Abstract: Devices, methods, and systems for disinfecting air and surfaces are described herein. The systems may include a source of light, a reflector, a motor, and a controller. The source of light may provide ultraviolet germicidal irradiation light and the light may be selectively provided. The reflector may extend along and/or around the source of light. The motor may be coupled to the reflector and cause the reflector to adjust relative to the source of light so as to direct light at different target locations. The controller may determine occupancy in a room in which the system is located. When the room is not occupied, the controller may cause the reflector to be adjusted to an unoccupied position. When the room is occupied, the controller may cause the reflector to be adjusted to an occupied position.
