MODULAR LIGHTING SYSTEM, IN PARTICULAR FOR AIRPORT RUNWAYS AND TAXIWAYS.

摘要

A sand base plate (24) is set over the cavity as a cover. For each direction in which light is beamed there is at least one independent module (30) in the base plate so as to produce and beam the light, and this has a round lower surface with a diameter less than half the base plate diameter. - Each module (30) may be withdrawn individual upwards from the base plate; e.g. by a quick removal fastening, such as a quarter-turn spring connection. There are pref. between one and four modules. Each may have a bulb (1), reflector (3), a lens (7), and a mirror (6).
