Abstract

UV hard-surface disinfection system that is able to disinfect the hard surfaces in a room, while minimizing missed areas due to shadows by providing multiple UV light towers that can be placed in several areas of a room such that shadowed areas are eliminated and that can be transported by a cart that is low to the ground such that the towers may be loaded and unloaded easily by a single operator. The system is able to be controlled remotely, such that during activation of the system, no operator is present, and to automatically cut power to all towers in the event that a person enters the room.

Claims

1. A disinfection system comprising:

at least two independently placeable light towers, each of said at least two light towers including;

at least one ultraviolet light source;

a communications module capable of sending and receiving data from at least the communication module of the other light tower;

a base assembly supporting the at least one ultraviolet light source and including;

a power supply for the at least one ultraviolet light source;

a mobility mechanism allowing the base assembly to be moved across a floor independently of the other base assemblies;

wherein all of the at least two light towers are capable of being controlled remotely from a single controller.

2. The disinfection system of claim 1 further comprising a safety feature capable of shutting off each of the at least two independently placeable light towers if movement is detected.

3. The disinfection system of claim 2 wherein said safety feature comprises a motion sensor.

4. The disinfection system of claim 2 wherein said safety feature comprises a shut down signal sent by one of said communication modules to each of the other of said communication modules if motion is sensed.

5. The disinfection system of claim 1 further comprising a controller in remote communication with each of the communication modules and capable of controlling each of the at least two independently placeable light towers simultaneously.

6. The disinfection system of claim 1 wherein the mobility mechanism comprises a set of wheels.

7. The disinfection system of claim 1 wherein said safety feature comprises a shutdown signal sent from said communication module to said controller and relayed from said controller to the other communication modules of the at least two independently placeable light towers.

8. The disinfection system of claim 1 wherein at least one of the independently placeable light towers comprises a fluence sensor.

9. The disinfection system of claim 1 wherein at least one of the independently placeable light towers comprises a protective sleeve.

10. The disinfection system of claim 1 wherein at least one of the independently placeable light towers comprises an audible element.

11. The disinfection system of claim 1 wherein the controller comprises a user interface.

12. The disinfection system of claim 1 further comprising a controller for remotely operating each of the at least two independently placeable light towers.

13. A method for disinfecting an enclosed space comprising:

establishing data communication between a controller and at least two independently placeable ultraviolet light towers present in the enclosed space;

energizing ultraviolet lights on the at least two light towers using signals from a single controller;

scanning the space for movement using a safety feature associated with said at least two independently placeable ultraviolet light towers;

shutting down said at least two ultraviolet light towers automatically if said safety feature detects movement in said space.

14. The method of claim 13 wherein the step of establishing data communication between a controller and at least two independently placeable ultraviolet light towers present in the enclosed space comprises establishing data communication between the controller and each of the at least two ultraviolet light towers and between each of the at least two ultraviolet light towers.

15. The method of claim 13 further comprising the step of supplying energy to the at least two independently placeable light towers by connecting said light towers in series such that at least one of independently placeable light towers supply energy to another of the independently placeable light towers.

16. The method of claim 13 wherein the step of establishing data communication between a controller and at least two independently placeable ultraviolet light towers present in the enclosed space comprises employing a wireless network.

17. A hard-surface disinfection system comprising:

at least two independently placeable ultraviolet light emitting towers;

a wireless communications system that allows information to be shared between the at least two independently placeable ultraviolet emitting towers.

18. The system of claim 17 wherein the wireless communications system comprises a communications module on each of the at least two independently placeable ultraviolet light emitting towers.

19. The system of claim 17 wherein the wireless communications system comprises a controller capable of remotely operating each of the at least two independently placeable ultraviolet light emitting towers.

20. The system of claim 17 wherein the wireless communication system further allows each of the at least two independently placeable ultraviolet light emitting towers to be activated by a single controller remotely.
