Abstract
Systems and methods for combined HINS and non-HINS lighting for surface disinfection. A lighting system controller is provided, which includes a memory, an i/o interface, and an electronic processor. The processor is configured to retrieve from the memory at least one characteristic of an area to be disinfected; determine, based on a signal received from a first sensor positioned to sense the presence of a person in the area, whether a person is present in the area; and, when a person is present in the area, determine a first drive signal based on the at least one characteristic and the presence of the person, and a second drive signal based on the presence of the person in the area and the first drive signal. The processor provides the first drive signal to drive to a HINS LED array and the second drive signal to drive a non-HINS LED array.
