Abstract:
A lighting device configured to deactivate dangerous microorganisms in an environment. The lighting device includes at least one lighting element with a single light source configured to provide disinfecting light. At least a first component of the light has a wavelength of about 405 nm, and at least a second component of the light has a wavelength of greater than 500 nm. The first component of light has a minimum integrated irradiance of 0.01 mW/cm2 measured from any unshielded point in the environment that is 1.5 m from any point on any external-most luminous surface of the lighting device.
