Abstract:
A method and apparatus for directing light from a light source along a trajectory to avoid particular obstacles and provide uniform illumination of a surface having a particular geometry such as a cylindrical geometry is described. The surface may enclose components such as PCBs that provide particular functionality that operate as obstacles to a light beam.
