Off-axis and segment collimation and projection

Abstract

A light assembly including a central axis along which a light source is intended to be located. A ring lens at least partially surrounds the central axis, the lens having a central projection along a projection axis for projecting the light passing through the lens along the projection axis. The central projection and projection axis are at an angle with respect to the central axis and the angle is not a right angle. The ring lens has a conical entry face which is at an angle with said central axis. Another embodiment of the light assembly includes a central axis on which a light source is located and a ring lens at least partially surrounding the central axis. The lens is constructed and arranged to provide collimated light horizontally about a plane which is at a right angle to the central axis, and non-collimated light vertically and in directions which are perpendicular to tangents at the exit points of the rays from the lens.
