Still for the example considered, the central isolux curve LV1 corresponds to a level of 32 lux. The following curves that surround it correspond to progressively decreasing levels.

  • the presence of the verticalized reflector R2 makes it possible, in the case of a crossover projector with cover 5, a better efficiency in flow relative to a projector with a single full ellipsoidal reflector.
  • the flux gain is of the order of 25% because the light beam produced by the verticalized reflector R2 is not reduced by the cover 5.
