Abstract
A high intensity fiber optic lighting system is described utilizing an incoherent light source, e.g. a xenon arc lamp having a pair of aligned electrodes positioned on the optic axis of a non-spheric reflector such as a parabolic reflector so that the forward electrode will not obstruct the transmission of light from the light source and reflector. The arc of the lamp is located at the focal point of the reflector. A condensor assembly which can comprise a pair of planoconvex lenses is positioned to receive incident rays from the reflector and direct them to a focal point located at the polished entry end of a bundle of optic fibers composed of a plurality of peripheral fibers surrounding a central fiber, all held together at the focal point of the condensing lens. The fibers at the opposite end of the fiber bundle diverge and are separated from one another so as to be freely movable and independently positionable at different locations, such as different positions and elevations on a stage for special lighting effects. A columnating lens is located to receive light from the outlet end of each fiber.
