It will be described as an example, but not limited thereto, the sterilization system 1 of the present invention may be installed in various facilities or places requiring sterilization in addition to public transportation means or multi-use facilities. .

The light irradiation unit 100 may serve to irradiate sterilization light necessary for sterilization.

2 is a schematic diagram showing the configuration of a light irradiation unit according to an embodiment of the present invention.

Referring to FIG. 2 , the light irradiation unit 100 according to an embodiment of the present invention may include a light source unit 110 and a movable mirror unit 120 .

The light source unit 110 may include at least one light source, and in the embodiment of the present invention, since the case where the light irradiation unit 100 irradiates sterilization light for sterilization to the sterilization target area is described as an example, the light source unit 110 may include at least a light source for generating sterilizing light.

In the embodiment of the present invention, the light source unit 110 includes a light source such as LED or LD that generates ultraviolet rays such as UV-C having a wavelength of 100 to 280 nm as sterilizing light, for example, but in this It is not limited, and the type of light source included in the light source unit 110 may be variously changed according to the time required for sterilization or sterilization efficiency.

The movable mirror unit 120 may serve to reflect the sterilizing light generated from the light source unit 110 so that the sterilizing light generated from the light source unit 110 is irradiated to at least a part of the sterilization target area.

The position of the movable mirror unit 120 may be adjusted so that the direction in which the sterilizing light is irradiated is adjusted, and in the embodiment of the present invention, the movable mirror unit 120 is rotated in at least one direction to adjust the position. For example, but not limited thereto, the position of the movable mirror unit 120 may be adjusted by a rotational motion, a linear motion, or a combination thereof.

For example, the position of the movable mirror unit 120 may be adjusted according to the rotation direction as shown in FIGS. 3 and 4 , and the direction in which the sterilizing light is reflected is changed according to the position of the movable mirror unit 120 , so that the light irradiation unit The direction in which the sterilizing light is irradiated by (100) can be adjusted.

At this time, the dotted line in FIGS. 3 and 4 indicates the reflection direction when the movable mirror unit 120 is in the initial position as shown in FIG. 2 , and the position of the movable mirror unit 120 is adjusted as shown in FIGS. 3 and 4 . It is shown for comparison with the reflection direction in the case of

When the direction in which the sterilizing light is reflected is changed by adjusting the position of the movable mirror unit 120, even if the size of the irradiation area irradiated with the sterilizing light from the light irradiation unit 100 is smaller than the sterilization target area, the movable mirror unit 120 Because the sterilization light can be irradiated to the entire area to be sterilized by adjusting the position of As the number of light sources is reduced, power consumption or cost can be reduced, and it is advantageous for miniaturization.

In other words, in the prior art, the irradiation area of the sterilization light has a size corresponding to the sterilization target area so that the sterilization light is irradiated collectively to the entire sterilization target area, and a plurality of light sources can be arranged to form an irradiation area having a size corresponding to the sterilization target area. However, in the embodiment of the present invention, even when a single light source is used, since the sterilization light can be irradiated to the entire area to be sterilized by adjusting the position of the movable mirror unit 120, sterilization even with a relatively small number of light sources It becomes possible to easily sterilize the target area.

That is, even when the size of the irradiation area I of the sterilization light is small compared to the size of the area P to be sterilized as shown in FIG. 5 , the irradiation area I of the sterilization light is moved by adjusting the position of the movable mirror unit 120 . While the sterilization target area P is to be irradiated with the sterilization light as a whole.

In FIG. 5, the case where the irradiation area I of the sterilization light is moved linearly in one direction so that the sterilization light is irradiated as a whole to the sterilization target area P is described as an example, but this is only an example to help the understanding of the present invention. As one, but not limited thereto, the irradiation area (I) is moved in at least one direction according to the size of the sterilization target area (P) and the irradiation area (I), so that the sterilization light is irradiated as a whole to the sterilization target area (P) have.

At this time, if the size of the sterilization target area (P) is larger than the irradiation area (I), the irradiation area (I) maintains the current position for the time required to complete the sterilization of the current position, and then moves to the next position to the sterilization target area (P) The sterilization may be performed as a whole, or the irradiation area I may be repeatedly moved in at least one direction in the sterilization target area P to sterilize the entire sterilization target area P.

On the other hand, the light irradiation unit 100 may adjust the concentration of the sterilizing light according to the size of the irradiation area of the sterilizing light.

Referring to FIG. 6 , the light irradiator 100 according to another embodiment of the present invention includes a light control unit that adjusts the concentration of sterilizing light generated from the light source unit 110 together with the light source unit 110 and the movable mirror unit 120 . 130 may be further included.

The light control unit 130 adjusts the size of the sterilizing light irradiation area to prevent a part of the sterilizing light irradiation area irradiated from the light irradiating unit 100 from escaping the sterilizing target area and irradiating the sterilizing light to unnecessary areas. It can serve to prevent a decrease in the energy density of the area so that efficient sterilization is achieved.

7 and 8 are schematic diagrams illustrating a configuration of a light control unit according to an embodiment of the present invention.

7 and 8 , in the light control unit 130 according to an embodiment of the present invention, the sterilizing light L1 generated from the light source unit 110 at a first light collection degree sets a second light collection degree different from the first light concentration degree. The light condensing degree can be adjusted to be converted into the sterilizing light L2, and in the embodiment of the present invention, a case in which the first light condensing degree is lower than the second light condensing degree will be described as an example, but the present invention is not limited thereto, and the The opposite is also possible.

At this time, the high concentration of the sterilizing light means that the irradiation area of the sterilizing light generated from the light source unit 110 is relatively small. It can be understood that the energy density is increased, and in this case, the sterilization efficiency of the irradiation area of the sterilizing light can be improved.

The light control unit 130 may include a plurality of lenses 131 and 132 disposed along the propagation direction of the sterilizing light. 131) and the second lens 132 will be referred to.

The first lens 131 may be located closer to the light source 110 than the second lens 132 based on the path of the sterilizing light, and the first lens 131 and the second lens 132 have the same optical axis ( Ax).

In the embodiment of the present invention, a case in which the sterilizing light L1 having a first light concentration is converted into the sterilizing light L2 having a second light concentration higher than the first concentration by the light control unit 130 is an example. For example, the effective area A2 of the second lens 132 may be smaller than the effective area A1 of the first lens 131 , and in this case, the focus F and the second lens 132 . The focal length between the focal lengths is shorter than the focal length between the focal point F and the first lens 131 .

The effective area of the lens refers to an area that actually affects the path of the incident light among the entire area of the lens. The lens may be formed to have a size corresponding to the effective area, or to have a larger size than the effective area. can be formed.

In the above-described light control unit 130 , the sterilizing light L1 having a first condensing degree is incident to the first lens 131 substantially parallel to the optical axis Ax, and the sterilizing light emitted from the first lens 131 . is focused on the focal point F located between the first lens 131 and the second lens 132 , and is converted to have a second light concentration by the second lens 132 and is approximately on the optical axis Ax. It can be emitted in parallel.

In this case, FIG. 7 is an example of a case in which the first lens 131 and the second lens 132 are respectively formed to have diameters corresponding to the effective area, and FIG. 8 is the first lens 131 and the second lens 132 . ) has the same diameter but has different effective areas.

In addition, in the embodiment of the present invention, a case in which the shape of the lens and the shape of the effective area are the same will be described as an example, but the present invention is not limited thereto, and the shape of the lens and the shape of the effective area may be different from each other, for example, When the lens has a circular shape, the effective area may have a circular shape or a non-circular shape.

The shape of the lens or the shape of the effective area is not limited to the above-described example, and the lens and the effective area may have a circular shape, a polygonal shape, or a combination thereof.

In the embodiment of the present invention, the case in which the light control unit 130 is composed of a plurality of lenses is described as an example, but this is only an example to help the understanding of the present invention, and the present invention is not limited thereto. As reference numeral 130 , various types of optical elements that affect properties of light, such as a path of light, may be used to control the light condensing degree as well as the lens.

The control unit 200 may control the light irradiation unit 100 according to the area to be sterilized, and the control unit 200 may control at least one of the power supplied to the light source unit 110 and the position of the movable mirror unit 120 . have.

The controller 200 may determine the size of the sterilization target area and the size of the sterilizing light irradiation area, and adjust the position of the movable mirror unit 120 so that the sterilizing light is irradiated to the entire sterilizing target area.

9 to 12 are schematic views showing a sterilization target area P in which sterilization is performed by the sterilization system according to an embodiment of the present invention, and FIGS. An example of a case in which the sterilization system 1 of the present invention is installed, and FIG. 12 is an example of a case in which the sterilization system 1 of the present invention is installed in a vehicle.

9 and 10 show an example of a case in which a partial area of the wall surface of an indoor space is set as the sterilization target area P, and the control unit 200 operates according to the size of the irradiation area I and the sterilization target area P. By adjusting the position of the mirror unit 120 so that the irradiation area I of the sterilization light is moved in at least one direction as indicated by an arrow, the sterilization light can be irradiated to the entire area to be sterilized (P).

In this case, FIG. 9 is an example of a case where the sterilization target area P is formed on a single wall surface, and FIG. 10 is an example of a case where the sterilization target area P is continuously formed on two or more wall surfaces adjacent to each other.

As described above, in the sterilization system 1 of the present invention, even if the sterilization target area is changed, easy sterilization is possible by adjusting the position of the movable mirror unit 120 without rearranging the light source according to the sterilizing target area.

11 is an example of a case in which the sterilization target area P is divided into a plurality of divided areas P1 and P2 spaced apart from each other. ) may be controlled to sterilize each of the plurality of divided regions P1 and P2 by controlling at least one of the positions.

For example, since the plurality of divided areas P1 and P2 are spaced apart from each other, the control unit 200 performs sterilization of any one of the plurality of divided areas P1 and P2 by the movable mirror unit 120 . While the position of the movable mirror unit 120 is adjusted so that the reflected sterilizing light is irradiated to the other one of the plurality of divided regions P1 and P2, the light source unit 110 is turned off to irradiate the sterilizing light to unnecessary areas, thereby reducing energy waste can be prevented from occurring.

That is, since the sterilization system 1 of the present invention can share two or more sterilization target areas, the cost can be reduced compared to the case where the light sources are respectively arranged for two or more sterilization target areas.

12 is an example of a case in which the sterilization system of the present invention is installed on a roof panel of a vehicle to sterilize a vehicle interior space such as a vehicle seat. ), various sterilization target areas in the vehicle can be sterilized through control of at least one of the power supplied to and the position of the movable mirror unit 120 .

The location or location where the sterilization system 1 of the present invention is installed is not limited to the above-described example, and it is located in various locations that enable easy sterilization for public transportation means or multi-use facilities that are highly contagious by many people. can be installed.

On the other hand, as described above, when a person is present in a place where sterilization is performed by the sterilization system 1 of the present invention, since the sterilization light may have a harmful effect on the human body, sterilization is performed only when a person is not present. A human body sensor 300 for detecting a person may be included.

The human body detection unit 300 may include various types of sensors capable of detecting whether a person is present in a place where sterilization is performed, such as a photo sensor, an infrared sensor, a weight sensor, etc. When a person is present, the light source unit 110 is turned off, and when a person is not present, the light source unit 110 is turned on so that the sterilizing light is irradiated from the light irradiation unit 100 .

Although the above-described sterilization system 1 of the present invention is described as an example in which the direction in which the sterilization light is irradiated is changed by adjusting the position of the movable mirror unit 120 at a predetermined installation position, it is not limited thereto, and the present invention is not limited thereto. In the sterilization system 1 of the present invention, the direction in which the sterilization light is irradiated may be changed through the position adjustment of the light irradiation unit 100 as well as the position adjustment of the movable mirror unit 120 .

13 is a block diagram showing the configuration of a sterilization system according to another embodiment of the present invention.

Referring to FIG. 13 , the sterilization system 1 according to another embodiment of the present invention may include a light irradiation unit 100 , a control unit 200 , a human body sensing unit 300 and a driving unit 400 , and Elements having the same role as the embodiments will use the same reference numerals, and a detailed description thereof will be omitted.

In another embodiment of the present invention, the driving unit 400 may serve to adjust the position of the light irradiation unit 100 , and a movable mirror unit on the path through which the sterilization light is irradiated from the light irradiation unit 100 to the sterilization target area. If there is an obstacle that is not resolved by adjusting the position of 120, the light irradiator 100 adjusts the position by rotational motion, linear motion, or a combination thereof, so that even if there is an obstacle, the sterilizing light is sterilized in the area to be sterilized It can play a role in ensuring that it is evenly investigated.

For example, when the sterilization system 1 of the present invention is installed in a vehicle, it is difficult to sterilize the front and rear seats of the vehicle only by adjusting the position of the movable mirror unit 120 due to the seats of the vehicle. Therefore, as shown in FIG. 14 , by allowing the light irradiation unit 100 to be moved linearly by the driving unit 400 , it is possible to sterilize the front and rear seats of the vehicle.

In another embodiment of the present invention, the driving unit 400 is described as an example in which the light irradiator 100 is configured of a rail that allows the linear movement, but the present invention is not limited thereto, and the driving unit 400 is the light irradiating unit 100 . The position may be adjusted by a rotational motion, a linear motion, or a combination thereof.

At this time, in FIG. 14, when the sterilization system 1 of the present invention is installed in a vehicle, a case in which the position of the light irradiation unit 100 is adjusted by the driving unit 400 according to an obstacle is described as an example, but is not limited thereto. In addition, the sterilization system 1 of the present invention can be similarly applied to the case where it is installed not only in a vehicle, but also in the aforementioned public transportation means or multi-use facility.

Meanwhile, in the above-described embodiments, the case where only the sterilization light is irradiated from the light irradiation unit 100 is described as an example, but the present invention is not limited thereto. Any one of a plurality of different wavelengths may be generated to play a role for improving convenience, such as lighting, and in this case, the light source unit 110 may include a plurality of light sources that generate a plurality of different wavelengths. can

15 and 16 are schematic diagrams illustrating the configuration of a light source unit including a plurality of light sources emitting light of a plurality of different wavelengths according to an embodiment of the present invention.

15 and 16 , the light source unit 110 according to an embodiment of the present invention may include a plurality of light sources 111a, 111b, 111c, and 111d for emitting light of different wavelengths, In the embodiment, the plurality of light sources 111a, 111b, 111c, and 111d include a first light source 111a that emits light having a wavelength corresponding to the sterilizing light, and second to fourth light sources that emit light having a wavelength corresponding to visible light. The case including the light sources 111b, 111c, and 111d will be described as an example, but this is only an example to help the understanding of the present invention, and the present invention is not limited thereto, and the installation of the sterilization system 1 of the present invention The type of wavelength, the number or type of light sources, etc. may be variously changed according to the location or facility used.

The control unit 200 generates light from the first light source 111a when sterilization is required, and when a person is present in a space where sterilization is performed, the second to fourth light sources 111b, 111c, 111d) may be turned on.

For example, when the sterilization system 1 of the present invention is installed in a vehicle, the control unit 200 generates a sterilization light by the first light source 111a when the vehicle is not running and there is no occupant to perform sterilization. When the vehicle is in a driving state, at least one of the second to fourth light sources 111b, 111c, and 111d is turned on to provide lighting for a reading lamp.

In this case, each of the second to fourth light sources 111b, 111c, and 111d may generate red, green, and blue light, respectively, and the light source unit 110 is generated from the second to fourth light sources 111b, 111c, and 111d. An optical unit 112 for synthesizing light generated from the plurality of light sources 111a, 111b, 111c, and 111d may be included so that light of various colors is generated according to a combination of the used lights.

For example, the optical unit 112 may be made of a prism as shown in FIG. 15 to synthesize light generated from at least one of the first to fourth light sources 111a, 111b, 111c, and 111d, as shown in FIG. When a plurality of mirrors 112a, 112b, 112c, and 112d are used as the optical unit 112, each of the plurality of mirrors 112a, 112b, 112c, 112d is one of the plurality of light sources 111a, 111b, 111c, and 111d. Light emitted from one may be reflected and part of the other may be transmitted to produce synthetic light.

In this case, FIGS. 15 and 16 show that the second to fourth light sources 111b, 111c, and 111d generate light having a wavelength corresponding to visible light among the first to fourth light sources 111a, 111b, 111c, and 111d. As an example of a case of synthesizing light to be used, the present invention is not limited thereto, and when sterilizing light is generated, the second to fourth light sources 111b, 111c, and 111d may be turned off and the first light source 111a may be turned on. .

In the above-described embodiment, a case in which the light source unit 110 generates light having a wavelength corresponding to the sterilizing light and a light source from which light having a wavelength corresponding to visible light is generated will be described as an example, but the present invention is limited thereto. It may include a light source that generates light for various purposes, such as a light source that generates light having a wavelength corresponding to infrared light for sleep induction or skin care.

In addition, in the above-described embodiment, when the sterilization system 1 of the present invention is installed in a vehicle, a case in which any one of various wavelengths of light is generated is described as an example, but the present invention is not limited thereto. (1) may be similarly applied when it is installed in public transport or in a multi-use facility.

On the other hand, the sterilization system 1 of the present invention has been described as an example in which sterilization is performed by irradiating sterilization light when there is no person in the space where the sterilization light is irradiated, but the present invention is not limited thereto. In order to recognize the progress of sterilization from the outside of the space, light of a predetermined color can be irradiated to the sterilization target area before and after sterilization. In a case in which light of different colors is irradiated in a method of irradiating the sterilizing light, that is, adjusting the position of the movable mirror unit 120 so that the light is irradiated to the entire area to be sterilized so that the irradiated area of light is moved in at least one direction. Let me explain with an example.

For example, when it is possible to check the inside through window glass from the outside such as in a vehicle, office, store, etc., the light of the first color is irradiated to the area to be sterilized before sterilization, and after sterilization, a product different from the first color is irradiated. By irradiating two colors of light, it is possible to easily recognize the sterilization process from the outside, while improving the aesthetics to prevent the sterilization from being reflected as a negative image to users.

In the embodiment of the present invention, a case in which the first color is red and the second color is blue will be described as an example, but this is only an example to help the understanding of the present invention, and is not limited thereto. The color and the second color are various among the light sources 111b, 111c, and 111d from which light of a wavelength corresponding to visible light is generated among the plurality of light sources 111a, 111b, 111c, and 111d of FIGS. 15 and 16 described above. It can have various colors by combination.

In addition, the sterilization system 1 of the present invention is such that when a person is detected in a space where sterilization has already been completed, light of a color indicating that sterilization has been completed is irradiated to the sterilization target area in a similar irradiation method as the sterilization light described above.
