Here, the electronic device 10 may be a mobile device such as a smartphone or a tablet PC.

The inner surface of the housing 110 may be formed of a material that reflects germicidal ultraviolet rays or coated with a material that reflects germicidal ultraviolet rays. Therefore, the wireless charging device 100 can improve the sterilization efficiency of the electronic device 10 .

The wireless charging unit 120 wirelessly charges the electronic device 10 . The wireless charger 120 is disposed on one surface of the housing 110 . When the wireless charging unit 120 is in contact with or close to the electronic device 10, wireless charging is performed. Therefore, the wireless charging unit 120 is disposed to be in contact with the electronic device 10 . For example, the wireless charging unit 120 may be disposed on the lower surface of the housing 110 as shown in FIG. 1 . For example, the wireless charger 120 may charge the electronic device 10 by transmitting power to the electronic device 10 in a magnetic induction method.

When the electronic device 10 is inserted into the housing 110 and placed on the lower surface of the housing 110, the wireless charging unit 120 starts wirelessly charging the electronic device 10. In addition, when the electronic device 10 is removed from the wireless charging unit 120, wireless charging is stopped.

The sterilization unit 130 sterilizes the electronic device 10 by irradiating the electronic device 10 with sterilizing ultraviolet rays. Although not shown, the sterilization unit 130 includes a light source unit and a control unit. The light source unit includes at least one germicidal light source that emits germicidal ultraviolet light. In addition, the control unit supplies power to the light source unit or stops supplying power. When the control unit supplies power to the light source unit, the light source unit emits germicidal ultraviolet rays. In addition, when the control unit stops supplying power to the light source unit, the light source unit stops emitting germicidal ultraviolet light. For example, the control unit may be a substrate on which a wiring for supplying power to a sterilizing light source is formed.

The light source unit may include a light emitting diode that emits ultraviolet rays.

For example, the light emitting diode may be a light emitting diode having a structure shown in FIG. 3 .

The first contact region R1 may be disposed around the mesa M along the periphery of the first conductivity type semiconductor layer 62 . Also, the second contact region R2 may be at least partially surrounded by the mesa M. Through this, current can move in the outer and center portions of the light emitting diode, so that the current can be effectively distributed, so that the forward voltage can be reduced.

The second electrode 67 is disposed on the second conductivity type semiconductor layer 64 and can be electrically connected to the second conductivity type semiconductor layer 64 . The second electrode 67 may include a reflective metal layer 65 formed on the second conductive semiconductor layer 64 and a barrier metal layer 66 formed to cover top and side surfaces of the reflective metal layer 66 .

However, the structure of the light emitting diode is not limited to the structures shown in FIGS. 3 and 4 . The light emitting diode can be of any type and structure as long as it emits germicidal ultraviolet light.

The sterilizing ultraviolet rays emitted from the sterilization unit 130 may be ultraviolet rays of any wavelength capable of sterilizing the electronic device 10 . For example, the germicidal ultraviolet light may be ultraviolet light in a wavelength range of 200 nm to 290 nm, which is UVC. However, germicidal ultraviolet rays may also be ultraviolet rays of UVA (320 nm to 400 nm) or UVB (290 nm to 320 nm).

Here, the front of the electronic device 10 is a surface facing the upper surface of the housing 110 where the first sterilization unit 530 is disposed in the electronic device 10 .

The second sterilization unit 540 is disposed on the lower surface of the housing 110 . The second sterilization unit 540 sterilizes the rear surface of the electronic device 10 when the electronic device 10 is in a state of being spaced apart from the wireless charging unit 120 .

The wireless charging device 500 according to the present embodiment can sterilize not only the front side of the electronic device 10 but also the rear side by the separation unit 520, the first sterilization unit 530, and the second sterilization unit 540. .

In addition, if the inner surface of the housing 110 reflects sterilizing ultraviolet light, the sterilizing ultraviolet light emitted from at least one of the first sterilizing unit 530 and the second sterilizing unit 540 is reflected by the inner surface of the housing 110. It can be irradiated to the side of the electronic device (10).

In this embodiment, when the electronic device 10 contacts the wireless charging unit 120, the first sterilization unit 530 operates, and when the electronic device 10 is spaced apart from the wireless charging unit 120, the second sterilization unit ( 540) is described as operating. However, if the wireless charging device 500 has an input that can separately operate the first sterilization unit 530 or has pre-stored settings, the first sterilization unit 530 also includes the electronic device 10 and the wireless charging unit 120.

The sterilization wavelength setting unit 1710 receives the travel time and calculates the wavelength range of sterilization ultraviolet rays for sterilization of electronic devices. That is, the sterilization wavelength setting unit 1710 calculates the wavelength range of sterilization ultraviolet rays for the electronic device to reach a preset sterilization power during the driving time.

The sterilization wavelength setting unit 1710 generates a sterilization wavelength setting signal including data on the calculated wavelength range of the sterilization ultraviolet light. The sterilization wavelength setting unit 1710 transmits the sterilization wavelength setting signal to the control unit 1630.

The control unit 1630 supplies power to a light source unit that emits sterilizing ultraviolet light in a wavelength band corresponding to a sterilization wavelength setting signal among the first light source unit 1520 to the n-th light source unit 1530 .

The wireless charging devices 1800 and 1900 according to the embodiments of FIGS. 24 and 25 calculate the user's driving time and select the light amount or wavelength range of the sterilizing ultraviolet light. Such a wireless charging device 1900 can sufficiently sterilize electronic devices according to the user's driving time.

The wireless charging device having a sterilization function according to an embodiment of the present invention can automatically sterilize an electronic device when it is being charged. In addition, the wireless charging device may allow sterilization to be performed at a place where electronic devices are placed for charging. In addition, the wireless charging device can be automatically charged and sterilized according to the charging time or the user's driving time. Therefore, the wireless charging device according to an embodiment of the present invention automatically sterilizes the electronic device even if the user does not take action to sterilize the electronic device, enabling easy hygiene management of the electronic device.
