Paper Abstract

Two types of non-imaging systems have been modeled, a lighthouse and a crossed compound parabolic concentrator (CPC). Design tradeoffs have been made to control the radiant intensity of each system. An asymmetric design for the lighthouse system is evaluated and optimization of the crossed CPC design at the field edge is discussed. A tolerance study showing the effect of the surface reflectivity and source misalignment is presented. A comparison of theoretical predictions and system measurements agree within 5 percent.
