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.

Abstract: A method for controlling an illumination system includes detecting a first position of a marker in image data. In response to the first position, a first light target for the first light emission is identified. Controlling a light assembly to direct the first light emission to the first light target and maintaining the first light emission directed to the first light target. The method further includes detecting a second position of the marker in the image data. A second light target for the second light emission is identified in response to the second position. The light assembly is controlled to direct the second light emission to the second light target.
