These lights are mainly installed on some relatively high buildings, and their function is to remind some low-altitude aircraft, to make these low-altitude aircraft pay attention to avoidance, these lights also have a special name, called aviation obstruction lights. The country clearly stipulates that if the height of a building exceeds 45 meters, it is necessary to install aviation obstruction lights, and in addition to installing on the top, it must be installed around the building. It is required to be able to show the entire building. The general outline of the building is out, and after installation, the aircraft can evade in time.
Aviation obstruction lights refer to obstruction lights installed on fixed buildings, structures, moving objects in airports and other obstacles. The installation height of the obstruction lights needs to be in accordance with the relevant obstruction lights standards and specifications issued by the Civil Aviation Administration of China. The obstruction light fixtures installed are also different:
1. If the top of the object is more than 45 meters above the surrounding ground, obstruction lights must be installed in the middle layer for safety reasons, and the distance between the middle layer must be no more than 45 meters and equal as much as possible, and more than 100 meters in the city In the super-high buildings in China, it is especially necessary to consider installing obstruction lights on the middle layer, but when installing obstruction lights, try to avoid the surrounding residents from feeling uncomfortable. It is best to only see the scattered light from the ground!
2. For 105-meter-long ultra-high objects, facilities or cable towers, roof towers, etc., a medium-intensity A-type obstruction light should be installed at the top of the object, with a white flashing light, and a red medium-intensity B-type obstruction should be installed on the lower part. light.
3. Ultra-high objects higher than 150 meters (such as radio and television towers, long-span cable-stayed bridges, etc.) should be equipped with high-intensity A-type obstruction lights at the top, and medium and high-intensity obstruction lights should be used in conjunction.
