Abstract
An example lighting device has a luminaire. The luminaire includes an illumination light source matrix including illumination light sources configured to be driven by electrical power to emit light rays for illumination lighting. The luminaire further includes an optical lens positioned and configured to extend over the illumination light source matrix and including an input surface coupled to receive incoming light rays emitted by the illumination light sources and an output surface. Both the input surface and the output surface each include at least two different aspherical, spherical, or planar portions to refract the incoming light rays emitted by the illumination light sources passing through to shape or steer the illumination lighting into an outputted beam pattern. A coupled illumination light source driver selectively controls the illumination light sources individually or in combination to adjust at least a beam angle of the outputted beam pattern from the optical lens.
