If the lighting equipment in the runways of flvgplätsen built-in lighting equipment is required that the beam must exit the lighting equipment at an angle of approx. 3 ° to 4 °? so that the light beam hits the pilot's island during the ötart «and landing maneuvers, lighting devices for this $ w @ ok are betsanni; ₉ -8 * B _o in the form of luminaires in which a fcalotten -shaped metal housing with a sled for a leakage outlet protrudes from the runway level, or in the form of flat (Ilas hoods with mead that can be rolled over) that lie above the level. This AusfShnsngea w © i® @ a the SfeeJ part that more or less large © elevations over the runway are inevitable, so that rolling over © flight eyes are endangered by vibrations and heifenbruah,

Ss is also a lighting device-lieteaQBfe, which avoids this disadvantage _o With it, the lights are built into a shaft that ends with the star flag level. The light exit openings are laterally below the. 3tartb & hn level attached · So that the required © epitn exit angle is achieved, are in front of. the XiiGhtaustrltH voltages long, _β disposed in the efeartbabn "Länga7l (Slituag'liegende depressions or _e shafts The shaft © siad% v of tberrollbarkeit covered with longitudinally of the Startbsto host has This illumination device;. the part that the Lichtaustrittsöffhungen upstream rust *

This disadvantage is avoided in the lighting device to be installed in the runways for aircraft after the fire by at least one vertical prism that can be inserted into the runway together with a socket, that is, the side surface of the prism and that with it the Sfcartbeta ice © represent a flat plane, and one below the runway perpendicular to at least one other, to the runway g © ss © igt® & side of the "before the prism arranged"I> icht ^ u @ ll © ₀
