Claim of US Patent No. 10,194,495
1. A method comprising:mounting one or more light emitting diodes (LEDs) on a printed circuit board, the printed circuit board having a first alignment feature;
optically sensing a position of the one or more LEDs mounted on the printed circuit board;
modifying the first alignment feature on the printed circuit hoard, based on the optical sensing of the position of the one or more LEDs, to form a modified alignment feature on the printed circuit board that modifies the space made available by the first alignment feature; and
aligning secondary optics with the one or more LEDs by mounting the printed circuit board on a support surface using the modified alignment feature such that a misalignment of the LEDs on the printed circuit board is offset by the modified alignment feature.
optically sensing a position of the one or more LEDs mounted on the printed circuit board;
modifying the first alignment feature on the printed circuit hoard, based on the optical sensing of the position of the one or more LEDs, to form a modified alignment feature on the printed circuit board that modifies the space made available by the first alignment feature; and
