An exemplary directional light homogenizer includes a one-piece, hollow
hexagonal cross-section tube. The tube has an internal highly light
reflective surface. The tube defines a first end configured to receive a
non-homogenous light from a light source and a second end configured to
output homogenized light. At least one curved section is disposed between
the first end and the second end, and the curved section has a curvature
greater than zero degrees and less than one hundred eighty degrees. An
output section of the tube is straight, has a finite length, and
terminates at the second end.
