Abstract:
An optical element for a side emitting light that emits light from a light source at side directions relative to the horizon is disclosed. The optical element has an internal recess adapted to fit over a light source. The internal recess includes a collimating surface and interior refractive surfaces. An exterior refractive surface corresponding to the interior refractive surfaces is provided. A faceted prismatic reflecting surface corresponding with the collimating surface is provided. Light at a substantially horizontal angle relative to the horizon is emitted through the interior refractive surface through the exterior reflective surface to a side direction and light at a substantially vertical angle relative to the horizon is collimated by the collimating surface and reflected by the reflecting surface in the side direction.
