Helideck obstruction lighting

Holland aviation Helideck obstruction lighting.

The marking or lighting of obstacles is intended to reduce hazards to an aircraft by indicating the presence of the obstacles.
Low-intensity obstacle lights, Type A or B, should be used where the object is a less extensive one and its height above the surrounding ground is less than 45 m.

An obstruction light used for aviation is meant to enhance the visibility of buildings or other fixed obstacles which may cause a distraction for an aircraft. Such obstruction lights are often placed on obstructions located near the heliports of airports.  

There are two common obstruction light types. * A red lamp that blinks or constantly burns. * A white lamp that flashes 40 times per minute. 

Old red obstruction lights or beacon lights used incandescent filament bulbs. Holland Aviation uses high-power LEDs. This is to improve the life cycle of the lights. This also has a beneficial effect on energy consumption. Another advantage of high-power LEDs is the longer lifespan of the LED lights.  

White flashing lights are for use during the daytime. During the night red lights are used. 

A white medium-intensity flashing obstruction light is used on buildings and structures that are between 61 and 152.4 meters (200-500 feet). The building should be painted if the building is taller than 152.4 meters (500 feet). When the building is higher than 213.4 meters (700 feet) a white high-intensity flashing obstruction light should be used. By night and by day these lights give the best visibility.  

The towers and masts should be painted in the color international orange or bands of equal length in white and red. This is to improve visibility during the daytime.  

Obstruction lights are used on tall buildings and structures. These can be towers, masts, water tanks, chimneys, cranes, electricity masts, wind turbines, and structures that are close to airports or heliports.
