Abstract
Il dispositivo di illuminazione comprende un blocco di materiale trasparente (1) delimitato da una coppia di superfici convergenti (2, 3) ed una sorgente di radiazione luminosa (4) disposta tra i piani a cui appartengono dette superfici convergenti, su una di queste superfici convergenti essendo disposti mezzi diffrattivi (6) su cui incide la radiazione luminosa.
