Abstract
A remote light source lighting system is provided having an illuminator assembly including a housing. Held within the housing is a high intensity light source for providing light energy to a fiber optic cable bundle connected to the housing and facing the light source. The cable bundle includes a plurality of plastic optical fibers wherein at least one of the terminal ends of the bundle is formed by molding an optical quality resin around an optically transparent ferrule that binds the exposed ends of the optical fibers. The housing further includes a separate air plenum containing a blower. The blower produces a high velocity air stream directed precisely at the terminal end of the cable adjacent the light source to cool the terminal end.
