Abstract: A portable UV-C disinfection apparatus, method, and system for ultraviolet germicidal irradiation. UV-C emitters may be coupled to an array housing having a planar array surface in a vertical configuration. UV-C sensors are configured to measure the amount of UV-C light or near UV-C light from a target surface. A controller may be communicably engaged with the UV-C sensors to determine the amount of UV-C radiation collected by the UV-C sensors. The controller includes instructions stored on a memory according to the amount of UV-C radiation collected corresponding to an effective kill-dose for surface disinfection. The improved apparatus, method, and system reduces exposure time by varying the intensity and wavelength of the UV-C administered, while concurrently reducing UV overexposure to surfaces by administering radiation through a rotational zonal application.

Abstract: A hybrid germicidal irradiation apparatus, method, and system for dual-band germicidal irradiation. A first plurality of emitters and a second plurality of emitters may be coupled to a housing configured to be coupled to a ceiling of an interior room. The first plurality of emitters and the second plurality of emitters may be operable to emit UV-C radiation at a wavelength of about 265 nanometers and near-UV radiation at a wavelength of about 405 nanometers, respectively. One or more radiation sensors are configured to measure the amount of UV-C light or near UV-C light reflected from a target surface. A controller may be communicably engaged with the radiation sensors to calculate an amount of UV-C radiation and near-UV radiation delivered to a target surface or interior space.

Abstract: An apparatus and method for reducing dosage time in ultraviolet germicidal irradiation systems. A UV-C reflective adhesive film may be configured as sheets, or in a roll that may be cut to a desired size or shape. A user may apply the UV-C reflective adhesive film to a desired surface of an interior room by exposing an adhesive surface to the desired interior surface. A reflective layer of the UV-C reflective adhesive film is configured to improve the reflectance percentage or reflectance pattern of a desired interior surface with respect to incident UV-C or near UV-C light. The improved reflectance properties of the desired surface functions to reflect a greater amount of light back to one or more closed-loop sensors in operation with a UV-C or near UV-C germicidal irradiation system.

The improved reflectance thereby reduces the amount of time required for one or more closed-loop sensors in operation with a UV-C or near UV-C germicidal irradiation system to measure an effective kill-dose for surface disinfection.
