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 output surface includes an output lateral portion, an output shoulder portion, and an output body portion. One or both of the input surface or the output surface includes facets.
