Aviation Obstacle Aircraft Warning Lights For Lighting Protection

Aviation obstacle lights are generally divided into low light intensity, medium light intensity and high light intensity three, aviation obstacle lights vertical and horizontal distance greater than 45 meters of the building and its facilities, can be three kinds of obstacle marker lights used in conjunction with each other. Aviation obstacle lights classification
Below 45 meters from the ground, around the more open places should be set up low light intensity aviation obstacle lights, constant red light.
More than 45 meters from the ground 105 meters below the building and its facilities: the use of medium light intensity B-type aviation obstacle lights for red flashing, flashing frequency should be between 20-60 times per minute, the effective light intensity of 2000cd ± 25%.
More than 105 meters from the ground 150 meters below the use of medium light intensity A-type aviation obstacle lights; white light flashing, effective light intensity (2000-20000cd) ± 25%.
More than 150 meters from the ground buildings and their facilities, the use of high light intensity obstacle marker lights, and must be white flashing, flashing frequency should be between 20-70 times per minute, the effective light intensity and background brightness, all-weather 24 hours work.
Obstacle should be set on the obstacle marker lights, in the highest point of the obstacle and the most edge (that is, depending on the height and width) set aviation obstacle lights, the middle layer of the spacing shall not be greater than 45 meters, the city more than 100 meters of ultra-high buildings especially to consider the middle layer to add aviation obstacle lights.
The vertical and horizontal distance of aviation obstacle lights should not be greater than 45 meters (i.e. if the top of the object is higher than its ground 45 meters, must be installed in the middle of the additional obstacle marker lights)
For chimneys or other buildings of similar nature, the obstacle marker lights on top of them should be located between 1.5-3 meters, while taking into account the pollution of light by chimneys
Pollution, the obstacle marker light can be located in the chimney mouth below 4-6 meters.
For higher than 150 meters of ultra-high objects, should be used in conjunction with the high intensity aviation obstacle lights.
For less than 150 meters of high-voltage transmission cable, can be set in the tower top white light medium light intensity aviation obstacle lights.
Regardless of which aviation obstacle lights, different heights of the number and arrangement of aviation obstacle lights, should be able to see from all sides of the object or object "group outline", and consider the obstacle mark lights while flashing sequentially, in order to achieve a clear warning effect.
