1. A lighting assembly comprising;
a. at least one light source array;
b. a housing; and
c. a primary transmissive optical element comprising a bulk light transmissive material with internal or surface texturing light scattering features and further comprising lens features with focal properties such that the primary transmissive optical element has at least one focal region inside the lighting assembly which is substantially parallel or concentric with the at least one light source array;
wherein a focal region of the primary optical element is spatially arranged with respect to the at least one light source array and to produce a targeted light distribution.
