Patent attributes
A light-directing lensing member for off-axial preferential-side distribution of light from a light emitter having an emitter axis, including a base end with a perimeter-loop line defining a main plane transverse the emitter axis, and an outer surface configured for refracting light from the emitter in a predominantly off-axis direction toward the preferential side. The outer surface includes a major lens-portion and an axially-located minor lens-portion. The major lens portion outer surface has a front region centered on the front side, a back region centered on the back side, and a middle region around the emitter axis and contiguous with the front and back regions. The minor lens-portion has a surrounding-loop surface extending from the middle region transverse the main plane and terminating at an end surface configured to direct substantially axially-parallel light from the emitter in off-axis direction toward the preferential side.
