1. A luminaire comprising:
a waveguide body having a curved surface and a face normal to the curved surface;
a light extraction component comprising an array of light extraction elements disposed over the face of the waveguide body; and
a plurality of light emitting diodes (LEDs) configured to emit light into the curved surface of the waveguide body and positioned such that the plurality of LEDs have differing radial angular positions along the curved surface for steering an azimuthal component of illuminance distribution patterns of the luminaire in conjunction with the light extraction component.
