Here, the interior of the automobile means an internal space of a vehicle having a driver or an occupant of the automobile, and may include a trunk. Hereinafter, it is assumed that the light emitted from the light emitting module section 110 is a deep ultraviolet ray. However, the embodiment is not limited to this, and it goes without saying that the present invention can also be applied to light of various wavelength bands having sterilizing power.

The first conductive semiconductor layer 14A may include one or more of GaN, InN, AlN, InGaN, AlGaN, InAlGaN, AlInN, AlGaAs, InGaAs, AlInGaAs, GaP, AlGaP, InGaP, AlInGaP and InP.

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

The well layer / barrier layer of the active layer 14B may be formed of any one or more of a pair structure of InGaN / GaN, InGaN / InGaN, GaN / AlGaN, InAlGaN / GaN, GaAs (InGaAs) / AlGaAs, GaP (InGaP) But are not limited thereto. The well layer may be formed of a material having a band gap energy lower than the band gap energy of the barrier layer.

A conductive clad layer (not shown) may be formed on and / or below the active layer 14B. The conductive cladding 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.

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

The first and second semiconductor layers 14C and 14D of the second conductivity type are disposed under the active layer 14B and may be formed of a semiconductor compound. III-V, or II-VI group. For example, the second conductive 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 + Semiconductor material having a composition formula. The second conductive type first and second semiconductor layers 14C and 14D may be doped with a second conductive type dopant. When the first and second semiconductor layers 14C and 14D of the second conductivity type are p-type semiconductor layers, the second conductivity type dopant may include Mg, Zn, Ca, Sr, and Ba as a p-type dopant .

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

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 conductive type first semiconductor layer 14C may serve as an electron blocking layer (EBL). Alternatively, the second conductive type first semiconductor layer 14C serving as the electron blocking layer may have an AlGaN / AlGaN super lattice layer structure or an AlGaN bulk layer structure.

On the other hand, although the GaN further absorbs light in the ultraviolet wavelength band than AlGaN, the second conductive type second semiconductor layer 14D, which can be realized by GaN, is formed by the second electrode 16B and the second conductive type first The reason why the second semiconductor layer 14D is disposed between the semiconductor layers 14C is that the second conductive type second semiconductor layer 14D uniformly supplies holes from the second electrode 16B to the active layer 14B, .

Meanwhile, the first electrode 16A is disposed under the first conductive type semiconductor layer 14A exposed by mesa etching. The first electrode 16A may include an ohmic contact material and may function as an ohmic layer so that a separate ohmic layer (not shown) may not be disposed, and a separate ohmic layer may be formed under the first electrode 16A .

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

Each of the first and second electrodes 16A and 16B can reflect or transmit the light emitted from the active layer 14B without absorbing it and the first and second electrodes 16A and 16B can transmit / Lt; RTI ID = 0.0 > 14D < / RTI > For example, each of the first and second electrodes 16A and 16B may be formed of a metal, and may be formed of Ag, Ni, Al, Rh, Pd, Ir, Ru, Mg, Zn, Pt, Au, It can be made in an optional combination.

Further, the second electrode 16B may be formed as a single layer or multiple layers of a reflective electrode material having an ohmic characteristic. If the second electrode 16B performs an ohmic function, a separate ohmic layer (not shown) may not be formed.

4, the submount 26 may be formed of a semiconductor substrate such as AlN, BN, silicon carbide (SiC), GaN, GaAs, Si, or the like, Material. In addition, a device 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 disposed on the submount 26 in a horizontal direction. 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 via the first bump 18A and the second electrode 16B is electrically connected to the submount 26B through the second bump 18B, Is electrically connected to the second metal layer (22B)

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 a second upper bump metal layer (not shown) is disposed 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 the 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 metal layer (not shown) is disposed between the second metal layer 22B and the second bump 18B. A metal layer (not shown) may be further disposed. Here, the second upper bump metal layer and the second lower bump metal layer serve to indicate the position where the second bump 18B is to be positioned.

If the submount 26 is made of a material having electrical conductivity such as Si, a protective layer (not shown) may be formed between the first and second metal layers 22A and 22B and the submount 26 as illustrated in FIG. 24 may be further disposed. 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. The first and second package bodies 20A and 20B may be made of aluminum, but are not limited thereto, in order to improve the heat dissipation characteristic since the deep ultraviolet LED 114 emits deep ultraviolet light.

Although the submount 26 is shown as being disposed on the second package body 20B in Fig. 4, the embodiment is not limited to this. 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 formed of an aluminum material having electrical conductivity, the insulator 30 electrically separates the first package body 20A and the second package body 20B from each other It plays a role.

The first conductive semiconductor layer 14A is electrically connected to the substrate 112 through the first electrode 16A, the first bump 18A, the first metal layer 22A, the first wire 42 and the first package body 20A. As shown in FIG. The second conductive type first and second semiconductor layers 14C and 14D are electrically connected to the second electrode 16B, the second bump 18B, the second metal layer 22B, the second wire 44, And may be electrically connected to the substrate 112 through the body 20B.

The molding member 50 is filled in the cavity formed by the first and second package bodies 20A and 20B to form the aforementioned portions 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 merely an example, and the deep ultraviolet LED 114 used in the automotive sanitizer 100A of the embodiment is not limited thereto and may be implemented in various other forms Of course it is.

According to another embodiment, in order to emit light in the deep ultraviolet wavelength band, the light emitting module unit 110 may be embodied as a deep ultraviolet lamp. The deep ultraviolet lamp is placed in the interior of the vehicle and emits deep ultraviolet light.

The deep ultraviolet LED has a longer life than the deep ultraviolet lamp, and the light output is also very uniform, providing stable sterilizing power even when used for a long time and being more environmentally friendly. Also, as described later, the deep ultraviolet LED has a low operating voltage that can be driven by an automobile battery, but a deep ultraviolet lamp may have an operating voltage higher than an operating voltage of a deep ultraviolet LED. Also, in the event of an automobile accident, the deep ultraviolet lamps may have more risk factors such as debris 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.

In order to sterilize the interior of the automobile, the emission control unit 120 controls the emission of the ultraviolet light from the light emitting module unit 110 to stop the emission of the deep ultraviolet light from the light emitting module unit 110, And intensity of deep ultraviolet light. That is, the light emitting module unit 110 may emit deep ultraviolet light or cease emission under the control of the light emission control unit 120, and may emit deep ultraviolet light at a determined intensity under the control of the light emission control unit 120.

The automotive sterilizing apparatus 100A according to the embodiment may further include a first sensing unit 130. [ The first sensing unit 130 senses whether a driver or a passenger is present in the interior of the vehicle and outputs the sensed result to the light emission control unit 120. [ For this, the first sensing unit 130 may be implemented as a motion sensor or a thermal sensor (or an infrared sensor). The light emission control unit 120 controls the light emitting module unit 110 in response to a 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 the automobile, the driver or the passenger may be damaged by the deep ultraviolet light. Accordingly, in order to prevent this, if the driver or the passenger is recognized as being present in the interior of the automobile through the result sensed by the first sensing unit 130, the light emission control unit 120 may not emit light from the light emitting module unit 110 .

The automotive sterilizing apparatus 100A according to the embodiment may further include a power supply unit 140. [ The power supply unit 140 generates a power source necessary 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 can be used as the power supply unit 140, the embodiment is not limited to this. According to another embodiment, a separate power supply unit 140 may be disposed in addition to the battery of the vehicle.

Fig. 5 shows a block diagram of the automotive sanitizer 100B according to another embodiment.

If the light emitting module unit 110 is implemented as a deep ultraviolet LED 114, since the required operating voltage of the deep ultraviolet LED 114 is less than 10 volts, only the automobile battery can be used without the step-up unit 190. [ However, when the light emitting module unit 110 is implemented as a deep ultraviolet lamp, the required operating voltage of the deep ultraviolet lamp is as high as 22.5 volts to 100 volts. Accordingly, the automotive sterilizing apparatus 100B may further include a voltage-boosting unit 190 in addition to the power-supply unit 140. [ Except for this, the automotive sterilizing apparatus 100B illustrated in FIG. 5 is the same as the automotive sterilizing apparatus 100A illustrated in FIG. 2, and thus the same reference numerals are used, and the automotive sterilizing apparatus 100B ) Will be omitted or replaced with a description of the automotive sanitizer 100A illustrated in Fig.

5 raises the voltage of the power source 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 . Accordingly, the light emitting module unit 110 implemented as a deep ultraviolet lamp can be driven by the boosted voltage output from the voltage boosting unit 190.

Referring to FIG. 2, the automotive sterilizer 100A may further include a charged amount sensing unit 150. FIG. The charged amount sensing unit 150 senses the charged amount of the battery and outputs the sensed result to the light emission control unit 120. [ At this time, the light emission control unit 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 amount sensing unit 150. [ If the amount of charge in the battery of the vehicle is small, the vehicle battery may be discharged when the light emitting module unit 110 operates. Accordingly, when the charge amount of the battery is recognized to be low based on the result detected by the charge amount sensing unit 150, the light emission control unit 120 prevents the power supply unit 140 from providing power to the light emitting module unit 110 , So that the discharge of the automobile battery can be prevented in advance.

The charged amount sensing unit 150 can continue to sense the charged amount of the battery even before the light emitting module unit 110 emits light or while emitting light. The light emission control unit 120 can control the light emitting module unit 110 to stop the light emission even during the light emission of the light emitting module unit 110 using the result detected by the charge amount sensing unit 150. [

The automotive sterilizing apparatus 100A may further comprise a user interface unit 160. [ The user interface unit 160 receives the 'reserved light emission information' reserved by the user of the vehicle, that is, the driver or the passenger, from the user and stores it. The reserved light emission information may be at least one of a time when the deep ultraviolet light is emitted from the light emitting module 110 and an intensity of the end point and deep ultraviolet light. In this case, the light emission control unit 120 controls the light emitting module unit 110 according to the reserved light emission information stored in the user interface unit 160. Thus, the user of the vehicle can schedule the disinfection of the vehicle for a desired period of time at a desired time. For example, when the user of the car does not use the car at night or at night, the user interface unit 160 stores the reserved light information when reserving the car to be sterilized at night or at the sleeping time. The light emission control unit 120 controls the power supply unit 140 to supply power 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 so that the vehicle is sterilized. In order to allow the deep ultraviolet light to be emitted from the light emitting module unit 110 during the desired period, the light emission control unit 120 may incorporate a timer (not shown).

If the user has reserved the car to be sterilized at night, however, the user may drive the car at the time of the inevitably reserved time. In this case, the first sensing unit 130 senses the driver and the passenger, and outputs the sensed result to the light emission control unit 120. The light emission control unit 120 may control the light emitting module unit 110 and the light emitting module unit 110 in a case where the driver or the occupant is present in the interior of the vehicle through the sensed result received from the first sensing unit 130, Can be controlled so as not to emit deep ultraviolet light. Therefore, it is possible to prevent the driver or the passenger from being exposed to the deep ultraviolet light and being damaged.

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

The information determination unit 170 may analyze the time zone of the vehicle and determine the default light emission information based on the analyzed result. For example, when the automobile is mainly operated from 9:00 am to 7:00 pm during the weekly time zone, the information determination unit 170 sets the default light emission information so that the light emitting module unit 110 emits light in the night time zone other than the weekly time zone You can decide.

The automotive sterilizing apparatus 100A may further include a second sensing unit 180. [ The second sensing unit 180 senses whether or not the vehicle is driven, and outputs the sensed result to the light emission control unit 120. The light emission control unit 120 controls the light emitting module unit 110 in response to a result sensed by the second sensing unit 180. For example, when the first sensing unit 130 does not properly sense the driver and the occupant, the light emitting module unit 110 may emit deep ultraviolet light during operation of the vehicle. When the second sensing unit 180 is additionally provided in preparation for such a situation, since the driver is in the vehicle room during the operation of the vehicle, the light emission control unit 120 can stop the light emission of the light emitting module unit 110 have.

For example, the light emission control unit 120 determines that the vehicle is running when the start of the vehicle is recognized through the result sensed by the second sensing unit 180, so that the deep ultraviolet light from the light emitting module unit 110 It can be controlled not to be released.

FIG. 6 is a schematic view showing the inside of the automobile 200 for explaining the positions where the light emitting module units 110 are arranged in the automotive sterilizing apparatuses 100A and 100B according to the embodiment.

The light emitting module unit 110 may be disposed such that the deep ultraviolet light is emitted toward the driver or a passenger of the vehicle. This is because microbial infections affecting the driver or occupant are mainly caused by infiltration into the interior of the automobile through the body of the driver or passenger, thereby sterilizing this portion.

The light emitting module unit 110 is mounted on the bottoms 232 and 234 of the automobile and the front and rear sheets 236 and 238 of the automobile and the bottom of the trunk 241 240) and the side (not shown), and the shelf 242 of the back sheet 238, as shown in FIG.

The light emitting module unit 110 is disposed in the vicinity of the inside 211 or the interior light 220 of the automobile and includes the bottoms 232 and 234 of the automobile and the sheets 236 and 238, It is possible to irradiate evenly deep ultraviolet light as a whole toward the shelf 242 of the light source 238.

When the light emitting module unit 110 is disposed on the side 214 of the steering wheel, the light emitting module unit 110 is closer to the inside of the door or the floor 232 of the automobile so that the intensity of the deep ultraviolet light is not increased, Or sterilize the bottom 232 of the car.

When the light emitting module unit 110 is disposed on the back surface 215 of the front sheet 236, the light emitting module unit 110 is closer to the back sheet 238 and the bottom 234, The rear seat 238 and the bottom 234 can be sterilized.

When the light emitting module unit 110 is disposed on the rear surface 216 of the rear seat 238, the light emitting module unit 110 is closer to the shelf 242 of the rear seat 238, It is possible to sterilize the back shelf 242 more efficiently.

7 is a flowchart for explaining a method of sterilizing an automotive sterilizing apparatus according to the embodiment.

The sterilization method according to the embodiment illustrated in FIG. 7 can be performed in the automotive sterilizing apparatuses 100A and 100B illustrated in FIG. 1 or FIG.

First, the first sensing unit 130 senses whether the driver or the passenger is present in the vehicle 200, and outputs the sensed result to the light emission control unit 120 (operation 310).

The light emission control unit 120 controls the light emitting module 110 to emit deep ultraviolet light when it is determined that the driver or the occupant is present in the vehicle through the result detected by the first sensing unit 130 step).

However, if it is determined that the driver or the passenger is not present in the interior of the vehicle through the result sensed by the first sensing unit 130, the light emission control unit 120 may determine the amount of charge of the automobile battery through the result sensed by the charge sensing unit 150 It is judged whether or not it is a critical amount (Step 330). Here, the critical amount means a charged amount of the battery in which the discharge of the battery is expected when the light emitting module unit 110 operates.

If it is determined that the charged amount of the battery is less than the critical amount, the light emission control unit 120 controls the light emitting module unit 110 to prevent the deep ultraviolet light from being emitted (operation 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 or after steps 340 through 380. Accordingly, when the amount of charge of the battery is insufficient while the light emitting module unit 110 emits deep ultraviolet light, the light emitting control unit 120 can control the light emitting operation of the light emitting module unit 110 to stop, Can be prevented.

If it is determined that the charged amount of the battery is greater than the threshold amount, the light emission control unit 120 controls the power supply unit 140 to supply the power to the light emitting module unit (operation 340). 5, when the light emitting module unit 110 is implemented as a deep ultraviolet lamp, the voltage step-up unit 190 shown in FIG. 5 boosts the power output from the power supply unit 140 and outputs the boosted result to the light emitting module unit 110. [ .

After step 340, the light emission control unit 120 determines whether the vehicle is in operation through the sensing result of the second sensing unit 180 (operation 350). If it is determined that the vehicle is in operation, the light emission control unit 120 controls the light emitting module unit 110 not to emit deep ultraviolet light (operation 320). Here, when the vehicle is turned on, it is recognized that the vehicle is in operation.

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

If it is determined that there is reserved light emission information, the light emission control unit 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 control section 120 controls the light emission module section 110 in accordance with the default light emission information (operation 380).

The automotive sterilizing apparatuses 100A and 100B according to the above-described embodiments can sterilize harmful microorganisms entering the room of the automobile 200 by using deep ultraviolet light, so that infants, infants, It can protect against germs.
