Abstract

The present embodiments provide methods and apparatuses for providing prescribed illumination. Some embodiments provide lenses (30, 40) that include a two-dimensional beam-forming lens-profile where the profile acts to deflect light rays (38, 46) from a light source (37, 61) into a relatively narrow output beam (47). A zone of higher refractive index than that of the area outside the profile is enclosed where the higher refractive-index zone admits the light rays, a transverse axis of revolution (34, 42) is further included and extends transversely across and outside of the lens-profile so that the transverse axis extends generally laterally with respect to a luminous centroid-direction of the output beam. The lens further includes a surface of revolution formed by circularly sweeping the lens-profile about the axis .of revolution forming a circumferential beam from the output beam emitted by said surface of revolution.
