Description

Technology Field

[0001] The present invention relates to a laser-based pest defense system using a scanning mirror. Background Technology

[0002] Pest damage poses a serious problem for farms and livestock barns. Pests threaten the health of livestock, spread diseases, and reduce productivity. In particular, pests such as mosquitoes, flies, and mites can suck the blood of livestock or transmit pathogens that cause infection. Existing pest control methods include the use of insecticides, the installation of insect screens, and electric pest repellents, but these methods have limitations. Insecticides can cause environmental pollution and resistance issues, while insect screens are difficult to maintain and can restrict space utilization. Electric pest repellents are effective only when pests make direct contact, resulting in an ambiguous and limited range of protection.

[0003] These pest problems cause inconvenience in daily life not only in farms and livestock barns but also in ordinary households. Mosquitoes and flies cause hygiene issues, and especially during the summer, pests easily enter indoors when windows are opened for ventilation. Insect screens obstruct the flow of air entering through windows, and over long-term use, dust accumulates, making maintenance difficult.

[0004] To address these issues, laser-based pest control technology is gaining attention. Laser technology can be used to defend specific areas while maintaining open spaces. Furthermore, by setting appropriate laser output and frequency or utilizing sensors that detect human movement, pest control effects can be maintained while remaining harmless to humans and livestock.

[0005] For example, there is a method that prevents pests from entering by installing multiple laser modules at regular intervals on the window frame and emitting laser beams. However, this method is unreliable in blocking pests due to the spacing between lasers and the emission of lasers with insufficient lethality. Additionally, increasing the laser output leads to the problem of higher costs resulting from the use of multiple lasers.

[0006] Another example is a method that uses laser reflectors and detection sensors to detect and eliminate pests invading through windows. However, this reflection method has problems in that it is uncertain to achieve insecticidal effects across the entire window and is difficult to apply in outdoor environments without window frames. The problem to be solved

[0007] Existing pest control methods, such as insecticides, insect screens, and electric pest repellents, have limitations including environmental pollution, the development of resistance, and effectiveness. In particular, they face limitations in effectively blocking the entry of pests in open spaces, and this invention aims to address these issues.

[0008] Furthermore, existing laser-based pest control technologies suffer from problems such as incomplete pest blocking due to the use of low-power lasers with insufficient lethality, or high costs resulting from the need for multiple laser elements; this invention aims to resolve these issues.

[0009] In addition, existing laser methods are limited to application only to specific structures such as windows, making them difficult to utilize in open environments; this invention aims to resolve this limitation. means of solving the problem

[0010] The present invention relates to a pest defense system using a laser, comprising: a frame; a first laser unit for emitting a first laser; and a scanning mirror for rotating; wherein the scanning mirror is positioned to reflect the emitted first laser and configured to irradiate the reflected first laser onto at least a portion of the inner perimeter of the frame.

[0011] Additionally, the frame further includes a frame scanning mirror inside, and the frame scanning mirror is configured to reflect the irradiated first laser back.

[0012] Additionally, it further includes a second laser unit for emitting a second laser, wherein the second laser unit is positioned so that the scanning mirror reflects the emitted second laser.

[0013] Additionally, the frame is positioned vertically or horizontally with respect to the ground and further includes a sensor positioned at the top of the frame; and when the sensor detects a pre-designated target, the first laser emission is stopped.

[0014] In addition, the frame is made of at least one of metal, stainless steel, aluminum, aluminum alloy, high-strength plastic, and carbon fiber composite.

[0015] In addition, the scanning mirror is configured to rotate at a speed of 20 to 60 times per second.

[0016] In addition, the first laser unit is configured such that the first laser has a power of 5W-100W, and the second laser unit is configured to emit a UV-C laser.

[0017] The present invention relates to a laser-based pest defense system comprising a laser emission assembly, wherein the laser emission assembly comprises a first laser unit for emitting a first laser in a first direction, a second laser unit for emitting a second laser in a second direction, a third laser unit for emitting a third laser in a third direction, and first to third scanning mirrors for rotating, wherein the first scanning mirror is configured to reflect the emitted first laser in a first range, the second scanning mirror is configured to reflect the emitted second laser in a second range, and the third scanning mirror is configured to reflect the emitted third laser in a third range.

[0018] Additionally, it further includes a support column positioned vertically with respect to the ground; a base plate positioned on the support column; and a cover plate; wherein the laser emitting assembly is positioned between the base plate and the cover plate.

[0019] Additionally, it further includes a solar panel for converting sunlight into electrical energy; and a battery for storing said electrical energy; wherein the solar panel is placed on the cover plate. Effects of the invention

[0020] According to the present invention, pests can be directly removed using a high-power laser, and effective pest control is possible in open spaces.

[0021] In addition, by providing a frame-based blocking method and an open multi-laser placement method, it can be applied not only to windows but also to various environments such as livestock barns, farmlands, and food processing plants.

[0022] In addition, independent power supply utilizing solar power and batteries is possible, and the safety of people and livestock can be ensured through laser control using sensors. Brief explanation of the drawing

[0024] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings. Identical or similar components are given the same reference number regardless of the drawing symbols, and redundant descriptions thereof will be omitted.

[0025] In addition, when describing the embodiments disclosed in this specification, if it is determined that a detailed description of related prior art may obscure the essence of the embodiments disclosed in this specification, such detailed description is omitted. Furthermore, the attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and the technical concept disclosed in this specification is not limited by the attached drawings; it should be understood that the drawings include all modifications, equivalents, and substitutions that fall within the spirit and technical scope of the invention.

[0026] <Fig. 1>

[0027] FIG. 1 shows a schematic structure of a laser-based pest defense system according to one embodiment of the present invention. As an overall operation of the system, a laser unit (100) emits a beam that blocks pests, and a collimator lens (110) can precisely adjust the emitted beam. At this time, a scanning mirror (200) can be driven by a DC motor (210) and distributes the laser beam over a wide area while rotating repeatedly. In addition, the present invention may include a frame (300) and a power control board (400) responsible for power and control. Now, details of each component will be described below.

[0028] First, the laser unit (100) according to one embodiment of the present invention emits a high-power laser for removing pests. The laser used in the present invention can be implemented in various ways, and representative examples include semiconductor lasers, solid-state lasers, and CO₂ lasers. Semiconductor lasers have high power efficiency at relatively low power, but at high power, thermal management and reinforcement of the focusing lens are generally required. Therefore, while they are advantageous for removing small pests at low power, additional optical design may be required to effectively remove medium-sized or larger pests. Solid-state lasers can be implemented based on Nd:YAG (neodymium-yttrium-aluminum-garnet) and can maintain a stable beam even at high power, making them suitable for effectively removing medium-sized or larger pests. CO₂ lasers emit strong thermal energy, enabling immediate killing, but problems related to cost and space may arise due to their large size and the need for a cooling system. Additionally, the laser unit (100) can be implemented in various ways to achieve the technical effects of the present invention.

[0029] Meanwhile, the laser unit (100) has a specific output range for effectively eliminating pests. For example, the laser output can be adjusted within a range of 5W to 100W, and the killing power varies depending on the output range. Specifically, an output of 5W to 30W is effective mainly against small pests such as mosquitoes or fruit flies. An output of 30W to 60W is effective mainly against medium-sized pests such as flies or moths, and can kill them even with a short irradiation time. An output of 60W to 100W can eliminate relatively large pests such as wasps and cockroaches, and can incapacitate them immediately by rapidly evaporating the moisture in the pests' bodies even with a short laser irradiation time. At an output of 100W or more, strong thermal energy can be emitted to effectively eliminate not only pests but also small rodents. However, it is necessary to determine the power range by considering factors such as preventing unnecessary energy consumption, ensuring the safety of the device, and the price.

[0030] In addition, the wavelength of the laser unit (100) can generally be adjusted between 200 nm and 1100 nm, and each wavelength exhibits different effects depending on the physiological response and absorption rate of the pest. In particular, a blue laser in the range of 400 nm to 600 nm can be evaluated as a suitable wavelength for the present invention. A blue laser with a short wavelength has a high absorption rate within the body of the pest, making it possible to block pests even at relatively low output. Furthermore, while the blue laser belongs to the visible light region, it generates less heat than an infrared laser (700 nm or higher), thereby minimizing the impact on the surrounding environment. As such, the blue laser can achieve high pest removal efficiency with relatively low energy consumption and is suitable for implementing a safe defense system.

[0031] Additionally, the laser unit (100) is positioned on a frame (300) that is positioned vertically to the ground, so that it can emit a beam parallel to the ground. This is an advantageous method for ensuring safety by preventing unnecessary contact between the laser unit (100) and humans and livestock. Specifically, by positioning the laser unit (100) on the frame (300), it can be protected from contaminants such as dust, allowing it to operate stably for a long period of time and reducing the risk of malfunction caused by external impact.

[0032] However, in the present invention, the laser unit (100) does not necessarily need to be placed on top of the frame (300). For example, the purpose of the present invention can be sufficiently achieved even if the laser unit (100) is placed on the side or bottom of the frame (300), and the effect of such a difference in placement method on the technical effect of pest defense is minimal. That is, the placement method of the laser unit (100) can be changed depending on the structural characteristics of the device or the installation environment, and does not impede the essential effect of the present invention.

[0033] A collimator lens (110) according to one embodiment of the present invention is an optical component that performs the function of precisely adjusting the beam of a laser unit (100). Generally, light emitted from a laser has the characteristic of spreading as it travels a certain distance. A spread laser may not be able to deliver sufficient energy to a target. Therefore, the collimator lens (110) adjusts the light emitted from the laser unit (100) to be parallel, and pests can be blocked more effectively.

[0034] The collimator lens (110) can be positioned in a straight line with the laser unit (100). That is, the beam passes through the collimator lens (110) located in front of the light-emitting part (not shown) of the laser unit (100), and the beam can be aligned. At this time, the distance between the collimator lens (110) and the laser unit (100) can be adjusted to the focal length, thereby allowing the beam passing through the collimator lens (110) to be maintained in a constant shape.

[0035] The collimator lens (110) can generally be composed of a single lens or an array of multiple lenses. In the case of a single lens, the collimator lens (110) converges light that diffuses in a conical shape to maintain a constant beam width. In the case where an array of multiple lenses is applied, the collimator lens (110) can adjust the beam's diffusion angle more precisely by adjusting the focal length and optical axis alignment, and can maintain stable beam quality even over long distances.

[0036] A scanning mirror (200) according to one embodiment of the present invention is an optical component that converts a laser beam emitted from a laser unit (100) into a surface shape. That is, the laser beam is basically emitted in the form of a single line, but can cover a wide area by means of a rapidly rotating scanning mirror (200). Specifically, the laser beam reflected by the rotating scanning mirror (200) can be irradiated onto at least a portion of the inner perimeter of the frame (300). As a result, the continuously formed surface-shaped laser beam blocks and eliminates pests passing through a certain area.

[0037] The scanning mirror (200) rotates at a constant speed by a DC motor (210), and, for example, can rotate 20 to 60 times per second. As a result, the laser beam irradiated onto the scanning mirror (200) is transformed from a simple line shape into a shape that covers a certain area.

[0038] To maintain accurate beam reflection due to high-speed rotation, the scanning mirror (200) may be made of a reflective coating material with high surface precision. Generally, an aluminum or silicon-based reflective scanning mirror may be used, and a gold (Au) or silver (Ag) coating may be applied to the surface of the scanning mirror (200) to maximize laser reflectivity. Through this, the loss of laser energy can be reduced and the reflection angle can be maintained stably.

[0039] Meanwhile, the scanning mirror (200) rotates to reflect the laser within a certain rotation range, namely the first angle (S1). The first angle (S1) may be 112°–120°, but this is not an absolute value and can be adjusted according to the size of the frame (300) and the design of the system. For example, a rotation range of 150° or more may be applied to cover a wide area. Conversely, when operating in a narrow space, the first angle (S1) may be adjusted to 90° or less to prevent beam diffusion into unnecessary areas. However, due to the arrangement structure of the laser unit (100) and the scanning mirror (200), it is inappropriate for the first angle (S1) to be 180° or more. If the first angle (S1) is configured to exceed 180°, the laser beam may not be reflected normally, or the achievement of the insecticidal effect in a specific range becomes uncertain.

[0040] Additionally, the scanning mirror (200) can be positioned at the top of the frame (300) opposite the laser unit (100). That is, the laser unit (100) is fixed at one end of the top of the vertically positioned frame (300), and the scanning mirror (200) can be positioned at the opposite end of the top of the frame (300).

[0041] However, the above arrangement is merely an example, and the scanning mirror (200) does not necessarily need to be fixed in a specific position. In the present invention, the role of the scanning mirror (200) is to reflect a laser beam while rotating within a first angle (S1) and to form a laser surface inside the frame (300), so various arrangements are possible as long as they are in a position that can effectively cover the entire area of ​​the frame (300).

[0042] A DC motor (210) according to one embodiment of the present invention rotates the scanning mirror (200) at a constant speed and operates by receiving power from a power control board (400). In the present invention, since the scanning mirror (200) must rotate 20 to 60 times per second to reflect the laser beam in a constant pattern, a brushless DC motor (BLDC) or a stepper motor capable of precise speed control may be applied. Through this, the laser beam can be formed into a uniform surface.

[0043] A frame (300) according to one embodiment of the present invention is a structure that serves as a standard for determining the pest control range. That is, the frame (300) limits the radiation range of the laser beam to prevent unnecessary radiation and energy loss, and enables the pest removal effect to be maximized. In addition, the frame (300) can perform the role of supporting and protecting components such as the laser unit (100), collimator lens (110), scanning mirror (200), and DC motor (210).

[0044] The frame (300) can prevent dangerous situations such as fire. For example, it is necessary to control the laser beam so that it is not irradiated onto unnecessary objects. To this end, the frame (300) may include a shielding structure so that the laser beam is emitted only within a designated path, and a heat dissipation design to prevent overheating may be applied.

[0045] Metal, stainless steel, aluminum, high-strength plastic, carbon fiber composite, etc., may be considered as materials for the frame (300), and among them, aluminum may be adopted as one of the suitable materials. Aluminum has excellent lightness and high strength, and excellent heat dissipation, so it can maintain stability even in systems that operate for a long time. In addition, since aluminum is highly durable and resistant to corrosion, its performance can be maintained even in long-term usage environments. If necessary, coated aluminum alloy or composite material may be used to enhance heat resistance and shielding functions in specific environments.

[0046] Meanwhile, the frame (300) may have a U-shaped form, with the closed part facing the ground and installed vertically to the ground. However, there are no special restrictions on the shape and arrangement method of the frame (300), and it may be changed depending on the installation environment. That is, depending on the situation, an open or closed structure may be selected, and a polygonal shape may be adopted. In addition, an inclined arrangement may be appropriate in certain environments.

[0047] The frame (300) may, in some cases, be manufactured integrally with at least one of the laser unit (100), collimator lens (110), scanning mirror (200), and DC motor (210). This allows for increased structural stability of the pest defense system while simplifying the assembly process and facilitating maintenance of the device.

[0048] A power control board (400) according to one embodiment of the present invention can supply and control stable power to key components of the present invention, such as a laser unit (100) and a DC motor (210). Specifically, the power control board (400) adjusts the voltage and current according to the power requirements of each component, and this is based on the DC power supplied by the SMPS (410). In addition, the power control board (400) may include power cutoff and protection functions as needed.

[0049] An SMPS (410) according to one embodiment of the present invention is a switching mode power supply that converts alternating current (AC) power into direct current (DC) power and supplies it to a power control board (400). The SMPS (410) enables high-efficiency power conversion, generates little heat, and is easy to lighten, thereby supporting the stable operation of the power system of the present invention.

[0050] <Fig. 2>

[0051] FIG. 2 is a cross-sectional view of a laser-based pest defense system according to one embodiment of the present invention. In this embodiment, it can be seen that a single laser emits a beam. Additionally, a frame scanning mirror (310) may be included inside the frame (300).

[0052] A frame scanning mirror (310) according to one embodiment of the present invention can maximize the insecticidal effect by re-reflecting the laser beam reflected by the scanning mirror (200). In particular, the laser beam re-reflected from the frame scanning mirror (310) can effectively act on pests that move mainly along the ground. If only the frame (300) exists, the laser beam may be absorbed or scattered on the surface of the frame (300), reducing its utility. However, by including the frame scanning mirror (310), the laser beam can be reused more efficiently.

[0053] Meanwhile, when the frame scanning mirror (310) is installed on the frame (300) of the ground portion, people or livestock may step on the frame scanning mirror (310), so durability needs to be considered. To this end, durability can be enhanced by applying a material resistant to impact and friction to the frame scanning mirror (310) or by adding a protective layer.

[0054] Additionally, the frame scanning mirror (310) can be manufactured from a material that maintains high reflectivity while considering cost-effectiveness. Scanning mirrors with gold (Au) or silver (Ag) coatings have excellent reflectivity but have the disadvantage of high cost. Accordingly, aluminum (Al) coated scanning mirrors, copper (Cu)-based scanning mirrors, or multilayer dielectric coated scanning mirrors may be considered. Aluminum coated scanning mirrors are widely used in industrial laser systems because they have excellent reflectivity while having low manufacturing costs. Copper-based scanning mirrors are highly durable and can be used stably even with high-power lasers. Multilayer dielectric coated scanning mirrors can be designed to have high reflectivity at specific wavelengths, allowing for optimization tailored to the laser wavelength of the present invention.

[0055] <Fig. 3>

[0056] FIG. 3 is a cross-sectional view of a laser-based pest defense system using dual lasers according to an embodiment of the present invention.

[0057] In this embodiment, two independent laser sections (100a, 100b) may be included. Each laser section (100a, 100b) can individually form a laser surface, and accordingly, the pest blocking effect may be improved.

[0058] For example, the first laser unit (100a) and the second laser unit (100b) may emit lasers at different angles. In this case, separate laser surfaces may be formed as each laser beam is irradiated and reflected by the scanning mirror (200). Additionally, even when the two laser units (100a, 100b) emit beams at the same angle, each laser beam may be irradiated by a separate scanning mirror (200) having a different rotation speed. That is, the laser surfaces generated based on each laser unit (100a, 100b) may have different patterns, thereby effectively preventing the intrusion of pests.

[0059] Meanwhile, as another embodiment, a UV-C (254nm) laser may be applied to the first laser unit (100a) and operated in parallel with the second laser unit (100b). Since the UV-C laser can damage the DNA and RNA of viruses or microorganisms in the air, it may contribute to reducing airborne infectious agents. At this time, since the UV-C laser may not be effective for blocking pests, the second laser unit (100b) having an output of 5W-100W and the first laser unit (100a) to which the UV-C laser is applied may be operated in parallel.

[0060] <Fig. 4>

[0061] FIG. 4 is a cross-sectional view of a laser-based pest defense system to which a sensor according to an embodiment of the present invention is applied. The sensor (120a, 120b) may be implemented as a lidar, optical, infrared, ultrasonic sensor, etc. When the sensor (120a, 120b) detects a designated target, such as a human or livestock approaching from inside or outside, it may notify the power control board (400) or the laser unit (100) with a detection signal. Upon receiving the detection signal, the power control board (400) may cut off the power to the laser unit (100), or the laser unit (100) may stop emitting the laser on its own upon receiving the detection signal. Additionally, the sensor (120a, 120b) does not need to be installed in all grid frames, but may be installed only in some grid frames that are frequently passed through by humans or livestock. Consequently, according to an embodiment of the present invention, safety for humans and livestock can be ensured while maintaining the pest defense effect.

[0062] <Fig. 5>

[0063] FIG. 5 is a drawing showing an example of a laser-based pest defense system applied according to one embodiment of the invention. The system of the present invention can be installed in an open space such as a building window or a grid structure (fence) of a livestock barn.

[0064] In open spaces such as livestock barns, there is a high influx of pests; however, according to the present invention, pests can be blocked without physical barriers, thereby reducing stress on livestock and the spread of diseases caused by pests. In particular, in environments such as livestock barns, blocking pests while maintaining airflow is a crucial factor in livestock health and hygiene management.

[0065] In addition, in a livestock barn environment, a sensor (120) can be applied to an internal area to protect livestock, so that laser emission is automatically blocked when livestock approaching the laser is detected. On the other hand, sensors can be placed only in specific areas where people enter and exit the barn. As a result, an optimal system can be implemented that considers the safety of livestock and people while maintaining the pest-blocking effect.

[0066] <Fig. 6>

[0067] FIG. 6 is a diagram showing a plurality of laser units emitting lasers in different directions. In this embodiment, the first laser unit (101), the second laser unit (102), and the third laser unit (103) each emit lasers in different directions, and as a result, laser planes of the first region (A1), the second region (A2), and the third region (A3) can be formed, respectively. An assembly of each laser unit (101, 102, 103), scanning mirrors (201, 202, 203), and power control board (400) can be defined as a laser emission assembly.

[0068] For example, when the second laser unit (102) emits a laser beam, the laser beam is irradiated onto the second scanning mirror (202) which rotates within the range of the second angle (S2), and a second region (A2) is formed by the reflected laser beam. Similarly, a first region (A1) is formed by the first laser unit (101) and the first scanning mirror (201), and a third region (A3) is formed by the third laser unit (103) and the third scanning mirror (203). In the parts where overlap occurs between regions, the laser is reinforced, and the pest blocking effect can be further strengthened.

[0069] Next, the first area (A1), the second area (A2), and the third area (A3) are integrated to form a laser shield area overall. Here, the laser shield area refers to an area within the range where laser beams emitted from each laser unit (101, 102, 103) are irradiated, which maintains an intensity capable of neutralizing or eliminating pests. The laser shield area may increase or decrease depending on the output intensity of the laser.

[0070] Specifically, the first laser unit (101) can emit a first laser in a first direction. At this time, the first scanning mirror (201) can reflect the emitted first laser in a first range having a second angle (S2), and a laser surface of the first region (A1) is formed. Subsequently, the second laser unit (102) can emit a second laser in a second direction. The second scanning mirror (202) can reflect the emitted second laser in a second range having a second angle (S2), and a laser surface of the second region (A2) is formed. Then, the third laser unit (103) can emit a third laser in a third direction. The third scanning mirror (203) can reflect the emitted third laser in a third range having a second angle (S2), and a laser surface of the third region (A3) is formed.

[0071] Meanwhile, the second angle (S2) may be 158° as one example. However, due to the arrangement structure of each laser unit (101, 102, 103) and scanning mirror (201, 202, 203), it is inappropriate for the second angle (S2) to be 180° or more. If the second angle (S2) is configured to exceed 180°, the laser beam may not be reflected normally, or the achievement of the insecticidal effect within a specific range becomes uncertain.

[0072] In addition, the power control board (400) distributes power to each laser unit (101, 102, 103) and scanning mirror (201, 202, 203) and controls the operating state of each laser unit to enable efficient use of energy.

[0073] In summary, in this embodiment, a blocking area can be formed without a frame (300), so a pest blocking effect can be expected even in spaces where it is difficult to install structures or in large areas.

[0074] <Fig. 7>

[0075] FIG. 7 is a drawing showing an open pest defense system (1000) according to one embodiment of the present invention. This embodiment may include a support column (500), a base plate (510), a cover plate (520), and a laser emission assembly.

[0076] A support column (500) according to one embodiment of the present invention supports the entire structure by fixing the open pest defense system (1000) to the ground. AC power can supply power to the laser emission assembly through the support column (500). The support column (500) can be designed to be height-adjustable.

[0077] A base plate (510) according to one embodiment of the present invention is placed on top of a support column (500). That is, the base plate (510) supports the laser emission assembly to stably emit a laser beam, while simultaneously protecting internal electronic components and optical elements.

[0078] A cover plate (520) according to one embodiment of the present invention is placed over a laser emission assembly and protects the laser component from the external environment. In particular, the cover plate (520) is configured to protect the internal component from rain, dust, and other external elements.

[0079] A laser emission assembly may be disposed between the base plate (510) and the cover plate (520). The laser emission assembly may include the same components as described in FIG. 6. That is, a laser shield area is formed by a laser emission assembly comprising at least one laser unit, at least one scanning mirror, and a power control board.

[0080] <Fig. 8>

[0081] FIG. 8 is a drawing showing another example of an open pest defense system (1000) according to one embodiment of the present invention. This embodiment is characterized by supplying power using solar energy, so that it can be operated independently even in areas with insufficient power infrastructure.

[0082] A solar panel (420) according to one embodiment of the present invention converts solar energy into electrical energy and can be placed on a cover plate (520). The solar panel (420) can generate electricity using solar energy during the day, thereby allowing the system to operate autonomously without an external power grid. Additionally, the solar panel (420) may be installed in a fixed position, but it can be designed to allow for angle adjustment as needed and can be adjusted to enable optimal solar energy collection depending on the installation environment.

[0083] A battery (430) according to one embodiment of the present invention stores electrical energy generated from a solar panel (420). The battery (430) may be placed at the bottom of a support column (500) or near the ground, but there are no special restrictions on its location. The battery (430) stably supplies power even at night or in cloudy weather when sunlight is insufficient, so that the system can operate continuously.

[0084] <Fig. 9>

[0085] FIG. 9 is a drawing showing an example in which multiple open pest defense systems (1000a, 1000b, 1000c...) are arranged according to one embodiment of the present invention. This embodiment shows an arrangement designed to perform pest defense in large open spaces such as farmland, orchards, and forest areas. Each open pest defense system (1000) is placed above the ground via a support column (500) of a certain height, and a laser emitting assembly is mounted on the top thereof to block pests in a specific area.

[0086] Specifically, a number of open pest defense systems (1000a, 1000b, 1000c...) can be arranged at regular intervals, and each system can form a blocking area (Laser Shield Area) individually while being arranged in an overlapping manner to effectively cover a large area.

[0087] For example, the distance between each system can be set to 6 to 12 meters. This distance is a value adjusted so that the blocking areas of each open pest defense system (1000) overlap, while preventing adverse effects on adjacent systems. Additionally, the spacing between systems can be adjusted according to terrain or pest density.

[0088] Embodiments of the present invention can be applied in various environments. For example, the present embodiment can be applied in spaces such as farmland, orchards, forest protection areas, gardens, and large parks that protect crops. Each open pest defense system (1000) can be operated independently, and if necessary, multiple systems may be networked and coordinated from a central control unit. In this case, if the pest incidence rate in a specific area increases, it is possible to respond by activating the system in that area or increasing the output. Explanation of the symbols
