Claim 17:
18. A method of making a light converting optical system as recited in claim 14, further comprising providing an area-distributed lens array which comprises a plurality of convex lenses arranged in rows and columns and each having a generally round aperture, wherein the active layer comprises light scattering elements, wherein the photoabsorptive film 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, wherein at least some of the convex lenses are formed by separate pieces of an optically clear material, spaced apart from each other, and attached to a common support substrate made from a different material, and wherein the convex lenses are configured to receive light from the light source and direct the received light into a space between the microstructured broad-area front surface and the thin sheet of opaque reflective material.
