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.
Introduction Editorial Podcast
Aviation obstacle light (Aviation Obstruction light), also known as
navigation light equipment, is a special light to mark the
obstacle, belongs to the navigation light equipment industry,
aviation obstacle light is its under-seat light type range. In
order to have a difference with the general lighting, aviation
obstacle light is not always on but flashing, low light intensity
aviation obstacle light is always on, medium light intensity
aviation obstacle light and high light intensity aviation obstacle
light is flashing, flashing frequency is not less than 20 times per
minute, not higher than 60 times per minute. The role of aviation
obstacle lights is to show the outline of the structure, so that
the aircraft operator can judge the height and outline of the
obstacle, play a warning role.
