Abstract
Lighting devices are provided for efficiently distributing light over an area to provided uniform illumination over a wide angle or other tailored illumination patterns. Each light device has at least one light source, at least one collimator for partially collimating light from the light source, and at least one diffuser for diffusing light from the collimator. The diffuser provides diffused light over an area from the diffuser having an intensity that is angularly dependent in accordance with the angular distribution intensity of light outputted from the collimator, so as to provide a predetermined illumination pattern from the device. The light sources and collimators may be provided in one or two-dimensional arrays, and a single diffuser may be formed on each collimator or the diffuser may be along a plate spaced from the collimators.
