First, the Civil Aviation Authority of the relevant provisions: the National Civil Aviation Authority of the aviation obstruction lights set out in detail, the excerpts are as follows: high-rise buildings (such as high-rise buildings, power plants chimney, communication tower or other similar buildings) must be set at the top One or several air obstruction lights to assists in safety. The same time as The obstruction light must be installed between the top of the building between 1.2 m and 3 m. The building is higher than the ground over 45 meters above the ground must be added in the middle layer of obstruction lights, add the middle layer of obstruction light to the location of each lamp as far as possible between the distance as much as possible, using low, medium light obstruction lights The distance must not exceed 45 meters. (Set the number of layers of lights N = material height / 45 meters) the vast number of buildings, set the lights should take full account of each corner of the building, to be done from each corner can see the contours of the building, horizontal To refer to each layer ≤ 45 m design requirements. Higher than 150 meters high building, and then the top must be set high light strong aviation obstruction lights, and to be used in the combination of light intensity obstruction lights to show its presence. Second, a variety of light barrier lights selection (H for the building height) 45 m ≤ H ≤ 60 meters, using low light intensity GZ220-6, GZ220-7 type obstruction light 60 meters ≤ H ≤ 105 meters, Strong GZ220-7, 7B and GZ-155 combination of the use of 105 meters ≤ H ≤ 150 meters, the use of high school light intensity GZ220-7B and GZ-155 combination of the use of H ≥ 150 meters, using high light intensity GZ-155 And GZ-90 combination of light design requirements of the use of Suzhou Haixiang beacon Electric Equipment Co., Ltd. production of GZ series of long-life aviation obstruction lights. Third, the effective light intensity of the obstruction lights are: 1) low light intensity obstruction light effective light intensity 150cd, red flash or often 2) light intensity obstruction light effective light intensity 1600cd, generally red flash 3) high light intensity effective light intensity 4000cd, usually white flash (background intensity <50cd) Fourth, lightning protection: 1) the top of the obstruction lights should be installed lightning arrester, lightning arrester should be part of the lightning protection and other facilities are closely linked. 2) the middle part of the building lights, the need to use metal mesh cover to be protected, and the metal parts of the lamp are well grounded Set the relevant standards, regulations and recommendations for aviation obstruction lights (consistent with ICAO) First, the Civil Aviation Authority of the relevant provisions: the National Civil Aviation Authority of the aviation obstruction lights set out in detail, the excerpts are as follows: high-rise buildings (such as high-rise buildings, power plants chimney, communication tower or other similar buildings) must be set at the top One or several air obstruction lights to assists in safety.
