Abstract
A collimator having an overall bowl shape. The collimator is rotationally symmetrical about an optical axis of the collimator, and has an output wall, an input recess opposite the output wall, the input recess being defined by an internal side wall and an internal upper wall which interrupts the internal side wall in such a way as to define an intersection region, the internal side wall and the internal upper wall being designed to allow an incident light ray to enter the collimator peripherally and centrally, respectively, and a peripheral reflective wall joining the output wall to the internal side wall, the surface of the internal side wall being designed in such a way that a straight line, which is tangential to the internal side wall and joins the intersection region, passes through the focal point of the collimator.
