Lighting Device and Associated Method

Abstract

A lighting device comprising light radiation sources (12a, 12b, 12c, 12d) arranged in a plurality of cells (CI, C2, C3, C4) wherein each cell comprises at least one light radiation source, an output screen (16) for receiving light radiation from said light radiation sources (12a, 12b, 12c, 12d), and optical elements (18, 20) arranged between said cells (CI, C2, C3, C4) and said screen (16) so as to convey onto said screen (16) with a uniformly distributed intensity the light radiation produced by said light radiation sources (12a, 12b, 12c, 12d), the illumination of said screen (16) resulting from the superimposition of light radiation individually produced by the cells of said plurality (CI, C2, C3, C4).
