An optical system (4) for mixing the light emitted by a plurality of light sources (2), the optical system (4) being provided with an optical mixer body (5) made of transparent material, presenting an inlet window (7) for collecting the light emitted by the light sources (2) and an outlet window (8) for supplying mixed light, and being constituted by a plurality of longitudinal portions (9) contiguous to one another, each of which is associated to a respective light source (2), extends between the inlet window (7) and the outlet window (8), has a respective optical axis (10) parallel to a longitudinal axis (6) of the mixer body (5) and a respective focus (11) lying on the optical axis (10) in a position corresponding to the inlet window (7) and centred on the corresponding light source (2) so that the light emitted by the latter will be collected and conveyed, towards the outlet window (8), by the longitudinal portion (9) itself. |
