Accordingly, the present invention may be embodied in other forms without being limited to the embodiments described below. And in the drawings, the width, length, thickness, etc. of components may be exaggerated for convenience. Like reference numbers indicate like elements throughout the specification, and like reference numbers indicate corresponding like elements.

1 and 2 are exemplary views showing a sterilization module according to a first embodiment of the present invention.

1 is a perspective view showing a sterilization module 100 according to a first embodiment of the present invention. 2 is a cross-sectional view of the sterilization module 100 according to the first embodiment of the present invention.

Referring to FIGS. 1 and 2 , the sterilization module 100 according to the first embodiment may include a collecting unit 120 and a light source unit 110 .

The collecting unit 120 may collect contaminants included in the fluid.

A fluid can be a gas or a liquid. For example, the gas may be air and the liquid may be water. However, the type of fluid is not limited to air and water. The fluid can be any kind of gas or liquid that requires purification.

Contamination sources may be substances that have a harmful effect on the human body, such as pathogenic microorganisms and dust. For example, microorganisms that have a harmful effect on the human body may be bacteria, viruses, fungi, and the like. Alternatively, the fluid may be a droplet containing a contaminant.

The collecting unit 120 may have a plurality of through holes 125 formed therein. The fluid may pass through the collecting unit 120 through the through hole 125 . The collecting unit 120 may collect contaminants included in the fluid when the fluid passes through the through hole 125 .

Accordingly, the through hole 125 formed in the collecting unit 120 may have a size sufficient to separate the contaminants included in the fluid from the fluid. That is, the through hole 125 may be formed to have a smaller size than the contamination source included in the fluid. According to this embodiment, each through hole 125 may be formed to have a diameter of about 30 nm to 10 μm. For example, when the collecting target is bacteria, the diameter of the through hole 125 of the collecting unit 120 may be about 1 μm to about 5 μm. In addition, when the collection target is a virus, the diameter of the through hole 125 of the collection unit 120 may be about 30 nm to 300 nm. In addition, when the fluid is a gas and the collecting target is droplets, the diameter of the through hole 125 of the collecting unit 120 may be about 5 μm to about 10 μm. The size of the through hole 125 is not limited thereto. The size of the through hole 125 may be variously changed according to the type of pollutant to be collected.

The light source unit 110 may include a substrate 111 and at least one light source 112 disposed on the substrate 111 .

A wire may be formed on the substrate 111 , and the wire formed on the substrate 111 may be electrically connected to the light source 112 .

The light source 112 may emit light by receiving power through the substrate 111 . The light source 112 may be light in a wavelength band capable of sterilizing a fluid by inactivating or killing a contaminant. Here, sterilizing the fluid means sterilizing a contaminant included in the fluid, and the sterilization of the fluid and the sterilization of the contaminant may be understood as the same meaning. For example, the light source 112 may emit light having a peak wavelength in a wavelength range of about 250 nm to about 420 nm. In addition, light emitted from the light source 112 may have a full width at half maximum (FWHM) of 30 nm or less. Furthermore, the half width of light emitted from the light source 112 may be 20 nm or less.

According to this embodiment, the light beam angle of the light source 112 may be 140 degrees or less. Furthermore, the light directing angle of the light source 112 may be greater than or equal to 70 degrees and less than or equal to 120 degrees.

A peak wavelength of light emitted from the light source 112, a half-maximum width of light, or a beam angle of light may vary depending on the type of contamination source.

For example, the light source 112 may be a light emitting diode or a chip or package containing a light emitting diode.

The light source unit 110 may include one light source 112 or may include a plurality of light sources 112 . When the light source unit 110 includes a plurality of light sources 112, the plurality of light sources 112 may emit light of the same wavelength range. Alternatively, when the light source unit 110 includes a plurality of light sources 112, at least one light source 112 among the plurality of light sources 112 may emit light having a peak wavelength different from that of the other light sources 112. . In addition, when the light source unit 110 includes a plurality of light sources 112, at least one light source 112 among the plurality of light sources 112 may emit light having a different half width from that of the other light sources 112. . Alternatively, when the light source unit 110 includes a plurality of light sources 112, at least one light source 112 among the plurality of light sources 112 may have a different angle of view from other light sources 112.

For example, the light source unit 110 may include a plurality of light sources 112 to emit light having an appropriate peak wavelength, full width at half maximum, or beam angle according to the type of contamination source. That is, the light source unit 110 includes a light source for emitting light with a peak wavelength, half-width or beam angle suitable for killing bacteria, a light source for emitting light with a peak wavelength, half-maximum width or beam angle suitable for killing viruses, and a light source for killing fungi. A light source that emits light having a peak wavelength, a full width at half maximum, or a beam angle may be included. Accordingly, the light source unit 110 may improve the sterilization efficiency of the fluid by emitting light having a peak wavelength, half-maximum width, or beam angle suitable for sterilization of the corresponding pollutant according to the type of pollutant to be sterilized.

The light source unit 110 may be disposed to emit light to the collecting surface of the collecting unit 120 . For example, the collecting surface may be one surface of the collecting part 120 facing the direction in which the fluid flows. That is, the collecting surface is one surface located in the direction in which the fluid flows into the through hole 125 of the collecting unit 120. In addition, the collecting surface is one surface of the collecting unit 120 facing the light source unit 110 .

Referring to FIGS. 1 and 2 , the collecting unit 120 may include a plurality of collecting units 121 sequentially connected. The plurality of collecting units 121 may be formed to be inclined in a different direction from neighboring collecting units 121 . For example, the plurality of collecting units 121 may be formed to be inclined in the opposite direction to the neighboring collecting units 121 . Accordingly, the collecting unit 120 may have a plurality of bent structures as shown in FIG. 1 . The plurality of collecting units 121 may be areas in which the collecting unit 120 is divided into a plurality of parts.

The light source 112 may be disposed in each of the two collecting units 121 adjacent to each other. At this time, the two collection units 121 adjacent to each other may form a sterilization space, which is a convex space in the opposite direction of the light source 112 . That is, the sterilization space may be a space in which the light source 112 emitted from the light source 112 is irradiated while being surrounded by the collecting surfaces of the collecting units 121 adjacent to each other.

Referring to FIG. 2 , neighboring collection units 121 surrounding the sterilization space may include a first end 131 , a second end 132 , and a third end 133 . For example, the sterilization space may be a space formed by connecting the first end 131 , the second end 132 , and the third end 133 . The first end 131 is one end of one collecting unit 121, the second end 132 is one end of the other collecting unit 121, and the third end 133 is one collecting unit 121 connected to each other. It is the other end of and the other end of the other collection unit 121.

The first end 131, the second end 132, and the third end 133 may be located on different horizontal lines according to angles formed by the collecting units 121 adjacent to each other. That is, the first end 131 and the second end 132 may have the same or different distances from the substrate 111 depending on the angle formed by the collecting units 121 connected to the respective ends. In addition, a distance between the third end 133 and the substrate 111 may be changed according to an angle formed by the collecting units 121 connected to the third end 133 . In the case of the third end 133, the height may vary according to the positions of the first end 131 and the second end 132.

As long as the length or area of each collecting unit 121 of this embodiment is not changed, the size of the sterilization space is not changed even if the position of the first end part 131 to the third end part 133 is changed.

In this embodiment, contaminants are collected when the fluid passes through the through hole 125 of the collecting unit 120 . Therefore, most of the pollutants collected by the collecting unit 120 may be collected on the collecting surface of the collecting unit 120 facing the light source 112 . Contaminants may be exposed to the light of the light source unit 110 while being collected by the collecting unit 120 . At this time, since the collecting surface on which most of the pollutants are collected faces the light source 112, the pollutant on the collecting surface may be continuously exposed to light while the light source 112 emits light. Therefore, the sterilization module 100 of the present embodiment can have better sterilization efficiency than the conventional sterilization module that directly sterilizes fluid without the collecting unit 120 .

In addition, the sterilization module 100 according to this embodiment has a structure in which the collecting unit 120 does not have a generally flat structure but includes a plurality of inclined surfaces. Therefore, in the sterilization module 100 of the present embodiment, the area of the collecting unit 120 disposed in the same size area may be larger than that of the conventional flat collecting unit 120 . That is, the sterilization module 100 of this embodiment may increase the area of the collecting unit 120 disposed in an arbitrary predetermined area. Therefore, the sterilization module 100 of this embodiment can improve the collection efficiency of pollutants.

In addition, in the sterilization module 100 according to the present embodiment, the light source unit 110 is disposed to emit light toward the collecting surface of the collecting unit 120 . That is, the light source unit 110 and the collecting unit 120 are sequentially disposed along the direction in which the fluid flows. Accordingly, the light source unit 110 may directly irradiate light toward the fluid before passing through the collecting unit 120 as well as radiating light to the collecting surface where the contaminants are collected. Therefore, the sterilization module 100 according to the present embodiment simultaneously sterilizes the contaminants included in the fluid and the contaminants collected in the collecting unit 120, so that the sterilization efficiency of the fluid can be improved.

As the maximum width of the sterilization space of the collecting unit 120 decreases, the area of the collecting surface disposed in an arbitrary predetermined area increases. Here, the maximum width of the sterilization space is the distance between ends of the collecting units 121 adjacent to each other. That is, it is the distance between the first end 131 and the second end 132 of the neighboring collection units 121 surrounding the sterilization space. As the area of the collecting surface disposed in the predetermined area increases, the number of through holes 125 of the collecting unit 120 located in the predetermined area also increases. That is, the total area of the through hole 125 of the collecting unit 120 disposed in the predetermined area is increased. When the area through which the fluid can pass is increased in a predetermined region, the velocity of the fluid may increase. When the speed of the fluid increases, the time during which the fluid is exposed to the light of the light source unit 110 decreases.

In addition, as the maximum width of the sterilization space of the collecting unit 120 decreases, the distance between the light source 112 and the other end of the collecting unit 121 increases. Here, the other end of the collection unit 121 is the third end 133 . In addition, as the maximum width of the sterilization space decreases, the difference between the distance from the substrate 111 to one end of the collecting unit 121 and the other end increases. In this case, the light intensity difference between one end and the other end of the collecting unit 121 also increases, and thus the uniformity of the light irradiated to the collecting unit 121 decreases.

In addition, as the maximum width of the sterilization space of the collecting unit 120 increases, the total area of the through hole 125 of the collecting unit 120 disposed in a predetermined area decreases. In this case, since the area where the fluid passes through the collecting unit 120 is reduced, the flow of the fluid may not be smooth. If the flow of the fluid is not smooth, the amount of fluid to be sterilized per hour is reduced.

In addition, when the maximum width of the sterilization space of the collecting unit 120 increases, one end of the collecting unit 121 may be positioned out of the light irradiation area of the light source 112 . That is, light may not be irradiated to a part of the collecting unit 121 . Accordingly, uniformity of light irradiated to the collecting unit 121 may decrease. Furthermore, a portion of the fluid may pass through the collecting unit 120 without being exposed to light from the light source 112 .

As such, when the maximum width of the sterilization space of the collecting unit 120 is too small or too large, the sterilization efficiency may decrease.

In the sterilization module 100 of this embodiment, one ends of the collection units 121 adjacent to each other may be located inside the light beam angle of the light source 112 . That is, the maximum width of the sterilization space formed by the collection units 121 adjacent to each other may be equal to or smaller than the width of the beam beam angle on the same line. Here, the light directing angle is the light directing angle of the light source 112 radiating light to the sterilization space formed by the collecting units 121 adjacent to each other. Therefore, when the light beam angle of the light source 112 increases, the maximum width of the sterilization area may also increase. Accordingly, the angle formed by the collection units 121 adjacent to each other or the distance between ends may also increase.

Furthermore, the third end 133 of the sterilization space may be located on the same vertical line as the central axis of the light exit surface of the light source 112 . In addition, the third end 133 of the sterilization space may be positioned adjacent to the central axis of the light exit surface of the light source 112 . In addition, the first end 131 and the second end 132 of the sterilization space may be located at or adjacent to the outermost angle of the beam angle of the light source 112 .

As such, the sterilization module 100 of the present embodiment may form the collecting unit 120 so that ends of the collecting units 121 adjacent to each other are positioned within the light irradiation area of the light source 112 . Therefore, the sterilization module 100 of the present embodiment allows the light of the light source unit 110 to be irradiated to the entire collecting unit 120 and improves the uniformity of the light irradiated to the collecting unit 120 to improve sterilization efficiency.

In addition, in the sterilization module 100 of this embodiment, the angle between the collection units 121 adjacent to each other and the distance between ends may be freely changed within the light irradiation area of the light source 112 . That is, the sterilization module 100 of this embodiment can adjust the speed of the fluid passing through the collecting unit 120 while maintaining light uniformity. Therefore, the sterilization module 100 of the present embodiment can improve sterilization efficiency by adjusting light uniformity and fluid flow rate.

Referring to FIG. 3 , the sterilization module 200 according to the second embodiment may include a collecting unit 220 , a light source unit 110 and a reflecting unit 250 .

The sterilization module 200 of this embodiment is obtained by adding a reflector 250 to the sterilization module 100 according to the first embodiment of FIG. 1 . That is, the collecting unit 220 and the light source unit 110 of this embodiment are the same as the collecting unit 120 and the light source unit 110 of the sterilization module 100 according to the first embodiment of FIG.

Referring to FIG. 3 , the reflector 250 may be disposed between the light source unit 110 and the collecting unit 220 . In this case, the reflector 250 may be located closer to the collecting unit 220 than the light source unit 110 .

The reflector 250 may be made of a material that reflects light emitted from the light source unit 110 . Also, a material constituting the reflector 250 may vary according to a peak wavelength (center wavelength) of light emitted from the light source 112 . For example, the reflector 250 may be formed of a material having a reflectance of 70% or more for light emitted from the light source unit 110 . Furthermore, the reflector 250 may have a reflectance of 90% or more for light emitted from the light source unit 110 . That is, the reflector 250 may have a transmittance of less than 10% for light emitted from the light source unit 110 .

Referring to FIG. 3 , the reflector 250 may include a plurality of through holes. The fluid may pass through the through hole of the reflector 250 and move to the collecting unit 220 . In this embodiment, the through hole of the collecting unit 220 is the first through hole 225 , and the through hole of the reflecting unit 250 is the second through hole 255 .

For example, the second through hole 255 of the reflector 250 may be formed to have a larger diameter than the first through hole 225 of the collecting part 220 . In addition, the second through hole 255 of the reflector 250 may be formed to have a size exposing the plurality of first through holes 225 of the collecting part 220 . Accordingly, some of the light emitted from the light source unit 110 may be irradiated to the collecting unit 220 through the second through hole 255 of the reflecting unit 250 .

In addition, the reflector 250 may be formed so that the center of the second through hole 255 and the center of the first through hole 225 of the collecting part 220 are not located on the same line. That is, the center of the second through hole 255 of the reflector 250 and the center of the first through hole 225 of the collecting unit 220 may not match. Accordingly, the collecting surface of the collecting unit 220 may be maximally exposed to the light of the light source unit 110 through the second through hole 255 of the reflecting unit 250 .

Since the reflector 250 is formed of a light reflective material, light from the light source unit 110 passing through the second through hole 255 may be scattered by the reflector 250 . Accordingly, the light passing through the second through hole 255 can be irradiated to the collecting unit 220 as widely and uniformly as possible.

In addition, light from the light source unit 110 may be reflected from one surface of the reflector 250 facing the light source unit 110 . At this time, the fluid may be exposed to both the light emitted from the light source unit 110 and the light reflected by the reflector 250 . Therefore, the sterilization efficiency of the fluid can be improved by the reflector 250 .

The reflector 250 of the present embodiment can minimize the resistance that fluid receives by the reflector 250, so that the fluid flows smoothly. Also, the reflector 250 may uniformly irradiate light to the collecting unit 220 . In addition, the reflector 250 may increase the amount of time the fluid is exposed to light or the amount of light irradiated to the fluid. Therefore, the sterilization efficiency of the sterilization module 200 according to the present embodiment may be improved by the reflector 250 .

When the flow rate or flow rate of the fluid increases, the pressure applied to the collecting unit 220 increases, and thus the collecting unit 220 may be deformed or damaged. The reflector 250 of this embodiment may be disposed between the light source unit 110 and the collecting unit 220 to relieve the pressure of the fluid that the collecting unit 220 receives. That is, the reflector 250 may protect the collecting unit 220 from the pressure of the fluid, thereby improving durability and reliability of the sterilization module 200 .

In this embodiment, the reflector 250 may be formed to have a thickness equal to or smaller than that of the collecting unit 220 . Here, the thickness is the length between one side into which the fluid is introduced and the other side through which the fluid is discharged.

Also, in this embodiment, the reflector 250 may have greater rigidity than the collecting unit 220 . For example, the reflector 250 may be formed of a metal material. Therefore, even if the thickness of the reflecting part 250 is less than the thickness of the collecting part 220, the collecting part 220 can be protected without being deformed or damaged by the pressure of the fluid.

4 is an exemplary view showing a sterilization module according to a third embodiment of the present invention

The sterilization module 300 according to the third embodiment is different from the sterilization module 200 according to the second embodiment of FIG. 2 in the structure of the collecting unit 320 and the reflection unit 350.

The collecting unit 320 and the reflecting unit 350 of the sterilization module 300 of this embodiment may have a structure in which a plurality of layers are stacked.

The collection unit 320 of this embodiment may include a first collection layer 321 and a second collection layer 325 .

The first collection layer 321 and the second collection layer 325 may be formed of the same material. The first collection layer 321 and the second collection layer 325 may respectively collect contamination sources of the fluid passing through the collection unit 320 . That is, contaminants included in the fluid may be double-removed from the fluid while passing through the collecting unit 320 .

Also, the first collection layer 321 and the second collection layer 325 may be formed of different materials. At this time, the first collection layer 321 and the second collection layer 325 may collect all contaminants included in the fluid. In addition, the first collection layer 321 and the second collection layer 325 may collect certain types of contaminants better than other types of contaminants depending on the material. That is, at least one of the first collection layer 321 and the second collection layer 325 may be formed of a material optimized for collecting a specific type of pollutant. Alternatively, the first collection layer 321 and the second collection layer 325 may be formed of different materials to be optimized for collecting different specific types of pollutants.

Each of the first collection layer 321 and the second collection layer 325 may have a plurality of through holes through which fluid passes. The through hole of the first collection layer 321 is the 1-1 through hole 322 , and the through hole of the second collection layer 325 is the 1-2 through hole 326 . In this embodiment, the 1-1st through hole 322 and the 1-2nd through hole 326 may have the same diameter. Alternatively, the 1-1st through hole 322 and the 1-2nd through hole 326 may have different diameters as shown in FIG. 4 .

In addition, the first collection layer 321 and the second collection layer 325 may be formed so that the center of the 1-1st through hole 322 and the center of the 1-2nd through hole 326 are offset from each other. . When the center of the 1-1 through hole 322 coincides with the center of the 1-2 through hole 326, the fluid that has passed through the 1-1 through hole 322 is transferred to the 1-2 through hole 326 as it is. ), so that the pollutant collection efficiency of the second collection layer 325 is reduced. When the center of the 1-1 through hole 322 and the center of gravity of the 1-2 through hole 326 are misaligned, at least a portion of the fluid passing through the 1-1 through hole 322 is transferred to the second collection layer 325. ) The contaminants may be collected in the second filter unit by contacting the collecting surface of the second filter unit. Therefore, the first collection layer 321 and the second collection layer 325 are formed so that the center of the 1-1st through hole 322 and the center of the 1-2nd through hole 326 are offset from each other, thereby preventing contamination. The collection efficiency for can be improved.

In addition, the first collection layer 321 and the second collection layer 325 may be disposed to be in close contact with each other or may be disposed to be spaced apart from each other.

The reflector 350 of this embodiment may include a first reflective layer 351 and a second reflective layer 355 .

The first reflective layer 351 and the second reflective layer 355 may be formed of the same material or different materials.

Also, the first reflective layer 351 and the second reflective layer 355 may include a plurality of through holes through which fluid passes. The through hole of the first reflective layer 351 is the 2-1 through hole 352 , and the through hole of the second reflective layer 355 is the 2-2 through hole 356 .

In this embodiment, the 2-1st through hole 352 and the 2-2nd through hole 356 may have the same diameter. Also, the 2-1st through hole 352 and the 2-2nd through hole 356 may have different diameters as shown in FIG. 4 .

In addition, the first reflective layer 351 and the second reflective layer 355 may be formed so that the center of the 2-1 through hole 352 and the center of the 2-2 through hole 356 are offset from each other. In addition, both the 2-1 through hole 352 of the first reflective layer 351 and the 2-2 through hole 356 of the second reflective layer 355 are the 1-1 through hole of the first collection layer 321. It may be formed to have a larger diameter than the hole 322 and the first-second through hole 326 of the second collection layer 325 .

In addition, the first reflective layer 351 and the second reflective layer 355 include at least one of the 2-1st through holes 352 and 2-2nd through holes 356 and the 1-1st through hole 322. At least one of the first and second through holes 326 and the central axis may be misaligned.

Therefore, through the 2-1 through hole 352 of the first reflective layer 351 and the 2-2 through hole 356 of the second reflective layer 355, the collection surface of the first collection layer 321 and the second At least a portion of the collection surface of the collection layer 325 may be exposed to light. The first collection layer 321 and the second collection layer 325 may be covered by the first reflective layer 351 and the second reflective layer 355 so that the light from the light source unit 110 is not directly irradiated. Light reflected by the first reflective layer 351 and the second reflective layer 355 may be scattered and irradiated to this portion.

In addition, the first reflective layer 351 and the second reflective layer 355 may be formed to be in close contact with or spaced apart from each other. When the first reflective layer 351 and the second reflective layer 355 are spaced apart, light reflection may repeatedly occur in the spaced apart space. Accordingly, the fluid between the first reflective layer 351 and the second reflective layer 355 may be continuously exposed to the reflected light. Therefore, the fluid can be sterilized by the reflected light even between the first reflective layer 351 and the second reflective layer 355 where the light emitted from the light source unit 110 does not reach.

As such, the sterilization module 300 of the present embodiment improves the collection efficiency of contaminants by forming the reflector 350 and the collection unit 320 as a plurality of layers, and increases the sterilization efficiency by increasing the time the contaminants are exposed to light. can improve

The front of the collecting unit 420 is one side facing the light source unit 110, and the rear side is the opposite side of the front side. In this case, the first reflector 450 and the second reflector 460 may be disposed adjacent to the collecting unit 420 and spaced apart from the collecting unit 420 . Accordingly, the fluid passes through the second reflection part 460 after passing through the first reflection part 450 and the collecting part 420 .

The second reflector 460 may reflect light passing through the collecting unit 420 . The light reflected by the second reflector 460 may be irradiated to the fluid passing through the collecting unit 420 . Accordingly, contaminants that are not sterilized while passing through the first reflector 450 and the collecting unit 420 may be exposed to the light reflected by the second reflector 460 to be sterilized.

The second reflector 460 may be the same as the reflector 250 of the sterilization module 200 of the second embodiment of FIG. 3 or the reflector 350 of the sterilization module 300 of the third embodiment of FIG. 4 . . That is, the second reflector 460 may be formed as a single layer or may include a plurality of layers.

At this time, the reflective material of the collecting unit 520 is reflected at various angles so that the light is uniformly irradiated to the entire space between the light source unit 110 and the collecting unit 520 .

Contaminants of the fluid may be collected in a portion of the collecting unit 520 made of a collecting material without a reflective material. For example, the contaminant may be collected on a part of the front surface of the collecting unit 520 where the reflective material is not formed or on an inner wall forming a through hole (not shown) of the collecting unit 520 . In this embodiment, light is scattered in various directions by the reflective material of the collecting unit 520 and may be irradiated to the inner wall of the through hole. Therefore, in the present embodiment, the pollutants collected by the collecting unit 520 may be sterilized by being exposed to light emitted from the light source unit 110 or exposed to light reflected by a reflective material.

That is, the sterilization module 500 of the present embodiment can improve sterilization efficiency by improving the uniformity of light in a space through which fluid passes through a reflective material and maximally exposing the fluid and contaminants to light.

In addition, durability of the collecting unit 520 may be improved by the reflective material. Therefore, the collecting unit 520 of this embodiment can be prevented from being damaged or broken by the pressure of the fluid. Thus, the durability and reliability of the sterilization module 500 of this embodiment can be improved.

It may be a carbide substrate, a gallium nitride substrate, an aluminum nitride substrate, a silicon substrate, or the like. A side surface of the growth substrate 1100 may include an inclined surface, and thus extraction of light generated from the active layer 1112 may 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 includes the first conductivity-type semiconductor layer 1111 and the second conductivity-type semiconductor layer 1113. can be placed in between.

The first conductivity-type semiconductor layer 1111 may include an n-type impurity (eg, Si), and the second conductivity-type semiconductor layer 1113 may include a p-type impurity (eg, Mg). there is. Also, the opposite may be true.

The active layer 1112 may include a multi-quantum well structure (MQM). When a forward bias is applied to the light source 1000, light is emitted while electrons and holes are combined in the active layer 1112. The first conductivity-type semiconductor layer 1111, the active layer 1112, and the second conductivity-type semiconductor layer 1113 are formed on a growth substrate ( 1100) can be grown on.

The light source 1000 may include at least one mesa M including an active layer 1112 and a second conductive semiconductor layer 1113 . The mesa M may include a plurality of protrusions, and the plurality of protrusions may be spaced apart from each other. It is not limited thereto, and the light source 1000 may include a plurality of mesas M spaced apart from each other. The side surface of the mesa M may be formed to be inclined by using a technique such as photoresist reflow, and the inclined side surface of the mesa M may improve light emitting efficiency generated in the active layer 1112 .

The first conductivity-type semiconductor layer 1111 may include a first contact region R1 and a second contact region R2 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, the portion excluding the mesa M is the first conductivity type semiconductor layer. It becomes the contact region which is the exposed upper surface of the type semiconductor layer 1111. The first electrode 1140 may be electrically connected to the first conductive semiconductor layer 1111 by contacting the first contact region R1 and the second contact region R2 .

It may be disposed along the outer edge of 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 direction of the major axis may be 0.5 times or more than the length of one side of the light source 1000 . In this case, since the contact area between the first electrode 1140 and the first conductivity type semiconductor layer 1111 may increase, the current flowing from the first electrode 1140 to the first conductivity type semiconductor layer 1111 is more effective. It can be dissipated, so 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 as the mesa M. The second electrode 1120 includes the reflective metal layer 1121 and may further include a barrier metal layer 1122, and the barrier metal layer 1122 may cover top and side surfaces of the reflective metal layer 1121.

For example, the reflective metal layer 1121 may be formed by depositing and patterning Ag, Ag alloy, Ni/Ag, NiZn/Ag, or TiO/Ag layers.

Meanwhile, the barrier metal layer 1122 may be formed of Ni, Cr, Ti, Pt, Au, or a composite layer thereof, and specifically, Ni/Ag/[Ni/ Ti]2/Au/Ti may be a composite layer, and more specifically, at least a portion of the upper surface of the second electrode 1120 may include a Ti layer having a thickness of 300 Å. When the region of the upper surface of the second electrode 1120 in contact with the first insulating layer is made of a Ti layer, the adhesive strength between the first insulating layer 1130 and the second electrode 1120 is improved, thereby increasing the reliability of the light source 1000. can be improved

The first insulating layer 1130 may partially expose the first contact region R1 and the second contact region R2. In detail, 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 cover the first conductive semiconductor layer 1111. At least a portion of the first contact region R1 may be exposed by covering only a portion of the first contact region R1 between the periphery and the mesa M.

The first insulating layer 1130 may be disposed on the second contact region R2 and along the periphery 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 the area where the first contact region R1 and the first electrode 1140 come into contact.

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

A region where the first contact region R1 and the first electrode 140 come into contact is disposed along the entire outer perimeter of the upper surface of the first conductivity type semiconductor layer. Specifically, the region where the first contact region R1 and the first electrode 1140 come into contact may be disposed to be adjacent to all four side surfaces of the first conductive semiconductor layer 1111 and completely surround the mesa M. can In this case, since the contact area between the first electrode 1140 and the first conductivity type semiconductor layer 1111 may increase, the current flowing from the first electrode 1140 to the first conductivity type semiconductor layer 1111 is more effective. It can be dissipated, so the forward voltage can be further reduced.

In one embodiment of the present disclosure, the first electrode 1140 and the second electrode 1120 of the light source 1000 may be mounted on the substrate 1100 directly or through pads.
