Abstract

See full text

A method of inactivating one or more pathogens in an environment. The method includes providing light from at least one lighting element of a lighting device installed in the environment, the at least one lighting element configured to provide light toward a target area in the environment, the provided light having at least a pathogen-inactivating first component in a first range of wavelengths of 400 nanometers to 420 nanometers. The pathogen-inactivating first component of light produces an irradiance of at least 0.01 mW/cm2 as measured at a surface in the target area that is unshielded from the lighting device and located at a distance of 1.5 meters from an external-most luminous surface of the lighting device. Providing the light causes the one or more pathogens to be inactivated.
