Abstract
A lighting assembly includes at least one light source array provided in a housing and a light scattering primary transmissive optical element having at least one focal region positioned substantially parallel or concentric with the light source array. Lens features of the optical element may include a Fresnel lens pattern to produce at least one focal region. An auxiliary transmissive optical element may be provided to further control light distribution and brightness uniformity.
