Abstract
A method of determining a drive signal provided to a light-emitting diode (LED). The method including sensing, via a first sensor, a first light intensity corresponding to a natural light in a room, sensing, via a second sensor, a second light intensity for a zone of the room, determining, via the controller, an expected light intensity, and determining, via the controller, whether the second light intensity exceeds the expected light intensity. The method further including, in response to determining that the second light intensity exceeds the expected light intensity, determining, via the controller, an artificial light intensity, determining, via the controller, the drive signal based on a desired light intensity for the zone of the room, the artificial light intensity, the first light intensity, and the second light intensity, and controlling, via the controller, the driver to provide the drive signal to the LED array.
