Description

The present invention relates to an insect flight behavior suppression device that suppresses insect behavior using a light source.

Pests such as mosquitoes and bugs are not only unsanitary, but also cause infectious diseases such as dengue fever, so appropriate control is required. It is generally considered that the attraction peak of flying insects including mosquitoes and flies is in the ultraviolet region having a wavelength of about 250 to 410 nm. Therefore, conventionally, in order to control these pests, a device for catching insects using a light source having near-ultraviolet and blue luminescent components has been developed (for example, Patent Document 1).

The insect trap according to Patent Document 1 attracts insects with a cold cathode fluorescent lamp that emits light having near-ultraviolet and blue luminescent components, and captures the attracted insects with an adhesive material. It is also possible to control insects by using a spray-type insecticide, a chemical-heated transpiration-type insecticide, or the like.

Japanese Unexamined Patent Publication No. 2003-333970

However, in the insect trap according to Patent Document 1, since the emission wavelength includes a blue visible light region, light enters the field of vision of humans and animals, which visually obstructs the insect trap, and in some cases, it becomes an obstacle. It causes discomfort. Further, when a spray-type insecticide or a chemical-heated evaporation-type insecticide is used, the chemical is diffused, so that there is a concern that the odor may cause discomfort or the chemical may affect the human body or the like.

The present invention has been made in view of the above problems. The purpose is to provide an insect flight behavior suppression device that does not obstruct the human view, does not cause problems of odor or drug-induced effects on the human body, and can effectively suppress the behavior of insects. Is.

In order to solve the above problems, the insect flight behavior suppression measure according to the present invention includes a light source that emits light having a wavelength component of 780 nm or more and 1350 nm or less, and a control unit that controls the light source. , The light source is blinked at a blinking cycle of 6 Hz or more and 98 Hz or less.

In the insect flight behavior suppression device according to the present invention, the behavior of insects can be suppressed by blinking infrared rays that cannot be seen by humans, so that the behavior of insects is not obstructed. In addition, since no drug is used, problems such as odor and the effect of the drug on the human body do not occur.

(Embodiment 1)
Hereinafter, the first embodiment of the insect flight suppression device according to the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a schematic cross-sectional view of the insect flight behavior suppression device according to the first embodiment. FIG. 2 is a schematic view showing an installation example of the insect flight behavior suppression device according to the first embodiment. FIG. 3 is a block diagram of the insect flight behavior suppression device according to the first embodiment.

[composition]
The insect flight behavior suppression device 1 is a device that suppresses the flight behavior of insects in the insect behavior suppression target area 4 by blinking an infrared light source at a predetermined frequency. By blinking the light source 2 at a predetermined frequency by the insect flight behavior suppression device 1, it is possible to prevent the target insects that are stopped on the wall from flying from the wall, and also to prevent the target insects that are flying from flying. It can be made unstable and dropped on the floor or the ground.

The insect flight behavior suppression device 1 is particularly suitable for suppressing the flight behavior of blood-sucking insects such as mosquitoes, bugs and biting midges, and flying insects. These insects not only cause itching and painful eczema on human skin, but also serve as a source of infectious diseases such as dengue fever. The insect flight behavior suppression device 1 can be used to appropriately control these insects from the human living activity area.

The insect flight behavior suppression device 1 can be installed indoors, for example, in a bedroom, a living room, or any other room as shown in FIG. In addition, the insect flight behavior suppression device 1 can be installed outdoors such as at the entrance of a building or a street light.

Here, the insect behavior suppression target area 4 is an area for controlling insects by suppressing flying behavior, and is an area where a person performs a living activity. When the insect flight behavior suppression device 1 is installed in a room such as a living room or a bedroom, the insect behavior suppression target area 4 may be the entire area of the room, or a specific area in the room (for example, FIG. 2). As shown in the above, when the insect flight behavior suppression device 1 is installed in the bedroom, it may be around the bed or the like).

Further, the insect behavior suppression target area 4 is an area within a predetermined range (for example, a radius of 10 m from the installation location) from the installation location when the insect flight behavior suppression device 1 is installed at the entrance of a building or a street light. The insect behavior suppression target area 4 can be appropriately set by adjusting the irradiation direction, irradiation illuminance, and the like of the light emitted from the light source 2.

The insect flight behavior suppression device 1 includes a light source 2 and a control unit 3. The light source 2 irradiates infrared rays toward the insect behavior suppression target area 4. The light source 2 may be one that emits only infrared rays, or may be a combination of a light source that emits light including infrared rays and a filter that transmits infrared rays.

The control unit 3 controls the light source 2. The control unit 3 controls, for example, the blinking cycle of the light source 2, the emission illuminance, and the like. Here, the blinking cycle is a cycle in which the light source 2 repeatedly turns on and off. The emission illuminance is the illuminance when the light source 2 is emitted from the emission surface.

The exit surface is the exit surface of the light guide plate or the like when the light emitted from the light source 2 is irradiated to the insect behavior suppression target area 4 via the light guide plate or the like. On the other hand, when the area targeted for insect behavior suppression is directly irradiated from the light source 2 without passing through a light guide plate or the like, it is the exit surface of the light source 2.

Further, the insect flight behavior suppression device 1 preferably includes a motion sensor 5. As the motion sensor 5, for example, sensors such as a radio wave sensor, a camera, or the like can be used. By blinking the light source 2 depending on whether or not the human sensor 5 detects that a person exists in the insect behavior suppression target area 4, the insect flight behavior suppression device 1 operates when there is no person or the like. Can be suppressed and power consumption can be reduced.

Specifically, the insect flight behavior suppression device 1 may be operated to blink the light source 2 only while the motion sensor 5 detects a person, or the motion sensor 5 detects a person. The insect flight behavior suppression device 1 may be operated to blink the light source 2 for a predetermined period (for example, 10 minutes) after the disappearance.

Further, the light source 2 may be configured to blink even when the motion sensor 5 detects an animal or the like. Even when the motion sensor 5 detects an animal or the like, the light source 2 blinks so that the insects fly when they adhere to an animal such as a pet and an insect such as a mosquito invades the living activity area of a person. Insects can be controlled by suppressing behavior.

Further, the insect flight behavior suppression device 1 preferably includes an insect sensor 6. The insect sensor 6 predicts the flight direction of the insect. The control unit 3 predicts whether or not the insect will enter the insect behavior suppression target area 4 from the flight direction of the insect predicted by the insect sensor 6.

In this case, it is preferable that the control unit 3 operates the insect flight behavior suppression device 1 to blink the light source 2 only when it is predicted that the insects will enter the insect behavior suppression target area 4. With this configuration, it is possible to suppress the operation of the insect flight behavior suppression device 1 when the insect is not present in the insect behavior suppression target area 4, or the like, and it is possible to reduce power consumption.

The insect sensor 6 is, for example, a camera or the like, and calculates a vector of the insect flight direction from the position of the insect detected by the camera at predetermined time intervals (for example, every 0.1 seconds), and uses this vector to calculate the vector of the insect flight direction. Predict the flight direction.

Further, it is preferable that the insect flight behavior suppressing device 1 is provided with an motion display unit 7 indicating an operating state. Since the light source 2 emits infrared rays that cannot be perceived by the human eye, it is difficult to grasp at first glance whether or not the insect flight behavior suppression device 1 is in operation. Therefore, by providing the motion display unit 7, the operator can at first glance grasp whether or not the insect flight behavior suppression device 1 is in operation.

For the operation display unit 7, various light emitting elements such as a visible light emitting LED (Light Emitting Diet: light emitting diode), an EL element such as an organic EL (Electro Luminescence), and an inorganic EL can be used.

Further, the insect flight behavior suppression device 1 preferably includes an illuminance sensor (not shown) for measuring the average irradiance of the surrounding environment. The irradiance of the ambient environment is determined by measuring the average irradiance on the irradiation surface facing the light source 2. Therefore, the illuminance sensor measures the illuminance on the irradiated surface.

Here, the irradiation surface is a surface substantially perpendicular to the irradiation direction from the light source 2. The irradiation surface is, for example, the upper surface of a dining table or the floor when the light source 2 is installed on the ceiling surface, and the opposite surface when the light source 2 is installed on the wall surface. The wall surface, etc. Further, when the light source 2 is installed on the floor surface, it is the ceiling surface or the like.

By using the illuminance sensor, the control unit 3 can control the illuminance of the light source 2 according to the ambient environment such as the illuminance of other lighting devices, and the insects can control the illuminance of the light source 2 even in various environments where the illuminance of the surrounding environment is different. The effect of suppressing flying behavior can be obtained.

Further, the insect flight behavior suppression device 1 is connected to an external electric power by a power line 10. The electric power for operating the insect flight behavior suppression device 1 is supplied from an external electric power through the power line 10. The insect flight behavior suppression device 1 may be provided with a battery and may be configured to operate by supplying electric power from the battery.

[light source]
The light source 2 irradiates infrared rays toward the insect behavior suppression target area 4. The light source 2 irradiates light having a wavelength component in the infrared region of 780 nm or more and 1350 nm or less while blinking. The light source 2 irradiates infrared rays with a blinking cycle of 6 Hz or more and 98 Hz or less.

In the first embodiment, the light source 2 is a light source having a relatively limited emission wavelength range such as an LED or an EL element, and uses a light emitting element that emits light having a wavelength in the infrared region. However, what can be used as the light source 2 is not limited to the above-mentioned light emitting element and the like. For example, a light source 2 may be a combination of an incandescent lamp, a halogen lamp, a xenon lamp, or the like that emits light in a relatively wide wavelength range including an infrared region and a filter that transmits infrared rays. ..

The blinking cycle of the light source 2 is adjusted by the frequency adjusting unit 8 in the range of 6 Hz or more and 98 Hz or less by the output from the control unit 3. As the frequency adjusting unit 8, for example, a function generator, a standard signal generator, or the like can be used.

The irradiance from the light source 2 at the end of the insect behavior suppression target area 4 ^{is preferably 5 μW / cm 2} or more and 1 W / cm ² or less. If the irradiance at the head of the insect to be suppressed from flying behavior is 5 μW / cm ² or more and 1 W / cm ² or less, the flying behavior of the insect can be effectively suppressed. Therefore, if the illuminance from the light source 2 at the end of the insect behavior suppression target area 4 is 5 μW / cm ² or more and 1 W / cm ² or less, the insect flight behavior at the end of the insect behavior suppression target area 4 Can also be effectively suppressed.

Here, the end portion of the insect behavior suppression target area 4 is the portion of the insect behavior suppression target area 4 farthest from the light source 2. For example, when the insect flight behavior suppression device 1 is installed indoors and the insect behavior suppression target area 4 covers the entire room, it is the corner portion of the room farthest from the light source 2.

[Control unit]
The control unit 3 controls the emission illuminance of the light source 2, the blinking cycle, and the like. The control unit 3 is, for example, a CPU or the like. The control unit 3 uses, for example, the above-mentioned illuminance sensor in order to control the emission illuminance of the light source 2.

The method of adjusting the irradiance by the control unit 3 is not limited to the method of using the illuminance sensor. For example, the control unit 3 is equipped with a clock function or a timer function without using an illuminance sensor, and the irradiation illuminance from the light source 2 is set to a predetermined value or more in the daytime time zone of the day, and the nighttime time zone. May control the irradiation illuminance from the light source 2 to be equal to or less than a predetermined value.

Further, the control unit 3 outputs a command to the frequency adjustment unit 8 in order to control the blinking cycle of the light source 2. Then, the blinking cycle of the light source 2 is adjusted by the frequency adjusting unit 8 within the range of 6 Hz or more and 98 Hz or less.

Regarding the control of the blinking cycle, for example, the control unit 3 may control the light source 2 to blink at a predetermined frequency within the range of 6 Hz or more and 98 Hz or less at all times during the operation of the insect flight behavior suppression device 1. .. However, it is preferable that the control unit 3 controls the light source 2 to blink while changing the blinking cycle within the range of 6 Hz or more and 98 Hz or less.

When the light source 2 blinks for a long period of time while the blinking cycle of the light source 2 is always fixed at a constant frequency, some insects may become accustomed to the flight behavior suppression effect of the insect flight behavior suppression device 1. Therefore, by making the light source 2 blink while changing the blinking cycle of the light source 2 within the range of 6 Hz or more and 98 Hz or less, it is possible to prevent insects from becoming accustomed to the flight behavior suppressing effect.

Further, the control unit 3 may use the timer function to control the insect flight behavior suppression device 1 so as to switch the operation of the insect flight behavior suppression device 1 depending on the time zone. Specifically, the control unit 3 operates the insect flight behavior suppression device 1 only during the time when the person is active in the place where the insect flight behavior suppression device 1 is installed, and the control unit 3 operates the insect flight behavior suppression device 1 only during the time when the person is active. Can be controlled so as not to operate the insect flight behavior suppression device 1.

For example, when the insect flight behavior suppression device 1 is installed in the bedroom, the insect flight behavior suppression device 1 is operated only during the nighttime when a person uses the bedroom for sleeping, and the insect flight behavior suppression device 1 is operated during the daytime when the person does not use the bedroom. It is preferable that the insect flight behavior suppression device 1 is not operated during this time period.

If the insect flight behavior suppression device 1 is controlled in this way, the insect flight behavior suppression device 1 is installed only during the time when insects need to be controlled, such as the time when a person is active in daily life. 1 can be operated, and the energy consumed by the insect flying behavior suppression device 1 can be reduced.

Further, the control unit 3 uses the timer function and the motion sensor 5 to elapse a predetermined time (for example, 15 minutes) after the motion sensor 5 detects that a person exists in the insect behavior suppression target area 4. The light source 2 may be controlled to blink until the light source 2 is blinked.

By blinking the light source 2 depending on whether or not the human sensor 5 detects that a person exists in the insect behavior suppression target area 4, the insect flight behavior suppression device 1 operates when there is no person or the like. Can be suppressed and power consumption can be reduced.

Further, it is preferable that the control unit 3 blinks the light source 2 for 40 to 55 minutes out of 60 minutes and does not blink the light source 2 for 20 to 5 minutes. By providing a pause period for the blinking of the light source 2, it is possible to irradiate the blinking of the light source 2 even for insects that have come out of the shadow during this pause period, and it is possible to suppress the flight behavior of the insects more efficiently. Can be done.
