One of the most interesting problems in the illumination research community is the design of optics able to generate prescribed intensity patterns with extended input sources. Such optics would be ideally applied to the current generation of extended

We present a compact freeform optic, called Freeform Shell-Mixer, which, when placed on top of a multicolor light source (particularly, a multi-chip LED), turns it into a virtual source in which colors are uniformly mixed. The optic, compatible with

Multi-chip and large size LEDs dominate the lighting market in developed countries these days. Nevertheless, a general optical design method to create prescribed intensity patterns for this type of extended sources does not exist. We present a design

Placing a plane mirror between the primary lens and the receiver in a Fresnel Köhler (FK) concentrator gives birth to a quite different CPV system where all the high-tech components sit on a common plane, that of the primary lens panels. The idea en

Most CPV systems are based on Fresnel lenses. Among these, LPI-patented Fresnel-Kohler (FK) concentrator outstands owing to performance and practical reasons. The Ventana{trade mark, serif} power train is the first off-the-shelf commercial product ba
