Abstract
Generally, the present disclosure provides for a light engine, in particular a rack-mounted light engine that can be used in a lighting system. The rack mounted light engine can be positioned in an electronics component rack such a light distribution system using hollow light ducts may distribute the light over a large area, such as a data center. Such a light distribution can use a generated light more efficiently by directing the light to the fronts or backs of the electronics cabinet, rather than for general room illumination.
