Lighting device with optical lens for beam shaping and refractive segments

An optical device comprising:

• a plurality of optical-to-electrical transducers, each optical-to-electrical transducer being configured to be driven by received light to produce a respective electrical signal and to be individually activated for outputting the respective electrical signal in response to light;
• and
• an optical lens positioned over the optical-to-electrical transducers, the optical lens having a plurality of aspherical, spherical, planar, or freeform surfaces, including an input surface and an output surface coupled to direct light to the optical-to-electrical transducers;
• wherein:
• the input surface includes an input lateral portion, an input shoulder portion, and an input body portion,
• the output surface includes an output peripheral portion and an output central portion,
• the input lateral portion extends towards the optical-to-electrical transducers, curves towards the output peripheral portion, and intersects the input shoulder portion,
• the input shoulder portion abuts the input body portion,
• the input body portion includes a plurality of input body segments that are discontinuous and in aggregate curve outwards in a direction away from the optical-to-electrical transducers and the input shoulder portion,
• the output peripheral portion includes a plurality of output peripheral segments that are discontinuous and in aggregate curve from a first region of the output surface near the optical-to-electrical transducers to a second region of the output surface near the output central portion, and
• the output central portion includes a plurality of output central segments that are discontinuous.
