Abstract
The present disclosure provides a novel construction for an illuminated light splitter in a mirror-lined light duct. In particular, the present disclosure addresses the ability to split partially collimated light travelling through a light duct into two different light ducts using light diverters, while extracting a portion of the light from each of the light ducts and also from the common intersection region. In some cases, the visual appearance of the illumination in the intersection region can appear non-uniform due to the presence of the light diverters, and the present disclosure provides an illuminated light duct splitter () configuration that homogenizes the output from the illuminated duct within the intersection region ().
