Asymmetric vision enhancement optics, luminaires providing asymmetric light distributions and associated methods

A method for asymmetrically redirecting light from a plurality of light engines toward a forward horizontal direction, a direction opposite the forward horizontal direction being defined as a backward horizontal direction, the method comprising:

• emitting a first portion of the light from the plurality of light engines toward the backward horizontal direction;
• emitting a second portion of the light from the plurality of light engines toward the forward horizontal direction;
• emitting a third portion of the light from the plurality of light engines downwardly;
• reflecting at least part of the first portion of the light from a first reflecting surface, toward the forward horizontal direction;
• and
• reflecting at least part of the second portion of the light from a second reflecting surface, wherein the second reflecting surface forms an angle of 45 degrees or more with respect to vertical, so as to direct the at least part of the second portion of the light downwardly.

A light fixture configured to provide an asymmetrical light distribution, comprising:

• a housing;
• a plurality of light engines that are:
• coupled with the housing to form a substantially horizontal row, and
• configured to emit light generally downwardly;
• a substantially vertical first reflecting surface that is:
• coupled with the housing, and
• disposed on a rearward side of the row of light engines, so as to reflect a first portion of light from the light engines toward a forward direction;
• and a second reflecting surface that is
• coupled with the housing,
• disposed on a forward side of the row of light engines, and
• forms an angle of 45 degrees or more with respect to vertical, so as to reflect a second portion of light from the light engines downwardly.
