Abstract:
Optics for asymmetrically redirecting light from one or more light engines include a dome optic, and first and second reflecting surfaces. The dome optic refracts light emitted by the light engines. The first reflecting surface redirects at least a portion of the light that is initially emitted toward a backward horizontal direction, toward the forward horizontal direction. The first reflecting surface extends substantially vertically and along a transverse horizontal direction, proximate to and behind the dome optic, and has a height greater than or equal to a height of the dome optic. The second reflecting surface reflects downwardly at least a portion of the refracted light that is initially emitted in the forward horizontal direction. The second reflecting surface is proximate to the dome optic and forward of the dome optic, and forms an angle of 45 degrees or more with respect to vertical.
