Abstract: A method of forming a lighting system comprises providing a cavity having at least a first array of first optical elements and a second array of second optical elements that have a different shape than the first array, filling the cavity with a curable resin, applying a secondary optical element to the curable resin in alignment with the first optical array, curing the resin to form a cured assembly, and removing the cured assembly from the cavity.
