Publication number: 20100238409Abstract: An apparatus (1) for projecting images in sequence comprises a light source arranged in such a way as to direct a light beam in a direction of projection, a plurality of filters (4) with impressed shapes, able to project images corresponding to said shapes when traversed by the light beam, a conveyor element (5) defining a closed line, movable in continuous cycle, the filters (4) being associated to the conveyor element in such a way as to intercept the light beam to generate an animated effect in the projection; the conveyor (5) defines a line having at least one rectilinear segment arranged in such a way that the filters (4) intercept the light beam moving along a straight line perpendicular to the light beam. The projections can be of planar geometric shapes applicable to any lighting apparatus. In projection apparatuses currently in use, the animated effects obtained by moving filters have poor effectiveness, because the filters are constrained to move with circular trajectory.Type: ApplicationFiled: January 30, 2008Publication date: September 23, 2010Applicant: COEMAR S.P.A.Inventors: Fabio Allegri, Mauro Favalli

Publication number: 20100214782Abstract: A projector (1) for lighting surfaces and creating light effects comprises a plurality of lighting bodies (3), each able to generate a light beam in a direction of projection, and means for actuating the lighting bodies (3) to vary the orientation of the corresponding light beams as well as light sources (4) able to generate colour or to be filtered. Known projectors for lighting architectural details or surfaces in the entertainment sector do not allow to vary and adjust the projected light beam at will.Type: ApplicationFiled: January 30, 2008Publication date: August 26, 2010Applicant: COEMAR S.P.A.Inventor: Fabio Allegri
