FIG. 1 is an exploded perspective view showing an overall configuration of a sterilization module 100 according to an embodiment of the present application, and FIG. 2 is a sectional view showing an assembled cross section of the sterilization module 100 of FIG.

1 and 2, the sterilizing module 100 includes a main body 110, a transparent member 140, a sealing member 150, a light source unit 160, and a fastening member 170.

The main body 110 has a structure in which a top surface and a bottom surface are partially opened, and forms an appearance of the sterilizing module 100. The main body 110 also provides a space for installing the transparent member 140, the sealing member 150, the light source unit 160, and the like. The main body 110 includes a lower body 120 and an upper body 130.

The lower body 120 is formed at a lower portion of the main body 110. The lower body 120 may be formed in a cylindrical shape having open top and bottom faces. However, the shape is not limited as long as the sealing member 150 and the light source unit 160 can be mounted. For example, the lower body 120 may be formed in a polygonal shape such as a rectangle. As another example, the outer side of the lower body 120 may have a cylindrical shape, and the inner side of the lower body 120 may have a polygonal shape.

The upper body 130 is formed on the upper part of the main body 110 and covers the lower body. The upper body 130 may be formed to have a circular shape in the lateral direction, that is, in the first and second directions (the cross-section in the X-Y direction). However, this is an example, and the upper body 130 may be formed in a shape such as a polygonal, oval or the like in cross section in the lateral direction.

An ultraviolet ray outlet 131 is formed at the center of the upper body 130. The ultraviolet ray outlet 131 corresponds to a passage through which the ultraviolet ray irradiated from the light source unit 160 is discharged to the outside of the sterilizing module 100. The ultraviolet ray outlet 131 may be formed in a rectangular shape passing through the upper body 130, for example. However, the shape of the ultraviolet ray outlet 131 is not limited as long as it is an example and it is possible to provide a passage for emitting ultraviolet rays to the outside. For example, the ultraviolet ray outlet 131 may be formed in a circular or polygonal shape passing through a part of the upper body 130.

The sterilization module 100 may be mounted to an external device by threaded engagement with an external holder 220 (see FIG. 16). In this case, the outer peripheral surface of the lower body 120 may be formed with a thread for screw connection with the outer holder 220 (see FIG. 16), as shown in FIG. In order to mount the outer holder 220, the diameter of the upper body 130 may be larger than the diameter of the lower body 120. This will be described in more detail with reference to FIG. 17 below.

The transparent member 140 is formed to have a shape corresponding to the ultraviolet ray outlet 131. The transparent member 140 is installed at the ultraviolet ray outlet 131 together with the sealing member 150 and is disposed inside the main body 110 from the outside of the main body 110. [ . For example, as shown in FIG. 1, when the ultraviolet ray outlet 131 is formed in a rectangular shape, the transparent member 140 may be formed in a rectangular shape such as the ultraviolet ray outlet 131. However, the shape of the transparent member 140 is not limited as long as it can be seated on the ultraviolet ray outlet 131 to block the outside and the inside of the main body 110 from each other.

The transparent member 140 is formed using a material that transmits ultraviolet rays so that ultraviolet rays emitted from the light source unit 160 can be irradiated to the outside of the sterilizing module 100. For example, the transparent member 140 may be formed using at least one of quartz, fused silica, polymethyl methacrylate (PMMA) resin, and fluoropolymer resin .

The sealing member 150 accommodates the transparent member 140 therein and provides a waterproof structure between the ultraviolet ray outlet 131 and the transparent member 140. For example, as shown in FIG. 2, a locking groove may be formed in the inner surface of the sealing member 150 to receive the respective ends of the transparent member 140, The transparent member 140 can be housed in the sealing member 150 by being fitted into the fastening groove. Thereafter, the sealing member 150 is provided in the ultraviolet ray outlet 131 together with the transparent member 140, and the substrate 161 presses the sealing member 150, thereby forming a gap between the ultraviolet ray outlet 131 and the transparent member 140 Can be sealed. Accordingly, external water can be prevented from penetrating through the ultraviolet ray outlet 131.

The sealing member 150 may be formed of a flexible material having flexibility or an adhesive material. For example, the sealing member 1150 may be formed of VITON, ETYLENE PROPYLENE, TEFLON, or KALREZ, but is not limited thereto.

The light source unit 160 emits ultraviolet rays having sterilizing function and ultraviolet rays emitted from the light source unit 160 are emitted to the outside of the sterilizing module 100 through the transparent member 140. The light source unit 160 includes a substrate 161, a light source 162, and a light source unit coupling portion 163.

The substrate 161 has a shape corresponding to the lower body 120 and is installed inside the lower body 120. For example, when the lower body 120 is formed into a cylindrical shape, the substrate 161 may have a circular cross-sectional area. Further, in order to draw the electric wire connected to the light source 162 to the outside, a part of the side portion of the substrate 161 may be cut. However, the shape of the substrate 161 is not limited as long as it is an example and it can be installed in the lower body 120 to press the sealing member 150.

The substrate 161 is electrically connected to the light source 162 and supplies a power source supplied from the outside to the light source 162. For example, the substrate 161 may be a circuit board, a printed circuit board (PCB), a metal substrate, or a ceramic substrate. However, the type and material of the substrate 161 are not particularly limited as long as they are illustrative and can be electrically connected to the light source 162.

The light source 162 is mounted on the upper surface of the substrate 161 and emits ultraviolet rays having sterilizing effect. For example, the light source 162 may be a light emitting diode chip that emits ultraviolet light having a wavelength range of 200 nm to 280 nm, which is a UVC region. However, this is merely an example, and if the emitting ultraviolet ray has a sterilizing effect, the kind of the light source 162 and the emission wavelength are not limited.

The light source 162 emits light mainly toward the upper side of the substrate 161. However, the light source 162 may have a variety of directing angles. Depending on the light source 162, some light may be emitted not only in the upper direction, but also in the side direction of the light source 162. Accordingly, in one embodiment of the present invention, at least a portion of the substrate 161 may be provided with additional reflecting members to maximize the upward directed light. The shape or material of the reflecting member is not particularly limited as long as it can reflect light upward. For example, the reflecting member may be provided in the form of a reflecting film on the upper surface of the substrate 161, and an inorganic filler having a small particle diameter may be used as the reflecting member. In one embodiment of the present invention, examples of the inorganic filler include barium sulfate, calcium sulfate, magnesium sulfate, barium carbonate, calcium carbonate, magnesium chloride, aluminum hydroxide, magnesium hydroxide, calcium hydroxide, titanium dioxide, alumina, silica, talc, zeolite But the present invention is not limited thereto.

The light source unit fastening portion 163 is formed through the substrate 161 so that the fastening member 170 fastens the substrate 161 to the main body 110. For example, as shown in FIG. 1, three light source unit fastening portions 163 may be formed on the substrate 161. However, the number of the light source unit engaging portions 163 is not limited as long as the substrate 161 can be stably fixed to the main body 110.

The fastening member 170 passes through the light source unit fastening part 163 and fastens the substrate 161 to the main body 110. For example, the fastening member 170 may be fastened to the main body fastening portion 133 (see FIG. 3) of the main body 110 through the light source unit fastening portion 163. For example, the fastening member 170 may be a screw, and in this case, a screw groove may be formed in an inner wall of the main body fastening portion 133.

1 and 2, the sterilizing module 100 according to the embodiment of the present application emits ultraviolet rays to the outside through the transparent member 140. [ Thus, the sterilization module 100 can perform sterilization operations on the outside.

Particularly, the sterilizing module 100 according to the embodiment of the present application mounts a light source in the form of a chip rather than an LED package on the substrate 161, and the chip is protected from the outside by the transparent member 140 . That is, the sterilizing module 100 according to the embodiment of the present invention can provide the light source 162, the main body 110, and the transparent member 140 as one package. Thus, by providing the light source 162, the main body 110 and the transparent member 140 in one package, the sterilizing module 100 can be miniaturized.

To be more specific, a conventional sterilizing module using LED as a light source includes a main body and a transparent member provided on an upper surface of the main body, and a substrate and a light source mounted on the substrate are disposed below the transparent member. In particular, since the conventional sterilizing module uses an LED package as a light source, an LED package is mounted on the substrate instead of the LED chip. The LED package includes a lens portion for protecting the LED chip, Package structure. For example, LED packages include lamp-type LED packages, surface-mount LED packages, and COB LED packages.

In this case, if the distance in the third direction (z) between the LED package and the transparent member is "a", "a" should be at least longer than the length of the LED package in the third direction (that is, the height of the package). Furthermore, if a connector or the like is mounted on the substrate, the distance " a " between the LED package and the transparent member may become longer.

On the other hand, the sterilizing module 100 according to the embodiment of the present application mounts an LED chip on a substrate 161, rather than an LED package. In this case, if the distance between the LED chip 162 and the transparent member 140 in the third direction z is "b", the height of the LED chip 162 is lower than the height of the LED package, May be shorter than " a ". Accordingly, the sterilizing module 100 according to the embodiment of the present invention has an advantage in miniaturization compared with the conventional one.

3 to 6 are views showing the structure of the main body 110 of FIG. 1 in more detail. 3 and 4 are perspective views showing the shape of the main body 110. FIG 5 is a bottom view showing a lower portion of the main body 110. FIG 6 is a cross- Sectional view.

3 to 6, the main body 110 can be divided into an upper body 130 and a lower body 120. The upper body 120 includes an ultraviolet ray outlet 131, a guide 132, A body fastening portion 133, a seat portion 134, and the like are formed.

The ultraviolet ray outlet 131 is a passage through which the ultraviolet rays are emitted to the outside, and is formed through the upper body 130. The ultraviolet ray outlet side wall 131_1 may be formed to have a predetermined slope so as to minimize the loss of ultraviolet rays emitted to the outside through the ultraviolet ray outlet 131. [

More specifically, when the ultraviolet ray emitted from the light source 162 is irradiated to the outside, some of the ultraviolet rays may be reflected on the outlet side wall 131_1 and may not be irradiated to the outside. In order to prevent unintentional reflection of ultraviolet rays, the ultraviolet ray outlet sidewall 131_1 may be formed so that the diameter of the inscribed circle increases from the upper body lower surface 130_1 to the upper body upper surface 130_2. In this case, the inclination of the ultraviolet ray exit sidewall 131_1 may be set to a range in which the ultraviolet ray is irradiated to the widest possible range, taking into consideration the directivity angle of the light source 162. [

Since the distance between the transparent member 140 installed in the ultraviolet ray outlet 131 and the light source 162 is shorter than the conventional one, the area of the ultraviolet ray outlet 131 can be made smaller than the ultraviolet ray exit of the conventional sterilizing module have.

More specifically, it is assumed that a light source having a certain directivity angle is mounted on the sterilizing module. In this case, in order to emit ultraviolet rays to the outside through the transparent member without ultraviolet ray loss, a transparent member having a larger area should be used as the distance between the light source and the transparent member becomes larger. This means that the ultraviolet ray outlet through which the transparent member is installed must also be widened as the distance between the light source and the transparent member increases. As a result, the miniaturization of the sterilizing module is hindered and the manufacturing cost is increased. The distance between the light source 162 and the transparent member 140 is shorter than that in the prior art because the LED chip is mounted on the substrate 161 instead of the LED package in the sterilizing module 100 according to the embodiment of the present invention. Therefore, the ultraviolet ray outlet 131 on which the transparent member 140 is provided can be formed smaller than the conventional one.

The guide 132 protrudes in the third direction (Z direction) from the upper body bottom surface 130_1. The guide 132 is also formed around the ultraviolet ray outlet 131 and provides a space for accommodating the sealing member 150 together with the seating portion 134. [

The main body fastening part 133 is formed to protrude in the third direction (Z direction) from the upper body bottom surface 130_1. For example, as shown in FIG. 4, three main body fastening portions 133 can be formed. However, if the substrate 161 can be stably fixed, the number of the main body fastening portions 133 is It is not limited.

The one end of the main body coupling part 133 protruding in the third direction may be formed to be longer than the one end protruding in the third direction of the guide 132, for example. One end of the main body coupling part 133 is in close contact with the upper surface of the substrate 161 and one end of the guide 132 is in close contact with the upper surface of the substrate 161 .

In another example, one end of the main body coupling portion 133 protruding in the third direction may be formed so as to be located on the same line as one end of the guide 132 protruding in the third direction. When the substrate 161 is fixed to the main body 110, one end of the main body fastening part 133 and one end of the guide 132 can be brought into close contact with the upper surface of the substrate 161.

In this case, the length of the main body fastening portion 133 in the third direction and / or the length of the guide 132 in the third direction may be formed in consideration of the height of the sealing member 150 and the light source 162 have. For example, the length of the main body fastening portion 133 in the third direction may be shorter than the height of the sealing member 150 so that the main body fastening portion 133 can be waterproofed by the elastic compression of the sealing member 150. The length of the main body fastening portion 133 in the third direction is set to be shorter than the distance between the transparent member 140 and the substrate 161 in order to protect the light source 162 mounted on the substrate 161. [ 162, respectively. This will be described in more detail below with reference to FIG. 15 and FIG.

The seat portion 134 is formed on the upper body bottom 130_1 and is formed along the circumference of the ultraviolet ray outlet 131. [ 5, the seating portion 134 indicates a portion between the guide 132 and the ultraviolet ray outlet 131, which is formed along the periphery of the ultraviolet ray outlet 131 in the upper body bottom surface 130_1.

The seating portion 134 has a shape corresponding to the sealing member 150. For example, the shape and width of the seating portion 134 in the lateral direction (i.e., the first and second directions) may be the same or similar to the shape and width of the sealing member 150 in the lateral direction. Accordingly, the sealing member 150 is not directly exposed to the outside, so that the beauty of the sterilizing module 100 can be avoided.

5, first to third supporting members 133_1 to 133_3 may be formed on the inner surfaces of the upper body bottom 130_1 and the lower body 120. As shown in FIG. The first to third supporting members 133_1 to 133_3 are formed by dispersing the pressure applied to the lower body 120 in the upper body 130 when the outer holder 220 is coupled to the lower body 130, And more stable support of the.

Meanwhile, the main body 110 may be formed of a waterproof material or the outer wall of the main body 110 may be coated with a waterproof material. Here, the outer wall of the main body 110 is a surface exposed to the outside of the main body 110. For example, the outer wall of the main body 110 may be an outer surface of the lower body 120, an upper body upper surface 130_2, and an upper body lower surface 130_1. Since the outer wall of the main body 110 is coated with a waterproof material, it is possible to prevent the main body 110 from being corroded by the object. In addition, it is possible to prevent the sterilizing module 100 from being shortened in life due to corrosion by water.

FIGS. 7 and 8 are views showing the transparent member 140 and the sealing member 150 of FIG. 1 in more detail. 7 is a perspective view showing the combination of the transparent member 140 and the sealing member 150 and FIG. 8 is a sectional view showing the combination of the transparent member 140 and the sealing member 150. FIG.

7 and 8, a locking groove 151 is formed on the inner side of the sealing member 150, and each end of the transparent member 140 is fitted into the locking groove 151 of the sealing member 150 . The first to third protrusions 152_1 to 152_3 are formed along the periphery of the sealing member 150 on the upper surface, the side surface, and the lower surface of the sealing member 150, respectively, to provide a more complete waterproof structure.

More specifically, when the fastening member 170 is fastened to the main body fastening portion 133 through the light source unit fastening portion 163 of the substrate 161, the substrate 161 presses the sealing member 150 do. In this case, the upper surface of the sealing member 150 is pressed against the seating portion 134, the side surface of the sealing member 150 is pressed against the guide 132, and the lower surface of the sealing member 150 is pressed against the substrate 161. [ Respectively.

At this time, if the pressure applied to the sealing member 150 by the substrate 161 is too large, the transparent member 140 may be damaged. Accordingly, the pressure applied to the sealing member 150 by the substrate 161 should not exceed a predetermined reference pressure. In this case, the pressure applied to the sealing member 150 by the substrate 161 is too small to be waterproof There is a risk that it will not.

In order to prevent such a risk, the sealing member 150 may further include first to third protrusions 152_1 to 152_3. Since the first to third protrusions 152_1 to 152_3 are formed in a narrow width and can be easily elastically deformed, they can be easily compressed and adhered even with a small pressure. Therefore, the waterproof ability can be improved without affecting the transparent member 140.

On the other hand, the surface of the transparent member 140 may be water repellent coated. When water repellent coating is applied to the surface of the transparent member 140, water droplets that fall on the transparent member 140 do not spread but can easily fall off from the surface of the transparent member 140. Therefore, it is possible to prevent the amount of ultraviolet light emitted to the outside from decreasing due to the water droplets that have fallen on the transparent member 140.

The surface of the sealing member 150 or the inner wall of the sealing member 150 may be coated with a substance having a high reflectance (for example, stainless steel, aluminum, magnesium oxide, Teflon, etc.). In this case, the sealing member 150 may reflect the ultraviolet rays striking the inner wall of the sealing member 150 and face the ultraviolet ray outlet 131. Therefore, it is possible to prevent the ultraviolet rays from being hit by the inner wall of the sealing member 150 to be lost, thereby increasing the sterilizing efficiency of the sterilizing module 100.

9 to 11 are views for explaining the light source unit 160 in more detail. 9 is a view showing a state in which the light source 162 is mounted on the substrate 161 in more detail, and FIGS. 10 and 11 are sectional views showing the structure of the light source 162. FIG.

9, the light source unit 160 includes a substrate 161, a light source 162, a light source unit coupling portion 163, a support groove 164, and a connection passage 165.

A light source 162 is mounted on the upper surface of the substrate 161. A connection passage 165 is formed at one side of the substrate 161 to extend a wire (not shown) for supplying power to the light source 162. A substrate 161 is connected to the other side of the substrate 161, A support groove 164 for passing the third support member 133_3 (see Fig. 5) is formed in fixing to the body 110. Fig.

The substrate 161 may be, for example, a heat dissipation substrate, but is not limited thereto. As another example, the substrate 161 may be a printed circuit board.

The light source 162 is mounted on the upper surface of the substrate 161 and emits ultraviolet rays having sterilizing effect. 9, one light source 162 is mounted on the upper surface of the substrate 161 by way of example, but the number of the light sources 162 is not limited thereto. For example, a plurality of light sources may be mounted on the upper surface of the substrate 162.

The light source unit coupling portion 163 is formed through the substrate 161 so that the light source unit coupling portion 163 is fixed to the main body 110 by the coupling member 170.

In one embodiment of the present application, the light source 162 may be mounted on the substrate 161 in various manners. For example, the light source 162 may be an LED, and the LED may be formed by growing a conductive semiconductor layer, an active layer, or the like on an epitaxial substrate. In addition, when the LED is mounted on the substrate 161, the ultraviolet rays may be emitted through the growth substrate by making the growth substrate (epitaxial) away from the substrate 161 to face the transparent member 140. In this case, since the directivity angle of ultraviolet rays passing through the growth substrate is larger than the directivity angle of ultraviolet rays that have not passed through the growth substrate, a wider range can be effectively sterilized.

FIG. 10 shows a cross-section of a light source 162 according to an embodiment of the present application, and FIG. 11 shows a cross-sectional view taken along the perforated line A-B-B'-A 'of FIG. 10 and 11, a light source 162 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 second conductivity type semiconductor layer 1113 may be disposed on the first conductivity type semiconductor layer 1111 and the active layer 1112 may include a first conductivity type semiconductor layer 1111 and a second conductivity type semiconductor layer 1113, As shown in FIG. 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), and the second conductivity type semiconductor layer 1113 may include a p-type impurity (for example, Mg) have. 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 162, electrons and holes are combined 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 light source 162 may include at least one mesa M including an active layer 1112 and a second conductivity type semiconductor layer 1113. [ The mesa M may include a plurality of protrusions, and the plurality of protrusions may be spaced from each other. The present invention is not limited thereto, and the light source 162 may include a plurality of mesas M spaced from each other. The side surface of the mesa M may be inclined by using a technique such as photoresist reflow and the side surface of the inclined mesa M may improve the luminous efficiency generated in the active layer 112. [

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 162, 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 162. [ 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 bonding strength between the first insulating layer 1130 and the second electrode 1120 is improved so that the reliability of the light source 162 is improved as compared with the case where the first insulating layer 1130 and the second electrode 1120 are in contact with each other. 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 162 may be mounted on the substrate 161 directly or through a pad.

For example, when the light source 162 is mounted on the substrate 161 through a pad, two pads disposed between the light source 162 and the substrate 161 may be provided, The first electrode 1140 and the second electrode 1120 can be in contact with each other. 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.

As another example, when the light source 162 is directly mounted on the substrate 161, the first electrode 1140 and the second electrode 1120 of the light source 162 can be directly bonded to the wiring on the substrate 161. 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). However, this is merely an example, and the bonding material may include various materials having conductivity.

12 to 16 are views showing a sterilization module 100 of FIG. 1 assembled. 12 and 13 are perspective views showing a sterilization module 100 of FIG. 1 assembled, and FIG. 14 is a bottom view showing an assembled state of the sterilization module 100 of FIG. 1. Referring to FIG. FIG. 15 is a sectional view taken along a perforated line C-C 'of FIG. 14, and FIG. 16 is a partially enlarged view of a portion D of FIG.

12 to 14, the transparent member 140 is exposed to the outside through the ultraviolet ray escape opening 131 on the upper surface of the upper body 130. The fastening member 170 is fastened to the lower body 120 through the light source unit fastening portion 163 formed on the substrate 161 and firmly fixes the substrate 161 to the lower body 120. At this time, the first and second support members 133_1 and 133_2 formed on the upper body bottom surface 130_1 are exposed to the outside through the connection passage 165, and the third support member 133_3 is exposed to the support groove 164 To the outside.

Referring to FIGS. 15 and 16, the fastening member 170 passes through the substrate 161 and is fastened to the main body fastening part 133. At this time, the upper surface of the substrate 161 is in close contact with the sealing member 150, and the fastening member 170 presses the substrate 161 in the third direction (Z direction) . As the substrate 161 presses the sealing member 150, the sealing member 150 is elastically compressed between the seating portion 134 and the substrate 161. In this case, for example, the length d2 in the third direction of the sealing member 150 elastically compressed by the pressing of the substrate 161 is equal to the length d2 in the third direction of the main body fastening portion 133 ).

The sealing member 150 prevents external water from penetrating into the sterilizing module 100 and prevents the transparent member 140 and the substrate 161 from being damaged so that the light source 162 mounted on the substrate 161 is not damaged. Thereby forming a predetermined spacing distance therebetween.

Specifically, by the elastic compression of the sealing member 150, between the sealing member 150 and the seating portion 134, and / or between the sealing member 150 and the guide 132, and / or between the sealing member 150 and the sealing member 150, And the substrate 161 is prevented from being infiltrated.

A predetermined distance d1 may be formed between the transparent member 140 and the substrate 161 by the sealing member 150 fitted to both ends of the transparent member 140. [ In other words, the sealing member 150 may serve as a spacer that physically separates the transparent member 140 and the substrate 161 so that the light source 162 is not damaged.

The distance d1 between the transparent member 140 and the substrate is longer than the height of the light source 162 so as to protect the light source 162 and at the same time, The distance between the light source 140 and the light source 162 can be minimized. For example, the distance d1 between the transparent member 140 and the substrate 161 may be set to be not less than about 200 mu m and not more than about 2 mm. The minimum distance d1 between the transparent member 140 and the substrate 161 takes into account the height of the light source 162 on the substrate 161. The distance d1 between the transparent member 140 and the substrate 161 is To avoid the case where the light source 162 is directly contacted by the transparent member 140 or pressed by the transparent member 140 in the case of less than about 200 mu m. However, the minimum distance d1 between the transparent member 140 and the substrate 161 may be set differently depending on the height of the light source 162, or may have a smaller value. The maximum distance d1 between the transparent member 140 and the substrate 161 takes into account the sterilizing power by ultraviolet rays. When the distance d1 between the transparent member 140 and the substrate 161 exceeds about 2 mm, the sufficient sterilizing effect due to ultraviolet rays It is hard to see. Accordingly, in the embodiment of the present invention, by setting the distance d1 between the transparent member 140 and the substrate 161 to about 2 mm or less, the sterilizing force against the external fluid can be sufficiently maintained.

In the case of a general sterilization module, an LED package is mounted on a substrate, and an LED chip is embedded in the LED package. Therefore, the distance between the LED chip and the transparent member must be at least longer than the height of the LED package, which causes a decrease in sterilizing power as the distance increases. The distance d1 between the light source 162 and the transparent member 140 is smaller than the distance d1 between the light source 162 and the transparent member 140. In the sterilizing module 100 according to the embodiment of the present invention, As shown in FIG. The distance d1 between the light source 162 and the transparent member 140 can be minimized because the sealing member 150 is used to separate the transparent member 140 and the substrate 161 without a separate spacer have. Accordingly, the sterilization module 100 according to the embodiment of the present application can maximize sterilizing power.

Also, since the sterilizing module 100 according to the embodiment of the present invention has only one air layer between the transparent member 140 and the light source 162, there is an advantage that the heat radiation performance is improved.

More specifically, in the case of a general sterilization module in which an LED package is mounted on a substrate, a double air layer is formed between the LED chip and the transparent member. For example, in the case of a general sterilization module, a first air layer is formed inside the LED package, and a second air layer is formed between the LED package and the transparent member. In this case, even if the transparent member comes into contact with the cool fluid outside, the temperature of the fluid may be difficult to be transmitted to the first air layer by the heat insulating function of the second air layer. Accordingly, the cooling efficiency of the LED chip due to the fluid is reduced, thereby deteriorating the LED chip, and the lifetime of the chip can be shortened. On the other hand, since the LED chip is mounted on the substrate 161, only one air layer is formed between the light source 162 and the transparent member 140 according to an embodiment of the present invention. Since the temperature of the air layer in which the light source 162 is exposed is lowered when the transparent member 140 contacts the external cool fluid, the sterilization module 100 according to the embodiment of the present application is improved in heat radiation performance There is an advantage that deterioration of the chip can be prevented. Moreover, the sterilizing module 100 of the present application can further improve the heat dissipation function as compared with the general sterilizing module since the LED chip is in direct contact with the substrate 161 having the heat-dissipating function.

On the other hand, the distance d1 between the transparent member 140 and the substrate 161 will be formed in proportion to the thickness of the sealing member 150. [ The thickness of the sealing member 150 is larger than the thickness of the light source 162 to protect the light source 162 and the distance between the transparent member 140 and the light source 162 to maximize the sterilizing power, Can be minimized. However, this is an exemplary one, and the thickness of the sealing member 150 may be variously adjusted to the extent that waterproofing is possible.

15 and 16, the length d3 of the guide 132 in the third direction is shorter than the length d2 of the main body fastening portion 133 in the third direction. However, this is an exemplary one, and the technical idea of the present application is not limited thereto. For example, the length d3 of the guide 132 in the third direction may be the same as the length d2 of the main body coupling portion 133 in the third direction. In this case, the substrate 161 can be firmly fixed to one end of the guide 132 and can be more firmly fixed, and the waterproof function can be further improved by the adhesion between the substrate 161 and the guide 132.

17 to 19 are views for explaining how the sterilization module 100 of FIG. 1 is installed in the external device 10 by being fastened to the external holder 220. FIG. 17 is an exploded perspective view showing a state in which the outer holder 220 is fastened to the sterilizing module 100 of FIG. 1 and FIG. 18 is an exploded perspective view showing the outer holder 220 fastened to the sterilizing module 100. FIG. Sectional view. 19 is a cross-sectional view showing a state in which the sterilizing module 100 is installed in the external device 10 using the external holder 220. FIG.

Referring to FIGS. 17 and 18, the outer holder 220 is formed in a shape corresponding to the lower body 120. For example, as shown in FIGS. 17 and 18, the outer holder 220 is formed into a cylindrical shape having open top and bottom surfaces, and a thread is formed on the inner circumferential surface. The outer holder 220 is rotated in accordance with the thread of the lower body 120 so that the lower body 120 is fastened to the lower body 120. [ .

An external sealing member 210 may additionally be disposed between the main body 110 and the external holder 220 to provide an additional watertight structure between the main body 110 and the external holder 220.

The outer sealing member 210 may have a shape corresponding to the upper body 130. For example, the outer sealing member 210 may be formed in the shape of an O-ring as shown in FIG. 17, but a waterproof structure may be formed between the main body 110 and the outer holder 220 If it can be provided, its shape is not limited.

On the other hand, first, second, and third protrusions for improving the waterproof performance may be additionally formed on the top, bottom, and side surfaces of the outer sealing member 210, similar to the sealing member 150 of FIG.

Referring to Fig. 19, a sterilization module 100 according to an embodiment of the present application is installed in the external device 10. Fig. The external device 10 may be, for example, a water storage tank for storing water, and the sterilization module 10 may be installed in the water storage tank to sterilize the water stored in the water storage tank.

First, the upper body 130 of the sterilizing module 100 is inserted into the external device 10 from outside.

Then, the outer holder 220 is coupled to the outer wall of the lower body 120 from the outside of the outer apparatus 10. For example, threads are formed on the outer circumferential surface of the lower body 120, corresponding threads are formed on the inner circumferential surface of the outer holder 220, and the outer holder 220 rotates in accordance with the threads of the lower body 120 So that the outer holder 220 can be coupled to the lower body 120.

In this case, the outer holder 220 presses the outer wall of the outer device 10 while the outer holder 220 is coupled to the lower body 120, and the lower surface of the upper body 130 and the outer sealing member 210 Thereby pressing the inner wall of the external device 10. Thus, the sterilizing module 100 is fixed to the external device 10. [ At this time, an external sealing member 210 may be additionally disposed between the upper body 130 and the inner surface of the external device 10, so that water stored in the external device 10 is discharged to the outside of the external device 10 Can be further prevented.

On the other hand, as shown in FIG. 19, when the sterilizing module is installed on the lower surface of the external device 10, the transparent member may be damaged by the water pressure in the general sterilizing module. However, as described above, the sterilizing module 100 according to the embodiment of the present application can be mounted with a transparent member having a size larger than that of the conventional sterilizing module. Therefore, the sterilization module 100 according to the present application is less likely to be damaged by water pressure, and can be installed in an external device 10 that stores a large amount of water.

The above description is illustrative, and the technical idea of the present application is not limited thereto. For example, in FIG. 18, it has been described that the outer sealing member 210 is disposed between the upper body 130 and the inner wall of the external device 10. The external sealing member 210 may be disposed between the lower body 120 and the outer wall of the external device 10. [

In Fig. 19, it has been described that the sterilizing module 100 is installed on the lower surface of the external device 10. However, the sterilization module 100 is not limited to being installed on the lower surface of the external device 10. For example, the sterilization module 100 may be installed on the upper surface or the side surface of the external device 10. [ If the sterilizing module 100 is installed on the upper surface of the external device 10, the sterilizing module 100 can emit ultraviolet rays to the surface of the water stored in the external device 10. [ If the sterilization module 100 is installed on the side of the external device 10, the sterilization module 100 can emit ultraviolet light to the surface of the water stored in the external device 10 and / or the interior of the water.

1 to 19, the sterilizing module 100 according to the embodiment of the present application includes a sealing member 150 that receives the transparent member 140 through a coupling groove formed therein, The sealing member 150 not only provides a waterproof function between the ultraviolet ray outlet 131 and the transparent member 140 but also prevents the light source 162 from being crushed and damaged between the substrate 161 and the transparent member 140 Additional spacer function is provided.

Thus, by providing the waterproof function and the spacer function by using the sealing member 150 without the separate spacer, the sterilization module 100 according to the embodiment of the present application is advantageous in downsizing and cost reduction. In addition, as the distance between the transparent member 140 and the light source 162 becomes closer, the path through which the force for pressing the substrate 161 reaches the transparent member 140 can be shortened. Therefore, the waterproof efficiency can be increased

In addition, the sterilizing module 100 according to the embodiment of the present invention does not have a separate quartz-type protection tube formed by wrapping the light source 162 to protect the light source 162. That is, the sterilizing module 100 according to the embodiment of the present invention includes only the transparent member 140 installed at the ultraviolet ray outlet 131, and the transparent member 140 not only blocks the sterilizing module 100 from the outside, And also protects the light source 162. Therefore, the sterilizing module 100 according to the embodiment of the present application is advantageous in miniaturization.

Meanwhile, the sterilization module 100 according to the embodiment of the present application can be provided to the user in the form of an assembled package, and the user can combine the assembled sterilization module 100 with the outer holder 220, (100) can be easily installed in the external device (10). However, this is merely an example, and the sterilization module 100 may be provided to the user in an unassembled state.

It is to be understood, however, that the foregoing description is exemplary and that the technical spirit of the present application may be variously modified or applied. In the following, various modifications or applications according to the technical idea of the present application will be described.

20 and 21 are views showing a main body 110 'according to an embodiment of the present application. 20 is a perspective view of the main body 110 'according to an embodiment of the present application. FIG. 21 is a sectional view of the sterilizing module 100' having the main body 110 ' Fig.

Accordingly, the same or similar elements will be denoted by the same or similar reference numerals, and the same or overlapping descriptions will be omitted below for the sake of brevity.

20 and 21, a sterilizing module 100 'according to an embodiment of the present application includes a main body 110', and the main body 110 'includes a lower body 120' (130 ').

Unlike the main body 110 of the sterilization module 100 of FIG. 1, the main body 110 'of the sterilization module 100' of FIG. 20 includes external holders 220, 17).

That is, the outer surface of the lower body 120 'of the main body 110' of FIG. 20 is not provided with threads for coupling with the outer holder 220. A coupling hole 139 for receiving the external coupling member 230 is formed in the upper body 130 'of the main body 110' of FIG. For example, the outer fastening member 230 may be a screw, and a screw groove may be formed on the inner peripheral surface of the upper body 130 '.

In this case, as shown in Fig. 21, the upper body 130 'of the sterilizing module 100' is inserted into the external device 10 through the outside. Thereafter, the outer coupling member 230 is coupled to the coupling hole 139 of the upper body 130 'in a threaded manner, so that the sterilizing module 100' can be installed in the external device 10.

In this case, a sealing member such as an O-ring may be additionally disposed between the upper body 130 'and the inner wall of the external device 10, so that water stored in the external device 10 leaks out of the external device 10 Can be prevented.

Figures 22 and 23 are views showing sealing members according to one embodiment of the present application. 22 is a cross-sectional view showing the first and second sealing members 150_1 and 150_2 according to one embodiment of the present application. FIG. 23 is a cross-sectional view showing the bonding member 150_3 according to the embodiment of the present application, (150_4).

The sterilization module 100 'of Figures 22 and 23 is similar to the sterilization module 100 described in Figures 1-19. Accordingly, the same or similar elements will be denoted by the same or similar reference numerals, and the same or overlapping descriptions will be omitted below for the sake of brevity.

Referring to FIG. 22, unlike the sealing member 150 shown in FIG. 8, the sealing member of FIG. 22 can be divided into a first sealing member 150_1 and a second sealing member 150_2. That is, if the sealing member 150 shown in FIG. 7 is integrally formed so as to fit the transparent member 140 into the inner connecting groove, the sealing member of FIG. 22 may be formed as an independent first sealing member 150 - And can be mounted on the transparent member 140 using the member 150_2.

More specifically, the first sealing member 150_1 is disposed between the seating portion 134 (see Figs. 4 and 5) and the transparent member 140, and allows water to penetrate through the ultraviolet outlet 131 And a waterproofing member for preventing the water from entering. The second sealing member 150_2 is disposed between the substrate 161 (see FIG. 1) and the transparent member 140 and serves as a spacer for forming a predetermined separation distance between the substrate 161 and the transparent member 140 .

On the other hand, protrusions as shown in FIG. 8 may be formed on the upper and lower surfaces of the first and second sealing members 150_1 and 150_2. In this case, the waterproof performance may be further improved.

23, in place of the first sealing member 150_1, an adhesive member 150_3 may be disposed between the transparent member 140 and the seating portion 134, unlike FIG. In this case, the adhesive member 150_3 can securely fix the transparent member 140 to the mounting portion 134 without detaching it.

The adhesive member 150_3 may be formed using a material having an adhesive force. Further, the adhesive member 150_3 may be formed using a material having a waterproof function.
