1. An optical system for a light emitting diode (13) which is incorporated in a fixed manner on an optical axis (14) of a carrier lens (12), said carrier lens (12) consisting of a front portion (18) with an outer transverse surface (25) formed concave towards emitted light, and for incorporating the diode (13), a longitudinal portion (19) with an outer longitudinal surface (22), wherein said outer longitudinal surface (22) is formed concave towards the diode (13) and is coaxial to the optical axis (14) of the carrier lens and said concave transverse surface (25) having a further outer transverse surface (24) circumscribed thereto characterised in that said outer longitudinal surface (22) has an ellipsoidal form and said further outer transverse surface (24) has a curved form.
