Abstract
An optical element with light scattering properties is configured for use in a light fixture or lighting module. When used in combination with a reflector or reflective surface proximate to an output face, the optical element can provide a range of non-Lambertian light distributions in alternative embodiments. The optical element utilizes combinations of dispersed light scattering particles and/or surface features to selectively scatter, disperse and internally reflect light. Using such optical arrangements it is possible to create light distributions with a single or multiple lobes or peak intensities and to control the position and shape of light distributions. The optical element is particularly suitable in low profile edge lit lighting assemblies used in indoor lighting products such as suspended, surface or recessed mounted linear light fixtures, ceiling mounted downlights, cove lights, and light fixtures for wall washing or perimeter lighting.
