Abstract
A light fitting, preferably intended to be embedded in the surfacing of a runway, includes a light source (2) with a reflector (1) as well as a limiting light opening in the field of light. A mirror device is arranged for reflecting a part of the field of light (4) back towards the reflector (1) for sending this light through the light opening (3) after further reflection.
