Abstract

This specification relates to an improved method, process and apparatus for disinfecting and sterilizing all types of surfaces and indoor air and room air contaminated with microorganisms. The improved apparatus consists of a multi-wavelength narrow spectral width UV source that is more effective than mercury based 254 nm germicidal lamps for destroying the DNA and outer shell or membrane of virus, bacteria, spores and cists.

Claims

1. A disinfecting apparatus comprising:

a dual-single line lamp comprising;

three triaxial tubes defining two annuli there between;

a first gas mixture selected to produce a first narrow wavelength photon emission; and

a second gas mixture different from the first gas mixture selected to produce a second narrow wavelength photon emission that is different from the first narrow wavelength photon emission;

a high voltage electrode located on a first tubular surface of one of the three triaxial tubes;

a ground electrode located on a second tubular surface of one of the three triaxial tubes, the second tubular surface located opposite the two annuli from the first tubular surface; and

a photon reflector secured in a spaced relationship to the dual-single line lamp positioned to direct photons to a zone or surface, whereby the disinfecting apparatus produces photons that are directed to a selected zone or surface and efficiently destroys or deactivates DNA organic bonds and proteins of microorganisms when the high voltage electrode is energized.

2. The disinfecting apparatus of claim 1, wherein the first and second narrow wavelength photon emissions are taken from the group consisting of 222 nm, 254 nm, and 282 nm.

3. The disinfecting apparatus of claim 1, wherein at least one lamp is an excimer lamp.

4. The disinfecting apparatus of claim 1, wherein the photon reflector is a gull wing-shaped director selected to direct at least 90% of emitted light to a planar surface.

5. The disinfecting apparatus of claim 1, the photon reflector comprising a barium sulfate composition for enhancing its reflective properties.

6. The disinfecting apparatus of claim 1 further comprising a box, wheels, and a handle suitable for use as a floor cleaning apparatus.

7. The disinfecting apparatus of claim 1 further comprising:

a handle attached to the dual-single line lamp; and

a surface detection mechanism adapted to shut off the dual-single line lamp when it is not near a surface to be disinfected.

8. The disinfecting apparatus of claim 1 further comprising:

an air duct surrounding the lamp mounted in a spaced relationship to the lamp to provide a selected action time in the airflow to disinfect the air.

9. A disinfecting apparatus comprising:

a first lamp and a second lamp each comprising;

a coaxial tube defining an annulus there between;

a first and second gas mixture selected to produce a first and second narrow wavelength photon emission different in each lamp, wherein the gas mixture and wavelength in the first lamp is different from the gas mixture and wavelength in the second lamp;

a high voltage electrode located on a first tubular surface of the tube of each of the first lamp and the second lamp;

a ground electrode located on a second tubular surface of the tube of each of the first lamp and the second lamp, the second tubular surface located opposite the annulus of the first lamp and the annulus of the second lamp from the first tubular surface; and

a first photon reflector and second photon reflector secured in a spaced relationship to the first lamp and second lamp respectively and positioned to direct photons from both lamps to a zone or surface, whereby the disinfecting apparatus produces photons that are directed to a selected zone or surface and efficiently destroys or deactivates DNA organic bonds and proteins of microorganisms when the high voltage electrode is energized.

10. The disinfecting apparatus of claim 9, wherein the first and second narrow wavelength photon emissions are taken from the group consisting of 222 nm, 254 nm, and 282 nm.

11. The disinfecting apparatus of claim 9, wherein at least one lamp is an excimer lamp.

12. The disinfecting apparatus of claim 9, wherein the photon reflector is a gull wing-shaped director selected to direct at least 90% of emitted light to a planar surface.

13. The disinfecting apparatus of claim 9, the photon reflector comprising a barium sulfate composition for enhancing its reflective properties.

14. The disinfecting apparatus of claim 9 further comprising:

an air duct surrounding the lamp mounted in a spaced relationship to the lamp to provide a selected action time in the airflow to disinfect the air.
