The article presents the results of examinations concerning distribution of the luminous flux in the end-light lighting optical fibers, in which the end-surface was subject to deliberate shaping. A method for shaping the distribution of the luminous flux in lighting optical fibers was designed, devoid of using sockets and any additional heads shaping luminous intensity distribution.
