For installing a fiber optic cable in a lighting unit for illumination purposes it is suitable to insert the end of the fiber bundle to a position where the end of the bundle is illuminated by the full cross section of a conical light beam, whereby it is also possible to operate with bundles of different diameters. For this purpose, the invention provides for a technique enabling a standard cable holder to be used in a highly qualified manner for different cables, with both a firm fixation of the cable end and a high finish thereof. A very accurate positioning of the cable end in the light beam is achievable without particularly high accuracy requirements in the adaptation of the holder to the specific diameter of the cable.
