Abstract

Disclosed are lighting arrangements that provide, when in operation, more uniform angular light distribution emissions into an environment. The lighting arrangements use LED light sources, a light scattering optical element and partial reflectance from a light transmissive sheet or reflective layer to produce direct and indirect illumination with improved angular light distribution and uniformity onto targeted illumination surfaces such as ceilings, walls, and floors. The present disclosure provides a solution to problems of non-uniform angular distribution of light causing visual discomfort and spatial discontinuity in output. Energy savings are achieved with high optical efficiency utilizing compact, durable, robust, and aesthetically appealing optical composites and lighting arrangements capable of providing an assortment of configurable angular light distributions.
