ROOM AND AREA DISINFECTION UTILIZING PULSED LIGHT WITH MODULATED POWER FLUX AND LIGHT SYSTEMS WITH VISIBLE LIGHT COMPENSATION BETWEEN PULSES

摘要

The present invention provides a sterilization method and apparatus for generating a sterilizing light pulse at a frequency greater than 20 Hz and projecting a phase light pulse onto surfaces at least 1.0 meter away from the sterilizing device. The pulse of light sufficient to produce ultraviolet light in the wavelength range of 200 nm to 320 nm, with a power flux of approximately 200 W/m ² to 5000 W/m ^{2 on} the surfaces ( pulse duration) and energy flux. The present invention provides another sterilization method and apparatus for generating light pulses comprising sterilizing light and visible light from a sterilizing light source and generating light pulses from a visible light source different from the sterilizing light source. Projection of visible light from a light source creates a continuous stream of visible light or a collective stream of visible light pulsed at a frequency greater than 60 Hz.
