Abstract
An illumination system includes an array of LEDs including a plurality of first LEDs and a plurality of second LEDs. A microlens array overlays the plurality of LEDs and includes a plurality of first lenses corresponding to the plurality of first LEDs and a plurality of second lenses corresponding to the plurality of second LEDs. A first geometry of at least one of the plurality of first lenses is different than a second geometry of at least one of the plurality of second lenses. An imaging device is configured to capture an image based on light reflected from the array of LEDs. At least one processing device is in communication with the array of LEDs and the imaging device. The at least one processing device is configured to identify a shadow cast on the target region by an obstruction and selectively activate the array of LEDs based on the shadow.
