Abstract
A luminaire is provided that includes an LED light engine emitting a light engine light beam and one or more optical devices configured to receive the light engine light beam and form a luminaire light beam emitted by the luminaire. The LED light engine includes an array of LED emitters mounted on a substrate, an array of lenses optically coupled to the array of LED emitters, and a plurality of filter regions. The filter regions of the plurality of filter regions are optically coupled to and fixedly mounted relative to the array of LED emitters. Each filter region of the plurality of filter regions is aligned with an associated LED of the array of LED emitters and is configured to filter substantially only light emitted by the associated LED.
