Abstract

A lighting device configured to deactivate MRSA bacteria in air in an environment, including a housing; a light-emitting diode (LED) configured to emit light having a wavelength of about 470 nm; a light converting phosphor coating; wherein a first component of the light emitted by the LED travels through the light converting phosphor coating without alteration, and a second component of light emitted by the LED is converted by the converting phosphor coating into light having a wavelength of greater than 500 nm; wherein the first component of the light has a minimum integrated irradiance of 0.01 mW/cm2; wherein the first component of the light emitted by the LED and the second component of light emitted by the LED mix to form a combined light, with the combined light being visible light; and means for directing the combined visible light to the air in the environment.
