Abstract

In many optical devices a task often arises to illuminate a rectangular-shaped area. With LEDs used as light sources, this task implies reshaping of the beam from a square Lambertian emitting surface to obtain a rectangular uniformly illuminated area ofappropriate dimensions and positioned above or decentered relative to the light source. We describe a new type ofrefractive lens developed for this purpose and the single-pass synthesis algorithm for its shape requiring no optimization step.
