Polarizing turning film using total internal reflection

Image Number 13 for United States Patent #7139125.

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.
