Technical Field

The present invention relates to a sterilizable lamp assembly for a vehicle and a sterilization method using the same, which can selectively or simultaneously perform indoor lighting and a sterilization function of the vehicle.

Background

The interior of the vehicle is provided with various illumination lamps to illuminate the interior when the surrounding environment is dark.

Furthermore, in addition to the lighting for identifying objects, the interior of the vehicle is also provided with an atmosphere lamp for atmosphere lighting of the interior.

Such a light or ambience lamp simply illuminates the light used for indoor lighting or ambience lighting when power is supplied thereto.

Meanwhile, various devices installed in a vehicle interior are easily exposed to bacteria that are transmitted by contact of passengers or received from the outside thereof through air or the like. For example, microorganisms tend to proliferate among door inside handles operated by passengers when the passengers get on or off the vehicle, steering wheels operated by drivers when operated, seats occupied by passengers, and the like.

For this reason, conventionally, bacteria are removed by spraying or applying a disinfectant or the like, respectively. However, disinfection of disinfectants is time consuming and therefore cumbersome. Further, since the effect disappears with time, there is a problem that the sterilization operation needs to be repeated.

In recent years, vehicle sharing services are increasing, and in such vehicle sharing services, the number of passengers using one vehicle is increasing, thereby increasing the degree of contamination of the vehicle interior with bacteria. However, since the maintenance of the interior of the vehicle is not controlled so much, users of the vehicle sharing service are easily exposed to the environment of bacterial contamination.

The information included in the background section of the invention is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any way suggestion that this information forms the prior art already known to a person skilled in the art.

The sterilizable light assembly of the vehicle further includes a controller for turning on the sterilization light; and an ICU for outputting an on signal of the sterilizing lamp to the controller when it is detected that the passenger is not seated in the vehicle by a passenger detection sensor that detects whether the passenger is seated in the interior of the vehicle.

The sterilizing lamp is installed in the handle housing of the door inner side handle to illuminate the door inner side handle.

The sanitizing light is mounted within a blow duct configured to blow air into the interior of the vehicle.

The sanitizing light is mounted at a bumper of the vehicle to illuminate a mobile phone holder, wherein the mobile phone is configured to be held for wireless charging.

The germicidal lamp is mounted at the headliner at the interior of the vehicle to illuminate the interior of the vehicle.

An ambience lamp for ambience lighting an interior of the vehicle is mounted adjacent to the disinfection lamp.

A sterilization method using a sterilizable lamp assembly of a vehicle includes, in a sterilization method for sterilizing an interior of a vehicle by using at least one sterilization lamp installed in the interior of the vehicle and irradiating light of a sterilizable wavelength to the interior of the vehicle, determining whether a passenger has been seated in the interior of the vehicle, and sterilizing the interior of the vehicle by turning on the sterilization lamp when it is determined that the passenger is not seated in the vehicle.

The sterilization method using a sterilizable light assembly of a vehicle further includes inputting a sensor value input from a passenger detection sensor installed in the vehicle to the ICU before determining whether a passenger has been seated in the vehicle.

The sterilizing includes starting sterilizing lighting when it is determined by the ICU that the passenger is not seated in the vehicle, i.e., outputting an on signal of a sterilizing lamp to the controller; and turning on the sterilizing lamp by supplying power to the sterilizing lamp when an on signal of the sterilizing lamp is received from the ICU through the controller.

When it is determined whether the predetermined sterilization time is exceeded, when it is determined that the time for which the sterilization lamp has been turned on does not exceed the predetermined sterilization time, the determination of whether the predetermined sterilization time is exceeded is repeatedly performed to maintain the state in which the sterilization lamp has been turned on.

When it is determined that the passenger has been seated in the vehicle, a lighting mode is performed in which the interior of the vehicle is ambience-illuminated by an ambience lamp mounted adjacent to the sterilizing lamp when it is determined that the passenger has been seated in the vehicle.

Detailed Description

Reference will now be made in detail to the various embodiments of the invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments thereof, it will be understood that the description is not intended to limit the invention(s) to those exemplary embodiments. On the other hand, the invention(s) are intended to cover not only the exemplary embodiments of the invention, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.

Hereinafter, a sterilizable lamp assembly for a vehicle and a sterilization method using the same according to exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The sterilizable lamp assembly of a vehicle according to an exemplary embodiment of the present invention includes at least one sterilization lamp 22, the at least one sterilization lamp 22 being installed in a room of the vehicle and adapted to irradiate light of a sterilizable wavelength into an interior of the vehicle, and the sterilization lamp 22 being illuminated when a passenger is not seated in the vehicle.

The sterilizing lamp 22 is installed in a room material of the vehicle to illuminate the interior of the vehicle for sterilization.

As shown in fig. 1, 2 and 3, an example in which the sterilizing lamp 22 is installed at the door inner side handle 12 installed at the door inner trim 11 of the door 10 to be operated by a passenger will be described in detail. Since the door inside handle 12 frequently comes into contact with the passenger's hand, bacteria are easily generated. Therefore, the sterilizing lamp 22 can be made to illuminate the door inner side handle 12 to sterilize it.

An opening 13a is formed in the handle housing 13 of the door inner side handle 12 so that light irradiated from the sterilizing lamp 22 can pass therethrough.

In the interior material (i.e., the handle housing 13), an outer cover 26 is mounted to cover the opening 13a, and an inner cover 27 fastened to the outer cover 26 to form a space therein is mounted. The outer cover 26 is made of a transparent material so that light can pass through.

The sterilizing lamp 22 is installed in a space formed by the outer cap 26 and the inner cap 27 inside the handle housing 13.

The sterilizing lamp 22 is a lamp for irradiating light of a sterilizable wavelength, and at least one sterilizing lamp 22 is installed.

The sterilizing lamp 22 is a Ultraviolet (UV) light emitting diode (UV LED) that irradiates UV, particularly UV-C LED that irradiates UV (UV-C) of 200nm to 280nm wavelength having an excellent effect on sterilization. The UV-C LED is smaller than a mercury lamp, which is generally used as an ultraviolet lamp, and does not contain mercury, thus being environmentally friendly, safe, and durable. Therefore, when the sterilizing lamp 22 is turned on, the area to which the light (ultraviolet rays) irradiated by the sterilizing lamp 22 reaches is sterilized.

In addition to the sterilizing lamp 22, the interior of the handle housing 13 may be provided with another lamp for illuminating the interior of the vehicle. For example, a general lamp for brightly illuminating the interior of the vehicle to recognize an object, or an atmosphere lamp 21 for atmosphere lighting that does not brighten a wide area but softly illuminates the interior of the room may be provided, thereby enhancing the interior effect.

The ordinary lamp and the atmosphere lamp 21 are illuminated in a state where the passenger has been seated in the vehicle, but are preferably illuminated in a state where the passenger is not seated because the sterilamp 22 irradiates ultraviolet rays.

The atmosphere lamp 21 is installed adjacent to the outer cover 26 to illuminate the room through the guide plate 23, and the guide plate 23 serves to diffuse light for uniform illumination. The light irradiated from the atmosphere lamp 21 is diffused while passing through the guide plate 23 to exert the effect of surface light emission, thereby realizing the atmosphere lighting effect.

Meanwhile, a diffusion plate 24 for diffusing the ultraviolet rays irradiated from the sterilizing lamps 22 is installed so that the ultraviolet rays irradiated from the sterilizing lamps 22 can be uniformly illuminated without being illuminated by concentrating any one point. When the sterilizing lamp 22 illuminates one side surface of the diffusion plate 24, the ultraviolet rays are diffused and illuminated inside the diffusion plate 24.

However, if necessary, only any one of the guide plate 23 and the diffusion plate 24 may be installed to diffuse the light irradiated from the sterilizing lamp 22 and the atmosphere lamp 21, respectively.

Meanwhile, the diffusion plate 24 is formed with a reflection surface 24a so that the light irradiated from the sterilizing lamp 22 can be efficiently irradiated to the illumination area. The reflection surface 24a is formed on a surface opposite to the surface facing the vehicle interior (i.e., a surface not facing the vehicle interior). The reflecting surface 24a reflects the light irradiated from the sterilamp 22 to the inside of the vehicle. A reflection surface 24a formed in the form of an inclined surface is repeatedly formed on the diffusion plate 24.

Meanwhile, since ultraviolet rays cannot be sufficiently reflected only by the reflection surface 24a, chromium (Cr) is applied to the reflection surface 24a to form the reflection layer 25. The reflective layer 25 is formed on the reflective surface 24a, and the ultraviolet rays irradiated from the sterilizing lamp 22 are totally reflected, and more ultraviolet rays are irradiated to the inside of the vehicle, thereby improving the sterilizing effect.

The sterilizing lamp 22 detects whether a passenger has got on the vehicle so that the passenger is not exposed to ultraviolet rays, and turns on the sterilizing lamp 22 only when the passenger has not got on the vehicle (e.g., immediately after the passenger gets off the vehicle). Since ultraviolet light is known to be harmful, the hazard lamps 22 can be turned on only when a passenger is not boarding the vehicle.

To this end, the sterilizable light assembly of the vehicle may include a passenger detection sensor 33 for detecting whether a passenger has got on the vehicle; a controller 31 for supplying power to the sterilizing lamp 22; and an integrated central controller unit (ICU)32 for receiving an output signal of the passenger detection sensor 33 to transfer whether a passenger has got on the vehicle to the controller 33.

The passenger detection sensor 33 is installed inside the vehicle to determine whether a passenger has been seated in the vehicle. For example, a sensor is installed to determine whether an airbag is operated at the time of a collision by determining a load acting on a seat, or to detect whether a door is opened when a passenger has got on the vehicle to prevent an object from approaching the rear side of the vehicle, and the sensor may be used.

The ICU32 determines whether a passenger has boarding the vehicle from the output signal of the passenger detection sensor 33, and outputs an on signal of the hazard lamps 22 to the controller 31 when the passenger is not boarding the vehicle. Since the ICU32 is an Electronic Control Unit (ECU) that integrally controls the length of the vehicle body, the ICU32 receives a signal of the passenger detecting sensor 33 and controls the controller 31 to turn on or off the sterilizing lamp 22. The ICU32 receives output signals from the passenger detection sensors 33 immediately after the passenger disembarks to determine whether the passenger has disembarked.

The controller 31 supplies power to the sterilizing lamp 22 to turn on the sterilizing lamp 22 or turns off the power applied to the sterilizing lamp 22 to turn off the sterilizing lamp 22 according to the instruction of the ICU 32.

According to the present configuration, when it is determined that a passenger is not boarding, the sterilizing lamp 22 is turned on to sterilize the vehicle interior (i.e., the door inner side handle 12).

Fig. 4 is a diagram showing a configuration in which the sterilizing lamp 22 is installed in the blow duct 41. The air blowing duct 41 is connected and mounted to an indoor material of the vehicle, such as an instrument panel, and becomes a passage for supplying air conditioned by heating or cooling to the interior of the vehicle. A grill 42 is provided at an end of the air blowing duct 41 to adjust whether air is blown and a blowing direction.

In the air blowing duct 41, bacteria increase inside the air blowing duct 41, the evaporator, and the like, and the bacteria flow into the room together with the wind at the time of air blowing.

To prevent this, a sterilizing lamp 22 may be installed at the blowing duct 41 to sterilize bacteria present in the air passing through the blowing duct 41.

Fig. 5 is a diagram showing an example in which the sterilizing lamp 22 is installed at the cushion pad 51 to sterilize and illuminate the mobile phone holder 53.

Inside the vehicle, a mobile phone holder 53 for holding a passenger's mobile phone 54 or allowing wireless charging while holding is formed at the console 52 or the like. When the passenger carries and frequently operates the mobile phone 54 by hand, the mobile phone proliferates various microorganisms. Accordingly, the sterilamp 22 is installed at the bumper 51, which is one of indoor materials of the vehicle, and illuminates the mobile phone holder 53.

When the mobile phone holder 53 has the wireless charging function, the mobile phone holder 53 detects a state in which the mobile phone 54 has been held and then starts charging. Therefore, in the example where the sterilamp 22 has been installed to illuminate the mobile phone holder 53, the sterilamp 22 is turned on by linking with the start of wireless charging.

Fig. 6 is a diagram showing a configuration in which the sterilamp 22 has been installed in the headliner 61 inside the vehicle.

The sterilizing lamp 22 is installed at the headliner 61, and irradiates ultraviolet rays to the interior of the vehicle when the sterilizing lamp 22 is turned on, thereby sterilizing the interior of the vehicle.

The headliner 61 is provided with a general lamp for illuminating the vehicle interior when the door is opened or by the operation of a passenger, or an atmosphere lamp for atmosphere illumination, and further, the sterilizing lamp 22 may be installed so as to sterilize the vehicle interior.

Meanwhile, fig. 7 is a diagram illustrating a sterilization method using a sterilizable lamp assembly of a vehicle according to an exemplary embodiment of the present invention.

The sterilization method according to the exemplary embodiment of the present invention is implemented by using the above-described sterilizable lamp assembly of the vehicle.

The sensor value input step S110 is a step in which the ICU32 receives a sensor value from the passenger detection sensor 33 mounted in the vehicle. Since ultraviolet rays for sterilization can be irradiated while the passenger is not boarding the ICU32, the ICU32 receives a sensor value from the passenger detection sensor 33 to determine whether the passenger is on the vehicle.

The input sensor value S110 is a sensor value input to the ICU32 from the passenger detection sensor 33 mounted in the vehicle. Since ultraviolet rays for sterilization may be irradiated in a state where a passenger is not seated in the vehicle, the ICU32 receives a sensor value from the passenger detection sensor 33 to determine whether the passenger has been seated in the vehicle.

It is determined whether the passenger has got on the vehicle S120 to determine whether the passenger has been riding in the vehicle. The ICU32 determines whether the passenger has got on the vehicle based on the value input from the passenger detection sensor 33. Any one of the lighting atmosphere S130 and the sterilization S140, which will be described later, may be selectively performed according to whether the passenger has been seated in the vehicle.

For example, the step S120 of determining whether the passenger has got on the vehicle may be performed immediately after the passenger gets off the vehicle.

When it is determined that the passenger has got on the vehicle, the lighting atmosphere S130 lights the interior of the vehicle by the atmosphere of the atmosphere lamp 21 installed adjacent to the sterilizing lamp 22. The sterilization by ultraviolet rays may be harmful when a passenger is present, so that the atmosphere lamp 21 is turned on to atmosphere-illuminate the inside in a state where the sterilization lamp 22 has been turned off when the passenger gets on the vehicle.

The lighting atmosphere S130 may include starting atmosphere lighting S131, that is, outputting a turn-on signal of the atmosphere lamp 21 to the controller 31 when it is determined by the ICU32 that a passenger has been seated in the vehicle, and turning on the atmosphere lamp S132, that is, turning on the atmosphere lamp 21 by supplying power to the atmosphere lamp 21, when the turn-on signal of the atmosphere lamp 21 is received from the ICU32 by the controller 31.

After the lighting atmosphere S130 has been performed, it returns to the first step of inputting the sensor value S110 or determining whether the passenger has got on the vehicle S120 to be repeatedly performed when the passenger gets on the vehicle.

When it is determined that the passenger is not seated in the vehicle S120 at the time of determining whether the passenger has got on the vehicle, the sterilization S140 is performed to sterilize the interior of the vehicle by turning on the sterilizing lamp 22.

The sterilizing S140 may include starting the sterilizing lighting S141, i.e., outputting an on signal of the sterilizing lamp 22 to the controller 31 when it is determined by the ICU32 that the passenger is not getting on the vehicle, and turning on the sterilizing lamp, i.e., supplying power to the sterilizing lamp 22 to turn on the sterilizing lamp 22 when the on signal of the sterilizing lamp 22 is received from the ICU32 by the controller 31.

After the ICU32 determines that the passenger has been seated in the interior of the vehicle, the start sterilizing lighting S141 outputs an on signal of the sterilizing lamp 22 to the controller 31 to supply power to the sterilizing lamp 22 to turn on the sterilizing lamp 22.

The sterilizing lamp S142 is turned on to turn on the sterilizing lamp 22 so that ultraviolet rays are irradiated to a portion to be sterilized. When the controller 31 supplies power to the sterilizing lamp 22, the sterilizing lamp 22 is turned on to irradiate ultraviolet rays to the interior of the vehicle. When ultraviolet rays are irradiated, bacteria exposed to the ultraviolet rays are sterilized, thereby improving the cleanliness of the interior of the vehicle.

When a plurality of passengers use a single vehicle (for example, vehicle sharing service), it is difficult to maintain the cleanliness of the vehicle, but it is possible to improve the cleanliness only by sterilizing the interior of the vehicle using the sterilizing lamp 22.

It is determined whether the sterilizing time S150 has exceeded the sterilizing time to determine whether the time the sterilizing lamp 22 has been turned on has exceeded a predetermined sterilizing time, thereby turning off the sterilizing lamp 22. The ICU32 measures the time that the germicidal lamp 22 has been on to determine if the on time of the germicidal lamp 22 has exceeded a predetermined disinfection time, from the time that the germicidal lamp 22 has been on to the time that the germicidal lamp 22 can be turned off.

The sterilizing lamp 22 irradiates ultraviolet rays so that the sterilizing lamp 22 is turned on only for a predetermined period of time.

The sterilization using the sterilizing lamp 22 is enough to turn on the sterilizing lamp 22 for a predetermined period of time and substantially no additional sterilizing effect even when more ultraviolet rays are irradiated, so that the sterilizing lamp is turned on for a predetermined period of time, i.e., only for a predetermined sterilizing time.

However, the sterilizing effect is only obtained when the sterilizing lamp 22 is turned on for at least a predetermined sterilizing time, so that the sterilizing lamp 22 is continuously turned on for the predetermined sterilizing time when the turn-on time of the sterilizing lamp 22 is less than the predetermined sterilizing time.

When it is determined that the sterilizing lamp 22 has been turned off for a predetermined period of time at the time of turning off the sterilizing lamp S160, the controller blocks power applied to the sterilizing lamp 22, thereby turning off the sterilizing lamp 22.
