High intensity high obstacle light also known as aviation obstacle light is a safety device which is used to warn of high obstacles. It is consisted of light source, light cover, controller, power supply system etc. By the specific color light , it can alert pilots, drivers and pedestrians around to the presence of high obstacles to avoid accidents.
High-intensity obstacle lights are mainly used for extremely tall buildings and structures, such as high towers, bridges, radio and television towers, large-span cable-stayed bridges, and ultra-high voltage transmission line towers. These lamps are usually installed on obstacles to alert aircraft operators of the height and outline of obstacles to ensure flight safety.
These lights are usually installed on obstacles to alert aircraft operators to the height and outline of obstacles to ensure flight safety. High-intensity obstacle lights are suitable for obstacles that are more than 150 meters above the surrounding ground. These lights are usually white flashing lights with a flash frequency of between 20 and 70 times per minute. The effective light intensity depends on the background brightness and they work 24 hours a day.
How to choose the appropriate bulbs
The bulb of aviation obstacle light depends mainly on its light intensity and purpose. There are 3 types of aviation obstacle lights, including low intensity, medium intensity, high intensity from public information and their bulbs are diverse.
1.The obstacle lights with low intensity:
Bulb type: Incandescent light bulb or LED is usually used for light source of low light intensity. These kind of bulb future dim light and not easy to noticed at low altitude.
Model: Low-intensity obstacle lights are divided into four types: A, B, C, and D. Among them, A and B are red constant light, C and D are flashing, but the colors are different (C is yellow or blue light source, D is yellow light source).
Application: Mainly used to identify tall buildings and aircraft in the low sky, such as control towers near airports, passenger planes flying over airports, etc.
2.The obstacle lights with medium intensity:
Bulb type:The light source of medium-intensity obstruction lights is generally halogen bulbs or LEDs.
Model: Medium-intensity obstruction lights include two types: Type A and Type B. Type A is white flashing, and Type B is red flashing (there are also claims that Type B is medium-intensity constant light, but it is usually more common for Type A to be flashing).
Application:suitable for high-altitude aircraft, tall buildings, and other prominent obstacle, such as bridges, tall buildings, chimneys, etc. around airports.
3.The obstacle lights with high intensity:
Bulb type:The light source of high-intensity obstruction lights is mainly xenon lamp or LED. Because these bulbs can emit very strong light to make sure that pilots see clearly them from long distance.
Model: there are also two types of high intensity obstacle light, Type A and Type B, they are both white flashing light. The difference between them is that they have different light intensity during the day, dusk or down and night (Type A is 200,000 candela during the day, and Type B is 100,000 candela during the day).
Application:mainly used to mark very tall buildings and important obstacles, such as TV towers, high-voltage towers, etc.
Summary
In general, high-intensity obstacle lights, as a safety precaution, have been widely applied with important functions. They can provide good visual effects at night and effectively stop safety risks caused by high obstacles.The types of bulbs for aviation obstruction lights is different according to their light intensity and purpose, mainly including incandescent bulbs, LEDs, halogen bulbs, and xenon lamps. When choosing aviation obstruction lights, you need to choose the appropriate bulb type and light intensity level based on the specific usage scenario and needs.
