Thus, only a small fraction of the light rays R1 will be deflected. Thus, the part R1 of the light rays R coming from the light source 13 and having passed through the primary optical element 140 propagates substantially in a straight line with a minimum of refraction through said connecting bridge 142 to the exit face 141b of the secondary optical element 141.

This allows the part R1 of the light rays R which had entered the connecting bridge 142 but which had not been able to be directed towards the exit. not the orientation of the optical emission axis X and thus avoid a lower brightness area at this location.
  • Said prisms 143 are located on the outlet face 141b, on the side opposite to that where the connecting bridge 142 is joined to the inlet face 141a.
  • said prisms 143 have the same thickness e as said at least one connecting bridge 142. This makes it possible to recover all of the light rays R1 coming from the connecting bridge 142.
