Abstract
A wall wash lighting fixture includes an input end at which light enters the fixture and an output end at which light exits the fixture. A longitudinal axis of the fixture extends longitudinally from the input end to the output end. The fixture includes a light source for emitting light into an interior of the fixture at the input end of the fixture. The fixture includes an optical element for receiving the light from the input end of the fixture. The optical element has a plurality of extraction elements for altering a path of the light passing through the fixture, such that light exiting the fixture at the output end of the fixture is directed laterally with respect to the longitudinal axis.

A wall wash lighting fixture, comprising:
- an input end at which light enters the fixture and an output end at which light exits the fixture, a longitudinal axis of the fixture extending longitudinally from the input end to the output end;
- a light source for emitting light into an interior of the fixture at the input end of the fixture;
- and
- an optical element for receiving the light from the input end of the fixture, the optical element comprising an interior surface and a plurality of extraction elements for altering a path of the light passing through the fixture, such that light exiting the fixture at the output end of the fixture is directed laterally with respect to the longitudinal axis, wherein the interior surface is configured to provide total internal reflection (TIR) of the light from the light source to the plurality of extraction elements at a plurality of different angles.
