Abstract
A light distribution apparatus for a light fixture includes an input coupler at a first end, at least one curvilinear waveguide extending between the first end and a second end, and a respective set of extraction features formed along the surface of the curvilinear waveguide. The input coupler may be positioned about a light source and direct light emitted therefrom into the pair of curvilinear waveguide. The curvilinear waveguide may transmit light from the input coupler toward the second end through total internal reflection. The extraction features cause light incident thereon to refract and exit the waveguide. The example light distribution apparatus may convey light from one or more light sources to one or more otherwise poorly lit regions of a light fixture, to provide enhanced aesthetics, without adding supplemental light sources or adversely compromising the design and structure of a light fixture.
