Abstract
A lighting system for illumination of an observation space, especially an observation space in which a pressurized and/or hot medium is contained, comprises an optical-fiber cable, one end of which can be connected to a light source, and a lighting head, which is connected to the other end of the optical-fiber cable and whose distal end can be introduced into the observation space through an opening in a wall enclosing the observation space. The lighting head comprises a light guide rod made from a pressure and/or temperature-resistant material.
