Aircraft Warning Lights for Building

Building warning lights are devices used to provide visual warnings at night or in bad weather conditions. Their main purpose is to alert aircraft in the air to the location and height of high-rise buildings to prevent collisions between aircraft and buildings. Such lights are usually installed on the top or high places of buildings, communication towers, bridges or other tall structures. They can be clearly seen at night or in haze, helping pilots determine the location and height of buildings.

Types and applications of building warning lights

Navigation Obstruction Lights‌: These lights are usually installed on the top of high-rise buildings over 45 meters high to remind aircraft to avoid high-rise buildings. Navigation Obstruction Lights flash at night or in foggy weather to help pilots identify the location and height of buildings and prevent aircraft from hitting buildings‌.

‌Aviation Obstruction Light‌: This type of light has different flashing frequencies according to different light intensities. Low light should be always on, medium light should flash more than 20 times per minute, and high light should flash more than 70 times per minute. The purpose of aviation obstruction lights is to provide instructions for high-altitude flights at night to prevent accidents.

Working principle and installation requirement of building warning lights

Building warning lights usually flash 20 to 70 times per minute and can be clearly seen at night or in foggy weather. According to national regulations, high-rise buildings in cities with a height of more than 45 meters are required to install aviation obstruction lights. These lights are not only installed on the top of the building, but also distributed at various heights of the building so that pilots can better judge the outline of the building.

Background and trend of building warning lights

The history of building warning lights can be traced back to the early days of high-rise building construction. With the development of the aviation industry, the issue of safe distance between high-rise buildings and aircraft has become increasingly prominent, so installing warning lights has become an important measure to ensure flight safety. In the future, with the advancement of technology, more efficient and energy-saving warning light systems may appear to further improve flight safety.
