Abstract

A system of illumination for videoprojector is described, which comprises: a plurality of lamps (1, 1', 14, 14') adapted to generate a light beam; an integrating bar (3), in particular comprising an inlet face (4) and an outlet face (5), which allows to uniform the light beam generated by said plurality of lamps (1, 1', 14, 14'); a system of converging lenses (6), adapted to collect the light beam exiting from said integrating bar (3); wherein each lamp (1, 1', 14, 14') of said plurality of lamps(1, 1', 14, 14') is associated with a transparent deflecting prism (8), which allows to reduce the angular aperture of the light beam generated by said plurality of lamps(1, 1', 14, 14').
