One embodiment of the present invention relates to a fluid processing device. In an embodiment, the fluid is a target substance to be treated with the fluid treatment device, and the fluid may be water (particularly, running water) or air. In an embodiment, treating the fluid means performing an operation such as sterilizing, purifying, deodorizing, etc. on the fluid by the fluid treatment device. However, in an embodiment of the present invention, the processing of the fluid is not limited thereto, and includes other operations performed by a fluid processing apparatus described later.

Referring to fig. 1 to 3, a fluid treatment apparatus according to an embodiment of the present invention includes: a pipe 100 into which a fluid flows; the light source module 200 supplies light to the fluid in the pipe 100.

The pipe 100 is provided in a rod shape extending long in one direction, and an internal space for processing a fluid is provided inside the pipe. The direction in which the pipe 100 extends is hereinafter referred to as the direction in which the pipe 100 extends or the longitudinal direction of the pipe 100.

The pipe 100 has an inlet 113 for allowing a fluid to flow therein and an outlet 135 for discharging a treated fluid.

In an embodiment of the present invention, the cross-sections of the inflow port 113 and the discharge port 135 may have a circular shape or an elliptical shape, but are not limited thereto, and may be provided in various shapes, such as a polygon. Here, the cross sections of the inlet 113 and the outlet 135 may be cross sections in a direction intersecting with a direction in which the inlet 113 extends or a direction in which a flow path is formed.

Although not shown, a separate pipe may be provided at the inlet 113 and/or the outlet 135. Separate pipes may be connected to the inlet 113 and the outlet 135 by means of nozzles. The nozzle may be coupled to the inflow port 113 and/or the discharge port 135 in various ways, for example, may be screw-coupled.

In the present embodiment, although the case where the outer tube main body 111 and the inner tube main body 121 extend only in one direction is illustrated, the present invention is not limited thereto, and a part of the outer tube main body 111 and the inner tube main body 121 may be curved (bending). The degree of bending or the number of times of bending of the body may be variously changed according to the embodiment.

The light source module 200 provides light to the fluid suitable for treating the fluid. The light source module 200 is disposed at various positions adjacent to the fluid, and for convenience of explanation, a case of being disposed outside the pipe 100 is illustrated as an example. Such a diagram of the light source module 200 in the present embodiment is an example, and it should be explained that the emphasis is on providing light into the pipe 100, and the position of the light source module 200 is not limited thereto. Actually, the light source module 200 may be mounted outside the pipe 100 as shown in the figure, or may be mounted inside the pipe 100 differently from this. Various positions of the light source module 200 are described in the following embodiments.

The piping 100 includes an outer pipe 110 disposed outside and an inner pipe 120 disposed inside the outer pipe 110. Accordingly, the internal space of the pipe 100 is divided into: a first inner space 101 defined as the outside of the inner pipe 120 while being inside the outer pipe 110; and a second inner space 102 defined as an inner side of the inner tube 120.

The outer tube 110 includes an outer tube main body 111 extending in one direction and an inflow port 113 provided at one end of the outer tube main body 111. When both ends of the outer tube 110 in the longitudinal direction are referred to as a first end 111a and a second end 111b, the inlet 113 is disposed adjacent to either one of the first end 111a and the second end 111 b. In an embodiment of the present invention, a case where the inlet 113 is disposed on the first end 111a side is illustrated as an example.

The outer tube main body 111 may have a tube shape with a hollow inside, and a shape with both ends open in the extending direction. In one embodiment of the present invention, the outer tube body 111 may be cylindrical in shape. In this case, the cross section intersecting the longitudinal direction of the cylinder is circular in shape. However, the cross-sectional shape of the body is not limited thereto, and various shapes such as a polygon like an ellipse or a quadrangle may be provided.

The outer tube 110 may be formed of a material having a high reflectance and/or a metal having a high thermal conductivity so that light emitted from the light source module 200 is reflected well inside the pipe 100. For example, the outer tube 110 may be formed using a material having a high reflectance, such as stainless steel, aluminum, or magnesium oxide, or a material having a high thermal conductivity, such as stainless steel, aluminum, silver, gold, copper, or an alloy thereof. The metal having high thermal conductivity can efficiently discharge heat that may be generated in the pipe 100 to the outside.

However, the material of the outer tube 110 is not limited thereto, and in the case where the light source module 200 is disposed outside the outer tube 110, at least a portion thereof may be formed of a material that transmits light so that the light emitted from the light source module 200 can reach the fluid inside the outer tube 110. For example, the entire outer tube 110 is made of a transparent material, or a portion adjacent to the light source module 200 is made of a transparent material, so that light from the light source module 200 can reach the fluid. In the case where the outer tube 110 is made of a transparent material, the transmission member may be made of quartz or a polymer organic material. Here, the wavelength of absorption/transmission of the polymer organic material differs depending on the kind of the monomer, the molding method, and the conditions, and therefore, the wavelength can be selected in consideration of the wavelength emitted from the light source. For example, organic polymers such as poly (methyl methacrylate) (PMMA), polyvinyl alcohol (PVA), polypropylene (PP), and low density Polyethylene (PE) hardly absorb ultraviolet rays, whereas organic polymers such as polyester (polyester) may absorb ultraviolet rays. However, the transmission member may be formed using a plurality of materials other than the above materials, and the material thereof is not limited thereto.

The inflow port 113 may be connected to one side of the outer tube main body 111 to be connected to the first inner space 101 inside the outer tube main body 111. The inflow port 113 may extend in a direction different from the direction in which the outer tube main body 111 extends. In an embodiment of the present invention, the extending direction of the inflow port 113 may be inclined or perpendicular to the extending direction of the outer tube main body 111, and accordingly, the fluid may move in the extending direction of the main body after flowing in the direction inclined or perpendicular to the outer tube main body 111. The fluid flowing into the outer tube main body 111 through the inflow port 113 is a target object that requires sterilization, purification, deodorization, and the like.

The inner tube 120 is disposed within the inner space defined by the outer tube 110.

The inner tube main body 121 may have a tube shape with a hollow inside, and a shape with both ends open in the extending direction. In one embodiment of the present invention, the inner tube body 121 may be cylindrical in shape. In this case, the cross section intersecting the longitudinal direction of the cylinder is circular in shape. However, the cross-sectional shape of the inner tube main body 121 is not limited thereto, and various shapes such as a polygon such as an ellipse and a quadrangle may be provided.

At least a portion of the material of the inner tube 120 may be formed of a material that transmits light so that the light emitted from the light source module 200 can reach the fluid inside the inner tube 120. For example, the inner tube 120 is entirely made of a transparent material, or a portion adjacent to the light source module 200 is made of a transparent material, so that light from the light source module 200 can reach the fluid.

In an embodiment of the present invention, the outer tube 110 and the inner tube 120 may all have a cylindrical shape. However, the shapes of the outer tube 110 and the inner tube 120 are not limited thereto, and the shapes of the outer tube 110 and the inner tube 120 may be different from each other. Also, the centers of the outer tube 110 and the inner tube 120 in cross section may coincide with each other, such as concentric circles, etc., but not limited thereto, the centers of the outer tube 110 and the inner tube 120 may not coincide.

When both ends in the longitudinal direction of the inner tube 120 are referred to as a first end 121a and a second end 121b, an opening 123 penetrating an inner space and an outer space of the inner tube 120 is provided in one of the first end 121a and the second end 121b of the inner tube 120. The opening 123 is provided on the opposite side of the outer tube 110 from the side where the inflow port 113 is formed. That is, in the case where the first end portion 111a of the outer tube 110 and the first end portion 121a of the inner tube 120 are arranged on the same side, the inflow port 113 is provided on the first end portion 111a side of the outer tube 110, and the opening 123 is provided on the second end portion 121b side of the inner tube 120.

The inner tube 120 is provided with a discharge port 135 on the first end 121a side. The discharge port 135 may have the same direction as the extending direction of the inner tube 120, and may penetrate through the first base 130 described later to connect the second internal space 102 and the outside.

Accordingly, the fluid flows into the first internal space 101 of the pipe 100 through the inlet 113, sequentially flows from the first end 111a to the second end 111b of the pipe 100, and then moves to the second internal space 102 through the opening 123 of the inner pipe 120. The fluid moved to the second internal space 102 is discharged to the outside of the pipe 100 through the discharge port 135. Thus, the fluid flows in the first internal space 101 in one direction along the extending direction of the outer pipe 110, and sequentially flows in the second internal space 102 in the opposite direction to the one direction along the extending direction of the outer pipe 110 of the inner pipe 120, and the moving path of the fluid in the pipe 100 becomes long. Since the fluid has a long moving path within the piping 100, as a result, the fluid is exposed to the light from the light source module for a long time, the accumulation amount of the light applied to the fluid is increased, and the fluid treatment efficiency is also improved.

In one embodiment of the present invention, the inlet 113 and the outlet 135 may be set to have different sizes in order to control the speed of the fluid moving inside the pipe 100. In the case where the fluid velocity in the inflow port 113 is different from the fluid velocity in the discharge port 135, the residence time of the fluid in the pipe 100 can be increased.

For this reason, the inner diameter D1 of the inflow port 113 and the inner diameter D2 of the discharge port 135 may be set to different sizes from each other. For example, the inner diameter D1 of the inlet 113 may be greater than the inner diameter D2 of the outlet 135, and in one embodiment of the invention, the ratio of the diameter D1 of the inlet 113 to the diameter D2 of the outlet 135 may be about 2: 1. In the case where the inner diameter D1 of the inflow port 113 is larger than the inner diameter D2 of the discharge port 135, resistance is applied to the fluid to be discharged to the outside due to the smaller diameter of the discharge port 135. Accordingly, the velocity of the fluid at the discharge port 135 is slower than the velocity at the inflow port 113. When the fluid velocity at the inlet 113 is referred to as a first velocity and the fluid velocity at the outlet 135 is referred to as a second velocity, the second velocity is smaller than the first velocity. Accordingly, the resistance in the discharge port 135 causes the fluid not to be discharged at a fast speed, and causes the residence time of the fluid in the pipe 100 to increase. An increase in the residence time of the fluid means that the fluid will be exposed to light emitted from the light source module 200 described later for a longer time. The longer the exposure to the light emitted from the light source module 200, the more the fluid accumulates the irradiated light below the predetermined amount, resulting in an increase in the treatment efficiency of the fluid.

Further, in addition to the inflow port 113 and the discharge port 135, the diameter D3 of the opening 123 of the inner tube 120 may be set to be the same as or different from the inner diameter of the inflow port 113 and/or the discharge port 135 to increase the internal residence time of the fluid. For example, the diameter D3 of the opening 123 of the inner tube 120 may be smaller than the diameter D1 of the inflow port 113. In this case, the fluid flowing in from the inlet 113 at the first speed moves into the inner pipe 120 at a speed lower than the first speed due to the small diameter of the opening 123, whereby the residence time of the fluid in the pipe 100 can be increased. In one embodiment of the present invention, the diameter D3 of opening 123 may have various values. In an embodiment of the present invention, the diameter D3 of the opening 123 may have a smaller value than the discharge opening 135, or may have a smaller value than the inflow opening 113, or may have substantially the same value as the discharge opening 135. However, the ratio of the diameters of the inlet 113, the outlet 135, and the opening 123 is not limited to this, and may be set differently in order to extend the residence time.

Here, in the case of reducing the diameter of the inner tube 120 or the outer tube 110 as a whole, the overall velocity of the fluid is significantly reduced, so that the exposure time to the light from the light source module 200 can be extended. However, in this case, the flow rate that the fluid treatment device can treat is also significantly reduced, and therefore it is not preferable to unconditionally reduce the diameter of the inner tube 120 or the outer tube 110 as a whole. In one embodiment of the present invention, there is an advantage in that a large amount of fluid can be efficiently processed by increasing the residence time of the fluid in the pipe 100 as an actual processing region while maintaining the average diameter of the inner pipe 120 or the outer pipe 110 to enable a sufficient flow rate to be processed.

A first base 130 and a second base 140 are fastened to the first end 111a and the second end 111b of the outer tube main body 111 and the first end 121a and the second end 121b of the inner tube main body 121, respectively. In an embodiment of the present invention, the first and

second bases

130 and 140 may have fastening portions coupled to the outer tube body 111 or the inner tube body 121.

The fastening portion may be provided in various forms. For example, the first and

second bases

130 and 140 may include an insertion portion having a diameter corresponding to the inner diameter of the inner tube body 121 or the outer tube body 111 as a fastening portion, and may be inserted into and fastened to an end portion of the inner tube body 121 or the outer tube body 111, thereby sealing the inner tube body 121 or the outer tube body 111.

Specifically, the first base 130 is provided at the first end 111a of the outer tube main body 111 and the first end 121a of the inner tube main body 121, and is fastened to the outer tube main body 111 and the inner tube main body 121. The first seat 130 is formed with stepped portions having different outer diameters from each other so as to be insertedly fastened to the outer tube 110 and the inner tube 120. For example, the first base 130 may be provided such that a portion facing the first end 111a of the outer tube 110 has an outer diameter corresponding to an inner diameter of the outer tube 110, and a screw 131 rotatably inserted into the first end 111a of the outer tube 110 is provided at one side of the first base 130. The inner surface of the first end 111a of the outer tube 110 may be provided with a screw thread 111s corresponding to the screw thread 131 of the first base so as to be capable of being fastened to each other by being engaged with each other.

Also, a portion of the first base 130 facing the first end 121a of the inner tube 120 has an outer diameter corresponding to an inner diameter of the inner tube 120, and has an insertion protrusion 133 inserted into the second end 111b of the inner tube 120. The insertion projection 133 is formed with a through hole parallel to the extending direction of the inner tube 120 and passing through the center of the first base 130, and the through hole serves as a discharge port 135 through which the fluid is discharged to the outside.

The second base 140 is provided at the first end 111a of the outer tube main body 111 and the second end 121b of the inner tube main body 121, and is fastened to the outer tube main body 111 and the inner tube main body 121. The second base 140 is also formed with stepped portions having different outer diameters from each other so as to be insertedly fastened to the outer tube 110 and the inner tube 120.

In the second base 140, a portion facing the first end 111a of the outer tube 110 has an outer diameter corresponding to an inner diameter of the outer tube 110, and has a screw 141 rotatably inserted into the second end 111b of the outer tube 110. A screw thread 111s corresponding to the screw thread 141 of the second base 140 may be provided on an inner surface of the second end portion 111b of the outer tube 110 so as to be capable of being fastened to each other by being engaged with each other.

Also, a portion of the second base 140 facing the second end portion 121b of the inner tube 120 has an outer diameter corresponding to an inner diameter of the inner tube 120, and has an insertion protrusion 133 inserted into the second end portion 121b of the inner tube 120. The insertion projection 133 of the second base 140 is not provided with a through hole.

The first and

second bases

130 and 140 may be made of various materials, and the material is not particularly limited. In an embodiment of the present invention, the first base 130 and the second base 140 may be made of a material (e.g., metal) that is easy to conduct heat. When the first and

second bases

130 and 140 are made of a material that easily conducts heat, heat generated from the light source can be easily discharged to the outside through the cover. As a result, deterioration of the light source due to heat generated at the light source is prevented, thereby improving reliability of the fluid treatment apparatus while exhibiting a stable sterilization effect.

In the fluid treatment apparatus according to an embodiment of the present invention, one or more sealing members for tightly fastening the inner pipe 120 or the outer pipe 110 to the first base 130 and the second base 140 while preventing fluid from leaking to other regions may be provided.

In an embodiment of the present invention, the sealing member may include a first outer sealing member 151a disposed between the first base 130 and the first end 111a of the outer tube 110 and a second outer sealing member 151b disposed between the second base 140 and the second end 111b of the outer tube 110. Also, the sealing member may include a first inner sealing member 153a disposed between the first base 130 and the first end 121a of the inner tube 120 and a second inner sealing member 153b disposed between the second base 140 and the second end 121b of the inner tube 120.

The first and second outer sealing

members

151a and 151b tightly fasten the outer tube 110 and the first and

second bases

130 and 140, and prevent the fluid in the first internal space 101 from leaking to the outside through between the outer tube 110 and the first and

second bases

130 and 140. The first and second

inner seal members

153a and 153b tightly fasten the inner tube 120 to the first and

second bases

130 and 140, and prevent fluid from leaking to a region other than the opening 123 (e.g., to the outside through a gap between the outer tube 110 and the first and second bases 130 and 140). The sealing member may be provided singly or in plurality.

The sealing member has a closed figure (closed figure) shape so that the inside and the outside of the main body of the pipe 100 can be tightly fastened and separated to seal the two regions when the first and

second bases

130 and 140 are fastened to the outer and

inner pipes

110 and 120. For example, the first and second outer sealing

members

151a and 151b and the first and second

inner sealing members

153a and 153b may have an O-ring (O-ring) shape.

The sealing member may be formed using an elastic material having flexibility. In the case where the sealing member is formed of an elastic material, the fastening pipe 100 main body is compressed when the outer pipe 110 or the inner pipe 120 and the first and

second bases

130 and 140 are fastened to each other, thereby maintaining a tight fastening structure.

The elastic material constituting the sealing member may be silicone, but is not limited thereto and may be constituted by other materials. For example, natural or synthetic rubber may be used as the elastic material, and other high molecular organic elastic materials may be used.

The light source module 200 emits light. The light source module 200 may include a substrate 220 and a light emitting element 210 mounted on the substrate 220.

The substrate 220 may be provided in a form extending long in a predetermined direction (e.g., one direction). A plurality of light emitting elements 210 may be arranged in a predetermined direction (e.g., the one direction) on the substrate 220.

In the case where the light source module 200 includes a plurality of light emitting elements 210, the light emitting elements 210 may emit light of the same wavelength band or light of wavelength bands different from each other. For example, in one embodiment, the light emitting elements 210 may all emit light in the same or similar ultraviolet band. In another embodiment, a portion of the light emitting elements 210 may emit a portion of the ultraviolet band and the remaining light emitting elements 210 may emit a portion of the remaining ultraviolet band.

In the case where the light emitting elements 210 have different wavelength bands from each other, the light emitting elements 210 may be arranged in various orders. For example, the light emitting elements 210 emitting light of a first wavelength band and the light emitting elements 210 emitting light of a second wavelength band different from the first wavelength band may be alternately arranged.

The light emitted from the light source module 200 may have various wavelength bands. The light from the light source module 200 may be light in a visible light band, light in an infrared light band, or light in other bands. In an embodiment of the present invention, the light emitted from the light source module 200 may have various wavelength bands according to the kind of fluid, an object to be processed (e.g., bacteria, germs, etc.), etc., and particularly, in the case of sterilizing the fluid, may have a sterilization wavelength band. For example, the light source module 200 may emit light in an ultraviolet band. In an embodiment of the present invention, the light source module 200 may emit light of a wavelength band of about 100nm to about 405nm, which is a wavelength band capable of sterilizing microorganisms and the like. The light source module 200 may emit light in a wavelength band of about 100nm to about 280nm in one embodiment of the present invention, 180nm to about 280nm in another embodiment, and 250nm to about 260nm in yet another embodiment. The ultraviolet rays of the wavelength band may have a strong sterilizing power, for example, at every 1cm²When ultraviolet rays are irradiated at an intensity of 100. mu.W, about 99% of bacteria such as Escherichia coli, diphtheria bacteria and dysentery can be killed. And, the ultraviolet rays of the wavelength band can kill bacteria causing food poisoning, and thus can kill pathogenic escherichia coli, Staphylococcus aureus (Staphylococcus aureus), Salmonella wegener (Salmonella welterdenum), Salmonella typhimurium (s. typhimurium), Enterococcus faecalis (Enterococcus faecium), Bacillus cereus (Bacillus cereus), Pseudomonas aeruginosa (Pseudomonas aeruginosa), Vibrio parahaemolyticus (Vibrio parahaemolyticus), Listeria monocytogenes (Listeria monocytogenes), Yersinia enterocolitica (Yersinia enterocolitica), Clostridium perfringens (Clostridium perfringens), Clostridium botulinum (Clostridium botulinum), Campylobacter jejunii (Campylobacter jejunii) or Enterobacter jejunii (Enterobacter jejunii) causing food poisoning.

In an embodiment of the present invention, the light emitted from the light source module 200 may have various wavelength bands, and at least a portion of the light source module 200 may include a material that causes a catalytic reaction by the light emitted from the light source module 200. For example, a photocatalytic layer made of a photocatalytic material may be provided on all or a part of at least one of the inner circumferential surface and/or the outer circumferential surface of the outer tube 110 and the inner tube 120 of the present invention. The region where the photocatalytic layer is provided is not particularly limited as long as it is a region that can be reached by light from the light source module 200.

A photocatalyst is a material that is irradiated with light to cause a catalytic reaction. The photocatalyst may react with light of various wavelength bands depending on the material constituting the photocatalyst. In an embodiment of the present invention, a material that causes a photocatalytic reaction with light of an ultraviolet band among light of a plurality of bands may be used, and this will be described. However, the kind of the photocatalyst is not limited thereto, and other photocatalysts having the same or similar mechanism according to the light emitted from the light source may be used.

The photocatalyst is activated by ultraviolet rays to cause a chemical reaction, and various pollutants, bacteria, and the like in the fluid in contact with the photocatalyst are decomposed by an oxidation-reduction reaction.

When a photocatalyst is exposed to light above band gap energy, a chemical reaction is induced that generates electrons and holes. Accordingly, compounds within the fluid, such as water or organic matter, may be decomposed by hydroxyl radicals (Hydroxy radicals) and Superoxide ions (Superoxide Ion) formed by the photocatalytic reaction. Hydroxyl radicals are substances with very strong oxidizing power, which decompose pollutants in the fluid or kill bacteria. Such a photocatalyst material may be titanium oxide (TiO)₂) Zinc oxide (ZnO), tin oxide (SnO)₂) And so on. In an embodiment of the present invention, since the recombination rate of holes and electrons generated on the surface of the photocatalyst is very fast, it is limited to use it in a photochemical reaction, so that metals such as Pt, Ni, Mn, Ag, W, Cr, Mo, Zn, etc., or oxides thereof may be added to delay the recombination rate of holes and electrons. In the case where the recombination rate of holes and electrons is delayed, the possibility of contact with the target substance to be oxidized and/or decomposed increases, and as a result, the degree of reaction can be increased. By utilizing the photocatalytic reaction, sterilization, purification, deodorization, and the like can be performed on the fluid. In particular, inIn the case of sterilization, since sterilization or antibacterial action can be exerted by destroying enzymes in bacterial cells, enzymes acting on the respiratory system, and the like, the released toxins can be decomposed while preventing the growth of bacteria or mold.

In one embodiment of the invention, the photocatalyst acts as a catalyst only and does not change itself, and thus can be used semi-permanently, as long as the corresponding light is provided, the effect can be semi-permanently sustained.

Although not shown, the fluid treatment apparatus according to an embodiment of the present invention may further include a driving circuit connected to the light source module 200. The driving circuit supplies power to at least one light source module 200. For example, the driving circuit may be disposed in a fluid control device including two light source modules 200, and then power may be independently supplied to the two light source modules 200. Therefore, it is possible to realize selective driving of simultaneously turning on or off two light source modules 200, or turning on one and turning off the other, and the like.

Detailed Description

The light emitting element 210 may be provided in various forms, and fig. 4a and 4b are cross-sectional views illustrating an embodiment of the light emitting element, which illustrates a case where the light emitting element is implemented as a light emitting diode.

The light emitting diode may be configured in various forms such as a vertical type or a flip type, and fig. 4a illustrates a vertical type light emitting diode and fig. 4b illustrates a flip type light emitting diode. However, the structure of the light emitting diode is not limited thereto, and the following drawings should be understood as an embodiment of the present invention.

Referring to fig. 4a, the light emitting diode includes a first conductive type semiconductor layer 2111, an active layer 2112, and a second conductive type semiconductor layer 2113. A substrate 2100 serving as a first electrode, an adhesive layer 2101, and a reflective layer 2109 may be provided below the first conductive type semiconductor layer 2111 of the light-emitting diode, and a second electrode 2120 may be provided above the second conductive type semiconductor layer 2113.

The substrate 2100 may be formed of a conductive material, and may be formed of Si, GaAs, GaP, AlGaINP, Ge, SiSe, GaN, AlInGaN, InGaN, or a single metal or an alloy thereof of Al, Zn, Ag, W, Ti, Ni, Au, Mo, Pt, Pd, Cu, Cr, or Fe.

The second conductive type semiconductor layer 2113 may be disposed on the first conductive type semiconductor layer 2111, and the active layer 2112 may be disposed between the first conductive type semiconductor layer 2111 and the second conductive type semiconductor layer 2113. The first conductive type semiconductor layer 2111, the active layer 2112, and the second conductive type semiconductor layer 2113 may include a group iii-v compound semiconductor, for example, a nitride-based semiconductor such as (Al, Ga, In) N. The first conductive type semiconductor layer 2111 may include a first conductive type impurity (e.g., Si), and the second conductive type semiconductor layer 2113 may include a second conductive type impurity (e.g., Mg). The reverse may be also possible.

In one embodiment of the present invention, the first conductive type semiconductor layer 2111 may be subjected to roughening treatment. Therefore, light generated from the active layer 2112 can be reflected at the interface after the roughening treatment.

In an embodiment of the invention, a reflective layer 2109 may be interposed between the first conductive type semiconductor layer 2111 and the light source substrate 2110. The reflective layer 2109 may be formed using a metal substance having a high reflectance, such as silver (Ag) or aluminum (Al), or may be formed using another metal having a high reflectance or an alloy thereof.

An adhesive layer 2101 may be interposed between the reflective layer 2109 and the light source substrate 2110, and the adhesive layer 2101 may improve the adhesion between the light source substrate 2110 and the reflective layer 2109 to prevent the light source substrate 2110 from separating from the reflective layer 2109. Further, although not shown, a diffusion preventing layer may be interposed between the adhesive layer 2101 and the reflective layer 2109. The diffusion preventing layer can prevent the metal element from diffusing from the adhesive layer 2109 or the light source substrate 2110 to the reflective layer 2109, thereby maintaining the reflectivity of the reflective layer 2109.

A second electrode 2120 is disposed on the second conductive type semiconductor layer 2113. Accordingly, the light source substrate 2110 and the second electrode 2120 serving as first electrodes supply current to the first conductive type semiconductor layer 2111 and the second conductive type semiconductor layer 2113, and light can be emitted.

Referring to fig. 4b, the light emitting diode according to an embodiment of the present invention may include a first conductive type semiconductor layer 2111, a mesa M including an active layer 2112 and a second conductive type semiconductor layer 2113, first insulating

layers

2130a and 2130b, a first electrode 2140 and a second insulating layer 2150, and may include a substrate 2100 and a second electrode 2120.

The substrate 2100 is not limited as long as it is a substrate 220 on which the first conductive type semiconductor layer 2111, the active layer 2112, and the second conductive type semiconductor layer 2113 can be grown, and examples thereof include a sapphire substrate 220, a silicon carbide substrate 220, a gallium nitride substrate 220, an aluminum nitride substrate 220, and a silicon substrate 220. The side surface of the substrate 2100 may include an inclined surface, and thus extraction of light generated at the active layer 2112 can be improved.

The second conductive type semiconductor layer 2113 may be disposed on the first conductive type semiconductor layer 2111, and the active layer 2112 may be disposed between the first conductive type semiconductor layer 2111 and the second conductive type semiconductor layer 2113. The first conductive type semiconductor layer 2111, the active layer 2112, and the second conductive type semiconductor layer 2113 may include a group iii-v compound semiconductor, for example, a nitride-based semiconductor such as (Al, Ga, In) N. The first conductive type semiconductor layer 2111 may include a first conductive type impurity (e.g., Si), and the second conductive type semiconductor layer 2113 may include a second conductive type impurity (e.g., Mg). The opposite is also possible. The active layer 2112 may include a multiple quantum well structure (MQM). When a forward bias is applied to the light emitting diode, electrons and holes are combined in the active layer 2112, and light is emitted. The first conductive type semiconductor layer 2111, the active layer 2112, and the second conductive type semiconductor layer 2113 can be grown on the substrate 2100 by a technique such as Metal Organic Chemical Vapor Deposition (MOCVD) or Molecular Beam Epitaxy (MBE).

The light emitting diode may include at least one mesa M including an active layer 2112 and a second conductive type semiconductor layer 2113. The table top M may include a plurality of protrusions, and the plurality of protrusions may be spaced apart from each other. The light emitting diode may also include a plurality of mesas M spaced apart from each other, without being limited thereto. The side surface of the mesa M may be formed obliquely using a photoresist reflow (photo resist reflow) or the like, and the oblique side surface of the mesa M can improve the light emitting efficiency generated in the active layer 212.

The first conductive type semiconductor layer 2111 is provided with a first contact region P1 and a second contact region P2 exposed through the mesa M. Since the mesa M is formed by removing the active layer 2112 and the second conductive type semiconductor layer 2113 disposed on the first conductive type semiconductor layer 2111, a portion other than the mesa M is a contact region of the exposed upper surface of the first conductive type semiconductor layer 2111. The first electrode 2140 is in contact with the first contact region P1 and the second contact region P2, and can be electrically connected to the first conductive semiconductor layer 2111. The first contact region P1 may be arranged around the mesa M along the periphery of the first conductive type semiconductor layer 2111, and in particular, may be arranged along the periphery of the upper surface of the first conductive type semiconductor layer between the mesa M and the side of the light emitting diode. At least a portion of the second contact region P2 may be surrounded by the mesa M.

The second electrode 2120 may be disposed on the second conductive type semiconductor layer 2113, and electrically connected to the second conductive type semiconductor layer 2113. The second electrode 2120 may be formed on the mesa M and have the same shape along the shape of the mesa M. The second electrode 2120 may include a reflective metal layer 2121 and may further include a barrier metal layer 2122, and the barrier metal layer 2122 may cover an upper surface and a side surface of the reflective metal layer 2121. For example, the reflective metal layer 2121 may be patterned and the barrier metal layer 2122 may be formed thereon, so that the barrier metal layer 2122 may be formed to cover the upper surface and the side surfaces of the reflective metal layer 2121. For example, the reflective metal layer 2121 may be formed by depositing and patterning a layer of Ag, Ag alloy, Ni/Ag, NiZn/Ag, TiO/Ag.

The barrier metal layer 2122 may be formed of Ni, Cr, Ti, Pt, Au, or a composite thereof, and specifically, Ni/Ag/[ Ni/Ti ] may be sequentially formed on the upper surface of the second conductive semiconductor layer 2113]2/Au/Ti formed composite layer, more specifically, at least a portion of the upper surface of the second electrode 2120 may include

A thick Ti layer. In contact with the first insulating layer in the upper surface of the second electrode 2120When the region is formed of a Ti layer, the adhesion between the first insulating

layers

2130a and 2130b and the second electrode 2120 can be improved, and the reliability of the light-emitting diode can be improved.

An electrode protection layer 2160 may be disposed on the second electrode 2120, and the electrode protection layer 2160 may be the same material as the first electrode 2140, but is not limited thereto.

The first insulating

layers

2130a, 2130b may be arranged between the first electrode 2140 and the mesa M. The first electrode 2140 and the mesa M may be insulated from each other by the first insulating

layers

2130a and 2130b, and the first electrode 2140 and the second electrode 2120 may be insulated from each other. The first insulating

layers

2130a and 2130b may partially expose the first and second contact regions P1 and P2. Specifically, the first insulating

layers

2130a and 2130b may expose a part of the second contact region P2 through the opening 2130a, and the first insulating

layers

2130a and 2130b may cover only a part of the first contact region P1 between the periphery of the first conductivity type semiconductor layer 2111 and the mesa M, thereby exposing at least a part of the first contact region P1.

The first insulating

layers

2130a, 2130b may be disposed along the periphery of the second contact region P2 on the second contact region P2. Meanwhile, the first insulating

layers

2130a, 2130b may be defined to be disposed in a manner more adjacent to the mesa M than a region where the first contact region P1 meets the first electrode 2140.

The first insulating

layers

2130a and 2130b may have an opening portion 2130b that exposes the second electrode 2120. The second electrode 2120 may be electrically connected to a pad or a bump through the opening 2130 b.

Although not shown, when viewed from a plane, a region where the first contact region P1 meets the first electrode 240 is disposed along the entire periphery of the upper surface of the first conductive type semiconductor layer 2111. Specifically, a region where the first contact region P1 meets the first electrode 2140 may be disposed adjacent to all of the four sides of the first conductive type semiconductor layer 2111, and may completely surround the mesa M. In this case, since the region where the first electrode 2140 and the first conductive type semiconductor layer 2111 are in contact with each other can be increased, a current flowing from the first electrode 2140 to the first conductive type semiconductor layer 2111 can be more effectively dispersed, and the forward voltage can be further reduced.

In an embodiment of the invention, the first electrode 2140 and the second electrode 2120 of the light emitting diode may be directly mounted on the substrate 220 or mounted on the substrate via a pad.

For example, in the case where the light emitting diode is mounted on the substrate 220 by pad bonding, two pads provided between the light emitting diode and the substrate 220 may be provided, and the two pads may be connected to the first electrode 2140 and the second electrode 2120, respectively. For example, the pads may be solder or Eutectic Metal (Eutectic Metal), but are not so limited. For example, AuSn may be used as a eutectic metal.

As another example, in the case where the light emitting diode is directly mounted on the substrate 220, the first electrode 2140 and the second electrode 2120 of the light emitting diode may be directly bonded (bonded) to a wiring on the substrate 220. In this case, the bonding substance may include an adhesive substance having conductivity. For example, the bonding substance may include at least one conductive material of silver (Ag), tin (Sn), and copper (Cu). However, this is merely illustrative, and the bonding substance may include a plurality of substances having conductivity.

The fluid treatment apparatus according to an embodiment of the present invention increases the time of exposure to the light from the light source module 200 by increasing the residence time of the fluid in the pipe 100, and as a result, improves the fluid treatment efficiency. For example, when the light from the light source module 200 is ultraviolet light and corresponds to a sterilization wavelength, the sterilization efficiency of the fluid is improved.

The fluid treatment apparatus according to an embodiment of the present invention may be modified into various forms in order to increase the residence time of the fluid within the outer tube 110.

Fig. 5a and 5b are cross-sectional views illustrating a fluid treatment apparatus according to another embodiment of the present invention. In the following embodiments, the points different from the above-described embodiments will be mainly described in order to avoid redundant description, and the portions not described are based on the above-described embodiments.

Referring to fig. 5a and 5b, in order to increase the residence time of the fluid in the pipe 100, the fluid treatment apparatus according to an embodiment of the present invention includes outer pipes 110 having different diameters from each other according to positions.

Referring to fig. 5a and 5b, a side of the first end 111a of the outer tube 110 close to the inflow port 113 and a side of the second end 111b far from the inflow port 113 may have different inner diameters from each other. For example, the outer tubes 110 may have different inner diameters from each other in the extending direction, rather than having a constant inner diameter.

At this time, a portion near the second end 111b may have a larger inner diameter than a portion near the first end 111 a. For example, if the inner diameter of a portion near the first end 111a in the extending direction of the outer tube 110 is referred to as R1 and the inner diameter of a portion near the second end 111b is referred to as R2, R1 may have a value smaller than R2. Also, the outer tube 110 may have a shape in which the diameter gradually increases from a portion near the first end 111a to a portion near the second end 111 b.

As shown in the drawing, in the case where the diameter of the outer tube 110 has a difference in diameter from the first end 111a toward the second end 111b, or the diameter gradually increases, the increase in diameter causes a decrease in the flow velocity of the fluid on the second end 111b side. The decrease in the flow rate of the fluid results in an increase in the residence time of the fluid in the outer tube 110. The residence time of the fluid is increased and thus the time during which the fluid is exposed to the light source from the light source module 200 is increased, with the result that the fluid treatment effect is improved.

In order to increase not only the residence time of the fluid in the outer tube but also the residence time of the fluid in the inner tube, the fluid treatment apparatus according to an embodiment of the present invention may be modified into various forms.

Referring to fig. 6a and 6b, in the inner tube 120, a side portion of the second end 121b close to the opening 123 and a side portion of the first end 121a far from the opening 123 may have different inner diameters from each other. For example, the inner tubes 120 may have different inner diameters from each other in the extending direction, rather than a constant inner diameter.

At this time, a portion near the first end 121a may have a larger inner diameter than a portion near the second end 121 b. For example, if the inner diameter of a portion near the second end 121b in the extending direction of the inner tube 120 is referred to as r1, and the inner diameter of a portion near the first end 121a is referred to as r2, r1 may have a value smaller than r 2. Also, the inner tube 120 may have a shape in which the diameter gradually increases from a portion near the second end 121b to a portion near the first end 121 a.

As shown in the drawing, in the case where the diameter of the inner tube 120 has a difference in diameter from the second end 121b toward the first end 121a, or the diameter gradually increases, the increase in diameter causes a decrease in the flow velocity of the fluid on the first end 121a side. The reduced flow rate of the fluid results in an increased residence time of the fluid within the inner tube 120. The residence time of the fluid is increased and thus the time during which the fluid is exposed to the light source from the light source module 200 is increased, with the result that the fluid treatment effect is improved.

The above-described embodiment illustrates a case where the shape of the outer tube 110 or the inner tube 120 is deformed, but is not limited thereto. For example, the shapes of the outer tube 110 and/or the inner tube 120 may be variously combined within the scope of the concept of the present invention within a range that does not conflict. The outer tube 110 or the inner tube 120 may have a different shape as long as the shape can reduce the velocity of the fluid differently according to the region.

Fig. 7 is a sectional view illustrating a fluid treatment apparatus according to an embodiment of the present invention, illustrating a case where the fluid treatment apparatus has an inner tube having a different shape from the above-described embodiment.

Referring to fig. 7, the inner tube 120 of the fluid treatment device may have a curved shape that enables the fluid to stay for a long time within the inner tube 120. The curved shape means that the inner tube 120 is bent or bent more than once. The curved shape is not particularly limited, and may be, for example, a shape meandering into a spiral shape. The inner tube 120 has a curved shape so that the wall of the inner tube 120 may act as a resistance when the fluid moves, with the result that the flow rate of the fluid moving within the inner tube 120 can be reduced. The decrease in the flow rate of the fluid in the inner tube 120 causes the residence time of the fluid to increase, resulting in an increase in the time of exposure to the light from the light source module 200.

According to an embodiment of the present invention, the position of the light source module providing light to the fluid in the inner tube may be variously changed.

Referring to fig. 8, the outer tube 110 has a light source opening 115 formed by removing a portion thereof. The light source module 200 is mounted in the light source opening 115.

The light source opening 115 may be formed long in the extending direction of the outer tube 110 and provided in correspondence with the shape of the light source module 200 so that light from the light emitting element 210 of the light source module 200 reaches the fluid inside the pipe 100 as much as possible. For this reason, the side wall of the light source opening 115 may be inclined toward the inside in a wider form so as not to interfere with the light path from the light source module 200.

The light source module 200 may include a substrate 220 and a light emitting element 210 attached to the substrate 220, in addition to which a transmission window 230 through which light from the light emitting element 210 can be transmitted into the piping 100 is disposed.

In an embodiment of the present invention, in order to minimize the loss of the ultraviolet rays due to the total reflection, a surface of the substrate 220 facing the inside of the pipe 100 may be coated with a substance having a high ultraviolet reflectivity (e.g., stainless steel, aluminum, magnesium oxide, teflon, etc.).

The transmission window 230 serves to protect the substrate 220 and the light source, and may be formed of a transparent insulating material. The transmission window 230 may be formed using various materials, and the material thereof is not limited. For example, the transmission window 230 may be formed of quartz or a high molecular organic material. Here, the wavelength of absorption/transmission of the polymer organic material differs depending on the kind of the monomer, the molding method, and the conditions, and therefore, the wavelength can be selected in consideration of the wavelength emitted from the light source. For example, organic polymers such as poly (methyl methacrylate) (PMMA), polyvinyl alcohol (PVA), polypropylene (PP), and low density Polyethylene (PE) hardly absorb ultraviolet rays, whereas organic polymers such as polyester (polyester) may absorb ultraviolet rays.

In the present embodiment, the substrate 220 and the transmission window 230 are provided in a shape and size corresponding to the light source opening 115 of the piping 100. The substrate 220 and the transmission window 230 are attached to the light source opening 115 of the pipe 100. Here, the substrate 220 may have a rectangular shape extending in one direction, but is not limited thereto and may be provided in a circular shape as the case may be. Also, in the present embodiment, the case where there is one light source opening 115 and the substrate 220 corresponding to the light source opening 115 is provided as one is illustrated, but the number of the light source openings 115 or the number of the substrates 220 is not limited thereto and may be provided as a plurality.

In addition to the light source opening 115, a protrusion and a stepped portion may be formed on the outer tube 110 along the circumference of the light source module 200, and a fastening member 250 for mounting the light source module 200 may be provided on a portion of the protrusion, thereby enabling the light source module 200 to be mounted. The fastening member 250 is not particularly limited as long as the light source module 200 can be mounted on the outer tube 110, and may be composed of a screw hole 251 and a screw 253 in one embodiment of the present invention.

In the present embodiment, a substrate holder 240 may be provided to protect the light emitting element 210 from the fluid flowing inside the piping 100 while supporting the substrate 220, and to serve as a seal member for preventing leakage of the fluid. At this time, the substrate holder 240 may be provided in a form of surrounding the substrate 220 along the circumference of the substrate 220, and may compress a protrusion or a step portion fastened to the outer tube 110. The substrate holder 240 has a closed figure (closed figure) shape so that the inside of the main body of the pipe 100 can be separated from the outside when the light source module 200 is fastened to the main body of the pipe 100. For example, the substrate holder 240 may have an O-ring (O-ring) shape. The substrate holder 240 may be formed using an elastic material, which may be, for example, silicone, but is not limited thereto. For example, natural or synthetic rubber may be used as the elastic material, and other high molecular organic elastic materials may be used. However, the shape and number of the substrate holders 240 are not limited thereto, and may be configured by a plurality of sealing members of similar or other shapes. In an embodiment of the present invention, a sealing member may also be disposed between the transmission window 230 and the substrate 220.

As described above, the fluid sterilizing apparatus according to the embodiment of the present application may be provided with a sealing structure in order to prevent the fluid from leaking through the light source opening 115 of the main body of the pipe 100, thereby further ensuring waterproofing.

Further, in the case where the outer tube 110 is formed of a metal having high thermal conductivity, heat that may be generated in the light source module 200 can be efficiently discharged to the outside through the outer tube 110. In particular, although not shown, in an embodiment of the present invention, a portion of the back surface or the front surface of the substrate 220 may be disposed in direct contact with a portion of the outer tube 110, and in this case, heat dissipation may be efficiently performed. In an embodiment of the present invention, defects such as deterioration of the light source module 200 can be minimized by such a heat dissipation structure.

According to an embodiment of the present invention, since the light source may be coupled in a state of being inserted into the inside of the body, rather than being disposed at the outside of the body of the pipe 100, it is disposed at a position relatively close to the internal fluid (e.g., water). Therefore, heat transfer to the flowing internal fluid occurs at the same time, and heat generated from the light source is easily released. As a result, the reliability of the fluid processing device according to an embodiment of the present invention is improved.

According to an embodiment of the present invention, the position of the light source module 200 providing light to the fluid in the pipe may be changed differently from the above-described embodiment.

Referring to fig. 9 and 10, in the fluid treatment apparatus according to the present embodiment, a light source module 200 is provided at one end portions of the outer tube 110 and the inner tube 120, for example, on the second end portion 111b of the outer tube 110 and the second end portion 121b side of the inner tube 120. The light source module 200 is attached to the second end 111b of the open outer tube 110 to seal the inside of the body. In the present embodiment, the light source module 200 is provided only at the second end 111b, but the present invention is not limited thereto, and the light source module 200 may be provided on the first end 111a side in a similar manner.

In the present embodiment, since the light source module 200 is disposed at the second base 140 side, the inner tube 120 may be disposed in a shape blocking the second end 121 b. That is, the second end 121b of the inner pipe 120 facing the second base 140 may be provided in a blocked shape without being insertedly coupled with the second base 140 and directly contacting the second base 140. However, the shapes of the light source module 200 and the second base 140 are not limited thereto, and may be modified into various forms.

The light source module 200 includes: a substrate 220 arranged perpendicular to the extending direction of the pipe 100 main body; one or more light-emitting elements 210 arranged on the substrate 220 and facing the inside of the pipe 100; a transmission window 230' transmits light from the light emitting element 210. A second base 140 screwed to the second end 111b of the pipe 100 is disposed outside the substrate 220.

In an embodiment of the present invention, power may be applied to the light emitting element 210, and a wiring for applying power is connected to the light source through the substrate 220.

In an embodiment of the invention, the light emitting elements 210 of the light source module 200 can be arranged in various numbers and in various forms. The light emitting element 210 may be provided in plurality and arranged to be able to provide light to both the first inner space 101 and the second inner space 102.

However, the arrangement of the light emitting elements 210 is not limited thereto, and for example, the substrate 200 of the light source module 200 may include a first region a1 corresponding to the first internal space 101 and a second region a2 corresponding to the second internal space 102, the light emitting elements 210 providing light to the first internal space 101 may be arranged at the first region a1, and the light emitting elements 210 providing light to the second internal space 102 may be arranged at the second region a 2. In an embodiment of the present invention, the irradiation area of the light emitting element providing light to the first inner space 101 and the irradiation area of the light emitting element providing light to the second inner space 102 may overlap each other within the pipe 100 (e.g., a portion of the area between the outer tube 110 and the inner tube 120).

In an embodiment of the present invention, the first and second regions a1 and a2 may have substantially the same shape corresponding to the shape of the transverse direction section of the outer tube 110 and the inner tube 120. Accordingly, the diameter of the second region a2 may be set to a value corresponding to the inner diameter of the inner tube 120, the first region a1 may have a circular ring shape surrounding the second region a2, and the outer inner diameter is set to a value corresponding to the diameter of the outer tube.

In the present embodiment, the numbers of the light emitting elements 210 arranged in the first and second regions a1 and a2 may be different from each other, and the wavelength bands and/or the intensities of light emitted from the light emitting elements 210 arranged in the first and second regions a1 and a2 may be the same as or different from each other.

In the case where the light emitting elements 210 are thus arranged differently by regions, there is an advantage in that the fluid passing through the first and second

internal spaces

101 and 102 can be treated simultaneously with the same conditions, and the fluid passing through the first and second

internal spaces

101 and 102 can be treated individually with different conditions according to the regions. For example, the fluid passing through the first interior space 101 may be first treated with light of a particular wavelength, and the fluid passing through the second interior space 102 may be subsequently treated with light of a different wavelength. Here, when the fluids passing through the first internal space 101 and the second internal space 102 are separately treated with different wavelengths, the inner tube 120 may be made of an opaque material to prevent mixing of light of different wavelengths.

The second base 140 may be provided with a lead-out opening 145 connected to a wiring of the light emitting element 210, and the wiring may be led out to the outside through the lead-out opening 145 of the second base 140.

In the present embodiment, the second base 140 may be formed of a metal having high thermal conductivity, and may be in direct contact with at least a portion of the rear surface of the substrate 220. When the second base 140 is made of a metal having high thermal conductivity, heat generated in the light source module 200 can be efficiently discharged to the outside by directly contacting the second base 140 on the rear surface of the substrate 220. The material constituting the second base 140 is not particularly limited to a substance having high thermal conductivity. Further, when the light source module 200 is further provided on the first base 130 side, the first base 130 may be formed of a material having high thermal conductivity (for example, metal).

In the present embodiment, the substrate 220 and the transmission window 230' are mounted to the second end portion 111b of the pipe 100, and are provided in a shape and size corresponding to the cross-section of the second end portion 111b of the pipe 100. Here, the substrate 220 may be provided in a circular shape.

A protrusion and a step portion may be formed on an inner sidewall of the outer tube 110 to mount the light source module 200, and a fastening member for mounting the light source module 200 may be provided at a portion of the protrusion. The fastening member is not particularly limited as long as the light source module 200 can be attached to the outer tube 110.

In the present embodiment, the case where the light source module 200 is mounted to the inner wall of the outer tube 110 is illustrated, but in another embodiment of the present invention, the light source module 200 may be mounted to the second base 140. When the light source module 200 is mounted on the second base 140, the second base 140 may be additionally provided with a protrusion and a step portion, so that the light source module 200 can be mounted.

In the present embodiment, a substrate holder 240' may be provided to protect the light emitting element 210 from the fluid flowing inside the piping 100 while supporting the substrate 220, and to serve as a sealing member for preventing leakage of the fluid.

As described above, the fluid sterilizing apparatus according to the embodiment of the present application may be provided with a sealing structure in order to prevent fluid leakage, thereby further ensuring waterproofing. Further, the fluid treatment apparatus has a heat dissipation structure for efficiently discharging heat generated in the light source module 200, thereby improving the reliability of the fluid treatment apparatus.

In the fluid treatment device according to an embodiment of the present invention, the heat dissipation structure for reducing heat generated at the light source module may also be variously formed.

Referring to fig. 11, the fluid treatment apparatus may include a cooling fan 300 between the light source module 200 and the second base 140. The cooling fan 300 is connected to a power supply to supply air to the rear surface of the substrate 220, thereby cooling heat generated in the light source module 200.

In an embodiment of the present invention, defects such as deterioration of the light source module can be minimized by such a heat dissipation structure, and as a result, a fluid treatment device with higher reliability can be provided.

As described above, the present invention has been described with reference to the schematic drawings, but the present invention is not limited to the embodiments and drawings described in the present specification, and it is obvious to those skilled in the art that various modifications can be made within the technical spirit of the present invention. For example, the above-described embodiments may be variously combined without departing from the concept of the present invention.

Even if the above description of the embodiment of the present invention does not explicitly describe or explain the effect of the application of the configuration according to the present invention, the technical effect predictable from the corresponding configuration should be recognized.
