Abstract

In this publication we investigate the optical design of a illumination system with a fly's eye integrator for LED projection displays. We compare the performance of CPC-like collimators and tapered light pipes with respect to their optical efficiency. We show that the tapered light pipes with a lens are more efficient and can be used to collimate the light of rectangular LED modules too. Using these tapered light pipes we design an illumination system with tilted collimators. This adapted 2F processor makes a more compact illumination system possible.
