1. An LED luminaire, comprising:
a. a luminaire housing defining a light output region;
b. a light guide configured to be located at the light output region, the light guide defining at least one directional light source location thereon;
c. at least one LED light engine located within the luminaire housing, comprising:
i. at least one LED light source; and
ii. a shroud having a shroud periphery and configured to operatively position the LED light source therein and inwardly spaced from the shroud periphery;
iii. the shroud periphery being positionable adjacent the light guide at the directional light source location, to deliver directional light via the directional light source location to a target location, in a target region beyond the luminaire;
iv. wherein the light guide is configured to optically couple with the shroud, and the shroud is configured to optically couple with the LED light source to define a non-directional light output to deliver non-directional light.
