Description

Technical Field

[0001] The utility model relates to the technical field of airport road lamps, in particular to an airport taxiway lamp. Background Art

[0002] Airport taxiway lights generally include runway centerline lights and runway boundary lights. Centerline lights are installed at the centerline of the runway, and boundary lights are installed at the boundary of the runway. During the landing process of the aircraft, these lights can enable the pilot to land accurately on the runway and move according to the prescribed route;

[0003] Birds often stay on the runway of the airport. When the plane is landing, the birds may hit the plane. The plane lands very fast and may cause damage to the plane. Although most boundary lights can play the role of emitting light indication signals, they basically have no function of driving away birds.

[0004] In addition, the boundary lights will generate heat during operation. If the heat cannot be dissipated in time, long-term use may cause the internal temperature of the lamp to rise, affecting the normal operation and service life of the lamp. Therefore, corresponding heat dissipation measures need to be taken to ensure the normal operation of the airport boundary lights;

[0005] In addition, the lamp bodies of most boundary lights and centerline lights are not interchangeable. During the maintenance process, replacement parts and tools for the two lamp bodies are often required, which increases the burden of airport taxiway light maintenance work. Utility Model Content
