SEMICONDUCTOR LIGHT SOURCE FOR EMITTING AND RECEIVING LIGHT BEAMS, AND LIGHTING SYSTEM COMPRISING SUCH A SOURCE

The invention relates to a semiconductor light source comprising a plurality of electroluminescent rods (61, 62) of submillimetric dimensions. The source is characterized in that at least some rods (61) are electrically connected to one another in a first assembly dedicated to the emission of a light beam substantially at a first wavelength, and other rods (62) are electrically connected to one another in a second assembly dedicated to the reception of a light beam substantially at a second wavelength, the first assembly and the second assembly respectively forming a distinct emission zone and reception zone.
