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

The vertical and horizontal distance between aerial obstruction lights should not be greater than 45 metres (i.e. if the top of an object is more than 45 metres above its floor, a barrier marker light must be added to its middle)
For chimneys or other buildings of a similar nature, the top obstruction marker light should be located between 1.5m and 3m from the top, taking into account the light pollution from the chimney
(For chimneys or other buildings of a similar nature, the top barrier light should be located between 1.5 and 3 metres from the top, taking into account the contamination of the light by the chimney).
Medium and high intensity aerial obstruction lights should be used for extremely tall objects above 150 metres.
For high voltage transmission cables of less than 150 metres, white medium intensity aerial obstruction lights can be set at the top of the tower.
No matter which kind of aviation obstacle light, its in different heights of aviation obstacle light of the number and arrangement, should be able to see from all sides of the object or object "group outline", and consider the obstacle mark light at the same time and sequential flashing, in order to achieve obvious warning effect.
