Abstract: A lighting system can comprise a light emitting diode that emits light, an optic mounted to process the emitted light, and an aperture disposed on the light-emitting side of the optic. The optic can comprise a cavity that receives the light. A portion of the received light can pass through a sidewall of the cavity, while another portion passes through a bottom of the cavity and out a front of the optic. The optic can comprise curved sides that receive the light passing through the cavity sidewall and reflect that light through the front of the optic. This reflection can condense the light to form a light beam having a beam waist. The beam waist can provide an annular separation or a radial gap between the beam of light and the aperture, with the separation providing clearance to avoid interference with the light beam.
