Abstract

See full text

A luminaire provides an asymmetric light distribution biased toward a forward horizontal direction. The luminaire includes a luminaire housing, light engines, dome optics, and first and second reflecting surfaces. The light engines emit light downwardly, and are in a row substantially orthogonal to the forward direction. Each of the dome optics is substantially similar, and refracts the light emitted by at least one of the light engines. The first reflecting surface reflects at least a first portion of the refracted light toward the forward direction, is proximate and behind each of the dome optics, forms an approximately vertical angle, and has a height greater than or equal to a height of the dome optics. The second reflecting surface is forward of the dome optics, forms an angle of 45 degrees or more with respect to vertical, and reflects downwardly at least a second portion of the refracted light.
