Abstract
An example lighting device includes a plurality of individually controllable illumination light sources configured to be driven by electrical power to emit light. The lighting device further includes an optical lens positioned over the illumination light sources for beam shaping or steering. The optical lens has a plurality of aspherical, spherical, planar, or freeform surfaces, including an input surface coupled to receive light from the illumination light sources and an output surface. The input surface includes an input peripheral portion and an input central portion. The input peripheral portion extends from the illumination light sources and includes a plurality of input peripheral segments that are discontinuous and in aggregate curve from a first region of the input surface near the illumination light sources to a second region of the input surface near the input central portion.
