1. A luminaire, comprising:
a disinfection light source to emit a disinfection light in an ultraviolet (UV) band for disinfecting a vicinity of a physical space of a target pathogen that is exposed to the disinfection light, the UV band being 200 nanometers (nm) to 230 nm wavelength;
a driver circuit coupled to control the disinfection light source to control light source operation of the disinfection light source;
a luminaire control circuit including:
a luminaire processor coupled to the driver circuit and configured to control the disinfection light source via the driver circuit;
a luminaire memory accessible to the luminaire processor and including:
a control signal to control emission of the disinfection light in the UV band for disinfecting the vicinity of the physical space of the target pathogen, wherein the control signal is based on at least a mounting height of the luminaire,
a UV radiation threshold limit for safe exposure of a human to the UV band over a predetermined dose period in response to the control signal based on at least the mounting height of the luminaire,
a total UV radiation threshold exposure level over a dose cycle of the vicinity, the dose cycle corresponding to the predetermined dose period or being a fraction thereof, and
a target pathogen UV radiation level that is sufficient to deactivate the target pathogen in the vicinity over the predetermined dose period based on at least the mounting height of the luminaire; and
exposure and dosage control programming in the luminaire memory, wherein execution of the exposure and dosage control programming by the luminaire processor configures the luminaire to perform functions, including functions to:
receive the control signal based on at least the mounting height of the luminaire;
in response to receiving the control signal, adjust the UV radiation threshold limit based on the control signal; and
control, via the driver circuit, the disinfection light source over the dose cycle to emit the disinfection light continuously or during a plurality of periods for disinfecting the vicinity to substantially obtain the target pathogen UV radiation level and restrict the total UV radiation threshold exposure level by the adjusted UV radiation threshold limit based on the control signal.
