ABSTRACT:
A fiber-optic light system is disclosed for providing highly concentrated, cool light to projectors and reproducer sound heads, such as the type found in the projection room of a movie theater. The light beams onto a film to project the film's images onto a screen and release its soundtrack. In the preferred embodiment, a system is disclosed for providing fiber-optic light to a plurality of projector-and-reproducer sound sets from a single light source. A plurality of fiber-optic cables are connected to a standard xenon lamphouse, wherein each of the cables has a bifurcated "free" end with two trunks. One trunk removably connects to the projector by a coupling block that easily fits onto a mount attached to the projector's casing, while the other trunk connects to the reproducer sound head by a similar block and mount.
