Abstract (en)
The signaling device comprises one or more light sources (39, 39) and a converging frontal projection lens (31), which produces a beam output from the signaling device. The light source(s) are formed of a matrix of light emitting diodes (39). Moreover, at least one optical concentration system (41) is provided, which concentrates the emission lobes (L) of the LEDs (39) in the focus of the frontal projection lens (31), wherein a field diaphragm (33) is disposed. <IMAGE>
