Abstract

A powering device is configured to provide power to an ultraviolet (UV) lamp of a sanitizing system. The powering device includes a power delivery assembly configured to provide power to the UV lamp, and a power controller coupled to the power delivery assembly. The power controller is configured to control one or more aspects of the power provided from the power delivery assembly to the UV lamp.

First claim

What is claimed is:

1. A powering device configured to provide power to an ultraviolet (UV) lamp of a sanitizing system, the powering device comprising:
a power delivery assembly configured to provide power to the UV lamp;
a power controller coupled to the power delivery assembly, wherein the power controller is configured to control one or more aspects of the power provided from the power delivery assembly to the UV lamp; and
a power boost switch selectively actuatable to command a temporary power increase from the power delivery assembly to the UV lamp.

2. The powering device of claim 1 , wherein the UV lamp is within a sanitizing head of a wand assembly.

3. The powering device of claim 2 , wherein the powering device is within a backpack assembly coupled to the wand assembly.

4. The powering device of claim 1 , wherein the UV lamp is an excimer lamp configured to emit UV light having a wavelength of 222 nm.

5. The powering device of claim 1 , further comprising one or more potentiometers coupled to the power controller and configured to adjust or otherwise control frequency, pulse width modulation, and current with respect to the power provided to the UV lamp.

6. The powering device of claim 1 , wherein the power delivery assembly includes a battery pack and at least one capacitor, the at least one capacitor configured to receive electric current from the battery pack and supply the electric current to a transformer.

7. The powering device of claim 1 , further comprising:
a power switch;
and
a lamp power switch.

8. The powering device of claim 1 , further comprising a coupler that connects the power delivery assembly to the UV lamp.

9. The powering device of claim 8 , wherein the coupler comprises a twisted pair of insulated wires.

10. The powering device of claim 8 , wherein the coupler comprises a coaxial cable including an insulation layer and a metallic shielding layer that surrounds the insulation layer.

11. The powering device of claim 1 , further comprising a transformer disposed between the power delivery assembly and the UV lamp.

12. The powering device of claim 1 , wherein the power delivery assembly comprises an external power interface, a charger, a battery pack, and at least one capacitor, wherein the charger is configured to receive electric current from the external power interface and supply the electric current to at least one of the battery pack or the at least one capacitor.

13. A powering device configured to provide power to an ultraviolet (UV) lamp of a sanitizing system, the powering device comprising:
a power delivery assembly configured to provide power to the UV lamp, the power delivery assembly including a battery pack and at least one capacitor;
a power controller coupled to the power delivery assembly, wherein the power controller is configured to control one or more aspects of the power provided from the power delivery assembly to the UV lamp;
one or more potentiometers coupled to the power controller, wherein the one or more potentiometers are configured to adjust or otherwise control frequency, pulse width modulation, and current with respect to the power provided to the UV lamp;
a transformer disposed between the power delivery assembly and the UV lamp, the at least one capacitor configured to receive electric current from the battery pack and supply the electric current to the transformer; and
a coupler that connects the transformer to the UV lamp, wherein the coupler includes at least one insulated wire that is surrounded by a metallic shielding layer.

14. The powering device of claim 13 , wherein the at least one insulated wire of the coupler comprises a twisted pair of two insulated wires.

15. The powering device of claim 13 , wherein the power delivery assembly further comprises an external power interface and a charger, the external power interface configured to connect to an external power source, the charger configured to receive electric current from the external power source, via the external power interface, and supply the electric current to at least one of the battery pack or the at least one capacitor.

16. A powering device configured to provide power to an ultraviolet (UV) lamp of a sanitizing system, the powering device comprising:
a power delivery assembly configured to provide power to the UV lamp;
a power controller coupled to the power delivery assembly, wherein the power controller is configured to control one or more aspects of the power provided from the power delivery assembly to the UV lamp; and
a coupler that connects the power delivery assembly to the UV lamp, wherein the coupler comprises a coaxial cable including an insulation layer and a metallic shielding layer that surrounds the insulation layer.

17. The powering device of claim 16 , wherein the UV lamp is within a sanitizing head of a wand assembly.

18. The powering device of claim 16 , further comprising one or more potentiometers coupled to the power controller and configured to adjust or otherwise control frequency, pulse width modulation, and current with respect to the power provided to the UV lamp.

19. The powering device of claim 16 , wherein the power delivery assembly includes a battery pack and at least one capacitor, the at least one capacitor configured to receive electric current from the battery pack and supply the electric current to a transformer.

20. The powering device of claim 16 , wherein the power delivery assembly comprises an external power interface, a charger, a battery pack, and at least one capacitor, wherein the charger is configured to receive electric current from the external power interface and supply the electric current to at least one of the battery pack or the at least one capacitor.
