Abstract

Some embodiments of the present light fixtures include a body, a waveguide, and one or more independently-controllable light sources. The waveguide is configured to be coupled to the body and may include a first end configured to receive light emitted from at least one of the light source(s) and to direct the received light to (and in some embodiments, emit the received light from) a second end of the waveguide. In some embodiments of the present fixtures, the waveguide defines an opening through which light emitted from at least one of the light source(s) can pass, the light source(s) being coupled to the body such that a first one of the light source(s) emits light into the first end of the waveguide and a second one of the light source emits light through the opening.
