Air Barrier Light Acts As A Warning Aug 17, 2017



According to national standards, the top of the ground above 45 meters above the high-rise building must set beacon. In order to be different from the general purpose lighting, the beacon light is not bright but shiny, the flash frequency is not less than 20 times per minute, Aviation Obstruction Light not more than 70 times per minute.

Air Barrier Indicator category

The aviation obstacle lamp generally divides into the low light intensity, the medium light strong and the high three kinds, the aviation barrier lamp vertical and the horizontal distance is larger than 45 meters construction and the facility, may the three kinds of aviation barrier lamp can cooperate with each other.

90 meters above the ground building and its facilities: the use of light strong aviation obstacle lights for red flash, flash frequency should be between 20-60 times per minute, the flash of effective light intensity is not less than 1600CD, or the use of Red High aviation barrier lamp, Aviation Obstruction Light make its flash effect more obvious. 150 meters above the ground building and its facilities, the use of high aviation barrier lights and must be a white flash, flash frequency should be 20-70 times per minute, effective light intensity with the background brightness.

Air Barrier Light distribution

Obstacles to the installation of their aviation barrier lights should be marked with the highest point of obstruction and the most marginal (that is, view height and width) to set up air barrier lights, middle-tier spacing must not be greater than 45 meters, the city of more than hundred meters high buildings in particular to consider the middle layer plus air barrier lamp vertical and horizontal distance should not be greater than 45 meters (that is, if the top of the object above its ground 45 meters above, must be in the middle of the sign light

For chimneys or other buildings of a similar nature, the top air barrier lamp shall be situated at the top 1.5-3 m, and the air barrier light may be located 4-6 metres below the chimney port, taking into account the chimney's pollution to the luminaire.

The ultra-high object above 150 meters should be used in conjunction with the high aviation obstacle lamp.

For less than 150 meters high high-voltage transmission cable, the tower can be located at the top of the white light in the light strong aviation obstacle lights. No

On which kind of aviation obstacle lamp, the number and arrangement of the airborne obstacle lights at different heights, it should be able to see the object or object "group contour" from all aspects, Aviation Obstruction Light and consider the simultaneous and sequential flashing of the aviation obstacle light to achieve the obvious warning effect.

According to annex 14 of the International Standard and recommended measures (mh/t60121999) issued by ICAO, the aviation obstacle light is divided into three categories: low intensity aviation obstacle light, medium light and strong aviation obstacle lamp and high aviation obstacle lamp.

1, low light strong aviation obstacle lamp is constant luminous, red, peak light is stronger than the other. 5CD, is not commonly used alone, but must be with the light intensity, high obstruction lamp with the use.

2, in light of the strong aviation barrier lights according to the requirements of three kinds of luminous: (A, medium-light strong type a air barrier lights for the white flash, B, medium-light strong B-type air barrier lights for the red Flash).

3, the high aviation barrier lamp according to the luminous requirements to be divided into two kinds: (A, high a type aviation obstacle lamp is the white flash, B, high B type aviation obstacle lamp is the white flash).

Distribution of airborne barrier lights: Obstacles to the setting of their barrier lights should mark the highest point and the edge of the obstacle (that is, apparent height and width).
