Abstract

Certain exemplary embodiments can provide an apparatus and method for generating at least one radiation. The exemplary apparatus and/or method can selectively kill and/or affect at least one bacteria. For example, a radiation source first arrangement can be provided which is configured to generate at least one radiation having one or more wavelengths provided in a range of about 190 nanometers (nm) to about 230 nm, and at least one second arrangement can be provided which is configured to prevent the at least one radiation from having any wavelength that is outside of the range.

Claims (14)

1. An apparatus for generating at least one bactericidal radiation to expose at least one room surface thereto in an environment, comprising:

an ultraviolet (UV) source configured to generate the at least one radiation that kills a pathogen in the environment, wherein the at least one radiation has a peak wavelength provided in a range of 190 nanometers (nm) to 230 nm; and

at least one filter arrangement which includes at least one of:

(i) a bandpass filter, or

(ii) a combination of a low pass filter and a high pass filter,

wherein the at least one filter arrangement is configured to: (i) prevent all UVC wavelengths of the at least one generated bactericidal radiation that are outside of the range of 190 nm to 230 nm from passing through the at least one filter arrangement, and (ii) allow all wavelengths in the range of 190 nm to 230 nm to pass through the at least one filter arrangement.

2. The apparatus of claim 1 , wherein the at least one room surface includes a surface of at least one of a wall, a floor, a ceiling, a countertop, furniture, or a fixture.

3. The apparatus of claim 1 , wherein the at least one radiation is configured by the apparatus to avoid harm to cells of the body.

4. The apparatus of claim 1 , wherein the UV source includes a UV lamp.

5. The apparatus of claim 4 , wherein the UV lamp includes an excilamp.

6. The apparatus of claim 5 , wherein the excilamp includes at least one of a krypton-bromine lamp or a krypton-chlorine lamp.

7. The apparatus of claim 1 , wherein the at least one filter arrangement includes at least one of a chemical filter or a dielectric filter.

8. The apparatus of claim 1 , further comprising a radiation converting arrangement configured to convert the at least one radiation into a further radiation to be in a visible spectrum.

9. The apparatus of claim 8 , wherein the radiation converting arrangement comprises a fluorescent material.
