OPTIONS:
Led Aviation obstruction lights (Led Aircraft warning lights)
Aviation obstruction lights (Aircraft warning lights) are lighting devices that are installed to high structures and are used as collision avoidance measures. Aviation obstruction lights make structures more visible to passing aircraft and are usually used at night, although they can be used during the day as well. Aviation obstruction lights need to be of sufficient brightness in order to be visible for miles around the structure.
International Civil Aviation Organization (ICAO) is one of the leading authority that has regulations and standards about aircraft warning lights. Due to the height of the structure, the quantity and intensity of the aircraft warning light can vary.
The air traffic has increased exponentially and the use of aircraft warning lights have become either a must or recommendation for most applications. Municipalities, states and governments may have regulations concerning requirements of high structures. So, marking the high structures and making them more visible to aircrafts, can be a legal duty according to the location.
Considering ICAO standards and existing applications, red color aviation obstruction light is widespreadly used. Also various color options are available such as yellow, orange, blue, green, white color aircraft warning lights can be preffered for different applications.
Generally, aircraft warning light (AWL) system includes microprocessor and photocell. In most cases, photocell is used to detect insufficient ambient light, and the aircraft warning light starts working ( steady or flashing mode).
Wetra aircraft warning lights uses LED (light-emitting diode) technology which enables long life-span (100.000 hours) ,high light per heat efficiency, low electricity consumption, low heat loss Wetra aircraft warning light meets IP 65 standards. The policarbon cap of Wetra aviation obstruction lights is splashproof.
Aviation obstruction lights are also named as aircraft warning lights, obstruction marking light, mast obstruction light, led aviation obstacle lights.

Obstacle lighting systems mark dangers for aviation. Especially under bad weather conditions, pilots have to rely on their correct function.
Marking and lighting of aviation obstacles is based on several regulations and requirements. Set of regulations of the international aviation organizations may be applied in addition to regulations published by the local authorities.
Aircraft Warning Lights are used to warn the presence of high buildings: skyscrapers, towers, chimneys, wind generators, offshore platforms, etc.; ensuring a safe air navigation.
According to ICAO - International Civil Aviation Organization Annex 14 regulations, each tall structure must have aviation obstruction light on it. Depending on the height of the structure, the aviation obstruction lights can have different intensities such as low intensity aviation obstruction light, medium intensity aviation obstruction light, high intensity aviation obstruction light, exproof aviation obstruction light.

International Rules / Regulations
The International Civil Authority Organization (ICAO), in 2013 has published the sixth edition of its International Standards and Recommended Practices for Aerodromes.
The Aerodromes design and operation, Annex 14, Volume I, Chapter 6 and Aerodrome design manual, Visual aids, Chapter 4 are the regulations where all the elevated structures manufacturers should refer and being compliant to.
Tall structures and buildings, may be dangerous obstacles for aircrafts. Make them more visible is very important to avoid accidents and guarantee a safe air navigation.
The measure used as collision avoidance and recommended by ICAO and all aviation authorities to warn the presence of vertical extended structures, is mark with red/white painting the structure or install
Aircraft Warning Lights (AWL):
1. An object should be colored to show alternating contrasting bands […] orange and white should be used [..](ICAO Aerodromes, 2013, Vol.I, Ch.6, 6.2.4)
2. A fixed obstacle above a horizontal surface should be marked and, if the aerodrome is used at night, lighted (ICAO Aerodromes, 2013, Vol.I, Ch.6, 6.1.4)
3. The marking may be omitted when the obstacle is lighted on day (ICAO Aerodromes, 2009, Vol.I, Ch.6, 6.1.1 et seq.)
These lighting devices could be used during the night, but also during the day when bad weather conditions could reduce pilot’s visibility. According to the height, extension, type and location of the structure, specific types of Aircraft Warning Lights must be used: low or high intensity, steady burning or flashing light, red or white light, explosion proof or IP body, etc.

Since this date all products offered for sale, or put into service, within the European Community will have to conform to the ATEX Directive 94/9/EC.
Superiorities of Luxsolar LED Aviation Obstruction Lights - Aids to Navigation
LUXSOLAR LED beacons are the best solution available on the market due to a series of innovative and
unique features (all patented):
1. Cooling system: a good cooling system and high working performance for the beacon is crucial to
guarantee long life, especially where natural ambient temperature is very high. LUXSOLAR solved
this problem manufacturing its warning lights with a central heat sink that facilitates a forced cooling.
Thanks to a wind collector on the bottom and an upper wind cone, fresh air fl ows naturally inside
and outside the body without obstacles.
2. Lenses: the PMMA patented lenses used emit a stabilized light output between -1° and +3° as per
ICAO recommendation.
3. Low wind load factor
4. GORATEX System: all LUXSOLAR’s beacons are provided with a system that avoids condensation
5. Infrared LEDs available on all beacons, visible with aviation infrared fl ight helmets
6. Customizable solution: all our beacons can be manufactured as per customer’s requirement
What is LED and Why is LED preffered in Luxsolar aviation obstruction lights?
In 1962 Nick Holonyak Jr. developed the first LED, transforming the lighting world.
LED is acronym of Light Emitting Diode. The functioning of this device is very easy: the processed silicon
diode (semiconductor) emits light when crossed by electric current.
At the beginning, LEDs were available only in red color and were used as warning lights to signal the
presence of tension in electronic circuits. Subsequently, processing the diode with other materials, the
production of green and yellow LEDs started. The production of blue LEDs - the ones with the highest
efficiency - began in the 90es. While mixing blue with other colors, it was possible generate any other
color. For example, PC monitors use only these colors to create a limitless range of shades.
In 1995 Eng. Roberto Barbieri of Cardiff University created the first high efficiency LEDs, and
beginning from 20 lumen/watt, today LEDs have reached 180 lumen/watt of luminous efficiency.
Thanks to a series of features and its long-life, LED is the best lighting source now available on the market.
In some installations, where a frequent maintenance is not possible or is extremely dangerous, LED light
is the best way to avoid risks and save money.
INCANDESCENCE
Incandescent lighting sources, put inside Fresnel lenses red globes directing light horizontally, were used
both in low intensity (>32 candles) and medium intensity (>2.000 candles) night applications.
Due to incandescent lamps’ short life expectancy (less than 1 year), it was necessary to install two
lighting bodies: the main one and its replacement.The limited life expectancy (2.000 hours) and the
elevated power consumption (only 15 lumen produced with 1W) have made this source obsolete and
its production banned in the European Union since 2009.
Fluorescent lighting sources, put inside red globes are used in low intensity (>32 candles) night applications.
Not being this source punctiform, it requires high power to reach 32 candles. It has got an average life
of more than 5 years.
Xenon lighting sources, put inside Fresnel lenses red globes are used both in medium intensity (>2000
candles) night applications, directing light horizontally, and in daytime applications - using reflectors
- with up to 200.000 candles white flashes.
The limited life expectancy (1.000 hours) made this kind of source expensive, in fact it is necessary to
install two lighting bodies: the main one and its replacement.
LED lighting sources are used in low intensity (>32 candles), medium intensity (from >2000 to >20000
candles) and high intensity (200.000 candles) applications, in white or aviation red colour.
Due to its long life expectancy (100.000 hours) and its low power consumption LED source is the most
reliable lighting source available.
INTERNATIonAL REGULATIONS FOR
AIRCRAFT WARNING LIGHTS
MEAN TIME BETWEEN FAILURE
All components, including the light source, shall be designed for ease of maintenance and to provide
the specified performance for a period of at least one year without maintenance. With preventive
maintenance performed on an annual basis, the system MTBF (Mean Time Between Failure) shall not be
less than six months (ICAO Aerodromes, 2013, Vol.I, Ch.6, 14.6.2).
Due to their short operating life, Incandescence and Xenon warning beacons must be provided with an
emergency beacon to be compliant with ICAO request of a high MTBF. This second beacon obstructs
the main AWL light beam. LUXSOLAR LED beacons have instead normal and emergency LEDs in the
same fixture galvanically separated, so with LED as light source and a proper driving circuit, a longer
MTBF is guaranteed and the installation of an emergency light is avoided.
The type, the number and the positioning of Aircraft Warning Lights depends on:
1. Structure’s height and proximity to airports
2. External diameter of the structure (ICAO Aerodromes, 2013, Vol.I, Ch.6, 14.6.9)
• Up to 6mt = require nr. 3 beacons
• From 6mt to 30mt = require nr. 4 beacons
• From 30mt to 60mt = require nr. 6 beacons
• More than 60mt = require nr. 8 beacons
The number and arrangement of low, medium or high intensity obstacle lights, at each level to be
marked, shall be such that the object is indicated from every angle in azimuth. Where a light is shielded
in any direction by another, additional lights shall be provided (ICAO Aerodromes, 2013, Vol.I, Ch.6,
6.3.22).
As per ICAO recommendation low, medium and high intensity Aircraft Warning Lights should be:
1. Low-intensity obstacle lights on fixed objects, Type A and B, shall be fixed red lights. (ICAO Aerodromes,
2013, Vol.I, Ch.6, 6.3.23)
2. Medium-intensity obstacle lights, Type A, shall be flashing-white lights, Type B, shall be flashing-red
lights and Type C shall be fixed-red lights. (ICAO Aerodromes, 2013, Vol.I, Ch.6, 6.3.30).
3. Medium-intensity obstacle lights, Type A and B, located on an object shall flash simultaneously (ICAO
Aerodromes, 2013, Vol.I, Ch.6, 6.3.32).
4. High-intensity obstacle lights, Type A and B, shall be flashing-white lights. (ICAO Aerodromes, 2013,
Vol.I, Ch.6, 6.3.33)
5. High-intensity obstacle lights, Type A, located on an object shall flash simultaneously. (ICAO
Aerodromes, 2013, Vol.I, Ch.6, 6.3.35)
6. High-intensity obstacle lights, Type B, indicating the presence of a tower supporting overhead wires,
cables, etc., should flash sequentially (ICAO Aerodromes, 2013, Vol.I, Ch.6, 6.3.36).
