Description

INSECT TRAP

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trapper, and more particularly, to a trapper that uses ultraviolet guided light to attract a pest.

Recently, pests have been increasing due to climatic and social influences such as global warming and eco-friendly policies. In addition to damaging crops and livestock, pests can also affect humans by moving pathogens such as malaria, dengue fever, and Japanese encephalitis. In particular, recent studies on mosquito insecticide-related methods have been actively conducted due to the fear spread of zika virus (ZIKV) infection.

In connection with the insecticidal method, conventionally, a chemical control method using an insecticide, a biological control method using a loach or the like, a physical control method in which a pest is attracted to a pylorus or the like by a pyloric or the like and then a high voltage is applied to the pest, And an environmental control method to improve the surrounding environment so that the larvae can not live on. However, in the case of the chemical control method, the second pollution problem arises, and the biological control method or the environmental control method may take a relatively large expense, the processing time and effort, and in the case of the physical control method using the insecticide or trapper, There is a problem that the convenience of the user is deteriorated or there is a risk that the high voltage device is accompanied.

On the other hand, the UV light source is used for various purposes such as medical purpose such as sterilization and disinfection, analysis purpose using the irradiated UV light, industrial purpose of UV hardening, cosmetic purpose of UV tanning, Conventional UV light source lamps used as such UV light sources include mercury lamps, excimer lamps, and deuterium lamps. However, all of these conventional lamps have a problem of power consumption, heat generation, short life span, and environmental pollution due to toxic gas filling the interior.

In order to solve the problems of the conventional UV light source lamps described above, UV LEDs are preferred. The UV LED has the advantages of low power consumption and no environmental pollution problem. Accordingly, there have been studies on a trap that collects pests attracted by attracting light using a UV LED by a suction fan.

However, in the case of a capturing device that attracts pests using a conventionally used UV LED, there is an inconvenience that the user feels the operation of the UV LED due to the visible light emitted with the UV in the UV LED. The UV LED has a peak wavelength in the ultraviolet region, but includes the blue wavelength region in the visible region, so that the user can recognize the operation of the UV LED. Accordingly, there is a problem in that the user can not take a good night's sleep due to the visible light emitted from the UV LED of the trapper while operating the attraction light emission at night, and when the user cuts off the attraction light emission to take a good night's sleep, There was a problem of getting worse.

Also, there is a problem that the user can easily feel fatigue due to the blue light emitted from the trapper.

The object of the present invention is to provide a trapper capable of maintaining the attracting efficiency of the insect highly and at the same time improving the usability of the user. In particular, And to provide a catcher capable of blocking emission.

According to embodiments of the present invention, there is provided a body having an insect inlet; An attracting light source including a light emitting chip for generating a visible light with ultraviolet rays for attracting insects into the body; And an optical filter for transmitting ultraviolet light among the light generated in the light emitting chip and blocking at least a part of the visible light.

According to the embodiments of the present invention, by using an optical filter that transmits ultraviolet rays and blocks visible light, ultraviolet rays can be used to keep the attracting efficiency of the insect highly high and to eliminate the inconvenience of the user by visible light. Can be provided.

<According to the First Embodiment Catcher (100) &gt;

Fig. 1 is a perspective view showing a catcher according to a first embodiment of the present invention, Fig. 2 is an exploded perspective view of Fig. 1, and Fig. 3 is a side view of Fig.

1 to 3, the catcher 100 is configured to attract and collect insects with ultraviolet rays, and includes a body 110; A suction fan 112 mounted inside the body 110; A collecting part 120 disposed below the suction fan 112; And an objective light source cover unit 130 coupled to the support 140 disposed on the body 110 and having the attracted light source 10 mounted thereon.

body (110)

The body 110 can be designed in consideration of the rotating direction of the suction fan 112 so that the direction of the airflow caused by the rotation of the suction fan 112 is formed into the collecting part 120 at the insect inflow port 110a.

The shape of the insect inflow port 110a provided in the body 110 is not particularly limited and may be circular or polygonal in that the area through which insects sucked into the airflow generated by the suction fan 112 can be expanded It can be a polygon. The material of the body 110 is not particularly limited, but may be made of a common plastic material so that it can be used indoors or outdoors for a long time and at the same time, the manufacturing cost is not increased greatly. The body 110 may have a structure that is opened up and down so that air can pass vertically.

1 to 3, the body 110 is provided with an insect inflow port 110a, which is a space defined by the top surface 111 of the body 110 such that the upper surface of the body 110 is opened, ), And the shape of the flow path can be defined such that the suction air flow by the suction fan 112 can be formed in a fluid-mechanically efficient manner. For example, the body 110 extends in a circular arc in a downward direction from at least one side of the first region 111a and the first region 111a, which are inclined in a direction toward the lower portion from the insect inflow port 110a A third region 111c having a second region 111b formed thereon and inclined substantially linearly in a downward direction in the first region 111a and the second region 111b and a collecting section 120 in a direction substantially perpendicular to the first region 111d.

At this time, in the flow path, the width 111f defined by the fourth region 111d is formed narrower than the width 111e defined by the third region 111c, so that the fluid flows from the insect inlet 110a to the trapping portion (120). &Lt; / RTI &gt;

Suction fan (112)

1 to 3, the suction fan 112 may be mounted on the upper part of the collecting part 120 in the body 110. [

The suction fan 112 may be a cross fan. For example, a plurality of vanes may be arranged in a columnar shape. The suction fan 112 may be rotated by a driving means such as a motor, not shown, Or a curved shape with a certain curvature.

The suction fan 112 is installed to be substantially horizontal with respect to the insect inflow port 110a so as to suck air together with insects from the insect inflow port 110a during the rotation of the suction fan 112 and to send the air to the collecting unit 120 can do.

The suction fan 112 can be separated from the inner wall of the body 110 by 1 to 50 mm and the suction fan 112 can minimize the generation of noise while ensuring the trapping space of insects within the range, have. At this time, the number of fan blades of the suction fan 112 is 20 to 40, and the rotation speed of the suction fan 112 may be 2000 rpm to 3500 rpm.

More specifically, it is preferable that the suction fan 112 controls the insect to flow into the lower portion of the suction fan 112 without sticking to the suction fan 112. In the case of a catcher that collects insects using a conventional suction fan, the insects stick to the fan blades, so that the rotation radius of the suction fan is not uniform, resulting in poor durability of the motor or noise. However, when the rotational speed of the suction fan is reduced in order to prevent the insects from sticking to the fan blades, there is a problem that the collection efficiency of insects adjacent to the catcher is remarkably reduced. In other words, the insect tends to stop the flight at an air velocity of 0.8 m / s or more, but when the wind speed is too high, the insect attempts to escape from the air flow. Therefore, the inventors of the present invention prevent insects from sticking to the suction fan 112 The mosquito stops the flight and is collected by the suction airflow generated in the suction fan 112. [

For this, the number of the fan blades is 20 to 40, for example, 24 to 36, and the rotation speed of the suction fan 112 may be 2000 rpm to 3500 rpm, for example, 2100 rpm to 3000 rpm. If the number of the fan blades is less than 20 or the rotation speed of the suction fan 112 is less than 2000 rpm, the mosquito collection effect may be reduced. If the number of the fan blades exceeds 40 or the rotation speed of the suction fan 112 There is a problem that the mosquito corpse is excessively attached to the suction fan 112 or the noise is increased to 38 dBA or more.

The catcher 100 according to the first embodiment has a structure in which the suction fan 112 is disposed at a height of 20 mm from the upper surface 111 of the body in a region having an area equal to four times the area of the insect inflow port 110a on the basis of the same center point as the insect inflow port 110a. The speed of the airflow formed by the air flow passage may be 0.5 m / s to 3 m / s, for example, 0.8 m / s to 2.5 m / s. Insects, especially mosquitoes, tend to stop flying at a wind speed of more than 0.8 m / s and flow to the air stream, so that the efficiency of insects being sucked into the trap 110 may be low at airflow velocities below 0.5 m / s, / s, insects may attempt to escape or excessively loud noise may be generated.

Accordingly, the inventors of the present invention have found that by controlling the rotational speed of the suction fan 112, the number of fan blades, and the speed of the airflow formed by the suction fan 112, the insects do not stick to the suction fan 112, And can be collected in the collecting part 120 with high efficiency, and noise generation by the suction fan 112 can be suppressed.

Collection section (120)

The collecting part 120 is disposed at the bottom of the body 110, and can be of a removable type, for example.

The collecting part 120 may include a collecting part mesh part 121 through which the air introduced by the suction fan 112 is discharged to the outside. The trap portion mesh portion 121 preferably has a hole diameter of 1 mm to 3 mm, and the air flow can be controlled smoothly while the trapped insects can not escape within the diameter range.

For example, one to ten collecting part mesh parts 121 may be provided in the collecting part 120, and may be, for example, two to eight. In this case, 300 to 700, for example, 400 to 600 may be provided.

That is, the collecting unit 120 allows the airflow generated by the suction fan 112 to be effectively discharged to the outside of the catcher 100, so that the mosquitoes collected in the collecting unit 120 can be quickly dried.

In addition, the collecting unit 120 may include at least one surface transparent material so that the user can confirm the number or type of insects collected in the collecting unit 120.

Manned light source The cover portion (130)

1 to 3, the attracted light source cover unit 130 can be installed on the body 110 via the support base 140, and the attracted light source 10 can be detached from the attracted light source cover unit 130 And can be mounted on the attracting light source cover unit 130 so as to be able to be detached, and at least a part thereof can be provided with a transparent part.

The attracted light source cover 130 may be formed into various shapes and may serve as a lens for diffusing light emitted from the attracted light source 10 or for converging the light in a predetermined direction, for example. For example, the attracting light source cover 130 may include glass, quartz, poly methyl methacrylate (PMMA), or the like.

Also, the attracted light source cover unit 130 is coupled to the supporter 140 so as to be rotatable so that the user can control the direction of the light emitted from the attracted light source 10 according to circumstances.

The manned light source (10)

The attracting light source 10 may provide light having a wavelength of at least one of ultraviolet rays, visible rays, and infrared rays, and may provide ultraviolet rays, for example. Regarding the wavelengths to which the insects are attracted, it is reported that they prefer light at a wavelength of about 340 nm or about 575 nm in the case of flies and butterflies and prefer light at a wavelength of about 366 nm in the case of moths and mosquitoes. It has also been reported that, in the case of other common pests, relatively light of wavelengths of about 340 nm to 380 nm is preferred.

For example, the wavelength of the light emitted from the attracted light source 10 may be between 340 nm and 390 nm, and light of a wavelength of about 365 nm in terms of low harmfulness to the human body, Is controlled to be irradiated.

However, even if a UV-LED light emitting chip having a small half width is applied to the attracted light source 10, visible light can be emitted because the emission spectrum of the UV-LED is distributed over a wide wavelength range. In particular, light of a blue wavelength close to ultraviolet light can be emitted more strongly than light in another visible light region. It is necessary to prevent visible light, for example blue light, from being emitted to the outside of the trapper 100 in order to increase the convenience of the user while maintaining the attracting efficiency of the insect high, and will be described later.

On the other hand, the attracting light source 10 may include at least one chip on board (COB) type light emitting chip mounted on a supporting substrate, or may include at least one UV LED package having a light emitting chip mounted thereon. A plurality of light emitting chips or UV LED packages may be arranged in a plurality of rows on a supporting substrate and the light emitting chips or the UV LED packages may be arranged in a zigzag form to suppress the overheating of the supporting substrate have.

The supporting substrate may have a panel shape having a predetermined thickness, and may include a printed circuit board having an integrated circuit or wiring therein. For example, the support substrate may be a printed circuit board having a circuit pattern in an area where the light emitting chip is to be mounted, and the support substrate may be made of a metal, a semiconductor, a ceramic, a polymer, or the like.

For example, the attracted light source 10 may be a form in which the light emitting chip is mounted on a PCB having a long flat plate shape. The light emitting chips may be spaced apart from one another along the longitudinal direction of the PCB, for example, four to ten. A heat dissipating fin for dissipating heat generated from the light emitting chip may be provided on the other surface of the PCB, and terminals for supplying power to the PCB may be provided at both ends of the attracting light source 10 by connecting to a power supply terminal.

&Lt; &lt; Catcher (200)

FIG. 4 is a perspective view showing a catcher according to a second embodiment of the present invention, and FIG. 5 is a sectional view of FIG.

The catcher 200 according to the second embodiment includes a body 210, a suction fan 212 disposed in the body 210, an insect inlet 210a disposed on the body 210 and allowing insects to pass therethrough, An attracted light source cover unit 230 disposed above the body 210 and capable of mounting the attracted light source 20 and a collecting unit 220 disposed below the body 210 and collecting insects. Each configuration will be described below.

body (210)

Although the shape of the body 210 is not particularly limited, the body 210 may be cylindrical in that the suction fan 212 is mounted therein. For example, the body 210 may have a convex jar shape to secure an internal space, It is possible to secure a space through which electric wiring for supplying electric power to the motor 213 or the lower light source 214 passes. The material is not particularly limited, but may be made of a commonly used plastic material so that it can be used indoors or outdoors for a long time and at the same time the manufacturing cost is not increased greatly. The body 210 has a structure that is opened up and down so that air can pass vertically.

Referring to FIG. 4, insect inlet 210a may optionally include a plurality of holes through which insects may pass. The plurality of holes are not limited in shape and can be formed by a circular member and a radial member or can be formed by a series of circular members and the size of the plurality of holes Can be adjusted. On the other hand, when the insect inflow port 210a has the plurality of holes as a series of circular members as shown in Fig. 4, the size of the plurality of holes can be effectively controlled with a low manufacturing cost.

In the case of a trapper that collects insects using a conventional suction fan, insects such as butterflies, dragonflies, and flies having a larger volume than the mosquitoes are trapped together, so that the exchange period of the trapping part 220 is quick, There was a problem of harvesting the ecosystem. In addition, insects having a large volume stick to the suction fan 212, shortening the life of the motor 213 and generating noise in the suction fan 212. Accordingly, the inventors of the present invention have economically produced insect inflow ports 210a while controlling the size of the plurality of holes so that the catcher 200 can selectively suck insects.

The insect inlet 210a referred to herein may refer to a space defined by the body top surface 211 or to a space defined by a separate member provided between or above the body top surface 211 .

The plurality of holes may have a diameter of 0.5 cm to 2 cm, preferably 0.8 cm to 1.5 cm, or the area of one of the plurality of holes may be controlled to be 100 mm 2 to 225 mm 2. Therefore, insects, particularly mosquitoes, are selectively passed, while insects having a large body size such as butterflies, dragonflies, and flies are prevented from being trapped in the catcher 200, so that the durability of the motor 213 becomes poor, 212 can be reduced.

It is also preferable that the suction fan 212 controls the insect to flow into the lower portion of the suction fan 212 without sticking to the suction fan 212. In the case of a catcher that collects insects by using a conventional suction fan, insects stick to the fan blade and the rotation radius of the suction fan 212 becomes uneven. As a result, the durability of the motor 213 becomes poor, There was a problem that occurred. However, when the rotational speed of the suction fan 212 is reduced in order to prevent insects from sticking to the fan blades, there is a problem that the collection efficiency of insects adjacent to the catcher is remarkably reduced. In other words, the insect tends to stop the flight at an air velocity of 0.8 m / s or more, but when the wind speed is too high, the insect attempts to escape from the air current. Thus, the inventors of the present invention have found that insects do not stick to the fan wing, The flight was stopped and the catcher 200 to be caught by the suction airflow generated in the suction fan 212 was manufactured.

For this, the number of the fan blades is 2 to 7, preferably 3 or 4, and the rotation speed of the suction fan 212 may be 1800 rpm to 3100 rpm, preferably 2000 rpm to 2800 rpm. If the number of the fan blades is less than 2 or the rotation speed of the suction fan 212 is less than 1800 rpm, the collecting effect of the mosquito may be reduced. If the number of the fan blades is more than 7 or the rotation of the suction fan 212 If the speed exceeds 3100 rpm, there is a problem that the mosquito corpse sticks too much to the suction fan 212 or the noise rises to 38 dBA or more.

In addition, the fan blades may be curved with a constant or non-constant curvature, and the fan blades of a curved shape may have a height difference between the lowermost stage and the uppermost stage of 5 mm to 50 mm . On the other hand, the suction fan 212 may have a diameter of 50 mm to 120 mm, and preferably 70 mm to 100 mm. In addition, the shortest distance between the suction fan 212 and the inner wall of the body 210 is controlled to 1 mm to 5 mm, thereby minimizing noise caused by the suction fan 212 and effectively forming an intake air flow.

The catcher 200 also includes a motor 213 mounted below the insect inflow port 210a and a suction fan 212 mounted below the motor 213 so that the motor 213 and the suction fan 212 It is possible to remarkably reduce the noise, and preferably to be controlled to be less than 38 dB. Meanwhile, the noise can be measured using a noise measuring device (CENTER 320, TESTO) at a distance of 1.5 m horizontally from the catcher 200 under a condition of a noise of 29.8 dBA.

Collection section (220)

4 and 5, the collecting part 220 may include a collecting part side opening 221 for discharging the air introduced by the suction fan 212 to the outside.

At this time, the ratio of the total sum of the plurality of hole areas to the total sum of the area of the collecting part side surface 221 may be 1: 0.8 to 1: 3.0, preferably 1: 0.8 to 1: 2.0. Even if insects are trapped up to half of the volume of the trapping unit 220 within the above range, the flow of air discharged outside the trapping unit 200 may not be inhibited.

That is, the collecting unit 220 can cause the airflow generated by the suction fan 212 to be effectively discharged to the outside of the catcher 200, and thus the mosquitoes trapped in the collecting unit 220 can be killed.

In addition, the collecting part side surface 221 can be a slit shape or a mesh shape.

Manned light source The cover portion (230) and the roof (250)

4 and 5, the catcher 200 includes a roof 250 supported apart from the body 210 by a support 240 and an attracted light source cover unit 230 disposed below the roof 250 .

Although the shape and the number of the support rods 240 are not particularly limited, it is preferable that the support rods 240 ) Can be mounted in opposite directions.

The roof 250 can control the length of the support 240 so that the roof 250 is vertically spaced from the body 210 by a distance of 1 cm to 8 cm and preferably 2 cm to 5 cm, And the distance that the roof 250 is vertically spaced from the body 210 may be the same. When the distance between the roof 250 and the body 210 is less than 1 cm, the insect inflow hole is too small to reduce insect collecting efficiency. When the distance is longer than 8 cm, the suction fan 212 The formed airflow may not be formed with sufficient strength, resulting in a problem that the insect trapping efficiency is lowered.

Accordingly, when the insect is attracted by the attracted light, particularly ultraviolet rays, and approaches the catcher 200, the insect air flows into the space between the body 210 and the attracted light source cover part 230 by the suction air flow formed by the suction fan 212 And can be collected by the collecting unit 220 located below the air collecting unit 216 through the insect inflow port 210a and the suction fan 212. [

Thus, the catcher 200 according to an embodiment of the present invention is configured such that the airflow formed by the suction fan 212 is formed between the roof 250 and the body 210 So that the suction fan 212 can effectively generate the suction airflow in a fluid-dynamic manner. As a result, even if the rotational speed of the suction fan 212 is driven in the range of 1800 rpm to 3100 rpm, the suction airflow is formed to be 0.5 m / s to 3 m / s so that the mosquito does not stick to the suction fan 212, 220, respectively.

For example, the attracted light source cover unit 230 may be mounted on the underside of the roof 250. For example, the roof 250 may be composed of a detachable upper member and a lower member, and the upper member may include a hole through which the attracted light source 20 can be inserted, May be provided. Accordingly, the attracted light source 20 is seated on the attracted light source cover unit 230 by inserting the attracted light source 20 into the hole provided in the upper member in the upward and downward direction after separating the upper member from the lower member. .

Although not shown in the drawing, a material capable of reflecting the attracted light emitted by the attracted light source 20 on the lower surface of the roof 250 may be adhered or coated. The material capable of reflecting the attracted light is not particularly limited and may be coated with a material such as silver or aluminum and may be coated on the lower surface of the light source cover part 230 attracted by the silver or aluminum film, Various types of curved or uneven patterns may be added.

In addition, the attracted light source cover unit 230 may include a transparent material to prevent the attracted light source 20 from being damaged due to approach of external dust or insects.

The attracted light source cover part 230 may be formed into various shapes to perform a function of diffusing light emitted from the attracted light source 20 or converging the light in a predetermined direction. The attracted light source cover part 230 may include materials such as glass, quartz, and the like. In addition, since PMMA (poly methyl methacrylate) having a monomer ratio of about 80% or more is composed mainly of carbon and hydrogen, the electron cloud is thin and the UV transmittance is high, so that the attracted light source cover part 230 can be formed have. Further, fluorinated polymer which is a stable material which does not react with ultraviolet rays can be used as the attracted light source cover part 230. For example, it is preferable to make the thickness thinner while having a relatively flexible physical property in consideration of the fact that the ultraviolet transmittance is lower than that of quartz or PMMA. That is, in order to use the fluoropolymer as the attracting light source cover part 230, the ultraviolet transmittance must be considered. In the case of the fluoropolymer, since the ultraviolet transmittance is lower than that of the quartz or PMMA, the thinner the thickness, the higher the ultraviolet transmittance. 230 may be easily broken even by a small impact owing to the brittleness of the polymer, it is preferable that the material itself is made of a flexible soft material to reduce the brittleness.

The manned light source (20)

Since the attracted light source 20 is similar to the attracted light source 10 described with reference to Figs. 1 to 3, detailed description thereof will be omitted in order to avoid duplication.

<2-2. Catcher (200)

Fig. 6 is a perspective view showing a retainer according to a second embodiment of the present invention, and Fig. 7 is a sectional view of Fig. 6. Fig.

The trap unit according to the second embodiment mode comprises an air dust collection unit 216 for blocking the escape of the insects trapped in the trapping unit 220, a lower light source (not shown) disposed between the suction fan 212 and the trapping unit 220 The configuration of the catcher according to the second embodiment is applied except for the constitution further comprising a photocatalytic filter installation part 215a disposed below the lower light source 214 and capable of mounting the photocatalytic filter 215 And a detailed description of the redundant configuration will be omitted.

air Dust collector (216)

7 to 8, the air collecting part 216 is mounted on the lower part of the body 210 and is provided with air sucking parts 216a, And the air collecting portion discharge port 216e may include an air collecting portion side port 216b and an air collecting portion discharging port 216e. The air collecting portion 216 may include a cone shape or a tapered shape, (taper) shape. In addition, the air collecting portion 216 may include a section having a different slope of the cross section.

That is, the air dust collecting part 216 is formed in a tapered shape having a smaller diameter as it moves away from the suction fan 212 in order to effectively send airflow generated by the suction fan 212 to the lower collecting part 220 without dispersing tapered shape. In particular, it may include two or more sections having different slopes of the cross section, and may include three sections having different slopes, for example.

For example, as shown in FIG. 8, the slope of the cross section of the air dust collection section 216 may be a steep section, a gentle section, and a vertical section (air outlet portion) 216e in a downward direction from the top, The slope of the vertical cross section may be in the order of the air outlet portion inclination 216h> the inlet portion inclination 216f of the air intake portion> the middle portion inclination 216g of the air intake portion.

The mosquitoes trapped in the collecting part 220 tend to gather into the space formed between the inlet part 216c of the air collecting part and the collecting part 220 by controlling the inclination of the vertical section of the air collecting part 216, The frequency at which the mosquito escapes from the catcher 200 when the fan 212 is stopped can be remarkably lowered.

Specifically, the inlet portion 216c of the air collecting portion may have an angle formed by the vertical cross section of the ground surface from 45 to 80, and preferably from 60 to 85. When the angle formed by the vertical cross section of the air intake part 216c from the ground surface is less than 45 degrees, the incidence of the mosquitoes escaping from the catcher 200 is excessively increased when the suction fan 212 is stopped, The space formed between the dust collecting part 216 and the inner wall of the collecting part 220 is too narrow and it is difficult to expect that the mosquito collects in the space formed between the air collecting part inlet part 216c and the collecting part 220. [

In addition, when the air collecting part 216 further includes the air collecting part discharging opening 216e extending toward the collecting part 220, that is, the lower part, the mosquito tends to stick to the air collecting part discharging opening 216e, Therefore, when the suction fan 212 stops, the frequency with which the mosquito escapes from the catcher 200 can be remarkably lowered. In this case, the length of the air suction portion discharge port 216e in the vertical direction may be 0.2 cm to 2 cm, preferably 0.5 cm to 1.5 cm, and when the suction fan 212 is larger than 2 cm, When the suction fan 212 is stopped, the area where the mosquito sticks to the air outlet part 216e is too small, so that the effect of suppressing the escape of the mosquito may be insufficient.

8, the air dust collection unit 216 includes a plurality of air dust collection units 216a and air collection units 216a, which are provided to pass the air introduced by the suction fan 212, Mouth 216b.

That is, the air dust collecting part 216 may include the air collecting part side surface 216b so that the airflow generated by the suction fan 212 can effectively escape to the outside of the catcher 200. The shape of the side wall of the air collecting part 216b is not particularly limited and may be a mesh shape or a slit shape. The area of the hole formed by the mesh shape or slit shape can be controlled so that insects, particularly mosquitoes, can not pass through.

When the air collecting part side sills 216b are slit-shaped, each of the air dust collecting parts 216a has a shape in which two rod-shaped parts having a length and a width overlap each other in a part of the width, May be arranged close to a portion disposed below the neighboring air-intake manifold 216a. That is, the air dust collecting part 216 has a shape in which a part disposed above one air dust collecting part 216a and a part disposed below the other air dust collecting part 216a face each other through the side surface of the air dust collecting part 216b And may be formed in a continuous structure. By adopting the above structure, not only the airflow is effectively formed by the suction fan 212, but also the frequency of the mosquitoes collected in the collecting unit 220 escaping out of the catcher 200 when the suction fan 212 is stopped Can be lowered. At this time, since the air dust collecting part 216a and the air collecting part side surface 216b are formed in the vertical direction of the catcher 200, the air resistance is much reduced as compared with the case of being formed in the lateral direction, It is possible to prevent the air flow from being disturbed by the mosquito trapped on the side surface of the air collecting part 216b.

Particularly, it is possible to control the shape of the air dust collector 216a according to the direction of the airflow formed by the suction fan 212. [ Specifically, the airflow formed by the suction fan 212 contacts the portion disposed above the air damper body 216a and then contacts the portion disposed below the air damper body 216a. So that the airflow formed by the suction fan 212 can be effectively exhausted through the side surface of the air collecting part 216b to control the intake air flow hydrodynamically. Therefore, the catcher 200 according to the embodiment of the present invention controls the shape of the air suction portion 212a so that the suction fan 212 can be rotated in a range of 1800 rpm to 3100 rpm The speed of the air flow formed by the intake fan 212 can be controlled to be 0.5 m / s to 3 m / s, so that the insect is not trapped in the suction fan 212 by the physical impact, So that the catcher 200 can be driven.

That is, the catcher 200 according to the embodiment of the present invention controls the slope of the vertical cross section of the air dust collection part 216 to be different, and controls the shape of the air dust collection part discharge port 216e and the shape of the air dust collection part 216a The insect airflow generated by the suction fan 212 can be effectively escaped and the collection efficiency can be improved. After the inflowing insects are collected in the collecting unit 220, the collected insects are collected through the air collecting unit 216, It can be driven so as not to escape to the outside.

The lower light source 214,

7, the catcher 200 may include a lower light source 214 disposed between the suction fan 212 and the collecting unit 220. The lower light source 214 can irradiate light toward the photocatalytic filter 215.

The lower light source 214 may provide light having a wavelength of at least one of an ultraviolet ray, a visible ray, and an infrared ray, and may preferably provide ultraviolet rays.

The wavelength of the light emitted from the lower light source 214 may be 200 nm to 400 nm and may be controlled to be 200 nm to 300 nm when the lower light source 214 is used for sterilization purposes, 214 may have an optical output of 500 mW to 3000 mW when the input voltage is 5 V to 30 V and the input current is 50 mA to 100 mA. The reaction efficiency of the photocatalytic filter 215 can be improved when the light irradiated from the lower light source 214 is within the above wavelength range or exhibits the light output.

The lower light source 214 may include at least one light emitting chip or at least one light emitting diode package mounted on the light emitting substrate.

The lower light source 214 may include a point light emission type, and the point light emission light source may be formed by a distance of 2 mm to 50 mm from another point light emission source.

Further, the lower light source 214 can irradiate the UVC, sterilize the catcher 200, or insect the insect trapped in the catching part 220. [

The shape of the lower light source 214 is not particularly limited and may be located between the collecting part 220 and the suction fan 212, for example, between the photocatalytic filter installing part 215a and the suction fan 212. [

The lower light source 214 may be supported by a single or a plurality of supports extending from the lower end of the body 210 or the air dust collection part 216 or may be supported by the photocatalytic filter installation part 215a Can be installed.

At this time, the lower light source 214 is disposed at the center of the lower end of the body 210 or at the lower portion of the hub of the suction fan 212 so as not to interfere with the path where the insects passing through the suction fan 212 are collected by the collecting part 220 . The lower light source 214 is disposed at a lower portion of the suction fan 212 so that the surface on which heat is generated by the lower light source 214 such as a surface on which the light emitting chip is not mounted corresponds to the suction fan 212 So that the heat generated by the lower light source 214 is cooled by the airflow formed by the suction fan 212, thereby improving reliability or durability of the lower light source 214. [

Photocatalytic filter (215)

7, in the retainer 200, the photocatalytic filter 215 may be mounted on the photocatalytic filter mounting portion 215a.

The photocatalytic filter 215 may comprise a material that provides a photocatalytic reaction as a photocatalytic medium. Specifically, the photocatalytic medium may include at least one selected from the group consisting of titanium oxide (TiO2), silicon oxide (SiO2), tungsten oxide (WO3), zirconium oxide (ZnO), strontium titanium oxide (SrTiO3), niobium oxide (Nb2O5) A photocatalytic medium formed from any one selected from the group consisting of zinc oxide (ZnO2), and tin oxide (SnO2), or a combination thereof. For example, the photocatalytic filter 215 may be formed in a layered structure including titanium oxide (TiO2).

The photocatalytic filter 215 may be made of a material such as a metal foam or a porous ceramic that is coated with a material through which an air flow can flow, or may have a structure capable of air flow.

The photocatalytic filter 215 can perform a photocatalytic reaction with ultraviolet rays of about 200 nm to 400 nm emitted from the lower light source 214. When ultraviolet rays are absorbed in the photocatalytic medium, electrons (e) and holes (+) are generated on the surface and move to the surface of the photocatalyst. The generated electrons and holes cause redox reaction with contaminants in the air, Can be removed. Further, electrons generated on the surface of the photocatalyst react with oxygen present on the surface of the photocatalyst medium to generate a superoxide anion radical (O2-), and holes form hydroxyl groups (-OH) present on the surface of the photocatalyst or air, Or may react with water to produce a hydroxyl radical (--OH-).

The hydroxyl radicals generated in the reaction can act as a strong oxidizing agent to perform a sterilizing action and oxidize and decompose organic pollutants in air to decompose contaminants and odor substances in the air introduced into the trap 200, Carbon dioxide.

That is, the trapper 200 can perform the sterilization and deodorization function while the photocatalytic reaction is proceeding in the photocatalytic filter 215 by the ultraviolet light irradiated by the lower light source 214.

The carbon dioxide formed by the photocatalytic reaction is known as a substance having a high mosquito inducing effect. In order to increase the generation efficiency of the carbon dioxide, an attractant such as lactic acid, amino acid, sodium chloride, uric acid, ammonia, Filter 215 as shown in FIG. The method of providing the attractant is not particularly limited. For example, the attractant may be applied to the photocatalyst layer 215 in the photocatalyst filter 215, or may be injected into the photocatalyst layer periodically or aperiodically. The increased carbon dioxide concentration can further increase the attractiveness of insects.

That is, the trap 200 according to an embodiment of the present invention can be expected to have a sterilizing and deodorizing effect by providing the lower light source 214 and the photocatalytic filter 215, Especially, the effect of attracting mosquitoes can be expected.

The light source cover part 330 may be formed such that the surface of the light source cover part 330 is irregularly processed or a separate cover plate may be attached to or spaced from the front or rear of the light source cover part 330. Meanwhile, The light source cover part 330 may be arranged to be rotatable in the body 310 and the user may change the arrangement of the attracted light source cover part 330 according to the use environment.

For example, a portion through which the light emitted from the light source 30 is transmitted may be a polycarbonate (PC) (PET), methacrylate-styrene (MS), polymethylmethacrylate (PMMA), and the like, and may include at least one of transparent, semitransparent, and colored materials such as polyethylene terephthalate May be formed with a color containing

The manned light source (30)

The attracting light source 30 can be applied to the constitution and use embodiments of the attracting light source 10 described above.

The attracted light source 30 may also be a tube-type LED. The tube-type LED may be electrically connected to an external power supply device by wire bonding or without wire bonding. For example, the tube-type LED is provided with a light emitting diode 12 attached to a support member 31, a heat sink 32 on which a support member 31 is mounted, and a support member 31 and a heat- And a base 34 coupled to both ends of the case 33 housing the sink 32.

At least one surface of the support member fixing portion 35 may include a support member 31, And the height increases from the inner side toward the outer side. For example, the tube-type LED may have a light-emitting chip 12 attached to both sides of the support member 31, one surface of which is attached with a pest-inducing light-emitting diode, and the other surface of which is a sterilizing and insecticidal UVC light- .

As described above, the present invention provides a trapper capable of maintaining a high efficiency of insect pest attraction and enhancing user's convenience in use, while maintaining high attraction efficiency of insect pest using ultraviolet rays and blocking external emission of visible rays The present invention will be described in detail below.

&Lt; Optical filter according to the first embodiment &

The optical filter according to the first embodiment includes a band stop filter (band stop filter), which will be described with reference to FIGS. 11 and 12. FIG.

11 and 12 illustrate a man-made light source having a band-stop filter according to an embodiment of the present invention. The man-made light source includes manned light sources 10, 20, and 20 mounted on the catchers 100, 200, 30, and the configurations described above can be applied to all of the configurations not described below.

11 and 12, the manned light source includes a substrate 11, a light emitting chip 12 provided on the substrate 11, and a band stop filter (band stop filter) 13a.

Although the band-stop filters 13a and 13b have been described in the present specification, various other filters may be used to selectively or non-emit light of a specific wavelength band. For example, in addition to a band-stop filter that blocks only a predetermined wavelength band, a low-pass filter that passes only a low frequency band, a high-pass filter that passes only a high frequency band, a bandpass filter that passes only a predetermined band Band Pass Filter) can be borrowed.

The substrate 11 is a support member for supporting the light emitting chip 12, and may include a printed circuit board having wiring, for example. For example, the substrate 11 may be a printed circuit board having a circuit pattern in an area where the light emitting chip 12 is to be mounted, and the substrate 11 may be made of a metal, a semiconductor, a ceramic, .

The light emitting chip 12 may be provided on the substrate 11, and a plurality of the light emitting chips 12 may be provided. The light emitting chips 12 may be provided on both sides with the substrate 11 therebetween. The light emitting chip 12 may include a UV-LED chip that emits ultraviolet light.

The band-stop filters 13a and 13b may be provided on the light-emitting chip 12 in such a manner as to cover at least a part of a portion where light is emitted from the light-emitting chip 12. [ The band-stop filters 13a and 13b block the predetermined wavelength band as described above, and may include, for example, a distributed Bragg reflector.

The distributed Bragg reflector may be formed by alternately repeating layers of two or more layers having different refractive indices. For example, the light emitting chip 12 may have a reflectance of 80% or more with respect to light of a visible light wavelength range of 390 nm or more and a reflectance of 20% or less with respect to light of an ultraviolet wavelength range. As another example, the distributed Bragg reflector may have a reflectance of 80% or more with respect to the light of 390 nm to 500 nm wavelength generated in the light emitting chip 12, and a refractive index of 20% or less with respect to light in the ultraviolet wavelength range Different layers can be repeatedly laminated. On the other hand, the reflectance may differ depending on the constituent components of the distributed Bragg reflector and the number of stacked layers.

On the other hand, the layers to be laminated do not need to have the same thickness, but may have a relatively high reflectivity for light of a specific wavelength that is not emitted to the outside of the attracted light source, and a relatively low reflectance for light of ultraviolet wavelength Can be selected.

The distributed Bragg reflector may be formed, for example, by alternately laminating a SiO2 layer and a TiO2 layer, or an SiO2 layer and an Nb2O5 layer. Also, the first and last layers of the distributed Bragg reflector may be SiO ₂ , but are not limited thereto. For example, a dielectric layer having a lower refractive index than SiO2, for example a MgF2 layer, may be used as the first layer.

The band-stop filters 13a and 13b may be disposed on the side from which light is emitted from the light-emitting chip 12. [ As shown in Fig. 11, the band-stop filter 13a may be disposed on the upper surface of the light-emitting chip 12. However, the present invention is not limited thereto, and may be arranged to cover not only the upper surface but also the side surface of the light emitting chip 12, as shown in Fig. Thus, the effect of blocking the external emission of visible light, particularly blue light, generated in the light emitting chip 12 can be further improved.

&Lt; Optical filter according to the second embodiment &

The optical filter according to the second embodiment includes a molding part including a light filter material, and will be described with reference to FIG.

13 shows an attracted light source having a molding part according to an embodiment of the present invention.

Referring to FIG. 13, the attracting light source may include a substrate 11, a light emitting chip 12, and a molding portion 14.

The substrate 11 and the light emitting chip 12 can be applied as described above with reference to Figs. 11 and 12, and the molding portion 14 can cover at least a part of the light emitting portion of the light emitting chip 12 .

At this time, the molding part 14 may include the transparent member 14 and the light filter material 1. [ The light filter material 1 blocks the light of at least a part of the visible light emitted from the light emitting chip 12 from being emitted to the outside. For example, the light filter material 1 has a visible light ray of 390 nm or more, It can have a light absorptivity of 80% or more with respect to the light in the wavelength region and a light absorptivity of 20% or less with respect to light in the ultraviolet wavelength region. The type and amount of the light filter material 1 can be appropriately controlled. As another example, the optical filter material 1 may have a light absorptivity of 80% or more with respect to the light of 390 nm to 500 nm wavelength generated by the light emitting chip 12, and a light absorptance of 20% or less with respect to the light of the ultraviolet wavelength region Respectively.

For example, the light filter material 1 may comprise a wavelength converting material.

For example, the wavelength converting material may absorb blue light in the range of 400 to 500 nm and emit light having a wavelength longer than blue light, for example, light having a wavelength of 500 nm or more. Thus, the excitation spectrum of the wavelength converting material may have a maximum value within the range of 400 to 500 nm, and the emission spectrum may have a maximum value at 500 nm or more. The wavelength converting material may be excited by blue light to emit green or red light. Alternatively, the wavelength converting material may also be excited by blue light to mainly emit light in the infrared region.

For example, the wavelength converting material may emit blue light in a wavelength range of visible light, for example, in the range of 400 to 500 nm to emit light having a shorter wavelength than blue light, for example, ultraviolet light having a wavelength of 400 nm or less. Therefore, the inconvenience that the user feels by the visible light can be removed, and the efficiency of the light introduction of the insect can be further improved.

Since the night vision sensitivity is high at the blue wavelength, it is possible to reduce the sensitivity of light that can be felt at night by converting blue light into green or red light by wavelength conversion, and also to reduce blue light and prevent eye fatigue by light.

On the other hand, the wavelength conversion material may have a water absorption rate of 20% or less with respect to the ultraviolet light emitted from the light emitting chip 12, thereby enhancing the convenience of the user without significantly reducing the pest inducing performance of the attracting light source.

&Lt; Optical filter according to the third embodiment &

The optical filter according to the third embodiment is disposed apart from the light emitting chip 12. For example, the optical filter includes a form coated or coated on at least a part of the attracted light source cover portion, and will be described with reference to Figs. 14 to 16 below.

14 shows a retainer 100a provided with an optical filter 15 in the retainer 100, Fig. 15 shows a retainer 200a provided with an optical filter 25 in the retainer 200, Fig. The configuration of the retainers 100, 200, and 300 described above is applicable to the configuration excluding the optical filters 15, 25, and 35, respectively.

The retainers 100a, 200a and 300a may include optical filters 15, 25 and 35 at least in a part through which light emitted from the manned light sources 10, 20 and 30 passes. The light filters 15, 25 and 35 may comprise a band-stop filter or light filter material 1 which blocks light emission of at least some of the visible light emitted from the light-emitting chip 12, The band-pass filter according to the first embodiment and the optical filter material 1 can be applied to the optical filter according to the second embodiment.

For example, referring to FIGS. 14 to 16, the optical filters 15, 25, and 35 may be provided in the manned light source cover units 130, 230 and 330. At this time, the attracted light source cover parts 130, 230 and 330 are made of a transparent or translucent material capable of transmitting light, and include an optical filter 15 in the form of a band stop filter or a coated or coated optical filter material 1 can do.

For example, the optical filters 15, 25, and 35 may be provided in at least a part of the area where the attracted light is emitted from the attracted light source cover parts 130, 230, and 330. For example, The light source cover units 130, 230, and 330 may be provided on both front and rear surfaces of the light source cover units 130, 230 and 330, , 25, 35) may be applied or coated.

For example, the optical filters 15, 25 and 35 can be manufactured in the form of a film, and the optical filters 15, 25 and 35 in the form of a film can be detachably attached to the attracted light source cover parts 130, Lt; / RTI &gt;
