The unit 160, an information determiner 170, and a second sensing unit 180 are included.

The light emitting module unit 110 is disposed in an interior of a vehicle and emits ultraviolet (UV) ultraviolet light having deep germicidal power, for example, deep ultraviolet (DUV) light. Herein, the interior of the vehicle may mean an interior space of the vehicle in which the driver or the occupant of the vehicle is located, and may include a trunk. Hereinafter, light emitted from the light emitting module unit 110 will be described as deep ultraviolet light. However, the embodiment is not limited thereto and may be applied to light of various wavelength bands having bactericidal power.

3 is a graph showing the sterilizing power for each wavelength band of light, the horizontal axis represents the wavelength λ, and the vertical axis represents the sterilizing power, respectively.

Referring to FIG. 3, the bactericidal power may be maximized when the light has the second wavelength λ2, and the bactericidal power of the light may be ensured when the light has the first and third wavelengths λ1 and λ3. That is, when the wavelength of the light emitted from the light emitting module unit 110 is smaller than the first wavelength λ1 or larger than the third wavelength λ3, the sterilizing power may be lowered. Therefore, according to the embodiment, the wavelength of the light emitted from the light emitting module unit 110 may be the first wavelength λ1 to the third wavelength λ3. That is, the wavelength band of deep ultraviolet light may be 100 nm (= λ1) to 280 nm (= λ3).

It may also include, but is not limited to this.

At least one deep ultraviolet LED 114 may be mounted on the substrate 112. The deep ultraviolet LED 114 is disposed in an interior of a vehicle and emits deep ultraviolet light.

Referring to FIG. 4, the deep ultraviolet LED 114 has a flip bonding structure. The deep ultraviolet LED 114 includes a substrate 10, a buffer layer 12, a light emitting structure 14, first and second electrodes 16A and 16B, first and second bumps 18A and 18B, first and second Second metal layer (or electrode pad) 22A, 22B, protective layer 24, submount 26, first and second package bodies 20A, 20B, insulator 30, first and second Wires 42 and 44 and molding member 50.

In order to improve the difference in thermal expansion coefficient and lattice mismatch between the substrate 10 and the light emitting structure 14, a buffer layer (or transition layer) 12 may be disposed between them 10, 14. The buffer layer 12 may include, but is not limited to, at least one material selected from the group consisting of Al, In, N, and Ga, for example. In addition, the buffer layer 12 may have a single layer or a multilayer structure.

The light emitting structure 14 includes a first conductive semiconductor layer 14A, an active layer 14B, and a second conductive first and second semiconductor layers 14C and 14D, which are sequentially disposed below the buffer layer 12. .

The first conductive semiconductor layer 14A is disposed under the buffer layer 12, and may be implemented as a compound semiconductor such as a III-V group or a II-VI group doped with the first conductive dopant. Dopants may be doped. When the first conductivity-type semiconductor layer 14A is an n-type semiconductor layer, the first conductivity-type dopant may be an n-type dopant and may include Si, Ge, Sn, Se, Te, but is not limited thereto.

For example, the first conductive semiconductor layer 14A has a composition formula of Al _x In _y Ga _(1-xy) N (0 ≦ x ≦ 1, 0 ≦ y ≦ 1, 0 ≦ x + y ≦ 1). It may include a semiconductor material. The first conductive semiconductor layer 14A may include at least one of GaN, InN, AlN, InGaN, AlGaN, InAlGaN, AlInN, AlGaAs, InGaAs, AlInGaAs, GaP, AlGaP, InGaP, AlInGaP, and InP.

The active layer 14B is disposed under the first conductivity type semiconductor layer 14A, and electrons (or holes) injected through the first conductivity type semiconductor layer 14A and the second conductivity type first and second semiconductor layers. Holes (or electrons) injected through 14C and 14D meet each other and emit light having energy determined by an energy band inherent in the material forming the active layer 14B.

The active layer 14B may include at least one of a single well structure, a multi well structure, a single quantum well structure, a multi quantum well structure (MQW), a quantum-wire structure, or a quantum dot structure. It can be formed as one.

The well layer / barrier layer of the active layer 14B may be formed of one or more pair structures of InGaN / GaN, InGaN / InGaN, GaN / AlGaN, InAlGaN / GaN, GaAs (InGaAs) / AlGaAs, GaP (InGaP) / AlGaP. However, the present invention is not limited thereto. The well layer may be formed of a material having a bandgap energy lower than the bandgap energy of the barrier layer.

A conductive clad layer (not shown) may be formed on or under the active layer 14B. The conductive clad layer may be formed of a semiconductor having a band gap energy higher than the band gap energy of the barrier layer of the active layer 14B. For example, the conductive clad layer may include GaN, AlGaN, InAlGaN, or a superlattice structure. In addition, the conductive clad layer may be doped with n-type or p-type.

According to the embodiment, the active layer 14B emits light in the deep ultraviolet wavelength band.

The second conductivity type first and second semiconductor layers 14C and 14D may be disposed under the active layer 14B and may be formed of a semiconductor compound. It can be implemented with a compound semiconductor, such as group III-V or II-VI. For example, the second conductivity type first and second semiconductor layers 14C and 14D may be formed of In _x Al _y Ga _1-xy N (0 ≦ x ≦ 1, 0 ≦ y ≦ 1, 0 ≦ x + y ≦ 1). And a semiconductor material having a compositional formula. The second conductivity type first and second semiconductor layers 14C and 14D may be doped with a second conductivity type dopant. When the second conductive first and second semiconductor layers 14C and 14D are p-type semiconductor layers, the second conductive dopant may be a p-type dopant and may include Mg, Zn, Ca, Sr, and Ba. .

The first conductive semiconductor layer 14A may be an n-type semiconductor layer, and the second conductive first and second semiconductor layers 14C and 14D may be a p-type semiconductor layer. Alternatively, the first conductive semiconductor layer 14A may be a p-type semiconductor layer, and the second conductive first and second semiconductor layers 14C and 14D may be an n-type semiconductor layer.

The light emitting structure 14 may be implemented as any one of an N-P junction structure, a P-N junction structure, an N-P-N junction structure, and a P-N-P junction structure.

According to the embodiment, when the active layer 14B emits light in the deep ultraviolet wavelength band as described above, the second conductivity-type first semiconductor layer 14C disposed under the active layer 14B includes AlGaN. The second conductive second semiconductor layer 14D disposed under the second conductive first semiconductor layer 14C may include GaN or InAlGaN. In addition, the first conductivity-type semiconductor layer 14A may also include AlGaN. This is because AlGaN absorbs less light in the deep ultraviolet wavelength band than GaN or InAlGaN.

If the first conductivity type is n type and the second conductivity type is p type, the second conductivity type first semiconductor layer 14C may serve as an electron blocking layer (EBL). Alternatively, the second conductivity-type first semiconductor layer 14C serving as the electron blocking layer may have an AlGaN / AlGaN superlattice layer structure or an AlGaN bulk layer structure.

Meanwhile, although GaN absorbs more light in the ultraviolet wavelength band than AlGaN, the second conductive second semiconductor layer 14D, which may be implemented with GaN, is formed of the second electrode 16B and the second conductive first. The reason why the semiconductor layer 14C is disposed is that the second conductivity type second semiconductor layer 14D smoothly supplies holes from the second electrode 16B to the active layer 14B so that the electrical characteristics of the deep ultraviolet LED 114 are improved. Because it improves.

Meanwhile, the first electrode 16A is disposed under the first conductive semiconductor layer 14A exposed by mesa etching. The first electrode 16A may include a material in ohmic contact, and may play a role of ohmic so that a separate ohmic layer (not shown) may not need to be disposed, and a separate ohmic layer may be disposed below the first electrode 16A. It may be arranged.

The second electrode 16B is disposed under the second conductive second semiconductor layer 14D.

Each of the first and second electrodes 16A and 16B may reflect or transmit light emitted from the active layer 14B without being absorbed, and may be the first conductivity type semiconductor layer 14A and the second conductivity type second semiconductor. It can be formed of any material that can be grown on top of each of the layers 14D. For example, each of the first and second electrodes 16A and 16B may be formed of a metal, and may include Ag, Ni, Al, Rh, Pd, Ir, Ru, Mg, Zn, Pt, Au, Hf, and their It can be made in an optional combination.

In addition, the second electrode 16B may be formed in a single layer or multiple layers of a reflective electrode material having ohmic characteristics. If the second electrode 16B plays an ohmic role, an additional ohmic layer (not shown) may not be formed.

Subsequently, referring to FIG. 4, the submount 26 may be formed of, for example, a semiconductor substrate such as AlN, BN, silicon carbide (SiC), GaN, GaAs, Si, and the like, and the semiconductor having excellent thermal conductivity is not limited thereto. It may be made of a material. In addition, an element for preventing electrostatic discharge (ESD) in the form of a zener diode may be included in the submount 26.

The first and second metal layers 22A and 22B are spaced apart from each other in the horizontal direction on the submount 26. The first bump 18A is disposed between the first metal layer 22A and the first electrode 16A, and the second bump 18B is disposed between the second metal layer 22B and the second electrode 16B.

The first electrode 16A is electrically connected to the first metal layer 22A of the submount 26 through the first bump 18A, and the second electrode 16B is submounted through the second bump 18B. And is electrically connected to the second metal layer 22B of (26).

Although not shown, a first upper bump metal layer (not shown) is further disposed between the first electrode 16A and the first bump 18A, and between the first metal layer 22A and the first bump 18A. A first lower bump metal layer (not shown) may be further disposed. Here, the first upper bump metal layer and the first lower bump metal layer serve to indicate a position where the first bump 18A is to be located. Similarly, a second upper bump metal layer (not shown) is further disposed between the second electrode 16B and the second bump 18B, and a second lower bump is disposed between the second metal layer 22B and the second bump 18B. Metal layers (not shown) may be further disposed. Here, the second upper bump metal layer and the second lower bump metal layer serve to indicate a position where the second bump 18B is to be located.

If the submount 26 is made of a material having electrical conductivity such as Si, a protective layer between the first and second metal layers 22A and 22B and the submount 26 as illustrated in FIG. 4. 24 may be further arranged. Here, the protective layer 24 may be made of an insulating material.

The first and second package bodies 20A and 20B are disposed on the substrate 112. Since the deep ultraviolet LED 114 emits deep ultraviolet light, the first and second package bodies 20A and 20B may be made of aluminum, but are not limited thereto.

In FIG. 4, the submount 26 is shown disposed above the second package body 20B, but the embodiment is not limited thereto. That is, the submount 26 may be disposed on the first package body 20A instead of the second package body 20B. The first and second metal layers 22A and 22B are connected to the first and second package bodies 20A and 20B by first and second wires 42 and 44, respectively. When the first and second package bodies 20A and 20B are made of an aluminum material having electrical conductivity, the insulator 30 may electrically separate the first package body 20A and the second package body 20B from each other. Play a role.

The first conductive semiconductor layer 14A is formed of a substrate 112 through a first electrode 16A, a first bump 18A, a first metal layer 22A, a first wire 42 and a first package body 20A. ) Can be electrically connected. In addition, the second conductivity type first and second semiconductor layers 14C and 14D may include a second electrode 16B, a second bump 18B, a second metal layer 22B, a second wire 44 and a second package. The body 20B may be electrically connected to the substrate 112.

The molding member 50 is filled in the cavities formed by the first and second package bodies 20A, 20B so that the above-described parts 10, 12, 14, 16A, 16B, 18A, 18B, 22A, 22B, 24, 26) can be surrounded and protected. In addition, the molding member 50 may include a phosphor to change the wavelength of deep ultraviolet light emitted from the active layer 14B.

The structure of the deep ultraviolet LED 114 illustrated in FIG. 4 is just one example, and the deep ultraviolet LED 114 used in the automotive sterilization apparatus 100A of the embodiment is not limited thereto and may be implemented in various other forms. Of course.

On the other hand, according to another embodiment, in order to emit light of the deep ultraviolet wavelength band, the light emitting module unit 110 may be implemented as a deep ultraviolet lamp (lamp). The deep ultraviolet lamp is disposed in an interior of a vehicle and emits deep ultraviolet light.

Deep UV LEDs have a longer lifespan than deep UV lamps, and have a very uniform light output, providing stable sterilizing power even for a long time, and are more environmentally friendly. Further, as will be described later, the deep ultraviolet LED has a low operating voltage that can be driven by an automotive battery, but the deep ultraviolet lamp may have an operating voltage higher than that of the deep ultraviolet LED. In addition, deep ultraviolet lamps may have more risk factors such as debris in case of car accident breakage than deep ultraviolet LEDs. Therefore, the light emitting module unit 110 may be implemented as a deep ultraviolet LED rather than a deep ultraviolet lamp.

On the other hand, the light emission control unit 120 is a point at which the deep ultraviolet light is emitted from the light emitting module unit 110 to sterilize the interior of the vehicle, the end point to stop the emission of the deep ultraviolet light from the light emitting module unit 110 to stop sterilization And at least one of intensity of deep ultraviolet light. That is, the light emitting module unit 110 may emit or stop deep ultraviolet light under the control of the light emission controller 120, and may emit deep ultraviolet light at a determined intensity under the control of the light emission controller 120.

Automotive sterilization apparatus 100A according to an embodiment may further include a first sensing unit 130. The first sensing unit 130 detects the presence of a driver or a passenger in the interior of the vehicle and outputs the detected result to the light emission controller 120. To this end, the first sensing unit 130 may be implemented as a motion sensor or a thermal sensor (or an infrared sensor). The light emission controller 120 controls the light emitting module unit 110 in response to the result sensed by the first sensing unit 130. That is, when the light emitting module unit 110 emits deep ultraviolet light in a state where a driver or a passenger is present in the interior of a vehicle, the driver or passenger may be damaged by deep ultraviolet light. Therefore, in order to prevent this, when it is recognized that the driver or the passenger is present in the interior of the vehicle based on the result detected by the first sensing unit 130, the light emission controller 120 does not emit light from the light emitting module unit 110. To prevent it.

Automotive sterilization apparatus 100A according to an embodiment may further include a power supply unit 140. The power supply unit 140 generates power required for the operation of the light emitting module unit 110 and supplies the generated power to the light emitting module unit 110.

The power supply unit 140 may include a battery of an automobile. That is, although the battery of the vehicle may be used as the power supply unit 140, the embodiment is not limited thereto. According to another embodiment, a separate power supply unit 140 may be disposed in addition to the battery of the vehicle.

5 is a block diagram of a sterilization apparatus 100B for automobiles according to another embodiment.

If the light emitting module unit 110 is implemented by the deep ultraviolet LED 114, the operating voltage required by the deep ultraviolet LED 114 may be less than 10 volts, and thus only a vehicle battery may be used without the booster 190. However, when the light emitting module unit 110 is implemented with a deep ultraviolet lamp, the required operating voltage of the deep ultraviolet lamp is 22.5 volts to 100 volts, which is very high. Therefore, the automotive sterilization apparatus 100B may further include a booster 190 in addition to the power supply 140. Except for this, the vehicle sterilization apparatus 100B illustrated in FIG. 5 is the same as the vehicle sterilization apparatus 100A illustrated in FIG. 2, and therefore, the same reference numerals are used, and the vehicle sterilization apparatus 100B illustrated in FIG. 5. Duplicate description of) is omitted or replaced with the description of the automotive sterilization device (100A) illustrated in FIG.

The booster 190 of FIG. 5 boosts the voltage of the power supplied from the power supply unit 140 to a voltage necessary for the operation of the light emitting module unit 110 and outputs the boosted voltage to the light emitting module unit 110. . Therefore, the light emitting module unit 110 implemented as a deep ultraviolet lamp may be driven by the boosted voltage output from the boosting unit 190.

On the other hand, referring to Figure 2, the vehicle sterilization apparatus 100A may further include a charge detection unit 150. The charge detection unit 150 detects the charge amount of the battery, and outputs the detected result to the light emission controller 120. In this case, the light emission controller 120 controls whether power is supplied from the power supply unit 140 to the light emitting module unit 110 in response to the result detected by the charge detection unit 150. If the amount of charge in the battery of the vehicle is small, when the light emitting module unit 110 operates, the vehicle battery may be discharged. Therefore, when it is recognized that the amount of charge of the battery is small based on the result detected by the charge amount sensing unit 150, the light emission controller 120 blocks the power supply unit 140 from providing power to the light emitting module unit 110. To prevent the car battery from being discharged in advance.

The charge detection unit 150 may continuously detect the charge of the battery before the light emitting module unit 110 emits light or while the light emitting module 110 emits light. The light emission controller 120 may control the light emitting module unit 110 to stop light emission even while the light emitting module unit 110 emits light by using the result detected by the charge amount detecting unit 150.

The vehicle sterilization apparatus 100A may further include a user interface unit 160. The user interface 160 receives and stores the 'reserved light emission information' reserved by the user of the vehicle, that is, the driver or the passenger. The reserved light emission information may be at least one of a time point at which the deep ultraviolet light is emitted from the light emitting module unit 110, an end point, and the intensity of the deep ultraviolet light. In this case, the light emission controller 120 controls the light emitting module unit 110 in accordance with the reserved light emission information stored in the user interface unit 160. Thus, the user of the vehicle can schedule the sterilization of the vehicle only for the desired period at the desired time. For example, when the user of the car does not use the car at night or at bedtime, when the car is scheduled to be sterilized at night or at bedtime, the user interface unit 160 stores the reserved light emission information. The light emission controller 120 controls power to be supplied from the power supply unit 140 to the light emitting module unit 110 at a reserved time according to the reserved light emission information received from the user interface unit 160 to sterilize the vehicle. As such, in order to allow the deep ultraviolet light to be emitted from the light emitting module unit 110 for a desired period, the light emission controller 120 may include a timer (not shown).

If the user reserves the car to be sterilized at night, the user may drive the car in the unavoidable time period. In this case, the first sensing unit 130 detects the driver and the passenger and outputs the detected result to the light emission control unit 120. The light emission control unit 120, even if the user reserves the vehicle to be sterilized at night, when the driver or the passenger is inside the car through the sensed result received from the first sensing unit 130, the light emission module unit 110. Can be controlled not to emit deep ultraviolet light. As a result, it is possible to prevent the driver or the passenger from being exposed to deep ultraviolet light to be damaged in advance.

The vehicle sterilization apparatus 100A may further include an information determination unit 170. When there is no reserved light emission information in the user interface unit 160 or when the user of the vehicle requests sterilization of the car by default light emission information instead of the reserved light emission information even if there is reserved light emission information, the light emission control unit 120 controls the light emitting module unit 110 by default light emission information.

The information determiner 170 may analyze a driving time zone of the vehicle and determine default emission information based on the analyzed result. For example, when the vehicle is mainly operated only during the daytime hours from 9:00 am to 7:00 pm, the information determiner 170 may provide default emission information so that the light emitting module 110 emits light at night time periods other than the daytime time zone. You can decide.

The vehicle sterilization apparatus 100A may further include a second sensing unit 180. The second sensing unit 180 detects whether the vehicle is driven and outputs the detected result to the light emission controller 120. The light emission controller 120 controls the light emitting module unit 110 in response to the result sensed by the second sensing unit 180. For example, when the first sensing unit 130 does not properly sense a driver and a passenger, the light emitting module unit 110 may emit deep ultraviolet light during driving of the vehicle. In preparation for such a situation, when the second sensing unit 180 is auxiliary, the light emitting controller 120 may stop light emission of the light emitting module unit 110 while the driver is in the interior of the car. have.

For example, the light emission controller 120 determines that the vehicle is in operation when it is recognized that the vehicle is turned on based on the result detected by the second sensing unit 180, and the deep ultraviolet light is emitted from the light emitting module unit 110. It can be controlled so as not to be released.

FIG. 6 is a diagram schematically illustrating an interior of a vehicle 200 for explaining a position in which the light emitting module unit 110 is disposed in the sterilizing apparatus 100A or 100B for a vehicle according to the embodiment.

The light emitting module unit 110 may be disposed such that deep ultraviolet light is emitted toward a part where a driver or a passenger of the vehicle contacts. This is because the infection of the microorganisms affecting the driver or the passenger is mainly to sterilize this part because it is introduced into the interior of the vehicle through the driver or the passenger's body.

The light emitting module unit 110 may include the bottoms 232 and 234 of the vehicle, the front and rear seats 236 and 238, the inside of the door (not shown), and the bottom of the trunk 241. At least one of the 240, the side (not shown), and the shelf 242 of the back sheet 238 may be disposed to radiate deep ultraviolet light.

The light emitting module unit 110 is disposed inside the interior light 220 of the vehicle 211 or around 212, 213 around the interior light 220, so that the floor 232, 234, the seats 236, 238, and the rear seat of the vehicle. Deep ultraviolet light may be irradiated evenly toward the shelf 242 of 238.

When the light emitting module unit 110 is disposed at the side of the steering wheel 214, the light emitting module unit 110 is closer to the inside of the door or the floor 232 of the vehicle, so that the inside of the door without increasing the intensity of the deep ultraviolet light. I can sterilize the floor 232 of the car.

7 is a flowchart for explaining a sterilization method of a sterilization apparatus for a vehicle according to an embodiment.

The sterilization method according to the embodiment illustrated in FIG. 7 may be performed in the automotive sterilization apparatus 100A or 100B illustrated in FIG. 1 or 5.

First, the first sensing unit 130 detects whether the driver or the passenger is in the interior of the vehicle 200 and outputs the detected result to the light emission controller 120 (operation 310).

If it is determined that the driver or the passenger is in the vehicle interior based on the result detected by the first sensing unit 130, the light emission controller 120 controls the light emitting module 110 not to emit deep ultraviolet light (320). step).

However, when it is determined that the driver or the passenger is not in the interior of the vehicle based on the result detected by the first sensing unit 130, the light emission controller 120 charges the amount of charge of the vehicle battery based on the result detected by the charge detection unit 150. It is determined whether or not the threshold amount or more (step 330). Here, the threshold amount means the amount of charge of the battery that is expected to discharge the battery when the light emitting module unit 110 operates.

If it is determined that the amount of charge of the battery is less than the threshold amount, the light emission controller 120 controls the light emitting module 110 to prevent the deep ultraviolet light from being emitted (step 320).

Although step 330 is shown to be performed after step 310, the embodiment is not limited thereto. That is, step 330 may be performed before step 310 or may be performed during, before, or after step 340 to 380. Accordingly, when the amount of charge of the battery is insufficient even while the light emitting module unit 110 emits deep ultraviolet light, the light emission control unit 120 may control the light emitting operation of the light emitting module unit 110 to stop, thereby discharging the battery. This can be prevented.

If it is determined that the battery charge amount is greater than or equal to the threshold amount, the light emission controller 120 controls the power supply unit 140 to supply power to the light emitting module unit 110 (operation 340). In this case, when the light emitting module unit 110 is implemented as a deep ultraviolet lamp, the boosting unit 190 shown in FIG. 5 boosts the power output from the power supply unit 140 and displays the result of the boosted light emitting module unit 110. Will output

After operation 340, the light emission controller 120 determines whether the vehicle is in operation based on the result detected by the second sensor 180 (operation 350). If it is determined that the vehicle is in operation, the light emission controller 120 controls the light emitting module 110 to not emit deep ultraviolet light (S320). Here, when the vehicle is turned on, the vehicle is recognized as being in operation.

However, if it is determined that the vehicle is not in operation, the light emission controller 120 determines whether there is reserved light emission information stored in the user interface 160 (operation 360).

If it is determined that there is reserved light emission information, the light emission controller 120 controls the light emission of the light emitting module unit 110 according to the reserved light emission information (operation 370). However, if it is determined that there is no reserved light emission information, the light emission controller 120 controls the light emitting module unit 110 according to the default light emission information (operation 380).

Car sterilization apparatus (100A, 100B) according to the above embodiment can sterilize harmful microorganisms, etc. introduced into the interior of the vehicle 200 by using deep ultraviolet light is dangerous for infants, infants or the elderly in the car Protect against germs.
