摘要:
A device comprising a plurality of LEDs arranged in a coplanar array, the coplanar array comprising an LED at the center and LEDs positioned radially symmetrically around the LED at the center, and wherein the central axes of the LEDs are arranged to be parallel to each other; a one-piece lens array collimating light from the LEDs, the lens array comprising a plurality of coplanar lens tiles, the coplanar lens tiles comprising a lens tile at the center and lens tiles positioned radially symmetrically around the lens tile at the center, and wherein the central axis of each of the lens tiles is aligned with the central axis of a corresponding LED; and a focusing lens converging the collimated light from the lens array into a single image in a focal plane, wherein the central axis of the focusing lens is aligned with the central axis of the lens array.
