Abstract

The end section has a connecting element with a longitudinal bore in which the end of the light conducting bar is fastened. The whole, together with a lens system, is mounted in a case. An elongated optical part (20) is provided in the connecting element for optical coupling between the light conducting bar (15) and a lens (13). Its one end is in the connecting element, and its other end lies at the focus of lens (13). The connecting element has longitudinal elastic holding elements (17) which hold together and correctly align corresponding ends of light conducting bar (15) and the elongated element (20).
