Abstract
The invention relates to a unidirectional lighting device for illuminating objects and/or for marking lanes, preferably in the airport area. Said device comprises a base having an external housing for placing and fastening the lighting device and optical components which comprise at least one light source, one reflector and one front glass and which produce a light beam along an optical axis. The external housing does not consist of metal and the optical components are disposed in an optical module to be added on to the base, thereby providing a lighting device which is easy to maintain.
