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 system for disinfecting a room comprising:

a plurality of independently placeable energy emitter assemblies, each of the assemblies including a base, an elongate energy emitter extending vertically from said base, a fluency sensor, and a communications module;

a controller in data communication with at least one of the communications modules of the plurality of energy emitter assemblies;

wherein each of the communications modules is in data communication with either the controller or at least one of the other communications modules;

wherein for each of the plurality of energy emitter assemblies, the fluency sensor monitors a power output of the energy emitter to ensure that the energy emitter maintains an output over a threshold.

2. The system of claim 1 wherein the threshold comprises an absolute threshold.

3. The system of claim 1 wherein the threshold comprises a range within a set power output.

4. The system of claim 1 wherein the fluency sensor sends a signal to said controller if said power output drops below said threshold.

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

6. The system of claim 1 further comprising a motion detector on at least one of the plurality of energy emitter assemblies.

7. The system of claim 1 further comprising a safety feature capable of shutting off each of the plurality of energy emitters.

8. A method for disinfecting a space comprising:

placing a plurality of independently placeable energy emitter assemblies in a space;

for each of said plurality of independently placeable energy emitter assemblies, establishing communication with at least one of the other energy emitter assemblies or a controller, wherein at least one of the energy emitter assemblies is in communication with said controller;

energizing ultraviolet lights on each of the energy emitter assemblies;

monitoring a power output of each of the energy emitter assemblies;

allowing said ultraviolet lights to remain energized until a predetermined amount of time has elapsed based on characteristics of the space.

9. The method of claim 8 further comprising sending a signal to the controller if the power output of an energy emitter assembly drops below a threshold.

10. The method of claim 8 further comprising shutting down all of said plurality of energy emitter assemblies if motion is detected in said space.

11. The method of claim 8 wherein establishing communication with at least one of the other energy emitter assemblies or a controller, wherein at least one of the energy emitter assemblies is in communication with said controller comprises establishing communication between each of the energy emitter assemblies.

12. The method of claim 8 wherein establishing communication with at least one of the other energy emitter assemblies or a controller, wherein at least one of the energy emitter assemblies is in communication with said controller comprises establishing communication between the controller and each of the energy emitter assemblies.

13. The method of claim 8 further comprising displaying the power output of each of the energy emitter assemblies on said controller.

14. A system for disinfecting a room comprising:

a plurality of independently placeable ultraviolet light-emitting towers;

a wireless communications system that allows information to be shared between light-emitting towers and a controller.

15. The system of claim 14 wherein the communications system comprises a communications module on each of the plurality of light-emitting towers.

16. The system of claim 14 wherein the wireless communication system further allows each of the plurality of light-emitting towers to be activated by a single controller remotely.

17. The system of claim 14 further comprising a safety feature associated with each of the plurality of independently placeable ultraviolet light-emitting towers that is capable of shutting down each of the light-emitting towers if a safety condition is met.

18. The system of claim 17 wherein said safety feature comprises a motion detector and said safety condition is motion detected by said motion detector.

19. The system of claim 14 wherein each of the plurality of independently placeable ultraviolet light-emitting towers comprises a fluency sensor that monitors a power output of the light-emitting tower to ensure that the light emitting tower maintains an output over a threshold.

20. The system of claim 14 wherein the wireless communications system allows each of the light-emitting towers to share information with each other.
