Abstract
An indoor disinfection system has a collection of lighting units. Each lighting unit includes a germicidal ultraviolet (GUV) light source emitting a GUV light cone with a cone angle less than 60 degrees. The GUV light cone contains optical power with wavelengths between 10-280 nm. A human presence sensor has a field of view cone angle greater than the GUV light cone angle. The human presence sensor generates a human presence signal in response to a human in the field of view. A controller receives the human presence signal and in response thereto disables the GUV light source.
