Abstract
The disclosure describes an antimicrobial protection device using antibacterial and virucidal electromagnetic energy to provide protection. Electromagnetic energy may be supplied by light source(s) such as LED(s). Lighting apparatus may be configured to project electromagnetic energy in an energy barrier over an individual or portion thereof, such as the individual's airways and eyes. Light source(s) may be constructed or configured to emit electromagnetic energy in wavelengths at about 405 nm and/or between about 200 nm to about 220 nm. Lighting apparatus may be configured in a ring and may be mounted above the user's head such that the lighting apparatus projects a bactericidal and/or virucidal curtain of light around the user's head, killing or inactivating microbes before reaching the user's eyes, nose, or mouth. Apparatus of the present disclosure may be useful for medically fragile children (including those in wheelchairs), medically fragile people, and medical personnel in high-risk infectious areas.
