Abstract
A luminaire () includes a base () supporting multiple light-emitting elements (LEEs) (); and a first wall (-) and a second wall (-) each extending along a first direction (). The first and second walls (--) have light-reflective surfaces facing each other and forming a hollow channel (). The light-reflective surfaces have first portions () that curve in opposite directions, second portions () that are parallel, and third portions () that curve in like directions. The first portions () are arranged facing the LEEs () to provide an input aperture () that receives light from the LEEs (). The third portions () are arranged to provide an exit aperture () that outputs output light into an ambient environment. The first and second walls (--) are configured to propagate light from the input aperture () to the exit aperture ().
