ILLUMINATING LENS DESIGNED BY EXTRINSIC DIFFERENTIAL GEOMETRY

A grid (100, 200) defining illumination cells (110, 120, 230) having areas t o pass light from a source for use in generation of lines, wherein the grid is defined by first lines extending about one axis defined by the source, and second lines emanating from the axis to intersect first lines, each c...

Zusammenfassung:	A grid (100, 200) defining illumination cells (110, 120, 230) having areas t o pass light from a source for use in generation of lines, wherein the grid is defined by first lines extending about one axis defined by the source, and second lines emanating from the axis to intersect first lines, each cell having four edges defined by successive of first lines and successive of second lines, the cells having one of the following: (i) equal areas (ii) areas that increase in direction away from the source.
