Abstract

A mobile disinfector using UV LEDs can include: a case forming an exterior structure of the disinfector; a cover including two parts coupled to respective sides of the case and including openings formed on the cover; and LED units exposed to outside through the openings formed on the cover. Since the cover is coupled to the case such that an angle between the cover and the case is adjusted, an irradiation angle of light emitted to the outside from the LED units is controlled.

Claims

1. A mobile disinfector using ultraviolet (UV) light emitting diodes (LEDs), comprising:

a case forming an exterior structure of the mobile disinfector;

a cover including two parts coupled to respective sides of the case with openings formed on the cover; and

a plurality of LED units disposed on the cover and exposed to outside through the openings formed on the cover,

wherein the cover is coupled to the case such that an angle between the cover and case is adjusted and an irradiation angle of light emitted to the outside from the LED units is controlled.

2. The mobile disinfector of claim 1, wherein the case is formed in a rectangular parallelepiped shape of which one side is longer than another side.

3. The mobile disinfector of claim 1, wherein the LED units provide UV light at a wavelength of 100 nm to 280 nm.

4. The mobile disinfector of claim 1, wherein the cover comprises a material formed on a front surface of the cover, the material increasing a reflectance of UV light irradiated from the LED units.

5. The mobile disinfector of claim 4, wherein the material to increase the reflectance comprises aluminum (Al).

6. The mobile disinfector of claim 1, wherein the two parts of the cover have a door-shaped structure which hinged to the respective sides of the case to open and close with respect to a front surface of the case.

7. The mobile disinfector of claim 1, wherein the two parts of the cover comprises:

a left cover coupled to an edge of a left sidewall of the case to extend upward from the edge of the left sidewall when opened; and

a right cover coupled to an edge of a right sidewall of the case to extend upward from the edge of the right sidewall when opened.

8. The mobile disinfector of claim 7, wherein at least one of the left cover or the right cover is coupled to the respective edges of the left or right sidewalls to move up and down.

9. The mobile disinfector of claim 1, wherein each of the LED units are disposed on a rear surface of the cover, and have a light emitting surface exposed through the corresponding opening.

10. A mobile disinfector using ultraviolet (UV) light emitting diodes (LEDs), comprising:

a case forming an exterior structure of the disinfector and having a first group of openings formed on the case;

a cover including two parts coupled to respective sides of the case and having a second group of openings formed on the cover; and

LED units disposed on the cover exposed to outside through the second group of openings of the cover and LED units disposed on the case exposed to the outside through the first group of openings of the case,

wherein the cover is coupled to respective sides of the case to provide an adjustable angle between the cover and the case and control an irradiation angle of light emitted to the outside from the LED units disposed on the cover through the second group of openings.

11. The mobile disinfector of claim 10, wherein at least one of the LED units disposed on the cover or the case provide UV light at a wavelength of 100 nm to 280 nm.

12. The mobile disinfector of claim 10, wherein the two parts of the cover have a door-shaped structure hinged to the respective sidewalls of the case to open and close with respect to a front surface of the case.

13. The mobile disinfector of claim 10, wherein the two parts of the cover comprises:

a left cover coupled to an edge of a left sidewall of the case to extend upward from the edge of the left sidewall when opened; and

a right cover coupled to an edge of a right sidewall of the case to extend upward from the edge of the right sidewall when opened.

14. The mobile disinfector of claim 13, wherein at least one of the left cover or the right cover is coupled to the respective edges of the left or right sidewalls to move up and down.

15. The mobile disinfector of claim 13, wherein the left cover and the right cover are fixed to a front surface of the case such that the LED units disposed on the cover and exposed through the first and second group of openings are fixed in a same horizontal direction.

16. A method of disinfecting an object, comprising:

providing a portable disinfector having a portable case and UV LEDs in the portable case to emit UV light for disinfecting the object; and

providing a moveable cover coupled to the portable case to allow a user control of an angle of irradiation of the UV light emitted from UV LEDs disposed on the cover towards the object in a configuration in which the emitted UV light is transmitted through openings formed on the cover.

17. The method of claim 16, comprising:

configuring the portable disinfector to allow for adjusting two parts of the moveable cover coupled to respective sidewalls of the case to independently adjust each part of the moveable cover to independently control the angle of irradiation of light emitted from respective UV LEDs disposed on the two parts of the moveable cover.

18. The method of claim 17, wherein directions of irradiation of light emitted from the UV LEDs disposed on the two parts of the cover are different from each other.

19. The method of claim 17, comprising providing an irradiation of light emitted from UV LEDs fixedly disposed on a front surface of the mobile disinfector at a direction different from directions of the irradiation of light emitted from UV LEDs disposed on the two parts of the cover.

20. The method of claim 16, wherein the emitted light from the UV LEDs are at a wavelength of 100 nm to 280 nm.
