Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 are views showing a catcher 1 according to an embodiment of the present application. 1 and 2 illustrate in greater detail the form of the insect passage 21 of the retainer 1 of Fig. 1, respectively; Fig. 1 is a perspective view showing the retainer 1 according to an embodiment of the present application; It is a perspective view showing.

1, the retainer 1 includes an upper cover portion 10, a body portion 20, and a lower support portion 30. As shown in FIG.

The upper cover portion 10 has a shape corresponding to the upper surface of the body portion 20. For example, as shown in FIG. 1, the cross-sectional area of the upper cover portion 10 in the first direction and the second direction may have a shape corresponding to the body portion 20.

The upper cover portion 10 is installed to open and close the upper surface of the body portion 20. For example, when the retainer 1 is not operated, the support bars formed at both ends of the upper cover part 10 are inserted in the direction of the body part 20, so that the upper cover part 10 is inserted into the body part 20 The upper surface can be shielded. As another example, when the retainer 1 is operated, the support rods formed at both ends of the upper cover portion 10 slide in the direction opposite to the body portion 20, so that the upper surface of the body portion 20 can be exposed to the outside have.

A light source is provided on a lower surface of the upper cover portion 10. The light source irradiates ultraviolet rays in a horizontal direction to attract insects to the spaced space between the upper cover portion 10 and the body portion 20. [

For example, the light source provided on the upper cover portion 10 may be a UV LED, and may be irradiated with ultraviolet rays having a peak wavelength between 340 nm and 400 nm. However, this is an example, and if there is an attracting effect on an insect, the UV LED may irradiate ultraviolet rays having wavelengths other than 340 nm to 400 nm.

The body portion 20 is formed to have an open top and bottom so that outside air can flow into the body portion 20 and air inside the body portion 20 can be discharged to the outside. For example, the body portion 20 may be formed in a cylindrical shape as shown in FIG. 1, but the present invention is not limited thereto.

Inside the body 20, a fan and a motor for driving the fan are installed. For example, when the retainer 1 is operated, the fan flows air between the upper cover portion 10 and the insect passage portion 21 and the surrounding air. The fluidized air is sucked into the body portion 20 through the insect passage portion 21 formed on the upper surface of the body portion 21 together with the insect and discharged to the lower portion of the body portion 20 again.

At the lower end of the body portion 20, a collecting case for collecting insects discharged downward from the body portion 20, though not shown, may be provided. The collection box can be formed in the form of a net or a basket, and can be detachably attached.

The lower support portion 30 is provided at the lower end of the body portion 20 and functions to support the catcher 1 from the ground. The lower support 30 includes at least one support, which can be slidably inserted into the body 20.

2 and 3, the insect passage portion 21 includes a blocking portion A, a plurality of insect through holes 21_1, and first to third motor supports 21_21 to 21_23.

The shielding portion A is formed at the center of the insect passage portion 21 and functions to shield the motor provided at the lower portion from being exposed to the outside. For example, the covering portion A may be formed in a circular shape corresponding to the motor, and may be formed to have the same area as the horizontal cross-sectional area of the motor.

The plurality of insect passage holes 21_1 are formed in the peripheral region of the covering portion A with the covering portion A as a center. The plurality of insect through holes 21_1 are separated by the covering portion A and the ribs, respectively, and serve as a filter for selectively passing insects.

The first to third motor support portions 21_21 to 21_23 are formed on the lower surface of the insect passage portion 21 and serve to receive and fix the motor for driving the fan and / or the fan. For example, a motor may be disposed in a space formed between the first to third motor support portions 21_21 to 21_23 and the shielding portion A, and the first to third motor support portions 21_21 to 21_23 may be a motor So as to fix the motor when the motor is driven.

2 and 3, the first to third motor support portions 21_21 to 21_23 are formed on the lower surface of the rib, respectively. When the motor is driven, each of the first to third motor support portions 21_21 to 21_23 absorbs the shock due to the motor driving. When the motor support portion is formed on the lower surface of the rib, the first to third motor support portions 21 ~ 21 ~ 21 ~ 23) are transmitted to the ribs. Therefore, there is a risk that the rib having a weak strength at the time of driving the motor is broken.

Hereinafter, the catcher and the insect passage portion according to another embodiment of the present application, which can further reduce the risk of rib breakage described above and further improve the insect collecting efficiency, will be described in more detail.

FIGS. 4 to 6 are views showing a retainer 1000 according to an embodiment of the present application. 4 and 5 are perspective views showing a retainer 1000 according to an embodiment of the present application, and FIG. 6 is a perspective view illustrating a state of the overall engagement of the retainer 1000 according to an embodiment of the present application Fig.

The catcher 1000 shown in Figs. 4 to 6 is implemented with a wider area of the inserting portion of the insect passage than the catcher 1 shown in Figs. 1 to 3. Accordingly, the plurality of motor supporting portions 235_1 to 235_3 are formed on the lower surface of the covering portion B, not on the ribs, so that the possibility of breakage due to the motor vibration during the catching operation can be lowered.

4 to 6, the retainer 1000 includes an upper cover portion 100, a body portion 200, and a lower support portion 300.

The upper cover part 100 functions to open and close the opening formed on the upper surface of the body part 20. [ The upper cover part 100 includes an upper cover 110, a lower cover 120, an upper support part 130, and a light source mounting part 140.

The upper cover 110 forms an outer appearance of the retainer 1000 and has a shape capable of shielding the opening formed on the upper surface of the body portion 200.

For example, the upper cover 110 may be formed to have a cross-sectional area in a horizontal direction similar to an opening formed in the upper surface of the body 200. 4, when the upper cover part 100 is separated from the body part 200, the upper cover part 100 can be easily grasped, Protrusions protruding in the first direction may be formed on both sides. However, the upper cover 100 may be formed in various shapes without limitation as long as the upper cover 100 can shield the opening formed on the upper surface of the body 200.

The lower cover 120 is coupled with the upper cover 110 and provides a space in which the upper support 130 and the light source mount 140 can be installed. 5, the lower cover 120 has a shape corresponding to the upper cover 110, and is fitted to the step formed on the outer circumferential surface of the upper cover 110, so that the upper cover 110 Can be combined. However, the lower cover 120 may be formed in various shapes and may be coupled to the upper cover 110 in a manner such as a screw connection.

The upper support 130 is formed on the lower surface of the lower cover 120. For example, the upper support 130 may be injection molded with the lower cover 120, in which case the upper support 130 may be provided as an integral part of the lower cover 120. The upper cover 130 may be formed separately from the lower cover 120, and may be fixed to the lower cover 120 by screwing or fitting.

The upper support 130 functions to support the upper cover 100. For example, when the retainer 1000 operates, the upper support 130 supports the upper cover part 100 such that a constant space is formed between the body part 200 and the upper cover part 100. The upper support 130 slides in the direction of the body 200 in a state where the upper support 130 is inserted into the upper guide of the insect passage 230, As shown in FIG. The specific configuration and combination of the upper support 130 and the body 200 will be described in more detail with reference to FIG. 9 below.

The light source mounting portion 140 is formed on the lower surface of the lower cover 120. The light source mounting portion 140 is provided with a light source for attracting insects. The light source irradiates ultraviolet rays in a horizontal direction to attract insects to a space spaced between the upper cover portion 100 and the body portion 200.

For example, the light source may be a UV LED, and may be irradiated with ultraviolet light having a peak wavelength between 340 nm and 400 nm. However, this is an example, and if there is an attracting effect on an insect, the UV LED may irradiate ultraviolet rays having wavelengths other than 340 nm to 400 nm.

As another example, a plurality of UV LEDs may be used as the light source. In this case, each of the plurality of UV LEDs can emit ultraviolet rays of a wavelength range having an attracting effect on insects. For example, a plurality of UV LEDs can irradiate ultraviolet rays of the same wavelength band, each of which has an insect attracting effect. However, this is an example, and if there is an attracting effect on an insect even if ultraviolet rays of different wavelengths, a plurality of UV LEDs may irradiate ultraviolet rays of different wavelengths.

As another example, a plurality of UV LEDs can be used as a light source, and only a part of a plurality of UV LEDs can irradiate an ultraviolet ray of a wavelength band having an attracting effect on an insect. For example, at least one of the plurality of UV LEDs may irradiate an ultraviolet ray of a wavelength band having an attracting effect to an insect, and the other UV LED may irradiate an ultraviolet ray of a sterilizing wavelength band. However, this is only an illustrative example. In addition to the UV LED of the sterilizing wavelength band, UV LEDs of various wavelengths may be used as a light source together with a UV LED having an attracting effect to an insect. The structure of the light source installed in the light source mounting part 140 and the light source mounting part 140 will be described in more detail in FIG. 17 and FIG. 18 below.

The body part 200 is configured to introduce outside air and insects into the inside of the body part 20 and to discharge air and insects inside the body part 20 downward. The body portion 200 may include an outer housing 210, an inner housing 220, an insect passage portion 230, and a fan guard portion 240. Inside the body portion 200, 10) and a motor 410 for driving the fan 420 are mounted.

The outer housing 210 forms the outer surface of the retainer 1000, i.e., the side wall of the retainer 1000. The outer housing 210 can be formed, for example, in a cylindrical shape with its top and bottom opened. However, this is an example, and the outer housing 210 may be formed in various shapes.

The inner housing 220 is coupled to the outer housing 210 and a predetermined inner spacing space may be formed between the outer circumferential surface of the inner housing 220 and the inner circumferential surface of the outer housing 210. For example, at least one of the upper support 130 and the lower supports 310-340 may be received in such an interior spacing space. As another example, at least one of the upper support 130 and the lower supports 310-340 may be housed in a structure such as a guide formed in an inner spacing space. Meanwhile, the structure of the inner housing 220 is exemplary, and the inner housing 220 may be formed in various shapes and structures. For example, the outer circumferential surface of the inner housing 220 is in close contact with the inner circumferential surface of the outer housing 210, and may be formed to reinforce the strength of the outer housing 210.

The inner housing 220 provides a space for installing the fan 420 and the motor 410 for driving the fan. The internal housing 220 is connected to an external power source and includes a power supply for supplying power to the motor 410 and the light source, a voltage charging unit for charging a voltage supplied from the outside, And a control unit for controlling the power provided to the light source.

The insect passage portion 230 includes a blocking portion B and a plurality of insect passage holes 231. The covering portion B is formed at the center of the insect passage portion 230 and covers the motor 410 installed at the lower portion so as not to be exposed to the outside.

In the embodiment according to the technical idea of the present application, the area of the closure part B of the insect passage part 230 is realized to be larger than the area of the closure part A of Figs. Therefore, unlike the retainer 1 of FIGS. 1 to 3, the plurality of motor supports 235_1 to 235_3 may be formed on the lower surface of the cover B, not on the ribs. Compared with the catcher 1 of Figs. 1 to 3 in which the motor support portions 21_21 to 21_23 are formed on the lower surface of the rib, the catcher 1000 of Figs. 4 to 6 has a reduced possibility of rib breakage due to motor vibration . The structure of the insect passage portion 230 according to the technical idea of the present application will be described in more detail with reference to Figs. 7 to 10 below.

The fan guard portion 240 is formed on the lower surface of the body portion 220 and serves to prevent a foreign object having a large size from entering the inside of the body portion 200.

For example, if foreign objects other than insects are pulled in from the opening formed in the lower surface of the body portion 200 when the retainer 1000 is operated, the motor 410 and / or the fan 210 may fail. The fan guard portion 240 may be formed on the lower surface of the body portion 220 to prevent the entry of such unwanted foreign matter.

As shown in FIG. 5, the fan guard portion 240 may be formed in a radial shape with respect to a center circle of the center. However, the fan guard portion 240 may be formed in various shapes without any limitations as long as it has a structure for preventing foreign matter from being introduced, such as a grate shape, a mesh shape, or the like.

Concave and convex portions may be formed in a part of the edge of the fan guard portion 240. [ Such concavity and convexity acts to generate a frictional force between the collecting box and the collecting box, and to engage the collecting box with the concavity and convexity, thereby fixing the collecting box to the fan guard portion 240. An example in which the collecting case is mounted on the fan guard portion 240 will be described in more detail in FIGS. 20 and 21 below.

The fan guard part 240 may be injection molded together with the inner housing 220 and the fan guard part 240 and the inner housing 220 may be provided as an integral part. However, this is merely an example, and the fan guard portion 240 may be fixedly coupled to the inner housing 220 by screws or the like.

The lower support part 300 is installed at the lower end of the body part 200 and functions to support the catcher 1000 from the ground.

The lower support 300 includes at least one lower support. For example, as shown in FIGS. 4 to 6, the lower support 300 may include four lower supports 310 to 340, but is not limited thereto.

For example, the lower support 300 may include two lower supports, in which case the cross-sectional areas of the lower supports in the first and second directions are the same as those of the lower supports 310-340 of FIGS. 4-6. As shown in FIG. In this case, the diameter of the lower support part 300 may be smaller than the diameter of the outer housing part 210. In this case, the diameter of the lower support part 300 may be smaller than the diameter of the outer housing part 210 So that the upper part of the lower supporting part 300 can be drawn into the body part 200.

The lower support part 300 may be slidably inserted into the body part 200,

For example, first to fourth guide guides (not shown) corresponding to the first to fourth lower supports 310 to 340 may be installed between the outer housing 210 and the inner housing 220 . In addition, the first to fourth lower supports 310 to 340 may each have a coupling groove, and the first to fourth guide guides may have elastic members, such as ball plunge, .

Accordingly, the user can insert the first to fourth lower supports 310 to 340 into corresponding first to fourth guide guides, respectively, and the first to fourth lower supports 310 to 340 The first to fourth lower supports 310 to 340 can be fixedly inserted into the body 200 by the fastening members formed in the fastening groove and the first to fourth guide guides. The user can insert the lower support part 300 into the body part 200 when the retainer 1000 is not used and in this case the entire volume of the retainer 1000 is reduced and the portability can be improved.

FIGS. 7 to 10 are views for explaining the insect passage portion 230 of the catcher 1000 of FIGS. 4 to 6 in more detail. 7 and 8 are perspective views showing the insect passage portion 230 of the retainer 1000 in more detail and FIG. 9 is a perspective view of the insect passage portion 230 of the retainer 1000, FIG. 5 is an exploded perspective view showing the state of the coupling of FIG. 10 is an exploded perspective view for showing a state in which the insect passage portion 230 of the retainer 1000, the motor 410 and the fan 420 are engaged.

7 and 8, the insect passing portion 230 includes a covering portion B and a plurality of insect passing holes 231, and a slope of a predetermined angle is formed at the edge of the insect passing portion 230 The flow path guide 236 is formed.

The flow path guide 236 serves to guide air and / or insects into the insect passage hole 231 naturally without pressure loss when the insects flow into the body part 200 through the insect passage part 230. For this purpose, the flow path guide 236 may be formed to have a predetermined inclination angle.

In addition, the flow path guide 236 may be formed to have various depths in the vertical direction. For example, if the vertical depth of the flow guide 236 is shorter than the vertical length of the light source mounting portion 140 (see FIG. 5), when the upper cover portion 100 shields the body portion 200 The light source mounting portion 140 (see Fig. 5) may contact the blocking portion B and break. Therefore, in order to prevent such breakage, the depth of the flow guide 236 in the vertical direction may be longer than the vertical length of the light source mounting portion 140. The vertical depth of the flow guide 236 may vary depending on the length of the light source mounting part 140 in the vertical direction, the shape of the light source mounting part 140, and the mounting form of the light source mounting part 140. [ .

An upper guide 233 is formed on both sides of the flow guide 236 and a guide hole 233_1 is formed through the upper guide 233 and the corresponding flow guide 236 in the vertical direction .

An upper support 130 of the upper cover part 100 is inserted into the upper guide 233. 9, when the retainer 1000 is operated, the upper support 130 is inserted in the upper guide 233 of the insect passage 230 in the opposite direction of the body 200 So that the upper surface of the body 200 is exposed to the outside.

The fixing protrusion 131 of the upper support 130 is elastically coupled to the fixing hole 233_2 formed in the upper guide 233 of the insect passage 230 and the upper cover 100 is coupled to the body 200 As shown in Fig. Through this spacing space, external air and insects can enter the trapper 1000.

The covering portion B is formed at the center of the insect passage portion 230 and covers the motor 410 installed at the lower portion so as not to be exposed to the outside. For example, as shown in FIG. 10, first to third motor support portions 235_1 to 235_3 are formed on the lower surface of the cover portion B, and first to third motor support portions 235_1 to 235_3 are formed. A motor 410 is housed in a space between the motor and the motor.

In the embodiment according to the technical idea of the present application, the area of the closure part B of the insect passage part 230 is realized to be larger than the area of the closure part A of Figs. In this case, the first to third motor supporting portions 235_1 to 235_3 are formed on the lower surface of the blocking portion B, not the ribs. Therefore, the motor vibrations transmitted to the first to third motor support portions 235_1 to 235_3 at the time of the catcher operation are dispersed in the entire area of the covering portion B. As a result, the possibility of rib breakage due to motor vibration during the catcher operation is lowered compared with the catcher of Figs. 1 to 3 where the motor supports are formed on the lower surface of the rib.

On the other hand, as the area of the closure part B of the insect passage part 230 increases, the number of the insect passage holes 230 formed in the insect passage part 230 becomes smaller than that in Figs. For example, in the insect passage portion 21 of Figs. 1 to 3, two rows of insect passage holes are formed centering on the central blocking portion A, whereas the insect passage portion 230 is formed in the center of the cover portion B), only one row of insect passage holes is formed. This decrease in the number of insect passage holes means that the total area opened in the horizontal direction is reduced. As the total open area decreases, the wind speed in each insect passage hole increases, and thus the collecting ability for insects can be improved.

To be more specific, it is assumed that the insulator passing portion 230 of Figs. 7 to 10 and the insulator passing portion 21 of Figs. 1 to 3 have the same outer diameter. It is assumed that motors and fans having the same performance are installed below the insect passing portion 230 and the insect passing portion 21, respectively. Also, assume that the size of each insect passage hole is the same.

In this case, the total area of the insect passage holes 231 formed in the insect passage portion 230 is smaller than the total area of the insect passage holes 23_1 formed in the insect passage portion 21. Therefore, the wind velocity of the air passing through each insect passage hole 231 becomes faster than the wind velocity of the air passing through each insect passage hole 23_1. Therefore, the collecting ability for the insects attracted to each insect passage hole 23_1 can be improved.

It should be understood, however, that the above description is exemplary and that the technical idea of the present application is not limited thereto. For example, the shape and structure of the insect passage according to the embodiment of the present application may be modified in various ways other than the embodiment described above. In the following Figures 11-14, insect passages according to another embodiment of the present application will be illustratively described.

11 to 14 are views showing an insect passage according to an embodiment of the present application. 11 to 14 show insect passage portions in the horizontal direction, that is, in the first and second directions.

11, each insect passage hole 231 of the insect passage portion 230_1 may be formed to have various sizes depending on the performance of the light source and the motor, the position where the insulator is installed, and the like. That is, assuming that the diameter of the inscribed circle of the insect passage hole 231 is " R ", " R " can be variously set according to conditions such as the performance of the light source and the motor.

For example, when the performance of the motor provided below the insect passage portion 230_1 is good, the insect passage hole 231 can be formed such that its inscribed circle has a relatively large diameter R. [ As another example, the insect passage hole 231 may be formed so that its inscribed circle has a relatively small diameter R, in order to prevent an object larger than a predetermined size from being drawn into the catcher 1000 unnecessarily. In this case, for example, the inscribed circle diameter of the insect passage hole 231 may be formed to have a diameter of 7 pi millimeter or more and 10 pi millimeter or less.

Referring to FIG. 12, each insect passage hole 231_1 of the insect passage portion 230_2 can be formed in various shapes. For example, as shown in Fig. 12, the insect passage holes 231_1 can also be formed in the shape of a triangle. It is to be understood, however, that this is only an illustrative example and that the shape of the insect passage hole 231_1 is not limited to a specific shape unless it is difficult to collect the insect.

Referring to FIG. 13, each insect passage hole 231_2 of the insect passage portion 230_3 may be further provided with a projection b. The projection (b) serves to prevent insects or foreign matter having a size large enough to cause a failure of a motor installed below the insect passage portion 230_3, for example, to be prevented from flowing into the trapper .

Referring to Fig. 14, each insect passage hole of the insect passage portion 230_4 can be arranged at various positions. For example, in Figs. 1 to 13, each insect passage hole in the insect passage portion is shown to be regularly formed with respect to the center of the insect passage portion. However, this is an exemplary one, and the technical idea of the present application is not limited thereto. For example, as shown in Fig. 14, the insect passage holes 231_4 may be arranged in an irregular form.

15 and 16 are views for explaining the ratio of the area of the covering portion B to the opening portion having the covering efficiency at the air inlet according to the embodiment of the present application.

For convenience of explanation, an arbitrary point in the air inlet (c) where the outside air flows into the inside is indicated by " e ". It is also assumed that the opening portion refers to a portion that is opened when the blocking portion B is not formed in the insect passage portion 230_5. For example, as shown in Fig. 16, the opening has a circular shape and is assumed to have a diameter of " r1 ". Further, the covering portion B is formed in a circular shape at the center of the insect passage portion 230_5, and is assumed to have a diameter of "r2".

In order to collect insects attracted to the vicinity of the air inlet (e) by ultraviolet rays, the air velocity at the air inlet (e) should be not less than a predetermined speed. For example, when the wind speed at the air inlet (e) is 0.8 m / s or more, insects attracted to the vicinity of the air inlet (e) can be collected in the catcher interior (1000).

The experiment was carried out under the following conditions. First, the outer diameter r1 of the opening portion was 82 pi millimeters (mm), and the area of the opening portion at this time was set to be 5281.17 mm2. The outer diameter r2 of the shielding portion B is 58π mm and the area of the shielding portion B is 2642.08mm2. The distance d between the upper cover part 100 and the body part 200 is set to 3.25 cm. Thereafter, the air velocity at the air inlet (e) was measured while changing the separation distance (d).

Separation distance Wind velocity 3.25 cm (reference distance) 0.85 m / s 4.25 cm 0.67 m / s 5.25 cm 0.5 m / s 6.25 cm 0.46 m / s 1.25 cm 1.1 m / s

As a result of the experiment, it was confirmed that the air inlet (e) had sufficient air velocity to collect insects when the separation distance was 3.25 cm. In other words, it was confirmed that when the ratio of the covering area (2642.08 mm 2) to the opening area (5281.17 mm 2) was about 50% or more, the air inlet e had a wind speed effective for trapping insects. It was confirmed that the wind speed at the air inlet (e) could be slower than 0.8 m / s when the separation distance was longer than 3.25 cm. In other words, it was confirmed that the air inlet (e) had a wind speed effective for collecting insects if the ratio of the opening distance (82 π mm) to the separation distance (3.25 cm) was 13% or less.

As described above, in the retainer 1000 according to the embodiment of the present application, the area ratio of the covering portion B with respect to the opening portion may be 50% or more. In this case, the outer diameter r1 of the opening portion d) is 13% or less, so that insects can be effectively trapped.

17 to 19 are views showing in more detail the installation and structure of the light source 144 according to an embodiment of the present application. 17 is an exploded perspective view of the upper cover part 100 where the light source 144 is installed, and FIGS. 18 and 19 are sectional views showing the structure of the light source 144, respectively.

Hereinafter, referring to Figs. 17 to 19, the light source 144 installed in the retainer 1000 of the present application will be described in more detail.

17, the upper cover part 100 includes an upper cover 110 and a lower cover 120, and the light source attachment part 140 is disposed on the upper surface of the lower cover 120. [

The light source mounting portion 140 may be formed to be open in a direction in which the upper cover 110 is disposed and may include an insertion groove for inserting the PCB 143 and the transparent members 142_1 and 142_2, (Not shown).

At least one of the PCB 143 and the transparent members 142_1 and 142_2 may be inserted and fixed in the insertion groove 141. For example, when the PCB 143 and the transparent members 142_1 and 142_2 are inserted into the insertion groove 141, May be inserted into the light source mounting portion 140 and mounted on the light source mounting portion 140.

At least one light source 144 may be mounted on the PCB 143. The PCB 143 may be formed of a single member or a laminated member in which a single member is laminated. In the case of a PCB formed of a laminated member, the plurality of light sources 144 are arranged in zigzag form in both directions of the stacked type PCB, so that damage to the PCB 143 due to heat generation can be suppressed.

The light source 144 is mounted on the PCB 143 and emits ultraviolet rays toward the outside. For example, the light source 144 may be a UV LED, and may emit ultraviolet light having a peak wavelength between 340 nm and 400 nm. However, this is an example, and if there is an attracting effect on an insect, the UV LED may irradiate ultraviolet rays having wavelengths other than 340 nm to 400 nm.

Further, as shown in FIG. 17, a plurality of UV LEDs may be used as the light source 144. In this case, each of the plurality of UV LEDs can emit ultraviolet rays of the same wavelength. For example, a plurality of UV LEDs may each irradiate ultraviolet light of the same wavelength having an attracting effect on an insect.

As another example, a plurality of UV LEDs that emit ultraviolet rays of different wavelengths to the light source 144 may be used. For example, some of the plurality of UV LEDs may irradiate ultraviolet rays having a attracting effect on insects, and the other UV LEDs may irradiate ultraviolet rays other than the wavelength band having attracting effect on insects such as sterilizing wavelengths There is also. However, this is an illustrative example, and a plurality of UV LEDs may irradiate an ultraviolet ray, which is an insect induction of different wavelengths, respectively, if they have an attracting effect to an insect even though they are ultraviolet rays of different wavelengths.

On the other hand, in Fig. 17, a plurality of UV LEDs are shown as being used as the light source 144. Fig. However, this is merely an example, and one UV LED may be used as the light source 144.

Meanwhile, the retainer 1000 may further include a photocatalyst material. For example, the lower surface of the lower cover 120 may be coated with a photocatalyst material on the inner surface of the upper support 130, the inner surface of the body 200, and the fan 420.

The photocatalyst material causes a catalytic reaction by the ultraviolet rays emitted from the light source 144, thereby oxidizing and / or decomposing various pollutants, bacteria and the like in the air in contact with the photocatalyst.

The photocatalyst material may include a material that provides a photocatalytic reaction as a photocatalytic medium. For example, the photocatalytic medium can be 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) Zinc oxide (ZnO2), tin oxide (SnO2), or the like can be used. The hydroxyl radical formed by the photocatalytic reaction of the photocatalyst material can perform a sterilizing action by acting as a strong oxidizer and oxidize and decompose organic pollutants in the air to decompose contaminants and odor substances in the air introduced into the trapper 1000 Which can be converted to water and carbon dioxide. Carbon dioxide generated at this time has a mosquito inducing effect, which may increase the attracting effect on the mosquito.

In the case where the captor 1000 is coated with a photocatalyst material, the PCB 143 may further include a light source 144 for emitting light in a wavelength band that reacts with the photocatalyst material. For example, some of the plurality of light sources mounted on the PCB 143 may be arranged to irradiate ultraviolet rays of a wavelength band having a large insect attracting effect, while the other part may be arranged to irradiate ultraviolet rays of a wavelength band reacting with the photocatalyst material. However, it is to be understood that only one type of light source can be used if the ultraviolet rays to be emitted have an insect attracting effect and a photocatalytic reaction effect.

FIG. 18 shows a cross section of a light source 144 according to an embodiment of the present application, and FIG. 19 shows a cross-sectional view taken along the perforated line A-B-B'-A 'of FIG.

18 and 19, a light source 144 according to an embodiment of the present invention includes a first conductivity type semiconductor layer 1111, a mesa structure including an active layer 1112 and a second conductivity type semiconductor layer 1113, And may further include a growth substrate 1100 and a second electrode 1120. The growth substrate 1100 may include a first insulating layer M, a first insulating layer 1130, a first electrode 1140, and a second insulating layer 1150, .

The growth substrate 1100 is not limited as long as it can grow the first conductivity type semiconductor layer 1111, the active layer 1112 and the second conductivity type semiconductor layer 1113. For example, the growth substrate 1100 may be a sapphire substrate, A carbide substrate, a gallium nitride substrate, an aluminum nitride substrate, a silicon substrate, or the like. The side surface of the growth substrate 1100 may include an inclined surface, so that the extraction of the light generated in the active layer 1112 can be improved.

The first conductivity type semiconductor layer 1111, the active layer 1112 and the second conductivity type semiconductor layer 1113 may include a III-V compound semiconductor, for example, (Al, Ga, In) N Based semiconductor, for example. The first conductivity type semiconductor layer 1111 may include an n-type impurity (for example, Si)

The second conductivity type semiconductor layer 1113 may include a p-type impurity (e.g., Mg). It may also be the opposite. The active layer 1112 may comprise a multiple quantum well structure (MQM). When a forward bias is applied to the light source 144, electrons and holes are combined with each other in the active layer 1112 to emit light. The first conductivity type semiconductor layer 1111, the active layer 1112 and the second conductivity type semiconductor layer 1113 may be formed on a growth substrate (not shown) using techniques such as metal organic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE) 1100). ≪ / RTI >

[

The first conductivity type semiconductor layer 1111 may include a first contact region R 1 and a second contact region R 2 exposed through the mesa M. [ Since the mesa M is formed by removing the active layer 1112 and the second conductivity type semiconductor layer 1113 disposed on the first conductivity type semiconductor layer 1111, Type semiconductor layer 1111 is exposed. The first electrode 1140 may be electrically connected to the first conductivity type semiconductor layer 1111 by making contact with the first contact region Rl and the second contact region R2. The first contact region R1 may be disposed around the mesa M along the periphery of the first conductivity type semiconductor layer 1111 and specifically between the mesa M and the side of the light source 144, And may be disposed along the upper surface of the conductive semiconductor layer. The second contact region R2 may be at least partially surrounded by the mesa M. [

The length of the second contact region R2 in the major axis direction may be 0.5 times or more the length of one side of the light source 144. [ In this case, since the region where the first electrode 1140 and the first conductivity type semiconductor layer 1111 are in contact with each other can be increased, the current flowing from the first electrode 1140 to the first conductivity type semiconductor layer 1111 can be more effectively So that the forward voltage can be further reduced.

The second electrode 1120 is disposed on the second conductivity type semiconductor layer 1113 and can be electrically connected to the second conductivity type semiconductor layer 1113. The second electrode 1120 is formed on the mesa M and may have the same shape according to the shape of the mesa M. [ The second electrode 1120 includes a reflective metal layer 1121 and may further include a barrier metal layer 1122 and the barrier metal layer 1122 may cover the top and sides of the reflective metal layer 1121. The barrier metal layer 1122 may be formed to cover the upper surface and the side surface of the reflective metal layer 1121 by forming a pattern of the reflective metal layer 1121 and forming the barrier metal layer 1122 thereon. For example, reflective metal layer 1121 may be formed by depositing and patterning Ag, Ag alloy, Ni / Ag, NiZn / Ag, and TiO / Ag layers.

The barrier metal layer 1122 may be formed of Ni, Cr, Ti, Pt, Au or a composite layer thereof. Specifically, the barrier metal layer 1122 may be formed of Ni / Ag / [Ni / Ti] 2 / Au / Ti. More specifically, at least a part of the upper surface of the second electrode 1120 may include a Ti layer having a thickness of 300 ANGSTROM. The adhesion between the first insulating layer 1130 and the second electrode 1120 is improved so that the reliability of the light source 144 is improved Can be improved.

The electrode protection layer 1160 may be disposed on the second electrode 1120 and the electrode protection layer 1160 may be formed of the same material as the first electrode 1140 but is not limited thereto.

The first insulating layer 1130 may be disposed between the first electrode 1140 and the mesa M. The first electrode 1140 and the mesa M may be insulated through the first insulating layer 1130 and the first electrode 1140 and the second electrode 1120 may be insulated. The first insulating layer 1130 may partially expose the first contact region Rl and the second contact region R2. The first insulating layer 1130 may expose a portion of the second contact region R2 through the opening 1130a and the first insulating layer 1130 may expose a portion of the first conductive semiconductor layer 1111 At least a part of the first contact region R1 may be exposed, covering only a part of the first contact region R1 between the outer periphery and the mesa M.

The first insulating layer 1130 may be disposed on the second contact region R2 along the outline of the second contact region R2. At the same time, the first insulating layer 1130 may be disposed adjacent to the mesa M rather than a region where the first contact region R 1 and the first electrode 1140 are in contact with each other.

The first insulating layer 1130 may have an opening 1130b for exposing the second electrode 1120. [ The second electrode 1120 can be electrically connected to the pad or the bump through the opening 1130b.

A region where the first contact region R 1 and the first electrode 140 are in contact is disposed along the entire outer periphery of the upper surface of the first conductivity type semiconductor layer. The first contact region R 1 and the first electrode 1140 may be arranged so as to be adjacent to all four sides of the first conductivity type semiconductor layer 1111 and completely surround the mesa M, . In this case, since the region where the first electrode 1140 and the first conductivity type semiconductor layer 1111 are in contact with each other can be increased, the current flowing from the first electrode 1140 to the first conductivity type semiconductor layer 1111 can be more effectively So that the forward voltage can be further reduced.

In one embodiment of the present application, the first electrode 1140 and the second electrode 1120 of the light source 144 may be mounted on the PCB 143 directly or through a pad.

For example, the pad may be solder or eutectic metal, but is not limited thereto. For example, AuSn may be used as the eutectic metal.

Alternatively, when the light source 144 is directly mounted on the PCB 143, the first electrode 1140 and the second electrode 1120 of the light source 144 may be directly bonded to the PCB 143. In this case, the bonding material may include an adhesive material having a conductive property. For example, the bonding material may include at least one of silver (Ag), tin (Sn), and copper (Cu).
