How does LED Aviation Obstruction Lights Work?

What is aircraft warning light? How does aircraft warning light work?


Aircraft warning lights ( aviation obstruction lights), are lighting devices that are installed to high structures and are used as collision avoidance measures.

Aircraft warning lights are designed and manufactured to warn aircrafts ( airplanes ), helicopters ( choppers ) for high altitude locations and structures. It is designed to be installed on tall towers, on the top of the high buildings, monopole masts, flag poles and all warning related applications.

Aviation obstruction lights operate by the control of microprocessor and photocell. Microprocessor automatically turns the aircraft warning light on when photocell detects darkness.

Microprocessor turns the aircraft warning light off when the photocell detects light.

Aviation obstruction light (AOL) is manufactured by the help of the latest technology LEDs which have long life-span ( 100.000 hours) and low energy consumption.

Wetra aviation obstruction light has 5 years factory warranty. Wetra aviation obstruction lights operate at 50 Hz, and the operating temperature range is -40 ° C / +55 ° C. The visibility distance of flashing aviation obstruction light is up to 10 km in the dark weather condition.
