Claim:
1. An apparatus comprising: a light source sub-assembly having a length dimension extending in a first direction, a width dimension extending in a second direction perpendicular to the first direction, and a plurality of Light Emitting Diodes (LEDs) mounted in a first plane, wherein the width dimension is less than the length dimension; and a light conversion sub-assembly mounted above the first plane and physically separated from the plurality of LEDs and configured to mix and color convert light emitted from the light source sub-assembly, the light conversion sub-assembly comprising an output window, wherein a first portion of a first interior sidewall surface of the light conversion sub-assembly is aligned with the first direction and extends generally in a third direction between the first plane and the output window and is coated with a first type of wavelength converting material, wherein an entirety of a second interior sidewall surface aligned with the second direction and extends generally in the third direction between the first plane and the output window reflects incident light without color conversion.
