1. A luminaire, comprising:
multiple light-emitting elements (LEEs);
a base supporting the LEEs;
a first reflector comprising a first light-reflective surface circumscribing an axis; and
a second reflector comprising a second light-reflective surface circumscribing the axis and the first reflector,
wherein the first light-reflective surface is spaced apart from the second light-reflective surface, the first and second light-reflective surfaces face each other and collectively define a hollow channel, the hollow channel extending between an input aperture and an exit aperture that outputs output light into an ambient environment, the LEEs being arranged to direct light to the input aperture, the first and second light reflective surfaces are configured to propagate light from the input aperture toward the exit aperture, the hollow channel circumscribing the axis,
wherein, in one or more cross-sectional planes parallel to the axis, the first and second light-reflective surfaces have first portions that curve in opposite directions, and second portions that are straight, and third portions that curve in like directions.
