Abstract
An illumination system including at least one light source such as an electroluminescent element, e.g. a light emitting diode (LED), and at least one optical element whose surface is structured by diffraction and/or refraction type optical microstructures. In order to shape the beam, the optical element includes at least two sections whose optical microstructures and therefore optical properties are different from one another. The pattern of the microstructures in each of the at least two sections is, at least over a predetermined angular range, rotationally symmetric with respect to the optical axis or another symmetry axis.
