Abstract: The present disclosure provides a novel construction for homogenizing light in a mirror-lined light duct, in particular such as in a light duct having an increase in the cross-sectional duct area in the light propagation direction. The present disclosure also provides for an apparatus for light homogenization after a portion of the light in a duct has been extracted from the duct and/or diverted to a side duct.

Abstract: The present disclosure describes advanced lighting elements, in particular solid-state lighting elements, and luminaires that include an array of lighting elements. The lighting elements, and luminaires including the lighting elements can exhibit benefits that include high optical efficiency and therefore high luminous efficacy; extraordinary directional control and therefore extraordinary glare control and efficacy of delivered lumens; and exceptional mixing of individual-device emission providing exceptional suppression of punch-through and color breakup. In many cases, the architecture can be amenable to low-cost manufacturing in a modular format.
