Abstract

General lighting applications often require a light patch with a specific shape and distribution. This work presents examples and details of a practical implementation of Oliker's ellipsoidal faceted reflector algorithm. We present example designs for various shapes of light patches. Uniformity and limitations of this technique are discussed. Analytical solution can be used to obtain a starting point for optimization. A technique to generate a smooth best fitting surface to meet manufacturing requirements is also presented.
