Light diffusion optical fiber illumination, blue-violet light transmission system illumination, blue-violet light transmission system, and blue-violet light induced disinfection method

摘要

The disinfection method using the light diffusing fiber optically connects the light source with a light diffusing optical fiber having a core, a cladding surrounding the core, an outer surface, and a plurality of scattering structures located within the core, the cladding, or both the core and the cladding. It includes the step of. The method further includes optically engaging and positioning the light diffusing optical fiber with a pathogen sample, and directing the light output by the light source to the light diffusing optical fiber for a first time interval. The scattering structure scatters the light propagating along the light diffusing optical fiber toward the outer surface, and a part of the light is diffused through the outer surface, and at a wavelength of about 380 nm to about 495 nm for an exposure time of about 2 hours to about 24 hours. Pathogen samples are irradiated with light having an average power density of 5 mW/cm ² to about 30 mW/cm ² .
