An illumination lens (40, 50, 70, 81, 84) comprising: a two-dimensional beam-forming lens-profile configured to deflect light rays from a light source (37, 61) into a relatively narrow output beam; the lens-profile encloses a zone of higher refractive index than that of the area outside the profile where the higher refractive-index zone admits the light rays; a transverse axis of revolution extending transversely across and outside of the lens-profile; 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, the lens-profile further defining a focal zone from which the light rays diverge with a relatively wide angular swath such that the profile deflects the light rays from said focal zone into the relatively narrow output beam, with the transverse axis of revolution passing through the focal zone, a focal volume defined about the focal zone by the sweeping of the lens-profile about the axis of revolution, the focal volume being defined to receive the light source positioned at the focal zone, and TIR teeth (41, 51); characterized in that: the TIR teeth (41, 51) are formed on the inner portion of the surface of revolution facing the axis of revolution, whereby each TIR tooth comprises a first refractive surface and a second TIR surface, in the sense that light from the light source is first refracted on the refractive surface and then redirected radially outward on the TIR surface, so that the average beam direction of the output beam corresponds to equatorial or latitude emission. a two-dimensional beam-forming lens-profile configured to deflect light rays from a light source (37, 61) into a relatively narrow output beam; the lens-profile encloses a zone of higher refractive index than that of the area outside the profile where the higher refractive-index zone admits the light rays; a transverse axis of revolution extending transversely across and outside of the lens-profile; 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, the lens-profile further defining a focal zone from which the light rays diverge with a relatively wide angular swath such that the profile deflects the light rays from said focal zone into the relatively narrow output beam, with the transverse axis of revolution passing through the focal zone, a focal volume defined about the focal zone by the sweeping of the lens-profile about the axis of revolution, the focal volume being defined to receive the light source positioned at the focal zone, and TIR teeth (41, 51); the TIR teeth (41, 51) are formed on the inner portion of the surface of revolution facing the axis of revolution, whereby each TIR tooth comprises a first refractive surface and a second TIR surface, in the sense that light from the light source is first refracted on the refractive surface and then redirected radially outward on the TIR surface, so that the average beam direction of the output beam corresponds to equatorial or latitude emission.
