Technical Field

The present invention relates to an insect trap, and more particularly, to an insect trap which sucks and traps insects attracted by attraction light into an air flow formed by an intake fan.

Background

Recently, there are increasing pests due to climatic and social effects such as global warming and environmental policy. Pests not only cause damage to crops and livestock, but also carry pathogenic bacteria such as malaria, dengue fever, epidemic encephalitis B and the like, thereby causing adverse effects on human beings. In particular, recently, research on mosquito-killing-related methods has been more actively conducted due to the spread of zika virus (ZIKV) infection terrorism.

As for the method of killing insects, a chemical prevention method using an insecticide, a biological prevention method using loach or the like, a physical prevention method in which pests are attracted by a mosquito-attracting lamp, carbon dioxide gas or the like and then repelled by high voltage or the like, an environmental prevention method in which a water pit is eliminated or the surrounding environment is improved so that larvae cannot survive, and the like have been tried. However, in the case of chemical preventive methods, secondary pollution problems are raised, and biological preventive methods, environmental preventive methods, and the like require relatively much cost, processing time, and effort, and in the case of physical preventive methods using insect-killing or catching devices, there are problems in that the apparatus is complicated in structure, the convenience of users is lowered, or there is a risk associated with inclusion of high-voltage devices.

[ first embodiment ]

Fig. 1 is a side view illustrating an insect trap of an embodiment of the present invention, fig. 2 is a sectional view illustrating an insect trap of an embodiment of the present invention, and fig. 3 is an exploded perspective view illustrating an insect trap of an embodiment of the present invention.

The respective constitutions of the insect trap 1000 according to one embodiment of the present invention will be described in detail with reference to fig. 1 to 3.

The insect trap 1000 according to an embodiment of the present invention may include: a main body 110; an insect passage unit 120 detachably disposed on the main body 110 and selectively allowing insects to pass therethrough; an air dust collecting part 130 disposed at a lower portion of the main body 110; a motor 140 positioned between the air dust collector 130 and the insect passage part 120; a suction fan 150 positioned between the motor 140 and the air dust collector 130, and rotated by the motor 140; a UV LED mounting part 160 disposed on the upper part of the insect passage part 120 and having a UV LED module 161 mounted thereon; and a catching part 170 detachably disposed at a lower portion of the air dust collecting part 130 to catch the insects.

The insect referred to in the present invention is not limited to its species, and includes various kinds of flying insects, and may be particularly referred to as a mosquito.

Main body 110

The shape of the body 110 is not particularly limited, but the suction fan 150 may be cylindrical in shape and may be made of a plastic material, which is used for a long time indoor or outdoor use and does not significantly increase the manufacturing cost, since the suction fan is installed inside. The main body 110 has a structure opened up and down so that air can pass up and down. In addition, the height of the body 110 may be 2cm to 20cm, and preferably, may be 3cm to 10 cm.

Referring to fig. 2 and 3, the insect passing part 120, the motor 140 and the suction fan 150 may be installed at the main body 110 from the upper portion to the lower portion of the main body 110.

Fig. 4 is a view showing an insect passing part 120 of the insect trap according to one embodiment of the present invention.

Referring to fig. 4, the insect passage part 120 has a lattice shape including a plurality of insect passage holes 121 through which insects can selectively pass, and the plurality of insect passage holes may be formed by a circular member 122 and a radial member 123. Specifically, the size of the insect passing holes 121 may be adjusted in consideration of the average size of the insects to be caught, and as shown in fig. 4, when the insect passing part 120 is in a lattice form, the size of the insect passing holes 121 can be effectively controlled at a low manufacturing cost.

In the case of an insect trap for trapping insects by a conventionally used suction fan, there are problems that insects such as butterflies, dragonflies, and flies, which have a larger volume than mosquitoes, are also trapped together, the replacement cycle of the trap part is fast, or beneficial insects connected to non-injurious insects are also trapped, thereby adversely affecting ecosystem. In addition, the insect having a large volume is stuck to the suction fan, and there are problems that the life of the motor is shortened and the suction fan generates noise. Accordingly, the inventors of the present invention economically manufacture the insect passing part 120 while controlling the size of the insect passing hole 121 so that the insect trap 1000 can selectively suck in insects.

The plurality of insect passage holes 121 are divided by a plurality of circular members 122 and radial members 123 centered on the center of the insect passage portion 120, and have a fan shape with a center angle of 20 ° to 40 °, each circular member 122 may be spaced apart from an adjacent circular member 122 by 1.0cm to 1.5cm, and within the numerical range, the area of one of the insect passage holes 121 may be 100 mm²To 225 mm². Therefore, insects, particularly mosquitoes, selectively pass through the insect trap 1000, and insects having a large size such as butterflies, dragonflies, and flies are not caught in the insect trap, so that it is possible to prevent the durability of the motor from being deteriorated or to reduce noise generated from the suction fan 150.

Further, it is preferable that the suction fan 150 is controlled such that insects flow into the lower portion of the suction fan 150 without being adhered to the suction fan 150. In the insect trap for catching insects by using the suction fan used in the prior art, the insects are adhered to the fan blade, the rotation radius of the suction fan is not uniform, and the durability of the motor is deteriorated or noise is generated. However, when the rotation speed of the suction fan is reduced in order to make the insects not stick to the fan blades, there is a problem that the efficiency of catching the insects adjacent to the insect trap is significantly reduced. That is, the insects have a tendency to stop flying at a wind speed of 0.8m/s or more, but when the wind speed is excessively high, the insects attempt to escape from the air stream, and thus the present inventors manufactured the insect trap 1000 such that the mosquitoes stop flying while the insects are not stuck to the fan blades 151, and are caught by the suction air stream generated by the suction fan 150.

For this, the fan blades 151 may be 2 to 7, preferably, 3 or 4, and the rotation speed of the suction fan 150 may be 1500rpm to 2700rpm, preferably, 1900rpm to 2300 rpm. The fan blades 151 may be curved with a predetermined or predetermined curvature instead of being flat, and a height difference between the lowermost end and the uppermost end of the fan blades 151 in the curved shape may be 5 mm to 30 mm. On the other hand, the diameter of the suction fan 150 may be 60 mm to 120 mm, and preferably, may be 80 mm to 110 mm. Also, controlling the shortest distance of the suction fan 150 from the inner wall of the main body 110 to be 1 mm to 2.5 mm makes it possible to effectively form a suction air flow while minimizing noise caused by the suction fan 150.

In addition, a ratio of a vertical distance by which the UV LED mounting part 160 is spaced apart from the main body 110 to a height of the main body 110 may be 1:1 to 1:2, and a ratio of a vertical distance by which the UV LED mounting part 160 is spaced apart from the catching part 170 to a height of the catching part 170 may be 1:0.5 to 1:2. Within the ratio range, the insects may not be adhered to the suction fan 150, and at the same time, the insects near the insect trap 1000 may be easily sucked. In this case, the UV LED mounting part may be spaced apart from the upper end of the catching part by a vertical distance of 3cm to 30 cm.

Therefore, in the size range, the speed of the air flow formed by the suction fan 150 between the insect passage part 120 and the UV LED mounting part 160 may be controlled to be 0.5m/s to 3m/s, preferably 0.8m/s to 2m/s, and the insects may be stopped from flying while not sticking to the suction fan 150, and may be efficiently caught in the catching part 170, and the noise generated by the suction fan 150 may be suppressed.

In addition, the motor 140 is installed at a lower portion of the insect passage part 120, and the suction fan 150 is installed at a lower portion thereof to be attached to the motor 140, so that the insect trap 1000 can remarkably reduce noise generated by the motor 140 and the suction fan 150. For example, the noise measured at a distance of 1.5m horizontally spaced from the trap may be below 40 dBA.

Air dust collecting part 130

Fig. 5 is a view showing an air dust collecting part according to an embodiment of the present invention.

The air dust collecting part 130 may be attached to a lower portion of the main body 110, and may include air dust collecting part spokes 131, an air dust collecting part side port 132, and an air dust collecting discharge port 133, so that the insects flowing in by the suction fan 150 are discharged to the catching part 170, and the air dust collecting part 130 may have a cone (cone) shape whose diameter is narrowed as it is farther from the suction fan 150. That is, the air dust collector 130 is preferably formed in a cone (cone) shape so that the air generated by the suction fan 150 is effectively sent to the lower catching part 170, so that the air generated by the suction fan 150 is effectively discharged to the outside of the insect trap 1000, and includes the air dust collector side port 132. The shape of the air dust collector side port 132 is not particularly limited, and may be, for example, a mesh shape, and the area of the holes formed by the mesh shape is preferably controlled so that insects, particularly mosquitoes, cannot pass through the holes.

Therefore, the air dust collector 130 further includes the air dust collector side port 132 having a controlled hole size, so that the insects flowing in by the suction fan 150 cannot escape to the outside of the insect trap 1000 after being caught in the trap 170.

On the other hand, the ratio of the diameter of the air dust collection discharge port 133 to the diameter of the suction fan 150 may satisfy 1:2 to 1:9, preferably, may be 1:3 to 1:5, and within the ratio range, the wind speed control by the suction fan 150 may be easily performed.

Catching part 170

If referring to fig. 6, the catching part 170 may include a mesh part 171, and the mesh part 171 allows air to be discharged to the outside by the suction fan 150. The mesh part 171 may include mesh part holes 173, the mesh part holes 173 may be formed between adjacent mesh part spokes 172, and the air flow generated by the suction fan 150 may be discharged to the outside of the catching part 170, and the mesh part holes 173 may have a diameter of 1 mm to 3mm in order to allow the air to smoothly flow while preventing the caught insects from escaping.

In addition, the ratio of the sum of the areas of the insect passing holes 121 to the sum of the areas of the mesh part holes 173 may be 1:1.2 to 1:3.0, and preferably, may be 1:1.8 to 1: 2.5. Within the ratio range, even if the amount of the insects caught and accumulated in the catching part 170 reaches 1/2 of the volume of the catching part 170, the flow of the air discharged to the outside of the insect trap 1000 is not hindered. In this case, preferably, the height of the bug zapper may be 8cm to 50 cm.

That is, the catching part 170 may allow the air current generated by the suction fan 150 to be effectively discharged to the outside of the insect trap 1000, and thus, the caught mosquitoes may be dried and killed in the catching part 170.

UV LED mounting portion 160

Referring to fig. 1 to 3, the UV LED mounting part 160 may be in a plate form. Specifically, the UV LED mounting part 160 may be formed in a shape and/or size similar to those of the body 110, and for example, when the body 110 is circular, the UV LED mounting part 160 may be formed in a circular plate shape having a size similar to those of the body 110.

Accordingly, the UV LED mounting part 160 is restricted such that the air flow generated by the suction fan 150 flows into the space formed between the UV LED mounting part 160 and the main body 110, thereby enabling the efficiency of generating the air flow flowing into the insect trap 1000 to be improved, and as a result, the rotation number of the suction fan 150 does not need to be unnecessarily excessively controlled, and thus the generation of noise can be minimized.

On the other hand, a holder 180 for supporting the UV LED mounting part 160 in a spaced manner may be disposed on the main body 110 so that insects do not flow into a space between the main body 110 and the UV LED mounting part 160, a UV LED module 161 may be attached to the UV LED mounting part 160, and a UV LED mounting part canopy 162 may be additionally installed.

In addition, the shape and number of the brackets 180 are not particularly limited, but the two brackets 180 may be attached in opposite directions from the viewpoint of stably supporting the UV LED mounting part 160 and minimizing an area in which a space into which insects flow is limited by the brackets 180.

The UV LED mounting part 160 may control the height of the bracket 180 such that the UV LED mounting part 160 is vertically spaced apart from the main body 110 by a distance of 1cm to 10cm, preferably 2cm to 5cm, if the distance is shorter than 2cm, the hole for the inflow of insects is too small, the insect catching efficiency may be low, and if the distance is longer than 5cm, the air current formed by means of the suction fan 150 may not be formed with sufficient strength, and the problem of the low insect catching efficiency may occur.

Therefore, if the insects are attracted by the ultraviolet rays and approach the insect trap 1000, the insects can flow into the space between the main body 110 and the LED mounting part 160 by the suction airflow generated by the suction fan 150, and are caught by the catching part 170 at the lower part of the air dust collecting part 130 by the insect passing part 120 and the suction fan 150.

Referring to fig. 3, the UV LED module 161 may be installed under the UV LED installation part 160, and as shown in fig. 3, after the UV LED installation part canopy 162 installed at the upper end of the UV LED installation part 160 in a detachable form is detached, the UV LED module 161 may be inserted into the lower part of the UV LED installation part 160 from the upper part thereof to attach the UV LED module 161. The UV LED module 161 attached to the UV LED mounting part 160 may be electrically connected to a power source.

In the insect trap 1000 according to an embodiment of the present invention, the UV LED module 161 may be attached to the UV LED mounting part 160 so as to irradiate light in a direction horizontal to the ground. When the insects stay at a height of about 1.5m from the ground for the longest time while flying, and thus the insect trap 1000 is installed at a height of about 1.5m from the ground, the insects are strongly stimulated by the light irradiated in a direction horizontal to the ground by the UV LED module 161, and can be effectively attracted to the insect trap 1000.

Further, as shown in fig. 3, a UV LED mounting portion canopy hook 163 is additionally mounted on the upper surface of the UV LED mounting portion canopy 162, so that the insect trap 1000 can be conveniently used by hanging it on a tree branch having a height of about 1.5m when used outdoors.

The UV LED mounting part 160 is formed in a manner corresponding to the UV LED module 161, and is additionally provided with a UV LED module cover for protecting the UV LED module 161, so that the phenomenon that the UV LED module 161 is damaged due to the approach of external dust or insects can be prevented, and preferably, the UV LED module cover is transparent.

The UV LED module cover is formed in various shapes, and thus functions as a lens for diffusing or condensing light emitted from the UV LED module 161 in a predetermined direction. As one example, the UV LED module cover may include glass, quartz (quartz), or the like. A polymer having good moldability, easy handling, and good durability as compared with glass, quartz, or the like may be used, but in a molecular structure, since the polymer exists around the atomic nucleus and absorbs light having a wavelength of 400nm or less (ultraviolet wavelength region) by electron cloud (electron cloud) having a resonance frequency corresponding to UV, not only light transmittance is significantly reduced, but also a material itself is degraded by ultraviolet rays, and thus, preferably, the polymer is not generally used as the UV LED module cover.

However, pmma (poly methyl methacrylate) having a monomer ratio higher by about 80% or more is mainly composed of carbon and hydrogen, so that electron cloud is thin and UV transmittance is high, and thus the UV LED module cover can be formed using such a material.

Further, a fluorine-based polymer which is a stable substance not reacting with ultraviolet rays may be used. As an example, since the fluorine-based polymer has a lower ultraviolet transmittance than quartz or PMMA, it is preferable to make the fluorine-based polymer have a relatively soft characteristic and a small thickness. That is, in order to use a fluorine-based polymer as the UV LED module cover, the ultraviolet transmittance should be considered, and the fluorine-based polymer has a lower ultraviolet transmittance than quartz or PMMA, and thus has a higher ultraviolet transmittance as the thickness is smaller, but if the thickness of the UV LED module cover is made thinner, the polymer may be easily broken even by a small impact due to brittleness, and thus it is preferable that the material itself is made of a soft and soft material so that the brittleness is reduced.

On the other hand, although not shown in fig. 3, the UV LED mounting part 160 may be attached or coated with a material capable of reflecting UV irradiated by the UV LED module 161 thereunder. The material capable of reflecting the UV is not particularly limited, and a material such as silver or aluminum may be attached, and a silver or aluminum film may be applied to the lower surface of the UV LED mounting portion 160, and various types of meandering or uneven patterns for scattering the irradiated light may be added.

In addition, referring to fig. 1 to 3, a UV LED mounting portion canopy 162 formed to be extended in a horizontal direction from the UV LED mounting portion 160 may be attached to the upper surface of the UV LED mounting portion 160. The form and material of the UV LED mounting portion canopy 162 are not particularly limited, and may be the same material and form as those of the UV LED mounting portion 160, and for example, when the UV LED mounting portion 160 is circular, the UV LED mounting portion canopy 162 may be formed to have a center the same as that of the UV LED mounting portion 160 and a longer diameter.

Preferably, the diameter of the UV LED mounting part canopy 162 may be formed to be longer by 3.5cm to 7cm than the diameter of the UV LED mounting part 160, when the portion of the UV LED mounting part canopy 162 having the diameter longer than the diameter of the UV LED mounting part 160 is shorter than 3.5cm, the air flow formed by means of the suction fan 150 may be dispersed without being concentrated on the side or the lower surface, and when the portion of the UV LED mounting part canopy 162 having the diameter longer than the diameter of the UV LED mounting part 160 is longer than 7cm, a problem of unnecessarily blocking the amount of light irradiated by the UV LED module 161 may occur. Specifically, the diameter of the UV LED mounting part canopy 162 may be formed to be longer than the diameter of the UV LED mounting part 160 by 3.5cm to 7cm in a range where the diameter of the UV LED mounting part 160 is 8cm to 20cm and the diameter of the UV LED mounting part canopy 162 is 10cm to 25 cm.

In the insect trap 1000 according to an embodiment of the present invention, when the diameters of the UV LED mounting part 160 and the UV LED mounting part canopy 162 are within the numerical range, the speed of the air flow generated by the suction fan 150 is set to 0.5m/s to 3m/s in the region formed by the 1 st region vertically extended downward from the UV LED mounting part canopy 162 and the 2 nd region horizontally extended from the main body 110, and thus the optimum wind speed at which mosquitoes flow into the insect trap 1000 while they stop flying can be formed.

On the other hand, as described above, the UV LED mounting part 160 is located at a distance of 2cm to 5cm from the main body 110, and at the same time, the diameter of the UV LED mounting part canopy 162 is controlled so that the air flow generated by the suction fan 150 is maintained without being affected by external wind or the like, enabling the insects attracted by the irradiated light to be stably sucked into the insect passage part 120.

UV LED modules

161, 261, 361

The

UV LED modules

161, 261, 361 may provide light having at least one wavelength of ultraviolet rays, visible rays, infrared rays, and preferably, may provide ultraviolet rays. Regarding the wavelengths for attracting insects, it has been reported that flies and rice planthoppers prefer light of wavelengths of about 340nm or about 575nm, and moths and mosquitoes prefer light of wavelengths of about 366 nm. In addition, it has been reported that other general pests relatively prefer light having a wavelength of about 340nm to 380 nm. As another example, regarding the wavelength of the visible ray region for attracting insects, the attracting activity of white, yellow, red, green, blue light to insects is disclosed in korean laid-open patent No. 2013-0049475 or korean laid-open patent No. 2014-0010493.

Preferably, the wavelength of light emitted from the

UV LED modules

161, 261, 361 may be 340nm to 390nm, and insects, particularly mosquitoes, are strongly attracted and, on the contrary, the harmfulness to the human body is low, and from this point, it is more preferable to control to irradiate light having a wavelength of about 365 nm.

The

UV LED modules

161, 261, 361 may include at least one or more cob (chip on board) type UV LED chips 165 or at least one or more UV LED packages attached to the support substrate 164, and the UV LED modules 161 may include a plurality of rows of the UV LED chips 165 or UV LED packages, and the UV LED chips 165 or the UV LED packages may be in a zigzag (zigzag) shape in order to suppress overheating of the support substrate 164.

The support substrate 164 may have a panel shape having a predetermined thickness, and may include a printed circuit board having an integrated circuit or a wiring therein. As an example, the support substrate 164 may be a printed circuit board having a circuit pattern in a region where the UV LED chip 165 is to be mounted, and the support substrate 164 may be made of a material such as metal, semiconductor, ceramic, or polymer.

Specifically, the

UV LED modules

161, 261, 361 may be formed by mounting the UV LED chips 165 on a long flat plate-shaped PCB. The UV LED chips 165 may be mounted in plurality, for example, 4 to 10, at intervals along the length direction of the PCB. A heat sink plate for dissipating heat generated from the UV LED chip 165 may be mounted on the other surface of the PCB, and terminals connected to a power supply terminal and supplying power to the PCB may be mounted at both ends of the

UV LED modules

161, 261, and 361.

The UV LED chip or UV LED package according to an embodiment of the present invention may be additionally mounted with a light guide plate, a diffusion sheet, or the like as needed to irradiate surface-emission light, preferably, point-emission light. The device for irradiating the point luminous rays has advantages in that a manufacturing process is simple and an attracting effect of insects is high, compared with the device for irradiating the surface luminous rays.

A plurality of UV LED chips for irradiating the spot light emission light may be attached to the support substrate, specifically, 2 to 10, and preferably 3 to 6.

The point emitting light source may be spaced apart from the other point emitting light sources by 2mm to 50mm, preferably, by 3mm to 30mm, and more preferably, by 3mm to 20 mm. When the interval between the plurality of point-emission light sources is less than 2mm, the durability of the UV LED chip or UV LED package may deteriorate as the heat generated from the UV LED chip or UV LED package excessively increases, and when the interval exceeds 50mm, the attraction efficiency may decrease.

The

UV LED modules

161, 261, 361 may be manufactured such that a light output reaches 800mW to 1500mW when an input voltage is 10V to 15V and an input current is 75mA to 100 mA. In addition, the UV LED module has a light output of 110mW at a current of 75mA or 700mW at a current of 500 mA. Within the above numerical range, the insect attractant can effectively attract insects with 365nm wavelength light, and at the same time, can irradiate ultraviolet rays with wavelength and intensity harmless to human body, and minimize waste of electric power.

The

UV LED modules

161, 261, and 361 may be UV LED chips 165 or UV LED packages attached to one surface of the support substrate 164, and may be arranged on the support substrate 164 without overlapping with the UV LED chips 165 or UV LED packages attached to the other surface, and a specific form is not particularly limited, and may be a form of arranging a plurality of rows or a zigzag (zigzag) form. Accordingly, the insect trap 1000 according to an embodiment of the present invention can minimize power consumption while greatly expanding a light irradiation range, effectively discharge heat generated from the UV LED chips 165, and improve durability of the

UV LED modules

161, 261, 361.

The electric power supplied to the

UV LED modules

161, 261, 361 generates heat in the UV LED chip 165 while being converted into light and heat energy forms, and thus the temperature measured in a space within a distance of the

UV LED modules

161, 261, 3611 cm may be 50 to 60 ℃. Insects, particularly mosquitoes, are strongly attracted by a temperature of about 38 to 40 c, which is similar to the body temperature, and thus, in addition to the attraction effect generated by the

UV LED modules

161, 261, 361, the insects can be strongly attracted to the insect trap 1000 by means of heat generated from the

UV LED modules

161, 261, 361.

Accordingly, the insect trap 1000 according to an embodiment of the present invention uses the

UV LED modules

161, 261, 361 manufactured to have a light output of 800mW to 2000mW, preferably 1000mW to 1500mW at an input voltage of 10V to 15VV and an input current of 75mA to 85mA, and the UV LED chip 165 or the UV LED package attached to one side of the support substrate 164 is arranged on the support substrate 164 without overlapping with the UV LED chip 165 or the UV LED package attached to the other side, so that it is possible to minimize the consumption of electric power, irradiate light harmless to the human body and having high insect-attracting efficiency, and simultaneously generate heat, so as to form a temperature having a high insect-attracting effect at the periphery of the insect trap 1000.

[ second embodiment ]

In the second embodiment of the insect trap 2000 (not shown) according to the embodiment of the present invention, the configuration of the first embodiment can be used in addition to the installation of the photocatalytic filter unit, as compared with the first embodiment, and the configuration of the photocatalytic filter unit will be described in detail below.

The installation position of the photocatalytic filter section is not particularly limited as long as the UV emitted from the UV LED module 161 can be irradiated in the insect trap. Preferably, the photocatalytic filter portion may be mounted under the UV LED mounting portion 160 and/or the UV LED mounting portion canopy 162.

Preferably, the photocatalytic filter unit is not projected from the insect trap but is embedded. Specifically, in the case of the side-embedded type in which the side surface can be brought into contact with the airflow generated by the insect trap 1000, the space inside the insect trap 1000 can be efficiently configured without impairing the inflow of the insects into the insect trap 1000 and the inflow of the air.

The photocatalytic filter unit can generate a deodorizing effect by catalyzing UV irradiated from the UV LED module 161 under the UV LED mounting part 160.

The photocatalytic filter unit may be in the form of a photocatalyst layer coated on a non-limiting frame, and may be in the form of a photocatalyst layer coated on a porous material such as metal foam (metal foam) or carbon foam (carbon foam), or may be in the form of a photocatalyst layer coated in ceramic.

The photocatalyst layer added to the photocatalytic filter portion may be selected from titanium oxide (TiO)₂) Silicon oxide (SiO)₂) Zinc oxide (ZnO), zirconium oxide (ZrO)₂) Tin oxide (SnO)₂) Cerium oxide (CeO)₂) Tungsten oxide (WO)₃) Iron oxide (Fe)₂O₃) Zinc sulfide (ZnS), cadmium sulfide (CdS), and strontium titanate (SrTiO)₃) One or a combination of the above groups, preferably, may be made of titanium oxide (TiO)₂) A coating layer is provided.

By the radicals generated by the photocatalytic filter unit, organic substances in the air around the photocatalytic filter unit are decomposed, so that an effect of purifying the air around the insect trap can be generated.

The photocatalyst layer can generate CO having a high attracting effect to insects, particularly mosquitoes, in addition to a deodorizing effect₂. That is, a photocatalytic filter unit capable of generating carbon dioxide using UV irradiated by the UV LED module 161 as a catalyst may be attached to the lower surface of the UV LED mounting part 160, and preferably, a photocatalytic filter unit capable of generating carbon dioxide using UV irradiated by the UV LED module 161 as a catalyst may be attached to the lower surface of the UV LED mounting part 160 and/or the UV LED mounting part canopy 162.

Specifically, if light inducing a photocatalytic reaction is irradiated from the UV LED module 161 to the photocatalyst layer, radicals having strong reducibility can be generated by means of a known photocatalytic reaction. By means of the radicals, the organic components around the photocatalyst layer are decomposed, and carbon dioxide can be generated. The carbon dioxide is considered to be a gas that attracts insects, particularly mosquitoes. As an example, the light inducing the photocatalytic reaction may be ultraviolet light of a wavelength band of about 200nm to 400 nm. That is, although the light that induces the photocatalytic reaction irradiates the photocatalyst layer to generate radicals, the light itself attracts insects as described above, and the wavelength can be selected in consideration of both the photocatalytic reaction and the direct attraction of insects.

In addition, in order to increase the production efficiency of carbon dioxide, an attractant substance such as lactic acid, an amino acid, sodium chloride, uric acid, ammonia, or a protein decomposition substance may be provided in the photocatalytic filter section. The method of providing the attraction substance is not particularly limited, and as an example, a method of coating the photocatalyst layer in the photocatalyst filter part with an attraction substance or periodically or non-periodically spraying the photocatalyst layer may be applied. The increased carbon dioxide concentration thus makes it possible to increase the efficiency of insect attraction.

That is, the insect trap 2000 of the present invention can greatly improve the efficiency of attracting insects, particularly mosquitoes, by using not only light and heat generated by the UV LED modules 161 as an attracting element of the insects but also carbon dioxide gas as an attracting element.

[ third embodiment ]

The insect trap 3000 of an embodiment of the present invention may further include an insecticidal UV LED mounting part 190 to which an insecticidal UV LED module 191 is attached, and as shown in fig. 16, the wavelength of light emitted from the insecticidal UV LED module 191 may be 200nm to 300 nm.

Since the third embodiment may use the configuration of the first embodiment in addition to the pesticidal UV LED mounting portion 190 to which the pesticidal UV LED module 191 is added, only the pesticidal UV LED mounting portion 190 to which the pesticidal UV LED module 191 is added will be described in detail below.

The attachment position of the insecticidal UV LED mounting portion 190 is not particularly limited, and it is preferable that the insecticidal UV LED mounting portion is attached to the catching portion 170 where the caught insects stay for the longest time.

That is, the insect trap 3000 may be configured to kill insects caught in the catching part 170 in a short time by additionally installing the UV LED module 191, in addition to a method of drying and killing the insects caught in the catching part, particularly, insects, and may use UVC having excellent energy efficiency and insecticidal efficiency, and more particularly, UVC having a wavelength of 200nm to 300 nm.

In addition, the insecticidal UV LED module 191 controls to generate electric energy of 1KJ or more when the voltage is 12V to 20V and the input current is 200mA to 280mA, thereby enabling the trapped insects to be insecticidal in a short time with small energy.

[ fourth embodiment ]

A fourth embodiment of an insect trap 4000 (not shown) according to an embodiment of the present invention may use the configuration of the first embodiment in addition to the configuration in which the UV LED module 161 performs dimming control, and thus only the dimming control will be described in detail below.

The fourth embodiment proceeds from the basic concept that the on/off, intensity, period, etc. of the induction light are varied to release the induction light as compared with the release of the induction light of a given intensity, which can further improve the efficiency of insect catching.

The term "light control" used in the present invention is a concept covering all control operations for controlling the driving of the light emitting section, including not only a concept for controlling the light output of the light emitting section but also a concept for covering all of the on/off of the light emitting section and the light emitting period of the light emitting section.

Fig. 10 is a block diagram illustrating an electrical connection relationship between a plurality of components in the insect trap of the first embodiment of the present invention. In addition, fig. 11 to 13 are waveform diagrams showing a relationship of the LED driving current or the driving voltage according to the dimming level according to the first embodiment of the present invention. Referring now to figures 10 to 13, the circuit configuration and features of an insect trap 4000 according to a first embodiment of the invention will be observed.

First, as shown in fig. 10, the insect trap 4000 according to the first embodiment of the present invention may include a power supply unit 40, a 1 st light emitting unit 10, a 1 st dimming control unit 11, and a 1 st dimmer 12, as viewed from a circuit point of view.

As shown in fig. 10, the power supply unit 40 rectifies and stabilizes an ac voltage (i.e., an input voltage (Vac)) input from an ac power supply, generates a drive voltage (Vp), and outputs the generated drive voltage (Vp) to the 1 st light emitting unit 10 and the 1 st light control unit 11. As such a power supply unit 40, one of various power supply circuits such as a full-wave rectifier circuit, a half-wave rectifier circuit, and an SMPS can be used. However, for convenience of explanation and understanding, an embodiment configured such that the power supply unit 40 supplies a stabilized driving voltage (Vp) in a dc mode, that is, an embodiment of a dc driving method will be described below as a reference. However, it is obvious to those skilled in the art that the present invention is not limited to such a direct current driving method, and can be applied to various kinds of insect traps including an alternating current driving method.

On the other hand, as described above, the 1 st light emitting portion 10 may include a plurality of light emitting diodes or light emitting diode packages. Since the description is made with reference to the embodiment in which the driving is performed by the dc driving method, the 1 st light emitting unit 10 has one forward voltage level as a whole, and performs the driving control integrally. However, in the embodiment in which the driving is performed by the ac driving method, the 1 st light emitting unit 10 is configured by a plurality of LED groups, and can sequentially emit light and sequentially turn off under the control of the 1 st dimming control unit 11.

The 1 st dimmer 12 is configured to receive an input of a 1 st dimming level for performing dimming control of the 1 st light emitting unit 10. In addition, the 1 st dimmer 12 may be configured to function as an interface for programming a dimming level selection algorithm, which will be described later, according to a difference in configuration embodiment. Such a 1 st dimmer 12 is not an essential component, and may be optionally included or excluded in the insect trap 4000.

The 1 st dimming control unit 11 is configured to perform dimming control of the 1 st light emitting unit 10 according to the 1 st dimming level. The 1 st dimming control unit 11 may be configured to perform dimming control according to one dimming method among various dimming methods including, for example, an LED driving current control method, an LED driving voltage control method, a PWM control method, a phase control (phase cut) method, and the like. On the other hand, the 1 st dimming level means a dimming level set for the 1 st light emitting unit 10, the 2 nd dimming level means a dimming level set for the 2 nd light emitting unit 20, and the 3 rd dimming level means a dimming level set for the 3 rd light emitting unit 30.

FIG. 11 illustrates an LED drive current (I) of an embodiment constructed as follows_LED) A waveform that allows the 1 st dimming control part 11 to control the LED drive current (I) flowing through the 1 st light emitting part 10_LED) And performs dimming control. The dimming control in the LED drive current control method is based on the light output of the LED and the LED drive current (I)_LED) Proportional characteristic, the 1 st dimming control part 11 controls the LED driving current (I) based on the 1 st dimming level_LED) Thereby performing dimming control. For example, when the dimming level is 80%, the LED driving current (I) is set at the dimming level of 100%_LED) 80% of the value, controlling the LED drive current (I)_LED) Thereby, dimming control according to the 80% dimming level can be performed. Fig. 11 illustrates a waveform diagram in which the 1 st dimming level is 50% during the time interval (t0 to t1), and therefore, the LED driving current (I)_LED) The current level is controlled to 50% of the maximum LED drive current, and at the time point (t1), the 1 st dimming level is changed to 100%, and the LED drive current (I)_LED) The control is 100% current level of the maximum LED drive current. Due to LED drive current (I)_LED) The current level of (1) varies according to the dimming level, and therefore the light output of the 1 st light emitting unit 10 varies accordingly.

Fig. 12 illustrates a driving voltage (Vp) waveform of an embodiment configured such that the 1 st dimming control part 11 performs the PWM control of the driving voltage (Vp) applied to the 1 st light emitting part 10 according to the PWM (pulse width modulation) signal generated based on the 1 st dimming level, thereby performing the dimming control. Fig. 12 illustrates a waveform diagram in which the 1 st dimming level is 50% during a time interval (t0 to t2), and accordingly, the duty ratio of the PWM signal is 50%, and at a time point (t2), the 1 st dimming level is changed to 70%, and the duty ratio of the PWM signal is controlled to 70%. The duty ratio of the driving voltage (Vp) applied to the 1 st light emitting part 10 is changed according to the dimming level, and thereby the light output of the 1 st light emitting part 10 is changed.

Fig. 13 illustrates a driving voltage (Vp) waveform of an embodiment configured such that the 1 st dimming control part 11 controls a voltage level of the driving voltage (Vp) applied to the 1 st light emitting part 10, thereby performing dimming control. The dimming control in the LED driving voltage control method is performed by controlling the voltage level of the driving voltage (Vp) applied to the 1 st light emitting unit 10 based on the 1 st dimming level based on the characteristic that the light output of the LED is proportional to the driving voltage (Vp). Fig. 13 illustrates a waveform diagram in which the 1 st dimming level is 100% during a time interval (t0 to t3), and accordingly, the LED driving voltage (Vp) is controlled to the 100% voltage level of the maximum LED driving voltage, and at a time point (t3), the 1 st dimming level is changed to 60% and the LED driving voltage (Vp) is controlled to the 60% voltage level of the maximum LED driving voltage. The voltage level of the LED driving voltage (Vp) changes according to the dimming level, and the light output of the 1 st light emitting unit 10 changes accordingly.

On the other hand, although it has been described above that the 1 st dimming control unit 11 performs dimming control using only one dimming method, it is also obvious to those skilled in the art that a plurality of dimming methods among the various dimming methods described above or apparent to those skilled in the art may be applied together as necessary.

The 1 st dimming control unit 11 may be configured to change the dimming level for a predetermined period of time and execute the dimming control of the 1 st light emitting unit 10. In one example, the 1 st dimming control part 11 may be configured to randomly select a dimming level every 10 seconds, for example, and control the light emission of the 1 st light emitting part 10 for 10 seconds according to the selected dimming level. In another example, the 1 st dimming control unit 11 may be configured to select a dimming level according to a preset dimming level selection algorithm every 10 seconds, for example, and control the light emission of the 1 st light emitting unit 10 for 10 seconds according to the selected dimming level. For example, the dimming level selection algorithm may be configured to increase the dimming level by 10% every 10 seconds from a 10% dimming level to a 100% dimming level, and to decrease the dimming level by 10% every 10 seconds to a 10% dimming level after reaching the 100% dimming level. Of course, this is merely an example, and various dimming level selection algorithms may be configured and utilized as needed, as will be apparent to those skilled in the art.

Fig. 14 is a block diagram showing an electrical connection relationship between a plurality of components of the UV LED module according to an embodiment of the present invention. In another example shown in fig. 14, when the 2 nd light emitting part 20 is configured differently from the 1 st light emitting part 10, the insect trap may further include another 2 nd dimming control part 21 for controlling the driving of the 2 nd light emitting part 20. In one example, the 2 nd light emitting part 20 may be configured to emit light of a different wavelength than the 1 st light emitting part 10. That is, the 1 st light emitting part 10 may be configured to emit the 1 st wavelength of light for attracting the 1 st kind of insects, and the 2 nd light emitting part 20 may be configured to emit the 2 nd wavelength of light for attracting the 2 nd kind of insects. In another example, the 2 nd light emitting part 20 may include an LED chip or an LED package having a different configuration from the 1 st light emitting part 10. When the 2 nd light emitting part 20 is configured differently from the 1 st light emitting part 10, the 2 nd light emitting part 20 may have a different physical property (e.g., a forward voltage level, etc.) from the 1 st light emitting part 10, and thus be configured to perform dimming control by means of the additional 2 nd dimming control part 21. Alternatively, even in the case where the 2 nd light emitting unit 20 is configured identically to the 1 st light emitting unit 10, when the dimming control of the 1 st light emitting unit 10 and the dimming control of the 2 nd light emitting unit 20 are to be executed independently of each other, the 2 nd light emitting unit 20 is configured to be subjected to the dimming control by means of the additional 2 nd dimming control unit 21.

The 2 nd dimming control part 21 is configured to perform dimming control of the 2 nd light emitting part 20 according to the 2 nd dimming level. The 2 nd dimming control part 21 may be configured to perform dimming control according to one dimming method among various dimming methods including, for example, an LED driving current control method, an LED driving voltage control method, a PWM control method, a phase control (phase cut) method, and the like, similarly to the 1 st dimming control part 11 as described above. In addition, the 2 nd dimmer 22 may be configured to accept an input of a 2 nd dimming level for performing dimming control of the 2 nd light emitting part 20, and is selectively included in the insect trap 4000, similar to the 1 st dimmer 12 described above.

Fig. 15 is a block diagram showing an electrical connection relationship between a plurality of components of the UV LED module according to an embodiment of the present invention. As shown in fig. 15, the 3 rd dimming control part 31 is configured to perform dimming control of the 3 rd light emitting part 30 according to the 3 rd dimming level. The 3 rd dimming control part 31 may be configured to perform dimming control according to one dimming method among various dimming methods including, for example, an LED driving current control method, an LED driving voltage control method, a PWM control method, a phase control (phase cut) method, and the like, similarly to the 1 st dimming control part 11 and the 2 nd dimming control part 21 described above. In addition, the 3 rd dimmer 32 may be configured to accept an input of a 3 rd dimming level for performing dimming control of the 3 rd light emitting part 30, and may be selectively included in the insect trap, similar to the 1 st dimmer 12 and the 2 nd dimmer 22 described above.
