Lighting devices that are installed on structures to avoid aircraft collision are called aircraft warning lights. They are high-intensity and are installed as a collision avoidance measure. Incoming aircraft can easily spot them because they are very visible. They find use at night in most cases, but they can also be used during the day. Aircraft warning lights on buildings remain visible from miles away. They are bright and may be steady or they may be made to blink for more efficiency.
Generally, only two types of these lights exist, that is, white flashers and red lamps. Red lamps are programmed to remain on throughout or to go on and off at a certain rate. The rate is usually low and does not change even though it can be changed. White flashers are normally xenon discharge flashers. Red lamps are gaining more popularity in some countries such as the UK over white flashers.
The red lamps have incandescent filament bulbs installed in them. They are made with ruggedized design in order to achieve a higher lifespan since they usually have a rather short one. They are also run below the usually operating power to improve lifespan. In the recent past, high-power red LEDs are being used to replace incandescent bulbs.
The lifespan of LED-based lamps is much longer, which helps to reduce maintenance costs while improving reliability. Medium-intensity white strobes have been developed by some manufacturers based on the LED technology to replace xenon flashers. This invention has increased the desire for white flashers in the US. Most buildings thus have white flashers during daytime and red lamps at night.
Highly populated and urban areas tend to have red lamps installed more commonly. Red lamps are preferred because they can be seen more easily from a height and distance. White flashers are also used in urban areas but not very commonly. The ability of white flashers to blend with background lights makes them less effective for the purpose they are supposed to serve. Since rural areas does not have background lights that may cause interference, white flashers are used more commonly.
In general, the lamps are installed on any kinds of tall structure. Examples of structures they are installed on include water tanks, tall buildings, wind turbines, electricity pylons, broadcast towers, chimneys, cranes, and broadcast masts. They are also installed on shorter structures that are located close to an airstrip or airport. This is done to warn landing aircraft and those that are taking off the ground.
Usually, lights are organized in sets of two or more lamps up the structure. The top of the structure will have a set of lamps and other sets will be placed at predetermined intervals downwards. The height of the structure may determine how many lamps are comprised in each set at each interval. Similarly, the height determines the interval between lamps and the number of sets.
Major concern related to these lamps is that they contribute to light trespassing. Most people located in places with the lamps usually complain of light trespass. Light pollution has also been reported together with towerkill of birds.
