Abstract

A lighting device (1), in particular a suspended lamp, having a lamp-holder device (4) for receiving a light source (6); a first diffusing screen (7); a support (2) having an electric power lead (3) and integrally supporting the first diffusing screen (7) and the lamp-holder device (4); a second diffusing screen (20) housed between the lamp-holder device (4) and the first diffusing screen (7), and which is smaller than the first diffusing screen (7) and displaced with respect to the first diffusing screen (7) in a predetermined direction; and a carriage (25) integrally supporting said lamp-holder device (4) and movable, in said predetermined direction and along guide means (26) carried integrally by the support (2), between at least two predetermined operating positions, in at least one of which the second diffusing screen (20) does not intercept the light emitted by the light source (6).
