Claim 7:
8. A method of making a light converting optical system as recited in claim 1, further comprising providing an area-distributed lens array comprising a plurality of lenses arranged in rows and columns and each having a generally round aperture, wherein at least one of the first and second light converting semiconductor materials comprises quantum dots distributed within an optically transmissive material, wherein at least some of the lenses are formed by separate pieces of an optically clear material which are spaced apart from each other and attached to a common support substrate made from a different material, wherein the lenses are configured to receive light from the light source and direct the received light into a space between the first microstructured broad-area front surface and the thin sheet of reflective light scattering material, and wherein the continuous broad-area photoabsorptive film layer comprises a first optically transmissive protective layer disposed in contact with and bonded to a front surface of the active layer and a second optically transmissive protective layer disposed in contact with and bonded to a back surface of the active layer.
