Claim 6:
7. An illumination system comprising:
an LED array comprising:
a plurality of LEDs, each LED separated from an adjacent LED in the array by a trench, each LED having sidewalls; and
a dynamic optical isolation material attached to a sidewall of a first LED in the array, the sidewall located in the trench between the first LED and another LED in the array, the dynamic optical isolation material switchable between a plurality of optical states comprising a first optical state configured to hinder a transmission of light through the dynamic optical isolation material and a second optical state configured to allow light to pass through the dynamic optical isolation material, the dynamic optical isolation material configured to switch between optical states based on a state trigger,
the trench between the first LED and the another LED in the array configured so that when the dynamic optical isolation material in the trench is in the second optical state, the trench is substantially transparent; and

one or more optical elements arranged to form an output illumination beam from light emitted by the LEDs in the LED array.
