Abstract
A method of determining a drive signal provided to a light-emitting diode (LED). The method includes in response to determining that a second light intensity exceeds the expected light intensity, determining, via the controller, an artificial light intensity based on a task-to-sensor ratio, determining, via the controller, a total natural light intensity based on the second light intensity and the artificial light intensity, determining, via the controller, a non-useful natural light intensity based on the total natural light intensity, the first light intensity, and the task-to-sensor ratio, determining, via the controller, the drive signal based on a desired light intensity for the zone, the total natural light intensity, the non-useful natural light intensity, and the artificial light intensity, and controlling, via the controller, the driver to provide the second drive signal to the LED array.
