The aviation obstacle light is a special light for the identification of obstacles and belongs to the category of aviation lighting equipment industry. In order to have a difference with the general lighting, aviation obstacle lights are not always on but flashing, low light intensity aviation obstacle lights are always on, medium light intensity aviation obstacle lights and high light intensity aviation obstacle lights are flashing, the flashing frequency is not less than 20 times/minute and not more than 60 times/minute. The function of the aviation obstacle light is to show the outline of the structure, so that the aircraft operator can judge the height and outline of the obstacle and play a warning role.Specification

Aviation obstacle lights are generally divided into low light intensity, medium light intensity and high light intensity three, aviation obstacle lights to the vertical and horizontal distance of more than 45 meters of the building and its facilities, can be three kinds of obstacle marking lights used in conjunction with each other. Classification of aviation obstacle lights
Below 45 metres from the ground, the surrounding open space should be set up low light intensity aviation obstacle lights, constant red light.
Buildings and their facilities above 45 metres and below 105 metres above ground level: medium light intensity type B aviation obstacle lights with red flashing, the flashing frequency should be between 20-60 times per minute, the effective light intensity is 2000 cd ± 25%.
Above 105 m from the ground and below 150 m use medium intensity type A aerial obstruction lights; white flashing with an effective light intensity (2000-20000 cd) ± 25%.
Buildings and their facilities above 150 m from the ground use high intensity obstacle marker lights and must be white flashing, the flashing frequency should be between 20-70 times per minute, the effective light intensity is the same as the background brightness and works 24 hours a day.
