Claim 0:
1. An antimicrobial system, comprising:
a disinfection light control device to generate a control signal to control emission of a disinfection light in an ultraviolet (UV) band for disinfecting a vicinity of a space of a target pathogen;
a luminaire including or coupled to the disinfection light control device, the luminaire comprising:
a disinfection light source to emit the disinfection light in the UV band for disinfecting the vicinity of the space of the target pathogen that is exposed to the disinfection light, the UV band being between 200 nanometers (nm) to 230 nm;
a driver circuit coupled to 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 by the luminaire processor and including:
a UV radiation threshold limit for safe exposure of a human to the UV band over a predetermined dose period,
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 or multiple thereof, and
a target pathogen UV radiation level that is sufficient to reduce the target pathogen by a desired amount in the vicinity over the predetermined dose period; 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 from the disinfection light control device; and
in response to receiving the control signal, 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 UV radiation threshold limit.
