Claim 11:
12. A method of making a light converting optical system as recited in claim 1, wherein the second optical layer comprises an area-distributed array of linear cylindrical lenses integrally formed in a surface of an optically transmissive sheet substrate, wherein the second optical layer is configured to receive light at a first location and guide the received light towards a different location using optical transmission and total internal reflection and comprises an area-distributed plurality of discrete surface relief structures each having a curvilinear wall, wherein the linear cylindrical lenses are disposed side by side and extend parallel to each other between two opposite edges of the optically transmissive sheet substrate, and wherein a total area of each of the plurality of discrete surface relief structures is less than a total area of each of the linear cylindrical lenses by at least 20 times.
