ABSTRACT:
The invention relates to an airfield light, principally for marking aircraft parking lots, routes for ground staff, etc. It should be readily visible from all sides and from any angle, even in the poorest environmental conditions and from a relatively long distance. It consists of a light source which is arranged in a housing and radiates light in a hemisphere through at least one lens installed in the housing, the light beam (1) in the zenith of the hemisphere having a luminous intensity which is at least 20 percent higher than in the region (13) between 10 and 30 degrees above the lowermost radiant edge (2).
