<p>The system includes a first luminous unit, of high relative intensity (F1), and a second luminous unit, of low relative intensity (F2). Each unit having a lighting surface (241,242) in which the luminous sources are situated. Each unit also has a collimation surface (81,82), the spacing (e2) between the lighting surface (242) and the collimation surface (82) of the second luminous unit (F2) is larger than the spacing (e1) between the lighting surface (241) and the surface of collimation (81) of the first luminous unit (F1).</p> |
