An optical radiation projector includes a reflector having at least two facing reflective surfaces, dimensioned and positioned with respect to each other and a radiation source to satisfy a selected set of dimensional relationships and which further comprises one fraction of a rear reflective part having at least one meridian section of circular arc shape centered axially forward of the radiation source so that the reflected radiation has a point of convergence situated forward of the outermost part of the source and for which the reflected radiation will have a substantially homogeneous distribution on a plane of utilization.
