A light device (1b) for generating in use a first photometric projection (P2,P3) having requirements of width and intensity such to fulfill a predetermined light distribution law defined by a required photometric projection (P1), including a plurality of modules (M), each of which including a light source (5) and means (6) for distributing the radiation emitted by the light source so as to generate a second photometric projection (P2') which has, along at least one axis of a pair of orthogonal axes (C1,C2) defining the laying plane of the mentioned photometric projections, a greater width than the width required for the first photometric projection (P2,P3) along such axis, according to the predetermined law; the punctual intensity of each second photometric projection generated by the modules (M) being always lower than that of the first photometric projection (P2,P3) and the second photometric projections being at least partially overlapped on one another so as to generate the punctual intensity required for the first photometric projection (P2,P3) so as to have the required photometric projection (P1) include therein. |
