Abstract:
A light-directing apparatus for off-axial preferential-side distribution of light from a light emitter having an emitter axis. The light-directing apparatus includes a shield member within a lens member positioned over the light emitter. The lens member has an outer surface and an inner surface defining an emitter void and a shield-receiving void which is on a non-preferential side of the lens member. The shield-receiving void is different in configuration than the emitter void. The shield member is in the shield-receiving void in position in the path of light emitted toward the non-preferential side.
