    摘要： An optical output device comprises a plate having at least one surface formed as an array of tessellated lenses. The tessellated lenses comprise at least first and second regions of regular hexagonal lens tessellation, wherein the first and second regions are slanted with respect to each other. By removing full periodicity in this way, but maintaining localized periodicity, visible non-uniformities are reduced in both color and intensity. The optical output device does not need to be illuminated uniformly to generate an output without visible intensity or color edges.

    摘要： A dielectric collimator (1) comprising a center lens (3), the center lens comprising a light input surface (31) and a light exit surface (32), the light exit surface (32) being convex and substantially hemispherical, and the light input surface (31) comprising a central surface section (312) forming a light transmitting portion of the center lens adapted for receiving incoming light (5) and transmitting it to be emitted from the light exit surface, and a peripherally extending, annular outer surface section (311) being substantially plane and adapted for redirecting incoming light (5) in such a manner that the redirected light (7) undergoes TIR at the light exit surface and is emitted back out of the light input surface.
