Abstract
A light shade can include a top surface formed by a plurality of adjacent, alternating peak and trough folds that define intervening facets, a bottom surface disposed opposite the top surface, and an edge surface transverse to and connecting the top surface and the bottom surface. The intervening facets can each be in the shape of a triangle with adjacent triangular facets sharing an edge. The shared edge can be one of a peak fold or a trough fold. One or more of the trough folds can have a plunge between the edge surface and an opposing side of the top surface. In an implementation, the light shade can be manufactured from a unitary polymeric sheet with the bottom surface being a mirror image of the top surface.
