Abstract
Disinfection methods and apparatuses are provided which generate pulses of germicidal light at a frequency greater than 20 Hz and project the pulses of light to surfaces at least 1.0 meter from the disinfection apparatus. The pulses of light comprise a pulse duration and an energy flux sufficient to generate a power flux between approximately 200 W/mand approximately 5000 W/mof ultraviolet light in the wavelength range between 200 nm and 320 nm at the surfaces. Other disinfection methods and apparatuses are provided which generate pulses of light comprising germicidal light and visible light from a germicidal light source and generate pulses of light from a visible light source that is distinct from the germicidal light source. The projections of visible light from the light sources produce a continuous stream of visible light or a collective stream of visible light pulsed at a frequency greater than 60 Hz.
