![]() The dimensions and locations of the holes are such that the optical fibers are held in a substantially parallel, generally even, spaced apart relationship. An optical fiber is received in each hole. In one embodiment the array member comprises a plate with a line of substantially evenly spaced holes formed therein. These and other difficulties of the prior art have been overcome according to the present invention.Ī preferred embodiment of the fiber optic light fixture according to the present invention comprises an array of optical fibers or filaments mounted in a spaced apart relationship in an array member. The successful projection of a line or band of light with sharp, crisp edges on an object over distances of several feet or more had generally eluded previous workers. is to precisely locate a spot on the patient for the application of x-rays. A lens is focused on the ends of the compressed bundle of fibers, and the resulting light is projected through a distance of up to 2 feet onto a patient. discloses a device in which optical fibers are compressed together in a flattened bundle. Proposals had been previously made for the generation of linear lines of light utilizing fiber optic arrays. When the sheet or beam of light is projected on the face of an object, a line or band of light with sharp, crisp edges is produced. The invention relates in general to fiber optic light fixtures and, in particular, to fiber optic light fixtures which generate a thin sheet of incoherent light with sharply defined surfaces. A method of claim 9 including heating said rough outlet end with radiant heat. A method of claim 9 including heating said rough outlet end with an open flame.ġ1. Heating said rough outlet end to at least its melting point and allowing it to cool until it is solidified to form said outlet end.ġ0. Holding said array member so that said rough outlet end is substantially level and Trimming said filament so that it is flush with said face to form a rough outlet end Mounting a fiber optic filament through a closely sized opening in an array member so that said filament projects beyond a face of said array member A method of forming an outlet end of a fiber optic filament, said method comprising: A method of claim 7 including providing a cylindrical rod lens.ĩ. ![]() Supplying light to said elongated lens through said fiber optic outlet ends andĪllowing said supplied light to exit said elongated lens as a sheet of light having sharply defined sides.Ĩ. Providing an elongated lens having a longitudinal axis positioned in a zone of sharpness relative to said fiber optic array, said elongated lens being adapted to elongate light received from said fiber optic outlet ends along said longitudinal axis and to compress such light in a direction which is generally normal to said longitudinal axis Providing a plurality of fiber optic outlet ends positioned in a fiber optic array A method of generating a sheet of incoherent light with sharply defined sides, said method comprising: An optical fiber fixture of claim 1 wherein said array line is a straight line.ħ. An optical fiber fixture of claim 1 wherein said outlet ends are convex.Ħ. An optical fiber fixture of claim 1 wherein said elongated lens comprises a cylindrical rod.ĥ. An optical fiber fixture of claim 1 wherein said outlet end comprises a formed in situ convex surface.Ĥ. ![]() An optical fiber fixture of claim 1 including a second fiber optic array defining a second array line.ģ. A fiber optic light fixture for generating a sheet or beam of light which has sharply defined opposed surfaces, said fiber optic light fixture comprising:Ī plurality of optical fibers, each such optical fiber including an outlet end adapted to emit a cone of light in a first direction Īn array member, said outlet ends being mounted to said array member in a fiber optic array, said fiber optic array defining an array line andĪn elongated lens having a longitudinal axis, said longitudinal axis being spaced from and substantially parallel to said array line, said elongated lens being adapted to elongate said cones of light along said longitudinal axis and to condense said cones of light in a lateral direction, said elongated lens being positioned within a zone of sharpness, the location of said zone of sharpness being determined by adjusting the distance between said longitudinal axis and the array line while observing the edges of the projection of the resulting sheet of light on a surface positioned substantially normal to said first direction, said zone of sharpness being where said edges are the sharpest.Ģ.
