Abstract

A process for producing the profile of reflectors for a cylindrical source of light and reflectors obtained according to this process to illuminate a target surface with practically any desired illumination curve are disclosed. The profile of the reflectors comprising of four cylindrical reflective elements, denoted as the inner reflective elements (7, 7') and the outer reflective elements (5, 5'). The process comprises the following steps: defining the inner reflective elements; defining the location of one end (Rb) of the profile of the outer reflective elements; defining an illumination function E(q) corresponding to a desired illumination curve, connected to a luminance function L(q).
