A LIGHT SOURCE, FOR EXAMPLE FOR LIGHTING SURFACES

摘要

A lighting device for lighting a surface (S) includes: - a light radiation source (12) to produce a light radiation, - a first optical stage (14) to collect the light radiation and produce a collimated light beam (LC) therefrom, - a second optical stage (16) to deflect the collimated beam (LC) and generate a deflected light beam (LD), and - a third optical stage (18) to spread the deflected beam (LD) and generate a spread lighting beam (LS) for lighting the aforesaid surface (S).
