Dialight develops LED beacon for broadcast towers
Dialight has announced what it calls the world’s first LED, medium-intensity, red-white flashing beacon for marking broadcast towers and other structures that pose a hazard to aircraft navigation.
The company said the LED beacon was designed to overcome problems affecting conventional lighting systems. Current Xenon and Incandescent technologies, the company said, are severely affected by vibration and extreme weather conditions, and offer a relatively short product life that in turn leads to high maintenance costs.
The LED beacon, Dialight said, can withstand high levels of vibration and the most severe environments. Operating temperatures range from -55 to +55 degrees Celsius, and it can withstand conditions including direct sunlight, wind blown rain, wind speeds of 200k/h, high humidity and salt fog, and has the same footprint as conventional technologies, making it easier to design in existing installations and products.
The new beacon has a solid-state design that enables 20,000 candela flashing white combined with a 2000 candela steady or flashing red all-LED obstruction light. It is designed to meet both Federal Aviation Administration (FAA) A/C 150/5345-43 and International Civil Aviation Organization (ICAO) Annex 14 July 1999 standards.
The LED dual beacon also offers reduced light pollution. It focuses the light selectively in the areas required and avoids spilling excess light toward the ground. A thermal management system effectively dissipates heat generated by the powerful light engine, helping to insure its long life in any environment. The beacon is also designed to meet NEMA 4/IP65 standards for moisture ingress. It carries a five-year performance warranty.
