US 2026/0256969 A1 · FIXED POSITION HYBRID GERMICIDAL IRRADIATION APPARATUS, METHOD, AND SYSTEM

Abstract

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