Description

Technology Field

[0001] The present invention relates to a target. The present invention relates to a method for manufacturing a target. Background Technology

[0002] Shooting and archery are expanding beyond military purposes to include self-defense, leisure, and sports. A target refers to the object used for aiming in shooting or archery. Such targets are required not only during the day but also at night. To utilize targets at night, infrared targets that emit heat are provided. These infrared targets can be easily detected by thermal imaging sights. Since these thermal imaging sights create images by detecting the thermal energy (infrared) of objects, they can detect targets even in complete darkness.

[0003] Examples of inventions regarding the above-mentioned infrared target include cited inventions 1, 2, and 3.

[0004] Cited invention 1 provides a heating element in the central part, but the range of infrared radiation provided is narrow. There is a problem that it is expensive to provide a wide infrared target. In particular, to provide a heating element, wires (30), threads (32), and heating paint (20) are provided. However, this technology is not realistic in terms of the difficulty of connecting the heating paint and the wires, the manufacturing method, and the manufacturing cost. In addition, there is a problem that it cannot be used in rainy weather due to the risk of electrical leakage.

[0005] Cited invention 2 provides a thermal film layer (102) in the central portion. The thermal film layer (102) utilizes radiant heat from a film with low emissivity (less than 25% in identification number 102, etc.). Accordingly, there are problems with weak infrared radiant heat and the inability to use it for a long period. To explain in detail, energy incident on an object can be reflected, absorbed, and transmitted. Among these, the absorbed energy can be radiated as radiant heat. Meanwhile, radiant heat can be governed by the Stefan-Boltzmann law. Accordingly, the thermal radiation performance is eventually lost after a certain period of time. Accordingly, a large energy storage layer must be provided on the target. Nevertheless, the radiation performance is eventually lost. In addition, there is a problem that the desired infrared performance cannot be sustained because the temperature gradually decreases.

[0006] Cited Invention 3 irradiates an image onto a target using a laser light source (2). Cited Invention 3 allows the image to function as a target. The above method may have a prominent advantage in that the target can be shaped into a specific form. However, it is excessively difficult to provide a two-dimensional infrared shape of the target using a point light source. This is because it is difficult to transmit energy equivalent to that emitted by infrared rays from the target. Accordingly, Cited Invention 3 cannot be practically applied in real life.

[0062] <1st Embodiment>

[0063] [Composition of the Target]

[0064] FIG. 1 is a plan view (a) and a schematic exploded perspective view (b) disclosing a target according to a first embodiment. Refer to FIG. 1. The first embodiment may be suitable for a target at a distance.

[0065] The target (T) of the present disclosure may include a recognition area (1). The recognition area may refer to a part that is recognized more prominently than other areas. The recognition area may include an area where infrared radiation is emitted. The recognition area may be placed on a predetermined plane. The recognition area may emit infrared radiation in the normal direction of the plane. The radiant heat of the recognition area may be recognized more prominently than other areas by the thermal imaging sight. The recognition area may have a predetermined shape. Here, the shape may include a two-dimensional shape provided on the plane. Here, the shape may be provided by a heating element having a predetermined width changing its direction of extension. Here, the inner area of ​​the shape may provide a target area (2). To this end, the heating element may be a planar heating element. The target area (2) may be provided adjacent to the interior of the shape. That is, the target area (2) may be located adjacent to the interior of the shape compared to the exterior of the shape. Here, the shape may have a geometric center by maintaining a contracting shape. Accordingly, the observer can intuitively perceive that the target is located at the geometric center of the shape. Consequently, according to the target of the present disclosure, the observer's visibility can be greatly enhanced.

[0066] The target area (2) may be provided by the recognition area (1). The target may be an area that requires focused observation. The target area may be an area intended for hitting. For example, it may be an area where a bullet or arrow must hit. The heating element may be assumed to change its direction of extension and to connect a virtual line connecting the heating element and both ends of the heating element. As a result, the interior of the recognition area may provide a two-dimensional interior area separated from the exterior. Here, the two-dimensional interior area may be the target area. The target area (2) may be provided inside the boundary of the recognition area. A non-target area (3) may be provided outside the boundary of the recognition area.

[0067] The above non-target area (3) may be an area that is not a target. The above non-target area may be an area that occurs incidentally, necessarily, or accidentally to provide the target (T). For example, it may be an area where a bullet or arrow is judged to have missed. The above non-target area may not be provided. For example, the recognition area may extend to the edge of the target (T). In this case, the non-target area is not provided.

[0068] The above recognition area, the above target area, and the above non-target area may each be named the above recognition module, the above target module, and the above non-target module. However, the primary view of the target (T) in the present disclosure is that it is observed from the first direction from the perspective of an observer (including an unmanned aerial vehicle, a camera, and a robot). Accordingly, it is defined as each area indicated on the first slope to enhance convenience of understanding.

[0069] The relationship between the above recognition area, the above target area, and the above non-target area is clearly explained.

[0070] In the representation of the above recognition area, the above target area, and the above non-target area, the area may refer to an area defined on a slope perpendicular to a first direction (e.g., the +x axis). The recognition area may be placed on the first slope perpendicular to the first direction. The recognition area may be extended with a predetermined width. Here, the width may be provided to be at least 10 times greater than the thickness. Here, the width may refer to the thickness direction perpendicular to the extension direction of the recognition area within the first slope. Here, the thickness may refer to the thickness of the recognition area in the first direction. The recognition area may have a first part extending in a second direction within the first slope, and a second part extending in a third direction within the first slope. The first part and the second part may be continuous. One end of the first part and one end of the second part may be in contact with each other. The other end of the first part and the other end of the second part may be spaced apart from each other.

[0071] The above recognition area (1) may be heated by electricity to emit a first light (e.g., infrared). Electricity may flow directly through the above recognition area. Since electricity flows directly in this way, it is desirable that the above recognition area is not hit by a bullet. If a bullet hits the above recognition area, it can be determined that it did not hit. The above recognition area may only be used to recognize that the above target area is inside it.

[0072] The target area may be provided in the inner area of ​​the first slope, which is provided by a virtual line connecting the recognition area and both ends of the recognition area. The virtual line may be provided as a single unit. The recognition area may be one unit, and the virtual line may also be one unit. Accordingly, if the recognition area is the planar heating element (10), it may be provided as a single unit. This will be described later. The inner area may be provided in at least one of the first slope in the same direction as the first slope, and the second slope having a predetermined distance from the first slope in the first direction. In other words, the inner area may refer to an area that is differentiated from the recognition area in response to observation in the first direction. Even if the first slope and the second slope have a predetermined distance in the first direction, the distance may be provided sufficiently small. Through this, when an observer observes from the first direction, the recognition area and the target area can be distinguished. That is, even if the first slope and the second slope are separated by a predetermined distance in the first direction, if the recognition area and the target area are distinguished in response to observation in the first direction, the first slope and the second slope can be defined as the same slope. In this case, the first slope and the second slope can be considered the same plane from an engineering perspective. However, depending on the embodiment, there may be cases where they cannot be considered the same plane from an engineering perspective. In such cases, the embodiment will be explained separately.

[0073] The above target area (2) may be an area where a bullet must hit. The geometric center of the above target area may be the most desirable priority target area. The above target area may further be provided with a shape that displays the priority target area in a hierarchical manner. The above target area may emit light (energy) of a different form than the recognition area. The above target area may not be provided with a separate structure for infrared radiation. Visible light may be reflected or emitted from the above target area.

[0074] The above non-target area (3) may be placed outside the target area (2) with the recognition area (1) as the boundary. The above non-target area may be an area where attention should not be focused. The above non-target area may be an area where it is not desirable to hit. The above non-target area may be an area where it should not be hit.

[0075] The above target (T) may include a planar heating element (10). The above recognition area (1) may include the planar heating element. An observer can recognize the recognition area (1) by means of heat generated by electricity from the planar heating element. The planar heating element has a predetermined thickness in the first direction, but can be provided with a width at least twice, preferably at least ten times, in the first slope. For this reason, it can be referred to as a planar (slope-shaped) heating element. As previously explained, the recognition area (1) extends from the first slope in the second direction and the third direction and can have a predetermined width. Accordingly, visibility of the recognition area (1) can be provided to the observer. The planar heating element may be provided in a shape having a small upper part and a large lower part based on the drawing. For example, the small upper part may be the head, and the large lower part may be the torso. The shape that the above-mentioned planar heating element can provide on the first slope may vary.

[0076] Electrodes (10a) may be provided at both ends of the above-mentioned planar heating element (10). Power may be supplied to the above-mentioned planar heating element through the electrodes. The above-mentioned planar heating element may generate heat by the supplied power. The electrodes may be made of brass and copper foil. A temperature sensor (16) may be provided adjacent to the electrodes. The temperature measured by the temperature sensor (16) may be fed back to the control unit (14). The control unit (14) may detect the temperature and control it to a target temperature. The temperature may correspond to the degree detected by a thermal imaging sight. For example, it may be considered that the higher the temperature, the stronger the infrared radiation emitted, making it more prominent in the thermal imaging sight. For example, if the temperature detected by the control unit is low, the power may be controlled to increase.

[0077] A protective plate (13) may be provided in front of the electrode (10a) in a first direction. The protective plate may have a thickness of at least 10 millimeters. The protective plate may block the entry of bullets. The protective plate may protect the electrode (10a) and adjacent components. The adjacent components may include wires and connections. This is because if the connecting wires and connections are severed, a complete power cutoff to the planar heating element (10) may occur. The control unit (14) may be aligned with the protective plate (13) in the first direction. Accordingly, the control unit (14) may also be protected.

[0078] An insulator may be provided adjacent to at least one of the front and rear of the first direction of the above-mentioned planar heating element. First and second insulators (11)(12) may be provided in a shape corresponding to the shape of the above-mentioned planar heating element. At least a portion of the insulators (11)(12) may be provided in contact with the plane of the first direction of the above-mentioned planar heating element. The insulator may be provided as a non-conductive material. The insulator may be provided as at least one layer of non-woven fabric, flame-retardant non-woven fabric, hot melt, and PU hot melt. The above-mentioned planar heating element (10) and the insulators (11)(12) may be referred to as a planar heating module (19). The above-mentioned planar heating module (19) may be described as having an additional structure that prevents leakage current from the planar heating element (10) through which current flows. Here, leakage current may refer to the contact of an external object with the wire of the planar heating element.

[0079] The first and second insulators (11)(12) may be the same or different. The insulators may be provided larger than the width of the planar heating element to prevent external objects (e.g., water) from coming into contact with the planar heating element. The pair of insulators (11)(12) may seal the inner and outer periphery of the planar heating element. To this end, the surface of the insulators may be provided with an adhesive layer. The adhesive layer may be provided at least on the surface where the pair of insulators (11)(12) come into contact with each other. The planar heating module (19) can be blocked from receiving external objects. Thus, a leakage current can be prevented. Here, a leakage current may indicate that water is entering from the outside and current is leaking along the water. In this way, the planar heating module (19) can achieve heating by external power and is isolated from the outside to prevent leakage current.

[0080] The above-described planar heating module (19) can be connected to a plate (18). Here, connection may be exemplified by attachment. An attachment member (17), which is an adhesive material, may be provided at the contact portion between the plate (18) and the planar heating module (19). The attachment member may be exemplified by an adhesive tape. Through the attachment member, the planar heating module maintains its shape on the plate and can maintain its shape against external loads. The plate may maintain a flat surface with a predetermined rigidity. The plate may also be provided in the form of a predetermined frame. The frame may support the planar heating module. The frame may further be provided with a component to provide the target area with specific target properties. The plate may be provided with a resin material of a thickness having a predetermined rigidity. When the plate (18) is supported from the top, it may maintain the flat shape of the first slope. The above plate (18) may not be able to maintain its shape if it is supported at the bottom.

[0081] The item in which the above-mentioned surface heating module (19) and the above-mentioned plate (18) are integrated can be referred to as the target body (70). The target body (70) may be in a state excluding the configuration of the above-mentioned protective plate (13) and the above-mentioned control unit (14). The target body (70) may be in a state in which it can operate as a target by connecting a power source.

[0082] [Composition of Planar Heating Elements]

[0083] FIG. 2 illustrates the above-mentioned planar heating element and is a drawing illustrating a first example (a) and a second example (b). Refer to FIG. 2.

[0084] According to the first example above, the heating element is a planar heating element (10), and the planar heating element may include a woven portion (10b). The woven portion (10b) may be a fabric including weft threads and warp threads. Here, the weft threads and warp threads may exemplify electrical wires. The weft threads and warp threads may be intertwined. The woven portion may extend in one direction. The one direction may refer to an extension from the first normal. The electrodes (10a) may be provided at both extended ends of the woven portion. The woven portion may include a heating module having at least two warp threads and a weft thread connecting the at least two warp threads. The woven portion may include at least two heating modules. The woven portion may be provided with a plurality of weft threads and a plurality of warp threads.

[0085] Current can flow through the electrode. At this time, the current passes through the wire providing the weaving part (10b) and can generate heat. The wire can generate ohmic heat due to electrical resistance. The generated energy can be radiated as infrared rays.

[0086] According to the second example above, the contents of the first example above may be applied. In the second example above, an additional weaving section (10c) may be provided in addition to the weaving section (10b). In this case, the weaving section (10b) may be referred to as the first weaving section, and the additional weaving section (10c) may be referred to as the second weaving section. The weft and warp of the second weaving section (10c) may be added between the weft and warp of the first weaving section. The second weaving section (10c) may be intertwined with the first weaving section. At least one of the weft and warp of the second weaving section may be thicker than at least one of the weft and warp of the first weaving section. Specifically, if the thickness of the weft is thicker, weaving stability is increased, and the durability of the weaving section may be increased. If the thickness of the slope mentioned above increases, the resistance decreases, and the amount of heat generated can be increased.

[0087] A more detailed description of the above-mentioned planar heating element is disclosed in the present inventor's published patent KR20170055181A. In addition, various examples of the above-mentioned woven portions (10a) and (10b) are disclosed in the present inventor's application KR20200166194A. The technology disclosed in the two cited documents may be included in the present disclosure in terms of the planar heating element and the detailed configuration connecting the planar heating element to the outside. Of course, this does not exclude various other embodiments.

[0088] [Composition of the Recognition Area]

[0089] The above planar heating element can use metallic wires as the weft and warp threads. Therefore, compared to fabrics using fine fibers, achieving a predetermined width on the first slope was a difficult task. In other words, the planar heating element could not change direction. For example, it was difficult to convert an extension in the second direction to the third direction. If the direction was forcibly changed, the wires would break in the stretched parts and be cut in the overlapping parts. It should be noted that the planar heating element is bent inside the first slope. To solve this problem, the inventor considered folding the planar heating module (19). The inventor did not stop at mere thought but conducted many experiments. Accordingly, a configuration that provides the recognition area (1) was discovered.

[0090] FIG. 3 is a drawing showing an enlarged view of the bending portion of the planar heating module. In FIG. 3, the shoulder portion of the torso is shown in a, the head portion is shown in b, and the lower end of the torso portion is shown in c. Refer to FIG. 3.

[0091] The above planar heating module needs to be bent while having a predetermined thickness. To this end, the planar heating module (19) can be folded to change the bending angle. Here, it is important to note that the bending occurs within the first slope. It was found that a single regular fold of the wire resists cutting strength well. Here, the folding refers to the change of the upper and lower surfaces of the planar heating module. The folding can provide various shapes of the recognition area (1) by varying the angle. Due to the folding, an overlapping portion of the planar heating module occurs in the first direction.

[0092] At the shoulder portion (a) of the torso portion, the planar heating module (19) can be bent at a wide angle. In this case, the folding angle of the planar heating module (19) may be greater than 90 degrees and less than 180 degrees. At the head portion (b), the planar heating module (19) can be bent at a right angle. In this case, the folding angle of the planar heating module (19) may be 90 degrees. At the lower end portion (c) of the torso portion, the planar heating module (19) can be bent at a right angle. In this way, various shapes can be created by varying the folding angle at the folding points.

[0093] In the folding portion disclosed in FIG. 3, by folding the planar heating module (19), the portion overlapping in the first direction may have two layers stacked in the first direction. Here, the area where the two layers are stacked may be called a two-layer area. The two-layer area may have a greater amount of heat generation than a single-layer area. A greater amount of heat generation may mean that the intensity of infrared radiation is high. In the folding portion, the planar heating module (19) may be stacked in at least three layers. FIG. 4 is a drawing showing another variation of the folding portion. Refer to FIG. 4.

[0094] The above-described planar heating module (19) may include three parts (a, b, c) extending in different directions. Here, the three parts (a, b, c) may be provided by the planar heating module (19) being folded. When the three parts (a, b, c) are sufficiently adjacent, the planar heating module (19) may provide a three-layer area (193) in which three layers are stacked in the first direction. The three-layer area (193) may provide a large amount of heat in the first direction. Accordingly, the three-layer area may have a greater amount of heat than the two-layer area. It may emit stronger infrared radiation. Stronger infrared radiation may mean greater visibility. The three-layer area, the two-layer area, and other areas in which more layers are stacked may be referred to as a multi-layer area. The multi-layer area may be provided in various ways as needed. This may be an advantage of the present disclosure.

[0095] When the three parts (a, b, c) are sufficiently adjacent, the shape area (d) can be provided by the plane heating module (19) being adjacent to each other. Areas that cannot be provided by the width of the plane heating module (19) alone can be provided through the shape area. The width of the shape area may be greater than the width of the plane heating module (19). Here, the width may refer to the straight-line distance connecting the target area and the non-target area within the recognition area (1). For example, the length of a first straight line connecting the target area and the non-target area at any point in the shape area (193) and a second straight line connecting the target area and the non-target area at any point outside the shape area can be compared. At least one of the second straight lines may be longer than the first straight line. By providing the shape area (193), the target can be provided in a more diverse shape.

[0096] The above-mentioned planar heating module (19) may not be folded, but only the planar heating element (10) may be folded. In this case, the insulator (11)(12) may be provided on the upper and lower surfaces in the first direction of the planar heating element (10) having the folded part. Accordingly, leakage current caused by folding can be prevented.

[0097] FIG. 5 illustrates a target made by folding the above-described planar heating module, showing a photograph of an actual wild boar (a) and a target made with the above-described planar heating module (b). Refer to FIG. 5.

[0098] In order to provide the above target (T), the recognition area (1) can be provided by the above surface heating module (19). At this time, multiple folding points may occur. The recognition area can be extended along the boundary indicating a wild boar. The recognition area has a predetermined thickness. Accordingly, sufficient visibility can be secured when using a thermal imaging sight. Of course, the observer can recognize it as a wild boar.

[0099] The above multilayer area can be provided in the leg portion of the wild boar to provide a high heat output. The above shape area (193) can be provided in the leg portion of the wild boar. Accordingly, the visibility of the leg portion of the wild boar can be increased. The observer can more strongly recognize that the part provided in a predetermined shape is the leg portion of the wild boar.

[0100] In the present disclosure, the recognition area may be an area that must not be hit by a bullet. Nevertheless, the recognition area (1) may be hit by a bullet due to zeroing and firing errors. In this case, damage may occur to the planar heating element (10) providing the recognition area. Nevertheless, due to the configuration of the woven portion (10b)(10c), the planar heating element may not be open. The woven portion may be provided by interlacing with one another. Therefore, even if several weft and warp threads in a specific part are broken, current may flow through the weft and warp threads adjacent to the specific part. Accordingly, current may continue to flow. Current may also flow in the part extending in the direction of extension of the planar heating element from the specific part. Accordingly, the heating area of ​​the planar heating element can be maintained stably without the heating area decreasing.

[0101] In other words, the ohmic heat may not be generated in the aforementioned specific part. However, all parts separated by a predetermined distance in the extension direction of the planar heating element from the aforementioned specific part can generate ohmic heat.

[0102] FIG. 6 illustrates the back surface (a) of the plate and the image (b) of the thermal imaging sight when the recognition area is hit. Refer to FIG. 6.

[0103] A situation (S) in which multiple impact holes (h) occur is compared with a thermal image (I) in that situation (S). Even in the situation (S) in which multiple impact holes occur, it can be seen that the heat generated by the surface heating element is maintained overall.

[0104] In addition, the range of interest of the above thermal image (I) can be expanded. In this case, it can be seen that the planar heating element at a location spaced apart by a predetermined distance in the extension direction of the planar heating element from the above impact hole (h) also heats up uniformly in the width direction of the planar heating element.

[0105] Accordingly, even if the above recognition area is hit, the planar heating element can operate until all slopes at a specific point are cut. Accordingly, there is an effect that the heating area of ​​the planar heating element is not reduced, and there is an advantage that the lifespan of the target body (70) is extended.

[0106] FIG. 7 illustrates targets of various shapes. As illustrated in FIG. 7, the recognition area of ​​the present disclosure can freely produce targets of various shapes. In the case of providing a deer shape, antlers can be produced using the shape area (d).

[0107] [Example of deformation of the end of the recognition area]

[0108] The above recognition area (1) can be provided as a planar heating module (19). The two ends of the above recognition area (1) can be adjacent to each other. Accordingly, a single planar heating module can provide a more perfect shape. If two or more planar heating modules are required, the manufacturing cost increases and the structure may become more complex. The electrodes at the ends of the planar heating modules do not come into contact with each other. This prevents short circuits in the planar heating element. The planar heating modules can overlap each other in the first direction. Accordingly, the virtual line connecting the end of the planar heating module (which may also be understood as a planar heating element) and the end of the planar heating module (which may also be understood as a planar heating element) may have variations. FIG. 8 is a modified example of the end of the planar heating module and the virtual line connecting the end, where a is the case where the planar heating module does not overlap, b and c are the cases where the planar heating module overlaps, and c is the case where the end of the planar heating module overlaps. Refer to FIG. 8.

[0109] (a) The virtual line connecting the two ends of the planar heating module can clearly define a single target area (2). This modified example may be preferred to achieve the purpose of preventing short circuits of the electrodes. This is because a pair of the electrodes (10a) are spaced apart, and the planar heating elements adjacent to the electrodes do not overlap each other.

[0110] (b) The extensions of the planar heating module may overlap each other in the first direction. A virtual line connecting the two ends of the planar heating module may be provided in the non-target area (3) or another target area (1). In this case, the original target area may be provided by the planar heating module alone. The two ends of the planar heating module and the virtual line connecting them may provide the other target area (1). This modified example may be preferred in cases corresponding to various shapes. However, there is a risk of a short circuit occurring if a bullet hits the area where adjacent planar heating elements overlap at the electrode.

[0111] (c) The two ends of the planar heating module may overlap in the first direction. In this case, the target area may be provided by the planar heating module alone. This modified example may be preferred when corresponding to various and perfect shapes. However, there is a risk of a short circuit occurring if a bullet hits the area where adjacent planar heating elements overlap at the electrode. There may be a problem in that the risk of a short circuit increases as the overlapping area becomes wider.

[0112] Variations for the ends of the above recognition area may be selectively applied to provide various shapes of the target.

[0113] <2nd Example>

[0114] In addition to the aforementioned thermal scope, night vision devices are another method for identifying targets in dark places. The way the aforementioned night vision device and the thermal scope identify targets in dark places differs in their operating principles, operating environments, and image characteristics. Regarding operating principles, the thermal scope detects infrared radiation emitted from objects, whereas the night vision device amplifies and recognizes light reflected from objects. Regarding operating environments, the thermal scope can operate even in complete darkness, whereas the night vision device requires at least some ambient light to operate. Regarding image characteristics, the thermal scope displays in color or black and white, whereas the night vision device displays in green. Due to these differences in characteristics, the thermal scope has the advantage of being able to identify objects even in the presence of fog, but it has the disadvantage that observation becomes impossible when objects such as glass are present. The above night vision device has the advantage of being able to accurately identify objects, but it has the disadvantage of not being usable in environments with no light at all.

[0115] The second embodiment presents an embodiment of a target suitable for use as a target for the night vision device. The configuration of the target of the first embodiment may be applied to the second embodiment. For example, [configuration of the target], [configuration of the planar heating element], [configuration of the recognition area], and [modified example of the end of the recognition area] may be identical or similar to the first embodiment.

[0116] FIG. 9 is an image of a thermal imaging sight as an experimental screen illustrating the features of the second embodiment. Refer to FIG. 9.

[0117] Part a is the part where a metal plate with high reflectivity and low emissivity is placed, and part b is the part where a heating plate is placed. The metal plate may be placed on the heating plate. In the image acquired by the thermal imaging sight, part a appears dark, and part b appears bright. This may mean that part a has a low temperature and part b has a high temperature. In this way, when using a metal plate with low emissivity, even if the temperature is high, it may appear low to a thermal imaging sight that detects infrared rays. When the metal plate is used in the target area (2), heat can be transferred from the recognition area (1) to the target area. However, even if the target area is heated, the visual distinction from the recognition area can be increased in the image of the thermal imaging sight. By applying the metal plate to the target area (2), greater visibility can be obtained regarding the boundary between the recognition area and the target area when using the thermal imaging sight.

[0118] As the metal plate mentioned above, a plate to which aluminum is applied may be used. The application of the aluminum is highly anticipated due to its low emissivity (0.03-0.08), ease of processing, low cost, and light weight. The aluminum may be used in a form in which aluminum is deposited on a resin film.

[0119] FIG. 10 is a target according to a second embodiment, where the left side is a front view of the target of the second embodiment and the right side is an image (I) of a thermal imaging sight. Refer to FIG. 10.

[0120] The surface heating module may be provided in the recognition area (1). The target area (2) may be provided inside the recognition area. A metal plate may be provided on the plate (18) of the target area (2). A metal thin film may be coated on the plate (18). Aluminum may be coated on the plate (18). At least a portion of the plate (18) may be exposed in the first direction (+x) without being obscured by the recognition area (1). The portion of the plate (18) exposed in the first direction (+x) may be provided with the metal plate. The plate may reflect a second light incident in the first direction (+x) in the fourth direction (-x). The plate may be a reflector. In this case, the reflector may act only on the target area. The second light may be a different light distinct from the first light. The above second light may include visible light.

[0121] In the above plate (using a metal plate) (18), multiple holes (h) caused by impact are shown. In the image of the thermal imaging sight, the holes (h) caused by impact are clearly visible. This is because the infrared radiation of the background after passing through the holes (h) is detected by the thermal imaging sight. In most cases, the background may be adjacent to the target. Thus, when the target area (2) is a metal plate, the location of impact in the target area (2) can be accurately determined. Accordingly, the location of impact can be accurately determined. This is because, due to the low emissivity of the metal plate, it emits infrared radiation distinctly from the recognition area (1) and the background.

[0122] The target (T) can be observed with the night vision device. The plate can be observed with the night vision device. In this case, the metal plate (target area) can be observed more prominently compared to other adjacent areas (recognition area and non-target area). This is because the metal plate has a high reflectivity. A non-woven fabric can be provided as the insulator (11) providing the recognition area (1). The non-woven fabric can be made of a black material. Any black material can be used for the part of the recognition area (1) that is exposed to the outside. In this case, the visual distinction between the target area and the recognition area can be greatly increased. The reflectivity of the non-woven fabric is lower than that of the metal plate. Accordingly, the target area (2) can be visually recognized more prominently compared to the recognition area (1).

[0123] In the second embodiment, a plate material with high reflectivity and low emissivity is used in the target area. According to this, when observing the target with the thermal imaging sight, the target area is detected at a temperature lower than the actual temperature, so visibility can be excellent. This is because the emissivity of the plate material is low. When observing the target with the night vision device, the reflected light of the target area is greatly amplified, so visibility can be excellent. This is because the reflectivity of the plate material is high. According to the second embodiment, there is an advantage that the target can be used in any environment. Here, the environment may include an environment where night vision devices cannot be used because there is no light, an environment where thermal imaging sights cannot be used because there are obstacles in the light path, and an environment where visibility of the recognition area is poor because the target is far or small.

[0124] <Third Embodiment>

[0125] The above target can be used in various environments. Examples include long-range targets and short-range targets, and fixed and portable types. The third embodiment presents an embodiment suitable for use as a short-range target and a portable type. In the third embodiment, the configuration of the targets of the first and second embodiments may be applied. The third embodiment will be described focusing on the parts where it differs from other embodiments. For example, [configuration of the target], [configuration of the planar heating element], [configuration of the recognition area], and [modified example of the end of the recognition area] may be the same or similar to the first and second embodiments.

[0126] FIG. 11 is a front perspective view (a), a side view (b), and a rear perspective view (c) of a target according to a third embodiment. Refer to FIG. 11.

[0127] A board (20) is provided on the rear or back side of the target body (70). The rear and back side may be the back or rear direction of the plate (18) that is not visible to an observer. The board may be a rigid member having enough rigidity to maintain its shape and stand upright on its own. The board (20) may be provided as a part of the plate (18). Here, the part may be described as being integral and not requiring separation. To ensure ease of processing and rigidity, the board (20) may be made of a material having a predetermined thickness made of cork. The board (20) may be made of a plate-shaped material having a predetermined thickness made of cork. The board may be a cork board.

[0128] On the front surface of the board (20), the recognition area (1) and the target area (2) may be provided. The third embodiment may not provide a non-target area (3). A surface heating module (19) may be provided in the recognition area (1).

[0129] By utilizing the board (20), the target body (70) can maintain the shape of the target regardless of which part is grasped. That is, it can maintain an attitude perpendicular to the first direction viewed by the observer. This can be a distinguishing feature from the first and second embodiments. As an example, the protective plate (13) and the control unit (14) can be provided at the front and rear of the target body (70), respectively. The protective plate (13) and the control unit (14) can support the target body from the front and rear. Accordingly, the target body can stand upright. As an example, the protective plate (13) and the control unit (14) are aligned in the first direction at the bottom center of the target body (70). This is to prevent the target's attitude from shifting upon impact. As long as a solid attitude fixation is possible, the protective plate (13) and the control unit (14) can be placed at any corner of the target body (70). Even if the target body (70) is hit, the bullet can easily penetrate and break the board. The target body (70) can maintain its upright position. The target body can be used as a target for multiple shots.

[0130] The target of the third embodiment can maintain an upright position on its own. The size of the target can be approximately 30 x 20 centimeters in the first normal direction, making it portable. The target has the advantage of being portable and mountable, allowing it to be used immediately as needed.

[0131] <3-1 Example>

[0132] The plate (18) can provide the target area (2). The planar heating module (19) can provide the recognition area (1). This is clear through the first to third embodiments. Furthermore, the plate (18) and the planar heating module (19) can be placed together on the first slope. This is because there is no substantial difference from an engineering perspective. The 3-1 embodiment presents a case where the target area and the recognition area cannot be considered as the same plane from an engineering perspective. In the 3-1 embodiment, the configuration of the target of the third embodiment may be applied. The explanation will focus on the parts where the 3-1 embodiment differs from the third embodiment.

[0133] FIG. 12 is a side cross-sectional view of a target according to the 3-1 embodiment. Refer to FIG. 12.

[0134] The surface heating module (19) is provided on the front of the board (20). The plate (18) is provided on the rear of the board (20). The portion of the board (20) corresponding to the plate (18) may be cut. The recognition area (1) and the target area (2) may be spaced apart by a distance equal to the thickness of the board.

[0135] In this case, from an engineering perspective, the recognition area (1) and the target area (2) cannot be said to be on the same plane. However, the target area (2) is positioned within the inner area of ​​the recognition area (1), and accordingly, the target area can be easily identified. This is because, as a result of an observer observing in the first direction, the target area (2) is perceived to be located within the inner area of ​​the recognition area (1). In other words, when an observer observes the target in the first direction, both the recognition area (1) and the target area (2) can be positioned on the first slope. The target of the present disclosure may have a configuration in which the target area (2) is located within the inner area of ​​the recognition area (1) in response to the observer observing in the first direction. The result is the same in this embodiment.

[0136] The target body (70) can be erected by means of a supporter (31). A groove is provided in the supporter, and the target body (70) can be fitted into the groove. The supporter may include the protective plate and the control unit. The protective plate and the control unit may serve as the supporter by being fastened together.

[0137] <Fourth Example>

[0138] The above plate (18) corresponds to the target area (2), and the above planar heating module (19) corresponds to the recognition area (1). As a result, the above plate is an item that is frequently discarded after being hit, while the above planar heating module (19) is an item that is not hit. The above planar heating module is an expensive item compared to the above plate. The inventor researched a technology that allows the above planar heating module to be used for a long period of time. As a result, the inventor arrived at the fourth embodiment. The fourth embodiment presents an embodiment in which the above planar heating module can be used repeatedly. The configuration of all the above embodiments may be applied to the fourth embodiment. A specific example is explained by exemplifying the above 3-1 embodiment.

[0139] FIG. 13 is a perspective view of a target according to a fourth embodiment. Refer to FIG. 13.

[0140] The plate (18) and the board (20) may be provided as separate parts. That is, the board is not a part of the plate, and is different from the third embodiment.

[0141] The above plate and the above board may be separate parts for a separate target. In this case, the above plate (18) may be referred to as the first plate and the above board (20) as the second plate. That is, the two parts can cooperate to perform the function of the above plate (18). The above first plate (18) provides a target area, and the above second plate (i.e., board) (20) can maintain the shape and form of the recognition area (including the above planar heating element) (1). The description of this paragraph may also be applied to other embodiments in which the role of the above plate (18) is separated.

[0142] A fastener (181)(182) that is easy to fasten and detach (free enough to be removed by hand) may be provided on the facing surfaces of the plate and the board. The fastener may include a surface fastener (e.g., Velcro (181)(182) (registered trademark), adhesive, etc.), a loop, and screws. The first plate (18) may be fastened to the second plate (20) by means of the fastener.

[0143] When the above target area (2) is removed and use is terminated, the plate can be removed and discarded, and a new plate can be attached. Accordingly, the above surface heating module can be used repeatedly. Consequently, the product can be used for a long period of time.

[0144] An embodiment in which the fastener is applied even when the board (20) is not present is possible. For example, the planar heating module (19) can perform the role of the board. For example, the fastener may be attached to the rear surface of the planar heating module and the front surface of the plate.

[0145] <5th Example>

[0146] The above target can be used in various environments. For example, it can be used in rainy or high-humidity environments. Since the above planar heating module (19) conducts electricity, there is a great need for sealing. The above target requires the mass production of identical products. The fifth embodiment proposes a target that satisfies general usability and mass production. In the fifth embodiment, the configuration of the targets of the first to fourth embodiments may be applied. The fifth embodiment will be explained focusing on the parts where it differs from the other embodiments.

[0147] FIG. 14 is a plan view of a target according to the fifth embodiment. Refer to FIG. 14.

[0148] The above target may be a plate-shaped member extending along the first normal. The plate (18) is placed in the center of the target as the target area (2). The planar heating module (19) is placed in the periphery of the target as the recognition area (10). The inner and outer circumferences of the planar heating module (19) may be sealed. Both sides of the planar heating module (19) may be sealed. A wire (52) may be drawn out between the sealed surfaces. The wire (52) may be connected to the electrode (10a) of the planar heating element (10). The plate (18) may be attached to one side of the planar heating module (19). By attaching the planar heating module (19) and the plate (18), the target body (70) may be provided.

[0149] In the above planar heating module (19), the width of the planar heating element (10) may be smaller than the width of the insulator (11)(12). With the planar heating element in between, the inner surfaces of the insulators (11)(12) may be connected to each other. A pair of the insulators has a first portion that does not come into contact with each other due to the intervention of the planar heating element. A pair of the insulators has a second portion that comes into contact with each other without the intervention of the planar heating element. An adhesive may be applied to the second portion. A pressure-sensitive adhesive may be applied to the second portion. The planar heating module may be sealed by the second portion. An adhesive or pressure-sensitive adhesive may also be applied to the first portion. Accordingly, the planar heating element can be firmly fixed.

[0150] The above target, particularly the target body (70) used for the above target, can be manufactured by a mass production process. The above target can be prevented from having a short circuit.

[0151] FIG. 15 illustrates a process for manufacturing the target body. FIG. 15 shows that processes (a) through (f) can be performed sequentially. Refer to FIG. 15.

[0152] Refer to (a). The surface heating module (19) may be provided folded into a predetermined shape on one side of the protective film (11a). The protective film (11a) may be provided as a part of the insulator (11). The protective film (11a) may be a PU film. One layer of the protective film may include a material layer with high emissivity. One layer of the protective film may include a base layer. One layer of the protective film may include an adhesive layer. An adhesive or pressure-sensitive adhesive may be applied to the adhesive layer.

[0153] A pre-assembly member (51) may be attached to the folded portion of the above-mentioned planar heating module (19). Here, the planar heating module (19) may include an insulating layer such as non-woven fabric, and the above-mentioned protective film (11a) may be excluded. The above-mentioned pre-assembly member may be an example of a tape. The above-mentioned pre-assembly member may press the folded portion to adhere it to the above-mentioned protective film (11a). The above-mentioned pre-assembly member (51) may prevent the folded planar heating module (19) from unfolding. This prevents defects from occurring during the subsequent compression process. The above-mentioned pre-assembly member may be provided at all places where the planar heating module is folded.

[0154] Refer to (b). The wire (52) can be connected to the electrode (10a). The pre-assembly member (51) can be fastened at the location where the electrode (10a) and the wire (52) are connected. The pre-assembly member (51) can bring the electrode (10a) and the wire (52) into close contact with the protective film (11a). By doing so, defects in the subsequent compression process can be prevented.

[0155] Refer to (c). Another protective film (12a) is placed over the above-mentioned pre-assembled member (51). The protective film (11a) and the other protective film (12a) may be the same material. The protective film (11a) and the other protective film (12a) may be attached to each other with different parts inside. To this end, an adhesive or adhesive may be applied between the protective film (11a) and the other protective film (12a).

[0156] Refer to (d). Subsequently, the surface heating module (19) can be sealed by compressing the protective film (11a) and the other protective film (12a). A presser that applies pressure and heat may be used in the compression process. With the surface heating element (10) placed in the center, both the inside and outside of the surface heating element (10) can be sealed. (e) shows an intermediate body in which the process up to this point is completed. In this state, intrusion or damage by external objects can be prevented. In the state of the intermediate body, long-distance movement and transport may be possible.

[0157] Refer to (f). Subsequently, the inner region of the surface heating module (19) can be cut out. The target region (2) can be provided in the cut-out region. A recognition region (1) can be provided outside the target region (2).

[0158] Refer to (g). The attachment member (17) can be attached to one side of the recognition area (1) in the intermediate. The attachment member may be double-sided tape. The double-sided tape may have adhesive properties on both sides. One side of the attachment member (17) may be attached to the recognition area (1). Afterward, the release liner on the other side of the attachment member may be removed, and the plate (18) may be attached.

[0159] When the above process is completed, the target body (70) of FIG. 14 can be provided.

[0160] <6th Example>

[0161] The target of the present disclosure can be used as a portable short-range target. In this case, it may have the purpose of protecting the control unit, convenience of assembly, and maintaining a vertical direction relative to the first direction. For example, a process of connecting the protection plate (13) of the third embodiment, the target body (70), and the control unit (14) is required. The sixth embodiment is described by reference to the third embodiment, but is not limited thereto, and the configurations of the targets of the first to fifth embodiments may be applied.

[0162] FIG. 16 is a diagram illustrating the manufacturing process of the target according to the 6th embodiment. Refer to FIG. 16.

[0163] With the target body (70) placed in the center, the protective plate (13) may be placed on the front (+x side) and the control unit (14) may be placed on the rear (-x side).

[0168] <7th Example>

[0169] The target of the present disclosure presents an embodiment capable of changing the characteristics of the target area. In the second embodiment, a target capable of accommodating both the thermal imaging sight and the night vision scope was presented. The output of the recognition area can be adjusted to correspond to the specifications or operation of the thermal imaging sight. It is not easy to correspond to the specifications or operation of the night vision scope. The fourth embodiment presented the use of Velcro, but this may be limited to short-range and small targets. The present embodiment proposes an embodiment capable of varying the target area in correspondence with the night vision scope. Any explanation lacking in the description of the present embodiment may be applied as is in the descriptions of the first to sixth embodiments.

[0170] FIGS. 17 and 18 are drawings illustrating a target according to a seventh embodiment. FIG. 17 may be a target having both a head and a torso. FIG. 18 may be a target having a head and a chest. Refer to FIGS. 17 and 18.

[0171] The target body (70) may be provided in a pocket shape with an open front. The planar heating module (19) and the plate (18) may have at least a portion of their outer circumferences having the same shape. The outer circumferences of the planar heating module (19) and the plate (18) may each have the same shape. The outer circumferences of the planar heating module (19) and the plate (18) may be connected to each other. Some portions of the outer circumferences of the planar heating module (19) and the plate (18) may not be connected to each other. The portion of the outer circumference of the planar heating module (19) and the plate (18) that is not connected may provide an open hole (71). The open hole (71) may be provided at the bottom when viewed from the direction of gravity. In this way, the planar heating module (19) and the plate (18) are connected with the remaining outer portion while a part of the outer circumference is open, so that the planar heating module (19) and the plate (18) can provide a pocket shape. The pocket shape may mean that an external object can enter and exit through the open hole (71).

[0172] The above-mentioned planar heating module (19) may correspond to the above-mentioned recognition area (1). The inner area of ​​the above-mentioned recognition area (1) may be open. Through the open inner area, the plate (18) may be observed in the first direction. The plate (18) may be the target area. Some part of the plate (18) may overlap with the planar heating module (19) in the first direction. The overlapping part may not function as the target area. It can be seen that some part of the plate (18) does not become the target area (2). Other parts of the plate (18) may not overlap with the planar heating module (19) in the first direction. At least other parts of the plate (18) may correspond to the target area (2). The plate (18) may correspond to the target area (2). The outer area of ​​the above recognition area (1) may correspond to a non-target area (3). In the target of this embodiment, the target area (2) may be provided in the inner area of ​​the above recognition area (1) in response to observation in the first direction. In other words, the above recognition area and the target area may not lie strictly on the same plane. Nevertheless, in response to observation in the first direction, the above recognition area, the target area, and the non-target area may be placed together on the first slope.

[0173] The target body (70) can be connected to the control unit (14) by a wire (52). Power consumption may vary depending on the size and specifications of the target body. The wire (52) may have a predetermined length (e.g., 6 meters). The wire may include a sealed waterproof connector.

[0174] The control unit (14) may include a temperature controller. The control unit (14) may include a battery. The heating state of the surface heating module (19) can be controlled according to the control of the control unit.

[0175] A support post supporting the target body (70) may be inserted into the open hole (71). Here, the support post may not obstruct the plate (18) from being observed from the first direction. For example, an observer may perceive the plate (18) as the target area (2). In this case, the plate (18) may be the first plate (see 4th embodiment). In this case, the support post may only perform the function of the second plate (see 4th embodiment).

[0176] A standing body (e.g., see 81 in FIG. 20) capable of having the target area (2) may be inserted into the opening hole (71). The standing body may have a wide surface corresponding to the size of the opening hole (71). The standing body may be supported on the ground or on a wall. The part of the standing body that is inserted into the opening hole (71) may provide the target area (2). The target area may be made of a material having various reflectivity. Various materials such as wood, ceramic, plastic, and metal may be used. Various materials such as aluminum, copper, iron, and stainless steel may be used as the metal. Accordingly, the target may be used in various forms to suit the operating state of the night vision device.

[0177] Even without the above support, the target body (70) of this embodiment can be used as a target. For example, it can be used by fixing the periphery.

[0178] FIG. 19 is a cross-sectional view taken by cutting the adjacent position of the open hole along the extension direction of the open hole. That is, it is a cross-sectional view of 19-19'. Refer to FIG. 19.

[0179] The plate (18) of the target body (70) of the 7th embodiment may use a waterproof material. The waterproof material may use a waterproof cloth made of fabric. The waterproof cloth may have a certain reflectivity. The waterproof cloth may provide the target area (2). Water entering from the rear can be blocked by the waterproof cloth. Accordingly, the target can be used even in bad weather.

[0180] As described, the inner portion of the recognition area (1) provided by the surface heating module (19) may be open. Through the open portion, the waterproof fabric (the waterproof fabric may be the plate (18)) may be exposed to the front in the first direction. The connection portion between the plate (18) and the surface heating module (19) may be airtight. The outer portions of the plate (18) and the surface heating module (19) may be joined together. A waterproof fabric may be used at the joint of the two members. A narrow fabric (75) may be used. The narrow fabric may be treated with water-repellent and water pressure-resistant processing to enhance the waterproofing effect. Accordingly, water may not enter through the joint of the two members. Accordingly, the target can be used even in bad weather.

[0181] A waterproof resin (11c)(12c) may be further used as a component of the above insulating layer (11)(12). For example, the resin may be made of TPU (Thermoplastic Polyurethane). The waterproof resin can prevent water from entering.

[0182] An adhesive or sealant may be further added between the surfaces of the plate (18) and the planar heating module (19) that come into contact with each other. Accordingly, leakage current from the planar heating element (10) may not occur.

[0183] The contact points between the plate (18) and the planar heating module (19) may be spaced apart from each other. Accordingly, the open hole (71) may be provided. A member providing a target area (2) may be inserted and withdrawn through the open hole. According to the present embodiment, the target area of ​​the target body can be actively varied in response to night vision. According to the present embodiment, the target body can be used even in bad weather.

[0184] <Eighth Example>

[0185] The target of the present disclosure presents an embodiment capable of enhancing the sense of impact. In the seventh embodiment, a member that generates a striking sound may be used as the support member that is inserted into and removed from the open hole (71). According to this, when a bullet hits the target area, the fact of impact can be detected through sound. Any explanation lacking in the description of the present embodiment may be applied as is to the description of the seventh embodiment.

[0186] [Method of securing the target]

[0187] FIG. 20 illustrates a method of using the target according to the present embodiment. FIG. 20 presents (a) to (h) in sequence. Refer to FIG. 20.

[0188] First, the support (81) is described. A rigid plate may be used as the material for the support (81). A metal plate may be used for the rigid plate. The metal plate may be provided with a protrusion (82) that amplifies the impact sound upon impact. The support may have a rigid plate with the same shape as the outer circumference of the first direction of the target body (70). The outer circumference of the support may be slightly smaller than that of the target body (70). This is to allow the support to be inserted. The support can be inserted into the pocket-shaped target body (70). The target body (70) can stand upright by means of the support (81). The support can be likened to a person, and the target body to clothing.

[0189] The above support (81) can provide the first and second plates (see 4th embodiment). The above support (81) can provide the functions of the first plate and the second plate together. In this case, the target body (70) can also provide the first plate. In other words, the plate (here, waterproof cloth) (18) of the target body (70) can provide the first plate that provides the target area (2). However, the support (81) can be shielded after being fastened. In other words, the plate (18) can be observed by an observer in a first direction and recognized as the target area. Depending on the mode of use (i.e., the state in which the support is inserted into the open hole), the plate (18) can be shielded in a first direction by the support (81). In this case, the support (81) can provide the target area. In this case, the support (81) can provide the functions of the first plate and the second plate together.

[0190] The above support (81) can operate as part of a popper system. The above popper system may refer to a system that has the function of falling over upon impact with a bullet. The above support can generate a striking sound and fall over upon impact. Here, the support may include the rigid plate inserted into the above target body (70).

[0191] Refer to FIG. 20(a). The support (81) is inserted through the open hole (71) of the target body (70). The portion of the support inserted may include the rigid plate. When observed from the first direction, the support and the target body may have the same shape. The support may be slightly smaller in size compared to the target body.

[0192] Refer to FIG. 20(b). Due to the difference in size between the support and the target body, the support can be smoothly inserted into the interior of the target body.

[0193] Refer to (c)(d) of FIG. 20. When the above-mentioned posts are fully inserted, some of the above-mentioned posts (81) may be exposed in the first direction (+x). The exposed posts may be the target area (2). The above-mentioned posts may operate as a puffer system.

[0194] Refer to FIG. 20(e). After the support is fully inserted into the target body, a wire (52) can be connected. The wire may include a first wire (521) drawn out from the target body (70), a third wire (523) with one end connected to a waterproof connector connected to the control unit (14), and a second wire (522) that can terminally connect the third wire (523) and the first wire (521). Here, the second and third wires (522) (523) can be moved while connected. The first and second wires (521) (522) can be connected at the site.

[0195] Refer to (f) of FIG. 20. The waterproof connector can be connected to the control unit (14).

[0196] Refer to (g) of FIG. 20. It illustrates the state in which the waterproof connector is connected to the control unit.

[0197] Refer to (h) of FIG. 20. Afterwards, the control panel (141) of the control unit can be operated to control the amount of heat generated by the target body and the intensity of the infrared radiation.

[0198] [Target Output Control Method]

[0199] The above target body needs to generate a predetermined amount of heat (infrared intensity) for a predetermined period of time. This can be considered a basic specification for training and leisure use. The inventor may conduct additional research activities to satisfy the specifications. As a result, for example, when using a DC 24V, 30Ah capacity battery, the amount of heat generated was controlled by setting and controlling the voltage and current, and the temperature was measured. The results are shown in Table 1. Figure 21 is a graph showing temperature versus voltage.

[0200] Set voltage (V) 5.0 6.0 7.0 8.0 9.0 10.0 11.0 12.0 13.0 14.0 15.0 16.0 17.0 18.0 19.0 20.0 21.0 22.0 23.0 Current (I) 0.5 0.6 0.7 0.8 0.9 1.0 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2.0 2.1 2.2 2.3 Power consumption (W) 2.6 3.7 5.0 6.6 8.3 10.2 12.4 14.7 17.2 19.9 22.8 25.9 29.1 32.5 36.1 39.8 43.9 48.0 52.3 Temperature (°C) 31.2 32.3 33.0 34.1 35.7 36.1 37.0 40.3 40.5 44.3 45.1 48.1 50.3 53.7 56.1 59.4 60.8 63.8 67.0

[0201] The embodiment of FIG. 17 needs to satisfy a usage time of 300 hours based on a minimum of 2.5W and 12 hours based on a maximum of 60W. Accordingly, when the external temperature is 25℃, it was possible to use it for 48 hours when the target surface temperature is 37℃ and the power consumption is 15W.

[0202] In the case of the embodiment of Fig. 18, it is necessary to satisfy a usage time of 210 hours based on a minimum of 3.5W and 9 hours based on a maximum of 80W. Accordingly, when the external temperature is 25℃, it was possible to use it for 60 hours when applying a power consumption of 12W and a thermal image target surface temperature of 37℃.

[0203] Thus, the target of the present disclosure can realize the advantage of being used for a long time at a low cost in an environment where only the target area can be replaced, with a target of various shapes, in a situation with high visibility, using either a thermal imaging sight or a night vision scope, in an environment where commercial power is unavailable and even in bad weather, for the time required by the customer.
