Abstract
A luminaire includes a luminaire control circuit and 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 is 200 nanometers (nm) to 230 nm wavelength. The luminaire receives a control signal based on at least the mounting height of the luminaire. The luminaire adjusts a UV radiation threshold limit based on the control signal. The luminaire controls, via a driver circuit, the disinfection light source over a dose cycle to emit the disinfection light continuously or during the 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.
