LED lighting is a rapidly evolving technology. Several decades ago, LEDs were only
suitable as indicator lights, but recent developments have made LED lighting a good …

We propose a design method for single reflectors that takes into account extended sources
with any arbitrary luminance distribution. This method is suitable for non-uniform prescribed …

In a previous paper we derived a generalized functional method of nonimaging optical
design, applicable in the case of axisymmetric or translationally symmetric geometries …

We establish a fundamental bound on the field of view over which strictly uniform far-field
irradiance can be achieved in symmetric two-dimensional (2D, troughlike) and three …

Reflectors for prescribed intensity or illuminance distributions are commonly used in
luminaires and automotive headlights. However, their design has remained a challenge …

Reflector design stemmed from the need to shape the light emitted by candles or lamps.
Over 2,000 years ago people realized that a mirror shaped as a parabola can concentrate …

We derive a generalized functional method of nonimaging optical design, applicable in the
case of axisymmetric or translationally symmetric geometries utilizing extended sources and …

TIR collimator are essential illumination components demanding high efficiency, accuracy,
and uniformity. Various illumination design methods have been developed for different …

The goal of the optical design of luminaires and other radiation distributors is to attain the
desired illumination on the target with a given source. Usually there are constraints that …
