Abstract
An example lighting device has illumination light sources, each configured to be independently driven. The device further includes an optical lens positioned over the illumination light sources. The optical lens has a number of aspheric or spheric convex surfaces, including an input surface 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 curves from a region of the illumination light sources towards the input central portion. The input central portion curves towards the illumination light sources. The output surface includes an output lateral portion, an output shoulder portion, and an output body portion. Another example uses optical-to-electrical transducers, e.g. light detector or photovoltaic devices, in combination with the optical lens, for light reception transducer applications.
