Abstract
A lens for distribution of light predominantly toward a preferential side from a light emitter having an emitter axis. The lens has a faceted output region, a smooth output surface and at least one reflective surface which reflects light through total-internal-reflection (TIR) toward the faceted output region. The faceted output region is formed by pairs of transverse surfaces each surface of which redirects the received light to provide a composite illuminance pattern. The lens may further have faceted input surfaces at least partially defining a light-input cavity about the emitter axis. The faceted input region are formed by pairs of transverse surfaces each surface of which redirects the received light.
