<p>A device and system for projecting images onto a screen, wherein the device and devices which are included in the system have associated therewith components comprising a light source, a cooling means for the light source, at least one of a reflector adapted to focus light from the light source and a focusing lens that receives light from the light source, a dynamic colour filter that receives light from at least one of the light source/reflector and the focusing lens, a light-shaping lens or rod that transmits light which has passed through the filter, an image-forming element that receives light from the light-shaping lens or rod, and a lens for projecting onto the screen images received from the image- forming element. At least the light source and the cooling means are placed in a first component housing separate from the other components that are located in at least one further component housing, and the connection between the component housings is effected by at least one liquid light guide. The system is characterised in that at least said light source and cooling means are installed in a plurality of first component housings or in one first component housing common to the projector devices, that other components associated with each projector device are arranged in at least one respective further component housing separate from said respective or common first component housing, and that respective liquid light guides connect said further component housings and said respective component housings or the common first component housing. The screen and at least one of said further component housings are placed in a projection room separated from rooms in which the other component housings are placed, thereby obtaining a substantial noise reduction in the projection room.</p> |
