ultraviolet light is emitted from the pressure-sensitive adhesive layer (81) itself on the insect catching sheet (8) itself, and the light-emitting surface itself is wide. ), Insects that have been attracted by the ultraviolet rays and approached the adhesive layer (81) will be caught even when a part of the body comes into contact with the adhesive layer.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
First embodiment ( FIGS. 1 to 3 )
A decorative plate (4) is placed in front of the ultraviolet light emitting device (1) (upward in FIGS. 1 and 2) with a space between the ultraviolet light emitting device (1) and the insects that can fly. Deployed.
The ultraviolet surface light emitting device (1) is housed in a vertically elongated rectangular case (3) at the shallow bottom of the front opening (31).
[0009]
The ultraviolet light emitting device (1) includes a light guide plate (11) made of a synthetic resin having high transparency such as an acrylic resin, and one end face of both end faces along the longitudinal direction of the light guide plate (11) and And a thin rod-shaped cold cathode ultraviolet lamp (12) provided in close proximity to the end face.
The ultraviolet lamp (12) is a near-ultraviolet ray (300-400 nm, in the example, 370-380 nm which is considered to have a good "photoluminescence"), which has a good "luminosity" (propagation of insects to light). Emits.
The ultraviolet lamp (12) is provided with a reflector (13) for guiding ultraviolet light to the end face of the light guide plate (11).
On the back surface of the light guide plate (11), a V groove array (not shown) is formed in parallel with the ultraviolet lamp (12) by laser processing or the like. The V-groove row plays a role of allowing the light to sufficiently reach the end of the light guide plate (11) on the side farther from the ultraviolet lamp (12) and causing the front surface of the light guide plate (11) to emit surface light without unevenness, As the distance from the ultraviolet lamp (12) increases, the distance between adjacent grooves decreases.
Reflective sheets (14) and (14) cover the three end faces and the rear face of the light guide plate (11) except for the ultraviolet incident end face.
[0010]
The transparent cover plate (15) is put on the opening (31) of the case (3).
The case (3) has an outward flange (32) at the opening edge, and a U-shaped frame plate (33) is attached to three sides except the upper side on the flange (32).
On the inner edge side of the frame plate (33), a recessed step portion (34) in which the flange (32) side is recessed is formed.
Hooks (38) (38) for wall hanging protrude from the upper end of the case (3).

It is fitted to three sides of the case (3) the frame plate of the recessed step portion (33) (34) to ultraviolet permeable insect sheet (8), the insect trapping sheet on the transparent cover plate (15) (8) is replaced Deployed as possible.
As shown in FIG. 3, the insect catching sheet (8) is formed by forming an adhesive layer (81) on one surface of a transparent resin sheet such as polyethylene terephthalate. However, no pressure-sensitive adhesive layer is formed on the three edges of the insect catching sheet (8) fitted to the frame plate (33).
The pressure-sensitive adhesive layer (81) can be made of a material that is not transparent and can pass ultraviolet rays, or a pressure-sensitive adhesive used in conventional insect traps as long as it has a thickness that allows passage of ultraviolet rays.
In the example, it was confirmed that there was no significant change in the wavelength, illuminance, and luminance of the surface-emitting ultraviolet rays when the insect catching sheet (8) was removed and when the insect catching sheet (8) was set on the frame plate (33). did.
A release paper (not shown) covers the adhesive layer (81), and the release paper is peeled off before use.

FIG. 4 shows an experimental apparatus for comparing the insect trapping effects of the trap A of the present invention and the traps of Comparative Examples B and C.
Figure 0003567150
[0019]
Test method: An insect trap was installed facing the bottom of a test box (1800 mm wide x 600 mm high x 600 mm deep) made so that the insects did not escape.
The distance between the light sources of the test insects was 1500 mm.
The test insect container was placed in the center between the light sources. The test insect container is a 90 mm glass dish containing 100 solids of randomly selected test insects.
The light source was turned on, and after 10 minutes, the lid of the test insect container was opened. The test was terminated 30 minutes after opening the lid of the test insect container, and the number of solids on each adhesive surface was counted.
The comparison of the number of trapped individuals was performed three times in the following combinations.
Test A: insect trap A and insect trap C
Test b: insect trap B and insect trap C
[0020]
Result: as shown in the table below.
[Table 1]
Figure 0003567150
[Table 2]
Figure 0003567150
* In Tests (a) and (b), the number of stationary solids is the number of individuals flapping near the nets of insect traps B and C and standing still (in the air), visually counted.
[0021]
30 minutes after the test insects were injected in Test A, the average number of individuals trapped in insect trap A (the present invention) was 39.7, the number of trapped solids in trap trap C was 0, and trap trap A was overwhelmingly compared with comparative product C. The number of captured individuals was large.
Assuming that the number of stationary individuals in the trap C is the number of attracted solids in the trap C, 20 solids, which are 20% of the total, are attracted to the daylight fluorescent lamp.
The average number of traps in the trap A is taken as the number of attracted individuals and compared with the number of attracted individuals (the number of stationary individuals) in the trap C, the result is 39.7: 20. It is about twice as large as
In Test 2, insect trap B had an average of 1.7 solids trapped, and trap C was zero.
The test insect also flew to the light source side of the insect trap C, but no solid approached until it adhered to the adhesive layer. Similarly, the test insects also flew well into the insect repellent B, but few solids approached until they adhered to the adhesive layer.
The number of attracted solids (the number of stationary solids) was slightly more than 10% of the total number of insect traps B and C even when trapped together, but was slightly higher in insect trap B.
[0022]
Observation: In the trap A and the trap C, the trap A had about twice the number of attracted solids than the trap C, but the trap C also has 20% of the attracted solids. Was. However, within 10 cm from the daylight fluorescent lamp of the insect trap C, it was recognized that the test insects would not approach much, and the test insects did not adhere to the adhesive sheet placed near the fluorescent lamp. The result was.
The trap A had more solids that approached the light source surface and adhered to the adhesive sheet.
This is because the insect trap A emits the surface light of the ultraviolet light through the insect catching sheet (8), so that the attracted insect immediately emits the surface light of the ultraviolet light from the adhesive layer (81) on the insect catching sheet (8). Since the light-emitting surface is wide and the light-emitting surface itself is the adhesive layer (81), insects that have been attracted by the ultraviolet rays and approached the adhesive layer (81) will be viscous even in a part of the body. It is considered that they are captured when they come into contact with the deposition layer.
In addition, the ultraviolet lamp (12) of the insect trap A strongly emits a wavelength of 370 to 380 nm, which is considered to have a high insect-inducing effect in academic literature. It is thought that the illuminance and brightness of the surface light emission enhance the insect-inducing effect, and in particular, the back surface of the light guide plate (11) is V-groove-processed by laser, which enhances the insect-inducing effect by emitting specific high-intensity ultraviolet rays. Can be
