Abstract:
A light shaping article includes a solid optic having a cross-sectional profile including an input interface; a convex output surface opposite the input interface; a concave first side surface extending between the input interface and the convex output surface; and a second side surface opposite the concave first side surface extending from between input interface to the convex output surface. The concave first side surface and the convex output surface are configured such that, when the solid optic receives input light having an input angular range in a plane of the cross-sectional profile, the solid optic guides the light to and emits the light from the output surface in an output angular range in the plane. A prevalent propagation direction of output light in the output angular range is tilted toward the second side surface relative to a prevalent propagation direction of input light in the input angular range.
