<p>LIGHT FIXTURE WIDE-ANGLE LIGHT DISTRIBUTION A lighting fixture includes a front end-portion having an edge defining a light opening and a back end-portion spaced from the opening which has a centerline. At least one LED emitter on the mounting board disposed at the back end-portion for directing light toward the opening, the emitter(s) being off-centerline in a first lateral direction. A lens for the emitter(s), the lens being configured for distribution of light from the emitter(s) primarily in a second lateral direction which is opposite the first lateral direction such that the light passes through the light opening at a portion of the edge that is off-centerline in the second lateral direction, thereby to widen the illumination angle from the fixture.</p> |
