Abstract:
Disclosed is an LED-based luminaire (10, 110, 210, 310, 410, 510, 610, 710) including an optic surrounding a plurality of LEDs (140, 240, 340, 440, 540, 640a/b, 740). The optic may include a plurality of interior reflective surfaces for mixing light output of the LEDs and also include a transmissive diffuser (30, 130, 230, 330, 430, 530, 630a/b, 730a/b) through which interiorly reflected light output of the LEDs exits the LED-based luminaire.
