Abstract

A sanitizing apparatus in a flexible configuration that uses ultraviolet (UV) radiation emitted from light emitting diodes (LEDs) may be folded or rolled for storage and transport. A piecewise flexible sanitizing apparatus may be formed with hinged or otherwise rotationally joined panels, and provides the ability to sanitize a variety of objects beneath enclosure panels. A continuous flexible sanitizing apparatus with an enclosure panel formed of flexible material may be folded or rolled and may be used with a support structure to treat taller objects.

Claims

1. A sanitizing apparatus with a flexible configuration comprising:

a two-dimensional array of ultraviolet (UV) light emitting diodes (LEDs) mounted in a flexible enclosure panel, wherein the LEDs face an open side of the flexible enclosure panel and the flexible enclosure panel is continuously flexible and pliable to allow the panel to conform to objects and be rolled or folded for storage and transport;

a folding support structure for the flexible enclosure panel, wherein the folding support structure comprises a folding frame with upper members for supporting the flexible enclosure panel and leg members for supporting the upper members;

a power source for providing electrical energy to operate the UV LEDs;

an interlock means operable to allow power to the UV LEDs when the panels are in the operational position;

a switch means for powering the UV LEDs; and

a timing circuit operating in response to activation of the switch means to operate the UV LEDs for a predetermined sanitizing period.

2. The sanitizing apparatus of claim 1, wherein the UV LEDs emit UVC radiation.

3. The sanitizing apparatus of claim 1, wherein the UV LEDs emit sanitizing radiation at or below a wavelength of approximately 254 nm.

4. The sanitizing apparatus of claim 1, wherein the power source is selected from a group consisting of fuel cells, batteries, AC power, AC power converted to DC power, and DC power.

5. The sanitizing apparatus of claim 4, wherein the power source is DC power provided by a computer port.

6. The sanitizing apparatus of claim 1, wherein control circuitry provides both the interlock means and the timing circuit.

7. The sanitizing apparatus of claim 6, wherein the timing circuit further comprises at least one indicator whereby current operational status of the sanitizing apparatus is conveyed.

8. The sanitizing apparatus of claim 1, further comprising a control box for housing the power source, interlock means, switch means, and timing circuit.

9. The sanitizing apparatus of claim 6 wherein the flexible enclosure panel is rolled inward to the control box for transportation and storage of the apparatus.

10. The sanitizing apparatus of claim 1, wherein the support structure comprises folding walls.

11. The sanitizing apparatus of claim 1, wherein the support structure further comprises opaque, flexible side-walls.

12. The sanitizing apparatus of claim 1, wherein the support structure further comprises rigid side-walls.

13. The sanitizing apparatus of claim 12, wherein the rigid side-walls are formed from a material selected from the group consisting of aluminum and UV resistant plastic.

14. The sanitizing apparatus of claim 1 further comprising means for attaching or securing the panel on the folding support structure.

15. The sanitizing apparatus of claim 14, wherein, wherein the interlock means is configured to allow power to the UV LEDs when the panels are attached or secured to the folding support structure.

16. The sanitizing apparatus of claim 1, wherein the upper members and the leg members are attached in a jointed manner.
