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.
