Paper Abstract

A general theory on light-pipe/tunnel-based recycling schemes, along with some experimental data obtained from LED illuminators, is presented in this paper. Light recycling is classified as angular, spatial, or mixed based on the angular filtering characteristics of the recycling process. The principles behind the three schemes are analyzed and some experimental results are presented at the end.
