Abstract

A lens comprises an elongated shape. The lens has a short axis and a long axis. The lens comprises an upper surface through which a substantial majority of light exits the lens when a light emitting element is situated at or below a base of the lens. The upper surface includes a trough that extends along at least one of the short and the long axis. The upper surface includes a surface of a curved wall that joins the upper surface to the base of the lens. A lower surface of the trough is curved along the short axis and along the long axis. The lower surface of the trough has a curvature along the short axis that differs from a curvature along the long axis.
