The light projector comprises a light source 2 and a reflector 3 which reflects part of the beam emitted by the source 2, the reflected beam and the non-reflected beam forming an output light beam with predetermined geometric characteristics. The source 2 is formed by cold light sources, such as light-emitting diodes 4 which may be oriented so as to increase or promote luminosity of the output beam along at least one given axis. The invention applies in particular to the signalling lanterns in railways. <IMAGE> |
