<p>Lighted advertising sign, including at least one advertising panel and at least one light source, in which multichromatic optical filter means (14), exhibiting at least two chromatically differentiated filtering sectors (14.2, 14.3, 14.4) are disposed to intercept a beam of luminous radiations emitted by said at least one light source, to illuminate - directly or indirectly - said at least one advertising panel (11), and are movable with respect to said light source (13), so as to interpose, in selective mode or in automatic sequence, different ones of their filtering sectors (14.2, 14.3, 14.4) between said at least one light source (13) and said at least one panel (11), thus permitting the variation, continuously or according to selection by the user of the chromaticity of the luminous radiations passing through for the illumination of said panel. <IMAGE></p> |
