The present inventor has obtained the following recognition regarding a pest control apparatus for reducing pests.
For example, Anopheles mosquito, a kind of mosquito, causes great damage to mankind by mediating diseases such as malaria. There are reports that malaria infects about 200 million people worldwide, of which about 750,000 die worldwide. Although it is conceivable to use a drug to reduce the number of mosquitoes, the range in which the drug can be sprayed is actually limited, and there is a problem of drug resistance in the long term, and its effect is limited. In addition, it is conceivable to attract mosquitoes and remove them by electric shock, but there is a problem that a large amount of money is required to install a device for this purpose over a wide area.

  Such a problem can occur not only for mosquitoes but also for other types of pests. From this, the present inventor has recognized that the pest control apparatus has room for improvement from the viewpoint of effectively reducing pests.

  An object of the present invention has been made in view of such problems, and is to provide a light irradiation apparatus capable of effectively reducing pests.

  In order to solve the above problems, a light irradiation apparatus according to an aspect of the present invention is a light irradiation apparatus for irradiating a pest with light, and includes a collection chamber and an attraction for attracting the pest to the collection chamber. And a first irradiation unit that irradiates the collection chamber with first irradiation light including light having a wavelength characteristic capable of sterilizing pests.

  According to this aspect, it is possible to irradiate light having a wavelength characteristic capable of sterilizing a pest that has been attracted.

  Another embodiment of the present invention is also a light irradiation device. This device is a light irradiation device for irradiating light to at least one of a pest egg, a pest larva and a pest puppy, a container for causing the pest to lay eggs, a pest egg in the container, A first irradiation unit that irradiates at least one of a pest larvae and a pest puppet that includes first irradiation light including light having a wavelength characteristic capable of being sterilized.

  Note that any combination of the above-described constituent elements, and those obtained by replacing the constituent elements and expressions of the present invention with each other between methods and systems are also effective as an aspect of the present invention.

  ADVANTAGE OF THE INVENTION According to this invention, the light irradiation apparatus which can reduce a pest effectively can be provided.

It is a schematic diagram of the side view of the light irradiation apparatus which concerns on 1st Embodiment. It is a block diagram which shows an example of a structure of the light irradiation apparatus of FIG. It is a flowchart explaining an example of operation | movement of the light irradiation apparatus of FIG. It is a schematic diagram of the side view of the light irradiation apparatus which concerns on 2nd Embodiment. It is a block diagram which shows an example of a structure of the light irradiation apparatus of FIG. It is a flowchart explaining an example of operation | movement of the light irradiation apparatus of FIG.

The inventor has studied a method for effectively reducing pests using a light irradiation device, and has obtained the following knowledge.
For example, a method of attracting a target pest by using a guide light that emits ultraviolet rays from blue, and electric shock at a high voltage to eliminate it is conceivable. However, although this method can control pests around the device, it is not suitable for pest control over a wide range.

  In addition, a method of releasing a large amount of the pests reared in nature by using radiation to eliminate the reproductive function. However, with this method, there are problems such as requiring a large facility for rearing large amounts of pests, problems of damage caused by artificially reared pests, and problems that require huge costs for facilities and equipment for using radiation. It is done. In fact, it is difficult to solve costs and other problems when trying to implement such a method for endemic areas such as malaria, which is not practical.

  From this, the present inventor has found a method of irradiating a pest attracted in nature with a predetermined action light to infertility while keeping a part of the pest alive and releasing the infertile pest to nature. In this method, the infertile pest returns to the natural world and reproductive activities with other pests can reduce the chances of normal pest reproduction and suppress the birth of the next generation pest. An apparatus for realizing this method can be configured at low cost, and is easy to handle because it does not use radiation. Further, by providing this device with functions of power generation and power storage, it can be operated for a long time with almost no maintenance. Due to such characteristics, the device can be installed in undeveloped areas such as endemic areas such as malaria.

Furthermore, the present inventor has found that this idea can also be applied to pest eggs, larvae and pupae. For example, it may be possible to lay eggs on a pest attracted from the natural world and irradiate the eggs with action light. That is, it is conceivable to continuously irradiate the action light during the period of the state of the insect pest eggs, hatched larvae and pupae. Pest eggs, larvae and pupae have a very limited range of movement, so it is possible to continue irradiation with action light for a long time. They can be sterilized efficiently.
The embodiment has been devised based on such thoughts, and a specific configuration thereof will be described below.

The present invention will be described below based on preferred embodiments with reference to the drawings. In the embodiment and the modification, the same or equivalent components and members are denoted by the same reference numerals, and repeated descriptions are appropriately omitted. In addition, the dimensions of the members in each drawing are appropriately enlarged or reduced for easy understanding. Also, in the drawings, some of the members that are not important for describing the embodiment are omitted.
In addition, terms including ordinal numbers such as first and second are used to describe various components, but this term is used only for the purpose of distinguishing one component from other components. However, the constituent elements are not limited.

The light irradiation apparatus 100 mainly includes a first irradiation unit 10, an attracting unit 20, a control unit 30, a housing 40, and a power supply unit 50. The attracting unit 20 attracts pests. The 1st irradiation unit 10 irradiates the 1st irradiation light 12e containing the light of the wavelength characteristic and intensity which can sterilize a pest. The housing 40 supports the first irradiation unit 10 and the attracting unit 20. The power supply unit 50 supplies power to the first irradiation unit 10 and the attracting unit 20. The control unit 30 controls the operation of the first irradiation unit 10.

(First irradiation unit)
The 1st irradiation unit 10 is accommodated in the accommodating part 40b below the collection chamber 40c of the housing | casing 40 mentioned later, and outputs the 1st irradiation light 12e toward the collection chamber 40c. The first irradiation unit 10 may be provided so as to output at least a part of the first irradiation light 12e to the collection chamber 40c of the housing 40. In the example of FIG. 1, the first irradiation unit 10 is configured such that most of the first irradiation light 12e is output toward the collection chamber 40c.

  The 1st irradiation unit 10 is provided with the light source part 12 which emits the 1st irradiation light 12e. The light source unit 12 outputs the first irradiation light 12e having a wavelength characteristic that has an effect of reducing the reproductive function of the pest. The light source unit 12 may output light having a single wavelength characteristic or may output light having a plurality of wavelength characteristics. The 1st irradiation light 12e contains the medium wavelength ultraviolet rays (UVB / C wave) of 250 nm-320 nm which has the effect of reducing the reproductive function of a pest. In addition, the medium wavelength ultraviolet rays (UVB / C wave) of 250 nm to 320 nm can also have an effect of killing pests by adjusting the illuminance.

  The light source unit 12 includes a substrate 12c and a plurality of light emitting elements 12b arranged on the substrate 12c. The plurality of light emitting elements 12b are arranged, for example, linearly or in a matrix on the substrate. As the light emitting element 12b, light emitting elements based on various principles can be employed. In the light irradiation device 100, an LED (Light Emitting Diode) that emits ultraviolet rays is employed as the light emitting element 12b. As such an LED, an aluminum gallium nitride (AlGaN) LED can be used.

(Casing)
The housing 40 is a base that supports the first irradiation unit 10 and the attracting unit 20. In the example of FIG. 1, the housing 40 includes a housing portion 40b, a collection chamber 40c, and a light transmissive member 40g. As an example, the accommodating portion 40 b is provided in the lower part of the housing 40, and the collection chamber 40 c is provided on the upper side of the housing 40. The accommodating portion 40b and the collection chamber 40c are partitioned by a translucent member 40g. Although there is no special limitation in the shape of the housing | casing 40, in the example of FIG. 1, the housing | casing 40 exhibits a substantially rectangular parallelepiped shape as a whole. The housing 40 may be a box-shaped collection chamber.

(Container)
The accommodating part 40b mainly accommodates the first irradiation unit 10, the storage battery 54, and the control part 30. If the inclusions of the accommodating portion 40b such as the first irradiation unit 10 get wet, it can cause functional deterioration and failure such as reduction in light output. Therefore, in the light irradiation apparatus 100, the housing portion 40b has an outer shell 40d that surrounds the housing space. The material forming the outer shell 40d can be selected from various resin materials and metal materials according to desired characteristics such as durability. Although there is no special restriction | limiting in the shape of the outer shell 40d, it is a substantially rectangular parallelepiped shape in the example of FIG. An opening for attaching the translucent member 40g is provided on the surface of the accommodating portion 40b on the collection chamber 40c side. The accommodating part 40b may have a waterproof structure so that the member included by rain etc. may not get wet.

(Translucent member)
If a foreign substance adheres to the inclusion in the accommodating portion 40b such as the first irradiation unit 10, it may cause a decrease in light output or a failure. Therefore, in the light irradiation device 100, the translucent member 40g is provided on the upper side of the accommodating portion 40b. The translucent member 40g can suppress the entry of foreign matter such as dead leaves and dead insect pests inside the accommodating portion 40b. The translucent member 40g transmits the first irradiation light 12e emitted from the first irradiation unit 10 to the collection chamber 40c side. In the example of FIG. 1, the translucent member 40g is formed of a rectangular thin plate-like quartz glass. The translucent member 40g may be formed of a material different from quartz glass. The translucent member 40g may be formed of, for example, a fluorine resin or a silicone resin.

(Collection room)
It is desirable that the first irradiation light 12e is concentrated and irradiated in a space that attracts and collects target pests. Therefore, the light irradiation apparatus 100 includes a collection chamber 40c in order to define a space for collecting pests. It is desirable that the collection chamber 40c can easily enter and exit the pest. In the example of FIG. 1, the collection chamber 40c is configured by a frame 40f that borders a substantially rectangular parallelepiped space. The frame 40f includes four vertical frames 40h extending upward from the four corners of the accommodating portion 40b, and four horizontal frames 40k spanned in the horizontal direction between the upper ends of the vertical frames 40h. The vertical frame 40h may be a support. The four horizontal frames 40k are combined into a rectangle in plan view. The horizontal frame 40k may be a beam. Between the frames 40f, the frame 40f is opened so as not to prevent the entry and exit of pests. A part of the collection chamber 40c may be covered with a covering. The 2nd irradiation unit 22 and the electric power generation part 52 are being fixed to the upper side of the four horizontal frames 40k. The collection chamber 40c may be provided with a reinforcing member such as a brace to suppress deformation of the frame 40f, or a wall may be provided on a part of the surface.

(Invitation Department)
The attracting unit 20 attracts pests from around the light irradiation device 100. In the example of FIG. 1, the attracting unit 20 includes a second irradiation unit 22 and a catalyst unit 26, and attracts pests to the collection chamber 40c. The 2nd irradiation unit 22 outputs the 2nd irradiation light 24e of the wavelength characteristic which can attract a pest. The catalyst unit 26 generates a gas having an action of attracting pests when irradiated with predetermined light.

(Second irradiation unit)
The 2nd irradiation unit 22 is attached to the upper part or side part of the collection chamber 40c, and outputs the 2nd irradiation light 24e. The second irradiation unit 22 may be provided so as to output a part of the second irradiation light 24 e to the collection chamber 40 c of the housing 40. In order to effectively attract pests, at least a part of the second irradiation light 24e may be output to the outside of the housing 40. In the example of FIG. 1, the second irradiation unit 22 is configured such that a part of the second irradiation light 24 e is output to the collection chamber 40 c and another part is output to the outside of the housing 40. . In the example of FIG. 1, the 2nd irradiation unit 22 has shown the example attached to the upper part and side part of the collection chamber 40c, but the 2nd irradiation unit 22 is one side of the upper part and side part of the collection chamber 40c. It may be attached to.

  The first irradiation unit 10 and the second irradiation unit 22 output the first irradiation light 12e and the second irradiation light 24e toward the collection chamber 40c, so that the collection chamber 40c of the housing 40 has an inside. A region irradiated with the first irradiation light 12e and the second irradiation light 24e is formed. Since it has such an area | region, the light irradiation apparatus 100 can irradiate the 1st irradiation light 12e efficiently to the pest attracted to the 2nd irradiation light 24e, and entered into the collection chamber 40c.

  The 2nd irradiation unit 22 is provided with the light source part 24 which emits the 2nd irradiation light 24e. The light source unit 24 outputs the second irradiation light 24e having a wavelength characteristic that has an effect of attracting pests. The light source unit 24 may output light having a single wavelength characteristic or may output light having a plurality of wavelength characteristics. The 2nd irradiation light 24e contains 350 nm-400 nm long wavelength ultraviolet rays (UVA wave), visible light, etc. with a high pest attraction effect.

  The light source unit 24 includes a substrate 24c and a plurality of light emitting elements 24b arranged on the substrate 24c. The plurality of light emitting elements 24b are arranged, for example, in a straight line or a matrix on the substrate. As the light emitting element 24b, light emitting elements based on various principles can be employed. In the light irradiation device 100, an LED (Light Emitting Diode) that emits ultraviolet rays is employed as the light emitting element 24b. As such an LED, an aluminum gallium nitride (AlGaN) LED can be used.

(Catalyst part)
The catalyst unit 26 generates gas for attracting pests in response to predetermined light. The catalyst unit 26 includes a mesh-like base 26c disposed in the optical path of the first irradiation light 12e in the collection chamber 40c, and a photocatalyst 26b applied to the base 26c. The photocatalyst 26b reacts with at least one of the 1st irradiation light 12e and the 2nd irradiation light 24e, produces a photocatalytic reaction, and produces | generates the carbon dioxide which a mosquito etc. like. As such a photocatalyst 26b, a known catalyst such as a titanium dioxide-based catalyst can be used. Since a region where the concentration of the generated carbon dioxide is relatively high is formed in the vicinity of the catalyst portion 26, pests can be attracted to this region.

  The attracting unit 20 uses the second irradiation light 24e output to the outside of the housing 40 to cause the pest attracted to the periphery of the light irradiation device 100 to generate the inside of the collection chamber 40c by carbon dioxide generated in the catalyst unit 26. The catalyst portion 26 can be guided to the vicinity. By providing the catalyst part 26 in the optical path of the first irradiation light 12e, the first irradiation light 12e can be efficiently irradiated to the pest attracted in the vicinity of the catalyst part 26.

(Power supply part)
The power supply unit 50 supplies power to the first irradiation unit 10 and the second irradiation unit 22. The power supply unit 50 may supply power internally based on power supplied from a commercial power supply. However, in the light irradiation device 100, the power supply unit 50 supplies power generated internally. . The power supply unit 50 includes a power generation unit 52 that outputs power, a storage battery 54 that stores at least part of the power from the power generation unit 52, and power from the power generation unit 52 or the storage battery 54 for the first irradiation unit 10 and the second irradiation unit. 22 and the power supply part 56 supplied to the control part 30 are included.

  The power generation unit 52 can use power generation mechanisms and elements based on various known principles. In the example of FIG. 1, the power generation unit 52 includes a photovoltaic module 52 b that converts light energy into electric power using the photovoltaic effect. The light irradiation device 100 can be operated even in an area where commercial power cannot be used because power is generated using sunlight. The photovoltaic module 52b is desirably arranged in a state where more sunlight can be used. In the example of FIG. 1, the photovoltaic module 52 b is disposed on the top of the housing 40.

  The working hours of pests are not limited to daytime, for example, pests are active at night. Therefore, the light irradiation device 100 includes a storage battery 54 that stores the power generated by the power generation unit 52. The storage battery 54 can use power storage mechanisms and elements based on various known principles. In the example of FIG. 1, the light irradiation device 100 employs a lithium ion battery as the storage battery 54. The storage battery 54 is desirably not exposed, and is disposed inside the accommodating portion 40b in the example of FIG.

  The light irradiation device 100 includes a communication unit 68, a failure detection unit 58, a timer 60, an illuminance sensor 62, a temperature sensor 64, and a GPS sensor 66. The communication unit 68 communicates with the management server via a wireless communication network such as the Internet, transmits information, and receives an operation command.

  The failure detection unit 58 diagnoses the operation status and deterioration status of components such as the first irradiation unit 10, the second irradiation unit 22, the power generation unit 52, and the storage battery 54 of the light irradiation device 100, and the diagnosis result is a control unit Output to 30. The control unit 30 determines whether the operations of the first irradiation unit 10 and the second irradiation unit 22 are possible according to the diagnosis result acquired from the failure detection unit 58. Further, the control unit 30 uploads the diagnosis result to the management server on the wireless communication network via the communication unit 68. The administrator can refer to the uploaded results.

  Pests have different activity times depending on the type. There are two types of pests, one that becomes active from the evening to the night, and the other that activates while it is bright and breathes in at night. For this reason, the light irradiation apparatus 100 includes a timer 60. The timer 60 detects a preset time and outputs the detection result to the control unit 30. The control unit 30 refers to the detection result of the timer 60 and controls the operations of the first irradiation unit 10 and the second irradiation unit 22. The timer 60 can use a timer mechanism or an element based on a known principle.

  There are types of pests whose activity state changes according to the brightness of the surroundings. For this reason, the light irradiation device 100 includes an illuminance sensor 62. The illuminance sensor 62 detects the brightness around the light irradiation device 100 and outputs the detection result to the control unit 30. The controller 30 controls the operations of the first irradiation unit 10 and the second irradiation unit 22 with reference to the detection result of the illuminance sensor 62. For example, the first irradiation unit 10 and the second irradiation unit 22 can be operated if they are within a preset brightness range, and these operations can be stopped if they are outside the range. As the illuminance sensor 62, an illuminance sensor based on a known principle can be used.

  There are types of pests that slow down when the ambient temperature is too high or too low. For this reason, the light irradiation apparatus 100 includes a temperature sensor 64. The temperature sensor 64 detects the ambient temperature around the light irradiation device 100 and outputs the detection result to the control unit 30. The control unit 30 refers to the detection result of the temperature sensor 64 and controls the operations of the first irradiation unit 10 and the second irradiation unit 22. For example, the first irradiation unit 10 and the second irradiation unit 22 can be operated if they are within a preset temperature range, and these operations can be stopped if they are outside the range. As the temperature sensor 64, a temperature sensor based on a known principle can be used.

  It is conceivable that the light irradiation apparatus 100 is carried to a position different from the initial position for some reason. In addition, there may be a case where it is desired to detect the exact position of the light irradiation device 100 for maintenance or replacement. For this reason, the light irradiation device 100 includes a GPS sensor 66. The GPS sensor 66 detects the three-dimensional position of the light irradiation device 100 by the satellite positioning system and outputs the detection result to the control unit 30. The control unit 30 determines whether or not the first irradiation unit 10 and the second irradiation unit 22 can operate according to the detection result acquired from the GPS sensor 66. Further, the control unit 30 uploads the detection result to the management server on the wireless communication network via the communication unit 68. The administrator can refer to the uploaded results. The administrator can use the three-dimensional position acquired from the GPS sensor 66 as identification information of the individual of the light irradiation device 100 when many light irradiation devices are installed. As the GPS sensor 66, a sensor based on the well-known GPS (Global Positioning System) can be used.

(Control part)
Next, the control unit 30 will be described. Each block of the control unit 30 shown in FIG. 2 can be realized in hardware by an element and a mechanical device such as a CPU (Central Processing Unit) of a computer, and in software by a computer program or the like. However, here, functional blocks realized by their cooperation are depicted. Therefore, it is understood by those skilled in the art who have touched this specification that these functional blocks can be realized in various forms by a combination of hardware and software. This description regarding the control unit 30 is similarly applied to the control unit 230 described later.

  The control unit 30 controls the operations of the first irradiation unit 10 and the second irradiation unit 22 according to the detection results acquired from the failure detection unit 58, the timer 60, the illuminance sensor 62, and the temperature sensor 64. The control unit 30 includes a first acquisition unit 30b, a second acquisition unit 30c, a third acquisition unit 30d, a fourth acquisition unit 30e, a fifth acquisition unit 30g, a communication control unit 30h, and a first irradiation control unit. 30j, the 2nd irradiation control part 30k, and the charge control part 30m.

  The first acquisition unit 30 b acquires the diagnosis result from the failure detection unit 58. The second acquisition unit 30 c acquires the detection result from the timer 60. The third acquisition unit 30 d acquires the detection result from the illuminance sensor 62. The fourth acquisition unit 30 e acquires the detection result from the temperature sensor 64. The fifth acquisition unit 30 g acquires the detection result from the GPS sensor 66. The communication control unit 30 h acquires reception information from the communication unit 68 and transmits transmission information via the communication unit 68. The first irradiation control unit 30j controls the first irradiation unit 10. The second irradiation control unit 30 k controls the second irradiation unit 22. The charging control unit 30m controls the charging of the storage battery 54 by controlling the power feeding unit 56.

(Operation)
Next, an example of operation | movement of the light irradiation apparatus 100 comprised in this way is demonstrated. FIG. 3 is a flowchart for explaining an example of the operation of the light irradiation apparatus 100, and shows a process S100 related to this operation. The process S100 includes an operation of performing autonomous control according to the self-diagnosis and the detection result of each sensor after the light irradiation apparatus 100 starts the operation.

  When the operation is started, the control unit 30 acquires the detection result of the failure detection unit 58 and determines whether or not a failure is detected (step S102). When the failure detection unit 58 detects a failure (Y in step S102), the control unit 30 acquires a three-dimensional position from the GPS sensor 66 (step S104).

  When the three-dimensional position is acquired, the control unit 30 transmits the detected failure status as failure information to the management server (not shown) on the wireless communication network (not shown) via the communication unit 68 together with the three-dimensional position information. (Step S106). If failure information etc. are transmitted, the control part 30 will complete | finish process S100. The administrator can acquire failure information of the light irradiation apparatus 100 by referring to the management server.

  If the failure detection unit 58 has not detected a failure (N in step S102), the control unit 30 refers to the timer 60 and determines whether or not the operation start time has passed (step S108). When the operation start time has not passed (N in Step S108), the control unit 30 returns the process to the beginning of Step S102 and repeats the processes from Step S102 to S108.

  When the operation start time has passed (Y in Step S108), the control unit 30 refers to the illuminance sensor 62 to determine whether or not the operation start illuminance is within the range (Step S108). When it is not within the range of the operation start illuminance (N in Step S110), the control unit 30 returns the process to the beginning of Step S102 and repeats the processes from Step S102 to S110.

  When it is within the range of the operation start illuminance (Y in Step S110), the control unit 30 refers to the temperature sensor 64 and determines whether or not it is within the range of the operation start temperature (Step S112). When it is not within the range of the operation start temperature (N in Step S112), the control unit 30 returns the process to the beginning of Step S102 and repeats the processes from Step S102 to S112.

  When it is within the range of the operation start temperature (Y in Step S112), the control unit 30 acquires a three-dimensional position from the GPS sensor 66 (Step S114). When the three-dimensional position is acquired, the control unit 30 transmits the three-dimensional position information and the operation start information to the management server on the wireless communication network via the communication unit 68 (step S116).

  If operation start information etc. are transmitted, control part 30 will start operation of the 1st irradiation unit 10 and the 2nd irradiation unit 22 (Step S118). When this step is started, as shown in FIG. 1, the first irradiation unit 10 emits the first irradiation light 12e, and the second irradiation unit 22 emits the second irradiation light 24e. By irradiating the photocatalyst 26b with these irradiation lights, the carbon dioxide concentration around the photocatalyst 26b increases. In response to the second irradiation light 24e emitted toward the outside, the pest M (a) is attracted to the periphery of the light irradiation apparatus 100.

  The insect pest M (a) attracted to the periphery of the light irradiation device 100 reacts with the second irradiation light 24e irradiated into the collection chamber 40c and the carbon dioxide concentration in the vicinity of the photocatalyst 26b, so that the inside of the collection chamber 40c. Enter. The pest M (b) that has entered the collection chamber 40c is sterilized by being irradiated with the first irradiation light 12e while drifting in the vicinity of the catalyst unit 26. If the illuminance of the first irradiation light 12e is too low, the sterilization rate of the pest M (b) is lowered. If the illuminance of the first irradiation light 12e is too high, the death rate of the pest M (b) due to irradiation increases. The illuminance of the first irradiation light 12e can be set by experiment according to a desired sterility rate and a desired mortality rate. As an example, the illuminance of the first irradiation light 12e may be adjusted so that the sterilization rate of the irradiated pest M (b) is 30% or more. As an example, the illuminance of the first irradiation light 12e may be adjusted so that the survival rate of the irradiated pest M (b) is 60% or more.

  Moreover, the wavelength characteristic of the 1st irradiation light 12e can be set by experiment according to a desired sterilization rate and a desired survival rate. The sterilization rate depends on the wavelength characteristics of the irradiated light. For example, the sterilization rate is high when the peak wavelength of the irradiation light is 270 nm. However, this wavelength may act on genes other than those related to reproduction, and it is also possible to use a wavelength on the long wavelength side in which a sterilization effect is suppressed in consideration of a desired survival rate. The wavelength characteristic of the first irradiation light 12e may be set according to the type and size of the target pest. As an example, light having a wavelength in the vicinity of 300 nm, which is a long wavelength of about 30 nm to a wavelength having a high effect may be used.

  The pest M (c) that has left the collection chamber 40c returns to nature and performs breeding activities with normal individuals, but the next generation of pests will not be born, and by reducing the breeding opportunities of other individuals, As a result, generation of next-generation pests is suppressed. It can be expected that pests are gradually reduced by continuing such an operation for a long time.

  When the operation of the irradiation unit is started, the control unit 30 refers to the timer 60 and determines whether or not the operation end time has passed (step S120). When the operation end time has not passed (N in Step S120), the control unit 30 returns the process to the beginning of Step S120 and repeats the process of Step S120. That is, the operation of the irradiation unit is continued until the operation end time is passed.

  When the operation end time has passed (Y in Step S120), the control unit 30 ends the operations of the first irradiation unit 10 and the second irradiation unit 22 (Step S122). When the operation of the irradiation unit is completed, the control unit 30 transmits the three-dimensional position information and the operation end information to the management server on the wireless communication network via the communication unit 68 (step S124).

  If information is transmitted, control part 30 will return processing to the head of Step S102, and will repeat processing of Step S102-Step S124. The above-described process S100 is merely an example, and other steps may be added, some steps may be changed or deleted, and the order of steps may be changed.

  Next, the operation and effect of the light irradiation apparatus 100 according to the first embodiment configured as described above will be described. According to this configuration,

  The light irradiation device 100 according to the first embodiment is a light irradiation device for irradiating a pest with light, and includes a collection chamber 40c, an attracting unit 20 for attracting the pest to the collection chamber 40c, and a capture unit. The collection chamber 40c includes a first irradiation unit 10 that irradiates a first irradiation light 12e including light having a wavelength characteristic capable of sterilizing pests. According to this structure, since the 1st irradiation light 12e is irradiated to the pest attracted to the collection chamber 40c, a pest can be sterilized efficiently. When the infertile pests are released to the natural world, they breed with other individuals, but because they are infertile, they do not lay eggs and the pest breeding is suppressed. In addition, pests that have been sterilized can be prevented from breeding by reducing the chances of breeding normal individuals by performing breeding activities. By using such a device for a long period of time, the number of pests gradually decreases, and eventually eradication can be expected. The light irradiation apparatus 100 has a simple configuration, can be manufactured at a low cost, and can be installed in a jungle zone.

  In the light irradiation apparatus 100 according to the first embodiment, the attracting unit 20 includes a second irradiation unit 22 that outputs the second irradiation light 24e having a wavelength characteristic capable of attracting pests, and the second irradiation unit 22 includes: The first irradiation unit 10 outputs at least part of the second irradiation light 24e to the outside of the collection chamber 40c, and the first irradiation unit 10 outputs at least part of the first irradiation light 12e to the inside of the collection chamber 40c. It is provided to do. According to this structure, since the 2nd irradiation light 24e for attracting a pest is output to the exterior of the collection chamber 40c, it can be visually recognized from a pest even from a distance. For this reason, it becomes possible to attract a pest from a wide range around the light irradiation device 100.

  In the light irradiation apparatus 100 according to the first embodiment, a region irradiated with the first irradiation light 12e and the second irradiation light 24e is formed inside the collection chamber 40c. According to this structure, by having the area | region where both irradiation light is collated, the 1st irradiation light 12e is efficiently irradiated to the pest attracted to the 2nd irradiation light 24e and entered into the collection chamber 40c. Can do.

  In the light irradiation apparatus 100 according to the first embodiment, the first irradiation unit 10 irradiates the collection chamber 40c with the first irradiation light 12e via the light transmitting member 40g. According to this structure, the translucent member 40g can be provided between the space in which the first irradiation unit 10 is provided and the collection chamber 40c. For this reason, it is possible to suppress the entry of dead leaves or dead insect pests into the space, and to reduce the possibility that the function of the first irradiation unit 10 is impaired by dead leaves or the like.

  The light irradiation apparatus 100 according to the first embodiment includes a catalyst unit 26 including a photocatalyst 26b that generates carbon dioxide when irradiated with the first irradiation light 12e or the second irradiation light 24e. It is provided in the optical path of one irradiation light 12e. According to this configuration, since the catalyst unit 26 is provided in the optical path of the first irradiation light 12e, the first irradiation light 12e is efficiently applied to pests that are attracted to the periphery of the catalyst unit 26 by reacting with carbon dioxide. Can be irradiated.

  The light irradiation apparatus 100 according to the first embodiment includes a power generation unit 52 that outputs power, a storage battery 54 that stores at least a part of the power from the power generation unit 52, and the first irradiation unit 10 from the power generation unit 52 or the storage battery 54. A power supply unit 56 that supplies electric power. According to this configuration, since the power generation unit 52 is provided, the light irradiation device 100 can be used even in an area where the commercial power source cannot be used. Since the storage battery 54 is provided, the light irradiation device 100 can be used even in a time zone where power generation is not possible, such as at night.

[Second Embodiment]
With reference to FIG. 4, FIG. 5, the light irradiation apparatus 200 which concerns on 2nd Embodiment of this invention is demonstrated. FIG. 4 is a schematic diagram showing a cross-sectional view of the light irradiation apparatus 200 in a side view, and corresponds to FIG. FIG. 5 is a block diagram illustrating an example of the configuration of the light irradiation apparatus 200. The light irradiation apparatus 200 according to the second embodiment includes a container 42 for causing a pest to lay eggs with respect to the light irradiation apparatus 100 according to the first embodiment. While the light irradiation device 100 mainly irradiates the adult insects of the pests with the action light, the light irradiation device 200 mainly acts on the eggs laid by the pests, the larvae that hatched the eggs, and the pupae of the larvae It is comprised so that light may be irradiated.

  The light irradiation device 200 includes a first irradiation unit 210, an attracting unit 220, a control unit 230, a housing 40, a power supply unit 50, a communication unit 68, a failure detection unit 58, a timer 60, and an illuminance sensor. 62, a temperature sensor 64, a GPS sensor 66, a container 42, a storage tank 70, a rainwater collecting unit 72, a circulation unit 74, and a water level sensor 76 are mainly included. The casing 40, the power supply unit 50, the communication unit 68, the failure detection unit 58, the timer 60, the illuminance sensor 62, the temperature sensor 64, and the GPS sensor 66 have substantially the same characteristics as the light irradiation device 100 according to the first embodiment. Therefore, redundant explanation is omitted. Hereinafter, different configurations will be described.

(First irradiation unit)
In the light irradiation apparatus 200 according to the second embodiment, the first irradiation unit 210 is configured to irradiate the first irradiation light 212e mainly on the eggs laid by the pests, the larvae hatched by the eggs, and the pupae. Has been. In the example of FIG. 4, the 1st irradiation unit 210 is provided in the upper part of the collection chamber 40c so that the 1st irradiation light 212e may be irradiated downward. The first irradiation unit 210 may be arranged to output at least a part of the first irradiation light 212e to the collection chamber 40c of the housing 40. In the example of FIG. 4, the first irradiation unit 210 is arranged so that most of the first irradiation light 212e is output toward the collection chamber 40c.

  The 1st irradiation unit 210 is provided with the light source part 12 containing the light emitting element 12b similarly to 1st Embodiment. The light source unit 12 outputs the first irradiation light 212e having a wavelength characteristic that has an effect of reducing the reproductive function of the pest. Similar to the first irradiation light 12e of the first embodiment, the first irradiation light 212e includes medium wavelength ultraviolet rays (UVB / C waves) of 250 nm to 320 nm that have an effect of reducing the reproductive function of pests. The light having this wavelength characteristic also has an effect of reducing the reproductive function for insect eggs, larvae and pupae. The first irradiation light 212e is different in that the illuminance is lower than that in the first embodiment.

  That is, the egg N (c) laid in the container 42 is hatched to become a larva N (d), and emerges through the period of pupa N (e) until it becomes an adult N (f) 10-15. It is expected to remain in the container 42 for a period of days. In the meantime, since the first irradiation light 212e is irradiated, the cumulative exposure amount can be increased even if the illuminance is low. The illuminance of the first irradiation light 212e can be set by experiment according to a desired sterilization rate. As an example, the illuminance of the first irradiation light 212e may be set to 0.01 μW / square centimeter to 1 μW / square centimeter. In this case, the cumulative irradiation dose for 10 days is 8.64 mJ / square centimeter to 864 mJ / square centimeter. For example, when the desired cumulative dose is 6 mJ / square centimeter or more, the aforementioned cumulative dose range can satisfy the desired cumulative dose.

  Also in the second embodiment, the light source unit 12 may output light having a single wavelength characteristic or may output light having a plurality of wavelength characteristics. As the light emitting element 12b, an aluminum gallium nitride (AlGaN) LED can be used.

(Invitation Department)
The attracting unit 220 of the second embodiment includes the catalyst unit 26 and the second irradiation unit 22. The catalyst part 26 is the same as that of the first embodiment, and a description thereof will be omitted. In the example of FIG. 4, the 2nd irradiation unit 22 is attached to the side part of the collection chamber 40c.

(Control part)
The control unit 230 of the second embodiment differs from the control unit 30 of the first embodiment in that it includes a sixth acquisition unit, and the other configurations are the same. The sixth acquisition unit acquires the detection result from a water level sensor 76 described later.

(container)
The container 42 holds water 42b for allowing a pest such as a mosquito to lay eggs. The container 42 may be a water tank, for example. The container 42 is not particularly limited as long as a pest can enter and lay eggs. In the example of FIG. 4, the container 42 has a square hook shape with an open upper surface. The container 42 can be formed of various organic materials and inorganic materials according to desired specifications. In the example of FIG. 4, the container 42 is formed of a glass material from the viewpoint of weather resistance.

(Storage tank)
If the water 42b in the container 42 is not replenished for a long period of time, the water level will gradually evaporate and the water level will drop, and the eggs N (d), larvae N (d), etc. may be killed. Therefore, the light irradiation apparatus 200 according to the second embodiment includes a storage tank 70, a rainwater collection unit 72, and a circulation unit 74. The storage tank 70 stores spare water to be replenished in the container 42. The rainwater collecting unit 72 collects rainwater that rains on or around the light irradiation device 200 and sends it to the storage tank 70. That is, the storage tank 70 stores the collected rainwater in addition to the spare water. The circulation unit 74 circulates the water in the storage tank 70 with the water 42 b in the container 42. By configuring in this way, it is possible to mitigate a decrease in the water level of the container 42. The storage tank 70 is connected to the container 42 via a circulation unit 74. The circulation unit 74 can send water from the storage tank 70 to the container 42 when the water level of the water 42b in the container 42 decreases. The circulation unit 74 may supply the water 42b of the container 42 to the storage tank 70 when the water level of the water 42b of the container 42 rises excessively. A known water supply mechanism can be used as the circulation unit 74.

(Water level sensor)
When the water level of the water 42b in the container 42 is excessively lowered and becomes unsuitable for growth of larvae or the like, it is desirable to stop the operation of the first irradiation unit 210. Therefore, the light irradiation apparatus 200 according to the second embodiment is configured to stop the operation of the first irradiation unit 210 when the water level of the water 42b of the container 42 is excessively lowered. Specifically, a water level sensor 76 that detects the water level of the water 42 b in the container 42 and outputs the detection result to the control unit 230 is provided. Based on the detection result obtained from the water level sensor 76, the control unit 230 controls the operation of the first irradiation unit 210 and the second irradiation unit 22 to stop when the water level of the water 42b of the container 42 becomes lower than the threshold value. To do.

(Operation)
Next, an example of operation | movement of the light irradiation apparatus 200 comprised in this way is demonstrated. FIG. 6 is a flowchart for explaining an example of the operation of the light irradiation apparatus 200, and shows a process S200 related to this operation. The process S200 includes an operation of performing autonomous control according to the self-diagnosis and the detection result of each sensor after the light irradiation apparatus 200 starts the operation.

  As shown in FIG. 6, the process S200 is different from the process S100 of the first embodiment in that step S121 is added after N in step S120, and the other steps are the same. Therefore, the different parts will be described by omitting overlapping explanations.

  In the process S200, step S121 is added after N in step S120. In step S120, when the operation end time has not passed (N in step S120), the control unit 230 refers to the detection result of the water level sensor 76 and determines whether or not the water level of the water 42b in the container 42 is equal to or greater than the threshold value. (Step S121).

  When the water level is equal to or higher than the threshold (Y in Step S121), the control unit 230 returns the process to the beginning of Step S120 and repeats the processes from Step S120 to Step S121. When the water level is not equal to or higher than the threshold (N in Step S121), the control unit 230 shifts the process to Step S122, and ends the operations of the first irradiation unit 210 and the second irradiation unit 22 (Step S122). When the operation of the irradiation unit is completed, the control unit 230 transmits the three-dimensional position information and the operation end information to the management server on the wireless communication network via the communication unit 68 (step S124).

  If information is transmitted, the control part 230 will return a process to the head of step S102, and will repeat the process of step S102-step S124. The above-described process S200 is merely an example, and other steps may be added, some steps may be changed or deleted, and the order of steps may be changed.

  Next, in step S118, the action of the irradiation light of the first irradiation unit 210 and the second irradiation unit 22 will be described. When the second irradiation light 24e is irradiated to the outside, the pest N (a) is attracted around the light irradiation apparatus 200 in response to the irradiation light. At the same time, when the first irradiation light 212e is irradiated onto the photocatalyst 26b, the concentration of carbon dioxide around the photocatalyst 26b increases. The pest N (a) attracted to the periphery of the light irradiation device 200 reacts with the carbon dioxide concentration in the vicinity of the photocatalyst 26b and enters the inside of the collection chamber 40c.

  It is expected that the pest N (b) that has entered the collection chamber 40c drifts in the vicinity of the catalyst unit 26 and lays eggs N (c) near the water surface of the water 42b in the container 42. Egg N (c) will eventually hatch and become larva N (d). Larva N (d) eventually becomes pupa N (e). The pupa N (e) eventually emerges to become an adult N (f) and exits the collection chamber 40c. During this period of about 10 to 15 days, eggs N (c), larvae N (d) and pupa N (e) are irradiated with the first irradiation light 212e, which causes them to lose fertility and become infertile. Go.

  The infertile adult N (g) that has left the collection chamber 40c returns to nature and performs breeding activities with normal individuals, but the next generation of pests will not be born, and the breeding opportunities for other individuals will be reduced. As a result, the generation of next-generation pests is suppressed as a whole. It can be expected that the pests are gradually reduced by repeating such an operation for a long time.

  Next, operations and effects of the light irradiation apparatus 200 according to the second embodiment will be described.

  The light irradiation apparatus 200 according to the second embodiment is a light irradiation apparatus for irradiating at least one of a pest egg, a pest larva and a pest puppet, and a container 42 for causing the pest to lay eggs. And a first irradiation unit 210 that irradiates the container 42 with a first irradiation light 212e including light having a wavelength characteristic capable of sterilizing at least one of a pest egg, a pest larva and a pest pupa. According to this configuration, the infertile adult can be efficiently born and returned to the natural world, and the propagation of the pest can be suppressed. Even if the illuminance of the first irradiation light 212e is lowered, an effect is produced. Therefore, the power supplied to the power supply unit 50 can be small, and the power supply unit 50 can be easily downsized. The first irradiation unit 210 can be reduced in size because low illumination is sufficient.

  The light irradiation apparatus 200 according to the second embodiment includes a second irradiation unit 22 that outputs second irradiation light 24e having a wavelength characteristic capable of attracting pests. According to this configuration, it is possible to attract pests located away from the light irradiation device 200 to the periphery of the light irradiation device 200.
