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.
Claims9
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.
