Optical devices for providing corridor dual wallwash

A light fixture comprising:

• a light source assembly comprising at least one light source;
• and
• an optical device disposed adjacent to the at least one light source, wherein the optical device comprises:
• a quasi-semi-cylindrical outer perimeter comprising:
• a bottom surface that is substantially planar;
• a top surface located adjacent to the bottom surface, wherein the top surface has a curvature;
• and
• a pair of side surfaces located adjacent to the bottom surface and the top surface, wherein the pair of side surfaces are located opposite each other;
• a body bounded by the outer perimeter;
• and
• an inner optical feature disposed in the body at the bottom surface, wherein the inner optical feature forms a cavity bounded by at least four segments, wherein each two adjacent segments form an angle relative to each other,
• wherein the at least one light source is disposed in the cavity,
• wherein light emitted by the at least one light source travels through the cavity of the inner optical feature and is refracted by at least one of the at least four segments,
• wherein at least a portion of the light is subsequently reflected, through total internal reflection, off of one of the pair of side surfaces within the body,
• wherein the at least a portion of the light subsequently exits the body through and is refracted by the top surface of the quasi-semi-cylindrical outer perimeter, and
• wherein the inner optical feature is symmetrical along a virtual plane oriented along the length of the inner optical feature.

An optical device for a light fixture, the optical device comprising:

• a quasi-semi-cylindrical outer perimeter comprising:
• a substantially planar bottom surface;
• a top surface located adjacent to the bottom surface, wherein the top surface has a curvature along its length and a width;
• and
• a pair of side surfaces located adjacent to the bottom surface and the top surface,
• wherein the pair of side surfaces are located opposite each other;
• a body bounded by the outer perimeter;
• and
• an inner optical feature disposed in the body at the bottom surface, wherein the inner optical feature forms a cavity bounded by a plurality of segments, wherein each two adjacent segments form an angle relative to each other,
• wherein the cavity is configured to receive a light source of the light fixture,
• wherein the inner optical feature and the top surface are symmetrical about a virtual plane in the body that is perpendicular to the substantially planar bottom surface,
• wherein the virtual plane is oriented along the width of the substantially planar bottom surface, and wherein the virtual plane, when extended into the cavity, intersects a middle of the substantially planar bottom surface along a length of the substantially planar bottom surface, wherein at least a portion of the light is subsequently reflected, through total internal reflection, off of one of the pair of side surfaces within the body,
• wherein light emitted by the light source traverses through the top surface and forms a split beam on either side of the virtual plane with no direct down light along the virtual plane.
