Abstract: An LED luminaire having a housing positionable at a structure location for providing illumination. At least one first LED light engine is located within the housing. The housing has at least one light output boundary and is configured to direct light therein toward the light output boundary. A light guide is configured to be located at the light output boundary to receive light contained within the housing to emit non-directional light at the light output boundary. The at least one first LED light engine includes at least one first LED light source providing directional light at the light output boundary. The first LED light engine includes a shroud adjacent the light guide providing directional light from the LED light source to a target location beyond the luminaire. The shroud structure provides an optical path from the LED light source through the light guide for providing non-directional light.
