Abstract
The present invention relates to a lighting device, comprising a cylindrical light source, a first reflector element (1, 20) which is symmetric with respect to a plane (P), of the type suitable for giving an area of uniform illumination, and at least one second reflector element (5,23), which is symmetric with respect to a plane (Q). This lighting device is characterised in that this second reflector element (5,23) is arranged downstream from the first, in such a way that its plane of symmetry (Q) is perpendicular at the same time to that (P) of the first reflector element and to the area of uniform illumination, and in that its base plane is coincident with the output plane of the first reflector element (1,20). <IMAGE>
