ABSTRACT:
A ventilated fiber optic bushing includes a bundle of elongated, optical fiber light guides having generally cylindrical diameters, each light guide having a first end remotely emitting light and terminating in a convex second end in a common plane. The bundle is held in a desired shape receiving light through a transparent window having the same size and shape as the fiber bundle, the window being transversely disposed in an aperture of a light projector wherein a cooling fan within the projector draws external air through the aperture around the window. A rigid tube holds the bundle of light guides in the desired shape within the aperture projector with the convex second ends of the guides against the transparent window. A portion of the external air drawn through the projector aperture is drawn longitudinally through interstices between the light guides and transversely between the interstices formed by the convex light guide ends and the transparent window. The rigid tube holding the bundle is removable from the projector aperture.
