LED Elevated Approach - FX862AP
The FX862AP, Elevated Approach Light, is part of a complete range of LED fixtures for runway and taxiway lighting systems. This application is high intensity, Uni-directional, white-light source, suitable for CAT I/II/III operations.
Use of the latest LED technology ensures the optimisation of power consumption is kept to a minimum, therefore the operating temperature is lower, thus improving the life of the LED module which is calculated to be greater than 75,000 hours.
Designed to meet the harsh environment the fixtures will operation in a temperature range of -55 °C to +55°C (-67 °F to +131°F) and has an ingress protection of IP67 (IEC 69598-1)
A standard FAA L823 style 1 connector is used to connect the fixture to the isolating transformer ensuring a water tight connection is made. On certain applications an option for an additional power lead can be requested.
The fixture operates between 2.8 – 6.6 amps which can be powered by either an IGBT type CCR, Ferro resonant or thyristor unit powering the airfield ground lighting (AGL) series circuit. The fixture is fully dimmable and follows the response curve of tungsten halogen lights as detailed in engineering brief 67 outlined in the Advisory Circular (AC) FAA 150/5345-53.
The fixture is compatible with existing circuits so there is no need to replace the constant current regulators (CCR), the isolating transformers, or field cables. However, we would recommend that the CCR is re tapped to match the circuit load ensuring the benefit of installing the fixtures are attained.
A ‘fail open’ monitoring facility is available which operates, should the LED array stop working with either an open, or short circuit condition. Use of LED light source eliminates filter replacement and colour shifts when viewed at various angles or at different CCR brilliancy settings.
