Abstract
Generally, the present disclosure provides a light duct bend used in a mirror-lined light duct system. In one aspect, the light duct bend includes an input region having a first propagation direction, an output region having a second propagation direction disposed at a bend angle to the first propagation direction, and a transition region connecting the input region to the output region. The transition region includes a plurality of vanes that subdivide the duct into channels, which can reduce the loss and/or disruption of collimation about one or more bends in the light duct system.
