Abstract
A luminaire module includes at least one light-emitting element (LEE); a light guide (LG) extending in a first direction from a first end of LG to a second end of LG to receive at the first end light emitted by the LEE and configured to guide the light to the second end; and an optical extractor (OE) optically coupled to LG at the second end to receive light from the LEE guided from the first end to the second end of LG. OE includes a first interface configured to reflect a first portion of the light exiting the LG and transmit a second portion of the light exiting the LG so that the second portion of the light exits OE to an ambient environment in the first direction, and a second interface configured to transmit light incident thereon to the ambient environment in a direction different from the first direction.
