A light redirecting article redirects light toward a target angle. The
light redirecting article has an input surface for accepting incident
illumination over a range of incident angles and an output surface with a
plurality of light redirecting structures, each light redirecting
structure having an internal reflection surface oriented at a first angle
with respect to the plane of the input surface and an exit surface for
emitting an output light at an emitted light angle, wherein the exit
surface is oriented at a second angle relative the plane of the input
surface. For incident illumination at a principal angle greater than 60
degrees from normal, light is reflected from the internal reflection
surface and emitted from the exit surface at an emitted light angle that
is within 5 degrees of the target angle.
